Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, specifically to a drainage tube fixing device and a drainage tube. Background Technology

[0002] A drainage tube is a medical device used in clinical surgery to drain pus, blood, and fluid accumulated between body tissues or in body cavities, preventing postoperative infection and promoting wound healing. Many types of surgical drainage tubes are used clinically; some are used for urinary catheterization, others for wounds, and they are used in the thoracic cavity, brain cavity, gastrointestinal tract, and biliary tract, among others. Surgical drainage aims to drain pus, blood, and fluid accumulated between body tissues or in body cavities to prevent postoperative infection and to prevent impaired wound healing. When using a drainage tube, certain fixation devices are required.

[0003] Existing drainage tube fixing devices have been found to use stickers, which can easily cause the drainage tube to detach from the sticker. Once the drainage tube falls off, it cannot be reused, and the drainage tube cannot be securely fixed. This reduces the efficiency and effectiveness of the drainage tube, resulting in poor practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a drainage tube fixing device and a drainage tube.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a drainage tube fixing device and a drainage tube, which have the following beneficial effects:

[0017] Multi-level fixed structure to improve stability

[0018] The height of the sliding plate can be adjusted by bolts to accurately position and fix the device according to the patient's body part, avoiding the displacement problem caused by the curvature of the skin or movement of traditional stickers; the clamping grooves of the first and second clamps form a ring-shaped fixation, which, together with the elastic tightening force of the elastic telescopic rod, can adapt to drainage tubes of different diameters, ensuring dual fixation in both longitudinal and lateral directions, and significantly reducing the risk of falling off.

[0019] Flexible protection and anti-slip design, balancing safety and reliability.

[0020] The curved structure of the top plate and the protective rubber pad fit the surface of the drainage tube, reducing damage to the tube from hard compression; the anti-slip texture design increases friction and prevents the tube from shifting due to fluid flow or patient movement; the internal spring of the elastic telescopic rod provides a cushioning effect, absorbing vibration when the patient moves, and preventing wear or breakage of the tube at the fixation point.

[0021] Easy to operate and can be repeatedly adjusted

[0022] The screw drive structure between the rotating handle and the first lead screw allows for rapid adjustment of the clamping force through rotation, eliminating the need for tools and enabling single-person operation by medical staff. The sliding connection design between the sliding plate and the medical stent supports the repeated use of the fixation device in different locations, improving its clinical applicability.
