Description

Technical Field

[0001] The utility model relates to the technical field of hemostats, in particular to a novel radial artery compression hemostatant. Background Art

[0002] The radial artery compression hemostat is a medical device used to stop bleeding, usually used in emergency and surgical operations. In recent years, with the development of biomedical engineering and medical technology, a new radial artery compression hemostat has been proposed to provide a more precise and efficient method of stopping bleeding. This new hemostat may be made of advanced materials, have better elasticity and adjustability, and can apply pressure more accurately and better adapt to the needs of different patients.

[0003] After searching, the existing patent (Announcement No.: CN216933358U) discloses a new radial artery compression hemostat, including an annular support ring and a mounting shell, a control circuit board and a rechargeable battery are arranged in the mounting shell, the control circuit board and the rechargeable battery are connected by a wire, and the side of the annular support ring is symmetrically connected with a strap; the mounting shell is connected to the side of the annular support ring, a display screen is arranged on the top of the mounting shell, a pressure sensor is installed on the side of the mounting shell close to the center of the annular support ring, and the pressure sensing surface of the pressure sensor is connected to the annular support ring; it also includes a compression airbag, the compression airbag is located at the bottom of the annular support ring, the annular ring is connected to the top edge of the compression airbag, the annular ring is located in the annular support ring, and the top of the annular ring is fixedly connected to the top of the annular support ring, and a sealing cover plate is sealed at the top of the annular ring. When the utility model is used, it is worn on the arm through a strap, and then the compression airbag is inflated to press the compression airbag on the puncture position.

[0004] However, in the actual use of the above solution, the length of the bandage is not fixed, but the size and anatomical structure of the human body vary from individual to individual, and some patients may need tighter or looser compression to achieve the best hemostasis effect. If the length of the bandage cannot be adjusted, it may not meet the needs of different patients, thus affecting the hemostasis effect. At the same time, if the length of the bandage cannot be adjusted, it may be too tight or too loose. Too tight compression may damage blood vessels and surrounding tissues, and even cause complications such as ischemia; while too loose compression may not be able to effectively stop bleeding, increasing the risk of bleeding.

[0005] In view of this, the utility model proposes a novel radial artery compression hemostat. Utility Model Content
