Description

Wrist fixing device after radial artery puncture operation

Technical Field

The utility model relates to a wrist fixing device after radial artery puncture, and belongs to the technical field of medical appliances.

Background

Radial artery puncture is a frequently performed technique of operation by anesthesiologists for clinical anesthesia management, for intra-operative monitoring of invasive arterial pressure to guide anesthesia management. After induction of anesthesia, the patient who receives general anesthesia will have his arms placed on the body side, except for the special surgical position. However, such a posture has the following problems:

1. After the consciousness of the general anesthesia patient disappears, as the tension balance of the forearm flexor and the extensor changes, part of the patient is in a wrist-flexed state, the radial artery lumen is narrowed under pressure to different degrees, the invasive arterial pressure reading is inaccurate, and the accuracy of the intraoperative management is affected;

2. During surgery, arm abduction can avoid inaccurate invasive arterial pressure readings due to mechanical compression, but this posture may interfere with the surgical procedure. Moreover, the surgeon may press the radial artery catheterization side arm of the patient during the operation, resulting in inaccurate or failed invasive arterial pressure readings;

In response to the above problems in clinical practice, rigid articles are often strapped or fastened to the back side of the patient's wrist to secure the wrist position, which may result in localized skin pressure damage.
