Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular, to a drainage tube fixator. Background Technology

[0002] Medical drainage tubes are commonly used medical devices in clinical treatment to drain internal fluids, blood, or other fluids. However, the fixation of drainage tubes has always been a challenge in clinical nursing. Traditional fixation methods (such as sutures, adhesive tape, and bandages) have problems such as easy dislodgement, infection, and patient discomfort. During the clinical use of drainage tubes, due to the need for drainage and to avoid adhesion between the drainage tube and surrounding tissues during prolonged drainage, which would hinder later removal, it is necessary to periodically rotate or adjust the position of the drainage tube in daily treatment and nursing care. This causes a series of problems. If the drainage tube is fixed with sutures, it needs to be sutured to the patient's skin again when refixing it, which not only causes the patient additional pain, but the suture fixation is not secure and is prone to breakage. If adhesive tape or bandages are used for fixation, their effectiveness is unsatisfactory. Adhesive tape is prone to peeling and falling off, and it is also easily soaked by exudate around the wound, making it difficult to effectively secure the drainage tube. When using bandages, it is difficult to find a point of leverage for fixation, and bandages are particularly ineffective when securing thicker, rigid drainage tubes, such as triple-lumen abdominal drainage tubes. Therefore, designing an efficient, safe, and comfortable drainage tube fixation device is of great significance. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a drainage tube fixator to avoid problems such as detachment and infection caused by traditional sutures or adhesive tape fixation.

[0020] Please refer to Figures 1 to 3As shown, Embodiment 1 of this utility model provides a drainage tube fixator, including a base 100, an adjustment structure, and a clamping member 200. The base 100 has a support protrusion 130 on its inner side, and the adjustment structure is fixed to the surface of the base 100. The clamping member 200 is disposed on the inner side of the support protrusion 130 and the telescopic end of the adjustment structure. The adjustment structure is used to adjust the distance between the two clamping members 200 so that the two clamping members 200 clamp and fix the drainage tube 400.

[0021] The base 100 is fixed to the patient's skin, and an adjustable structure (such as a spring or threaded structure) controls the spacing between the two clamps 200, allowing them to clamp or release the drainage tube 400. The support protrusion 130 provides stable support, ensuring even distribution of clamping force. This provides an adjustable fixation method, avoiding problems such as dislodgement and infection associated with traditional sutures or adhesive tape fixation. It is suitable for drainage tubes of different diameters, improving the convenience and safety of clinical use.

[0022] Two clamping members 200 are arranged opposite each other and are both arc-shaped. Protective plates 210, distributed along the height direction, are provided on the inner surface of each clamping member 200. The protective plates 210 are used to restrict and fix the drainage tube 400. The arc shape of the clamping member 200 matches the shape of the drainage tube 400, and the protective plates 210 increase the friction of the contact surface, preventing the drainage tube from sliding. The arc-shaped design reduces pressure damage to the drainage tube, and the protective plates 210 enhance the fixing effect, preventing the drainage tube from shifting or falling off.

[0023] The protective sheet 210 is made of silicone. The silicone material of the protective sheet 210 is elastic and has a high coefficient of friction, allowing it to fit tightly against the surface of the drainage tube. This reduces wear on the drainage tube, prevents slippage, and the biocompatibility of silicone lowers the risk of skin allergies.

[0024] The adjustment structure includes a sleeve 310, a spring 330, and a pull rod 320. The spring 330 is disposed inside the sleeve 310, and a baffle 321 is disposed on the pull rod 320. The clamping member 200 is fixed to the end of the pull rod 320. When the pull rod 320 is pulled, the baffle 321 compresses the spring 330.

[0025] When the lever 320 is pulled, the baffle 321 compresses the spring 330, causing the clamping member 200 to move to adjust the clamping distance; after being released, the spring 330 rebounds and automatically locks the drainage tube. This achieves rapid adjustment and automatic locking, is easy to operate, and is suitable for scenarios that require frequent adjustment of the drainage tube position.

[0026] The base 100 is generally ring-shaped, with connecting ears 110 on its side. The connecting ears 110 are used to secure the fixator to the body via a wide band. The connecting ears 110 can be used with the wide band (such as an elastic bandage) to further secure the base 100 to the patient's body. This enhances overall stability and prevents the fixator from shifting due to patient movement, making it particularly suitable for situations prone to traction, such as abdominal drainage.

[0027] The base 100 has a notch 120 to facilitate the installation of the drainage tube 400. The notch 120 design allows the base 100 to be inserted laterally into the placed drainage tube 400 without needing to install it from the tube end. This simplifies the installation process, avoids repeated disassembly and reassembly of the drainage tube, and reduces operation time and the risk of infection.

[0028] The base 100 is made of medical-grade silicone or plastic, and its surface is coated with hypoallergenic adhesive. The medical-grade silicone or plastic material is soft and hypoallergenic, and the hypoallergenic adhesive enhances adhesion to the skin.

[0029] Each clamp 200 contains a magnet, with the magnets in different clamps 200 having opposite polarities. The magnets in the clamps 200 create an attractive force when the two clamps are closed, enhancing the clamping strength. This prevents the drainage tube from accidentally dislodging due to external forces such as when the patient turns over, improving the reliability of fixation.

[0030] The arc-shaped structure of the clamping member 200 matches the shape of the drainage tube 400. The arc-shaped structure of the clamping member 200 fits perfectly against the outer wall of the drainage tube 400, dispersing pressure. Example

[0031] Please refer to Figure 4 As shown, Embodiment 2 of this utility model provides a drainage tube fixator. Unlike Embodiment 1, the adjustment structure includes a threaded sleeve 510, a handle 520, and a screw 530. The clamping member 200 is connected to the end of the screw 530, the handle 520 is fixed to the other end of the screw 530, the threaded sleeve 510 is fixed to the surface of the base 100, and the screw 530 and the threaded sleeve 510 are threadedly engaged. The clamping member 200 can be adjusted by rotating the handle 520.

[0032] The rotating handle 520 drives the screw 530 to move within the threaded sleeve 510, thereby precisely adjusting the spacing of the clamping component 200. This provides finer clamping force control and is suitable for applications requiring high fixation strength, such as rigid drainage tubes.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
