Description

technical field [0001] The invention relates to a cuff, in particular to a cuff with alarm and automatic release functions, belonging to the technical field of medical instruments. Background technique [0002] The cuff is almost a nursing product that the nursing staff will come into contact with every day. It plays a role in blocking the blood flow, filling the veins, and facilitating the puncture of the nursing staff. Almost every nursing staff has the opportunity to use this clinically common and inconspicuous "little object". It is precisely because the cuff is too common that the nursing staff relaxes their vigilance and sometimes forgets to treat it in time after the puncture occurs. Take off the tourniquet and make the tourniquet stay on the patient's limb for too long, which can lead to local limb necrosis of the patient, and in severe cases require amputation or even life-threatening. In the past few years, there were news reports that the cuffs were forgotten to ...

AI Technical Summary

Problems solved by technology

[0003] In addition, the currently commonly used cuff is a rubber circular leather tube. The disadvantages are: 1. The contact surface with the skin is relatively small. For patients with thin skin or edema, the cuff is likely to cause skin pressure damage when tied for a long time.

2. If the current cuff is not tied well or the rubber tube is relatively new, it is easy to cause the rubber tube to loosen automatically, affecting the operation

3. The cuff currently used has no time reminder function

4. The color of the rubber tube is close to the skin and is not eye-catching. It is easy for the operator to forget to loosen the cuff after the operation.

But this scheme has the following problems: 1. After reaching the specified time, although the timer gives a reminder, if the medical staff does not find out in time, the cuff will still continue to remain in the oppressive state, and there is still no small risk; 2. Medical staff tend to forget to turn on the timer because they are busy when using it
