Description

Technical Field

[0001] The invention relates to the technical field of radial artery hemostat, in particular to a radial artery hemostat capable of automatically adjusting a pressing direction. Background Art

[0002] As people's living standards continue to improve, the incidence of coronary heart disease is getting higher and higher. Percutaneous coronary intervention is one of the most important means of treating coronary heart disease, and the first choice of this interventional surgery clinically is coronary artery intervention via the radial artery.

[0003] Hemostasis at the puncture site is an important part of this operation. Currently, a tape-type elastic bandage or a special radial artery hemostat is commonly used to stop bleeding at the puncture site. Continuous pressure is required for 4-6 hours until the puncture site stops bleeding.

[0004] However, traditional hemostasis methods have the following disadvantages:

[0005] (1) Since the human wrist is not a flat surface but has an arc and slope, the products currently on the market cannot adjust the direction of pressure by themselves, resulting in one side being pressed tightly and the other side being pressed loosely, which leads to poor hemostasis. If both are adjusted to be pressed very tightly, it will lead to uneven force. The position with excessive force will have the risk of complications such as pressure injury and arterial occlusion. At the same time, it will cause the patient's limb to swell and hurt significantly after surgery, and the patient's experience will be very poor.

[0006] (2) Since the human wrist is not a flat surface but has curvature and inclination, the fixing plates of products currently on the market are not ergonomically designed, which results in slipping easily after being worn and difficulty in aligning the radial artery. As a result, the center position of the pressing piece deviates from the puncture point during use, resulting in poor hemostasis effect. Summary of the invention

[0007] The object of the present invention is to provide a radial artery hemostat with self-adjusting compression direction, so as to solve the problem raised in the above background technology that since the human wrist is not a plane but has curvature and inclination, the current products on the market cannot adjust the direction of pressure by themselves, resulting in one side being pressed tightly and the other side being pressed loosely, resulting in poor hemostasis effect. If both are adjusted to be pressed very tightly, it will cause uneven force, and the position with excessive force will have the risk of some complications such as pressure injury and arterial occlusion, and at the same time cause the patient's surgical limb swelling and pain to be very obvious, and the patient's experience is very poor; since the human wrist is not a plane but has curvature and inclination, the fixing plates of the current products on the market are not ergonomically designed, resulting in easy slippage after being worn, and it is not easy to align with the position of the radial artery, which will cause the center position of the pressing piece to deviate from the puncture point during use, resulting in poor hemostasis effect.
