Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing tools, in particular to a radial artery puncture auxiliary device. Background Art

[0002] When performing arterial blood gas puncture, it is necessary to find the radial artery. However, the radial artery is not as superficial as the vein. The radial artery first passes between the brachioradialis and the pronator teres, then descends between the brachioradialis tendon and the radial flexor carpi tendon, goes around the radial styloid to the back of the hand, passes through the first metacarpal space to the palm, and anastomoses with the deep palmar branch of the ulnar artery to form a deep palmar arch. Therefore, when puncturing, the nurse needs to feel the strongest point of the arterial pulsation for puncture.

[0003] However, the skin of elderly and thin patients is loose. If the above method is used, the nurse must feel the strongest point of the arterial pulsation and forcefully bend the patient's hand down to tighten the skin when performing the puncture. Completing these two actions with one hand (the other hand needs to hold the puncture needle) will greatly increase the difficulty of successful puncture and the patient's pain during puncture.
