Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, this embodiment provides a gastrostomy fixation patch, including a stoma patch 1, and the stoma patch 1 includes: an upper patch layer 2 and a lower patch layer 3. Installation slits 5 are opened at one side end of both the upper patch layer 2 and the lower patch layer 3. A movable collar 201 is installed on the lower surface of the upper patch layer 2. An extension backing plate 204 is arranged inside the upper patch layer 2 at the upper end of the movable collar 201. The extension backing plate 204 is fixedly connected to the movable collar 201. A clamping groove 202 is opened inside the lower end of the movable collar 201. A positioning collar 302 is installed on the upper surface of the lower patch layer 3 corresponding to the position of the movable collar 201. The inner diameter dimension length of the movable collar 201 is greater than the outer diameter dimension length of the positioning collar 302. An installation clamping block 303 is installed on the outer side of the upper end of the positioning collar 302. The installation clamping block 303 is clamped with the clamping groove 202. A reinforcement gasket 304 is arranged inside the lower patch layer 3 at the lower end of the positioning collar 302. The movable collar 201, the extension backing plate 204 and the reinforcement gasket 304 are all made of hard material components. The positioning collar 302 is fixedly connected to the reinforcement gasket 304. The provided installation slit 5 extends through to one side end of the movable collar 201 and the positioning collar 302, and can be used for the installation of a catheter.

[0024] As Figures 2-3 shown, in this embodiment, a strap mounting block 205 is installed through the upper patch layer 2 on the upper surface of the extension backing plate 204. A through hole is opened inside the strap mounting block 205. A catheter clamping groove 4 is arranged above the upper patch layer 2. Straps 6 are installed inside the strap mounting block 205 at both ends of the catheter clamping groove 4. The straps 6 are fixedly connected to the catheter clamping groove 4. A upper adhesive layer 203 is arranged on the lower surface of the upper patch layer 2 below the extension backing plate 204. A lower adhesive layer 301 is arranged on the upper surface of the lower patch layer 3 on the side far from the upper adhesive layer 203.

The upper adhesive layer 203 and the lower adhesive layer 301 are adhesively fixed.

[0025] The working principle of the present utility model is as follows: When in use, the lower adhesive layer 3 is integrally aligned with the position of the stoma. After the installation seam 5 at the side end of the lower adhesive layer 3 is integrally lifted outward and then sleeved on the outer side of the pipeline, the reinforcing gasket ring 304 will integrally cover the position above the stoma for support. At the same time, the positioning collar 302 provided will ensure the outer protection of the pipeline. After the lower adhesive layer 3 is integrally adhered to the outer side of the skin, the upper adhesive layer 2 is integrally lifted through the position of the installation seam 5 and sleeved on the outer side of the pipeline. First, after the catheter card slot 4 is aligned with the position of the strap mounting block 205, the strap 6 is passed through the inside of the strap mounting block 205. Then, the movable collar 201 below the upper adhesive layer 2 is integrally pressed on the outer side of the positioning collar 302, so that the card slot 202 is integrally stuck on the outer side of the installation card block 303. By rotating the movable collar 201 on the outer side of the positioning collar 302, when the position of the upper adhesive layer 203 is integrally aligned with the position of the lower adhesive layer 301, the release paper is torn off and then the upper adhesive layer 2 and the lower adhesive layer 3 are fixed. After the pipeline is integrally pressed into the catheter card slot 4, the strap 6 is integrally bound on the outer side of the catheter card slot 4, which can ensure the binding of the pipeline.
