Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a post-ostomy filtering intestinal fluid ostomy bag. Background Technology

[0002] In clinical treatment after enterostomy, the fecal matter produced in the early stages of enterostomy (such as after neonatal necrotizing enterocolitis) is mostly thin and liquid, requiring intestinal fluid reinfusion to maintain the infant's nutritional balance. However, as the enterostomy progresses to the later stages (such as the intestinal repair period or the chronic enterostomy stage), the amount of intestinal fluid secretion decreases and is often mixed with incompletely digested food residues or inflammatory fibrin clots, forming clump-like fecal matter containing a high concentration of nutrients. At this stage, although the digestive and absorptive functions of the intestines improve somewhat, some degree of impairment may still exist. Incompletely digested food residues remain in the feces due to insufficient secretion of digestive enzymes or uncoordinated intestinal peristalsis. The appearance of inflammatory fibrin clots may be related to the inflammatory response of the intestines. During inflammation, fibrinogen and other substances seep out and form clots in the intestines, mixing with the fecal matter.

[0003] In our earlier application for an ostomy bag, a filter layer was created by arranging sealed indentations at intervals to form a filter channel. This design not only reduces material and manufacturing costs but also lowers the resistance caused by the complexity of the filter components. Furthermore, prior art CN207768796U describes an ostomy bag with a filter device for intestinal fluid reinfusion, mainly composed of an existing ostomy bag, a double-lumen balloon catheter, and an intestinal fluid filtration and reinfusion device. It achieves the collection, filtration, and reinfusion of intestinal fluid through a one-way valve, an elastic rubber balloon, an intestinal fluid filtration membrane, and an intestinal fluid reinfusion tube, reducing the amount of disposable ostomy bags and artificial nutrition solutions used, and maintaining the stability of the patient's internal environment. However, the aforementioned earlier application and prior art do not differentiate between the stages of intestinal fluid reinfusion requirements: early, thin intestinal fluid can be directly reinfused, while later, clump-forming fecal fluid requires physical sieving to retain effective intestinal fluid components (such as short-chain fatty acids and electrolytes) while separating solid residues. Summary of the Invention

[0004] This invention proposes a gradient filtration scheme that simplifies filtration stages and enhances the mechanical screening of agglomerated fecal residue, specifically for the later stages of sewage treatment.

[0005] The technical solution of this invention is implemented as follows:

[0006] A post-ostomy filter-type intestinal fluid ostomy bag includes an ostomy bag with an ostomy hole on one side and a return tube at the bottom; the ostomy bag is divided into an intestinal fluid treatment area and an intestinal fluid return area by a row of filter layers; wherein the filter layers are composed of multiple sealing indentations arranged at intervals, and a filter channel is left between adjacent sealing indentations, through which fecal matter is filtered out.

[0007] The ostomy bag is equipped with a secondary treatment bag corresponding to the top of the filter layer and connected to the intestinal fluid treatment zone. The secondary treatment bag is divided into a guide zone and a fecal zone. A guide port and an exhaust port for venting excess gas are respectively provided below the guide zone and the fecal zone. Some fecal fluid enters the fecal zone through the guide port of the guide zone.

[0008] The secondary treatment bag is connected to the fecal area above the exhaust port via a recovery pipe. The other end of the return pipe is connected to the intestinal fluid treatment area. The recovery pipe is also equipped with a filter element and a check valve. The guide port and exhaust port are closed, and the fecal area of ​​the secondary treatment bag is squeezed, so that excess intestinal fluid is recovered to the intestinal fluid treatment area through the filter element and check valve, and then filtered again by the filter layer before entering the intestinal fluid return area.

[0009] Furthermore, the staggered distribution between adjacent sealing indentations increases the filter pore size.

[0010] Furthermore, the intestinal fluid reflux zone is provided with a scale mark B for observing the volume of intestinal fluid.

[0011] Furthermore, a reflux guide tube is provided above the ostomy bag, and the reflux guide tube has a detachable sealing cap, wherein the reflux tube can pass through the reflux guide tube and be led out through the ostomy hole.

[0012] Furthermore, the return tube is provided with a scale mark A near its end for observing the insertion depth.

[0013] Furthermore, it also includes a chassis connected to the stoma, with the side of the chassis away from the stoma connected to the stoma opening.

[0014] Furthermore, the flow inlet and exhaust outlet are staggered to facilitate the sedimentation of fecal matter in the transition of fecal liquid.

[0015] Furthermore, the secondary treatment bag is equipped with switches at the corresponding flow inlet and exhaust outlet on its exterior.

[0016] Furthermore, an exhaust pipe is provided at the bottom of the secondary treatment bag below the exhaust port.

[0017] The beneficial effects of the technical solution provided in this application are as follows:

[0018] This post-ostomy filtering intestinal fluid bag, through the addition of a recovery tube, internal filter element, and check valve, combined with the partitioned design of the secondary treatment bag, can effectively recover excess intestinal fluid retained in the secondary treatment bag. Specifically: after closing the inlet and outlet, the fecal matter compression area can return the intestinal fluid to the intestinal fluid treatment area after secondary filtration. There, it undergoes fine separation through the sealing indentations and filtration channels of the filter layer, ultimately allowing the intestinal fluid to enter the return zone for reuse. This process significantly improves the return efficiency of intestinal fluid, reduces nutrient loss, and avoids blockage problems caused by impurity accumulation, ensuring the continuity and stability of intestinal fluid return.

Detailed Implementation

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

[0026] Reference Figure 1-4A post-ostomy filtering intestinal fluid ostomy bag includes an ostomy bag 10 with an ostomy port 11 on one side and a return tube 12 at the bottom; the ostomy bag 10 is divided into an intestinal fluid processing area 13 and an intestinal fluid return area 14 by a row of filter layers 20; wherein the filter layer 20 is composed of multiple sealing indentations 21 arranged at intervals, and a filter channel 22 is left between adjacent sealing indentations 21, through which fecal matter is filtered out.

[0027] The stoma port 11, located on one side of the ostomy bag 10, is used to drain intestinal fluid from the neonatal's proximal enterostomy to the intestinal fluid treatment zone 13 inside the ostomy bag 10. A filter layer 20, disposed on the ostomy bag 10, consists of multiple spaced sealing indentations 21 forming filter channels 22. These channels allow liquids and useful substances in the intestinal fluid to pass through while intercepting larger particles and impurities. Nutrients can flow smoothly from the intestinal fluid treatment zone 13 to the intestinal fluid return zone 14 and are then returned to the neonatal's distal enterostomy via the return tube 12. The intestinal fluid treatment zone 13, located above the filter layer 20, collects the intestinal fluid entering through the stoma port 11, where it is filtered. The intestinal fluid return zone 14, located below the filter layer 20, collects the filtered intestinal fluid and returns it to the neonatal through the return tube 12.

[0028] Intestinal fluid from the neonatal proximal enterostomy is received through stoma 11 and flows into intestinal fluid treatment zone 13. In this zone, the intestinal fluid is filtered through filtration channels 22 of filter layer 20 to remove large particles and impurities. The filtered intestinal fluid flows into intestinal fluid return zone 14 and is guided back to the neonatal distal enterostomy through return tube 12, enabling the reuse of intestinal fluid and absorption of nutrients. Throughout the process, the design of filter layer 20 effectively balances filtration efficiency and resistance to intestinal fluid flow, ensuring the continuity and efficiency of intestinal fluid return while reducing the cost and maintenance difficulty caused by the complexity of the filter components.

[0029] In this technical solution, the function and structure of the secondary treatment bag 30 are further optimized. The secondary treatment bag 30 is connected to the intestinal fluid treatment zone 13 of the ostomy bag 10, and its interior is designed with two areas: a guide zone 31 and a fecal matter zone 32. A guide port 33 and an exhaust port 34 are respectively provided below the guide zone 31 and the fecal matter zone 32. After the discharged fluid is filtered through the filter channel 22, the remaining fecal fluid enters the fecal matter zone 32 through the guide port 33. In addition, the secondary treatment bag 30 is also equipped with a recovery pipe 35, one end of which is connected to the fecal matter zone 32, and the other end is connected to the intestinal fluid treatment zone 13. The recovery pipe 35 contains a filter element 36 and a check valve 37. By closing the guide port 33 and the exhaust port 34 and squeezing the fecal matter zone 32, excess intestinal fluid can be recovered through the filter element 36 and the check valve 37 to the intestinal fluid treatment zone 13, and then enter the intestinal fluid return zone 14 through the fine filtration of the filter layer 20.

[0030] By closing the inlet 33 and outlet 34 and squeezing the fecal area 32 of the secondary treatment bag 30, excess intestinal fluid that was originally retained in the fecal area 32 is recycled. The filter element 36 in the recovery pipe 35 performs secondary filtration of the intestinal fluid, removing any remaining impurities, while the check valve 37 ensures that the intestinal fluid flows in only one direction, preventing backflow. The pre-filtered intestinal fluid re-enters the intestinal fluid treatment zone 13, where it undergoes further fine separation through the sealing indentation 21 and filter channel 22 of the filter layer 20. This process not only improves the efficiency of intestinal fluid return and reduces nutrient loss, but also avoids blockage caused by impurity accumulation, ensuring the continuity and stability of intestinal fluid reinfusion. With this design, the post-ostomy filtering intestinal fluid ostomy bag of this invention can more efficiently manage intestinal fluid in the post-ostomy environment, providing better care for newborns.

[0031] In some embodiments, adjacent sealing indentations 21 are staggered vertically. The special design of the filter layer 20 lies in the fact that its sealing indentations 21 are not simply arranged side-by-side or in a straight line, but rather staggered vertically. This staggered arrangement means that each row of sealing indentations 21 is offset from the adjacent row above or below by a certain distance, forming a stepped or checkerboard-like layout. This staggered design of the sealing indentations 21 increases the surface area of ​​the filter channel 22, thereby improving filtration efficiency. When intestinal fluid flows into the intestinal fluid treatment zone 13, the staggered sealing indentations 21 can more effectively disperse the intestinal fluid, reducing liquid accumulation on the filter layer 20 and preventing a decrease in filtration efficiency or blockage of the filter channel 22 due to local overload. Simultaneously, this design also helps reduce the resistance of the filter layer 20 to the flow of intestinal fluid, because the staggered arrangement reduces dead zones and turbulence during the intestinal fluid flow process, allowing the intestinal fluid to pass more smoothly through the filter channel 22 and enter the intestinal fluid return zone 14.

[0032] In some embodiments, the intestinal fluid reflux zone 14 is provided with a scale marker B60 for observing the volume of intestinal fluid. After the intestinal fluid enters the reflux zone 14 through the filtration layer, the scale marker B60 indicates the current fluid level status through color segmentation (such as a yellow warning zone and a green safety zone). The scale marker B60 provides medical staff with real-time volume monitoring data of the intestinal fluid reflux zone 14 through preset volume scale lines and time axis markings, solving the recording deviation problem caused by subjective estimation in traditional ostomy bags; its linearly distributed transparent observation window combined with gradient density scale (such as a fixed fluid level line corresponding to each hour) allows medical staff to directly read the cumulative reflux volume and record the operation time, facilitating dynamic evaluation of intestinal fluid recovery efficiency and adjustment of the balloon compression frequency.

[0033] In some embodiments, a reflux guide port 50 is provided above the ostomy bag 10. The reflux guide port 50 has a detachable sealing cap, through which the reflux tube 12 can pass and exit through the stoma hole 11. The reflux guide port 50, with its detachable sealing cap design, provides a dual-mode adaptation function for dual-lumen stoma environments: in a dual-lumen scenario where the proximal and distal ostomies are in the same location, removing the sealing cap allows the reflux tube 12 to pass through the guide port 50 and be inserted into the distal stoma, enabling cross-lumen return of intestinal fluid; in an ectopic dual-lumen scenario, the sealing cap maintains the airtightness of the ostomy bag 10, and the reflux tube 12 is independently inserted into the distal stoma, avoiding the risk of foreign body friction or cross-contamination of lumens due to the presence of the guide port 50, thus accommodating the clinical needs of different anatomical structures. Specifically: When the proximal and distal stomas are in the same position, after removing the sealing cap, the return tube 12 is inserted into the distal stoma through the guide channel of the guide tube port 50, and the intestinal fluid enters the return tube 12 through the internal flow channel of the stoma bag 10 to achieve cross-cavity return; when the stoma is displaced, the sealing cap closes the guide tube port 50, and the return tube 12 independently passes through the stoma hole 11 and is directly inserted into the distal stoma.

[0034] In some embodiments, the reflux tube 50 is provided with a scale mark A40 near its end for observing the insertion depth. When inserting into the distal stoma, medical staff control the advancement distance of the reflux tube 50 using a preset threshold of scale mark A40 (by setting different color marks as different depth warnings) to ensure that the catheter tip is located in the effective drainage area of ​​the intestinal lumen.

[0035] In some embodiments, a base plate 70 connected to the stoma is also included, with the side of the base plate 70 away from the stoma connected to the stoma opening 11. The base plate 70 is a component directly connected to the neonatal stoma, and its function is to fix and seal the ostomy bag 10, ensuring that intestinal fluid can flow smoothly from the stoma into the ostomy bag 10. The base plate 70 is designed with a specific structure that allows it to fit tightly against the neonatal skin, while the side away from the stoma is connected to the stoma opening 11. The working principle of the base plate 70 is based on its sealed connection with the stoma; it serves as the base of the ostomy bag 10, providing a stable starting point for the collection and reinfusion of intestinal fluid. One side of the base plate 70 is connected to the neonatal stoma, and its adaptive design ensures a tight fit with the skin around the stoma, preventing leakage of intestinal fluid. The other side of the base plate 70 is connected to the stoma opening 11, forming a channel for intestinal fluid from the stoma to the ostomy bag 10. When the neonatal produces intestinal fluid, the intestinal fluid first flows into the base plate 70, and then enters the intestinal fluid processing area 13 of the ostomy bag 10 through the stoma opening 11. The chassis 70 design may also include mechanisms for easy installation and replacement, as well as ensuring comfort and breathability of the parts in contact with a newborn's skin to avoid skin problems that may result from prolonged wear.

[0036] In some embodiments, the guide port 33 and the vent port 34 are staggered, i.e., not vertically aligned, to create a gradient transition in the flow path of the fecal liquid. The guide port 33 is located at the top or side of the fecal area 32, guiding the fecal liquid into the area where it gradually settles due to gravity. The vent port 34 is located at the bottom of the fecal area 32, extending the flow path of the fecal liquid in the guide area 31 through the staggered design. This promotes the natural sedimentation of solid fecal matter in the fecal area 32, reduces the risk of pipe blockage caused by liquid-solid mixing, and ensures clear stratification of the fecal liquid. The staggered distribution design alters the fluid dynamics, making it easier for heavier solid particles to settle at the bottom of the fecal area 32, while lighter liquid components are more easily forced into the recovery pipe 35.

[0037] In some embodiments, switches 38 are respectively installed on the outside of the secondary treatment bag 30 at the corresponding inlet 33 and outlet 34, allowing independent control of the opening and closing states of the two outlets. The switch 38 at the inlet 33 controls the flow of fecal fluid from the guide zone 31 to the fecal matter zone 32; the switch 38 at the outlet 34 controls the timing of the release of excess gas from the fecal matter zone 32. This design, by precisely controlling the liquid flow path and velocity, prevents intestinal fluid backflow or fecal backflow, ensuring the effectiveness of the zoning function within the secondary treatment bag. The external placement of the switches 38 allows caregivers to operate without direct contact with the inside of the secondary treatment bag, reducing the risk of contamination. Manual adjustment of the opening and closing degree of the switches 38 allows for flexible responses to different fecal fluid flow requirements and rapid sealing of the system during intestinal fluid recovery, providing pressure conditions for subsequent compression of the fecal matter zone 32. Furthermore, the sealing design of the switches 38 prevents liquid leakage, maintaining the overall hygiene and safety of the device. The switch 38 controls the opening and closing of the guide port 33 and the exhaust port 34 through external mechanical control. During the fecal liquid guide stage, the guide port is kept open and the exhaust port is closed to ensure that the fecal liquid is preferentially deposited in the fecal matter area 32. During the intestinal fluid recovery stage, the two switches are closed and the intestinal fluid is squeezed into the recovery pipe 35 by squeezing the fecal matter area 32.

[0038] In some embodiments, an exhaust pipe 39 is added below the exhaust port 34. The exhaust pipe 39 can be used to discharge excess gas from the ostomy bag 10 and the secondary treatment bag 30, preventing air from swelling and affecting the entry of fecal fluid. In use, the guide port 33 is closed but the exhaust port 34 is not closed. The secondary treatment bag 30 is flipped upward so that the exhaust pipe 39 faces upward. At this time, the fecal area 32 of the secondary treatment bag 30 is squeezed, so that excess intestinal fluid is recovered to the intestinal fluid treatment area 13 through the filter element 36 and the check valve 37, and then filtered again by the filter layer 20 before entering the intestinal fluid return area 14. During this process, excess gas in the secondary treatment bag 30 can be discharged. After the operation is completed, the exhaust port 34 is closed to prevent fecal matter from being squeezed out.

[0039] In some embodiments, by designing the bottoms of the guide zone 31 and the fecal matter zone 32 as inclined or curved, gravity is used to guide the natural flow direction of liquid and solid particles. The inclined bottom of the guide zone 31 promotes rapid flow of fecal liquid to the guide port 33, reducing liquid retention; the curved or inclined bottom of the fecal matter zone 32, through hydrodynamic characteristics, allows heavier solid fecal matter to slide along the curved or inclined surface towards the vicinity of the exhaust port 34 and concentrate for deposition, while the lighter liquid components remain in a flowing state. This design optimizes solid-liquid separation efficiency and reduces the risk of blockage caused by fecal matter accumulation.

[0040] An important component, the reflux peristaltic pump, is added to the ostomy bag containing filtered intestinal fluid after the stoma procedure. The reflux peristaltic pump is a pump designed to provide a stable flow of power and works in conjunction with the reflux tubing 50. The reflux tubing 50 passes through the interior of the peristaltic pump, which provides the necessary pressure for the flow of intestinal fluid through its pumping mechanism.

[0041] In a post-ostomy filter-type enterocolpos, the peristaltic pump provides a continuous and gentle force for the return of intestinal fluid from the ostomy bag 10 to the newborn's body. After the intestinal fluid passes through the filter layer 20 and enters the intestinal fluid return zone 14, the peristaltic pump begins operation. Through its internal rollers or rotors, the pump compresses the intestinal fluid within the return tube 50. This compression allows the intestinal fluid to flow through the return tube 50 at a continuous and uniform rate, ultimately reaching the distal enterostomy. The peristaltic pump operates similarly to intestinal peristalsis, mimicking natural intestinal movement, thereby reducing irritation to the intestinal wall and preventing the destruction of nutrients in the intestinal fluid.

[0042] Furthermore, the reflux peristaltic pump can adjust its operating speed and pressure to adapt to the different physiological needs of newborns and changes in the viscosity of intestinal fluid. By precisely controlling the reflux rate and volume of intestinal fluid, the recovery of intestinal function and nutrient absorption in newborns can be better promoted.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
