AI Technical Summary
Existing closed drainage devices are prone to loosening during use because the fixed end of the drainage tube is easily pulled, folded, twisted or compressed, which increases the risk of loosening, affects the patient's recovery and treatment effect, and causes fear.
The system employs a combination structure of elastic support, elastic frame, and arc-shaped clamping plate. The elastic force of the elastic support and the multi-angle fixation of the arc-shaped clamping plate counteract the tensile force and prevent the fixed end of the drainage tube from moving or loosening.
It effectively prevents the drainage tube from loosening, improves the fixation effect, increases the safety and stability during wearing, reduces patients' fear, and enhances the treatment effect.
