Description

Fixed seat for radial artery puncture

technical field

The utility model relates to the field of medical equipment, in particular to a fixed seat for radial artery puncture.

Background technique

All kinds of critically ill patients with severe shock and cardiopulmonary failure in the intensive care unit need to closely monitor changes in blood pressure, or need to repeatedly take arterial blood samples for blood gas analysis and electrolyte measurement, etc. The radial artery is often the first choice. The advantage is that it is convenient for puncture and management. Generally, when puncturing, put a small pillow on the wrist and flex the back of the hand by 60 degrees, and abduct the arm on the side of the puncture by about 20 degrees. The middle finger and ring finger touch the strongest pulsation point of the radial artery, and it is in a straight line along the direction of the artery. The index finger is the puncture target, and the straight line formed by the three fingers is the needle insertion direction. The angle between the puncture needle and the skin is between 30 and 45 degrees. At present, saline pads are generally used on the back of the wrist, and the palm is fixed with adhesive tape. The position and angle cannot be adjusted according to the hand shape of different patients, and the success rate of puncture is very low.
