Further, the free end of the present invention's fixed arm wherein is also provided with protuberance, and in the time that liquid stopping clamp is closed, the free end of described elastic arm is fastened under described protuberance.
Priority scheme of the present invention is: described body, fixed arm and elastic arm are one-body molded.
The present invention is due to the utilization of above-mentioned technology, compared with prior art there is following good result: the free end of fixed arm wherein and the free end of elastic arm are under clamping state, described the first noumenon tight lock part and the first elastic arm tight lock part, described body extruding discharge opeing portion and elastic arm extruding discharge opeing portion, described the second body tight lock part and the second elastic arm tight lock part are against arranging with clamping woven hose, liquid in woven hose can not be flowed, simultaneously, body extruding discharge opeing portion and elastic arm push the mutual extruding woven hose of discharge opeing portion and produce transfusion malleation, guarantee that the liquid in woven hose pushes ahead, can prevent that blood backflow from stopping up venous detaining needle or entry needle syringe needle with blood in woven hose, thereby avoid forming thrombus.
Four, brief description of the drawings
Fig. 1, be according to the present invention propose structural representation;
Fig. 2, be the schematic diagram that the present invention coordinates with woven hose.
Five, detailed description of the invention
Below in conjunction with drawings and Examples, structure of the present invention is further described:
Mark in figure: 1, body; 2, fixed arm; 3, elastic arm; A1, the first noumenon tight lock part; A2, the first elastic arm tight lock part; B1, body extruding discharge opeing portion; B2, elastic arm extruding discharge opeing portion; C1, the second body tight lock part; C2, the second elastic arm tight lock part; D, woven hose fixing hole; E, woven hose; K, protuberance.
In the drawings, liquid stopping clamp of the present invention comprises body 1, and a side of described body 1 is provided with fixed arm 2, and opposite side is provided with elastic arm 3. On described fixed arm 2 and elastic arm 3, be equipped with the woven hose fixing hole D that allows that woven hose E passes. In the time that use is of the present invention, the woven hose fixing hole D of woven hose E from described fixed arm 2 and elastic arm 3 passes. The clamping in the time that liquid stopping clamp is closed of the free end of the free end of described fixed arm 2 and elastic arm 3; The free end of described fixed arm 2 is also provided with protuberance K, and in the time that liquid stopping clamp is closed, the free end of described elastic arm 3 is fastened under described protuberance K.
Described body 1 is provided with the first noumenon tight lock part A1, and the corresponding the first noumenon tight lock part of described elastic arm 3 A1 is provided with the first elastic arm tight lock part A2; On described body 1, be also provided with the body extruding B1 of discharge opeing portion in the first noumenon tight lock part A1 connection, the corresponding body extruding of described elastic arm 3 B1 of discharge opeing portion is provided with the elastic arm extruding B2 of discharge opeing portion.
The described body extruding B1 of discharge opeing portion mono-side is also provided with the second body tight lock part C1, and described elastic arm 3 is provided with the second elastic arm tight lock part C2 corresponding to the second body tight lock part C1.
The present invention is under the state of opening liquid stopping clamp, be that the free end of described fixed arm 2 and the free end of elastic arm 3 do not have clamping, described the first noumenon tight lock part A1 and the first elastic arm tight lock part A2, the described body extruding B1 of discharge opeing portion and the elastic arm extruding B2 of discharge opeing portion, described the second body tight lock part C1 and the second elastic arm tight lock part C2 do not push woven hose E, like this, the liquid in woven hose E can freely flow in woven hose E. when the present invention is closing under the state of liquid stopping clamp, be that the free end of described fixed arm 2 and the free end of elastic arm 3 are under clamping state, described the first noumenon tight lock part A1 and the first elastic arm tight lock part A2, the described body extruding B1 of discharge opeing portion and the elastic arm extruding B2 of discharge opeing portion, described the second body tight lock part C1 and the second elastic arm tight lock part C2 are against arranging and clamp continuously woven hose E, at this moment, liquid in woven hose E can not flow from a side direction opposite side of clamping point, and, the described body extruding B1 of discharge opeing portion and the elastic arm extruding B2 of discharge opeing portion mutually push woven hose E and produce a transfusion malleation, liquid in woven hose E is pushed ahead, can prevent that blood backflow from stopping up venous detaining needle or entry needle syringe needle with blood in woven hose E, thereby avoid forming thrombus.
Why the present invention is also provided with the body extruding B1 of discharge opeing portion in the first noumenon tight lock part A1 connection, the corresponding body extruding of described elastic arm 2 B1 of discharge opeing portion is provided with the elastic arm extruding B2 of discharge opeing portion, when the present invention is under the state of closing liquid stopping clamp, strengthen clamping woven hose E, by the fluid balance extruding in woven hose E, make effectively to produce a transfusion malleation between the clamping point of described woven hose E and human transfusion part.
Why the present invention is also provided with the second body tight lock part C1 in the described elastic arm extruding B1 of discharge opeing portion mono-side, be provided with the second elastic arm tight lock part C2 at described elastic arm 3 corresponding to the second body tight lock part C1, this mutually pushes woven hose E and produces transfusion malleation except it, or to the first noumenon tight lock part A1 and the first elastic arm tight lock part A2, the further raising of the body extruding B1 of discharge opeing portion and the elastic arm extruding B2 of discharge opeing portion extruding woven hose E reliability: this is because the second body tight lock part C1 and the second elastic arm tight lock part C2 also clamp woven hose E simultaneously, even if be returned to after the free end of elastic arm 3 is pressed under the free-ended protuberance K of fixed arm 2, liquid in woven hose E also cannot flow backwards again, from and many one heavy technical measures effectively guarantee the generation of woven hose E transfusion malleation, avoid occurring the phenomenon of any negative pressure.
Application the present invention, can make woven hose E realize transfusion malleation truly.
Priority scheme of the present invention is: described body 1, fixed arm 2 and elastic arm 3 are one-body molded.
Above-described is only preferential embodiment of the present invention. It should be pointed out that to those skilled in the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, this is also considered as belonging to protection scope of the present invention.
