Description

Technical Field

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

[0002] An ostomy bag, also called an enterostomy bag, is a device used to cover and collect secretions from the intestines or urethra. It is usually used for patients who have undergone ostomy surgery, which involves exposing part of the intestines or urethra through the abdominal skin to form an opening called a "stomach". Patients excrete waste through this opening. Because the intestinal contents produce gas during excretion, an air venting filter is used to prevent the ostomy bag from bulging.

[0003] Current ostomy bag exhaust filter consists of an activated carbon filter with adhesive strips on both sides and a sealing tape. The filter has a through hole in the middle. When using it, the filter is simply pasted onto the appropriate position on the ostomy bag, then a needle is used to pierce the stoma strap through the through hole, and finally the through hole is sealed with the sealing tape. It is relatively simple to use. However, the activated carbon filter will gradually become saturated during the continuous filtration of turbid gas, resulting in a decrease in filtration performance. The existing technology does not consider the replacement of the filter. The ostomy bag may be damaged when the activated carbon filter is torn off. Therefore, an ostomy bag with an exhaust filter is proposed. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale.

[0023] Reference Figures 1-3This invention provides an ostomy bag with an exhaust filter, comprising an ostomy bag body 1, an installation plate 2 fixedly connected to the outside of the ostomy bag body 1, an activated carbon filter 4 rotatably mounted on the top of the installation plate 2, and an openable and closable cover 3 pressing on the top of the activated carbon filter 4. The cover 3 is hinged to the ostomy bag body 1 and is locked when closed. An eccentric hole 2a is provided on the top of the installation plate 2 to allow turbid gas to pass through the activated carbon filter 4. The eccentric hole 2a is located below the cover 3. When the cover 3 is closed, it does not completely block the activated carbon filter 4. The turbid gas passes through the ostomy bag body 1, the installation plate 2, the eccentric hole 2a, and the activated carbon filter 4 in sequence, and is discharged from the part of the activated carbon filter 4 that is not blocked by the cover 3. The activated carbon filter 4 filters the turbid gas.

[0024] like Figure 2 and Figure 3 As shown, a humidity indicator 5 of the same size is fixedly connected to the top of the activated carbon filter 4. The humidity indicator 5 is a paper material specifically used to indicate changes in ambient humidity. It displays the current humidity level through color changes and usually contains humidity-sensitive chemicals. This is existing technology and will not be described in detail. The humidity indicator 5 is attached to the activated carbon filter 4, which can indirectly reflect the filtration performance of the activated carbon filter 4 and also seal the top of the activated carbon filter 4, so that the turbid gas can only be discharged through the side of the activated carbon filter 5, thereby increasing the exhaust path of the turbid gas and improving the filtration effect. When the cover 3 is closed, it presses down the humidity indicator 5. The cover 3 has an observation hole 3a that coincides with the axis of the eccentric hole 2a.

[0025] like Figure 3 As shown. A positioning post 6 is also fixedly connected to the top of the mounting plate 2. The activated carbon filter sheet 4 is ring-shaped and is fitted onto the positioning post 6. The height of the positioning post 6 is less than the thickness of the activated carbon filter sheet 4. The top edge of the positioning post 6 is chamfered. The chamfer is used to facilitate fitting the activated carbon filter sheet 4 onto the positioning post 6. The positioning post 6 and the mounting plate 2 are integrally formed. The integral forming can reduce processing costs and enhance structural strength.

[0026] like Figure 3 As shown, connecting blocks 7 made of elastic material are fixedly connected to the bottom of both sides of the cover 3. Smooth and rounded positioning blocks 8 are fixedly connected to the inner side of both sets of connecting blocks 7. Grooves are provided on both sides of the mounting plate 2. Positioning holes 2b matching the positioning blocks 8 are opened on the inner side of both sets of grooves. When the cover 3 is closed, the two sets of connecting blocks 7 are inserted into the two sets of grooves respectively, and the two sets of positioning blocks 8 are engaged in the two sets of positioning holes 2b respectively.

[0027] Working principle: During use, the turbid gas in the ostomy bag 1 passes sequentially through the mounting plate 2, eccentric hole 2a, and activated carbon filter 4, and then exits from the edge of the activated carbon filter 4. The activated carbon filter 4 filters the turbid gas. During the continuous filtration of turbid gas, the activated carbon filter 4 gradually becomes saturated, resulting in a decrease in filtration efficiency and an inability to effectively filter the moisture in the turbid gas. When the moisture comes into contact with the humidity indicator 5, it causes the humidity indicator 5 to change color. By observing the color of the humidity indicator 5 through the observation hole 3a, it is possible to indirectly determine whether the filtration performance of the activated carbon filter 4 has decreased. If the performance has decreased, the part of the humidity indicator 5 exposed outside the cover 3 can be moved to rotate the humidity indicator 5 and the activated carbon filter 4. The observation hole 3a can be observed. When the humidity indicated by the humidity indicator 5 in the observation hole 3a is low, the movement of the humidity indicator 5 can be stopped, and turbid gas filtration can continue.

[0028] When replacing the humidity indicator 5, flip the cover 3 upwards. The two sets of connecting blocks 7 will deform, and the two sets of positioning blocks 8 will disengage from the corresponding positioning holes 2b. At this time, the cover 3 will open, and the activated carbon filter 4 and humidity indicator 5 can be directly taken out for replacement. After replacement, the cover 3 will be put back on, and the device can continue to be used.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
