Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
The utility model provides a kind of new medical pinch valve, by the elastic caoutchouc that is set in the pinch valve every
Film, the gradual change tension force produced when during valve is opened and closed using elasticity and the deformation of diaphragm of rubber, slows down acutely hitting for valve seat
Hit, so as to reduce noise level.
A kind of new medical diaphragm type pinch valve, as shown in Figures 1 and 2, including valve body 1, the top of the valve body 1 is one
It is provided with cavity 9 of the end with opening, the valve body 1 in liner 5, the liner 5 and is provided with push rod 4 and cylinder 7, the folder
Pipe valve also includes barrier film 2, and the barrier film 2 is located between cavity 9 and push rod 4, and the two ends of the barrier film 2 are fixed on liner 5 and valve
Between the madial wall of body 1.
The utility model liner 5 is preferably two madial walls for being distributed in valve body 1, convenient placement and fixation to diaphragm 2；Chamber
Body 9 is used for placing to adopting blood transfusion rubber tube 3.The utility model is provided with barrier film 2, and barrier film between cavity 9 and push rod 4
2 two ends are fixed between liner 5 and the madial wall of valve body 1, and the two ends of diaphragm 2 are connected through a screw thread and are pressed abd fixed on liner 5
Valve body 1 between, can so ensure the firm and sealing of diaphragm 2.
In order to ensure the gradual change tension force after the compression and compression during the drawn stem 4 of diaphragm 2 promotion pressure, slow down push rod
4 be preferably the flexible rubber dissepiment of flexible variable with the hard hit of valve body 1, the diaphragm 2.The utility model to specifically every
The shape and material of film 2 are not particularly limited, as long as flexible softwood matter (the particularly quality of rubber materials of high resilience), energy
Realize that the utility model purpose slows down the collision between push rod 4 and valve body 1, reduce the form of barrier film 2 of noise level.
Further, it is preferably middle specific raised T-shaped by the push rod 4 in order to realize movement of the push rod 4 to diaphragm 2.
It is still more preferably vertical with liner 5 for the T-shaped two ends of push rod 4 and the push rod 4 is vertical with liner 5.Meanwhile, in order to improve
The sealing of push rod 4, the push rod 4 is provided with sealing ring 6 with the perpendicular joints of liner 5, is still more preferably graphite grazing
Circle.
Further, the madial wall of valve body 1 is provided with water wave line with the junction of barrier film 2, as shown in figure 3, the setting of waterline
The sealing that valve body 1 is connected with barrier film 2 can be improved.The junction of the liner 5 and the madial wall of valve body 1, cylinder 7 uses end angle
Surface seal structure 8, as shown in figure 4, further, O-ring is provided with the end edged surface sealing structure, by being pressed with cylinder 7
Consolidation is now sealed.
The utility model medical diaphragm type pinch valve concrete operating principle and process are：Blood transfusion rubber tube 3 will be adopted from cavity 9
Opening is put into cavity 9, and when needing to block blood circulation, cylinder 7 is inflated, and compressed gas is full of in liner 5, is promoted
Push rod 4 is moved upwards, while so that barrier film 2 deforms, and push rod 4 is continued up to becoming to adopting blood transfusion rubber tube 3
Shape, blocks blood and passes through；In the process due to the elasticity and distorting tension of barrier film 2, it slow down push rod 4 and acutely hit with valve body 1
Hit, reduce noise level.When needing blood circulation, cylinder 7 is deflated, compressed gas is gradually discharged in liner 5, push rod
The 4 pressure reductions being subject to, barrier film 2 produces tension force due to recover its original-shape, and the tension force effect of barrier film 2 promotes push rod 4
Move downward, while adopting blood transfusion rubber tube 3 recovers shape, blood circulates again, and the deformation of barrier film 2 is gradually extensive in the process
Multiple, the power acted on push rod 4 is gradually reduced, and be slow down push rod 4 and the hard hit of cylinder 7, is reduced noise level.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
