Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ostomy enema bag. Background Technology

[0002] An ostomy bag is a bag-shaped container used to store urine or fecal matter after a patient has undergone ostomy surgery. When a patient needs an ostomy enema, medical staff remove the ostomy bag before administering the enema, and then reattach the bag to the stoma afterward. This procedure is relatively complex and increases the risk of stoma infection. Furthermore, after the enema is finished and the enema tubing is removed, the enema fluid can easily leak directly from the stoma, soiling bed sheets and the patient's clothing, increasing the burden on medical staff. Therefore, researchers have proposed a device combining an ostomy bag and an enema bag. Taking Chinese utility model patents 202222402238.X and 2021219340301 as examples, a through-hole for a rectal tube is added to the traditional ostomy bag. When an enema is needed, the enema tube is directly inserted through the through-hole into the stoma, allowing the enema to be performed without removing the ostomy bag. After the enema, the enema fluid is directly discharged into the ostomy bag. However, after the enema, the tube inserted into the stoma may retain enema fluid and fecal matter. When the tube is removed from the ostomy bag or during isolation of the tube from the environment, this waste may splash or accidentally come into contact with the patient's or healthcare worker's clothing, or contaminate the surrounding environment, increasing the risk of infection and psychological burden. Therefore, the applicant believes that the current stoma enema device has room for improvement. Utility Model Content

Detailed Implementation

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1 to 5This embodiment provides an ostomy enema bag, including an ostomy bag body 1. The side of the ostomy bag body 1 facing away from the base plate 2 is provided with a first through hole 11 for inserting an anal tube 3. The first through hole 11 is fitted with a storage component. The storage component includes at least a cylindrical body 4 fixed to the ostomy bag body and a foldable storage bag 5 stored in the cylindrical body. The cylindrical body 4 slides and seals with the anal tube 3. The end of the storage bag 5 is provided with a collar 51 that can be fixed to the anal tube 3. When an enema is needed, the anal tube 3, which passes through the first through-hole 11, can be directly inserted into the stoma for the enema operation. After the enema is completed, the enema fluid is directly discharged into the stoma bag body 1. When the anal tube is withdrawn from the stoma bag body 1, the collar 51 is fixed on the anal tube 3. As the anal tube 3 is withdrawn, the storage bag folded inside the cylinder 4 gradually unfolds, isolating and covering the section of the anal tube 3 that has detached from the stoma bag body 1. When the anal tube 3 is completely withdrawn from the stoma bag body 1, the storage bag 5 automatically separates the contaminated anal tube 3 from the surrounding environment to prevent residual enema fluid, feces, and other contaminants on the anal tube 3 from contaminating or splashing onto the patient's or medical staff's clothing, making the stoma enema process more hygienic and convenient.

[0027] In a preferred embodiment, the first through-hole 11 is coaxially arranged with the chassis 2, allowing medical personnel to pull the anal tube 3 back in a straight line, reducing patient discomfort. In some embodiments of this application, the axes of the first through-hole 11 and the chassis 2 may be partially offset, and the anal tube can still be pulled back in a near-straight line. However, to avoid excessive bending of the anal tube within the ostomy bag body during the pull-back process, the axial projections of the first through-hole 11 and the chassis 2 should at least coincide.

[0028] Please see Figure 1 and Figure 3 In one embodiment of the storage bag 5 of this application, in the direction of the longitudinal axis (L) of the storage bag 5, the storage bag 5 includes a plurality of adjacent folded portions 52, each folded portion 52 including a front piece 521 and a rear piece 522 connected to each other, with an inward fold 523 formed between the front piece 521 and the rear piece 522; as Figures 2 to 4 As shown, when the storage bag 5 unfolds as the anal tube 3 is withdrawn, the front piece 521 and the rear piece 522 of the pulled folded part 52 will gradually move towards the inside of the storage bag 5 and will be displaced in the direction of the longitudinal axis (L), thereby covering the anal tube 3 that has been removed from the ostomy bag body 1. The storage bag 5 has a circular cross-section in its length direction, but it is understood that those skilled in the art, based on their understanding of the principles of this application, can adapt the storage bag to other polygonal or composite shapes.

[0029] In a preferred embodiment, within the cavity of the cylindrical body 4 for accommodating the storage bag 5, the storage assembly further includes a control member 6, which abuts against the front piece 521 of the outermost folded portion 52. Along the longitudinal axis (L) of the storage bag 5, an elastic member 7 abuts against the cylindrical body 4. On one hand, the folded storage bag 5 is contained at the bottom of the cavity under the action of the elastic member 7, preventing the storage bag 5 from automatically unfolding. On the other hand, under the force of the elastic member 7, the resistance experienced by the storage bag 5 when unfolding increases, helping to control the unfolding speed of the storage bag 5 and preventing the storage bag 5 from suddenly detaching completely from the cylindrical body 4, thus exposing the contaminated anal canal 3.

[0030] In a preferred embodiment, at least the section of the cylindrical body 4 that mates with the anal tube 3 is a flexible section, so that the flexible section forms a sealed connection with the anal tube 3 when the anal tube 3 passes through the cylindrical body 4; the cavity of the cylindrical body 4 used to accommodate the storage bag 5 is a rigid section, so as to provide a stable support structure.

[0031] As mentioned above, in this embodiment, the first through-hole 11 is coaxially arranged with the chassis 2, allowing medical staff to pull the anal tube 3 back in a straight line. However, this also means that waste discharged from the stoma may splash directly onto the first through-hole 11. Therefore, for the preferred embodiment, please refer to [the previous section]. Figure 1 In a further embodiment of this application, a sealing element 8 is provided inside the cylindrical body 4 or at the first through hole 11 on the ostomy bag body 1 along the longitudinal axis (L) of the storage bag 5. The sealing element 8 is a rubber component with a slit. When the anal tube 3 is detached from the ostomy bag body, the rubber component automatically resets to form a seal, thereby further enhancing the sealing and leak-proof properties of the ostomy bag body 1. More specifically, the slit is cross-shaped, which facilitates the passage of the anal tube and helps the sealing element quickly return to its original position. Furthermore, in some embodiments of this application, the slit can also be other straight slits, such as V-shaped or straight.

[0032] As a preferred embodiment, an elastic pull strap 9 is attached to the collar 51. The pull strap 9 partially tightens the collar in its natural contraction state to ensure a tight fit between the collar 51 and the anal tube 3 during enema, thereby enhancing the sealing of the tube 4. When the enema is finished and the anal tube 3 needs to be pulled back, the pull strap 9 can be pulled to further tighten and fix the collar to the anal tube 3.

[0033] In a preferred embodiment, the cylindrical body 4 and the ostomy bag body 1 are detachable to enhance the ease of use of the device. Furthermore, the ostomy bag body 1 is provided with an end seat 10 communicating with the first through hole 11. The end seat 10 has external threads, and the cylindrical body 4 can be threadedly connected to the end seat 10 via these external threads. In this way, the cylindrical body 4 can be pre-installed on the ostomy bag body 1, or installed after the patient has worn the ostomy bag body 1, allowing for more flexible adjustments to meet different situations or individual needs. On the other hand, this method allows the cylindrical body 4 to be removed after the storage bag 5 separates the contaminated anal tube 3 from the surrounding environment, enabling safe disposal or replacement of the contaminated cylindrical body and ensuring hygiene and safety. Furthermore, the end seat 10 is also equipped with an end cap 12, which seals the first through hole 11 after the cylindrical body 4 is disassembled, ensuring the airtightness of the ostomy bag body 1.

[0034] Example 2: A bag body includes a collection bag and a flushing bag (not shown in the figure) for injecting liquid. The flushing bag is connected to a drainage tube. The collection bag can be an ostomy bag for collecting waste discharged from the stoma, but is not limited to an ostomy bag. The drainage tube can be a rectal tube for enema drainage, but is not limited to a rectal tube. The collection bag has a first through hole for the drainage tube to pass through. The first through hole is fitted with a storage component. The storage component includes at least a cylindrical body fixed to the collection bag and a foldable storage bag stored in the cylindrical body. The cylindrical body is slidably fitted with the drainage tube. The end of the storage bag is provided with a collar that can be fixed to a guide tube.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
