Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to an ostomy device. Background Technology

[0002] like Figure 1 As shown, existing stoma waste collection systems mainly consist of a stoma tray 1' and a stoma waste collection device 2'. Based on the connection method between the stoma tray 1' and the stoma waste collection device 2', they are divided into one-piece and two-piece systems. The size of the central hole in the stoma tray 1' is adjusted according to the size of the stoma. To reduce the risk of leakage, an anti-leakage paste 5' is usually applied around the stoma 3' to increase the seal between the stoma 3' and the stoma tray 1', thereby preventing waste leakage to the skin around the stoma 3'. However, in reality, stoma care workers in China have found that, due to improper operation by users or skin folds at the stoma 3', gaps exist between the anti-leakage paste 5' and the skin around the stoma 3'. Furthermore, because waste is corrosive, there are still many cases of inflammation and ulceration of the skin around the stoma 3' caused by waste leakage.

[0003] On the other hand, when constructing stoma 3', the lack of support around the intestine may lead to unsatisfactory height; after a period of time, the permanent stoma 3' retracts into the abdomen, making it difficult to ensure that the skin around the constructed stoma 3' is sealed with the stoma disc 1'. Although the use of a convex stoma disc 1' provides some relief, it does not completely solve the problems of stoma 3' retraction and excrement leakage.

[0004] Third, the stoma tray 1' adheres to the abdominal skin surface through the tray containing the adhesive layer 4'. Long-term adhesion can cause tension damage around the tray due to the adhesive layer 4', which can lead to problems such as skin allergies.

[0005] In view of the above problems, the present invention provides an ostomy device, and this case arises from this invention. Summary of the Invention

[0006] This invention provides a stoma device that features strong sealing, prevents gaps between the device and the stoma, prevents stoma retraction, and is easy to install. Specifically, this invention is achieved through the following technical solution:

[0007] An ostomy device includes a support body and a sealing device; the support body is annular and is used to support the everted intestine at the stoma; the sealing device includes an elastic sealing body and a disc body, the disc body has a through hole, and the sealing body is arranged in an annular shape around the through hole; the elastic sealing body is pressed tightly against the support body to form a tight seal between the support body and the elastic sealing body, and the disc body is disposed around the stoma and connected to the elastic sealing body.

[0008] Furthermore, the outer ring surface of the support has several protrusions.

[0009] Furthermore, the protrusions are mushroom-shaped.

[0010] Furthermore, the support is made of an elastic material.

[0011] Furthermore, the axial section profile of the support is arched, circular, or elliptical; the opening of the arched profile faces the center of the support.

[0012] Furthermore, the ring-shaped support is hollow inside, forming a cavity filled with liquid or gas.

[0013] Furthermore, the thickness of the disc body is between 0.2 mm and 2 mm, and the thickness of the sealing body is between 20 μm and 200 μm.

[0014] Furthermore, the material of the elastic seal is selected as silicone or thermoplastic elastomer (TPE).

[0015] Furthermore, the material of the support is selected as silicone or thermoplastic elastomer (TPE).

[0016] Furthermore, the stoma device also includes an excrement collection device, which is integrated with or separate from the sealing device.

[0017] Furthermore, the excrement collection device and the sealing device are connected separately, with the excrement collection device connected to the sealing device via a connecting buckle.

[0018] Furthermore, the stoma device also includes a waist belt; the excrement collection device and the sealing device are connected as one piece, and the waist belt is connected to the disc in the sealing device; the excrement collection device and the sealing device are connected separately, with the excrement collection device connected to the sealing device via a connecting buckle, and the waist belt connected to the connecting buckle or the disc in the sealing device.

[0019] Furthermore, the excrement collection device and the sealing device are connected as a single unit, with the disc in the sealing device having connecting slots or hooks; alternatively, the excrement collection device and the sealing device are connected separately, with the excrement collection device connected to the sealing device via a connecting buckle, and the connecting buckle or the disc in the sealing device having connecting slots or hooks.

[0020] The beneficial effects of this application are as follows:

[0021] Firstly, since the support ring has a fixed size, only a sealing device matching the size of the sealing body needs to be selected, eliminating the need for manual cutting. The sealing ring is elastic and, by fitting over the support ring, achieves a tight fit against the intestinal wall, eliminating the need for sealing paste. Furthermore, the disc does not require adhesive to fix it to the skin. The sealing device provides a seamless seal at the stoma, preventing skin damage caused by leakage of excrement.

[0022] The outer ring surface of the support has several protrusions to prevent pressure damage from prolonged contact with the intestine. Furthermore, the support provides support to the intestine at the stoma site, preventing intestinal retraction. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 2 , Figure 3 As shown, a stoma device includes a support body 1, a sealing device 2, and an excrement collection device 3. The support body 1 is fitted onto the stoma and fixedly connected to the outer wall of the intestine 4. The sealing device 2 is assembled outside the support body 1. The excrement collection device 3 is connected to the sealing device 2 and the interior of the excrement collection device 3 is connected to the intestine 4. The support body 1 and the sealing device 2 achieve a sealed connection between the intestine 4 and the excrement collection device 3.

[0031] The method of fixing the support 1 to the outer wall of the intestine 4 is as follows:

[0032] like Figure 2 As shown, the end of the intestine 4 extending out of the human body passes through the support body 1. The end of the intestine 4 is everted, and the wall of the intestine 4 wraps around the support body 2. At the same time, the everted wall of the intestine 4 is connected to the human skin 5 to form a stoma. The support body 1 also serves to support the end of the intestine 4 and prevent the intestine 4 at the stoma from retracting.

[0033] The sealing device 2 is assembled at the stoma and engages with the support body 1. At the axial section of the stoma of the intestine 4, from the outside to the inside, the components are the sealing device 2, the wall of the intestine 4, the support body 1, and the wall of the intestine 4.

[0034] I. Support 1.

[0035] The support 1 is ring-shaped, with its outer ring slightly larger than the inner ring of the sealing device 2; the axial cross-sectional profile of the support 1 is arched, circular, or elliptical; the opening of the arched profile faces the center of the support 1, and the arched profile can maximize the diameter of the inner ring without compressing the intestinal space 4 inward while keeping the outer ring diameter of the support 1 unchanged; the shape of the support 1 can reduce the pressure exerted by the support 1 on the intestinal wall 4.

[0036] The outer ring surface of the support 1 is provided with several protrusions; when the sealing device 2 is installed at the intestinal 4 stoma, the intestinal 4 wall is clamped between the support 1 and the sealing device 2. The design of the protrusions can reduce the contact area between the support 1 and the intestinal 4 wall, so that the blood vessels in the intestinal 4 wall at this location are not squeezed, and the blood can still run normally, making it less likely to cause intestinal 4 necrosis; the protrusions are mushroom-shaped, which can increase their elasticity, and when the protrusions come into contact with the intestinal 4 wall, the intestinal 4 wall will not be damaged by pressure.

[0037] like Figure 4 , Figure 5 As shown, the ring body of the support 1 is hollow inside, that is, the axial section of the support 1 is annular. The hollow support 1 can reduce the weight of the support 1, while also making the support 1 elastic. The hollow part provides space for the ring wall to be squeezed inward.

[0038] Liquid or gas can be filled into the hollow part inside the support body 1 to improve its support performance.

[0039] The support 1 is made of a material with a certain degree of elasticity, such as silicone or thermoplastic elastomer (TPE). The thermoplastic elastomer (TPE) can be TPES, TPV, TPO, TPU, TPEE, or TPAE, etc.

[0040] II. Sealing device 2.

[0041] like Figure 3 As shown, the sealing device 2 includes a disc body 21 with a through hole at the center. On one side of the disc body 21, an annular sealing body 22 is provided around the through hole.

[0042] The annular seal 22 is made of a material with a certain degree of elasticity, such as silicone or thermoplastic elastomer (TPE). The thermoplastic elastomer (TPE) can be TPES, TPV, TPO, TPU, TPEE, or TPAE, etc.

[0043] The thickness of the disc body 21 is between 0.2 mm and 2 mm, and the thickness of the sealing body 22 is between 20 μm and 200 μm.

[0044] When in use, the sealing device 2 is fastened to the stoma of the intestine 4. The annular sealing body 22 is fitted over the support body 1. Because the sealing body 22 is elastic, it adheres tightly to the intestinal wall of the outside of the support body to form a seal. The other side of the disc body 21 without the sealing body 22 is in close contact with the human skin to form a seal.

[0045] 3. Excrement collection device 4.

[0046] The excrement collection device 3 is connected to the side of the disc 21 of the sealing device 2 that is not in contact with human skin. The sealing device 2 and the excrement collection device 3 can be connected separately or as a single unit. The connection port of the excrement collection device 3 is connected to the through hole in the sealing device 2.

[0047] like Figure 3 As shown, when the sealing device 2 and the excrement collection device 3 are connected separately, the following method can be adopted: a connecting buckle 6 is installed on the disc body 21 of the sealing device 2, and the connection port of the excrement collection device 3 is connected to the connecting buckle 6 to realize the connection between the sealing device 2 and the excrement collection device 3. When replacing, only the excrement collection device 3 needs to be replaced.

[0048] IV. Belt.

[0049] The stoma device also includes a waist belt, which further strengthens the connection between the stoma device and the human body.

[0050] When the sealing device 2 and the excrement collection device 4 are integrated, the belt is connected to the disc 21 in the sealing device 2. When in use, the belt is tied around the body to further fix one side of the disc 21 to the body.

[0051] When the sealing device 2 and the excrement collection device 4 are separate structures, the belt is connected to the connecting buckle 6 or the disc 21.

[0052] A specific embodiment of the connection between the belt and the disc body 21 is as follows:

[0053] The disc body 21 is provided with a slot or hook for connecting to the belt, and a fixing protrusion or hole is provided at the corresponding belt position, which cooperates with the slot or hook on the disc body 21 to connect the belt to the disc body 21.

[0054] A specific embodiment of the connection between the belt and the connecting buckle 6 is as follows:

[0055] The connecting buckle 6 has a slot or pin for connecting with the belt, and the corresponding belt has a fixing protrusion or hole that cooperates with the slot or pin on the connecting buckle 6 to connect the belt and the connecting buckle 6.

[0056] The above are preferred embodiments of the present invention. Any other simple substitutions and modifications made under the premise of the present invention should be considered as falling within the protection scope of the present invention.
