Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a coiling and fixing device for medical catheters. Background Technology

[0002] Medical catheters are tubular rubber products used in medical procedures, primarily in surgical operations. They have advantages such as good biocompatibility, aging resistance, and stable performance. During normal use, excessively long catheters need to be tidied up and positioned to prevent people from pulling on them and causing harm to the patient.

[0003] Current methods for managing and limiting tubing mostly involve using tools such as medical tubing clamps to manage and limit excess tubing segments. However, most tubing is exposed, and the clamps are suspended on the tubing, making it impossible to secure it, and there is still a risk of accidental pulling. Utility Model Content

[0004] The purpose of this utility model is to provide a medical catheter winding and fixing device. The device involves passing the medical catheter through a winding box and winding up any excess catheter segments using a winding structure. After winding, a suitable fixing method can be selected according to requirements. For outpatient visits, the first card insert can be inserted into the card slot, and the clip can be used to secure it to thin surfaces such as patient sheets or clothing, thus fixing the overall structure. For fixed-point use in hospital wards, the second card insert can be inserted into the card slot, and the clip can be used to engage with the mounting base installed at a fixed point in the ward, thus relatively fixing the overall structure. This provides two fixing methods, making it convenient to use and adaptable to various application scenarios. The medical catheter passes through the cable entry point through the box body and through the gap between the winding shaft and the actuating rod. By pulling the connecting shaft with the finger buckle, the locking pin disengages from the locking slot. A sliding block drives the winding shaft to rotate, and the actuating rod bends the catheter and provides a point of force for winding. After releasing the finger buckle, the locking pin re-engages with the locking slot for locking, thus solving the problems mentioned in the background art.
