Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing equipment, in particular to an ostomy chassis and an ostomy bag assembly. Background Art

[0002] When a patient suffers from bladder cancer or colorectal cancer, a common medical treatment is to perform urinary tract or intestinal diversion surgery on the patient, that is, to make an artificial stoma in the patient's abdomen, connect the patient's ureter or intestine to the stoma, and use a stoma bag device to collect urine or feces outside the body.

[0003] The ostomy bag device is generally divided into two parts: the stoma base plate and the stoma bag. The bottom of the stoma base plate has adhesive and is attached around the stoma. The stoma bag is connected to the base plate, and the patient's urine or feces can be discharged into the stoma bag through the stoma for collection, and then the stoma bag can be processed.

[0004] The stoma base plate needs to be adhered around the patient's stoma for a long time. The adhesive is generally made of hydrocolloid or acrylic adhesive material. Long-term use can cause skin itching, allergies, and even inflammation.

[0005] As a new type of adhesive dressing, silicone gel has good safety, extremely low sensitization rate, and the adhesive surface does not transfer and is therefore easy to tear off; however, silicone gel itself is not sticky enough and its adhesion is not enough to hang the ostomy bag and its contents.

[0006] Therefore, if traditional colloidal materials and new silicone gel materials can be designed and used in combination, fully utilizing the viscosity and adhesion of traditional colloidal materials while utilizing the safety and skin-friendliness of silicone gel, it will greatly reduce damage to the patient's skin and improve the patient's experience. Utility Model Content

[0007] Therefore, the technical problem to be solved by the utility model is that the traditional stoma bag arrangement method easily causes discomfort to the skin around the stoma of the patient, which is not conducive to the patient's recovery.

[0009] Optionally, the first colloid is medical hydrocolloid or medical acrylic glue, and the second colloid is medical silicone gel.

[0010] Optionally, the viscosity of the first colloid is greater than the viscosity of the second colloid.

[0011] Optionally, a shape of the second adhesive area matches a shape of the first adhesive area.

[0012] Optionally, the second adhesive area is distributed adjacent to the first adhesive area.

[0013] Optionally, the second adhesive area is provided with a cutting mark, and the cutting mark is constructed to facilitate manual cutting of a stoma hole suitable for stoma penetration; alternatively, the cutting mark may extend from the second adhesive area to the first adhesive area.

[0014] Optionally, the cutting mark is a plurality of concentrically distributed circular coils with different diameters; or, the cutting mark is a slit-shaped notch located at the center of the second adhesive area.

[0015] Optionally, a through hole is provided at the center of the second adhesive area, and a diameter of the through hole is smaller than an outer diameter of the stoma.

[0016] Optionally, the first adhesive area and the second adhesive area are provided on the same substrate; or, the first adhesive area and the second adhesive area are provided on different substrates respectively, and the first adhesive area and the second adhesive area are connected together by splicing the substrates.

[0017] The utility model also provides an ostomy bag assembly, comprising the ostomy bottom plate mentioned above.

[0018] The technical solution provided by the utility model has the following advantages:

[0019] The stoma base provided by the utility model is used to be attached to the side of the patient's stoma and is suitable for use with a stoma bag.

[0026] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0029] The utility model provides a stoma base plate 100, which is used to be attached to the periphery of a patient's stoma and is suitable for being used in conjunction with an ostomy bag body 200.

[0030] Specifically, see Figure 1 and Figure 2The stoma base plate 100 has an adhesive surface that fits the human skin, and the adhesive surface includes a first adhesive area 1 and a second adhesive area 2. The first adhesive area 1 is arranged around the outer periphery of the second adhesive area 2. The adhesive of the first adhesive area 1 is a first colloid, and the adhesive of the second adhesive area 2 is a second colloid. The second colloid has a better skin-friendly performance to the wound than the first colloid, so that the stoma base plate near the stoma of the patient is more comfortable, can better fit the side around the stoma, and has a better fit with the skin, ensuring that the side around the stoma is not easy to leak, so that it is not easy to dirty the patient's clothes, and ensure that the patient has better comfort in use.

[0031] Among them, the first colloid is medical hydrocolloid or medical acrylic glue, and the second colloid is medical silicone gel. Since medical silicone gel has good waterproof, anti-corrosion, moisture-proof and chemical medium resistance, it will not be contaminated and deteriorated by urine or feces during long-term use, and medical silicone gel has good softness, low viscosity, extremely low sensitization rate, and colloid does not transfer, so it provides good sealing performance when it is attached to the patient's stoma side. At the same time, it is more comfortable, easy to tear off after use, and has a certain repair effect on the skin, so it is more conducive to the patient's recovery and makes the user experience better; the first adhesive area 1 is set to medical hydrocolloid or medical acrylic glue, and the shape of the second adhesive area 2 can be fixed by the first adhesive area 1, so that the stoma base plate 100 is more convenient to use, and the medical hydrocolloid or medical acrylic glue has a large viscosity, which can provide sufficient adhesion to ensure that the stoma base plate can carry and suspend the stoma bag and its contents. Therefore, this structural design ensures that the stoma base plate 100 is securely sealed and fits the stoma, while better protecting the patient's skin and improving the user experience.

[0032] Of course, the materials of the first adhesive area 1 and the second adhesive area 2 include but are not limited to the above. However, while ensuring better skin-friendliness, the hardness of the first adhesive area 1 should be greater than the hardness of the second adhesive area 2, so that the stoma base plate 100 can have a fixed shape when in use, making it easier to be installed around the patient's stoma.

[0033] The first adhesive area 1 and the second adhesive area 2 may be in a matching square, triangle or special shape. Alternatively, the second adhesive area 2 may also be in a petal shape or an ellipse shape, etc., to ensure that the first adhesive area 1 and the second adhesive area 2 can be completely arranged around the patient's stoma.

[0034] Preferably, if Figure 1 and Figure 2As shown in , the second adhesive area 2 is set in a disc shape, the first adhesive area 1 is in a ring shape, and the second adhesive area 2 is set concentrically with the first adhesive area 1, so that the first adhesive area 1 and the second adhesive area 2 are evenly distributed around the stoma, and the covering effect of various parts of the stoma is more consistent, and leakage is better avoided. The size of the second adhesive area 2 is not specifically limited to ensure that the second adhesive area 2 can be completely covered on the outer periphery of the patient's stoma.

[0035] In order to facilitate the connection between the ostomy bag body 200 and the stoma of the patient, a through hole 21 can be formed on the second adhesive area 2, so that the urination or defecation tube led out of the patient's body can be connected to the ostomy bag body 200.

[0036] Moreover, a cutting mark is provided in the adhesive area, and the cutting mark is configured to facilitate manual cutting of a stoma hole suitable for stoma penetration, so as to facilitate the use of the patient. The cutting mark can be provided only in the first adhesive area 1, or the cutting mark can extend from the second adhesive area 2 to the first adhesive area 1.

[0037] There are many styles of cutting marks. For example, the cutting mark can be in the shape of a "cross" to facilitate medical staff to insert scissors for cutting; or, the cutting mark can be a plurality of concentrically distributed circular coils with different diameters, and medical staff can cut along different concentric circles according to the size of the stoma. Alternatively, the cutting mark is a slit-shaped notch located in the center of the second adhesive area 2, and medical staff can directly tear along the notch to form a through hole 21 manually, without the need for tools, and the operation is more convenient.

[0038] The size of the first adhesive area 1 can match the size of the second adhesive area 2, wherein, when the first adhesive area 1 and the second adhesive area 2 are both disc-shaped, the outer diameter of the first adhesive area 1 is greater than the outer diameter of the second adhesive area 2, so that at least a portion of the first adhesive area 1 can be adhered to the patient's skin to ensure better leakage-proof performance of the stoma base plate 100.

[0039] In one embodiment, the first adhesive region 1 is provided in a circular ring shape, and the first adhesive region 1 is sleeved on the outer peripheral side of the second adhesive region 2, so as to save more materials.

[0040] In another embodiment, the first adhesive area 1 is provided in a disc shape, and the second adhesive area 2 is attached to one side of the first adhesive area 1 to ensure that the second adhesive area 2 is more flat and wrinkles are avoided.

[0041] The first adhesive region 1 and the second adhesive region 2 are respectively arranged on different substrates, and the first adhesive region and the second adhesive region are connected together by splicing the substrates. For example, during manufacturing, the first adhesive region 1 can be formed by the first substrate, and the second adhesive region 2 can be formed by the second substrate, and then the manufactured first adhesive region 1 and the manufactured second adhesive region 2 can be fixed together by welding or gluing to form the stoma base plate 100.

[0042] In other embodiments, the first adhesive area and the second adhesive area are disposed on the same substrate. For example, after the first adhesive area 1 is formed by the first substrate, a layer of the second adhesive area 2 can be directly brushed or compounded on one side of the first adhesive area 1 to avoid separation between the first adhesive area 1 and the second adhesive area 2, which would affect the use effect.

[0043] The utility model also provides an ostomy bag assembly 1000, such as Figure 3 As shown in , the ostomy bag assembly 1000 includes an ostomy bag body 200 and the above-mentioned ostomy base plate 100. A through hole 21 can be formed on the second adhesive area 2 of the ostomy base plate 100, and the ostomy bag body 200 is connected with the through hole 21 to communicate with the ostomy bag. The ostomy bag can collect the patient's urine or feces, and the ostomy base plate 100 is in direct contact with the skin around the stoma of the patient, which can better prevent the patient's skin from feeling uncomfortable, and has a good anti-leakage effect and is not easy to fall off, which reduces the discomfort caused by the ostomy bag assembly 1000 to the patient and is more conducive to the patient's recovery.

[0044] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
