Pressurizing tourniquet

Abstract

The invention discloses a pressurizing tourniquet, relating to an artery tourniquet. Two ends of a fixing belt are provided with adhesive buckles, the fixing belt is equipped with a pressurizing plate and is also provided with a plurality of air bags at all the positions except for the position of the pressurizing plate, and the air bags are connected with a compression air bag via a communication tube; one end of the pressurizing plate is provided with a supporter and a pressurizing head is arranged near the other end thereof. The device according to the invention requires small pressure during hemostasia, has the advantages of comfortable use, simple and convenient operation, saving material and good recyclability, and lowers burden of patients.

Description

technical field [0001] The invention relates to an arterial tourniquet, in particular to a device for radial artery compression and hemostasis after radial artery puncture interventional operation. Background technique [0002] The existing radial artery compression tourniquet is provided with Velcro at both ends of the fixing band, a pressing plate is installed in the middle, and an air bag is arranged under the pressing plate. When in use, the air bag is pressed on the puncture site, and the air bag is inflated with a special inflatable syringe. The inflated balloon compresses the puncture site to achieve radial artery hemostasis. When deflated, it is also necessary to connect the special inflation syringe to the air bag to extract the air. The problems that exist are: 1) the area that the air bag contacts with the skin is relatively large, and to effectively compress the hemostasis at the puncture site, the air in the air bag needs to have a relatively high pressure.

AI Technical Summary

Problems solved by technology

The problems that exist are: 1) the area that the air bag contacts with the skin is relatively large, and to effectively compress the hemostasis at the puncture site, the air in the air bag needs to have a relatively high pressure. Under the same pressure, the fixing belt is a plastic belt, and its edge forms a shear force on the skin. During the several hours of hemostasis, the fixing belt causes blood flow under the skin to be blocked, causing numbness, bruising, and poor blood flow in the patient. It will further swell the skin, and even cause nerve damage and arterial occlusion in severe cases. Many patients cannot tolerate the pain. This phenomenon is especially common in obese patients.

[0003] 2) When the medical staff performs compression to stop bleeding, two people are required to operate, one person binds the fixing belt, and the other person uses a special inflatable syringe to inflate the air bag, and the work efficiency is low

Congested and swollen skin requires multiple adjustments of the air pressure in the airbag, and the operation of inflating and deflating is cumbersome

[0004] 3) Because the airbag part is in contact with blood, it can only be used once, which is a big waste and not environmentally friendly
