Description

Intelligent bladder irrigation system and matched pipeline

Technical Field

The invention relates to an intelligent bladder irrigation system and a matched pipeline, belonging to medical instruments used by medical institutions.

Background

Bladder irrigation (bladder irrigation) is a clinical method that an irrigation pipeline is communicated with a catheter, an irrigation liquid or a liquid medicine for treatment is filled into the bladder, and the filled liquid is drained out by using a siphon principle. The main clinical purpose is to eliminate blood clots, mucus, bacteria and other foreign matters in the bladder by flushing or to treat some bladder diseases, such as cystitis and bladder tumor, by infusing medicine. The prior operation method is that a disposable bladder irrigator or an infusion apparatus is adopted to be communicated with an infusion bag or an irrigation liquid container, a medicine is infused into the bladder through an irrigation cavity of a three-cavity catheter which is kept in a patient body, and then the liquid is discharged into a urine collecting bag through a drainage cavity of the three-cavity catheter. Existing bladder irrigation techniques also suffer from a number of common deficiencies, including but not limited to: (1) the inlet/outlet amount and the flushing speed of the flushing liquid highly depend on manual metering and control, and the nursing labor intensity is high; (2) the temperature of the irrigation solution is not controlled, and the irrigation solution with lower temperature continuously enters the bladder in large quantity, which causes bladder spasm or cold cicada of the patient, and the compliance of the patient is poor. (3) The color of the liquid drained after flushing is a main observation index for judging the internal hemorrhage of the bladder or the termination of flushing (liquid clarification), the prior art highly depends on manual identification, and the standardized method is that an international PANTONE color chart (PANTONE) is adopted as a standard color chart to be compared with the drainage liquid through manual visual inspection, so that the result subjectivity is high, and the time is consumed for 5-8 minutes each time, and the nursing efficiency is influenced. Therefore, a bladder irrigation system with higher intelligence degree is needed to meet the developing clinical requirements.

Disclosure of Invention

The invention provides an intelligent bladder irrigation system and a matched pipeline, which mainly comprise a control mainboard, a flow sensor, a flow control device, a color recognition sensor, a heating module, a communication module, a human-computer interaction interface and a matched pipeline, wherein the control mainboard comprises:

the control mainboard is an integrated circuit which is constructed by taking a core processor, a memory, a signal processor and the like as main bodies, wherein the core processor comprises a single chip Microcomputer (MCU), a CPU and the like; embedded software is also arranged in the control mainboard and is burnt in the memory; the control main board is used for completing data processing, executing instructions, exchanging information with the logic component and the like.

The flow sensor is used for monitoring the flow or the flow speed of liquid in the flushing pipeline and is communicated with the core processor. Flow sensors include, but are not limited to, infrared drop sensors, ultrasonic flow sensors, electromagnetic flow meters. For example, an infrared liquid drop sensor is adopted, a Murphy dropping funnel is arranged in a flushing pipeline, the infrared liquid drop sensor is horizontally arranged on the periphery of the flushing pipeline, when liquid drops fall down and pass between a transmitting tube and a receiving tube of the infrared liquid drop sensor, an electric signal of the infrared liquid drop sensor changes, and the flow speed and the flow of the liquid are calculated through signal amplification, AD conversion and conversion of the product of the number of drops and the volume of a core processor. For another example, an ultrasonic flow sensor is arranged on the periphery of the flushing pipeline, and the flow speed and the flow of the flushing liquid are dynamically calculated when the flushing liquid flows through the flushing pipeline.

The flow control device is used for controlling the flushing amount and the flushing speed, and is communicated with the core processor to work. For example, the mode of controlling the periphery of the flushing pipeline is adopted, the flow control device adopts a motor to drive a throttling device (such as a worm gear, a roller and the like) to extrude the flushing pipeline, so that the size of the inner path of the flushing pipeline is changed, and the adjustment of the flushing flow is realized. After the periphery of the flushing pipeline is limited in the flow control device, the flow and the flow rate of flushing liquid can be controlled by adjusting the size of an internal passage of the flushing pipeline, and meanwhile, the opening or closing of the pipeline can be controlled, so that quantitative flushing or timing flushing is realized.

The color identification sensor is used for dynamically identifying the color of liquid flowing out of the bladder in the flushing process, and is communicated with the core processor to work. The color recognition sensor is arranged on the periphery of the flushing pipeline, and the flushing pipeline at the position of the color recognition sensor is colorless and transparent. The color recognition sensor dynamically monitors the color of the drainage liquid, compares the acquired information with color parameters built in the embedded software, and gives a color comparison result, and when the drainage liquid is abnormal in color or colorless and transparent, gives prompt information. For example, the drainage fluid shows the blood color to prompt the patient to continuously bleed in the bladder, or the blood color of the drainage fluid becomes dark to prompt the increase of the amount of the bleeding in the bladder; when the drainage liquid is kept in a colorless and clear state, the completion of the flushing work is prompted. The standard color parameters built in the embedded software adopt 6-9 different color levels, and different color levels adopt different color numbers to express the blood content in the drainage fluid. For example, a PANTONE color card (PANTONE) is adopted as a standard color built in the embedded software, the color comparison result is prompted by the color number of the PANTONE color card, and if the color number is 1807C, the blood content in the drainage fluid is 7.5% -8.5%; color number 656C, which indicates a blood content of 0 in the drainage fluid, can end the wash.

The heating module is not limited to heating the washing liquid, for example, the heating module can be arranged on the outer wall of the washing liquid container, and the heating module heats the washing liquid integrally; or the heating module is arranged at the periphery of the flushing pipeline and is used for locally heating the flushing liquid flowing through the position.

The communication module is used for transmitting or outputting monitoring information and communicated with the core processor for working. The monitoring information sent or output by the communication module comprises the temperature of the flushing liquid, the starting and stopping time of flushing, the flushing duration, the flushing speed, the temperature of the flushing liquid, the flushing amount input and the flushing amount output in unit time.
