Description

Technical Field

[0001] This utility model generally relates to the field of medical devices, and more specifically, to a fixed urinary catheter. Background Technology

[0002] In medicine, urinary catheterization involves inserting a catheter through the urethra into the bladder to drain urine. There are two types of catheterization: indwelling catheterization and intermittent catheterization. In indwelling catheterization, the catheter remains in place and must be changed regularly. In intermittent catheterization, the catheter is removed every 4-6 hours after the bladder is emptied. The advantages of indwelling catheterization include: preventing urine leakage and bed linen contamination due to patient non-compliance; securing the catheter quickly to prevent slippage; and facilitating comprehensive urine management, such as directing urine from patients with hepatitis or tumors into disposable drainage bags for centralized treatment and preventing iatrogenic cross-infection.

[0003] When urinary catheters and their accompanying urine bags are used in clinical care, especially balloon catheters, the limitations of internal fixation mean that the catheter and urine bag often move due to patient movement or other careless actions. This movement can easily aggravate the patient's pain. A common method of fixation is with medical tape, but this method is often insecure and prone to catheter displacement and loosening, still failing to prevent pain. This pain and discomfort can potentially cause trauma to the area in contact with the catheter, leading to infection and exacerbating existing wounds. This constitutes a significant physical and psychological harm to the patient. Utility Model Content

[0004] This application provides a fixed urinary catheter to solve the above-mentioned technical problems.

[0005] This application provides a fixed urinary catheter, including: a urinary catheter body, a buckle, and a fixing patch. The buckle is disposed on the external part of the urinary catheter body, and the bottom of the fixing patch is provided with adhesive. The fixing patch is applied to the patient's body by the adhesive, and the buckle and the fixing patch are detachably connected.

[0006] According to some embodiments of the present invention, the fixing patch includes an applicator, a mounting base, and an elastic ring. The mounting base is disposed on the applicator, and two mounting posts are provided protruding outward from the mounting base. The buckle is installed between the two mounting posts to restrict the planar movement of the catheter body. The elastic ring is sleeved on the two mounting posts to restrict the catheter body from detaching from the mounting base.

[0007] According to some embodiments of this utility model, the buckle is provided with circular holes corresponding to the mounting posts, and the buckle is used to limit the two mounting posts by respectively fitting them through the two circular holes.

[0008] According to some embodiments of this utility model, the buckle is provided with a U-shaped groove corresponding to the mounting post, and the buckle is limited by engaging the two mounting posts respectively through the two U-shaped grooves.

[0009] According to some embodiments of the present invention, the upper end of the mounting post is provided with a groove for preventing the elastic ring from disengaging.

[0010] According to some embodiments of this utility model, the elastic ring is made of elastic rubber.

[0011] According to some embodiments of this utility model, the mounting base and the mounting column are made of rigid plastic and are integrally molded.

[0012] According to some embodiments of the present invention, the patch is provided with multiple ventilation holes.

[0013] As can be seen from the above technical solution, the advantages and positive effects of this utility model for fixing a urinary catheter are as follows: This application uses a fixing patch to apply to the patient's body.

[0028] like Figure 1 and Figure 2 As shown in the illustration, an embodiment of a fixed urinary catheter includes: a catheter body 1, a buckle 2, and a fixing adhesive. The buckle 2 is located on the external part of the catheter body 1, and the fixing adhesive has an adhesive layer at its bottom. The fixing adhesive is applied to the patient's body using the adhesive, and the buckle 2 is detachably connected to the fixing adhesive. This application uses a fixing adhesive applied to the patient's body. Due to the flat adhesive surface and large adhesive area, the fixing adhesive is firmly connected to the patient's body. The buckle 2 is then detachably connected to the fixing adhesive, thus fixing the catheter body 1. The detachable connection facilitates the operation and replacement of the catheter body 1. The secure connection between the catheter body 1 and the fixing adhesive via the buckle 2 prevents catheter displacement and loosening, reducing pain and discomfort for the user.

[0029] like Figure 1 and Figure 2As shown, in some embodiments of this utility model, the fixing patch includes a dressing 30, a mounting base 31, and an elastic ring 32. The mounting base 31 is disposed on the dressing 30, and two mounting posts 33 are provided protruding outward from the mounting base 31. The buckle 2 is installed between the two mounting posts 33 to restrict the planar movement of the catheter body 1. The elastic ring 32 is sleeved on the two mounting posts 33 to restrict the catheter body 1 from detaching from the mounting base 31. In use, the dressing 30 is applied to the patient's body. Due to the flat surface and large adhesive area, the dressing is firmly attached to the patient's body. The buckle 2 is installed between the two mounting posts 33 to limit its movement, preventing it from moving in the plane. This fixes the catheter body 1 in the plane. To prevent the catheter body 1 from detaching from the mounting base 31 in the vertical direction, elastic rings 32 are fitted on the two mounting posts 33. The elastic rings 32 are tensioned on the two mounting posts 33 to restrict the buckle 2 from detaching from the mounting base 31, thus fixing the catheter body 1 in the vertical direction. The operation is simple and convenient.

[0030] like Figure 3 As shown, in some embodiments of this utility model, the buckle 2 is provided with circular holes 20 corresponding to the mounting posts 33. The buckle 2 is fitted onto the two mounting posts 33 through the two circular holes 20 for limiting its position. By fitting the buckle 2 onto the two mounting posts 33 through the two circular holes 20, the buckle 2 is limited at two points, preventing both planar movement and rotation, resulting in a good fixing effect.

[0031] like Figure 4 As shown, in some other embodiments of this utility model, the buckle 2 is provided with a U-shaped groove 21 corresponding to the mounting post 33. The buckle 2 is respectively engaged with the two mounting posts 33 through the two U-shaped grooves 21 for limiting its position. By engaging with the two mounting posts 33 through the two U-shaped grooves 21, the buckle 2 is limited at two points, preventing both planar movement and rotation, resulting in a good fixing effect. Designs similar to the above should be included in the protection scope of this application.

[0032] like Figure 2 As shown, in some embodiments of this utility model, the upper end of the mounting post 33 is provided with a groove 330 for preventing the elastic ring 32 from disengaging. During installation, the elastic ring 32 is inserted into the groove to prevent it from disengaging.

[0033] According to some embodiments of this utility model, the elastic ring 32 is made of elastic rubber. Elastic rubber has good elasticity, meets a certain range of stretching adjustment, and has good recovery. In use, the elastic ring 32 is enlarged and fitted onto the two mounting posts 33. The elastic ring 32 contracts and tightens on the two mounting posts 33 to prevent it from falling off.

[0034] In some embodiments of this utility model, the mounting base 31 and the mounting post 33 are made of rigid plastic and are integrally molded. The rigid plastic used in the mounting base 31 and mounting post 33 makes them less prone to deformation during use, provides good strength, and the integral molding reduces the number of parts and assembly, facilitating injection molding and lowering manufacturing costs.

[0035] like Figure 1 As shown, in some embodiments of this utility model, the patch 30 is provided with a plurality of ventilation holes 300. The ventilation holes 300 can effectively improve the breathability of the patch 30 and reduce the discomfort of long-term application by the patient.
