Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an ostomy bag device with an intestinal fluid filtering and recovery function. Background Art

[0002] Stomas are generally used for rectal and bladder diseases (such as rectal cancer, bladder cancer, intestinal obstruction, etc.). In order to save the patient's life, the doctor will surgically remove the diseased part. For example, rectal cancer will remove the rectum and anal canal, and bladder cancer will remove the bladder, and then open an opening on the left or right side of the patient's abdomen. Feces or urine are involuntarily discharged from the body through the stoma. After being discharged from the hospital, such patients will need to stick a bag on the stoma to hold the discharged things. The bag stuck is the stoma bag.

[0003] When a stoma is set on a patient, in addition to feces, secretions that are beneficial to nutrient absorption will also enter the stoma bag with the feces for storage. At this time, intestinal fluid and feces in the stoma bag are stored together in the bag. When a large amount of intestinal fluid in the human body is lost, the ability of the intestine to decompose and absorb nutrients will decrease, which can easily cause poor nutrient absorption in patients and easy dryness of the intestine. Therefore, it is necessary to return the intestinal fluid to the intestine to maintain the lubrication of the intestine and the ability of the intestine to decompose nutrients.

[0004] The existing method is to remove the ostomy bag, filter the intestinal fluid in the ostomy bag through a breathable object such as gauze, and then return it to the patient's intestine. This method is very troublesome to filter, and will emit a lot of odor due to mixing with feces.

[0005] To this end, the present application proposes an ostomy bag device with intestinal fluid filtering and recovery function, which is convenient for filtering, recovering and isolating odor of intestinal fluid. Summary of the invention

[0014] Preferably, the filter portion is a soft filter mesh, and the filter portion is arranged below the male quick connector.

[0015] Preferably, the filter part is tiltedly arranged inside the bag body, a side of the filter part away from the male quick connector is higher than the other side, and a lower side of the filter part is level with an inner bottom of the male quick connector.

[0016] Preferably, the sealing plug comprises a plug body, the axis of the plug body is provided with a liquid outlet channel extending into the plug body, the bottom of the plug body is provided with a plug groove concentric with the liquid outlet channel, and the diameter of the plug groove is larger than the inner diameter of the liquid outlet channel;

[0017] A one-way valve is arranged inside the plug body to cover the mouth of the liquid outlet channel to seal the liquid outlet channel.

[0018] Preferably, the one-way valve comprises a sealing plate, which is arranged inside the plug body and covers the top of the liquid outlet channel, a vertical sliding rod is arranged at the edge of the bottom of the plug body and penetrates into the inside of the plug slot, a limiting block is arranged at the lower end of the sliding rod, and an elastic member is sleeved on the outer surface of the sliding rod;

[0019] The upper end of the elastic member contacts the inner top of the plug-in slot, and the lower end of the elastic member contacts the top of the limit block. When the limit block is pressed, the elastic member can be compressed to leave a gap between the bottom of the sealing plate and the top of the liquid outlet channel.

[0020] Preferably, the secondary storage bag comprises a bag body 2, and a quick connector nut is provided on the top of the side surface of the bag body 2, and the quick connector nut is adapted to the quick connector male.

[0021] Preferably, the bottom of the bag body 2 does not exceed the bottom of the sealing plug, and the bag body 2 is a soft transparent bag body.

[0022] Preferably, a filter grate is provided inside the quick connector nut, the filter grate is trumpet-shaped, one end of the filter grate facing the bag body 2 is closed, the other end of the filter grate is open, and the wall surface of the filter grate is provided with filter holes.

[0023] Preferably, an anti-slip ring is provided on the inner wall of the quick connector nut, and the inner diameter of the anti-slip ring is larger than the closing opening of the filter grate bucket and smaller than the opening of the filter grate bucket.

[0024] As described above, the ostomy bag device with intestinal fluid filtering and recovery function of the present invention has the following beneficial effects:

[0025] 1. The present invention arranges a secondary storage bag on the side of the main storage bag. When the main storage bag collects intestinal fluid and excrement, the main storage bag filters the excrement through the internal filter part, so that the intestinal fluid is located at the inner bottom of the main storage bag, and the excrement enters the interior of the secondary storage bag for collection, thereby achieving the effect of filtering and separation. When the intestinal fluid is recovered, it is connected to the bottom of the main storage bag through a catheter, thereby avoiding the diffusion of irritating odor.

[0026] At the same time, when cleaning excrement, the secondary storage bag can be directly separated to dump the excrement, avoiding the need to disassemble the main storage bag, which may cause the stoma to be easily contaminated, or opening the bottom of the main storage bag to discharge the excrement, which may cause the excrement to splash onto the body or clothes.

[0027] 2. The present invention filters excrement by obliquely arranging a filter part inside bag body one. When the excrement contacts the filter part, it will roll toward the male quick connector under the action of gravity and enter the interior of bag body two, thereby effectively preventing the excrement from accumulating on the filter part and causing blockage of the filter part.

[0028] At the same time, when excrement enters the bag body 1, the filter part will reduce the travel distance, reduce the impact force, and avoid the impact force of the excrement causing the bag body 1 to suddenly fall and pull the connection between the bag body 1 and the stoma, thereby improving comfort.

[0029] 3. The present invention seals the mouth of the liquid outlet pipe by forming a sealing plug through a plug body, a liquid outlet channel, a connecting groove and a one-way valve. When recovering intestinal fluid, the catheter is inserted into the connecting groove and connected to the outer surface of the liquid outlet channel, and the catheter is made to upwardly contact the one-way valve to realize the circulation of liquid, thereby avoiding the effect of opening the sealing plug and then connecting the catheter on the liquid outlet pipe, which is prone to leakage.

[0030] At the same time, the pressure in the bag will increase due to intestinal gas. This pressure will exert pressure on the intestinal fluid when recovering the intestinal fluid, thereby increasing the speed of the intestinal fluid passing through the one-way valve, achieving the effect of improving the recovery speed.

[0031] 4. The present invention sets a filter grate inside the quick connector nut. When the intestinal fluid is filtered through the filter part, part of the intestinal fluid will enter the interior of the bag body two along with the excrement. At this time, the intestinal fluid can be refluxed to the interior of the bag body one to be filtered again by tilting and bending the bag body two, while the set filter grate blocks the excrement in the refluxed intestinal fluid, thereby avoiding or reducing the pressure caused by the excrement entering the interior of the bag body one on the filtering performance of the filter part.

[0032] At the same time, an anti-drop ring is provided on the inner wall of the quick connector nut to limit the filter grate bucket, thereby effectively preventing the filter grate bucket from falling into the interior of bag body two, and the end of the filter grate bucket facing bag body one is blocked by the quick connector male, achieving the effect of preventing the filter grate bucket from deviating.

[0033] Moreover, the detachable filtering grate bucket can make it more convenient to clean the excrement in the bag body 2, thereby avoiding the obstruction caused by the filtering grate bucket and resulting in insufficient dumping of the excrement.

[0034] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0050] like Figure 1 As shown, the present invention provides an ostomy bag device with intestinal fluid filtering and recovery function, comprising a main storage bag 1 and a secondary storage bag 2. The main storage bag 1 can be attached to the surface of a human stoma and can be used to collect and filter solid and liquid objects flowing out of the stoma. The secondary storage bag 2 is connected to the main storage bag 1 and can be used to collect solid objects.

[0051] The upper part of the side of the secondary storage bag 2 is detachably mounted on the middle part of the side of the main storage bag 1. When cleaning the excrement in the secondary storage bag 2, the secondary storage bag 2 can be removed for cleaning to avoid the need to remove the main storage bag 1 from the human body, which causes inconvenience in use or easy infection of the stoma. The bottom of the main storage bag 1 is provided with a socket for an external catheter. When recovering intestinal fluid, the intestinal fluid in the main storage bag 1 can be drained by connecting the infusion pole or catheter to the bottom of the main storage bag 1, and the excrement is collected inside the secondary storage bag 2.

[0052] like Figure 2-Figure 3 As shown, in some embodiments, the main storage bag 1 of the present invention includes a bag body 101, which is the main body for storing excrement and intestinal fluid, and its main structure is the same as that of an existing ostomy bag. A stoma patch 102 is provided on the upper part of one side of the bag body 101, and the stoma patch 102 can be pasted and covered on the stoma. The stoma patch 102 can be cut according to the diameter of the stoma. A liquid outlet pipe 103 is provided at the bottom of the bag body 101, which is used to discharge the intestinal fluid stored in the bag body 101, and can be directly connected to the catheter. A sealing plug 106 is provided at the end of the liquid outlet pipe 103 to seal the liquid outlet pipe 103 to prevent the intestinal fluid from leaking through the liquid outlet pipe 103 under normal circumstances. When recovering the intestinal fluid, the sealing plug 106 can be removed from the liquid outlet pipe 103. A male quick connector 104 is provided in the middle of the bag body 101 away from the stoma patch 102 . The male quick connector 104 is used to connect to the secondary storage bag 2 and serve as a circulation channel for excrement, so that the excrement can enter the interior of the secondary storage bag 2 .

[0053] The bag body 101 is provided with a filter 105 inside, which divides the inside of the bag body 101 into two spaces, one above and one below, and can be used to filter intestinal fluid. When intestinal fluid and excrement enter the bag body 101 through the stoma, the intestinal fluid and excrement will first fall on the filter 105, and the larger particles of excrement will be blocked by the filter 105, while the liquid intestinal fluid will pass through the filter 105 and enter the inner bottom of the bag body 101 to be collected, thereby achieving the separation of intestinal fluid and excrement. And when the patient is in a standing state, the excrement will fall into the auxiliary storage bag 2 after being buffered by the filter 105. Reduce the impact force of excrement on the bag body 101, and avoid the impact force pulling the bag body 101, which causes the bag body 101 to fall off from the stoma or pull the wound. When the intestinal fluid is filtered through the filter 105, the intestinal gas discharged from the stoma will pressurize the inside of the bag 101, so that the intestinal fluid can pass through the filter 105 faster and enter the inner bottom of the bag 101. When the filter 105 is blocked, pressure is applied to the bottom of the bag 101 to make the intestinal fluid flow back to impact the filter holes of the filter 105 to clear the blockage.

[0054] During use, the mouth of the quick connector male 104 can be exposed by disassembling the secondary storage bag 2, so that the quick connector male 104 and the stoma patch 102 are connected. When performing operations such as drug injection and stoma disinfection, there is no need to disassemble the bag body 101, which improves the convenience of use and reduces the risk of stoma infection.

[0055] like Figure 3As shown, in some embodiments, the filter part 105 of the present invention is a soft filter net. When the bag body 101 is not in use, the filter part 105 can be folded along with the bag body 101, thereby improving the convenience of storage. The filter part 105 is arranged below the quick connector 104 to improve the filtering effect on the intestinal fluid, and to prevent the intestinal fluid from immediately entering the interior of the secondary storage bag 2 under the action of gravity when it falls on the filter part 105.

[0056] like Figure 3 As shown, in some embodiments, the filter part 105 of the present invention is tilted inside the bag body 101, the side of the filter part 105 away from the quick connector 104 is higher than the other side, and the lower side of the filter part 105 is level with the inner bottom of the quick connector 104. Through the above technical solution, the tilted filter part 105 can make the excrement gather better in the direction of the quick connector 104 under the action of gravity, avoiding the excrement from being spread on the top of the filter part 105 and causing the filter part 105 to be blocked. At the same time, the intestinal fluid will also increase the flow distance due to the tilt of the filter part 105.

[0057] like Figure 7-Figure 9 As shown, in some embodiments, the sealing plug 106 of the present invention includes a plug body 1061, the axis of the plug body 1061 is provided with a liquid outlet channel 1062 extending to the inside of the plug body 1061, and the bottom of the plug body 1061 is provided with a plug groove 1063 concentric with the liquid outlet channel 1062, and the diameter of the plug groove 1063 is larger than the inner diameter of the liquid outlet channel 1062. The above structure can replace the liquid outlet tube 103 when in use, and the catheter can be inserted into the plug groove 1063 and sleeved on the outer surface of the liquid outlet channel 1062 to achieve communication with the inside of the bag body 101. There is no need to disassemble the sealing plug 106 when in use, which improves the convenience of use.

[0058] A one-way valve 1064 is provided inside the plug body 1061 to cover the mouth of the liquid outlet channel 1062 and seal the liquid outlet channel 1062. This is used to prevent intestinal fluid from leaking through the liquid outlet channel 1062 in normal times. After the catheter is connected, the end of the catheter will collide with the one-way valve 1064, thereby releasing the seal of the one-way valve 1064 and connecting the catheter to the bag body 101, thereby achieving the extraction and recovery of intestinal fluid.

[0059] like Figure 9-10As shown, in some embodiments, the one-way valve 1064 of the present invention includes a sealing plate 10641, which is arranged inside the plug body 1061 and covers the top of the liquid outlet channel 1062. Thus, the mouth of the liquid outlet channel 1062 is sealed by the sealing plate 10641 to prevent intestinal fluid leakage. A vertical sliding rod 10642 is provided at the edge of the bottom of the plug body 1061 to penetrate into the interior of the plug slot 1063, a limiting block 10643 is provided at the lower end of the sliding rod 10642, and an elastic member 10644 is sleeved on the outer surface of the sliding rod 10642. Among them, the limiting block 10643 is used to limit the rising height of the sliding rod 10642, support the elastic member 10644 and prevent the elastic member 10644 from detaching.

[0060] The upper end of the elastic member 10644 contacts the inner top of the plug-in slot 1063, and the lower end of the elastic member 10644 contacts the top of the stopper 10643. When the elastic member 10644 is not subjected to force, the elastic member 10644 will exert force downward on the stopper 10643, so that the sealing plate 10641 can be stably fitted to the mouth of the liquid outlet channel 1062 for sealing. At the same time, the sealing effect of the sealing plate 10641 can be better in combination with the intestinal gas pressure inside the bag body 101. After the catheter is inserted, the stopper 10643 will compress the elastic member 10644, so that a gap is left between the bottom of the sealing plate 10641 and the top of the liquid outlet channel 1062, thereby realizing the circulation of intestinal fluid. At the same time, when there is too much intestinal gas inside the bag body 101 and the bag body 101 is over-expanded, the bag body 101 can be slightly folded upward to keep the intestinal fluid away from the liquid outlet tube 103, and then the limit block 10643 can be pushed by an object to achieve the exhaust effect.

[0061] like Figure 1 and Figure 4 As shown, in some embodiments, the secondary storage bag 2 of the present invention includes a bag body 201 for storing excrement and part of intestinal fluid. A quick connector nut 202 is provided at the top of the side of the bag body 201, and the quick connector nut 202 is adapted to the quick connector male 104. It is used to cooperate with the quick connector male 104 to connect the bag body 201 to the side of the bag body 1 101. When the excrement is blocked by the filter part 105, it will enter the interior of the bag body 201 through the quick connector nut 202 and be collected.

[0062] like Figure 1As shown, in some embodiments, the bottom of the second bag body 201 of the present invention does not exceed the bottom of the sealing plug 106. It is prevented that the second bag body 201 is attached to the sealing plug 106 and the liquid outlet tube 103, thereby causing the second bag body 201 to wear or reciprocately touch the sealing plug 106, thereby causing the sealing plug 106 to open and leak. The second bag body 201 is a soft transparent bag body, which is convenient for users to observe the remaining capacity in the second bag body 201 and clean the excrement in the second bag body 201 in time. Or the second bag body 201 is bent, and the intestinal fluid in the second bag body 201 is refluxed to the inside of the first bag body 101 for re-filtration, thereby increasing the amount of intestinal fluid collected.

[0063] like Figure 2 , Figure 4-Figure 6 As shown, in some embodiments, a filter grate 203 is provided inside the quick connector nut 202 of the present invention. When the intestinal fluid is filtered through the filter part 105, part of the intestinal fluid will enter the inside of the bag body 201 along with the excreta. In order to recover this part of the intestinal fluid, it is necessary to tip the bag body 201 to allow the intestinal fluid to flow back to the position of the filter part 105 for re-filtration. At this time, the excreta will flow back with the intestinal fluid, which can easily cause the filter part 105 to be blocked. For this reason, a filter grate 203 is provided to block the excreta. The filter grate 203 is in the shape of a trumpet, and the end of the filter grate 203 facing the bag body 201 is closed, and the other end of the filter grate 203 is open, and the wall of the filter grate 203 is provided with filter holes. This design is to leave a gap between the inner side of the filter grate 203 and the edge of the quick connector nut 202 when the intestinal fluid is refluxed, so as to block a large amount of excrement and reduce the excrement from entering the bag body 101 and causing large-scale blockage of the filter part 105. The intestinal fluid will enter the interior of the bag body 101 through the filter and the center of the filter grate 203.

[0064] like Figure 6 As shown, in some embodiments, the inner wall of the quick connector female 202 of the present invention is provided with an anti-slip ring 204, and the inner diameter of the anti-slip ring 204 is larger than the closing end of the filter grate 203 and smaller than the opening end of the filter grate 203. The purpose of providing the anti-slip ring 204 is to limit the position of the filter grate 203 to prevent the filter grate 203 from falling into the interior of the bag body 201, while the other end of the filter grate 203 will be blocked by the end of the quick connector male 104. Therefore, the filter grate 203 will not fall into the interior of the bag body 101.

[0065] The specific use process of the present invention is as follows:

[0066] Determine the sealing performance of the sealing plug 106 to the liquid outlet pipe 103;

[0067] The stoma is cleaned and disinfected, and then the stoma patch 102 is cut so that the inner diameter of the stoma patch 102 is adapted to the stoma, and the stoma patch 102 is pasted on the stoma;

[0068] Insert the filter grate 203 into the inside of the quick connector nut 202, so that the filter grate 203 and the anti-slip ring 204 conflict with each other, and install the bag body 201 on the side of the bag body 1 101 through the quick connector male 104 and the quick connector nut 202;

[0069] When there is too much intestinal fluid in the bag body 201, the bag body 201 is tilted to allow the intestinal fluid in the bag body 201 to flow back to the bag body 101 and be filtered again by the filter unit 105;

[0070] When cleaning the excrement, remove the bag body 201 from the quick connector nut 202, and temporarily seal the quick connector male 104 to prevent subsequent excrement leakage. At the same time, take out the filter grate 203 from the quick connector nut 202 to clean the excrement in the bag body 201;

[0071] When collecting intestinal fluid, the catheter is directly inserted from the bottom of the sealing plug 106, and the end of the catheter is pressed against the limit block 10643 to create a gap between the sealing plate 10641 and the liquid outlet channel 1062, so that the intestinal fluid can pass into the catheter, and under the pressure of the intestinal gas inside the bag body 101, the collection efficiency of the intestinal fluid can be effectively improved;

[0072] When releasing intestinal gas, the bottom of the bag body 101 is bent to keep the intestinal fluid away from the mouth of the liquid outlet tube 103, and then an object is used to apply pressure to the limit block 10643 to achieve exhaust;

[0073] After the entire device has been used multiple times, the device can be discarded to avoid stoma infection caused by contamination of the device.

[0074] In summary, the ostomy bag device with intestinal fluid filtering and recovery function of the present invention is configured by arranging a secondary storage bag 2 on the side of the main storage bag 1. When the main storage bag 1 collects intestinal fluid and excrement, the main storage bag 1 filters the excrement through the internal filter part 105, so that the intestinal fluid is located at the inner bottom of the main storage bag 1, and the excrement enters the interior of the secondary storage bag 2 for collection, thereby achieving the effect of filtering and separation. When the intestinal fluid is recovered, it is connected to the bottom of the main storage bag 1 through a catheter, thereby avoiding the diffusion of irritating odors.

[0075] At the same time, when cleaning excrement, the secondary storage bag 2 can be directly separated to dump the excrement, avoiding the need to disassemble the main storage bag 1, which may cause the stoma to be easily contaminated, or opening the bottom of the main storage bag 1 to discharge the excrement, which may cause the excrement to easily splash onto the body or clothes.

[0076] The present invention filters excrement by obliquely setting the filter part 105 inside the bag body 101. When the excrement contacts the filter part 105, it will roll toward the quick connector 104 under the action of gravity and enter the interior of the bag body 201, thereby effectively preventing the excrement from accumulating on the filter part 105 and causing the filter part 105 to be blocked.

[0077] At the same time, when excrement enters the bag body 101, the filter 105 reduces the travel distance and the impact force, thereby preventing the impact force of the excrement from causing the bag body 101 to suddenly fall and pull the connection between the bag body 101 and the stoma, thereby improving comfort.

[0078] The present invention seals the mouth of the liquid outlet pipe 103 by forming a sealing plug 106 through a plug body 1061, a liquid outlet channel 1062, a connecting groove 1063 and a one-way valve 1064. When recovering intestinal fluid, the catheter is inserted into the connecting groove 1063 and connected to the outer surface of the liquid outlet channel 1062, and the catheter is upwardly pressed against the one-way valve 1064 to realize the circulation of liquid, thereby avoiding the effect of opening the sealing plug 106 and then connecting the catheter to the liquid outlet pipe 103, which is prone to leakage.

[0079] At the same time, the pressure in the bag body 101 will increase due to intestinal gas. This pressure will exert pressure on the intestinal fluid when recovering the intestinal fluid, thereby increasing the speed of the intestinal fluid passing through the one-way valve 1064, achieving the effect of improving the recovery speed.

[0080] The present invention sets a filter grate 203 inside the quick connector nut 202. When the intestinal fluid is filtered through the filter unit 105, part of the intestinal fluid will enter the interior of the bag body 201 along with the excreta. At this time, the inclined bending of the bag body 201 can make the intestinal fluid flow back to the interior of the bag body 101 to be filtered again, and the set filter grate 203 blocks the excreta in the refluxed intestinal fluid, thereby avoiding or reducing the pressure on the filtering performance of the filter unit 105 caused by the excreta entering the interior of the bag body 101.

[0081] At the same time, an anti-slip ring 204 is set on the inner wall of the quick connector nut 202 to limit the filter grate 203, thereby effectively preventing the filter grate 203 from falling into the interior of the bag body 201, and the end of the filter grate 203 facing the bag body 101 is blocked by the quick connector male 104, thereby achieving the effect of preventing the filter grate 203 from deflecting.

[0082] The detachable filtering grate 203 can make it more convenient to clean the excrement in the bag body 201, and avoid the filtering grate 203 causing obstruction and resulting in insufficient dumping of excrement.

[0083] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0084] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
