Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a wrist restraint structure for patients with radial artery catheterization. Background Technique

[0002] Arterial catheterization not only provides a real-time, accurate, and continuous dynamic blood pressure monitoring approach for clinical treatment, but also provides a fast and effective arterial blood collection channel, greatly reducing the damage to blood vessels caused by repeated punctures, thereby reducing the pain and infection rate of patients, and also improving the work efficiency of nursing staff, playing an important role in the treatment of critically ill patients. Due to its superficial location, convenient and safe puncture operation, high success rate, and few complications, the radial artery has become the preferred site for invasive blood pressure monitoring in clinical practice.

[0003] Most of the existing wrist restraint structures fix the radial artery catheterization by tying it with a restraint band, and then use a net racket-shaped restraint structure to cover the hand inside to prevent the hand from moving and causing the catheter to displace and return blood. This makes it difficult to observe the restraint site and requires removing the restraint band and the net racket-shaped restraint structure when measuring finger tip blood glucose, with cumbersome operations. Therefore, a wrist restraint structure for patients with radial artery catheterization is designed to overcome the above technical deficiencies. Content of the Utility Model
