Description

Technical Field

[0001] The invention relates to the field of tourniquets, in particular to a self-disinfecting adjustable tourniquet. Background Art

[0002] Intravenous infusion is the most important part of clinical nursing for nurses. In the course of work, they often encounter an increase in nursing workload due to unreasonable nursing tools. There are currently two types of tourniquets used for intravenous infusion, both of which are made of rubber. One is a vacuum round type, which needs to be soaked and disinfected before reuse. The vacuum round rubber tube is lighter and will float on the disinfectant during soaking and disinfection, resulting in incomplete disinfection. The other is a wide type, which is disposable and discarded after use, increasing the use of consumables. Both of these tourniquets cannot control the pressure well during use. Normally, the tourniquet is used during intravenous infusion. The pressure is 10.7-16.0kpa. The pressure of the tourniquet currently used in clinical practice cannot be observed intuitively. The nurse may tie the tourniquet very tightly during use, so that the blood vessels will be more easily visible. However, a tourniquet that is too tight may cause small blood vessels to rupture, and the patient will feel pain, etc., resulting in poor subjective experience for the patient. A tourniquet that is too loose increases the difficulty of puncture and causes unsuccessful puncture, causing pain to the patient. During the infusion process, the tourniquet may automatically pop open due to problems such as the tourniquet material. Therefore, a self-disinfecting adjustable tourniquet is proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a self-disinfecting adjustable tourniquet, which can solve the problems that the traditional tourniquet cannot adjust the tightness and is inconvenient to disinfect after use.
