Description

Tourniquet and fixed cutting device thereof

Technical Field

The invention relates to the technical field of medical care products, in particular to a tourniquet and a fixed cutting device thereof.

Background

The tourniquet is refined by medical high polymer material natural rubber or special rubber, has a flat or round strip shape and strong elasticity, is suitable for disposable use in the conventional treatment and treatment of medical institutions during injection, transfusion, blood drawing, blood transfusion and hemostasis, and can also be used for emergency hemostasis during limb bleeding and field snake and insect bite bleeding, and the tourniquet has overlong use time, so that blood backflow is blocked, blood vessels are expanded, and the blood pressure and blood flow in capillary vessels are increased and reduced to cause liquid loss. Continuous venous hypertension, reduced tissue reflux moisture and electrolytes, increased protein and protein conjugate concentrations; the blood flow is blocked, and the activity of fibrin is increased; the cells continue to metabolize, the metabolite lactic acid is increased, and the like, so the use time of the tourniquet is less than 1 minute, the tourniquet is preferably relaxed after the needle enters the blood vessel, and in order to avoid cross infection, the tourniquet needs to be discarded by one person, so the tourniquet is mostly used in clinic in units of strips.

At present, the existing tourniquet has the following defects:

1. at present, the tourniquet is an independent single clean package, so that the tourniquet is very inconvenient for clinical nurses to use, and particularly when blood sampling is concentrated in the morning or blood sampling is performed at a clinical laboratory window, the package needs to be disassembled before each use, and the work efficiency of the clinical nurses is greatly reduced due to the frequent use;

2. meanwhile, a large number of strip-shaped tourniquets need a large storage basket to be placed, so that a large amount of space of the treatment trolley is occupied, and operation of nurses is not facilitated;

3. in addition, in order to improve the working efficiency, some nurses only use one or a plurality of tourniquets when collecting blood, and different patients use hand-free disinfection liquid to disinfect or not disinfect, which is completely inconsistent with the principle that the tourniquets required by hospitals are discarded by one person.
