Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a wrist support for radial artery puncture. Background Art

[0002] When the radial artery is punctured, the patient needs to maintain a specific posture before the puncture is performed. After the radial artery puncture, a radial artery hemostatic compressor is required to stop bleeding. The radial artery hemostatic compressor is a hemostatic device used after vascular intervention. It mainly compresses the radial artery puncture site from outside the body through mechanical pressure to promote hemostasis and healing of the puncture site. When the radial artery is compressed, the radial artery compression plate set on the compression hemostat is used to compress the patient's radial artery. The radial artery compression plate is driven by a threaded rod, so that the radial artery compression plate compresses the patient's radial artery to stop bleeding of the radial artery.

[0003] In the above-mentioned actual radial artery puncture operation, the patient's wrist needs to be maintained at a specific angle to facilitate the medical staff to perform the puncture operation. In the existing radial artery puncture operation, for the fixation of the palm, it is generally necessary to manually adjust the patient's wrist to an appropriate angle before the puncture is performed. After the puncture, the patient is required to maintain a specific angle for a period of time wearing a compression hemostat, generally about 24 hours. Therefore, the patient's wrist joint angle needs to be maintained for a long time, which is very difficult to operate in practice. Utility Model Content
