Limb braking device and braking management system

Technical Field

The invention relates to the technical field of medical auxiliary equipment, in particular to a limb braking device and a braking management system, wherein the classification number is A61G.

Background

Coronary angiography refers to percutaneous aspiration of peripheral arteries to deliver coronary angiography tubing to the root of the aorta or to the left and right coronary ostia, and to bolus contrast media to visualize the coronary arteries and thereby determine whether the coronary arteries are diseased. If the coronary artery lesion is narrow, the coronary artery lesion is in a part and the degree of the stenosis is displayed, and the feasibility and the method of treatment are shown. Coronary angiography is one of the common examination methods for cardiovascular diagnosis and also one of the means for diagnosing coronary heart disease. There are two options for the peripheral artery, one via the femoral artery path and the other via the radial artery path. In order to avoid hematoma caused by local hemorrhage after puncture, a heavy object such as a sand bag is required to press the puncture position for 6 hours after operation, the patient lies on the bed for 24 hours, and meanwhile, the operation limb is braked for 12 hours.

The technical proposal is as follows: the femoral artery puncture postoperative care device is characterized by comprising a bed body, wherein the bed body comprises a bed plate, a rectangular opening is formed in the position, close to a bed tail, of the bed plate, a leg clamping mechanism capable of ascending and descending is arranged below the rectangular opening on the bed body, and a leg massage mechanism is arranged on one side of the upper portion of the leg clamping mechanism.

CN114795630a proposes a post-interventional operation puncture side leg braking device, which effectively solves the problems that the existing fixing device can not fix the hip joint of the patient and the lower limb at the post-surgical puncture side together and can not press and stop bleeding the puncture point. The device comprises a braking part and a pressing part, wherein the braking part comprises three constraint rings with the same structure and a plurality of fixing belts, the size of the constraint ring at the forefront side is matched with the waist of a patient, and the sizes of the two constraint rings at the rear side are matched with the lower limbs of the patient; the constraint ring comprises two base plates, the two base plates are movably connected, a three-head connecting ring is arranged at the outer side end of the base plate, and a binding belt is arranged at the lower side of the three-head connecting ring on the right side; the inner side end of the fixing belt is movably connected with the three-head connecting ring; the two constraint rings at the front side are connected through a connecting band group, and the pressing component is movably connected with the connecting band group; the pressing part comprises a connecting seat, a threaded pipe is rotationally connected to the lower side of the connecting seat, an extension column is connected to the inner thread of the threaded pipe, and a pressing ball is arranged at the lower end of the extension column.

The prior art generally focuses only on how to brake the operative limbs of the patient, but the braking scheme cannot be flexibly adjusted according to the actual physiological state of the patient during the braking process, so that even if the purpose of braking is achieved, other damage can be caused to the patient. Furthermore, the prior art is too much concerned with the braking effect, and neglecting that the patient whose operative limb is braked after the intervention should still be properly active to wait for the recovery of the condition and to reduce the occurrence of complications, in particular the need to avoid the formation of thrombi.

Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Disclosure of Invention

The prior art has developed limb braking solutions that enable active limiting of the patient and facilitate postoperative care. For example, patent document CN114983715A discloses a nursing support for cerebral vascular diseases after interventional operation, comprising a foot limiting frame, a foot movable limiting mechanism is mounted on the foot limiting frame, the foot limiting frame is connected with a U-shaped supporting plate through a sliding connection mechanism, a moving groove is formed in the upper part of the U-shaped supporting plate, a leg limiting mechanism is connected to the moving groove in a sliding manner, a wound pressurizing mechanism is inserted into the end part of the U-shaped supporting plate, and two sides of the U-shaped supporting plate are connected with binding bands; the nursing staff places the whole nursing support of this technical scheme on patient's upper portion, then fixes on the sick bed through the bandage, and foot's activity stop gear provides spacingly for patient's activity, uses shank stop gear to carry out spacing fixedly to patient's shank to provide pressure to the wound through wound pressurization mechanism and wrap, excellent in use effect. However, on one hand, the device for limiting the movement of the leg in the technical scheme can only realize the braking management of the leg in a vertical pressure applying manner, and cannot realize the detection of the swelling condition of the operative limb through the leg fixing device. On the other hand, the pressurizing mechanism and the leg movable limiting mechanism in the technical scheme have no interrelated control relationship, and the limb braking component cannot be dynamically adjusted according to the specific pressurizing process of the leg puncture point of the patient, so that the occurrence of complications caused by the fact that the limb is in a limiting state for a long time is reduced.

In order to solve the above-mentioned problems, the present invention provides a limb brake device and a brake management system.

The invention discloses a limb braking device, which comprises: a braking unit for forcedly braking the operative limb of the patient; a monitoring unit for acquiring one or more data information related to the patient; and the processing unit is used for receiving the data information sent by the monitoring unit and analyzing and processing the data information so as to generate a control signal.

The fixing part of the brake unit comprises one or more fixing parts sleeved on the operative limb of the patient through a reserved hollow area, and the first air bag part arranged on the inner side of the fixing part facing the hollow area can occupy at least part of the hollow area in an inflatable mode so as to limit the movement of the operative limb of the patient.

The prior art has presented a technical solution for realizing the measurement of limb parameters by arranging an air bag structure inside the fixing device. For example, patent document CN109938693a discloses a device for measuring mechanical properties of soft tissue of a stump, which comprises a rigid shell, an air bag is arranged on the inner side of the rigid shell, a gas with a certain pressure is filled in the air bag, a yielding hole is formed on the side surface of the rigid shell, and the indentation measuring device is arranged on the rigid shell. The technical proposal fully simulates the compression state of the prosthetic socket on the residual limb in the measurement process, and avoids the extrusion action of surrounding soft tissues on the measurement part as much as possible. However, the balloon assembly in this solution is only used for compression fixation of the residual limb and sufficiently simulates the fit of the prosthetic socket and the residual limb during the measurement, whereby no detection of the limb parameters can be achieved, which is significantly different from the effect of the balloon assembly of the present invention. Compared with the prior art, the brake unit is sleeved on the operative limb of the patient through the fixing piece arranged in the fixing part, and the first air bag piece capable of fixing the operative limb of the patient in an inflatable mode is arranged on the inner side of the fixing piece. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to fix the patient's limb and detect the parameters of the partially fixed patient's limb, thereby judging whether the patient's limb swells or not according to the obtained detection parameters. Specifically, the monitoring units are arranged on the inner side wall of the fixing piece in a circumferentially spaced mode, a plurality of first monitoring parts can acquire the shortest distance between the monitoring units and the surface of the first air bag piece, and therefore the processing unit can judge whether the operation limb of a patient is swollen or not by calculating the perimeter of the surface of the first air bag piece.

The first monitoring portion may be configured as an infrared ranging sensor to measure the shortest distance of each sensor from the first balloon member surface, where the first balloon member surface refers to the surface in contact with the skin of the patient, using modulated infrared light, so that the processing unit may calculate the circumference of the first balloon member surface, which may characterize the local circumference of the patient's limb (i.e. leg circumference or arm circumference), from the shortest distance acquired by each sensor. Preferably, when the first monitoring portion obtains the distance information, the processing unit may regulate and control the inflation state of the first air bag member, so as to determine the fitting degree of the first air bag member and the operative limb of the patient by making the air pressure value of the first air bag member reach the set threshold value, thereby avoiding measurement deviation caused by different extrusion degrees of the air bag to the operative limb of the patient. Further, the processing unit can judge whether the limb swelling occurs at the part according to the local circumference of the operative limb of the patient, and can generate a corresponding response scheme or report to corresponding medical staff by using the communication unit when the limb swelling is determined.

According to a preferred embodiment, the fixing part can be arranged on the supporting part of the brake unit in a position-adjustable manner through the interface, wherein the inflation amount of the first airbag part arranged in the first fixing part and/or the second fixing part arranged in the fixing part can be adjusted according to the control signal generated after the processing unit analyzes and processes the data information acquired by the monitoring unit.

The support part is approximately flat plate-shaped, so that a patient can lie on the support part, wherein a plurality of interfaces can be arranged on the support part for externally connecting other parts to realize the braking of the limb of the patient, and particularly the fixing of the operative limb of the patient. The first fixing piece and the second fixing piece which are configured by the fixing part can be constructed into a hollow columnar structure so as to be sleeved outside the operative limb of the patient, wherein the hollow area reserved by the first fixing piece and the second fixing piece can accommodate the corresponding part of the operative limb of the patient and has at least partial movable range.

According to a preferred embodiment, the pressing part of the brake unit can be arranged on the supporting part through the interface, the pressing part can press the puncture part through the arranged mechanical structure with adjustable pressing force, and the pressing force applied by the pressing part can be adjusted according to the control signal generated after the processing unit analyzes and processes the data information acquired by the monitoring unit.

Compared with the prior art, the compression part can adjust specific compression parameters according to the control signals generated after the processing unit analyzes and processes the data information acquired by the monitoring unit. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to dynamically adjust the compression parameters according to the specific recovery state of the operative limb of the patient so as to prevent the puncture local hemorrhage from forming hematoma and avoid thrombus formation caused by excessive compression or puncture local hemorrhage caused by insufficient compression. Specifically, the puncture site may be pressed for several hours using a pressing part, wherein the pressing part for pressing the puncture site may be configured as a weight, such as a sandbag or a mechanical structure connected to a transmission mechanism. When the compression part is configured into a mechanical structure, the compression part can adjust the compression force applied to the puncture part according to the control signal generated by the processing unit, so that the condition that the distal blood supply is influenced due to overlarge compression force or the puncture part is bleeding due to overlarge compression force is avoided.

According to a preferred embodiment, the monitoring unit comprises a second monitoring portion arranged in the area of the patient's heel for acquiring a pressure distribution of the heel on the side of the patient's limb, wherein the processing unit is able to determine the pressure extreme point as the patient's heel end point based on the pressure distribution acquired by the second monitoring portion.

Compared with the prior art, the monitoring unit can judge the movement range of the foot according to the acquired heel pressure distribution condition of the side where the operative limb of the patient is positioned. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to adjust the braking degree of the fixing part according to the pressure distribution change of the foot of the patient so as to ensure that the limb braking effect is always kept within a preset range. Specifically, when a patient's limb is immobilized, it is often difficult to perform a wide range of movements on the foot of the side of the limb, and it is possible to determine whether the degree of immobilization of the immobilization portion is up to standard by analyzing the pressure distribution of the heel of the side of the limb. Further, when the processing unit judges that the foot of the patient still can perform activities beyond the set range according to the change condition of the pressure distribution of the heel on the side where the operative limb of the patient is located, the braking degree of the fixing part can be improved by increasing the inflation amount of the first air bag member.

According to a preferred embodiment, the monitoring unit comprises a third monitoring part and/or a fourth monitoring part for acquiring data information related to the foot of the patient, wherein the processing unit is capable of judging whether the degree of braking of the fixing part and/or the degree of compression of the compression part is excessive or not based on the image information acquired by the third monitoring part and/or the temperature information acquired by the fourth monitoring part.

When the processing unit judges the insufficient blood supply of the feet of the patient according to the skin color and/or the temperature of the feet of the patient on the side where the operative limbs are positioned, the normal blood supply of the limb tips can be ensured by reducing the inflation amount of the first air bag piece and/or reducing the compression force of the compression part.

According to a preferred embodiment, the second monitoring portion may be configured in the moving portion of the movable unit, where the moving portion disposed in the area where the foot of the patient is located may provide an adjustable supporting force for the foot of the patient, so that the moving portion adjusts the supporting force of each point according to the distribution scheme of the supporting force generated by the processing unit, thereby implementing adjustment of the posture of the foot of the patient.

Most patients have no clear concept of the movable joints in the event that the limb is braked, and the healthcare staff may not say in detail, resulting in either immobility or tampering with the patient. The movement part configured by the movable unit can guide the foot of a patient to perform proper movement, can activate the calf muscle group and promote smooth blood circulation so as to prevent thrombosis. Furthermore, the patient can be prevented from being disturbed under the condition of no guidance under the driving of the movement part, and bleeding and other conditions of the puncture part are further avoided.

According to a preferred embodiment, the movement part comprises a plurality of second balloon members arranged in a specific arrangement, each second balloon member being capable of having a respective independent support area in a separately regulated manner, so that the distribution scheme of the support force of the movement part generated by the processing unit can be converted into the inflation and deflation scheme of each second balloon member.

When an object is placed on the supporting area of any second air bag piece, the supporting force applied by the second air bag piece can be changed by adjusting the inflation amount of the second air bag piece, so that the object can be pushed up or sunk down; when an object is placed on the support areas of the plurality of second air bag members, the distribution scheme of the support force applied by the moving part can be changed by adjusting the inflation amount of one or more of the second air bag members, so that the object can be adjusted to a specified posture. Further, if the object is a foot on the side of the patient's limb, the foot placed on the movement portion may be supported by the plurality of second air bag members, and the movement required for completing the prescribed movement may be performed when the inflation amount of one or more of the second air bag members is adjusted.

According to a preferred embodiment, after a preset compression time has been reached, the compression part is removable from the patient puncture site and in a ready state such that the compression part can be switched to an operating state for a special period of time, wherein the special period of time comprises a period of time from a time point at which the special event is triggered to a time point at which the special event is completed.

Compared with the prior art, the compression part can adaptively start the working state according to the special event triggered by the patient in the special period. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to prevent the accidental physical state mutation of the patient from generating secondary impact injury to the wound of the puncture part. In particular, a special event is a thing that may impact a wound at a patient puncture site, wherein the special event may be, for example, a cough or a drain, etc. Since the physical vibration caused by the cough is likely to cause local impact, particularly for the puncture site, the wound of the site is more susceptible to the impact caused by the cough, and therefore, the compression part is used for temporarily slightly pressing the puncture site before the patient finishes the cough action, so that the impact on the wound is reduced. When the pressing part in the ready state is switched to the working state, the force applied by the pressing part is preset as 'light pressure' by the processing unit so as to smoothly spend a special time.

According to a preferred embodiment, when the special event is a cough, the processing unit is capable of receiving a signal accompanied by a cough intention transmitted by the wearable device configured with the sensor through the communication unit, and driving the pressing part to switch to the working state in response to the signal, wherein the wearable device is capable of judging whether the patient has the cough intention of performing part of the cough action through one or more sensors.

This is because when the patient has a cough intention, the patient exhales hard against the closed glottis, which can cause a sudden increase in the circulating blood pressure, and this phenomenon can be expressed as a sudden drop in the acquired data information of the blood volume in the detection of the photoplethysmography sensor, and therefore, the sudden drop in the acquired data information of the photoplethysmography sensor is used as an early warning signal representing the cough intention, so that countermeasures can be taken in advance. Further, the patient is in a state of limited movement during braking, and is in a state of lying down and resting down in most cases, the data information acquired by the acceleration sensor is relatively stable, but when the data information acquired by the photoplethysmography sensor suddenly drops, the data information acquired by the acceleration sensor is disturbed, so that the patient can be further verified to be performing a cough action of forcefully exhaling to open the glottis, and the patient puncture part can be lightly pressed by the pressing part.

The invention also discloses a brake management system which comprises the limb brake device and a server, wherein the processing unit of the limb brake device can be in signal connection with the server through the communication unit, and the server can be in signal connection with the medical care terminal so as to realize information interaction.

Detailed Description

The following detailed description refers to the accompanying drawings.

Example 1

After a coronary angiography, the patient is usually required to press the puncture site with a weight such as a sandbag for 6 hours, lying on his/her back for 24 hours, and the limb is braked for 12 hours. During the operation of limb braking, the braking scheme needs to be flexibly adjusted according to the actual physiological state of the patient, and the patient needs to be guided and driven to perform proper activities, so the invention discloses a limb braking device.

Preferably, as shown in fig. 1 to 3, the limb brake device may include: a braking unit 300 for forcibly braking the operative limb of the patient; a monitoring unit 200 for acquiring one or more data information related to the patient; the processing unit 100 is configured to receive the data information sent by the monitoring unit 200 and perform analysis processing to generate a control signal. Preferably, the control signals generated by the processing unit 100 may be sent to the brake unit 300 for adjusting the operating parameters of the brake unit 300 to adapt to the current physical state of the patient. Further, the control signal generated by the processing unit 100 may also be sent to other functional units, where the other functional units may be, for example, the communication unit 500, so that abnormal data information found during monitoring is reported to the corresponding medical staff through the communication unit 500, so that the medical staff can arrive at the site for processing as soon as possible. Since the coronary intervention examination and treatment by femoral artery puncture has the advantages of convenient and quick operation and the like, the method is the most common route for the prior coronary intervention operation, the patient subjected to the coronary intervention examination and treatment by femoral artery puncture is taken as an example for illustration, but the method is not meant to be only suitable for the patient subjected to the coronary intervention examination and treatment by femoral artery puncture, namely, the method can be aimed at all patients subjected to the coronary angiography.

Preferably, as shown in fig. 1, the braking unit 300 may comprise a supporting portion 310 having a substantially flat plate shape, so that a patient can lie on the supporting portion 310, wherein a plurality of interfaces may be arranged on the supporting portion 310 for connecting other components to achieve braking of the limb of the patient, in particular for fixing the operative limb of the patient.

Preferably, as shown in fig. 1, the fixing portion 320 of the brake unit 300 is configured to be capable of being provided on the support portion 310 through the interface in a position-adjustable manner, so that the setting position of the fixing portion 320 can be adjusted according to the physical characteristics of the patient. Further, the fixing portion 320 may be disposed on one side of the patient's limb to fix the patient's limb, wherein the fixing portion 320 may include a first fixing member 321 and a second fixing member 322 disposed at different portions of the patient's limb. Preferably, when the patient's limb is a leg, the first fixing member 321 may be disposed on the thigh portion of the patient's limb, and the second fixing member 322 may be disposed on the calf portion of the patient's limb. Preferably, the fixing portion 320 is capable of determining the setting positions of the first fixing piece 321 and the second fixing piece 322 on the patient's limb in such a manner as to avoid the puncture site, and the puncture site may be pressed for several hours by the pressing portion 330, wherein the pressing portion 330 for pressing the puncture site may be configured as a weight, such as a sandbag or a mechanical structure connected to a transmission mechanism. When the pressing part 330 is configured as a mechanical structure, it can adjust the pressing force applied to the puncture site according to the control signal generated by the processing unit 100, thereby preventing the distal blood supply from being affected by the excessive pressing force or the puncture site from bleeding caused by the excessively small pressing force.

Preferably, as shown in fig. 2, the first fixing member 321 and the second fixing member 322 configured at the fixing portion 320 can be configured as a hollow column structure to be sleeved on the outer side of the patient's limb, wherein hollow areas reserved by the first fixing member 321 and the second fixing member 322 can accommodate corresponding parts of the patient's limb and have at least a part of movable range. Further, as shown in fig. 4, the first fixing element 321 and the second fixing element 322 may be provided with a first substantially annular air bag element 323 on the inner side facing the hollow area, wherein the first air bag element 323 can occupy the movable range by inflation to limit the movement of the patient's limb, thereby realizing the braking function. Preferably, if the first balloon member 323 is over inflated, it may cause the patient's limb to be over-compressed, which may affect the distal blood supply; if the first balloon member 323 is not inflated enough, the operative limb of the patient is not braked effectively, and therefore, the inflation and deflation processes of the first balloon member 323 can be adjusted according to the control signals generated by the processing unit 100.

Preferably, the processing unit 100 may generate the corresponding control signal according to the data information acquired by the monitoring unit 200, wherein the monitoring unit 200 may comprise several monitoring components for acquiring different types of data information.

Preferably, as shown in fig. 4, the monitoring unit 200 may be configured with a monitoring part including a first monitoring part 210 for acquiring distance information, wherein the first monitoring part 210 may be disposed on the first fixture 321 and/or the second fixture 322. Preferably, the first monitoring unit 210 can arrange a plurality of infrared ranging sensors wrapped by the first balloon member 323 on the inner side wall of the first fixing member 321 and/or the second fixing member 322 at circumferential intervals, so as to measure the shortest distance between each sensor and the surface of the first balloon member 323 by using modulated infrared light, so that the processing unit 100 can calculate the perimeter of the surface of the first balloon member 323 according to the shortest distance obtained by each sensor, and the perimeter can represent the local perimeter (i.e. leg circumference or arm circumference) of the operative limb of the patient. Further, the manner in which the processing unit 100 calculates the perimeter of the surface of the first balloon member 323 may be, for example: and determining a plurality of corresponding point positions on the surface of the first air bag member 323 according to the shortest distance acquired by each sensor, connecting the point positions by a relatively smooth curve to form a shape approximately equal to the contour of the leg of the patient, and finally calculating the perimeter of the shape to acquire the leg circumference or the arm circumference. Preferably, when the first monitoring portion 210 obtains the distance information, the processing unit 100 can regulate and control the inflation state of the first air bag member 323, so as to determine the fitting degree of the first air bag member 323 and the operative limb of the patient by making the air pressure value of the first air bag member 323 reach the set threshold value, thereby avoiding measurement deviation caused by different extrusion degrees of the air bag to the operative limb of the patient. Further, the processing unit 100 may determine whether the limb swelling occurs in the portion according to the local circumference of the operative limb of the patient, and may generate a corresponding response scheme or report to a corresponding medical staff using the communication unit 500 when it is determined that the limb swelling occurs.

Preferably, as shown in fig. 5, the monitoring means configured by the monitoring unit 200 may comprise a second monitoring portion 220 for acquiring pressure information, wherein the second monitoring portion 220 may be configured to be located in the area of the patient's heel for acquiring a pressure distribution of the patient's heel, in particular the pressure distribution of the heel on the side of the patient's limb. When a patient's limb is immobilized, it is often difficult to perform a wide range of movements on the foot of the side of the limb, and it is possible to determine whether the degree of braking of the immobilization portion 320 is up to standard by analyzing the pressure distribution of the heel of the side of the limb. Further, when the processing unit 100 determines that the foot of the patient can still perform the activities beyond the set range according to the change of the pressure distribution of the heel on the side of the operative limb of the patient, the braking degree of the fixing portion 320 can be improved by increasing the inflation amount of the first air bag member 323.

Preferably, as shown in fig. 5, the monitoring unit 200 may be configured with a third monitoring part 230 for acquiring image information and/or a fourth monitoring part 240 for acquiring temperature information, wherein the third monitoring part 230 and the fourth monitoring part 240 may acquire data information of the distal end of the operative limb of the patient so as to prevent arterial embolism, insufficient blood supply of the distal end of the limb, and the like. Preferably, when the patient's limb is a leg, the third monitoring part 230 may acquire image information of the foot connected to the patient's limb, so that the processing unit 100 may perform color recognition on the image information of the foot, thereby judging whether the skin color of the patient's foot is abnormal; the fourth monitoring part 240 may acquire temperature information of the foot connected to the operative limb of the patient so that the processing unit 100 may determine whether the temperature of the foot of the patient is abnormal by comparing with a preset temperature threshold. When the patient's limb is immobilized, it can be determined whether the degree of braking of the immobilization portion 320 and/or the degree of compression of the compression portion 330 is excessive by analyzing the skin color and/or temperature of the foot on the side of the patient's limb. Further, when the processing unit 100 judges that the blood supply of the foot of the patient is insufficient according to the skin color and/or temperature of the foot of the side where the operative limb of the patient is located, the normal blood supply of the limb tip can be ensured by reducing the inflation amount of the first balloon member 323 and/or reducing the compression force of the compression portion 330.

Preferably, in general, the fixing portion 320 brakes the patient's limb longer than the compression portion 330 presses the puncture site, and when the compression time reaches a preset time, the compression portion 330 may be removed and the patient's limb may be appropriately moved in a movement-limited manner to prevent thrombosis, wherein the preset time of the compression process may be preferably 6 hours.

Most patients have no clear concept of the movable joints in the event that the limb is braked, and the healthcare staff may not say in detail, resulting in either immobility or tampering with the patient. Preferably, the movement pattern of the patient's limb may include: the muscle tightening exercise to the toe part, the muscle hooking exercise to the instep part and/or the ankle part rotating exercise, wherein the exercise can be alternately completed for a plurality of times so as to achieve the exercise effect. Further, the movement modes of the operative limbs of the patient can be simply referred to as instep extending movement, instep backward bending movement and ankle rotating movement. Preferably, as shown in fig. 5, in order to solve the problem that the patient does not clearly how to perform the proper movement of the operative limb, the limb brake device of the present invention may be further provided with a movable unit 400 for driving the foot of the side of the operative limb of the patient to perform the above-mentioned movement.

Preferably, the movable unit 400 may be provided with a moving part 410 for providing a regulated support force to the patient's foot in the region where the patient's foot is located, wherein the moving part 410 may provide an equal or unequal support force to the patient's foot for adjusting the posture of the patient's foot by regulating the distribution scheme of the support force. Preferably, the movement portion 410 may include a plurality of second balloon members 411 arranged in a specific arrangement, and the foot portion on the side of the patient's limb may be placed on the second balloon members 411, so that the movement portion 410 may adjust the distribution scheme of the supporting force by adjusting the inflation amount of one or more second balloon members 411.

Preferably, the inflation amount of each second air bag member 411 is individually controllable so that each second air bag member 411 may have a respective independent support area, wherein when an object is placed on the support area of any second air bag member 411, the support force applied by the second air bag member 411 may be changed by adjusting the inflation amount thereof so that the object may be pushed up or dropped down; when an object is placed on the support areas of the plurality of second air bag members 411, the distribution scheme of the support force applied by the moving portion 410 can be changed by adjusting the amount of inflation of one or more of the second air bag members 411, so that the object can be adjusted to a designated posture. Further, if the object is a foot on the side of the patient's limb, the foot placed on the movement portion 410 may be supported by the plurality of second air bag members 411, and may perform the action required to complete the designated movement when the inflation amount of one or more of the second air bag members 411 is adjusted. Preferably, when the moving portion 410 is not activated (for example, when the puncture site of the patient is also pressed by the pressing portion 330), each of the second air bag members 411 can form a supporting surface with a substantially equal height by injecting the same amount of air, wherein the amount of air filled in the second air bag member 411 in the initial state can be determined according to the amount of air filled in the first air bag member 323 on the fixing portion 320, so that the height of the second air bag member 411 to raise the foot of the patient can be substantially equivalent to the height of the fixing portion 320 to raise the leg of the patient, thereby ensuring the horizontal placement of the operative limb of the patient to prevent the knee joint of the patient from bending. Further, the second bladder member 411 forms a support surface having an area that is at least larger than the cross-sectional area of a conventional patient's heel to accommodate different patient's feet. Preferably, in order to pursue finer adjustment, the second balloon member 411 of the movement portion 410 may be selected to have as small a size as possible to divide the support area as small as possible, but the second balloon member 411 should be ensured to have sufficient strength at the time of the shape selection to extend the service life of the second balloon member 411 and ensure the safety of the patient.

Preferably, since the movement portion 410 and the second monitoring portion 220 are both disposed in the area where the foot of the patient is located, and the movement portion 410 can be directly contacted with the foot of the patient, the second monitoring portion 220 can be disposed in the movement portion 410 to monitor the pressure applied by the foot of the patient to the surface of the movement portion 410. Preferably, each of the second balloon members 411 of the moving portion 410 may have corresponding coordinate information according to its arrangement position. Further, the second monitoring unit 220 may collect the pressure applied to the surface of each second air bag member 411, so that the processing unit 100 may generate a pressure distribution applied to the surface of the moving unit 410, where the processing unit 100 may determine the specific position and the approximate posture of the foot of the patient according to the pressure distribution obtained by analysis and the corresponding coordinate information. Preferably, the second monitoring part 220 may perform the data collection operation after the second air bag member 411 completes the inflation and deflation operation, so as to avoid data interference.

Preferably, when the processing unit 100 analyzes the pressure distribution on the surface of the moving part 410 according to the data information acquired by the second monitoring part 220, the pressure extreme point can be determined as the heel endpoint of the patient, the heel endpoint of the patient is taken as the coordinate origin, and the coordinate information of each second air bag member 411 is combined to convert the action set required by the patient to complete the designated movement into the inflation and deflation scheme of each second air bag member 411 on the moving part 410, so that the moving part 410 which completes the inflation and deflation operations corresponding to the second air bag members 411 according to the inflation and deflation scheme generated by the processing unit 100 can drive the foot of the patient to make the designated movement, and the designated movement can be completed after continuously or discontinuously completing the plurality of groups of actions.

Preferably, in the process that the motion portion 410 drives the foot of the patient to perform the specified motion, the third monitoring portion 230 may periodically acquire image information of the foot of the patient, so that the processing unit 100 may extract feature points from the foot information of the patient, and determine the posture (i.e. the motion performed) of the foot of the patient according to the extracted feature points, where the feature points extracted by the processing unit 100 may be bone points of the foot of the patient. Preferably, the skeletal points of the foot of the patient may include a foot bone point and an ankle bone point, the foot bone point being a tarsal bone point, a metatarsal bone point and a phalangeal bone point, wherein the tarsal bone point may include a calcaneal bone point, the metatarsal bone point may include a first metatarsal bone point and a fifth metatarsal bone point, and the phalangeal bone point may include a first phalangeal bone point and a fifth phalangeal bone point. Further, the tarsal bone sites may include one or more of talus sites, medial cuneiform sites, cuboid sites, and navicular sites. Further, when the phalanges point positions are selected, one or more point positions can be selected from the distal phalanges, the middle phalanges and the proximal phalanges, in other words, the first phalanges point positions included in the phalanges point positions can be one or more of the first distal phalanges point positions, the first middle phalanges point positions and the first proximal phalanges point positions; the fifth phalangeal point included in the phalangeal point may be one or more of a fifth distal phalangeal point, a fifth medial phalangeal point, and a fifth proximal phalangeal point. It should be noted that, the above points are all points selected on corresponding bones of the foot and ankle, and the names of the bones of the foot and ankle correspond to common knowledge, for example, the first phalange is the big toe and the fifth phalange is the small toe. By connecting the above basic foot and ankle points, an image for representing the posture of the foot of the patient can be obtained, and when more foot and ankle points are added, a more accurate foot posture can be obtained, but the calculation load of the processing unit 100 is also increased, and the adaptability adjustment can be performed according to the performance of the software and hardware configured by the processing unit 100.

Preferably, the data information sent to the processing unit 100 by each monitoring component of the monitoring unit 200 may be accompanied by time information of the sampling node, so that the processing unit 100 may use the time information to order when performing analysis processing on the data information. Further, when determining the posture of the foot of the current patient according to the image information acquired by the third monitoring portion 230, the processing unit 100 may call the inflation amount of each second air bag member 411 of the movement portion 410 under the current time node to determine whether the posture of the foot of the current patient matches the distribution scheme of the supporting force applied by the movement portion 410 in a model simulation manner. If the two are not matched, the data information of at least one sampling node can be obtained again by reducing the sampling interval of the third monitoring part 230 so as to perform data verification, wherein if the data verification result is not matched, the movement is stopped and the medical staff is informed to check the data through the communication unit 500; if the data verification result is matched, continuing the exercise and temporarily storing the abnormal data in the processing unit 100, and reporting the abnormal data to the medical staff together with the exercise effect evaluation result after the exercise is finished. Further, when the amount of abnormal data stored in the processing unit 100 during one movement period exceeds a set threshold, the movement may be stopped immediately and the medical staff is informed to check through the communication unit 500.

Preferably, the patient can activate the calf muscle group after completing the designated exercise and the blood circulation is smooth, which is shown that the foot of the patient will become pink, so after the exercise portion 410 drives the foot of the patient to complete the designated exercise, the fourth monitoring portion 240 can acquire the current temperature information of the foot of the patient, so that the processing unit 100 can analyze the blood flow condition of the foot of the patient after completing the designated exercise according to the temperature information acquired by the fourth monitoring portion 240, and further evaluate the effect of the exercise, wherein the fourth monitoring portion 240 can acquire corresponding data information by means of optical detection and the like. Preferably, the exercise effect evaluation result obtained by the analysis of the processing unit 100 can be reported to the medical staff via the communication unit 500, so that the medical staff can timely grasp the actual state of the patient's limb after the appropriate exercise, thereby facilitating the adjustment of the braking scheme.

Preferably, the limb braking device can also be used alone to guide and drive the patient to perform ankle pump movements to promote patient lower limb blood circulation and lymphatic return without the need for operative limb braking, and can also improve the utilization of the limb braking device.

Preferably, after a preset compression time is reached, the compression portion 330 is removable from the patient puncture site, but the compression portion 330 is still capable of being in a ready state, such that it can be switched to an operating state at a specific period of time, wherein the ready state is that it is not in contact with the patient puncture site but is capable of pressing the puncture site at a first time, and the operating state is that it is in contact with the patient puncture site and applies a force of a preset force to the puncture site. Further, the pressing portion 330, which is already in a ready state, should have a force applied to it preset to "light pressure" by the processing unit 100 when it is switched to an operating state, so that a specific time is smoothly spent. Preferably, the special period may be a period of time from a time node at which the special event is triggered to a time node at which the special event is completed, wherein the special event may be, for example, a cough. Since the physical vibration caused by the cough may cause local impact, particularly for the puncture site, the wound of the site is more susceptible to the impact caused by the cough, and thus the compression part 330 is used to temporarily slightly press the puncture site before the patient completes the cough movement, so as to reduce the impact on the wound.

Preferably, when coughing is taken as a special event, it is manifested by first inhaling, closing the glottis, contracting the respiratory muscles, increasing the internal pulmonary pressure, then opening the glottis, and finally injecting air into the lungs, usually accompanied by sound, wherein forced exhalation against the closed glottis can effect opening of the glottis. Further, the local impact generated by the cough usually occurs at the stage when the last air is ejected from the lungs, because a large amount of air is rapidly released from the lungs at this stage, so that the patient's body is unconsciously shaken and is likely to impact on the wound, and thus the impact on the wound by the cough can be reduced by detecting the cough and switching the pressing part 330 to the working state before the air in the lungs is rapidly released.

Preferably, the patient-related data information may be utilized to detect whether the patient is performing a cough event, wherein the patient-related data information may be acquired by a non-invasive wearable device. Preferably, a photoplethysmography (PPG) sensor can be configured on the wearable device to obtain changes in the patient's blood volume through non-invasive optical techniques to enable detection of cough movements. In particular, the photoplethysmograph sensor may utilize one or more light emitting diodes and one or more photodetectors to acquire light reflected by blood and tissue, wherein the detection principle is: the oxygenated blood will absorb the emitted light at a different rate than the skin, muscle tissue, bone, etc., so that fluctuations in the amount of light acquired by the photodetector can characterize the change in blood volume. Preferably, an acceleration sensor can be configured on the wearable device for calibrating the data acquired by the photoplethysmograph sensor. Preferably, when the data information acquired by the photoplethysmograph sensor is suddenly dropped, especially when the data information acquired by the acceleration sensor is disturbed, the wearable device may send a signal accompanied with the cough intention to the processing unit 100 through the communication unit 500, so that the processing unit 100 may drive the pressing part 330 to immediately switch to the working state.

This is because when the patient has a cough intention, the patient exhales hard against the closed glottis, which can cause a sudden increase in the circulating blood pressure, and this phenomenon can be expressed as a sudden drop in the acquired data information of the blood volume in the detection of the photoplethysmography sensor, and therefore, the sudden drop in the acquired data information of the photoplethysmography sensor is used as an early warning signal representing the cough intention, so that countermeasures can be taken in advance. Further, the patient is in a state of limited movement during braking, and in most cases lies down, lies down and rests, the data information acquired by the acceleration sensor is relatively stable, but when the data information acquired by the photoplethysmography sensor is suddenly reduced and the data information acquired by the acceleration sensor is disturbed, the patient can be further verified to be performing a cough action of forcefully exhaling to open the glottis, and the compression part 330 can be utilized to lightly press the puncture part of the patient. Preferably, the cough intention is to have a tendency to complete a complete cough motion, wherein it is possible in the present invention to judge whether the patient has a cough intention by detecting a part of the cough motion being performed, and to drive the pressing part 330 to complete the state switching when it is determined that the patient has a cough intention, even if the patient's cough intention is suspended or interrupted in a subsequent process. Further, the patient may exhibit a relaxed state after the patient's cough intent is discontinued or interrupted in a subsequent process.
