Description

A body position fixation device for radial artery puncture

technical field

The utility model belongs to the arterial puncture technical field, in particular to a body position fixing device for radial artery puncture.

Background technique

Arteriovenous puncture is a surgical procedure. For patients in severe shock who need first aid, the situation has not improved after rapid venous blood transfusion. It is necessary to increase coronary perfusion and increase effective blood volume through the artery. When puncturing, the operator wears a cap and mask, stands on the puncture side of the patient, wears sterile gloves, and uses the index and middle fingers of the left hand to fix the artery to be punctured at the 2 cm arterial pulse on the radial wrist joint. Hold the syringe in the right hand (washed with heparin saline), and insert it between two fingers vertically or at an angle of 40 degrees to the direction of the artery. If you see bright red blood going straight into the syringe, it means the artery has been pierced. Use the left hand to fix the direction and depth of the original puncture needle, and the right hand to inject the liquid medicine or collect blood at the maximum speed. After the operation is completed, quickly pull out the needle, and apply local pressure for not less than 5 minutes.

During manual arterial puncture, patients tend to shake their arms, which may lead to failure of the puncture operation. For this reason, the existing patent "201310391570.3" "A Fixing Device for Arterial Puncture" discloses "a fixing device for arterial puncture. The arc-shaped structure, the arm support plate is composed of arc-shaped hard board, sponge lining and cotton surface layer from the inside to the outside, one side of the cotton surface layer is connected with a fixing belt, and the end of the fixing belt is equipped with a Velcro , the fixed liner is an elastic cylinder structure, the fixed liner is arranged on one side of the puncture needle on the arm, and is fixed by wrapping the arm with a fixing belt."
