Description

technical field [0001] The invention relates to a continuously adjustable cuff device. Background technique [0002] Before venipuncture, medical personnel usually tie an elastic cuff on the upper part of the patient's puncture to slow down the return of venous blood, so that the local blood vessels can be filled to facilitate successful puncture, and at the same time, it is convenient to draw enough venous blood. The current tourniquet is generally cut from an ordinary elastic silicone tube. Because the diameter of the silicone tube is small, the force-bearing area at the binding site is small, and the pressure on the body tissue is relatively large. Feel pain of varying degrees. Because the pressure is difficult to control during the use of the existing cuff, and in special patient groups such as edema patients or patients who need to puncture the lower limbs, it often causes damage to the patient and leads to skin damage. At the same time, the cuff needs to be manually ...

AI Technical Summary

Problems solved by technology

Due to the difficulty in controlling the pressure during the use of the existing cuff, and in special patient populations such as patients with edema or patients who need to puncture the lower limbs, it often causes damage to the patient and leads to skin damage

At the same time, the cuff needs to be manually bundled and disassembled every time it is used, which makes the medical staff work intensively and have low work efficiency.
