Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
The present invention provides a kind of new medical pinch valve, by the flexible rubber dissepiment arranged in the pinch valve,
Valve utilizes the gradual change tension force produced when the elasticity of diaphragm of rubber and deformation during opening and closing, slow down the hard hit of valve seat, from
And 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
Cavity 9 of the end with opening, is provided with liner 5, the liner 5 in the valve body 1 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.
Liner of the present invention 5 is preferably two madial walls for being distributed in valve body 1, convenient placement and fixation to diaphragm 2；Cavity 9
For placing to adopting blood transfusion rubber tube 3.The present invention is provided with barrier film 2, and the two ends of barrier film 2 between cavity 9 and push rod 4
It is fixed between liner 5 and the madial wall of valve body 1, the two ends of diaphragm 2 are threaded connection and are pressed abd fixed on the valve body 1 of liner 5
Between, so can ensure that the firm and sealing of diaphragm 2.
Gradual change tension force after in order to ensure the compression and compression during the promotion pressure of 2 drawn stem of diaphragm 4, slows down push rod
4 preferably have the flexible rubber dissepiment of elastic module with the hard hit of valve body 1, the diaphragm 2.The present invention is to concrete barrier film 2
Shape and material be not particularly limited, as long as resilient softwood matter (particularly whippy quality of rubber materials), can be real
Existing the object of the invention slows down the collision between push rod 4 and valve body 1, reduces the form of barrier film 2 of noise level.
Further, in order to realize movement of the push rod 4 to diaphragm 2, the push rod 4 is preferably into middle concrete raised T-shaped.
And the push rod 4 is vertical with liner 5, the T-shaped two ends still more preferably for push rod 4 are 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 the 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 liner 5 adopts end angle with the junction of the madial wall of valve body 1, cylinder 7
Surface seal structure 8, as shown in figure 4, further, in the end edged surface sealing structure O-ring is provided with, by pressing with cylinder 7
Consolidation is now sealed.
Medical diaphragm type pinch valve concrete operating principle of the present invention and process are：Blood transfusion rubber tube 3 will be adopted to be open from cavity 9
It is put in cavity 9, when needing to block blood circulation, cylinder 7 is inflated, compressed gas are full of in liner 5, promotes push rod
4 move upwards, while so that barrier film 2 deforms, push rod 4 is continued up to deforming to adopting blood transfusion rubber tube 3, is cut
Disconnected blood passes through；In the process due to the elasticity and distorting tension of barrier film 2, push rod 4 and the hard hit of valve body 1, drop are slow down
Low noise level.When blood circulation is needed, cylinder 7 is deflated, compressed gas are gradually discharged in liner 5, push rod 4 is subject to
Reduced pressure, 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 to transport downwards
Dynamic, while adopting blood transfusion rubber tube 3 recovers shape, blood circulates again, and the deformation of barrier film 2 in the process gradually recovers, effect
Power on push rod 4 is gradually reduced, and slow down push rod 4 and the hard hit of cylinder 7, reduces noise level.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
