A tourniquet with automatic pressure release at regular intervals

Abstract

The invention belongs to the field of medical auxiliary instruments, and relates to a tourniquet capable of depressurizing automatically and regularly. The tourniquet comprises a tourniquet body, styptic cotton, a tightening unit, a control unit, a timer, sensors and an energy supplying unit, the tourniquet body is used for wrapping a wounded part of a user, the styptic cotton is used for stoppingbleeding of the wounded part of the user, the tightening unit is used for applying pressure on the styptic cotton to stop bleeding or relieving the pressure applied on the styptic cotton, the sensorsare used for acquiring data in a bleeding stopping process, and the control unit is used for controlling actions of the tightening unit according to the data acquired by the sensors. The tourniquet has the advantages that pressing strength and pressing time can be quantized, bleeding stopping time in the bleeding stopping process can be guaranteed effectively, a bleeding stopping effect can be affirmed in the bleeding stopping process, operations of medical workers is facilitated, medical efficiency can be increased effectively, and the circumstance of flooding or long-time blood stopping canbe avoided.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, and relates to a tourniquet with automatic pressure release at regular intervals. Background technique [0002] During medical procedures, it is often necessary to use a tourniquet. Sometimes it is necessary to use a tourniquet for hemostasis, but the traditional tourniquet has the following disadvantages. It is impossible to clearly record the hemostasis time, and the user needs to record it by himself. Often, the compression time is insufficient or the compression time is too long; the hemostatic effect cannot be clearly known , it is necessary to loosen the tourniquet to see if there is any rebleeding phenomenon, which is prone to blood collapse. [0003] In DSA lower extremity deep venography, it is necessary to inject iodine contrast agent into the patient's bilateral foot dorsal puncture indwelling needles to observe the blood vessels of the lower extremities. At the same time, ...

AI Technical Summary

Problems solved by technology

At this time, it is easy to cause pollution, and the inspection effect is different due to the different tightening strength each time.

Or forget to loosen the tourniquet because of discussing the condition and observing the image, which will cause the patient's lower limbs to be under pressure for a long time, affecting the blood supply of the lower limbs and causing damage
