Description

Technical Field

[0001] The invention belongs to the field of stoma chassis, and in particular relates to a special stoma chassis for wading with an indication function and a stoma system. Background Art

[0002] Patients need to use an ostomy bag to store human excreta after some ostomy surgeries. The ostomy bag is connected to the stoma site through a ostomy base plate, which is bonded to the skin. Excreta enters the ostomy bag through the central hole of the ostomy base plate.

[0003] Stoma patients also have water needs, such as rehabilitation hydrotherapy, swimming, and hot spring soaking. The existing stoma base is simply bonded to the skin and has poor sealing. Water can easily penetrate between the stoma base and the skin, but it cannot be directly perceived by stoma patients. The stoma base is not replaced in time, resulting in long-term retention of moisture. The skin under the stoma base turns white after being soaked for a long time, and ulcers or even infections occur, especially in swimming pool water containing chlorine, which aggravates irritation.

[0004] In addition, human excrement contains gas, which enters the ostomy bag through the stoma base. After entering the water, the ostomy bag will float and generate a certain buoyancy, which will pull the human body's stoma position through the stoma base, causing pain to the human body.

When the nut is rotated to the outer side of the spring piece, the protrusion enters the annular groove.

[0012] In the aforementioned special ostomy system for water wading, the front end of the elastic piece is provided with a limit baffle extending radially outward.

[0013] In the aforementioned water-specific ostomy system, the negative pressure box is provided with a pipe joint extending out of the ostomy bag, and the air inlet end of the mini air pump is provided with a hose extending out of the sealing bag and connected to the pipe joint, and the side wall of the hose has an opening with an air hole located in the sealing bag.

[0015] In the aforementioned special ostomy system for water-related ostomy, the negative pressure box is filled with filter particles.

[0016] Compared with the prior art, the stoma base plate of the present invention has a three-layer structure. The adhesive layer is used to fix the stoma base plate to the human skin. By selecting a flexible reinforcement layer, the stoma base plate has a certain strength and can better adapt to the curved surface of the human skin, so that the bonding strength between the stoma base plate and the skin is higher, it is not easy to fall off, it is not easy to produce gaps, and it is not easy to get water in. Even under the action of limb movement, a certain gap is produced between the edge of the stoma base plate and the skin. The sealing ring near the outer edge of the stoma base plate expands with rainwater, which can form a secondary seal to prevent water from continuing to penetrate inward. It has good sealing performance and is suitable for underwater use. By setting an observation window on the reinforcement layer and setting a color indicator in the observation window, when water enters the stoma base tray, the color indicator changes color to give the user a prompt so that the user can deal with it in time to avoid long-term immersion near the stoma. Even if the user does not notice the color indicator within a certain period of time, the water entering the stoma base tray will move inward under the capillary action of the water guide hole and enter the water-absorbing gasket. The inside of the stoma base tray can still be kept dry for a considerable period of time, leaving sufficient time for the user to replace the stoma base tray.

[0017] The stoma system of the present invention features a convenient connection between the ostomy bag and the stoma base, making it easy to replace the bag. Furthermore, the connection between the bag and the stoma base is reliable, preventing the bag from accidentally falling off during use and ensuring that water does not enter the window through the insertion tube, ensuring safe use. A detachable sealing bag is provided on one side of the ostomy bag, and an electrically driven mini air pump is installed in the sealing bag. The sealing air pump simultaneously evacuates the bag and the sealing bag, preventing the bag from floating in water and causing damage to the wound, reducing pain and further improving safety.

[0018] In summary, the present invention has the advantages of being suitable for use underwater and safe to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and examples, but they are not intended to limit the present invention.

[0027] Example 1: A special ostomy chassis with an indication function for wading, such as Figure 1 As shown, it includes a first insert tube 1, one end of the first insert tube 1 extends radially outward to form a flange 2, and the first insert tube 1 and the flange 2 are formed on a single part by injection molding.

[0028] An adhesive layer 3 is provided on the bottom surface of flange 2. Adhesive layer 3 is made of a skin-friendly, moisturizing acrylic or rubber-based pressure-sensitive adhesive. Adhesive layer 3 extends radially outward beyond flange 2. A reinforcing layer 4 and a waterproof layer 5 are provided on the outer side of adhesive layer 3. Reinforcing layer 4 is cut from 0.5-0.8 mm thick PE board, ensuring both strength and flexibility. Waterproof layer 5 is a transparent plastic film. Reinforcing layer 4 has an outer diameter of approximately 10 cm.

[0029] The adhesive layer 3 is provided with a plurality of elongated, spiral-shaped water-conducting holes 6. These holes are preferably through-holes, with their depth determined by the thickness of the adhesive layer 3. These holes are evenly distributed circumferentially around the axis of the adhesive layer 3, with a width of 0.1-0.2 mm and a depth of 0.2-0.3 mm. The elongated structure of the holes does not substantially reduce the bonding area or strength of the adhesive layer 3. The reinforcing layer 4 is provided with an observation window 7 corresponding to the location of the water-conducting holes 6. Within the observation window 7 is a color indicator that changes color when exposed to water. The color indicator can be placed on a medium, such as a test paper. All observation windows 7 must be covered by the waterproof layer 5.

[0030] The inner circle of the reinforcing layer 4 is fixed to the top surface of the flange 2. A water-absorbing gasket 8 is provided between the flange 2 and the adhesive layer 3. The material of the water-absorbing gasket 8 can be a water-absorbing resin pressed into a sheet. The inner diameter of the water-absorbing gasket 8 should be larger than the inner diameter of the first inserting tube 1. The inner end of the water guide hole 6 extends between the inner and outer circles of the water-absorbing gasket 8.

[0031] The adhesive layer 3 is provided with an annular groove 9, the bottom surface of the groove 9 can extend to the reinforcing layer 4, the groove 9 is close to the outer edge of the adhesive layer 3, and a sealing ring 12 that expands when exposed to water is provided in the groove 9. The outer end of the water guide hole 6 extends to the groove 9. The material of the sealing ring 12 can be a water-absorbing resin pressed into a sheet.

[0032] The stoma tray works as follows: the stoma is aligned with the first cannula 1, and excreta from the stoma is discharged through the first cannula 1. The stoma tray adheres to the skin via the adhesive layer 3. Once immersed in water, the water barrier 5 prevents water from moving axially into the stoma tray, while the adhesive layer 3 acts as a seal, preventing water from entering radially into the stoma tray.

[0033] When exercising in water, due to the repeated bending and wrinkling of the skin, the outer edge of the adhesive layer 3 may be partially separated from the skin, and water enters along the gap and contacts the sealing ring 12 in the groove 9. The sealing ring 12 swells when it encounters water, fills the gap, and prevents water from continuously entering, thus prolonging the drying time inside the stoma chassis. When the water entry time is too long, the stoma chassis is further separated from the skin, and water may break through the interception of the sealing ring 12 and continue to penetrate inward. Since the water guide hole 6 is elongated, a capillary effect will be produced, and water will move inward along the water guide hole 6 and be absorbed in the water-absorbing gasket 8, preventing water from spreading along the adhesive layer 3 plane, and reducing the water contact area of ​​the stoma chassis covering the skin. The spiral water guide hole 6 has a large interception range for water, and water moves in the spiral water guide hole 6, and there is also a certain spiral centripetal effect, which increases the drainage speed and has a certain effect on reducing the water content inside the stoma chassis.

[0034] When water breaks through the sealing ring 12 and continues to move inward, it will contact the color indicator in the observation window 7, and the color indicator will change color, giving a signal to remind the user to drain the water and replace it with a new stoma base plate.

[0035] Example 2: A special ostomy system for water-related wading, comprising a waterproof ostomy bag 13 and the ostomy base plate of Example 1.

[0036] A negative pressure box 10 is provided on the inner side of the upper end of the ostomy bag 13, and a second cannula 11 is provided on the negative pressure box 10. One end of the second cannula 11 is plugged into the first cannula 1, and the other end of the second cannula 11 is bent and extends downward to extend out of the negative pressure box 10 and remain in the ostomy bag 13. A plurality of filter holes 14 are provided on the second cannula 11, all of which are located in the negative pressure box 10. A water-blocking and breathable membrane 15 covering the filter holes 14 is provided on the outer side of the second cannula 11. A sealing bag 16 (plastic bag) connected to the negative pressure box 10 is provided on the outer side of the ostomy bag 13. A mini air pump 17 and a battery pack 18 connected to the mini air pump 17 are provided in the sealing bag 16. The air inlet end of the mini air pump 17 is connected to the negative pressure box 10, and the air outlet pipe of the mini air pump 17 is connected to a one-way valve 19. The one-way valve 19 is located on the sealing bag 16.

[0037] The mini air pump 17 uses 3V, 0.2A specifications, and the battery pack 18 is composed of two 1.5V 18650 batteries connected in series. The mini air pump 17 can work continuously for 6-8 hours. The battery pack 18 is connected to the mini air pump 17 through a button switch 32.

[0038] The second cannula 11 is located inside the first cannula 1. An O-ring 20 is provided on the outside of the front end of the second cannula 11 to mate with the first cannula 1. An annular groove 21 is provided on the outside of the rear end of the second cannula 11. A nut 22 is provided on the outside of the first cannula 1. The end of the first cannula 1 is provided with multiple outwardly extending spring clips 23. The outer sides of the spring clips 23 are provided with external threads 24 that mate with the nut 22. The inner sides of the spring clips 23 are provided with protrusions 25 that mate with the annular groove 21. A radially outward-extending stopper 26 is provided on the front end of the spring clips 23. The first cannula 1, spring clips 23, protrusions 25, and stopper 26 are injection-molded onto the same part. When the nut 22 rotates to the outside of the spring clips 23 and contacts the stopper 26, the protrusions 25 enter the annular groove 21, releasing the pressure.

[0039] The negative pressure box 10 is provided with a pipe joint 27 extending out of the ostomy bag 13, and the air inlet end of the mini air pump 17 is provided with a hose 28 extending out of the sealing bag 16 and connected to the pipe joint 27. The side wall of the hose 28 is opened with an air hole 29 located in the sealing bag 16.

[0040] The sealing bag 16 is connected to the ostomy bag 13 by Velcro fasteners. The sealing bag 16 is connected to the lower part of the ostomy bag 13. A counterweight 30 is provided in the sealing bag 16. The counterweight 30 ensures that the ostomy bag 13 sinks in water. The rotational connection between the ostomy bag 13 and the stoma base also ensures that the ostomy bag 13 is in an upright position in water and does not fall over and cause the contents inside to flow back.

[0041] The negative pressure box 10 is filled with filter particles 31. The filter particles 31 can be activated carbon to absorb the odor of stoma exhaust.

[0042] To use the stoma system: After squeezing and emptying the stoma bag 13, insert the second cannula 11 into the first cannula 1. The O-ring provides a seal and dampens relative rotation between the second and first cannula 11. Tighten the nut 22 against the stopper 26. The spring 23 rotates inward, allowing the protrusion 25 to enter the annular groove 21, creating a rigid axial stop and preventing the second cannula 11 from axially dislodging from the first cannula 1.

[0043] Push button switch 32 electrically connects the battery pack 18 to the mini air pump 17. The mini air pump 17 extracts air from the sealed bag 16 through the air holes 29 and releases it through the one-way valve 19, causing the bag 16 to deflate and reduce its buoyancy. The mini air pump 17 creates a negative pressure inside the negative pressure box 10 via the hose 28. Solid and liquid waste discharged from the stoma enters the ostomy bag 13 through the second cannula 11. Exhaust gas from the stoma passes through the filter holes 14 and the water-blocking, breathable membrane 15 and enters the negative pressure box 10. After being filtered and absorbing odor molecules, it is driven by the mini air pump 17 and discharged through the one-way valve 19. To prevent backflow of the fluid inside the ostomy bag 13 under negative pressure, the suction pressure of the mini air pump 17 should be relatively low. A diaphragm-type one-way valve (common structure) can also be installed at the discharge end of the second cannula 11 to prevent backflow of the fluid inside the bag.

[0044] When replacing the ostomy bag, separate the hose 28 from the pipe joint 27, separate the sealing bag 16 from the ostomy bag, rotate the nut 22 to open the spring 23, and pull out the second cannula 11. The mini air pump 17 and the battery pack 18 in the sealing bag 16 form an assembly and can be reused.
