Description

Technical Field

[0001] This utility model relates to the field of catheter fixation equipment technology, and in particular to a catheter fixation device. Background Technology

[0002] In the medical field, especially during surgery and postoperative recovery, drainage tubes are frequently used to drain fluids from a patient's body, such as blood and lymph. To avoid accidental tube removal and ensure patient comfort, the method of securing the drainage tube is crucial, thereby guaranteeing both effective drainage and patient safety.

[0003] Traditional catheter fixation methods use rubber bands to wrap the catheter around the patient's clothing, which is prone to slippage and accidental pull-out. Therefore, some catheter fixation devices have emerged that use clips and rubber bands in combination. The rubber band is connected to both the catheter and the clip, which is then secured to the patient's clothing. While this method is simple and convenient, it still has some drawbacks. First, catheter stability is poor. Since the rubber band is simply wrapped around the catheter, changes in the catheter's position during patient movement or the pull of the drainage bag's fluid can cause relative slippage between the catheter and the rubber band, leading to accidental pull-out. Second, the clip structure only provides a simple clamping method, and the fixation is limited, easily slipping off the clothing and becoming ineffective. Third, the rubber band's high elasticity allows it to deform under external force, failing to effectively fix the catheter's position during use. Furthermore, the rubber band fixation method requires instruction from medical professionals or assistance from others, making it difficult for individuals, older patients, or those with poor fine motor skills to operate.

[0004] There are still no effective solutions to the problems in related technologies, such as unstable catheter fixation, limited adaptability of clamp fixation methods, and complex operation with limited use. Utility Model Content

The first and second clothing clamping units work together to fix the catheter clamping unit in the desired position, offering diverse fixation methods, expanding its application range, improving patient comfort, and reducing the risk of accidental catheter removal. Patients can freely operate the clamps anytime, anywhere as needed, overcoming the problems of limited adaptability, complex operation, and restricted use associated with traditional clamp fixation methods.

The clothing is clamped by the first limiting element 18 and the second limiting element 28 and is not on the same horizontal plane as the clothing clamped by the first main clamping element 11 and the second main clamping element 21. When the first auxiliary clamping element 17 and the second auxiliary clamping element 27 are used to clamp the clothing onto the buttonhole, trouser loop, etc., the first limiting element 18 and the second limiting element 28 are connected in a limiting manner to prevent the clothing from sliding out between the first main clamping element 11 and the second main clamping element 21.

The second catheter clamping element 61 cooperates with the first catheter clamping element 41 to clamp the catheter, or the second reset element 62 retracts into the fifth mounting element 44. The second catheter clamping element 61 is located in the placement element 45, and the first catheter clamping element 41 clamps the catheter. When the catheter is thinner, the second reset element 62 restores its deformation to support the second catheter clamping element 61 to adjust the radial dimension of the first catheter clamping element 41, and cooperates with the first catheter clamping element 41 to clamp the catheter. The fourth anti-slip element 63 prevents the catheter from sliding relative to the second catheter clamping element 61.

[0267] The technical effects of this embodiment are as follows:

[0268] The radial dimension of the catheter clamping unit can be adjusted using the second adjustment unit to fix catheters of different specifications. This makes it flexible and convenient to use, expands the application range of the catheter clamping unit, and further solves the problems of complex operation and limited use.

[0269] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
