Disposal radial artery compression hemostat

Abstract

The invention relates to a disposable radial artery compression hemostat, which mainly comprises a screw rod, a pressure regulating board and a pressure board, wherein the center of the pressure regulating board is provided with a convex block which is cut with a screw hole in which the screw rod is screwed and connected; the pressure board is connected below the screw rod, and the periphery and the bottom part of the pressure board are coated outside with a thin film; an air bag is formed between the thin film and the pressure board; the bottom surface of the thin film is provided with a gauze cloth; the both ends of the pressure regulating board are provided with penetrating holes which are penetrated by fixed belts. The invention has the advantages that: the disposable radial artery compression hemostat with the structure combines the original spiral type with the air bag type, which can not only maintain the advantages of the two, but can also overcome the deficiencies of the two; the invention can be selected for use under different situations or be used together, so as to achieve a better hemostatic effect. Furthermore, the bottom surface of the thin film is directly provided with the gauze cloth which can not be used again after the usage, so the hemostat can not be used for the second time, and the disposable method can avoid the risk of cross infection which is caused by a plurality of uses.

Description

technical field [0001] The invention relates to a medical hemostat, which is mainly a disposable compression hemostat acting on the radial artery. Background technique [0002] At present, the hemostasis of the radial artery after puncture still adopts the backward method of artificial finger pressure and bandaging. This is an empirical hemostasis method. If the pressure is too small, it is easy to cause bleeding; if the pressure is too high, it is easy to cause finger numbness and shaking, and even ischemia. , due to the use of manual pressure to stop bleeding, the strength of the implementation is not easy to maintain stable, often resulting in hemostasis failure, and it is necessary to press again to stop the bleeding. On the one hand, it increases the labor intensity of the doctor, and on the other hand, it also causes pain to the patient. Compression to the ulnar artery, due to the long duration of compression, can easily lead to arterial occlusion, and at the same time...

Problems solved by technology

[0002] At present, the hemostasis of the radial artery after puncture still adopts the backward method of artificial finger pressure and bandaging. This is an empirical hemostasis method. If the pressure is too small, it is easy to cause bleeding; if the pressure is too high, it is easy to cause finger numbness and shaking, and even ischemia. , due to the use of manual pressure to stop bleeding, the strength of the implementation is not easy to maintain stable, often resulting in hemostasis failure, and it is necessary to press again to stop the bleeding. On the one hand, it increases the labor intensity of the doctor, and on the other hand, it also causes pain to the patient. Compression to the ulnar artery, due to the long duration of compression, can easily lead to arterial occlusion, and at the same time block the venous return, resulting in congestion and swelling of the hands, increasing the pain of the patient. In addition, multiple people are required to cooperate in the operation of compression to stop bleeding. Inconvenient and reduces work efficiency

[0003] There are also some instruments for hemostasis on the market, mainly including spiral type and air bag type, but in the process of implementation, due to the uncertainty of the incident, neither of them can effectively stop bleeding. Effect

Moreover, because most of the hemostats are used repeatedly, there is a hidden danger of cross-infection, which brings certain dangers to the recovery of the patient's body.
