AI Technical Summary

Technical Problem

Existing thoracic tubes are prone to slipping or being pulled during patients' daily activities, causing discomfort and increasing the risk of wound tearing, thus affecting patients' quality of life and rehabilitation outcomes.

Method used

A thoracic tube positioning device was designed, comprising a first dressing section, a medical rubber ring, a retaining ring assembly, and a catheter fixation structure. By adjusting the distance between the dressing sections and the tightness of the retaining ring assembly, the tube is kept in a relaxed state, reducing the discomfort of tube sagging and traction. Furthermore, the design of the medical rubber ring and the ring sleeve reduces the direct force applied to the wound.

Benefits of technology

It effectively reduces the discomfort caused by the drainage tube falling or being pulled due to patient activity, reduces the risk of wound tearing, and improves the patient's quality of life and the safety of tube management.

Abstract

The present application belongs to the technical field of medical apparatus and instruments, and particularly relates to a chest tube positioning device for thoracic surgery nursing, which comprises a first dressing part, a medical rubber ring, a second dressing part, a catheter fixing part, a clamping ring assembly and a clamping strip arranged on the clamping ring assembly. The first dressing part is coated with the medical rubber ring and attached to the skin. One end of the clamping strip can be inserted into the interior of the clamping ring assembly and change the clamping degree of the clamping ring assembly. The clamping ring assembly is sleeved on the medical rubber ring, clamps the medical rubber ring and the chest tube and keeps them fixed. The second dressing part has a spacing with the first dressing part. The catheter fixing part is arranged on the second dressing part. The present application can effectively reduce the discomfort caused by the drainage tube caused by the patient's daily activities. The pulling force will not directly act on the wound, reducing the risk of secondary trauma caused by improper management of the tube.
