Description

Technical Field

[0001] This invention relates to the field of medical tool technology, and more specifically to an ostomy bag. Background Technology

[0002] An enterostomy is a surgical procedure used to treat intestinal diseases. An opening is created in the abdominal wall, through which the intestines are pulled out and exposed to the outside of the body, forming a drainage opening to aid in excretion. A colostomy bag is typically used to collect the excreted feces. This procedure is commonly used to treat intestinal obstruction, intestinal perforation, and other intestinal conditions. After the surgery, the patient can expel feces through this drainage opening.

[0003] Due to the adhesive issue, leakage may occur during use. Since the ostomy bag is usually hidden inside clothing, the user cannot be aware of the leakage immediately. The leakage may contaminate the user's clothing and cause adverse effects if it is exposed to the viewer.

[0004] Currently, the solution to leakage problems is usually to improve the sealing performance, such as the "iris-shaped aperture seal for ostomy bag" disclosed in patent number CN102883691B; or the "negative pressure vacuum drainage ostomy bag" disclosed in patent number CN109820636B, which avoids leakage by using negative pressure.

[0005] The existing technologies described above all prevent leakage before it occurs. This solution designs an ostomy bag that can remind the user to change it promptly after leakage occurs. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an ostomy bag to solve the aforementioned problems.

[0007] This invention provides the following technical solution:

[0008] An ostomy bag includes a flexible base layer and a retaining ring disposed on one side of the flexible base layer. An adhesive layer is disposed on the other side of the flexible base layer in a region that avoids the annular groove. A heat-conducting zone and a liquid inlet zone are uniformly disposed within the annular groove. A storage cavity is formed within the retaining ring. The opening end of the storage cavity is connected to the liquid inlet zone and is provided with a polyvinyl alcohol film with a degree of alcoholysis of 88%-94%. The storage cavity is filled with calcium oxide particles. A heat-conducting element is disposed on the storage cavity extending to a corresponding heat-conducting zone.

[0009] Preferably, the flexible base layer includes an inner ring base layer and an outer ring base layer arranged from the inside out, both of which are fixed to the sidewall of the retaining ring, and the annular groove is formed between the inner ring base layer and the outer ring base layer.

[0010] Preferably, a through hole is provided in the middle of the inner ring base layer.

[0011] Preferably, the heat-conducting zone and the liquid-inlet zone in the annular groove are alternately and evenly distributed circumferentially.

[0012] Preferably, a blocking component is provided inside the storage cavity between the polyvinyl alcohol film and the calcium oxide particles. The blocking component is used to discharge the heat generated by the calcium oxide particles absorbing water from the opening end of the storage cavity.

[0013] Preferably, the blocking assembly includes a housing and a rotating component rotatably connected to the inner cavity of the housing, wherein the rotating component is adapted to the inner cavity of the housing, the liquid inlet of the housing is connected to the opening end of the storage cavity, and the liquid outlet of the housing is connected to the calcium oxide particles.

[0014] Preferably, a water-absorbing sponge is provided on one side of the rotating component. When the water-absorbing sponge faces the liquid inlet, it is in a fluffy state. When the water-absorbing sponge faces the liquid outlet, it cooperates with the inner wall of the housing to compress it.

[0015] Preferably, a plurality of melting water lines are provided between the rotating component and the inner wall of the housing, so that the water-absorbing sponge on the rotating component is normally oriented towards the liquid inlet.

[0016] Preferably, it also includes a return spring, the elastic force of which pushes the absorbent sponge on the rotating part toward the liquid outlet.

[0017] Preferably, the liquid outlet of the shell is provided with an isolation mesh to prevent calcium oxide particles from entering the interior of the shell.

[0018] The present invention has the following beneficial technical effects:

[0019] When leakage occurs during the use of the ostomy bag, the leaked fluid enters the storage cavity and reacts with calcium oxide particles to generate heat. The heat is conducted through a heat-conducting component to a corresponding heat-conducting area, which then directly contacts the user's skin to generate heat and alert the user to the leakage.

[0020] This invention uses a polyvinyl alcohol film with a degree of alcoholysis of 88%-94% to block sweat. The polyvinyl alcohol film with a degree of alcoholysis of 88% or higher can only be dissolved when sewage leaks. This design can prevent sweat from accidentally triggering the system.

[0021] The blocking component prevents the heat generated by the reaction between the leaking liquid and the calcium oxide particles from being directly conducted to the skin and causing burns. Furthermore, the blocking component allows a certain amount of fecal water to be collected before reacting with the calcium oxide particles, increasing the duration and effectiveness of the heating process and thus improving the user's alerting effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] A type of sac, such as Figure 1-5 As shown, it includes:

[0032] The flexible base layer 1 includes an inner base layer 101 and an outer base layer 102. Both the inner base layer 101 and the outer base layer 102 are fixed on the same side of the retaining ring 2. A gap is left between the outer contour of the inner base layer 101 and the inner contour of the outer base layer 102 to form an annular groove 11. A through hole 12 is opened in the middle of the inner base layer 101. The through hole 12 is located inside the retaining ring 2 and is coaxially arranged. Sewage is transported outward through the through hole 12. An adhesive layer is provided on the side of the inner base layer 101 and the outer base layer 102 away from the retaining ring 2. The adhesive layer is used to stick to the user's abdomen. The retaining ring 2 is used to detachably install external sewage collection bags and other components.

[0033] The retaining ring 2, located in the annular groove 11, has multiple sets of heat-conducting zones 3 and liquid inlet zones 4 evenly arranged around the circumference of the annular groove 11, with the heat-conducting zones 3 and liquid inlet zones 4 alternating one another; for example Figures 3-4As shown, the retaining ring 2 has multiple sets of storage cavities 5 inside, and the storage cavities 5 are used in a one-to-one correspondence with the liquid inlet area 4. The opening end of the storage cavity 5 is connected to the corresponding liquid inlet area 4. The opening end of the storage cavity 5 is provided with a polyvinyl alcohol film 6 with a thickness ≤50μm. The degree of alcoholysis of the polyvinyl alcohol film 6 is greater than 88%. The degree of alcoholysis of the polyvinyl alcohol film 6 can be selected as 88%, 90%, 92%, 94%, etc., so that the polyvinyl alcohol film 6 with this degree of alcoholysis will not be dissolved for more than 24 hours when in contact with sweat, while the polyvinyl alcohol film 6 with this degree of alcoholysis will be dissolved within 3min-8min when in contact with fecal water.

[0034] Because the flexible base layer 1 has a certain thickness, the polyvinyl alcohol film 6 does not come into direct contact with the skin, thus preventing the transfer of a small amount of sweat from the skin to the polyvinyl alcohol film 6.

[0035] The storage cavity 5 is filled with calcium oxide particles, and a blocking component 7 is installed inside the storage cavity 5. The blocking component 7 is located between the polyvinyl alcohol film 6 and the calcium oxide particles, which can prevent the calcium oxide particles from impacting the polyvinyl alcohol film 6 and causing damage.

[0036] like Figure 5 As shown, the blocking component 7 includes a housing 71, a rotating component 74, an absorbent sponge 75, a return spring 76, and melting lines 77. The housing 71 is fixed inside the storage cavity 5. The housing 71 is hollow in the middle and has an inlet 72 on one side near the opening of the storage cavity 5. The housing 71 has an outlet 73 on one side near the calcium oxide particles 8. The rotating component 74 is rotatably connected inside the housing 71 and is closer to the outlet 73 than the inlet 72. The return spring 76 can be a torsion spring sleeved on the end of the rotating component 74. The shape of the rotating component 74 is adapted to the inner cavity of the housing 71. The inlet 72 and outlet 73 of the housing 71 can be blocked by the rotating component 74. An absorbent sponge 75 is fixedly provided on one side of the rotating component 74. Multiple melting lines 77 are provided between the inner wall of the housing 71 and the rotating component 74. One end of the melting line 77 extends into the interior of the absorbent sponge 75.

[0037] The axis of rotation of the rotating component 74 is closer to the outlet 73 than the inlet 72, so that under normal conditions... Figure 5 The absorbent sponge 75 shown is in a natural, uncompressed state.

[0038] Under normal conditions, the rotating component 74 is kept in a state of tension by multiple taut water lines 77. Figure 5 As shown in the diagram, the return spring 76 has elastic force.

[0039] A heat-conducting element (not shown in the attached figure) is provided between the inner wall of the storage cavity 5 containing calcium oxide particles 8 and the heat-conducting area 3. The end of the heat-conducting element can act as the heat-conducting area 3 for contact with the user's skin. The heat-conducting area 3 is slightly raised relative to the annular groove 11. The slight bulge of the heat-conducting area 3 helps to suspend the liquid inlet area 4.

[0040] Working principle:

[0041] The flexible base layer 1 is attached to the user's abdomen with an adhesive layer, the fecal bag is snapped onto the snap ring 2, and fecal matter is discharged outward into the fecal bag through the through hole 12.

[0042] When leakage occurs due to insufficient adhesion, the fecal water is transported to the annular groove 11 through the gap between the inner base layer 101 and the skin. The fecal water comes into contact with the polyvinyl alcohol film 6 corresponding to the liquid inlet area 4 on the annular groove 11, thereby dissolving the polyvinyl alcohol film 6. Subsequent fecal water or sweat can pass through the opening end of the storage cavity 5, which originally had the polyvinyl alcohol film 6, and enter the inner cavity of the storage cavity 5 without obstruction.

[0043] The fecal matter or sweat entering the inner cavity of storage chamber 5 first enters the interior of housing 71 through inlet 72 and is absorbed by absorbent sponge 75. As the absorbent sponge 75 absorbs more water (or after a period of time), even the portion of the sponge 75 furthest from inlet 72 becomes damp. This portion of the sponge 75 transfers the moisture to melting line 77. Melting line 77 dissolves and breaks upon contact with water. Under the elastic force of return spring 76, rotating component 74 rotates 180° relative to housing 71, causing the absorbent sponge 75 on rotating component 74 to rotate closer to outlet 73. This process... The absorbent sponge 75, originally located at the upper part of the housing 71, rotates to the lower part. Now positioned at the lower part of the housing 71, the sponge 75 is compressed due to the confinement of the space within the housing 71, causing the water adhering to its interior to be squeezed out. This squeezed-out water reacts with the calcium oxide particles 8 through the outlet 73, generating heat. This heat is blocked by the rotating component 74, preventing direct contact with the user's skin. The heat is then conducted through a heat-conducting component to the heat-conducting area 3, where it comes into contact with the user's skin. This allows the user to feel the heat in the heat-conducting area 3 while preventing burns. The temperature of the heat-conducting area 3 at its end can be controlled according to the material and length of the heat-conducting component.

[0044] By concentrating sweat or fecal matter into the absorbent sponge 75, the water content is increased; this prevents small amounts of sweat or fecal matter from intermittently contacting the calcium oxide particles 8, so that the small amount of heat generated cannot be perceived by the user; even if sweat dissolves the polyvinyl alcohol film 6, the small amount of sweat can still be absorbed by the absorbent sponge 75.

[0045] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
