DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0018] Embodiment 1 Figure 1 FIG. 1 shows a schematic diagram of the structure of the ostomy bag provided in this embodiment. Figure 2 The structural schematic diagram of the sealing structure of the ostomy bag provided in this embodiment is shown. Figure 3 shows a cross-sectional view of the sealing structure provided in this embodiment, Figure 4 FIG. 1 shows a schematic diagram of the structure of the adapter ring 1 provided in this embodiment. Figure 1-Figure 4 As shown, this embodiment provides an ostomy bag, which includes a bag body 6 having a bag cavity and used to collect excrement, and a connecting component (such as an adhesive surface with an opening) provided on the bag body 6 and used to connect the bag body 6 to the stoma of the patient. If the bag body 6 cannot be firmly fixed on the patient's body, the ostomy bag may also include a fixing component, such as a belt, provided on the bag body 6 and used to fix the bag body 6 on the patient's body. It should be noted that the bag body 6, the connecting component and the fixing device can be conventional structures of ostomy bags in the prior art, which should be known to those skilled in the art, so they will not be described in detail here.

[0019] The ostomy bag also includes a sealing structure disposed on the bag body 6 and connected to the bag cavity. The sealing structure of the ostomy bag includes an adapter ring 1, a multifunctional cover 2, and a filter sheet 3. The adapter ring 1 is fixedly disposed on the bag body 6 and has a flushing hole 11 connected to the bag cavity. The multifunctional cover 2 includes a first cover body 21 detachably covered on the adapter ring 1 and having a channel 211, and a second cover body 22 detachably covered on the first cover body 21 and having an exhaust hole 221, and a cover cavity 23 formed between the first cover body 21 and the second cover body 22 and capable of sequentially connecting the bag cavity and the outside through the channel 211 and the exhaust hole 221. The filter sheet 3 is disposed in the cover cavity 23 and can filter the gas in the bag cavity when the exhaust hole 221 exhausts the gas.

[0020] When the patient needs to flush the bag body 6, the patient can remove the multifunctional cover 2 from the adapter ring 1. At this time, the flushing hole 11 of the adapter ring 1 is exposed. The patient can use the flushing hole 11 exposed on the adapter ring 1 to facilitate the cleaning equipment to inject clean water into the bag cavity to complete the comprehensive cleaning of the bag body 6. When the patient completes the flushing operation or the ostomy bag is in daily use, the patient can install the multifunctional cover 2 on the adapter ring 1 again and block the flushing hole 11. At this time, the gas in the bag cavity can be discharged to the outside through the bag cavity, the channel 211, the filter 3 in the cover cavity 23 and finally discharged to the outside through the exhaust hole 221, so that the gas accumulated in the bag cavity can be released smoothly, effectively avoiding the occurrence of bag bulging, thereby ensuring the patient's comfortable experience. As time goes by, the filtering effect of the filter 3 will gradually weaken. At this time, the cover cavity 23 can be exposed by removing the second cover body 22 of the multifunctional cover 2 from the first cover body 21 of the multifunctional cover 2, so that a new filter 3 can be placed in it for filtering.

[0021] The ostomy bag provided in this embodiment innovatively integrates the exhaust function and flushing function required by the ostomy bag into a sealing structure on the bag body 6, so that the patient can achieve the above functions by performing multiple operations on only one sealing structure, which is more convenient for the patient to perform exhaust, flushing and other operations. Compared with the prior art, the overall structure of the ostomy bag is simplified, the production cost and manufacturing complexity of the ostomy bag are reduced, thereby ensuring that the patient enjoys an excellent user experience and effectively reducing the difficulty of producing the ostomy bag.

[0022] Furthermore, a first annular groove 222 is provided at the edge of the second cover body 22 on one side close to the first cover body 21, and a first annular clamp 212 is provided at the edge of the first cover body 21 on one side close to the second cover body 22. The first annular groove 222 includes a first outer clamping protrusion 2221 and a first inner clamping protrusion 2222 that are spaced apart from each other, and the first annular clamp 212 includes a second outer clamping protrusion 2121 and a second inner clamping protrusion 2122 that are spaced apart from each other. When the first annular clamp 212 is inserted into the first annular groove 222, the first outer clamping protrusion 2221 and the first inner clamping protrusion 2222 of the first annular groove 222 are respectively abutted against the second outer clamping protrusion 2121 and the second inner clamping protrusion 2122 of the first annular clamp 212 and are used to prevent the first annular clamp 212 from actively withdrawing from the first annular groove 222. The first outer latching protrusion 2221 abuts against the second outer latching protrusion 2121, and the first inner latching protrusion 2222 abuts against the second inner latching protrusion 2122, so that after the first annular clamp 212 is inserted into the first annular clamping groove 222, both the inner and outer sides of the first annular clamp 212 (i.e., the inner side located at the cover cavity 23 and the outer side located at the outside) form a clamping connection with the first annular clamping groove 222, which can facilitate the installation of the second cover body 22 on the first cover body 21 or the removal of the second cover body 22 from the first cover body 21. Compared with the traditional single-sided clamping fixing method, the double-sided clamping can make the second cover body 22 more secure when it is covered on the first cover body 21, so as to prevent the multi-functional cover 2 from collapsing when it is removed from the adapter ring 1. Moreover, the fixing method in which both the inner and outer sides of the first annular clamping head 212 are clamped with the first annular clamping groove 222 can make the second cover 22 and the first cover 21 fit more closely compared to the conventional single-sided clamping fixing method, so that the liquid in the bag cavity can be better prevented from penetrating from the connection position between the second cover 22 and the first cover 21, thereby improving the sealing performance of the multifunctional cover 2. Furthermore, compared to the single-sided clamping fixing method, the double-sided clamping fixing method can disperse the force when the second cover 22 and the first cover 21 are connected to the inner and outer sides during long-term use, thereby improving the service life of the multifunctional cover 2.

[0023] Furthermore, a first notch 2123 is provided at the root of the second outer clamping protrusion 2121 for facilitating its entry and exit into the first annular clamping groove 222, a first chamfered surface 2124 is provided at the head of the second outer clamping protrusion 2121 for facilitating its entry and exit into the first annular clamping groove 222, a second notch 2125 is provided at the root of the second inner clamping protrusion 2122 for facilitating its entry and exit into the first annular clamping groove 222, and a second chamfered surface 2126 is provided at the head of the second inner clamping protrusion 2122 for facilitating its entry and exit into the first annular clamping groove 222. Since the second outer clamping protrusion 2121 and the second inner clamping protrusion 2122 are almost similar in structure, only the matching process of the second inner clamping protrusion 2122 and the first inner clamping protrusion 2222 is described as an example. When the second cover 22 is installed on the first cover 21 (i.e., the first annular clamp head 212 enters the first annular clamp groove 222), the second chamfered surface 2126 can guide the moving direction of the first inner clamping protrusion 2222, so that the first inner clamping protrusion 2222 is deformed to cause the first annular clamp groove 222 to expand, thereby facilitating the entry of the first annular clamp head 212. When the first inner clamping protrusion 2222 moves to the position of the second notch 2125, the first inner clamping protrusion 2222 squeezes the second inner clamping protrusion 2122, causing the second notch 2125 to shrink, so as to cause the first inner clamping protrusion 2222 to quickly abut against the second inner clamping protrusion 2122, thereby facilitating the entry of the first annular clamp head 212, thereby saving the patient time to install the second cover 22 on the first cover 21, and saving more effort, thereby improving the patient's user experience.

[0024] Figure 5 FIG. 2 shows a schematic diagram of the structure of the second cover body 22 provided in this embodiment. Figure 5 Combined with Figure 1-Figure 4As shown, the multifunctional cover 2 also includes an annular protrusion 24 disposed on the second cover body 22 and in the cover cavity 23, and the vent hole 221 is located radially outside the annular protrusion 24. When the second cover body 22 covers the first cover body 21, the end of the annular protrusion 24 close to the first cover body 21 is a corrugated shape with a trough structure 242 having a peak structure 241 and can be pressed into the filter plate 3, and the maximum depth of the peak structure 241 pressed into the filter plate 3 does not exceed 1 / 2 times the thickness of the filter plate 3. The annular protrusion 24 on the second cover body 22 is pressed into the filter plate 3, so that the part of the filter plate 3 pressed by the annular protrusion 24 can have a higher waterproof performance, which can better prevent the liquid from the bag body 6 from passing through this place and flowing out through the vent hole 221. At the same time, since the maximum depth of the annular protrusion 24 pressed into the filter plate 3 does not exceed 1 / 2 times the thickness of the filter plate 3, this method prevents the part of the filter plate 3 pressed by the annular protrusion 24 from completely losing its air permeability, thereby ensuring that the exhaust function of the vent hole 221 is still effective. It can be seen that the sealing structure not only preserves the exhaust function of the exhaust hole 221, but also reduces the possibility of the liquid in the bag body 6 penetrating through the exhaust hole 221, thereby reducing the possibility of the liquid in the bag cavity contaminating clothes or sheets, and even causing infection, which can effectively improve the user experience. The peak structure 241 of the annular protrusion 24 is the structure of the maximum depth of the filter plate 3 pressed into the annular protrusion 24, and the trough structure 242 of the annular protrusion 24 is also pressed into the filter plate 3, but it is less than the depth of the peak structure 241 pressed into the filter plate 3. Through a lot of research and experimental verification, this corrugated shape not only ensures that the part where the filter plate 3 is pressed into has a higher waterproof performance, thereby better preventing the liquid from the bag body 6 from passing through this place and flowing out through the exhaust hole 221, but also ensures that the part where the filter plate 3 is pressed into has better air permeability, so that the exhaust hole 221 can release the gas accumulated in the bag cavity in time, effectively avoiding the occurrence of bag bulging.

[0025] Figure 6 FIG. 2 shows a schematic diagram of the structure of the first cover body 21 provided in this embodiment. Figure 6 Combined with Figure 1-Figure 5As shown, the cover cavity 23 includes a first portion 231 formed in the first cover body 21 and connected to the channel 211, and a second portion 232 formed in the second cover body 22 and connected to the exhaust hole 221, wherein the first portion 231 includes a receiving groove 2311 for accommodating the filter plate 3, and a buffer groove 2312 arranged at the bottom of the receiving groove 2311 and inserted into the flushing hole 11 of the adapter ring 1, and the buffer groove 2312 can store the liquid in the bag body 6 before it flows into the receiving groove 2311 through the channel 211, so as to slow down the flow of the liquid into the receiving groove 2311, thereby further improving the anti-water seepage effect of the ostomy bag. The radial dimension of the receiving groove 2311 is larger than the radial dimension of the buffer groove 2312, but smaller than the inner diameter of the annular protrusion 24, so that when the annular protrusion 24 squeezes the filter plate 3, it can keep the filter plate 3 close to the bottom of the receiving groove 2311 and keep the filter plate 3 blocking the buffer groove 2312, thereby preventing part of the gas from escaping from the gap between the filter plate 3 and the bottom of the receiving groove 2311, thereby ensuring that the filter plate 3 can effectively filter the gas discharged through the channel 211, the buffer groove 2312, the receiving groove 2311 and the exhaust hole 221.

[0026] Preferably, the number of channels 211 is also multiple, and multiple channels 211 can allow more gas in the bag cavity to enter the buffer groove 2312 and the containing groove 2311, and multiple channels 211 can also reduce the occurrence of the situation where the gas cannot be discharged due to the blockage of the channel 211. Multiple channels 211 are evenly arranged on the first cover body 21 along the circumferential direction, and the central axis of each channel 211 is arranged obliquely relative to the central axis of the flushing hole 11, and the end of each channel 211 close to the second cover body 22 is farther away from the central axis of the flushing hole 11 than the end away from the second cover body 22. The inclined channel 211 can use the effect of gravity to make the liquid flow more smoothly, avoid accumulation in the channel 211, and cause the blockage of the channel 211, so as to reduce the situation where the gas cannot be discharged due to the blockage of the channel 211.

[0027] Furthermore, a plurality of circumferentially distributed guide notches 213 are provided at the junction of the bottom of the receiving groove 2311 and the top of the buffer groove 2312. The plurality of guide notches 213 are coaxial with the plurality of channels 211. When liquid accumulates in the first part 231 of the cover cavity 23, the plurality of guide notches 213 can guide the liquid in the receiving groove 2311 to flow back into the buffer groove 2312 to avoid flowing out through the exhaust hole 221.

[0028] Furthermore, the connection between the adapter ring 1 and the first cover body 21 is a snap-on connection, so as to achieve the effect of quick disassembly and installation on the basis of establishing a detachable connection relationship between the adapter ring 1 and the first cover body 21. Exemplarily, the snap-on connection between the adapter ring 1 and the first cover body 21 can be set as a double-sided snap-on connection such as a convex snap-on connection between the second cover body 22 and the first cover body 21. The ostomy bag also includes a handle structure 4 connected to the first cover body 21 and used to release the snap-on connection between the first cover body 21 and the adapter ring 1. The patient can easily pull the first cover body 21 with the help of the handle structure 4, so that the first cover body 21 and the second cover body 22 are separated from the adapter ring 1 together, so that the patient can remove the multifunctional cover 2 from the adapter ring 1. Exemplarily, the handle structure 4 is a sheet-like structure connected to the first cover body 21, so that the patient can lift it.

[0029] Preferably, the ostomy bag also includes a connecting strip 5, one end of which is connected to the first cover body 21, and the other end is connected to the second cover body 22. The second cover body 22 is connected to the first cover body 21 through the connecting strip 5 to prevent the second cover body 22 from being lost after being removed from the first cover body 21 when replacing the filter 3.

[0030] Preferably, the filter sheet 3 includes activated carbon or bamboo charcoal, and the activated carbon or bamboo charcoal has a strong adsorption capacity to adsorb various substances with odor in the gas in the bag cavity to achieve the effect of purifying the gas. The multifunctional cover 2 is made of plastic or rubber, and the first cover body 21 and the second cover body 22 can be deformed by utilizing the deformation characteristics of plastic and rubber, thereby achieving snap connection.

[0031] Embodiment 2 The ostomy bag provided in this embodiment is basically the same as that in the first embodiment. The difference between the ostomy bag provided in this embodiment and that in the first embodiment is that: Figure 7 FIG. 4 shows a cross-sectional view of the sealing structure provided in this embodiment. Figure 7 Combined with Figure 1-Figure 6 As shown, in the present embodiment, a first annular groove 222 is provided at the edge of the second cover body 22 on the side close to the first cover body 21, and a first annular clamp 212 is provided at the edge of the first cover body 21 on the side close to the second cover body 22. The first annular groove 222 includes a first outer clamping protrusion 2221 and a first inner clamping protrusion 2222 which are spaced apart from each other, and the first annular clamp 212 includes a second inner clamping protrusion 2122. When the first annular clamp 212 is inserted into the first annular groove 222, the first outer clamping protrusion 2221 of the first annular groove 222 abuts against the edge of the first cover body 21 away from the second cover body 22, and the first inner clamping protrusion 2222 of the first annular groove 222 abuts against the second inner clamping protrusion 2122 of the first annular clamp 212 to prevent the first annular clamp 212 from actively withdrawing from the first annular groove 222.

[0032] The first outer clamping protrusion 2221 abuts against the edge of the first cover body 21 away from the second cover body 22, and the first inner clamping protrusion 2222 abuts against the second inner clamping protrusion 2122, so that after the first annular clamping head 212 is inserted into the first annular clamping groove 222, both the inner and outer sides of the first annular clamping head 212 (i.e., the inner side of the cover cavity 23 and the outer side of the outside) are clamped with the first annular clamping groove 222, which can facilitate the installation of the second cover body 22 on the first cover body 21 or the removal of the second cover body 22 from the first cover body 21. Since the first outer clamping protrusion 2221 abuts against the edge of the first cover body 21 away from the second cover body 22, when the second cover body 22 is removed, the first outer clamping protrusion 2221 needs to produce a larger deformation relative to the second cover body 22 before it can be removed. Therefore, the first outer clamping protrusion 2221 provided in this embodiment is more secure and has better sealing performance than the first outer clamping protrusion 2221 provided in the first embodiment.
