Technical Field

[0001] The utility model relates to the technical field of ostomy bags, and more particularly to a washable ostomy bag. Background Art

[0002] During gastrointestinal surgery, an artificial stoma is sometimes required. After surgery, the patient uses an ostomy bag to collect digestive waste. Due to temporary changes in intestinal physiology, flora, and diet, patients may experience digestive dysfunction symptoms such as constipation, watery stools, and flatulence. This requires timely deflation, flushing, or replacement of the ostomy bag.

[0003] In addition to using a drainage portion for drainage, for example, excreta (gas, liquid, solid) must be discharged from the drainage portion. To facilitate flushing of the fistula bag, a cleaning port is usually provided on the fistula bag. A syringe is used to push a cleaning liquid (saline) into the cleaning port to clean the fistula bag. However, the clean water port is often located at the top. The flushing saline brings sewage and contaminates the stoma, which can easily lead to stoma infection.

When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on this technical solution. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0037] Existing ostomy bags, in addition to easily causing stains on the stoma during cleaning, also have an outlet at the bottom for excrement discharge. However, these outlets are typically large and sealed by rolling them up, making discharge inconvenient. Using a smaller connector to connect to an external standard urine bag via a hose can easily lead to clogging of the smaller connector by feces and other residues. Therefore, this solution employs the following embodiments to address the aforementioned issues. The details are as follows:

[0038] See also Figure 1 、 Figure 2The present embodiment provides a washable ostomy bag for connecting to a stoma on a human body to facilitate the collection of human excrement discharged from the stoma. To facilitate the structural description, the ostomy bag is hung on a patient in the vertical direction as an example. The washable ostomy bag in this embodiment specifically includes: a chassis 100, a transparent bag body 200, a cleaning portion 300, and a water spraying member 400. The transparent bag body 200 extends a predetermined distance in the vertical direction to form an elongated structure. The chassis 100 is arranged on the upper part of the transparent bag body 200 and can be adhered to the skin surface of the patient. A fistula opening 110 is opened on the chassis 100. The fistula opening 110 is used to be mounted on the outside of the stoma so that excrement in the stoma can flow out into the transparent bag body 200. The transparent bag 200 is detachably or fixedly connected to the chassis 100. A liquid-filling chamber 210 is provided within the transparent bag 200. The liquid-filling chamber 210 communicates with the fistula opening 110, allowing excreta from the stoma to flow into the liquid-filling chamber 210 for storage. A drainage portion 500 is provided at the end of the transparent bag 200 away from the fistula opening 110. The drainage portion 500 is located at the bottom of the transparent bag 200. When excreta flows from top to bottom into the liquid-filling chamber 210 for temporary storage, it can be promptly discharged through the drainage portion 500 when a certain amount is reached. A cleaning portion 300 is provided on the transparent bag 200 and located between the fistula opening 110 and the drainage portion 500. Specifically, the cleaning portion 300 is located on the side of the transparent bag 200, near the bottom of the fistula opening 110. The water spraying member 400 is detachably connected to the cleaning section 300 and extends into the cleaning section 300 to spray cleaning fluid toward the side facing away from the fistula opening 110. When cleaning is required, the water spraying member 400 is connected to the cleaning section 300 and extended into the transparent bag 200. Water is sprayed into the transparent bag 200 to clean the inner wall of the liquid chamber 210. During the cleaning process, excrement residue below the fistula opening 110 is flushed away, preventing wastewater from backflowing and contaminating the stoma. When not in use, the cleaning section 300 is opened, allowing the liquid chamber 210 to communicate with the outside, facilitating ventilation. When ventilation is not required, the cleaning section 300 is closed, sealing the transparent bag 200 so that it can properly contain excrement.

[0039] See also Figure 1 、 Figure 2 、 Figure 3By providing a cleaning portion 300 on the transparent bag 200 and detachably connecting a water spraying member 400 to the cleaning portion 300, the water spraying member 400 extends into the cleaning portion 300 to spray cleaning liquid toward the side facing away from the fistula opening 110, thereby cleaning the liquid-filling chamber 210 within the transparent bag 200. Since the cleaning portion 300 is disposed between the fistula opening 110 and the drain portion 500, when the cleaning liquid is sprayed toward the side facing away from the fistula opening 110, the transparent bag 200 can be cleaned without causing wastewater to be flushed into the fistula opening 110, thereby avoiding the problem of infection of the fistula opening 110 during the cleaning process. Furthermore, the structure is simple, easy to operate, and more convenient in actual use.

[0040] See also Figure 2 、 Figure 3 、 Figure 4 Furthermore, the water spraying member 400 of this embodiment specifically includes: a connecting seat 410 and a shapeable tube 420. The shapeable tube 420 is fixedly mounted on the connecting seat 410, and the connecting seat 410 is detachably connected to the cleaning portion 300. After the connecting seat 410 is connected to the cleaning portion 300, the shapeable tube 420 is inserted into the cleaning portion 300 and the liquid chamber 210. A first nozzle 421 is provided on the end of the shapeable tube 420 that faces away from the connecting seat 410. The shapeable tube body 420 in this embodiment can be a plastic corrugated tube, which can be bent into different shapes and can maintain the shape. Therefore, after the shapeable tube body 420 is inserted into the liquid chamber 210, it can not only spray water downward through the first nozzle 421, but also spray water toward the side wall. Moreover, through the bending of the shapeable tube body 420, it can surround the stoma position half a circle, so that the shapeable tube body 420 can be cleaned in time on the inner wall away from the stoma side through the first nozzle 421. The cleaning water flows downward to the lower part of the liquid chamber 210 along the bent shapeable tube body 420, and basically will not cause pollution to the stoma.

[0041] See also Figure 2 、 Figure 3 、 Figure 4Furthermore, the cleaning portion 300 specifically includes an elastic sleeve 310, which defines a cleaning port 320. The connecting base 410 specifically includes a plug-in tube 411. The elastic sleeve 310 has a certain degree of elasticity and is a rubber sleeve. The plug-in tube 411 is embedded in the cleaning port 320, so that the elastic sleeve 310 is sleeved on the outer wall of the plug-in tube 411. The diameter of the cleaning port 320 is smaller than the plug-in tube 411. This ensures that the plug-in tube 411 and the elastic sleeve 310 form a stable connection due to the elasticity of the rubber, making it difficult for them to separate during the cleaning process. In addition, a cleaning plug is connected to the outer wall of the elastic sleeve 310. The cleaning plug can be folded into or removed from the cleaning port 320, sealing the cleaning port 320 when not cleaning. Due to the stable connection between the elastic sleeve 310 and the plug-in tube 411, the shapeable tube 420 is fixed to the plug-in tube 411, located within the cleaning port 320 and extending into the liquid chamber 210. During the cleaning process, the shapeable tube 420 can swing within a certain range in the liquid-containing cavity 210 , thereby cleaning a wider range of the inner wall of the transparent bag 200 .

[0042] See also Figure 3 、 Figure 4 Furthermore, a limiting groove 321 is defined on the inner wall of the cleaning port 320, and a limiting boss 412 is defined on the outer wall of the insertion tube 411 to match the limiting groove 321. The limiting boss 412 is embedded in the limiting groove 321. The matching of the limiting boss 412 and the limiting groove 321 ensures that the orientation of the shapeable tube 420 is fixed during insertion into the cleaning port 320. This ensures that the spraying direction of the first nozzle 421 is fixed, preventing unskilled users from inserting the shapeable tube 420 into the transparent bag 200, causing the orientation of the first nozzle 421 to be opposite to the standard orientation or misaligned, thereby preventing operational errors that could cause stains to be flushed toward the stoma.

[0043] It is easy to imagine that the limiting boss 412 can also extend to the outer wall of the shapeable tube body 420. During the insertion process of the shapeable tube body 420, it can be limited by the limiting boss 412. In this way, the shapeable tube body 420 can be flushed and cleaned while being inserted, thereby improving the cleaning efficiency and accuracy and making it easier to operate.

[0044] See also Figure 2 、 Figure 6Furthermore, the shapeable tube 420 is provided with a plurality of second nozzles 422. The plurality of second nozzles 422 are spaced apart along the axial direction of the shapeable tube 420, and the orifices of the second nozzles 422 are disposed away from the fistula opening 110. The second nozzles 422 are positioned differently from the first nozzles 421. The plurality of second nozzles 422 are axially disposed on the outer wall of the shapeable tube 420. This allows the second nozzles 422 to clean the inner wall of the transparent bag 200 over a wider range. Furthermore, the entire lower portion of the inner wall of the transparent bag 200 can be cleaned simultaneously at once, providing a more comprehensive cleaning. Furthermore, most of the cleaning water is directed downwards. During the cleaning process, sewage can flow directly out of the drain 500, thereby avoiding the problem of sewage backflow.

[0045] See also Figure 2 、 Figure 6 Furthermore, the openings of the first nozzle 421 and the second nozzle 422 are both configured as tapered openings. The tapered opening design allows the sprayed cleaning liquid to be dispersed to the surrounding area, thereby increasing the cleaning area and covering the entire inner wall of the transparent bag 200 in a short period of time, thereby achieving a more comprehensive cleaning of the inner wall of the transparent bag 200 and improving the cleaning efficiency.

[0046] See also Figure 5 、 Figure 6 Furthermore, a syringe 430 is connected to the connection base 410, and the cleaning fluid is delivered through the syringe 430. The syringe 430 is a commonly used infusion device, and the connection port on the connection base 410 is configured as an interface that matches the syringe 430, thereby allowing the syringe 430 to be connected and easily removed from the syringe 430. Using the syringe 430 to inject the cleaning fluid saves costs, is simple to operate, and is more convenient to use.

[0047] See also Figure 2 、 Figure 5 、 Figure 7Furthermore, the drainage unit 500 includes a first drainage connector 510, which is provided with a first drain plug 511. The first drainage connector 510 is connected to the liquid chamber 210 and is used to cover a first connecting tube 520 for an external urine storage bag 521. When the solution in the liquid chamber 210 reaches a certain amount, it is necessary to drain the solution promptly. Specifically, during the liquid filling stage, the first drain plug 511 is used to seal the first drainage connector 510, thereby sealing the liquid chamber 210 and allowing the liquid chamber 210 to be filled. When draining, the first drainage connector 510 is lifted and bent to seal it. The first drain plug 511 is then removed, and the first connecting tube 520 is inserted. The connection is then connected to the external urine storage bag through the first connecting tube 520. The first drainage connector 510 is then released, so that the first drainage connector 510 is connected to the liquid chamber 210, and the urine in the liquid chamber 210 is drained into the external urine storage bag 521, thereby completing the cleaning process.

[0048] See also Figure 2 、 Figure 7 Furthermore, the diameter of the first connecting tube 520 is 6.5 mm. The first connecting tube 520 of this diameter is a standard connecting tube, and the external urine storage bag 521 connected thereto is a standard product, which is easy to purchase and use and has strong practicality.

[0049] See also Figure 2 、 Figure 5 、 Figure 7 Furthermore, the drainage unit 500 also includes a second drainage connector 530, which communicates with the liquid chamber 210 and is used to fit a drainage hose 540, which is connected to an external storage bag 541. The diameter of the drainage hose 540 is larger than that of the first connecting tube 520. Specifically, a second drain plug 531 can also be connected to the second drainage connector 530 and used in the same manner as the first drain plug 511. While lying in bed, the second drainage connector 530 can be connected to the drainage hose 540, thereby connecting to the external storage bag 541 at the far end. This allows for more excreta to be stored in the external storage bag 541, especially during nighttime use, eliminating the need for frequent replacement and cleaning. Furthermore, excreta is not limited to liquids. By designing the second drainage connector 530 larger, it can divert all large volumes of excreta into the external storage bag 541, making it more convenient to use.

[0050] Furthermore, the diameter of the drainage hose 540 is 20-30 mm. Using a drainage hose 540 of this diameter allows the external storage bag 541 to be placed in a relatively low location, such as under a hospital bed. This allows larger excreta in the liquid chamber 210 to be diverted and discharged into the external storage bag 541, further facilitating the use of the ostomy bag. Furthermore, using a large-diameter drainage hose 540 prevents clogging. Even if the smaller first drainage connector 510 becomes easily clogged, drainage can be achieved through the large-diameter drainage hose 540 without affecting the use of the ostomy bag. Subsequent drainage hoses 540 and external storage bags 541 can be produced as standard consumables, making them more practical.

[0051] For ease of connection, both the first liquid drain connector 510 and the second liquid drain connector 530 may be pagoda connectors.

[0052] In summary, the washable ostomy bag proposed in this application can, during use, after the shapeable tube 420 is inserted into the liquid chamber 210, not only spray water downward through the first nozzle 421, but also spray water toward the side wall. Moreover, the shapeable tube 420 can be bent to surround the stoma half a circle, so that the shapeable tube 420 can be promptly cleaned on the inner wall of the side away from the stoma by the first nozzle 421. The shapeable tube 420 can also be bent into other structures, and the hard-to-reach areas in the transparent bag 200 can be sprayed with water by bending to facilitate the nozzle to reach, thereby achieving comprehensive cleaning of the transparent bag 200. Moreover, the detachable form is adopted, and when not being cleaned, the entire ostomy bag can be used normally without being affected by the water spraying part 400, which makes the use of the ostomy bag more convenient.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
