Description

Technical Field

[0001] The invention relates to the technical field of hemostat equipment, and in particular to a radial artery compression hemostat after coronary intervention. Background Art

[0002] Coronary artery intervention is a common method for clinical treatment of coronary heart disease. With the continuous improvement and miniaturization of cardiac catheter instruments, percutaneous puncture of the radial artery has begun to be adopted at home and abroad, among which postoperative hemostasis is particularly important. The compression hemostasis effect at the radial artery puncture site after surgery directly affects the patient's postoperative recovery speed. Usually, hemostasis methods include manual compression and mechanical compression. The radial artery compression hemostat is an arterial hemostasis tool placed on the wrist, which is mainly suitable for patients with large amounts of bleeding and critical conditions. The radial artery compression hemostat mainly achieves the purpose of hemostasis through compression, and usually needs to be used on the patient's wrist. However, the inventors found that the radial artery compression hemostat has the following defects during use: long-term compression causes itching and discomfort to the skin in the area. In addition, in the lower temperature environment in winter, the blood circulation is not smooth due to compression, and there is a temperature drop in the hand temperature. Therefore, those skilled in the art hereby propose a solution for radial artery compression hemostat after coronary intervention. Summary of the invention

[0003] In view of the defect mentioned in the above background technology that when the current compression hemostat device compresses the radial artery at the distal end to stop bleeding, the skin permeability of the compressed area is greatly reduced, causing itching and discomfort on the skin in the compressed area, a technical solution for a radial artery compression hemostat after coronary intervention is provided.
