[0030] The embodiment of the utility model provides a planar shapeable hydrocolloid stoma base plate and a stoma bag assembly. The stoma base plate can be suitable for stomas of different sizes and has a wide range of applications.

[0031] Combine the following Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0032] Embodiment 1:

[0033] The flat, shapeable hydrocolloid stoma base plate 100 provided by the utility model comprises a release film 2, an adhesive layer component (such as Figure 1 The adhesive layer assembly of this embodiment includes a plastic hydrocolloid layer 1, an outer colloid layer 3) and a barrier film 4, wherein: the adhesive layer assembly includes a plastic hydrocolloid layer 1, a release film 2 is attached to one side of the plastic hydrocolloid layer 1, and the barrier film 4 is connected to the other side of the adhesive layer assembly, and the barrier film 4 is used to connect with a plastic part 5 fixed on the ostomy bag; a drainage port 101 for the stoma to pass through is provided on the plastic hydrocolloid layer 1, and the plastic hydrocolloid layer 1 can be deformed under the action of external tearing force, thereby changing the size of the drainage port 101.

[0034] See also Figure 3 and Figure 4 As shown, the plastic part 5 is used to connect the stoma base plate 100 and the stoma bag. The plastic part 5 is usually fixed to the stoma bag by a snap-fit ​​method. As this is an existing mature technology, it will not be described in detail here.

[0035] Specifically, the plastic part 5 is fixed on the barrier film 4 by hot melting or the like. The barrier film 4 is a conventional structure of an existing stoma base plate, and its main function is to fix the plastic part 5, and its material is not described in detail here.

[0036] The planar shapeable hydrocolloid stoma base plate 100 of the present embodiment has a plastic part 5 fixed on the barrier film 4 by hot melting or the like, and the stoma base plate 100 and the stoma bag are connected by the plastic part 5. A drainage port 101 for the stoma to pass through is provided on the shapeable hydrocolloid layer 1. According to the different outer diameters of the stoma, the size of the drainage port 101 can be changed by tearing the shapeable hydrocolloid layer 1 by hand. Since the shapeable hydrocolloid layer 1 has a certain plastic deformability, it can allow stomas of different calibers to pass through. After the stoma passes through, it can be adhered to the outer wall of the stoma by the elastic rebound of the shapeable hydrocolloid layer 1 to prevent leakage of drainage fluid. After tearing off the release film 2, the stoma base plate 100 can be attached to the skin.

[0037] The stoma base plate 100 can be applied to stomas of different sizes and has a wide range of applications.

[0038] As an optional embodiment, the shapeable hydrocolloid layer 1 is a structural layer made of thermoplastic elastomer.

[0039] The above-mentioned plastic hydrocolloid layer 1 is a layered structure made of hydrocolloid. Specifically, in the prior art, it is usually made by high-temperature stirring using thermoplastic elastomer (sis, i.e. styrene-isoprene-styrene block copolymer), saturated linear polymer (such as polyisobutylene), thickener, and tackifier.

[0040] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the stoma base plate 100 further includes an outer colloid layer 3 , which is adhered and fixed to the plastic hydrocolloid layer 1 , and a barrier film 4 is attached to a side of the outer colloid layer 3 that is away from the plastic hydrocolloid layer 1 .

[0041] The outer colloid layer 3 is a conventional adhesive layer in the prior art, and the outer colloid layer 3 does not need to be torn by hand to deform. The function of the outer colloid layer 3 is to adhere and fix the plastic hydrocolloid layer 1 and fix the barrier film 4. When the plastic hydrocolloid layer 1 is torn, the shape and size of the drainage port 101 change, but the outer colloid layer 3 does not change, which is convenient for stably fixing the barrier film 4 and the plastic part 5, thereby facilitating the stable fixation of the stoma base plate 100 and the stoma bag.

[0042] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the drainage port 101 is located at the center of the plastic hydrocolloid layer 1 .

[0043] The above structure can improve the stability of the structure after the stoma passes through the drainage port 101 , and the drainage port 101 is located at the center of the plastic hydrocolloid layer 1 , so the drainage port 101 is not easily torn to the edge of the plastic hydrocolloid layer 1 .

[0044] As an alternative embodiment, see Figure 1 As shown, a protrusion 11 is provided on the side of the plastic hydrocolloid layer 1 facing away from the release film 2 . The protrusion 11 is located in the middle of the plastic hydrocolloid layer 1 , and the drainage port 101 is located on the protrusion 11 .

[0045] The above structure can increase the thickness of the drainage port 101, ensuring that the drainage port 101 is cracked to the outer edge of the plastic hydrocolloid layer 1 when torn by external force, thereby improving the structural stability and prolonging the time for absorbing exudate.

[0046] As an alternative embodiment, see Figure 1 As shown, the outer colloid layer 3 is an annular structure layer, and the outer colloid layer 3 is coaxially arranged with the plastic hydrocolloid layer 1. Figure 1 As shown, the outer colloid layer 3 is provided with a clamping hole 301 , and when the outer colloid layer 3 is adhered to the plastic hydrocolloid layer 1 , the protrusion 11 passes through the clamping hole 301 .

[0047] The matching structure of the clamping hole 301 and the protrusion 11 facilitates positioning of the outer colloid layer 3 and the plastic hydrocolloid layer 1, prevents the plastic hydrocolloid layer 1 and the outer colloid layer 3 from shifting relative to each other, and improves the stability of the structure.

[0048] As an optional embodiment, the release film 2 is a PET film.

[0049] As an alternative embodiment, see Figure 1 , Figure 3 and Figure 4 As shown, the barrier film 4 is an annular structure, which is convenient for fixing the plastic part 5.

[0050] The planar plastic hydrocolloid stoma base plate 100 of the present embodiment can change the size of the drainage port 101 by tearing the plastic hydrocolloid layer 1 by hand. Since the plastic hydrocolloid layer 1 has a certain plastic deformability, it can allow stomas of different calibers to pass through. Since the plastic hydrocolloid has a certain plastic deformability and viscosity, after the stoma passes through, the plastic hydrocolloid layer 1 can be adhered to the outer wall of the stoma by pinching and pressing to prevent drainage fluid leakage.

[0051] See also Figure 3 As shown, Figure 3 FIG. 1 shows the structure of the planar shapeable hydrocolloid stoma base plate 100 in the initial state. In the initial state, the drainage port 101 is circular. If the outer diameter of the stoma is larger than the inner diameter of the drainage port 101, see Figure 4 As shown, Figure 4 The dotted circle in the figure represents the initial state of the drainage port 101. The shape and size of the drainage port 101 are changed by tearing the drainage part of the plastic hydrocolloid layer 1. After the stoma passes through the drainage port 101, the plastic hydrocolloid layer 1 is adhered to the outer wall of the stoma by pinching and pressing, etc., to prevent leakage of drainage fluid, which is easy to operate.

[0052] Embodiment 2:

[0053] This embodiment provides an ostomy bag assembly, comprising an ostomy bag, a plastic part 5 and the above-mentioned flat shapeable hydrocolloid ostomy base plate 100, wherein the plastic part 5 fixes the ostomy base plate 100 to the ostomy bag. The above-mentioned ostomy bag assembly, due to the above-mentioned ostomy base plate 100, can improve the scope of application.

[0054] The ostomy bag assembly can reduce drainage fluid leakage, improve the quality of life of ostomy patients, and reduce nursing costs.

[0055] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
