Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to a kind of Ya Mai mechanism and torniquet.
Background technique
Current clinically common internal fistula hemostasis by compression mainly uses gauze piece, button, the gauze rolling for being cased with fingerstall, health
The devices such as paper protection pad, the arm-rest belt for carrying pulse-pressure body carry out hemostasis by compression or medical staff directly uses finger compressing to carry out
Hemostasis.Shortcoming existing for current hemostat devices mainly has:
Gauze piece is rectangle cloth pad, is in plane with pressure point contact position, and compressing dynamics is poor, and filling recess is insufficient, is held
Easy oozing of blood or subcutaneous hematoma, and gauze piece softens, the effect of hemostasis by compression will receive direct shadow at once once being polluted by bloodstain
It rings.
Because button is hard, poor plasticity, it is difficult to point of puncture peripheral recesses are filled, when skin penetrating point and vascular puncture point two
Point apart from it is larger when, can only oppress wherein, easily generation oozing of blood or subcutaneous hematoma.
Gauze rolling fingerstall method can solve the defect of first two, but gauze rolling be it is cylindric, and be oppressed location contacts area
Small, it is poor to align accuracy for easily sliding or slippage.Also, because its pulse-pressure body is fixed on arm-rest belt, needed in certain special circumstances
With hand by being not easy to realize when pulse-pressure body (or protection pad) hemostasis by compression, disinfection is also extremely inconvenient, when rubber fingerstall contact sterilizing agent
Or aging breakage is easy after water, it cannot be used for a long time.
Pollution is easy in toilet paper protection pad use process, once being soaked by blood, can soften at once influences haemostatic effect, and one
Secondary property is larger using wasting.The direct compression method of finger, it is not convenient enough, and it is added significantly to the workload of medical staff.
In the prior art, manually tighten arm-rest belt and change film bring inconvenience, large labor intensity and technical problem at high cost.
