Abstract
The utility model provides a pressure -sensitive device of syringe, including outer box, flush fluid passageway, response diaphragm, the flush fluid passageway be located the both ends coupling hose of outer box, flush fluid passageway, outer box go up to open and have the pressure mouth, the pressure mouth is located the top of flush fluid passageway, response diaphragm card go into outer box and lie in the pressure mouth. The utility model has the advantages of reasonable design, what the response diaphragm passed through that the sensor can be accurate gives the pressurization instrument with hose pressure transmission to at any time, control the flow of washing liquid.
Description
Technical field
This utility model relates to a kind of pressure sensitive device of syringe, belongs to technical field of medical instruments.
Background technology
In human body minimally invasive medical procedures, need to be exclusively used in the syringe rinsing residual liquid in human body, syringe is application rotary pressing instrument, the pressure hose of syringe is inserted in the rotation disc of pressurization instrument, rotation disc is wriggled flexible pipe in rotation, make pressure hose produce extruding and be transported in human body by flushing liquor and rinse, but pressurization instrument can produce pressure in wriggling pressure hose squeezing flushing liquor, pressure is crossed conference and is caused flushing liquor input flow rate too drastic, directly affects in human body and rinses true effect.The syringe of prior art does not have pressure sensitive device, is the screen visual field by endoscope, sees the flow of flushing liquor clearly in operation, the rotary speed of regulating rotating type pressurization instrument rotation disc again, control the flow of flushing liquor, operation trouble, can not meet desirable surgical effect.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned deficiency existing in prior art, and provide a kind of reasonable in design, the pressure sensitive device of the syringe of energy Real-Time Monitoring hose pressure.
This utility model solves the problems of the technologies described above adopted technical scheme: a kind of pressure sensitive device of syringe, it is characterized in that: it comprises outer box, passage of irrigation fluid, reaction diaphragm, described passage of irrigation fluid is positioned at outer box, the two ends connecting hose of passage of irrigation fluid; Described outer box has pressure port, and pressure port is positioned at the top of passage of irrigation fluid; Described reaction diaphragm snaps in outer box and is positioned in pressure port.
Reaction diaphragm described in the utility model is provided with collar, outer box is provided with draw-in groove, collar snaps in draw-in groove internal fixtion.
The edge of reaction diaphragm described in the utility model is provided with hasp, and outer box is provided with groove, and hasp snaps in groove.The design of hasp, is convenient to strike out reaction diaphragm with the hand.
The two ends of passage of irrigation fluid described in the utility model are provided with hose connection seat, for Bonding pressure flexible pipe.
This utility model compared with prior art, has following positive effect: reasonable in design, and hose pressure can accurately be passed to pressurization instrument by sensor by reaction diaphragm, to control the flow of cleanout fluid at any time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is detonation configuration schematic diagram of the present utility model.
Fig. 3 is the sectional structure schematic diagram of reaction diaphragm in this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail.
Embodiment:
See Fig. 1 ~ Fig. 3, the present embodiment comprises outer box 1, passage of irrigation fluid 2, reaction diaphragm 9, and described passage of irrigation fluid 2 is positioned at outer box 1, the two ends connecting hose 7 of passage of irrigation fluid 2; Described outer box 1 has pressure port 4, and pressure port 4 is positioned at the top of passage of irrigation fluid 2; Described reaction diaphragm 9 snaps in outer box 1 and is positioned in pressure port 4.
In the present embodiment, reaction diaphragm 9 is provided with collar 10, outer box 1 is provided with draw-in groove 5, collar 10 snaps in draw-in groove 5 internal fixtion.
In the present embodiment, the edge of reaction diaphragm 9 is provided with hasp 11, and outer box 1 is provided with groove 12, and hasp 11 snaps in groove 12.The design of hasp 11, is convenient to strike out reaction diaphragm 9 with the hand.
In the present embodiment, the two ends of passage of irrigation fluid 2 are provided with hose connection seat 3, for Bonding pressure flexible pipe 7.
The present embodiment is arranged on the flexible pipe 7 of syringe, and syringe is mounted on rotary pressing instrument, and pressure hose 7 is inserted in the rotation disc of rotary pressing instrument, and reaction diaphragm 9 is connected with the sensor of pressurization instrument; Realize the rotary speed of the program control adjustment rotation disc of rotary pressing instrument, ensure syringe cleanout fluid stability of flow.
During use, the rotation disc of rotary pressing instrument is in rotary course, extruding wriggling pressure hose 7, flushing liquor enters in injector delivery to human body and carries out rinsing and producing pressure, if reaction diaphragm 9 is subject to excessive pressure from pressure port 4, will be protruding in the middle of reaction diaphragm 9, and by sensor, information excessive for pressure is sent to rotary pressing instrumentation control system, control system regulates rotation disc rotary speed, make the flow of flushing liquor in flexible pipe 7 reach optimum state, ensure carrying out smoothly of operation.
In addition, it should be noted that, the specific embodiment described in this description, as long as the undeclared concrete shape of its part and size, then this part can for any shape and size adapted with its structure; Meanwhile, the title that part is got also can be different.All equivalences of doing according to structure, feature and the principle described in this utility model inventional idea or simple change, be included in the protection domain of this utility model patent.
