Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical catheter fixing patch. Background Art

[0002] In the prior art, a urinary catheter is generally fixed by a combination of a hydrocolloid dressing and a transparent dressing. The hydrocolloid dressing is attached under the urinary catheter to protect the skin, and the transparent dressing is used to fix the urinary catheter.

[0003] When in use, it is necessary to prepare hydrocolloid dressings and transparent dressings of corresponding sizes each time, so it lacks convenience. In addition, for children and other patients, when twisting, moving, or turning over, the existing catheter fixing method is easy to curl, fall off, or shift, thereby pulling the urethra and easily causing urethral damage. When the hydrocolloid dressing shifts, it will lose its protective effect on the child's skin. When the catheter falls off, it will cause the catheter to rotate the sampling port, compressing the patient's skin, which may cause pressure sores and reduce the patient's comfort. Utility Model Content

[0004] The utility model aims to solve the problems of poor fixation effect, damage to patient's skin and poor convenience caused by the medical catheter falling off or shifting.

[0005] To solve the above problems, the utility model proposes a medical catheter fixing patch, comprising a main body and a catheter fixing assembly arranged on the main body; the catheter fixing assembly comprises a fixing patch strip arranged in the middle area of ​​the main body and at least two annular fixing buckles for fixing the catheter.

[0006] Furthermore, the fixing hook and loop fastener is provided with a first fixing surface and a second fixing surface, and the first fixing surface and the second fixing surface are located on both sides of the fixing strip. The catheter fixing assembly also includes a mounting layer at least partially disposed between the fixing hook and loop fastener and the body, and the mounting layer is provided with a first mounting surface for connecting to the first fixing surface, and a second mounting surface for connecting to the second fixing surface.

[0007] Preferably, the fixing hook and loop fastener is oval, and the fixing strip is long. The radial directions of the two fixing hook and loop fasteners form an angle of 85-95° with each other, and the angle between the radial direction of the fixing hook and loop fasteners and the length direction of the fixing strip is 40-50°. Alternatively, the radial directions of the two fixing hook and loop fasteners form an angle of 0-5° with each other, and the angle between the radial direction of the fixing hook and loop fasteners and the length direction of the fixing strip is 85-95°.

[0008] Preferably, the first fixing surface and the second fixing surface are both arranged at the edge of the installation layer. The area of ​​the installation layer is smaller than the area of ​​the body. The fixing strip is provided with a buffer layer for buffering the pressure of the catheter.

[0009] Furthermore, the main body includes a waterproof layer, a breathable layer and an adhesive layer for being adhered to a body surface, which are arranged in sequence.

[0010] Compared with the prior art, the technical solution of the utility model has the following beneficial effects: it can better fix the medical catheter, prevent the catheter from falling off or shifting, protect the patient's skin, and is convenient and quick to use.

[0023] Furthermore, the body 1 includes a waterproof layer 11, a breathable layer 12 and an adhesive layer 13 arranged in sequence. Among them, the adhesive layer 13 is used to stick the catheter fixing patch on the body surface. In a specific embodiment, the waterproof layer 11 is preferably made of polyurethane material, the breathable layer 12 is preferably made of medical non-woven fabric, and the adhesive layer 13 is preferably made of pressure-sensitive adhesive, so that while fixing the catheter, it can reduce skin damage to the patient and improve comfort.

[0024] Furthermore, the catheter fixing assembly 2 includes a fixing strip 23 provided in the middle area of ​​the body 1. The fixing strip 23 is preferably in the shape of a long strip and is arranged along the length direction of the catheter for fixing the catheter. The fixing strip 23 may also be square, polygonal, circular, elliptical, etc. Preferably, a buffer layer is provided on the fixing strip 23, which can buffer the catheter pressure in scenes such as clinical sampling and bladder irrigation, thereby further protecting the patient's skin. In a specific embodiment, the buffer layer may be a hydrocolloid dressing or a foam dressing, wherein the hydrocolloid dressing is composed of materials such as high moisture content and a variety of water-soluble high molecular weight materials, and the foam dressing includes loose foam materials and material fiber meshes. Preferably, the buffer layer is a foam dressing, thereby improving the waterproof performance, improving the air permeability, and making the structure of the catheter fixing part lighter.

[0026] Further, the catheter fixing assembly 2 further includes a mounting layer 21, and the mounting layer 21 is at least partially disposed between the fixing hook and loop 22 and the mounting layer 21. Preferably, the area of ​​the mounting layer 21 is smaller than the area of ​​the body 1, and is not smaller than the area of ​​the fixing hook and loop 22. The mounting layer 21 may be elliptical, rectangular, or polygonal. Preferably, the mounting layer 21 is elliptical to further prevent curling, and the fixing hook and loop 22 is disposed on the surface of the mounting layer 21. Preferably, the diameter of the fixing hook and loop 22 is smaller than the diameter of the mounting layer 21.

[0027] Furthermore, the fixing hook and loop 22 is provided with a first fixing surface 221 and a second fixing surface 222, and the first fixing surface 221 and the second fixing surface 222 are located on both sides of the fixing strip 23. In addition, the mounting layer 21 is provided with a first mounting surface 211 for connecting with the first fixing surface 221, and a second mounting surface 212 for connecting with the second fixing surface 222.

[0028] In a specific embodiment, the first fixing surface 221 is fixed to the first mounting surface 211 by means of Velcro, adhesive or sewing. Preferably, it is fixed by Velcro, that is, the first fixing surface 221 is a hook surface, and the first mounting surface 211 is a fur surface, which are pasted to each other to fix one end of the fixed Velcro 22. Preferably, the second fixing surface 222 and the second mounting surface 212 are pasted to each other, one of which is a fur surface and the other is a hook surface, to fix the other end of the fixed Velcro 22. In another specific embodiment, the second fixing surface 222 and / or the second mounting surface 212 surface may also be provided with an adhesive, and preferably, a release film that is convenient to use is also provided to facilitate pasting. In addition, a snap-on buckle in the prior art may also be provided on the second fixing surface 222 and the second mounting surface 212 to achieve a detachable connection, so as to facilitate use.

[0029] Furthermore, the number of the fixing hooks 22 is at least two, and the two fixing hooks 22 can be fixed to the body 1 by crossing or sleeve-arranging each other.

For example, the radial directions of the two fixing buckles 22 are perpendicular to each other, and the radial directions of the two fixing buckles 22 are both set at an angle of 45° to the length direction of the fixing strip 23. Through multiple fixations, the catheter can be better reinforced.

[0031] In another specific embodiment, the radial directions of the two fixing buckles 22 form an angle of 0 to 5° with each other, and the angle between the radial direction of the fixing buckle 22 and the length direction of the fixing strip 23 is 85 to 95°. For example, the radial directions of the two fixing buckles 22 are parallel to each other, and the radial directions of the two fixing buckles 22 are perpendicular to the length direction of the fixing strip 23.

[0032] When in use, the main body 1 is pasted on the body surface to fix the catheter on the surface of the fixing strip 23, and then the two fixing buckles 22 are crossed or wrapped around the catheter to fix the catheter and prevent it from falling off or shifting.
