Description

Technical Field

[0001] The utility model relates to the technical field of stoma appliances, and particularly to a fixing device for a stoma bag and a stoma bag. Background Art

[0002] The chassis of a stoma bag is an important part of the stoma bag. It directly adheres to the patient's stoma and is used to collect and store excrement. The design and material of the chassis have an important impact on the patient's comfort and nursing effect. The existing types of stoma bag chassis are one-piece chassis and two-piece chassis. The one-piece chassis is integrally formed with the stoma bag body and cannot be separated. The advantage of the one-piece chassis is that it is convenient to use and does not require additional operations, but once removed, it cannot be reused. The two-piece chassis can be separated from the stoma bag body. Generally, there is an adhesive on the chassis, and the chassis can be pasted around the patient's stoma. The two-piece chassis can be used multiple times, and the bag is installed when needed, reducing the economic burden of patient care.

[0003] However, there are many problems with the existing stoma bag chassis when it is fixed to the patient. The main problem is that the fixation is not firm. Since there is usually liquid flowing out around the stoma, the existing stoma bag chassis is often difficult to be firmly fixed on the patient, and it is easy to shift or fall off during use. Additional adhesive tape is needed for fixation. However, the adhesive tape used to reinforce the stoma bag chassis often cannot be fixed to the skin and the stoma bag chassis at the same time. There is still the problem of insecure fixation.

[0004] In view of this, the applicant has put forward this application after studying the existing technologies. Content of the Utility Model

[0027] Example 1. Consisting ofFigures 1 to 3 As shown in the figure, an embodiment of the present utility model provides a fixing device for a stoma bag, which includes a first adhesive patch 1 and a second adhesive patch 5 attached to the first adhesive patch 1.

[0028] The first adhesive patch 1 includes a water-absorbing glue layer 2 that can be adhered to the skin, a water-blocking layer 3 joined to the side of the water-absorbing glue layer 2 away from the skin, and a first sticky glue layer 4 joined to the side of the water-blocking layer 3 away from the water-absorbing glue layer 2. Preferably, the material of the first sticky glue layer 4 can be pressure-sensitive adhesive or hot-melt adhesive, etc., to obtain a better bonding effect with the second adhesive patch and avoid the separation of the two during long-term use.

[0029] The first adhesive patch 1 is provided with a stoma through-hole 9. On the side of the first sticky glue layer 4 away from the water-blocking layer 3, there is a first outer connecting part 10 surrounding the stoma through-hole 9 and a second outer connecting part 11 surrounding the first outer connecting part 10. Preferably, the first outer connecting part 10 is configured to be able to be attached to the stoma bag body or to a connecting bracket 8 (or: stoma disc, stoma chassis) used to connect the stoma bag body.

[0030] The second adhesive patch 5 is configured as an annular structure and is attached to the second outer connecting part 11. The second adhesive patch 5 extends outward from the second outer connecting part 11, and at least the part extending outward is provided with a second sticky glue layer 6 on the side facing the water-absorbing glue layer 2. Among them, at least part of the second sticky glue layer 6 is configured to be able to be adhered to the skin. Preferably, the water-absorbing ability of the water-absorbing glue layer 2 is stronger than that of the second sticky glue layer 6. The adhesiveness of the second sticky glue layer 6 is stronger than that of the water-absorbing glue layer 2.

[0031] A fixing device for a stoma bag of the present utility model is sleeved around the stoma by adhering the first adhesive patch 1, and while absorbing exudate, it is fixed. The part of the second adhesive patch 5 attached to the first adhesive patch 1 is fixed on the first adhesive patch 1 through the first sticky glue layer 4, and the part extending outward from the first adhesive patch 1 is adhered to the skin through the second sticky glue layer 6 to reinforce the first adhesive patch 1, so as to ensure that the first adhesive patch 1 is well fixed on both the first adhesive patch 1 and the skin, which has great practical significance.

[0032] On the basis of the above embodiment, in an optional embodiment of the present utility model, the second adhesive patch 5 includes a glue layer substrate 7. The second sticky glue layer 6 is attached to the side of the glue layer substrate 7 facing the water-absorbing glue layer 2. In this embodiment, the second sticky glue layer 6 and the glue layer substrate 7 have the same shape to completely cover the glue layer substrate 7.

[0033] The structure completely covered by the adhesive layer enables more convenient production and greatly reduces production costs. In addition, the second adhesive layer 6 and the water-proof layer 3 are adhesively fixed through the first adhesive layer 4, which has a better fixing effect and effectively avoids the separation of the two during use.

[0034] The material of the adhesive layer substrate 7 can be materials such as PU film, silk, non-woven fabric or polyester flannelette, which are softer and more ductile. They can not only bond better with the first adhesive layer 4 and have a stronger bonding effect, but also fit better on the skin.

[0035] In other embodiments, the second adhesive layer 6 can only cover the part of the adhesive layer substrate 7 extending outward from the first adhesive patch 1 to ensure the effect of fixing on the skin. The adhesive layer substrate 7 is fixed to the first adhesive patch 1 through the first adhesive layer 4. Specifically, the adhesion between the adhesive layer substrate 7 and the skin, and the adhesion between the adhesive layer substrate 7 and the water-proof layer 3 are respectively carried out through different adhesive layers, which can achieve a better adhesion effect and prevent separation between the two.

[0036] On the basis of the above embodiments, in an optional embodiment of the present utility model, the fixing device of the ostomy bag further includes a release sheet attached to the side of the water-absorbing adhesive layer 2 away from the water-proof layer 3.

[0037] Specifically, the release sheet and the separator can well prevent the water-absorbing adhesive layer 2 and the second adhesive layer 6 from adhering to other objects before use. Keep the adhesive surface clean and easy to store. Through the multi-piece separator, the separator can be torn off after the first adhesive patch 1 is adhesively fixed, so as to reinforce the first adhesive patch 1 through the second adhesive patch 5, which has good practical significance.

[0038] On the basis of the above embodiments, in an optional embodiment of the present utility model, the water-absorbing adhesive layer 2, the water-proof layer 3 and the first adhesive layer 4 have the same shape. Specifically, the same shape is convenient for production. In other embodiments, the covering area of the first adhesive layer 4 can be further set as required, and the embodiments of the present utility model do not make limitations in this regard.

[0039] Preferably, the outer edge shape of the first adhesive patch 1 and / or the second adhesive patch 5 can be circular, oval, square, rectangular, or triangular.
