Background technique
Currently, patient in hospital when using tracheal catheter, since the cuff pressure at tracheal catheter does not have adjustment criteria, covers The pressure of Nang Chu is less than or equal to the airway pressure in tracheal catheter, then meeting gas leakage at tracheae, it is difficult to realize gas supply effect, for this purpose, Most hospital can all increase the pressure at cuff, the airway pressure being larger than in tracheal catheter in actual operation, but work as cuff When pressure is excessive greater than the airway pressure in tracheal catheter, then cuff expansion is excessive, causes to squeeze to person's windpipe inner wall, Jin Eryin Complication is sent out, the ratio that Hospitals at Present patient causes complication because inner surface of trachea is extruded in turn is very big, makes to the health of patient At extreme influence.
Summary of the invention
The purpose of this utility model is that: a kind of cuff for endotracheal catheter pressure monitoring and control system are provided, it is existing to solve The problem of having the use of tracheal catheter air bag often will lead to complication for patients, causes extreme influence to the health of patient.
To solve the above problems, such a cuff for endotracheal catheter pressure monitoring of proposed adoption and control system, including tracheae Conduit, anesthesia respirator, connecting tube and control unit, connecting tube are Y-shaped pipe, one end of tracheal catheter and anesthesia respirator Air inlet and air outlet be connected respectively with three ports of connecting tube, cuff is arranged on tracheal catheter, further include have it is electronic It is evacuated inflating pump and control unit, is connected between air bag and electric air exhaust inflating pump by inflated hose, tracheal catheter, connecting tube Or it is fixedly installed gas pressure sensor in the chamber being connected with tracheal catheter or connecting tube, cover intracapsular or is connected with cuff Also be fixedly installed gas pressure sensor in logical chamber, the gas pressure sensor and electric air exhaust inflating pump respectively with Control unit is electrically connected.
It further include having control panel in aforementioned monitoring and control system, electric air exhaust inflating pump and control unit are fixed It is set in control panel, the first air pressure sensing chamber and the second air pressure sensing chamber, the gas pressure is further fixed in control panel Force snesor totally two, and to be fixedly installed on two air pressures detection respectively indoor for described two gas pressure sensors, cuff with Tee tube is additionally provided between electric air exhaust inflating pump, the cuff is connected to by inflated hose with one end of tee tube, threeway The other both ends of pipe are connected with the first air pressure sensing chamber and electric air exhaust inflating pump respectively, the second air pressure sensing chamber by hose with Connecting tube is connected;
Display and adjusting panel are provided on control panel, display and adjusting panel, which are set, is fixed on control panel Front, and display and adjusting panel are also connected with control unit respectively.
Compared with prior art, the utility model enable to cover intracapsular air pressure according to the pressure change in tracheal catheter and Variation, and remains slightly larger than the air pressure in tracheal catheter, thus guarantee at cuff when in use will not gas leakage, ensure respiration The using effect of machine, meanwhile, covering intracapsular air pressure can be always with the variation of air pressure in tracheal catheter by the control of control unit And dynamic adjusts, and is not above that air pressure in tracheal catheter is excessive, and cuff remains the compressing of patient airway's inner wall In a lesser amplitude, the intelligentized control method of cuff pressure is realized, and then avoid causing complication.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the control principle drawing of the utility model.
Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type is described in further detail, it should be understood that specific embodiment described herein is only to explain the utility model, not For limiting the utility model.
Embodiment:
(in Fig. 1, appended drawing reference 17 indicates tracheae, and 18 indicate lung) referring to Figures 1 and 2, the present embodiment provides a kind of gas System, including tracheal catheter 1, anesthesia respirator, connecting tube 4 and control unit 5, connection is monitored and controlled in pipe conduit cuff pressure Pipe 4 is three of Y-shaped pipe, one end of tracheal catheter 1 and the air inlet 2 of anesthesia respirator and gas outlet 3 respectively with connecting tube 4 A port be connected, cuff 6 is arranged on tracheal catheter 1, further includes having electric air exhaust inflating pump 9 and control unit 13, air bag 6 with It is connected between electric air exhaust inflating pump 9 by inflated hose 10, is connected in the chamber being connected with connecting tube 4 and with cuff 6 Gas pressure sensor 12, the gas pressure sensor 12 and electric air exhaust inflating pump are fixedly installed in logical chamber respectively 9 are electrically connected with control unit 5 respectively.
Electric air exhaust inflating pump 9 and control unit 5 are fixedly installed in control panel 13, also fixed in control panel 13 There are a first air pressure sensing chamber 7 and the second air pressure sensing chamber 8, the gas pressure sensor 12 totally two, and described two gases Pressure sensor 12 is fixedly installed on two air pressure detection interiors respectively, is additionally provided between cuff 6 and electric air exhaust inflating pump 9 Tee tube 11, the cuff 6 are connected to by inflated hose 10 with one end of tee tube 11, the other both ends of tee tube 11 respectively with First air pressure sensing chamber 7 is connected with electric air exhaust inflating pump 9, and the second air pressure sensing chamber 8 is connected by hose 14 with connecting tube 4 It is logical, display 15 and adjusting panel 16 are provided on control panel 13, display 15 and adjusting panel 16, which are set, is fixed on control The front of panel 13, and display 15 and adjusting panel 16 are also connected with control unit 13 respectively.
The control system detects the air pressure in cuff 6 and tracheal catheter 1 by gas pressure sensor 12 respectively, and by gas Pressure signal is transferred to control unit 5, and the air pressure in cuff 6 is adjusted by electric air exhaust inflating pump 9, when air pressure is less than in cuff 6 Equal to when air pressure, control unit 5 receives air pressure signal and controls electric air exhaust inflating pump 9 and beats into cuff 6 in tracheal catheter 1 Gas, until the control of control unit 5 closes electric air exhaust and inflates after air pressure adds N megapascal equal to air pressure in tracheal catheter 1 in cuff 6 Pump 9 is to stop inflating into cuff 6;When air pressure adds N megapascal greater than air pressure in tracheal catheter 1 in cuff 6, control unit 5 is controlled Electric air exhaust inflating pump 9 processed is evacuated out of cuff 6, to reduce air pressure in cuff 6, when air pressure is greater than in tracheal catheter 1 in cuff 6 Air pressure, and be less than or equal to air pressure in tracheal catheter 1 when adding N megapascal, electric air exhaust inflating pump 9 is closed in the control of control unit 5, thus So that air pressure is consistently greater than air pressure in tracheal catheter 1 in cuff 6, and is less than or equal to air pressure in tracheal catheter 1 and adds N megapascal, avoid Prevent cuff 6 excessive to the pressure of inner surface of trachea while gas leakage, avoid causing complication, realize that intelligence is adjusted, N 1,2,3, 4 or 5, N value size are adjusted by adjusting panel 16, and the hardware device provided by the system simultaneously utilizes existing programming technique It can be realized, this patent only protects hardware components.
