Air bag type tourniquet

Abstract

The invention discloses an air bag type tourniquet. The air bag type tourniquet comprises an adhesive tape, an inflation connecting assembly and a hemostasis air bag, wherein the inflation connecting assembly comprises an air bag pressing plate, a pipeline, a base, a connector, a sealing plug and a spring. The air bag pressing plate is installed on the back of the hemostasis air bag, the pipeline is connected with the bottom of the base and the air bag pressing plate, the bottom of the connector is connected with the top of the base, the sealing plug is arranged in the connector, and the spring is located between the sealing plug and the base. A limiting step for limiting the sealing plug is arranged in the connector, and the elastic force of the spring drives the sealing plug to abut against the limiting step so that sealing of the connector can be achieved. An injector is inserted into the connector and abuts against the sealing plug, the hemostasis air bag can be inflated, and after the injector is pulled out, air cannot be exhausted outwards through the inflation connecting assembly. The pressure of the hemostasis air bag on the compression point can be adjusted by adjusting the inflation amount injected into the hemostasis air bag, so that the requirement for the compression force of the puncture point in each stage is met, quantitative operation is achieved on the pressure of the bleeding point, operation is easy, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an air bag tourniquet. Background technique [0002] The tourniquet is mainly used for hemostasis after interventional surgery, such as angiography, percutaneous coronary angioplasty, stent placement, peripheral angioplasty and other interventional surgery. The strength of the traditional compression hemostasis method is not easy to maintain stability, often resulting in failure of hemostasis, requiring re-pressing to stop bleeding. On the one hand, it increases the labor intensity of medical staff, and on the other hand, it also causes pain to patients. [0003] There are many types of tourniquets currently available clinically for emergency use, and the most common ones are cassette type, cloth strip type, spinning type and inflatable type. Various types of tourniquets have different application ranges and clinical characteristics. Well-designed tourniquets can reliabl...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the inflatable device for an inflatable tourniquet in which the inflatable device and the tourniquet are integrally connected in the prior art. Due to the large volume and weight of the inflatable device, it is easy to cause pressure on the patient's skin and affect the patient's experience. defects, thereby providing an air bag tourniquet
