Abstract
Description
Technical Field
[0001] This application relates to the field of ostomy bag technology, and in particular to an enterostomy enema irrigation device. Background Technology
[0002] Ostomy bags are containers used to store human excrement. Ostomy bags can generally be divided into closed-type and open-type. For semi-formed stool or liquid stool that can be emptied frequently as needed, open-type ostomy bags are more suitable.
[0003] Stoma enema refers to the infusion of a suitable amount of liquid through the stoma using a specific method to help patients cleanse their intestines, defecate, expel gas, or receive medication via the intestines, achieving therapeutic and cleansing purposes. Closed ostomy bags, lacking an irrigation port, require cutting an opening in the bag body, which may lead to leakage, making them less suitable for stoma enema. Open ostomy bags, with their bottom and exterior connected, are typically used for ostomy enema by manually pinching or binding the opening with adhesive tape. However, these operations may result in incomplete sealing and leakage. Utility Model Content
[0004] The technical problem to be solved by this application is to provide an enterostomy enema irrigation device that can prevent leakage from the ostomy bag.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0006] An enterostomy enema irrigation device includes an ostomy bag with an open bottom, a three-lumen tube inside the ostomy bag, and a sealing assembly located at the bottom of the ostomy bag, including a fixing collar, a sealing block inside the fixing collar, a through hole in the middle of the sealing block for the three-lumen tube to pass through, and a sleeve cylinder at the bottom of the sealing block, the bottom of the sleeve cylinder being sealed to the three-lumen tube.
[0007] Further expanding upon the above scheme, the three-lumen tube includes a negative pressure suction tube, a fixing tube, and a flushing tube, with the negative pressure suction tube and the flushing tube respectively having a drainage hole and a flushing hole.
[0008] To facilitate flushing and drainage, the above scheme is further expanded by opening the flushing hole at the top of the flushing tube; the drainage hole is opened on the side wall of the negative pressure suction tube and located at the opening at the bottom of the ostomy bag.
[0009] To facilitate adjustment of the length of the three-cavity tube, the above scheme is further expanded, and the sleeve cylinder includes a sleeve ring and a sleeve cover. The sleeve ring and the sleeve cover are connected by threads, and a through hole is opened in the middle of the sleeve cover.
[0010] Further extending the above scheme, the three-lumen tube passes through the through hole of the sleeve cover and is sealed to the through hole.
[0011] Compared with the prior art, this application achieves at least the following beneficial effects: This flushing device installs the sealing component at the bottom of the open ostomy bag, and seals the bag opening of the ostomy bag by means of a fixing collar and a sealing block; the sleeve cylinder on the sealing block allows the three-lumen tube to pass through, and can seal the three-lumen tube after adjusting the length of the three-lumen tube entering the stoma. Compared with the existing methods of cutting openings on closed ostomy bags and manually pinching or binding the opening of open ostomy bags with tape, this device seals the bag opening of the open ostomy bag tightly, preventing leakage at the bag opening.

Detailed Implementation
[0019] The present application will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.
[0020] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this application.
[0021] To address the defect of leakage from ostomy bags in existing technologies. After careful analysis, the inventors discovered that the main reason for the above problems lies in the fact that ostomy bags are generally divided into closed-mouth and open-mouth types. Closed-mouth ostomy bags do not have an opening for the irrigation tube to enter the stoma for irrigation. Therefore, an opening must be cut in the bag to insert the irrigation tube into the ostomy bag. However, the cut opening and the irrigation tube are not sealed, and the oozing liquid may leak out from the cut opening due to splashing or overflow. Open-mouth ostomy bags are usually open at the bottom. Therefore, the irrigation tube can be inserted into the stoma from the bottom of the open-mouth ostomy bag. However, the opening of the open-mouth ostomy bag is relatively large, and there is no structure to seal the ostomy bag after the irrigation tube is inserted. Therefore, it can only be sealed by manually pinching the bag opening or by binding the bag opening with tape. This method still leaves a certain gap in the ostomy bag, and liquid may leak out from the gap at any time. Of course, the opening of the ostomy bag can also be bent to prevent leakage. However, after bending, the volume of the bag is reduced. When there is a lot of liquid, it may flow back into the stoma, posing a risk of backcontamination. Based on the above analysis, the inventors made structural improvements to the enterostomy enema irrigation device.
[0022] Example 1
[0023] like Figure 1 , 2 As shown, in one embodiment of the enterostomy enema irrigation device of this application, the device includes an ostomy bag 1 with an open bottom, a three-lumen tube inside the ostomy bag 1, and a sealing assembly located at the bottom of the ostomy bag 1. The sealing assembly includes a fixing ring 5 made of plastic, which is fitted over the outside of the bag opening 11 of the ostomy bag 1. A sealing block 6 is installed inside the fixing ring 5. The sealing block 6 is arranged inside the bag opening 11 of the ostomy bag 1. The bag opening 11 of the ostomy bag 1 is compressed and sealed by the cooperation of the fixing ring 5 and the sealing block 6. The bottom of the sealing block 6 has an outward flange. The flange serves two purposes: first, to increase the sealing area of the bag opening 11, and second, to prevent the sealing block 6 from sinking too deeply when installed in the fixing ring 5. A through hole for the three-lumen tube to pass through is opened in the middle of the sealing block 6. A sleeve cylinder 7 is provided at the bottom of the sealing block 6. The bottom of the sleeve cylinder 7 is sealed and connected to the three-lumen tube.
[0024] The three-lumen tube includes a negative pressure suction tube 2, a fixing tube 3, and a flushing tube 4. The negative pressure suction tube 2 and the flushing tube 4 are respectively provided with a drainage hole 21 and a flushing hole 41. The three-lumen tube structure can be modified from an existing three-lumen urinary catheter using readily available materials. Specifically, a drainage hole 21 is made in the tubing of the inflatable balloon, forming the drainage tube. The tubing used for medication instillation or bladder irrigation is retained as the flushing tube. The top opening of the urinary catheter is sealed to form the fixing tube 3. Flushing the fixing tube 3 with water provides the three-lumen tube with sufficient strength, preventing it from swaying due to its flexibility.
[0025] The irrigation hole should be located at the top or upper middle side wall of the irrigation tube 4, so that the cleaning fluid can enter the enterostomy along the top of the irrigation tube 4, reducing the depth of the three-lumen tube into the enterostomy and reducing the patient's discomfort; the drainage hole 21 is located on the side wall of the negative pressure suction tube 2, and at the opening at the bottom of the ostomy bag 1, above the sealing block 6, so that the drainage hole 21 can draw out most of the waste fluid in the ostomy bag 1.
[0026] The sleeve cylinder 7 includes a sleeve ring 71 and a sleeve cover 72, which are connected by threads. A through hole is provided in the center of the sleeve cover 72, and a three-lumen tube passes through and is sealed to the through hole. For example... Figure 2 As shown, the top of the sleeve ring 71 is connected to the bottom of the sealing block 6. The bottom of the sleeve ring 71 is provided with an inner flange 711. The structure of the sleeve cap 72 is similar to that of a mineral water bottle cap. A sealing gasket is provided between the inside of the sleeve and the inner flange 711. The inner wall of the sleeve cap 72 and the rubber gasket 8 are in contact with the outer wall of the three-lumen tube, and the sleeve cap 72 and the rubber gasket 8 can be moved on the three-lumen tube by pulling them. After determining the insertion length of the three-lumen tube, the sleeve cap 72 and the rubber gasket 8 are moved to the designated position on the three-lumen tube, and the sleeve cap 72 is screwed onto the thread of the sleeve ring 71. The inner wall of the sleeve cap 72 and the bottom surface of the inner flange 711 of the sleeve ring 71 will compress and deform the rubber gasket 8, so that the inner wall of the rubber gasket 8 and the outer wall of the three-lumen tube are in close contact to form a seal, while preventing the three-lumen tube from moving.
[0027] In use, first install the opening at the bottom of the ostomy bag 1 between the fixing ring 5 and the sealing block 6 to seal the ostomy bag 1. Then, put the sleeve cap 72 and the rubber gasket 8 onto the three-lumen tube. After determining the insertion length of the three-lumen tube, screw the sleeve cap 72 onto the sleeve ring 71. As mentioned before, a seal is formed by squeezing the contact between the rubber gasket 8 and the three-lumen tube, and flushing can then be performed. After flushing, the negative pressure suction tube 2 drains the waste fluid out of the ostomy bag 1 through the drainage port. After drainage is complete, the sealing device can be turned upside down, and the sleeve cap 72, sealing block 6, and fixing ring 5 can be removed in sequence for cleaning and disinfection for reuse.
[0028] Example 2
[0029] Considering that there may be situations where the inside of the ostomy bag 1 needs to be rinsed and cleaned after the enterostomy has been flushed and the waste fluid has been drained, this embodiment sets the three-lumen tube to be movable up and down, which can flexibly adjust the position of the flushing hole inside the ostomy bag 1, which is beneficial for cleaning the ostomy bag 1.
[0030] The difference from Example 1 is that, as Figure 3-5 As shown, the drainage hole 21 is located at the top of the negative pressure suction tube 2.
[0031] The bottom of the sealing block is connected to a telescopic tube 9, which should preferably be a corrugated pipe.
[0032] An adjusting sleeve 10 is provided at the through hole of the sleeve cover 72. There is a gap between the sleeve cover 72 and the adjusting sleeve 10. The top of the adjusting sleeve 10 and the bottom of the telescopic tube 9 are sealed together. The top surface of the adjusting sleeve 10 is provided with a flange to prevent it from coming out of the sleeve cover 72.
[0033] The bottom of the adjusting sleeve 10 is provided with a sealing cover 12. The adjusting sleeve 10 and the sealing cover 12 are connected by threads. The adjusting sleeve 10 and the sealing cover 12 are in contact with the inner wall of the three-chamber tube. A through hole is opened in the middle of the sealing cover 12. Figure 5 As shown, a rubber gasket 8 (smaller in size) is provided between the adjusting sleeve 10 and the sealing cap 12, similar to that mentioned in Embodiment 1. The inner wall of the rubber gasket 8 in this embodiment also contacts the outer wall of the three-lumen tube. The three-lumen tube of the required length is inserted through the through hole of the sealing cap 12, and after passing through the telescopic tube 9 into the ostomy bag 1, the sealing cap 12 is screwed onto the adjusting sleeve 10. The bottom surface of the adjusting sleeve 10 and the inside of the sealing cap 12 will compress and deform the rubber gasket 8, making the inner wall of the rubber gasket 8 and the outer wall of the three-lumen tube come into close contact to form a seal, while preventing the three-lumen tube from moving.
[0034] This embodiment utilizes the internal space of the sleeve cylinder 7 in Embodiment 1. Specifically, to accommodate the longer telescopic tube 9, the length of the sleeve ring 71 is extended in this embodiment.
[0035] In use, first install the opening at the bottom of the ostomy bag 1 between the fixing ring 5 and the sealing block 6 to seal the ostomy bag 1. At this time, the connecting cap 72 is already threaded onto the connecting ring 71. After inserting the three-lumen tube into the adjusting sleeve 10, tighten the sealing cap 12. As mentioned above, a seal is formed by squeezing the contact between the rubber gasket 8 and the three-lumen tube, and flushing can then be performed. After flushing, unscrew the connecting cap 72. The connecting cap 72 is not connected to the connecting ring, and the telescopic tube 9 can be extended. When extended, the top of the three-lumen tube moves away from the ostomy opening toward the bag opening 11 of the ostomy bag 1, and the waste fluid is led out through the negative pressure suction tube 2. Then, the inside of the ostomy bag 1 can be cleaned by moving the three-lumen tube up and down and spraying cleaning fluid from the flushing hole. After cleaning, screw the sleeve cap 72 back onto the sleeve ring 71, and squeeze and fold the telescopic tube 9. The waste fluid inside is squeezed into the ostomy bag 1. At this time, the sealing device can be turned upside down, and the sleeve cap 72, sealing block 6 and fixing ring 5 can be removed in sequence. Finally, the remaining waste fluid can be removed from the ostomy bag 1.
[0036] During use, the sealing device tightly seals the opening 11 of the ostomy bag 1, preventing leakage at the opening 11.
[0037] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
