Further, the free end of this utility model fixed arm wherein is also provided with protuberance, when liquid stopping clamp closes, under the free end of described elastic arm is fastened on described protuberance.
Priority scheme of the present utility model is: described body, fixed arm and elastic arm are one-body molded.
This utility model 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 clamped condition, 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 second body tight lock part and the second elastic arm tight lock part are against arranging to clamp tube for transfusion, liquid in tube for transfusion can not be flowed, simultaneously, body extruding discharge opeing portion and elastic arm extrude the mutual extruding tube for transfusion in discharge opeing portion and produce transfusion malleation, guarantee that the liquid in tube for transfusion is pushed ahead, can prevent from blocking venous detaining needle or entry needle syringe needle with blood in blood backflow to tube for transfusion, thus avoid the formation of thrombosis.
Four, accompanying drawing explanation
Fig. 1, be according to the structural representation that the utility model proposes;
Fig. 2, be the schematic diagram that this utility model coordinates with tube for transfusion.
Five, detailed description of the invention
Below in conjunction with drawings and Examples, structure of the present utility model is further described:
Labelling 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, tube for transfusion fixing hole; E, tube for transfusion; K, protuberance.
In the drawings, this utility model liquid stopping clamp comprises body 1, and the side of described body 1 is provided with fixed arm 2, and opposite side is provided with elastic arm 3.Described fixed arm 2 and elastic arm 3 are equipped with the tube for transfusion fixing hole D allowing that tube for transfusion E passes.When using this utility model, tube for transfusion E passes from the tube for transfusion fixing hole D described fixed arm 2 and elastic arm 3.The free end of described fixed arm 2 and free end clamping when liquid stopping clamp closes of elastic arm 3; The free end of described fixed arm 2 is also provided with protuberance K, when liquid stopping clamp closes, under the free end of described elastic arm 3 is fastened on described protuberance K.
Described body 1 is provided with the first noumenon tight lock part A1, and described elastic arm 3 corresponding the first noumenon tight lock part A1 is provided with the first elastic arm tight lock part A2; Described body 1 is also provided with body extruding discharge opeing portion B1 in the first noumenon tight lock part A1 connection, described elastic arm 3 corresponding body extruding discharge opeing portion B1 is provided with elastic arm extruding discharge opeing portion B2.
Described body extruding B1 side, discharge opeing portion is also provided with the second body tight lock part C1, and described elastic arm 3 corresponds to the second body tight lock part C1 and is provided with the second elastic arm tight lock part C2.
This utility model is under the state opening liquid stopping clamp, namely 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, described body extruding discharge opeing portion B1 and elastic arm extruding discharge opeing portion B2, described second body tight lock part C1 and the second elastic arm tight lock part C2 do not extrude tube for transfusion E, like this, the liquid in tube for transfusion E can freely flow in tube for transfusion E.When this utility model is under the state of closing liquid stopping clamp, namely the free end of described fixed arm 2 and the free end of elastic arm 3 are under clamped condition, described the first noumenon tight lock part A1 and the first elastic arm tight lock part A2, described body extruding discharge opeing portion B1 and elastic arm extruding discharge opeing portion B2, described second body tight lock part C1 and the second elastic arm tight lock part C2 also clamps tube for transfusion E continuously against setting, at this moment, liquid in tube for transfusion E can not flow from the side of clamping point to opposite side, and, described body extruding discharge opeing portion B1 and elastic arm extruding discharge opeing portion B2 mutually extrudes tube for transfusion E and produces a transfusion malleation, liquid in tube for transfusion E is pushed ahead, can prevent from blocking venous detaining needle or entry needle syringe needle with blood in blood backflow to tube for transfusion E, thus avoid the formation of thrombosis.
Why this utility model is also provided with body extruding discharge opeing portion B1 in the first noumenon tight lock part A1 connection, described elastic arm 2 corresponding body extruding discharge opeing portion B1 is provided with elastic arm extruding discharge opeing portion B2, when this utility model is under the state of closing liquid stopping clamp, strengthen clamping tube for transfusion E, by the fluid balance extruding in tube for transfusion E, make effectively to produce a malleation of infusing between the clamping point of described tube for transfusion E and human transfusion part.
Why this utility model is also provided with the second body tight lock part C1 in described elastic arm extruding B1 side, discharge opeing portion, correspond to the second body tight lock part C1 at described elastic arm 3 and be provided with the second elastic arm tight lock part C2, this mutually extrudes tube for transfusion E except it and produces except transfusion malleation, or to the first noumenon tight lock part A1 and the first elastic arm tight lock part A2, body extruding discharge opeing portion B1 and elastic arm extruding discharge opeing portion B2 extrudes the further raising of tube for transfusion E reliability: this also clamps tube for transfusion E due to the second body tight lock part C1 and the second elastic arm tight lock part C2 simultaneously, even if under being returned to the protuberance K of fixed arm 2 free end after the free end of elastic arm 3 is pressed, liquid in tube for transfusion E also cannot flow backwards again, from and many one heavy technical measures effectively guarantee that tube for transfusion E infuses the generation of malleation, avoid the phenomenon occurring any negative pressure.
Application this utility model, can make tube for transfusion E realization transfusion malleation truly.
