Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a radial artery blood sampling fixing pressurizer. Background Art
[0002] The radial artery is superficial, easy to touch, and convenient for puncture, so radial artery puncture is often used clinically to collect arterial blood samples for blood gas analysis. Due to the large blood flow in the artery, the puncture point often needs to be compressed to stop bleeding after blood collection from the radial artery, and the compression time is often 10-30 minutes. The currently used radial artery compression hemostat is mainly composed of a wrist strap, a buckle plate, a screw cap, a compression rod and a cushion. The buckle plate is fixed to the wrist through the wrist strap, and the screw cap is turned to adjust the extension and contraction of the compression rod, so that the cushion compresses the radial artery puncture point to stop bleeding. The currently used radial artery compression hemostat has a good compression hemostasis effect, but it still has the following defects: 1. It is impossible to restrain the arm for radial artery blood sampling. When positioning the puncture of the radial artery, the movement of the arm will lead to failure of puncture positioning, especially for some pediatric patients; 2. The position of the compression rod of the compression hemostat is fixed and cannot be adjusted, that is, the left and right position and the compression angle of the compression rod cannot be adjusted. In clinical practice, the position of the puncture point of the radial artery is not fixed, which results in the compression point of the compression rod still being outside the range of the puncture point after repeated adjustments of the wrist strap and the buckle plate.
