AI Technical Summary

Technical Problem

Existing hemodialysis catheter fixation devices can only fix catheters of a specified size and cannot accommodate catheters of different sizes. Furthermore, the carbon steel bend is a fixed structure, which makes it inconvenient to adjust the height and reduces its practicality.

Method used

A hemodialysis catheter fixation device was designed, which includes adjustment components and fixation components. By using a universally adjustable carbon steel bend and support column, combined with adjustable first and second fixation seats, heating wires and heat conduction plates, it can fix catheters of different sizes and adjust their height. The device also uses Velcro to enable the linkage between the patient's body and the catheter.

Benefits of technology

It achieves stable fixation of catheters of different sizes, improves applicability and dialysis comfort, and enhances catheter stability and height adjustment capability.

Abstract

The application provides a hemodialysis catheter fixing device, belonging to the technical field of hemodialysis. The hemodialysis catheter fixing device comprises an adjusting assembly and a fixing assembly. The device is first fixed at the arm of a patient, realizing the linkage of the body of the patient and the fixed catheter of the device. The universal adjustment of the carbon steel elbow pipe is realized, the support column can be extended by moving the support column, and the support column can be fixed by rotating the knob, so that the catheter can be fixed. Since the first fixing seat and the second fixing seat are provided with first grooves and second grooves of different sizes on one side, different sizes of catheters can be fixed, which is convenient to use. The liquid passing through the catheter is heated by the heating wire, the heat conducting plate and the interlayer cloth, which is beneficial to improve the comfort of dialysis, and thus it is convenient to fix catheters of different sizes, which is convenient to adjust the height of the catheter, has high applicability, and thus improves the practicality.
