Problems solved by technology

[0002] Most of the existing medical tourniquets are made of narrow rubber tubes, which have the disadvantages of small contact area, the patient feels uncomfortable, and the patient's skin has strangulation marks during use, which is easy to cause local skin tissue to produce ecchymosis
Moreover, rubber tube tourniquets are not easy to disinfect, and repeated use is prone to cross-infection

Abstract

The invention belongs to the field of medical appliances and particularly relates to a tourniquet used for blocking blood stream when patients are subjected to venipuncture. The tourniquet is composed of a fixing band, a rectangular air bag and an elastic air inflating device, wherein the fixing band is formed by sewing A and B layers of terylene fabrics; the rectangular air bag is fixed in the interlayer between the A and B layers of terylene fabrics; the rectangular air bag is communicated with the elastic air inflating device which is provided with one-way air inflow valve and air discharge valve through a guide pipe; and the magnetic powder and metal iron powder are respectively plated on external side surfaces of A and B surfaces of the fixing band. The tourniquet has the advantages of simpleness in structure, convenience in use, reliability in hemostasis, large contact area with human body skin, low probability of petechia generation, capability of being repeated used, easiness in disinfection and capability of effectively reducing the cross infection.

Description

【Technical field】 [0001] The invention relates to a tourniquet used in venipuncture, belonging to the field of medical instruments. 【Background technique】 [0002] Most of the existing medical tourniquets are made of narrow rubber tubes, which have the disadvantages that the contact area is small, the patient feels uncomfortable, and the patient's skin has strangulation marks during use, which easily causes local skin tissue to produce ecchymosis. Moreover, the rubber tube tourniquet is not easy to be sterilized, and repeated use is prone to cross-infection. 【Content of invention】 [0003] The object of the present invention is to overcome the above disadvantages and provide a tourniquet with simple operation and convenient use. [0004] The technical solution adopted by the present invention to solve the technical problem is: the tourniquet is composed of a fixing belt, a rectangular air bag and an elastic inflating device, the fixing belt is made of A and B two-layer po...
