[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figures 1 to 4 As shown, a medical catheter fixing patch includes a dressing layer 1, a retaining layer 2 and a fastening belt 3. A release paper (not shown) is provided on the bottom side of the dressing layer 1, which can be used to adhere the dressing layer 1 to the human skin after removing the release paper. The retaining layer 2 is arranged on the side of the dressing layer 1 away from the release paper, that is, arranged on the upper side of the dressing layer 1. One side of the fastening belt 3 is connected to the retaining layer 2, for example, this side can be fixedly connected to the retaining layer 2 by sewing to form a connecting area 31, and an opening 30 is provided on the fastening belt 3 near its connecting area 31. The other side of the fastening belt 3 is bent and passes through the opening 30 to form a fastening ring 300, and is tightened to wrap the catheter therein. Then, after passing through the opening 30, at least a portion of the fastening belt 3 located outside the fastening ring 300 and away from its connecting area 31 is adhered to the retaining layer 2.

[0028] In the present invention, firstly, the release paper is removed and the dressing layer 1 is adhered to the human skin, the catheter is placed on the upper end surface of the fastening belt 3 and on the side close to the opening 30, the other side of the fastening belt 3 is operated to separate it from the retaining layer 2 and curl it to the other side, and then it is extended into the opening 30 to form a fastening ring 300 to wrap the catheter, and the side of the fastening belt 3 extending out of the opening 30 is pulled to make the fastening ring 300 tightly fit and wrap the catheter, and then this side is adhered to the retaining layer 2 to complete the positioning of the side and ensure the stability of the state of the fastening ring 300, so that the catheter can be stably positioned and fixed.

[0029] In the present application, only the fastening belt 3 is provided on the shape-retaining layer 2, and only the fastening belt 3 is operated to pass through the opening 30 to complete the fixation of the catheter. On the one hand, the catheter is fixed only by the fastening belt 3, so the parts of the medical catheter fixing patch are relatively few and the structure is simpler. On the other hand, the fastening ring 300 formed by the fastening belt 3 can completely wrap the entire outer wall of the catheter, and the entire catheter is located in the fastening ring 300. There is no gap on the side of the catheter, which has better wrapping stability. On the other hand, the size of the fastening ring 300 is based on the length of one side of the fastening belt 3 passing through the opening 30. The size of the fastening ring 300 can be easily and quickly adjusted according to the diameter of the catheter, and can be suitable for the fixation of catheters of different diameters.

[0030] More specifically, the fastening belt 3 includes a belt body 32 which is connected to the connecting area 31 and can be relatively movable. The opening 30 is formed on one side of the belt body 32 close to the connecting area 31, and the side of the belt body 32 adjacent to the shape-retaining layer 2 is connected to the shape-retaining layer 2 by Velcro 4, that is, the lower side of the belt body 32 is connected to the shape-retaining layer 2 by Velcro 4. Based on this design, when the fastening belt 3 is not in use, one side of the fastening belt 3 is sewn and connected, and the other side is adhered to the shape-retaining layer 2 by Velcro 4 and is fixed on the shape-retaining layer 2 as a whole. When the fastening belt 3 is used, after the catheter is positioned by the fastening ring 300, since the belt body 32 is bent and passes through the opening 30, the shape-retaining layer 2 is still adjacent to the shape-retaining layer 2 and is fixed, it is only necessary to set Velcro 4 between one side of the belt body 32 and the shape-retaining layer 2. The setting method is simple, and it is in a fitted state whether in use or not, and there will be no warping or the like.

[0031] In one embodiment of the utility model, the shape-retaining layer 2 is made of non-woven fabric with good air permeability. A hook surface 41 of the Velcro 4 is provided on its upper side, and a matching fur surface 42 is provided on the belt body 32. The fur surface 42 has better bending performance than the hook surface 41, making it easier for the belt body to bend and pass through the opening 30.

[0032] In addition, in another embodiment of the utility model, the shape-retaining layer 2 can be entirely set as the hook surface 41 of the Velcro, and the belt body 32 is provided with a matching fur surface 42, and the shape-retaining feature of the dressing layer 1 is simultaneously achieved by utilizing the hook surface 41 of the Velcro.

[0033] More specifically, in order to facilitate one end of the belt body 32 to pass through the opening 30 smoothly, the belt body 32 includes an integrally formed wide portion 321 and a narrow portion 322. The wide portion 321 is connected to the connecting area 31 and connected to the shape-retaining layer 2 for forming the opening 30. The narrow portion 322 is slightly smaller in width to facilitate passing through the opening 30.

[0034] The length of the wide portion 321 is less than 1 / 4 of the tightened fixing ring 300, which can ensure that the wide portion 321 is as small as possible while providing a suitable molding position for the opening 30. The narrow portion 322 located outside the tightened fixing ring 300 is in contact with the shape-retaining layer 2, that is, the rough surface 42 of the Velcro 4 has a larger length, which can form a fit at the root position of the outside after the fastening ring 300 is formed, so that the fastening ring 300 can be positioned more firmly to prevent the fastening ring 300 from shaking and causing the catheter to shake.

[0035] Furthermore, the opening 30 is disposed at the middle position of the wide portion 321 , which can ensure that the pulling force (pressure) of the wide portion 321 and the narrow portion 322 on the catheter is located at the middle position of the fastening ring 300 .

[0036] Preferably, the width of the opening 30 is 2 / 3-4 / 5 of the width of the wide portion 321, and the width of the narrow portion 322 is 4 / 5-5 / 6 of the width of the opening 30. On the basis of ensuring that the narrow portion 322 can smoothly pass through the opening 30, the effective area between the fastening ring 300 and the catheter is expanded as much as possible. On the one hand, greater contact can ensure better stability without sliding or twisting, and on the other hand, it can reduce the pressure on the catheter.

[0037] An adhesive layer 33 is provided on the fastening belt 3 near the opening 30, and a release paper is provided on the adhesive layer 33. When in use, the release paper can be removed and the catheter can be first adhered to the adhesive layer 33 to ensure that the position of the catheter is relatively fixed, thereby avoiding the phenomenon of the catheter shifting when operating the fastening belt 3, which is more convenient to operate.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
