Description

Technical Field

[0001] This utility model relates to the field of ostomy bag technology, and in particular to an ostomy bag with an integrated filtration system. Background Technology

[0002] An ostomy is a surgical procedure for patients with digestive or urinary system diseases. It works by surgically bringing one end of the intestine or urethra to the body surface, creating an opening to allow waste to drain. Clinically, ostomies are commonly used to treat rectal and bladder diseases (such as rectal cancer, bladder cancer, and intestinal obstruction), aiming to protect distal bowel segments, reduce obstruction, and promote healing. Post-operatively, patients require special care, including adjusting their diet, regularly monitoring the color, shape, and size of the stoma, keeping the stoma and surrounding skin clean, and selecting an appropriate ostomy bag for proper fitting to prevent leakage and infection.

[0003] Excrement contains various components, including water, electrolytes, organic matter, and bacteria. Among these, some components, such as hydrogen sulfide and ammonia, are the main causes of odor. If these gases cannot be expelled in time, they can cause the bag to swell or even rupture.

[0004] Therefore, the ability of an ostomy bag to effectively deodorize and expel odorless gases directly affects the user's comfort and privacy during use. Most existing ostomy bag filters use only carbon sheets, which are not waterproof or their adsorption effect deteriorates after contact with water. During prolonged use, ostomy bags may still swell and develop odors, requiring frequent changes. This application addresses these shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide an ostomy bag with an integrated filtration system that can effectively adsorb and purify the odor of excrement and discharge odorless gas. It is suitable for long-term wear and solves the problem that existing ostomy bags lose their deodorizing and venting functions when the carbon sheet is soaked with liquid.

[0006] To solve the above problems, this utility model provides an ostomy bag with an integrated filtration system, including a bag body and an integrated filtration system. The integrated filtration system is set in the chamber of the bag body for receiving excrement, and the bag body is provided with an exhaust port for gas to be discharged.

[0007] The integrated filtration system includes a water-resistant and breathable membrane, an inner membrane, a filter module, an outer membrane, and a water-resistant and breathable membrane arranged sequentially. The filter module includes a filter carbon sheet and a support frame located on its outer side. The support frame supports the inner and outer membranes, forming a space for containing and allowing gas to pass through. Both the inner and outer membranes are made of airtight and waterproof material. Both the inner and outer membranes are provided with air inlets for allowing gaseous waste to enter. The outer membrane is provided with an exhaust port two connected to exhaust port one for allowing purified gas to be discharged.

[0008] The support frame is narrower than the filter carbon sheet, and the support frame is located in the middle of the filter carbon sheet.

[0009] The water-resistant and air-permeable membrane blocks solid and liquid discharge while allowing gas to pass through. The inner and outer membrane layers are used for welding connections and blocking discharge. The built-in support frame prevents the filter carbon sheets from being squeezed, which could compress the filter channels.

[0010] The dual-channel air intake structure formed by the two air inlets allows gaseous waste to pass through the water-resistant and breathable membranes on both sides and enter the interior of the carbon filter for adsorption and purification. This ensures that the gaseous waste is odorless and does not breed bacteria after passing through the carbon filter. Compared to a single filter, the gas in the ostomy bag can more easily enter and exit through the dual inlets, providing a more comfortable user experience for ostomy patients.

[0011] According to one embodiment of the present invention, the air inlet and exhaust outlet in the integrated filtration system are arranged in a bottom-up and top-down configuration to ensure the filtration effect of the gas.

[0012] According to one embodiment of the present invention, the integrated filtration system is located in the upper middle part of the bag body, and one end of it with an air inlet is suspended. After the excrement enters, the solid and liquid descend and the gas rises. The suspended air inlet facilitates the entry of gas.

[0013] According to one embodiment of the present invention, the bag body includes a base, a body-side bag membrane, and a non-body-side bag membrane. The exhaust port is disposed on the non-body-side bag membrane, and the integrated filtration system is disposed between the body-side bag membrane and the non-body-side bag membrane.

[0014] According to one embodiment of the present invention, the body-side bag membrane and / or non-body-side bag membrane are made of transparent or skin-colored material.

[0015] According to one embodiment of the present invention, the bag body further includes body-side nonwoven fabric and non-body-side nonwoven fabric, respectively disposed on the outer side of the body-side bag body film and the outer side of the non-body-side bag body film. The nonwoven fabric is used to improve comfort.

[0016] According to one embodiment of the present invention, the inner film and / or outer film are made of weldable polyethylene or polyester film.

[0017] According to one embodiment of the present invention, the water-blocking and air-permeable membrane is a water-blocking and air-permeable polyacrylic acid or polytetrafluoroethylene membrane.

[0018] According to one embodiment of the present invention, the support frame is made of plastic, preferably polyethylene plastic.

[0019] According to one embodiment of the present invention, the filter carbon sheet is made of activated carbon, chitosan, or nano-silver materials, which have adsorption, degradation and antibacterial properties.

[0020] The beneficial effects of this invention are that by setting up an integrated filtration system, which adopts a combination of inner and outer double-layer membranes and double water-resistant and breathable membranes, the water-resistant and breathable membranes are used to prevent solid and liquid excrement from contaminating the filter carbon and to prevent gaseous excrement from passing through. The inner and outer membranes are used to weld and block excrement, thereby preventing the adsorption effect of the filter carbon from deteriorating after contact with water. The built-in support frame is used to prevent the filter carbon from being squeezed and the filtration channel from being compressed. The dual-channel air intake structure combined with the suspension design makes it easier for gas in the ostomy bag to enter and exit through both ports compared to a single filter. After the gaseous excrement passes through the inner and outer double water-resistant and breathable membranes, it enters the interior of the filter carbon for adsorption and purification, so that the gaseous excrement is deodorized after passing through the filter carbon, bringing a more comfortable user experience to ostomy patients.

[0027]

Example 1

[0028] An ostomy bag with an integrated filtration system, such as Figure 1 , including the bag body and integrated filtration system 3.

[0029] The bag body includes a base plate 6, a body-side bag membrane 4, and a non-body-side bag membrane 2. The outer side of the bag body is provided with a body-side non-woven fabric 5 and a non-body-side non-woven fabric 1. The body-side bag membrane 4 and the non-body-side bag membrane 2 are welded together to form the bag body. The integrated filtration system 3 is located between the non-body-side bag membrane 2 and the body-side bag membrane 4, and preferably its upper end is connected to the non-body-side bag membrane 2. The non-body-side bag membrane 2 is provided with an exhaust port 12, which is located at the top center position. In this embodiment, the body-side bag membrane 4 and the non-body-side bag membrane 2 are preferably made of transparent or skin-colored material.

[0030] In other embodiments, the vent 12 is not limited to being located on the non-body side bag membrane 2.

[0031] The non-woven fabric 5 on the body side is directly attached to the skin to improve comfort and reduce bag noise. The non-woven fabric 1 on the non-body side consists of two small pieces for observing the stoma.

[0032] like Figure 2 The integrated filtration system 3 includes a water-resistant and breathable membrane 7, an inner membrane 8, a filtration module, an outer membrane 11, and the water-resistant and breathable membrane 7 arranged in sequence. The filtration module includes a filter carbon sheet 10 and a support frame 9 located on its outer side. The filter carbon sheet 10 preferably adopts a rectangular structure. The width of the support frame 9 is smaller than the width of the filter carbon sheet 10, and the support frame 9 is located in the middle of the filter carbon sheet 10.

[0033] The support frame 9 supports the inner membrane 8 and the outer membrane 11, forming a space for containing gas and allowing gas to pass through. Both the inner membrane 8 and the outer membrane 11 are made of airtight and waterproof material. Both the inner membrane 8 and the outer membrane 11 are provided with air inlets for gas excrement to enter. The outer membrane 11 is provided with an exhaust port 13 that is connected to the exhaust port 12 for gas to be discharged.

[0034] Exhaust port one and exhaust port two are preferably designed as cuts.

[0035] It should be noted that both water-resistant and breathable membranes 7 are made of water-resistant and breathable materials, and are welded and fixed to the inner membrane 8 and the outer membrane 11 respectively. Both the inner membrane 8 and the outer membrane 11 are made of non-breathable waterproof materials. The water-resistant and breathable membrane 7 is used to block solids and liquids in excrement while allowing gas to pass through. The inner membrane 8 and the outer membrane 11 are used to wrap the filter carbon sheet 10. The inner membrane 8 has one air inlet, and the outer membrane 11 has one air inlet and one exhaust outlet. The air inlet position corresponds to the water-resistant and breathable membrane 7. The filter carbon sheet 10 has adsorption and antibacterial properties. The support frame is made of plastic and is used to support the filter carbon sheet, preventing the carbon sheet from being squeezed and causing the filter channel to be compressed. Furthermore, the top of the outer membrane 11 is welded to the non-body side bag membrane 2 to fix the integrated filtration system, and the position of the second exhaust outlet 13 of the outer membrane corresponds to the position of the first exhaust outlet 12 of the non-body side bag membrane 2. Figure 1 The integrated filtration system 3 is located in the upper middle part of the bag body. The end with the air inlet is suspended. After the excrement enters, the solid and liquid sinks and the gas rises. The suspended air inlet facilitates the entry of gas.

[0036] The dual-channel air intake structure formed by the two air inlets allows gaseous waste to pass through the water-resistant and breathable membranes 7 on both sides and then enter the interior of the carbon filter for adsorption and purification. This ensures that the gaseous waste is odorless and does not breed bacteria after passing through the carbon filter. Compared to a single filter, the gas in the ostomy bag can more easily enter and exit through the dual inlets, providing a more comfortable user experience for ostomy patients.

[0037] like Figure 2 The air inlet and exhaust outlet in the integrated filtration system 3 are arranged in a two-down-one-up configuration to ensure the filtration effect of the gas.

[0038] The integrated filtration system effectively improves the problems of bag bloating and odor during ostomy bag use. The principle is as follows: the user's excrement exits from the stoma and enters the ostomy bag through the base plate 6. Solids and liquids enter the bottom of the bag under gravity. The filtration system, through the inner and outer membranes and the water-resistant and breathable membrane 7, prevents liquid leakage into the filtration system while allowing gas to quickly enter the filtration chamber. The support frame 9 and filter carbon plates 10 allow gas to be adsorbed and purified within the filter carbon plates and concentrated at the top of the filter. Simultaneously, odorless gas is discharged through the outer welded membrane 11 and the breathable slits on the non-body side of the bag membrane 2. The dual-end air intake design and the centrally located top of the ostomy bag improve exhaust efficiency, ensure continuous use, and enhance the user experience for ostomy patients.

[0039] Preferably, the inner film 8 and / or the outer film 11 are made of weldable polyethylene or polyester film.

[0040] Preferably, the water-blocking and breathable membrane 7 is made of water-blocking and breathable polyacrylic acid or polytetrafluoroethylene membrane.

[0041] Preferably, the support frame 9 is made of plastic, preferably polyethylene plastic.

[0042] Preferably, the filter carbon sheet 10 is made of activated carbon, chitosan, or nano-silver materials, which have adsorption, degradation and antibacterial properties.

[0043] The shapes of the components in the integrated filtration system are not limited to those shown in the figure. The composition order, shape, and material design of each component from the inside out are all within the protection scope of this invention.

[0044] This utility model has a simple design structure, simple process, low equipment requirements, and all processes can be completed by hot welding.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments.
