AI Technical Summary

Technical Problem

The existing Silex catheter cannot effectively prevent changes in insertion depth caused by patient movement during use, which may lead to the catheter falling out of the insertion area, affecting the stability and safety of use.

Method used

An insertable catheter fixation device is used, including a base, a top cover, a squeezing element, a protective component, and a support mechanism. The squeezing element limits the position of the catheter, the protective component and the support mechanism protect the periphery of the catheter, and the installation mechanism is used to adhere to the patient's skin to ensure the stability of the catheter position.

Benefits of technology

It effectively prevents changes in catheter insertion depth caused by patient movement, improves the safety and stability of catheter use, avoids tearing wounds in the catheter insertion area, and ensures the normal operation of the catheter.

Abstract

This invention discloses an insertion-type catheter fixation device, belonging to the field of medical tool technology. It solves the problem that existing fixation devices cannot prevent changes in the insertion depth of the catheter due to patient movement or bending at joints. The fixation device includes a base, a top cover, and a compression member. The top cover is installed on the base and covers the opening at the top of the base. The compression member is installed inside the base. A protective component is installed at the end of the base. The protective component protects both ends of the base and limits the insertion depth of the catheter, preventing changes in the insertion depth due to patient movement or bending at joints. An installation mechanism is installed at the bottom of the base to assist in the stable fixation of the base and ensure the stability of the fixation device during use.
