AI Technical Summary

Technical Problem

Existing enterostomy devices cannot effectively secure the catheter, leading to catheter slippage or displacement, making negative pressure drainage impossible, and causing leakage of excrement, resulting in complicated nursing care.

Method used

The device employs a double-layer catheter fixation assembly, including a base, main lumen tube, and metal fixation plate. Combined with the laminated structure of the ostomy bag and a sensor system, it ensures that the catheter is securely placed at the enterostomy site, enabling negative pressure drainage and smooth discharge of excrement. The device also monitors and automatically reminds users to change the catheter.

Benefits of technology

This method achieves stable fixation of the catheter, reduces the risk of slippage and displacement, ensures smooth drainage of excrement and stability of the tube, improves patient comfort and hygiene safety, and reduces the complexity of nursing care.
