[0002] With the advancement of medical technology and scientific and technological levels, nurses' nursing operation capabilities have gradually improved, and peripheral venous puncture central venous catheterization technology, such as arm infusion port and PICC, has also become increasingly popular. During the insertion of the central venous catheter, the patient's cooperation is required, the arm on the insertion side needs to be abducted about 90 degrees, and the arm needs to be turned over to cooperate with the operation, and this position needs to be maintained for a long time.

[0003] At present, clinical nurses mostly complete this operation in a dedicated catheterization room, but there is no dedicated catheterization equipment. In clinical operations, patients are sometimes asked to lie flat on the bedside opposite to the insertion side and stretch their arms as much as possible, but this poses a greater safety hazard and the insertion space is relatively limited, which is easy to contaminate the sterile area. Some people also add a small platform at the same height as the bed to solve the problem of operating space, but there is a problem that the patient cannot cooperate to rotate the wrist, making it difficult to achieve the best puncture position.

[0004] Most of the catheter fixing devices in the prior art are bulky, cannot be folded and contracted, take up space, and are inconvenient to adjust the angle. Therefore, improvements are needed. Utility Model Content
