[0035] Implementation case 1:

[0036] like Figure 1 The figure shows the overall structure of a gauze block for fixing the skin of a hemodialysis catheter according to the utility model.

[0037] like Figure 1 to Figure 2 As shown, a gauze block for fixing the hemodialysis catheter to the skin comprises a gauze block cover 1 and a connecting belt 2 connected to the outside of the gauze block cover 1. The gauze block cover 1 can be used to cover the hemodialysis catheter 4 to wrap the hemodialysis catheter 4. The connecting belt 2 can be wrapped around the outside of the gauze block cover 1 to tie the hemodialysis catheter 4 tightly on the gauze block cover 1 so that the hemodialysis catheter 4 is tightly wrapped to prevent infection.

[0038] The gauze block cover 1 is configured with an opening 11 at one end and a closed end at the other end, so that the hemodialysis catheter 4 can be placed in the gauze block cover 1 at the opening 11 at one end of the gauze block cover 1 for wrapping. Preferably, the gauze block cover 1 is a bag-like structure sewn from gauze, which has an opening 11 at one end and can be flexibly deformed, so that the connecting belt 2 is wrapped around the outside of the gauze block cover 1 to wrap and fix the hemodialysis catheter 4.

[0039] The two opposite sides (the two sides with larger areas) of the connecting belt 2 are respectively configured as a smooth surface on one side and an adhesive surface on the other side. When the connecting belt 2 is wrapped around the gauze block cover 1, the gauze block cover 1 can be tightly wrapped by adhesion through the adhesive surface, or the connecting belt 2 can also be adhered to the patient's skin through the adhesive surface.

[0040] It should be noted that, in some embodiments, the length of the connecting belt 2 is long enough, and after the connecting belt 2 is wrapped around the gauze block sleeve 1, the remaining part can still adhere the gauze block sleeve 1 to the patient, so that the hemodialysis catheter 4 can be fixed on the patient. Alternatively, in some other embodiments, the connecting belt 2 may not be provided with an adhesive surface, and the connecting belt 2 can be used to bind and tighten the gauze block sleeve 1.

[0041] Specifically, in this embodiment, the connecting belt 2 includes a first connecting belt 21 and a second connecting belt 22, and the first connecting belt 21 and the second connecting belt 22 are both configured to have a smooth surface on one side and an adhesive surface on the other side, and the first connecting belt 21 and the second connecting belt 22 are symmetrically arranged on both sides of the yarn block sleeve 1. Figure 2 As shown, the first connecting belt 21 is arranged on the left side of the yarn block cover 1, and the second connecting belt 22 is arranged on the right side of the yarn block cover 1. Two first connecting belts 21 and two second connecting belts 22 are arranged, and are symmetrical to each other on both sides of the yarn block cover 1.

[0042] Furthermore, release paper (not shown) is provided on the adhesive surface of the first connecting tape 21 and the second connecting tape 22. When the first connecting tape 21 and the second connecting tape 22 are used, the release paper can be torn off on the adhesive surface of the connecting tape 2 for use.

[0043] like Figure 2 As shown, when in use, the hemodialysis catheter 4 is inserted into the gauze block cover 1 from the opening 11 at one end of the gauze block cover 1, the first connecting belt 21 on the left side of the gauze block cover 1 can be wrapped to the right, and the second connecting belt 22 on the right side of the gauze block cover 1 can be wrapped to the left side of the gauze block cover 1, so that the hemodialysis catheter 4 can be tightly wrapped in the gauze block cover 1, and the excess parts of the first connecting belt 21 and the second connecting belt 22 can be adhered to the patient's skin, so that the gauze block cover 1 is fixed on the patient, so that the hemodialysis catheter 4 is fixed.

[0044] Or, if Figure 3 , Figure 4 As shown, only one connecting belt 2 can be provided, and the hemodialysis catheter 4 can be fixed in the gauze block cover 1 by winding the connecting belt 2 multiple times on the gauze block cover 1 to prevent infection. A fixing sleeve structure for fixing the structure can be provided to fix it on the patient.

[0045] In this embodiment, the hemodialysis catheter skin fixation convenient gauze block only needs to set the gauze block cover 1 and the connecting belt 2 to complete the wrapping and fixation of the hemodialysis catheter 4, which has a simple structure and is easy to operate.

[0046] Embodiment 2:

[0047] refer to Figure 5 , Figure 6This embodiment provides another convenient gauze block for fixing the skin of the hemodialysis catheter. The difference between this embodiment and the first embodiment is that: in this embodiment, a separation layer 3 is also provided on the gauze block cover 1, and the hemodialysis catheter 4 is generally provided with two, a blue catheter 41 and a red catheter 42. In this embodiment, the gauze block cover 1 is provided with a separation layer 3 so that the hemodialysis catheter 4 can be separated in the gauze block cover 1 to prevent cross infection.

[0048] like Figure 5 As shown, in this embodiment, the partition layer 3 is arranged in the middle of the yarn block cover 1, and the yarn block cover 1 is divided into two cavities 12 on the left and right, so that the blue catheter 41 and the red catheter 42 can be placed in the two cavities 12 respectively to prevent cross infection. Alternatively, in some other embodiments, the partition layer 3 can also divide the yarn block cover 1 into two cavities 12 on the top and bottom.

[0049] Preferably, the partition layer 3 is made of an antibacterial material, such as antibacterial plastic, and the partition layer 3 can be a roughly rectangular structure, with sterile gauze sewn on both sides of the partition layer 3 to form two cavities 12, i.e., the structure of the yarn block cover 1. Alternatively, in some other embodiments, the partition layer 3 can also be made of ordinary plastic, and an antibacterial layer can be sprayed on its surface to make the yarn block cover 1 antibacterial.

[0050] Similar to the first embodiment, when the convenient gauze block for fixing the hemodialysis catheter to the skin is used in this embodiment, the hemodialysis catheter 4 is inserted into the gauze block cover 1 from the opening 11 at one end of the gauze block cover 1, wherein the blue catheter 41 is placed in the left cavity 12, and the red catheter 42 is placed in the right cavity 12. The first connecting belt 21 on the left side of the gauze block cover 1 can be wrapped to the right, and the second connecting belt 22 on the right side of the gauze block cover 1 can be wrapped to the left side of the gauze block cover 1. Because the left cavity 12 and the right cavity 12 of the partition layer 3 are both sewn with sterile gauze and can be flexibly deformed, the connecting belt 2 can wrap the hemodialysis catheter 4 tightly around the gauze block cover 1, and the excess parts of the first connecting belt 21 and the second connecting belt 22 can be fixed on the patient to complete the wrapping and fixation.

[0051] In this implementation case, the structure of the connecting belt 2 is consistent with that in the first embodiment and will not be described again here.

[0052] In some embodiments, an ultraviolet lamp structure may be further provided on the partition layer 3. When the ultraviolet lamp structure is provided on the partition layer 3, it can irradiate the two cavities 12, thereby reducing the risk of infection of the blue catheter 41 and the red catheter 42 in the cavity 12.

[0053] In some embodiments, a waterproof film is also provided on the gauze block cover 1. Preferably, the waterproof film can be provided in the cavity 12 where the hemodialysis catheter 4 is placed, so as to prevent the hemodialysis catheter 4 from being contaminated by sweat when the patient sweats.

[0054] Alternatively, in some embodiments, the separation layer 3 may not be provided, and an ultraviolet lamp structure may be provided at the end of the gauze block cover 1 without the opening 11. The ultraviolet lamp structure may be used to irradiate the inside of the gauze block cover 1, thereby reducing the risk of infection of the hemodialysis catheter 4 in the gauze block cover 1.

[0055] The utility model discloses a convenient gauze block for fixing the skin of a hemodialysis catheter, which has a simple structure and can be used for wrapping and fixing the hemodialysis catheter by providing a gauze block cover and a connecting belt. After the hemodialysis catheter with the connecting belt is wrapped in the gauze block cover, it can be fixed by adhering to the skin through the connecting belt. The utility model has a good feeling when used and is convenient for doctors to operate and use. A partition layer and an ultraviolet lamp structure are also provided, so that infection can be reduced when the hemodialysis catheter is wrapped.

[0056] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
