[0037] The present application provides an ostomy bag, Figures 1 to 6 An embodiment of the ostomy bag provided by the present application is provided.

[0038] Please refer to Figures 1 to 2The stomal pouch 100 comprises a pouch body 1 and an exhaust structure 2, wherein the pouch body 1 is formed with a cavity, the exhaust structure 2 comprises a ring body 21 connected to the pouch body 1, and a blocking body 22 capable of being arranged in the ring body 21 and movable relative to the ring body 21, the blocking body 22 has a first position and a second position on the movable stroke of the blocking body 22, in the first position, the blocking body 22 and the ring body 21 are in sealing fit, in the second position, an exhaust passage is formed between the blocking body 22 and the ring body 21, one end of the exhaust passage is capable of communicating with the cavity, and the other end communicates with the outside.

[0039] The pouch body 1 of the stomal pouch 100 is divided into a urinary pouch and an anorectal fistula pouch, the anorectal fistula pouch is used for collecting intestinal excrement, such as Figure 1 Considering the properties and odor of feces, the anorectal fistula pouch has unique features in capacity and odor prevention design, the pouch body has relatively large capacity to accommodate more feces, and the sealing design is more compact and convenient, which is convenient for safe sealing and replacement after the feces are filled, the bottom plate part usually has strong adhesion and good sealing, can be closely attached to the skin around the stoma, effectively preventing feces leakage, and can maintain stability even when the patient is active; the urinary pouch is mainly used for collecting urine, such as Figure 2 The structural design focuses more on preventing urine leakage and odor emission, usually uses an anti-reflux device to prevent urine backflow from causing infection to the stoma and urinary system, and the pouch body material generally has good flexibility and stretch resistance to adapt to the flow and storage of urine, and the bottom plate part in contact with the skin usually uses materials with strong hydrophilicity and good air permeability to ensure comfort and skin health during long-term wearing, and reduce skin irritation and allergic reactions caused by urine.

[0040] The stomal pouch 100 generally comprises a pouch body 1 and an exhaust structure 2, the pouch body 1 is formed with a cavity for storing excrement, and the pouch body 1 is provided with an adhesive member, the inside of the adhesive member is provided with a communication hole communicating with the cavity, when the stomal pouch 100 is used, the communication hole is sleeved on the outer circumferential side of the stoma, the adhesive member is attached to the skin of the patient, and the exhaust structure 2 comprises a ring body 21 connected to the pouch body 1 and a blocking body 22 movable in the ring body 21, the exhaust structure 2 and the adhesive member are on the opposite sides of the pouch body 1, so as to ensure that the gas released by the ring body 21 will not be directly released to the skin of the patient to cause pollution.

[0041] The tail part of the pouch body 1 is usually provided with an opening that can be closed or opened, which is convenient for pouring the excrement in the pouch body 1, and after pouring the excrement in the pouch body 1, the opening can be used to clean the inside of the pouch body 1, and when cleaning, clean water, physiological saline or appropriate cleaning agent is added to the inside of the pouch body 1 to ensure that the excrement in the pouch body 1 can be cleaned and deodorized at the same time.

[0042] When exhaust is needed, the blocking body 22 is moved from the first position to the second position, in the first position, the blocking body 22 and the ring body 21 are sealed, the cavity is in a closed state, and after moving to the second position, an exhaust passage is formed between the blocking body 22 and the ring body 21, one end of the passage communicates with the cavity, and the other end communicates with the outside, so that the gas accumulated in the cavity can be exhausted, and when the exhaust is completed, the blocking body 22 can be moved back to the first position to restore the sealing state and prevent the odor of excrement from being emitted and leakage.

[0043] The exhaust structure 2 can timely exhaust the gas in the cavity of the ostomy bag 100, avoid the expansion and even rupture of the ostomy bag 100 due to the accumulation of gas, and ensure the safety and stability of the use of the ostomy bag 100, and through the switching of the blocking body 22 between the first position and the second position, the exhaust time can be flexibly controlled, the sealing performance can be maintained in the non-exhaust state, the leakage of excrement can be prevented, the influence on the living environment of the user can be reduced, and the user can operate the blocking body 22 relatively conveniently and easily.

[0044] The exhaust structure 2 can also be provided in other structure types, for example, a one-way valve is arranged on the bag body 1, when the pressure in the cavity reaches a certain degree, the gas can push open the one-way valve to be exhausted, and the outside air and excrement cannot enter through the one-way valve, and this scheme has the advantages of relatively simple structure and possibly lower cost, but there can be the case that the exhaust is not complete, or a breathable film area is arranged on the bag body 1 and is used for exhausting gas, and an movable sealing cover is additionally provided. The sealing cover is opened when exhaust is needed, and is closed after the exhaust is completed to prevent odor emission, and the breathable film can continuously and slowly exhaust, but the sealing performance of the sealing cover needs to be further optimized, and the movable sealing cover can not be very convenient to operate frequently.

[0045] Therefore, in the technical scheme of the utility model, the exhaust structure 2 comprises a ring body 21 connected to the bag body 1 and a blocking body 22 capable of being arranged in the ring body 21 and moving relatively to the ring body 21, the blocking body 22 has a first position and a second position in the moving stroke of the blocking body 22, in the first position, the blocking body 22 and the ring body 21 are sealed, and in the second position, an exhaust passage is formed between the blocking body 22 and the ring body 21, one end of the exhaust passage can communicate with the cavity, and the other end communicates with the outside, the gas in the bag body 1 is released to the outside through the ring body 21, and the excrement in the bag body 1 is prevented from leaking out through the ring body 21 by the movable blocking body 22.

[0046] Please see Figures 3 to 6, the plugging body 22 needs to be limited to avoid the plugging body 22 from being separated from the ring mouth body 21 at will when the plugging body 22 is in the first position. Common limiting structures include clamping structures. The clamping structure needs to be additionally provided with a structure for facilitating the release of the clamping structure while clamping the plugging body 22 in the ring mouth body 21, which increases the number of parts and the production cost. In the embodiment, the plugging body 22 is screw-mounted in the ring mouth body 21, a threaded gap is formed between the plugging body 22 and the ring mouth body 21, and the plugging body 22 extends outward to form an annular extension; corresponding to the first position of the plugging body 22, the annular extension is sealed against the end of the ring mouth body 21, so that the plugging body 22 and the ring mouth body 21 are sealingly matched; corresponding to the second position of the plugging body 22, the annular extension is spaced from the end of the ring mouth body 21 to form a spacing gap between the annular extension and the end of the ring mouth body 21, and the exhaust passage includes the threaded gap and the spacing gap.

[0047] The plugging body 22 is screw-mounted in the ring mouth body 21, and when the plugging body 22 is in the first position, the annular extension extending outward is sealed against the end of the ring mouth body 21. This close abutment state forms an effective seal between the plugging body 22 and the ring mouth body 21, preventing the gas and excrement in the cavity from leaking outward, and ensuring the sealing of the ostomy bag 100 in the non-exhaust state. When exhaust is needed, the plugging body 22 is moved to the second position relative to the ring mouth body 21 through rotation or other operations. At this time, the annular extension is spaced from the end of the ring mouth body 21 to form a spacing gap between the annular extension and the end of the ring mouth body 21. At the same time, since there is a threaded gap between the plugging body 22 and the ring mouth body 21, the exhaust passage is formed by the threaded gap and the spacing gap. In this way, the gas in the cavity can be smoothly discharged to the outside through the exhaust passage.

[0048] When the ostomy bag 100 is used normally and does not need to be vented, the closure body 22 is in the first position, and the annular extension is tightly sealed against the end of the ring body 21, so that an effective seal is formed between the closure body 22 and the ring body 21, and the cavity is in a closed state, thereby preventing the emission of odor and leakage of excrement. When a certain amount of gas accumulates in the ostomy bag 100 and needs to be vented, the user operates the closure body 22 by rotating or other means to move it to the second position relative to the ring body 21. In this process, the annular extension gradually separates from the end of the ring body 21, forming a gap between them. At the same time, since the closure body 22 and the ring body 21 are threadedly connected, there is a thread gap between them. At this time, the venting channel is formed by the thread gap and the gap, and the gas accumulated in the cavity can be vented to the outside through this venting channel, which is connected to the cavity at one end and to the outside at the other end. When the venting is completed, the user operates the closure body 22 again to return it to the first position, and the annular extension reseals against the end of the ring body 21 to restore the sealing state.

[0049] When cleaning, the ring body 21 can also be used for cleaning. The closure body 22 is completely rotated out of the ring body 21, thereby opening the ring body 21, and then physiological saline, water or suitable cleaning agent is added through the ring body 21 into the bag body 1 to clean the excrement inside the bag body 1. When cleaning the tail of the bag body 1, the pipe needs to be inserted into the bag body 1, which causes the pipe to be contaminated. When cleaning through the ring body 21, the ring body 21 can be placed on the top of the bag body 1, and the sewage is discharged through the bottom opening while being flushed, which is more efficient.

[0050] Further, a sealing assembly 25 is provided between the annular extension and the ring body 21, and the sealing assembly 25 includes a sealing block 251 and a sealing groove 252. One of the sealing block 251 and the sealing groove 252 is provided on the side of the annular extension facing the ring body 21, and the other is provided on the side of the ring body 21 facing the annular extension.

[0051] The cooperation of the sealing block 251 and the sealing groove 252 further optimizes the sealing effect between the annular extension and the ring mouth body 21. When the blocking body 22 is in the first position, the sealing assembly 25 can fill the possible small gap, compared with the previous sealing mode relying on the abutting of the annular extension and the end of the ring mouth body 21, can more effectively prevent the emission of fecal odor and the leakage of feces, provide a cleaner and more comfortable use experience for the user, and the arrangement of the sealing assembly 25 can reduce the direct friction and wear between the annular extension and the ring mouth body 21. During the frequent switching of the blocking body 22 between the first position and the second position, the sealing block 251 and the sealing groove 252 bear part of the friction loss, thereby prolonging the service life of the exhaust structure 2 as a whole and reducing the risk of reduced sealing performance due to frequent use.

[0052] The gas released outward through the exhaust passage is limited and the release rate is slow, although the condition of the excrement and dirt outside is avoided, but it is easy to cause a large amount of gas to accumulate inside the pocket body 1, causing the pressure inside the pocket body 1 to be too large, which may cause the ostomy bag 100 to expand and explode, so it is necessary to release a large amount of gas to release pressure when the internal pressure of the ostomy bag 100 rises to a certain degree. Specifically, in the embodiment of the utility model, the blocking body 22 is provided with a through hole, one end of the through hole can communicate with the cavity, and the other end communicates with the outside. The through hole includes a first communication part and a second communication part which are in communication with each other. The diameter of the first communication part is smaller than the diameter of the second communication part, and the second communication part is located on the side of the first communication part facing the pocket body 1.

[0053] A through hole is arranged on the blocking body 22 to communicate the cavity with the outside, so that the gas in the pocket body 1 can escape to the outside from the through hole in addition to the exhaust passage, and the through hole is divided into two parts in communication with each other, which are the first communication part and the second communication part. The second communication part communicates with the cavity, and the first communication part communicates with the outside. Only one of the two communication parts needs to be closed to close the through hole. The diameter of the first communication part is smaller than the diameter of the second communication part, so that the through hole is arranged in a stepped manner. A stepped plug can be arranged in the through hole, and the movement distance of the plug is limited, so that the plug cannot completely separate from the through hole. Therefore, the plug forms a gap between the inner wall of the through hole after moving a certain distance, thereby discharging the gas in the pocket body 1. At the same time, due to the blocking of the step, it is difficult for the excrement to smoothly pass through the gap and leak to the outside of the pocket body 1.

[0054] Specifically, in the embodiment of the utility model, the exhaust structure 2 further includes pressure relief assembly 23, the pressure relief assembly 23 includes connecting column 234, plugging plate 233, movable plate 231 and elastic element 232, the connecting column 234 is movably arranged in the through hole, and the cross-sectional area of the connecting column 234 is gradually tapered along the axial direction, the plugging plate 233 is arranged at one end of the connecting column 234 and is axially movable along the connecting column 234, the movable plate 231 is detachably arranged at the other end of the connecting column 234 and is axially movable along the connecting column 234, one end of the elastic element 232 is mounted to the movable plate 231, and the other end is mounted to the cavity wall of the second communication part, and the elastic element 232 is used to drive the movable plate 231 away from the plugging piece.

[0055] The connecting column 234 penetrates the through hole, and the two ends of the connecting column 234 are respectively provided with the plugging plate 233 and the movable plate 231. During the movement of the connecting column 234 in the through hole, the plugging plate 233 and the movable plate 231 are driven to move towards or away from the plugging block, so as to close the first communication part or the second communication part, thereby closing the through hole. At the same time, the elastic element 232 is matched, and the elastic element 232 enables the movable plate 231 to automatically return to the initial position after movement through the elastic potential energy. That is, when the movable plate 231 is not under stress, it is located in the cavity, the plugging plate 233 is in contact with the plugging body 22, and the first communication part is closed. When the gas in the pocket body 1 accumulates to a certain degree and the pressure rises, the movable plate 231 is pushed outward, the elastic element 232 is compressed, and the plugging plate 233 is driven by the connecting column 234 to move away from the plugging block, thereby releasing the lock of the first communication part, so that the through hole can communicate the cavity with the outside, thereby discharging the accumulated gas in the pocket body 1 to the outside. After the elastic element 232 is contracted to a certain degree, the movable plate 231 will be attached to the plugging body 22, thereby closing the second communication part, preventing the excrement in the pocket body 1 from leaking out. When the gas in the pocket body 1 and the inside needs to be completely released, the plugging body 22 can be rotated out of the ring mouth body 21, thereby completely releasing the lock of the ring mouth body 21, so that the gas can be discharged to the outside.

[0056] The cross-sectional area of the connecting column 234 is gradually tapered along the axial direction, that is, the cross section of the connecting column 234 along the axial direction is trapezoidal, so that there is a larger gap between the outer peripheral side of the connecting column 234 and the inner cavity wall of the through hole, and the inclined surface is more easily guided to flow to the outside, so that the air in the pocket body 1 can flow to the outside quickly, that is, the shorter side of the connecting column 234 is arranged to face the inside of the pocket body 1, and the longer side is arranged to face the outside, so that the gas in the pocket body 1 is more easily discharged to the outside, and the gas in the outside is easily communicated to the inside of the pocket body 1 through the through hole.

[0057] The cooperation of the connecting column 234, the blocking plate 233, the movable plate 231 and the elastic piece 232 can make the gas in the pocket body 1 overflow outside when the gas pressure in the pocket body 1 is too high, so as to avoid the problem that the gas in the pocket body 1 is too much to cause the explosion of the patient. The movable plate 231 is detachably arranged, so that the connecting column 234 can be taken out for replacement or cleaning.

[0058] Further, the cross-sectional area of the first communication part is gradually reduced along the axial direction of the connecting column 234, and the area of the side of the movable plate 231 facing the blocking plate 233 is greater than the area of the side of the first communication part away from the blocking plate 233.

[0059] The first communication part is shaped to be similar to the connecting column 234, so that the connecting column 234 can be completely fitted with the inner cavity wall of the partial through hole to block the through hole, and the through hole is double-sealed by the blocking block, so as to prevent the substances in the pocket body 1 from leaking out.

[0060] The gas discharged from the pocket body 1 is mainly generated by excrement, so the smell is very unpleasant. The amount of gas discharged through the exhaust passage is small, and it is easy to disperse and not easy to be smelled. The amount of gas discharged through the pressure relief assembly 23 is large in a short time, so it will form a temporary accumulation, which will cause the patient and medical staff to smell the odor and feel uncomfortable. Therefore, the gas discharged by the pressure relief assembly 23 needs to be filtered. Specifically, in the embodiment of the utility model, the blocking body 22 is provided with a filter groove on the side facing the blocking plate 233, the filter groove is in communication with the first communication part, and the filter groove is provided with a filter piece 24, and the filter piece 24 is used to filter the gas released in the cavity.

[0061] By arranging a filter piece 24 in the exhaust gas flow path of the pressure relief assembly 23, the gas needs to be filtered by the filter piece 24 when flowing, so as to purify the smell of the gas and reduce the damage of the gas discharged by the pocket body 1 to the patient or medical staff. The movable plate 231 is detachably arranged, so that the connecting column 234 can be taken out for replacement or cleaning, and the filter groove can be easily opened to take out the filter piece 24 for replacement, so as to avoid the filter piece 24 losing the filtering effect after long-term use.

[0062] The patient is often in a lying state when resting, and the patient is easy to resist the movable plate 231 in the lying state, thereby pushing the movable plate 231, so that the through hole is opened, and therefore it is necessary to limit the movement of the movable plate 231, and specifically, in the embodiment of the utility model, the blocking plate 233 is provided with at least one limiting portion 2331 on the outer circumferential side, and the blocking body 22 is provided with a limiting groove for the movement connection of the limiting portion 2331, so as to limit the movement of the blocking plate 233 when the limiting portion 2331 slides into the limiting groove.

[0063] Before the patient lies down, the blocking plate 233 is pressed, so that the limiting portion 2331 on the blocking plate 233 enters the gap on the blocking body 22, and the blocking plate 233 is rotated, so that the limiting portion 2331 enters the limiting groove, and after the limiting portion 2331 enters the limiting groove, the blocking plate 22 can only rotate and move, cannot move axially along the connecting column 234, and cannot move to the circumferential side, thereby avoiding that the movable plate 231 is pushed away to open the through hole after being pressed, and at the same time, only the exhaust passage can be opened by rotating the blocking body 22 to perform exhaust work.

[0064] In order to avoid that the blocking body 22 cannot be found after being rotated out of the ring mouth body 21, the blocking body 22 and the ring mouth body 21 are connected to a certain extent, so that the blocking body 22 is still connected with the ring mouth body 21 through the connecting structure after being rotated out of the inner cavity of the ring mouth body 21, and specifically, in the embodiment of the utility model, the outer side of the connecting column 234 is sleeved with a movable ring 4, and a flexible connecting piece 3 is arranged between the movable ring 4 and the blocking body 22.

[0065] The movable ring 4 and the blocking body 22 are connected together through the flexible connecting piece 3, so that the movement distance of the blocking body 22 can be limited through the movable ring 4 sleeved on the outer side of the ring mouth body 21, and the subsequent use of the blocking body 22 is facilitated, and at the same time, the movable ring 4 can be sleeved on the ring mouth body 21 to rotate, so that the blocking body 22 can be rotated into or out of the ring mouth body 21.

[0066] The movable plate 231 is arranged in the pocket body 1 cavity and is easy to touch the inner cavity wall of the pocket body 1, and the outer wall corresponding to the inner cavity wall of the pocket body 1 is limited and cannot move when contacting the skin, so that the movable plate 231 can be pushed to move in the opposite direction, so that the through hole is accidentally opened, and therefore it is necessary to avoid that the movable plate 231 contacts the inner cavity wall of the pocket body 1, and specifically, in the embodiment of the utility model, the ring mouth body 21 is provided with a supporting portion 211 extending from the movable ring 4 towards the cavity, the supporting portion 211 covers the movable plate 231, so as to limit the movable plate 231 from contacting the skin of the patient or the pocket body 1, and a plurality of air inlet holes are formed on the outer circumferential side of the connecting portion, and the air inlet holes are used to assist the gas to enter the supporting portion 211.

[0067] The ring mouth body 21 extends a part into the cavity of the pocket body 1 to form a supporting part 211, so that the movable plate 231 is contained in the supporting part 211, so that the ring mouth body 21 is in contact with the inner cavity wall of the pocket body 1 instead of the movable plate 231, avoiding the problem that the movable plate 231 is accidentally pressed to open the through hole by external force to cause excrement to leak out. At the same time, the position of the ring mouth body 21 is also limited, and needs to avoid the communication hole on the adhesive member to avoid touching the stoma position of the patient to cause injury to the patient. At the same time, a plurality of through holes are formed on the side of the supporting part 211, so that the gas in the pocket body 1 can enter the second communication part, avoiding the problem that the cavity wall of the supporting part 211 and the movable plate 231 form a shielding, so that the gas is difficult to enter the second communication part in a large amount and then discharged to the outside through the first communication part.

[0068] The above is only the preferred embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structural transformation or direct / indirect application in other related technical fields within the concept of the present application, using the content of the present application specification and drawings, is included in the patent protection range of the present application.
