Description

Technical Field

[0001] The present invention relates to the technical field of stoma care, and more particularly to a stoma care component and a method of using the same. Background Art

[0002] After intestinal surgery, the stoma formed during the operation is a potential route for bacterial invasion. If the postoperative care is improper, such as failure to clean and disinfect the stoma in time, or the patient's immunity is low, it may lead to stoma infection. After the stoma infection, bacteria will multiply in large numbers at the stoma and release toxins. These toxins will have a destructive effect on the surrounding tissues, causing tissue cell death, and then causing necrosis of the surrounding tissues. If the infection further spreads to the intestine, it will cause damage to the intestinal wall. After the intestinal wall is damaged, the intestinal contents flow out through the damaged part to form an intestinal fistula. In order to ensure the normal healing of the stoma wound, it is necessary to install a stoma care component to guide the outflow of intestinal contents and prevent the intestinal contents from flowing into the stoma wound through the intestinal fistula and affecting the healing of the stoma wound. Before installing the stoma care component, the stoma wound needs to be cleaned to remove dirt, bacteria and other microorganisms in the stoma wound area. Since the stoma is concave inward, cleaning the stoma wound is very inconvenient.

[0003] The existing stoma care components have a single function, and because the stoma is recessed inwards, the installation of the existing stoma care components is also very inconvenient. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects in the prior art and provide a stoma care component capable of cleaning a stoma wound surface and a method of using the same.

[0005] To achieve the above object, the technical solution of the present invention is to provide a stoma care component, comprising: A cleaning unit, comprising a buffer cotton, an infusion tube and a suction tube, wherein the buffer cotton completely covers the stoma wound surface, the buffer cotton is provided with a through hole corresponding to the intestinal fistula, and a flushing liquid inlet part and a flushing liquid outlet part are respectively provided in the buffer cotton on both sides of the through hole, and one end of the infusion tube and the suction tube are respectively inserted into the flushing liquid inlet part and the flushing liquid outlet part; A blocking and diversion unit is connected to the cleaning unit and is used to isolate the intestinal fistula and the stoma wound surface and guide the flow of intestinal contents; The ostomy bag is connected to the blocking unit and is used for collecting intestinal contents.

[0006] By using a stoma care component according to the present invention, the buffer cotton can be attached to the stoma wound surface to fill the depression at the stoma, jointly forming a good installation base surface with the skin, facilitating the installation of the ostomy bag. After the ostomy bag is installed, it is not easy to fall off. By injecting physiological saline into the buffer cotton through an infusion tube and absorbing the physiological saline in the buffer cotton through a liquid suction tube, the stoma wound surface can be continuously cleaned, solving the problem of inconvenient cleaning of the stoma wound surface.

[0007] Preferably, the part of the infusion tube extending into the buffer cotton is axially provided with a plurality of liquid outlet holes distributed at intervals, and the center line directions of the plurality of liquid outlet holes all face the axis direction of the liquid suction tube. The part of the liquid suction tube extending into the buffer cotton is axially provided with a plurality of liquid inlet holes distributed at intervals, and the center line directions of the plurality of liquid inlet holes all face the axis direction of the infusion tube. The ends of the infusion tube and the liquid suction tube extending into the buffer cotton are both sealed. With such a design, the negative pressure formed in the liquid suction tube is transmitted to the buffer cotton through the liquid inlet holes, and the physiological saline flowing into the buffer cotton from the liquid outlet holes will quickly diffuse towards the liquid suction tube direction, which is beneficial to improving the cleaning efficiency of the stoma wound surface.

[0008] Preferably, the ratio of the aperture of the liquid outlet hole to the inner diameter of the infusion tube is 0.25 - 0.5, the ratio of the center distance between two adjacent liquid outlet holes to the inner diameter of the infusion tube is 1 - 4, the ratio of the aperture of the liquid inlet hole to the inner diameter of the liquid suction tube is 0.3 - 0.7, and the ratio of the center distance between two adjacent liquid inlet holes to the inner diameter of the liquid suction tube is 1.2 - 5. With such a design, the physiological saline flowing out from the liquid outlet holes can be more evenly diffused into the buffer cotton, thereby cleaning the stoma wound surface more comprehensively, which is beneficial to improving the cleaning effect of the stoma wound surface.

[0009] Preferably, a transparent film is attached to the outside of the buffer cotton, and the transparent film is attached to the skin around the buffer cotton. The transparent film is provided with an opening corresponding to the through hole. The transparent film, the plugging and guiding unit and the skin form a sealed space, and the buffer cotton is located in the sealed space. With such a design, the transparent film can fix the buffer cotton, prevent the buffer cotton from falling off, and block the contact between external bacteria and pollutants and the stoma wound surface.

[0010] Preferably, the plugging and guiding unit includes a guiding ring, a deformable membrane and a leak-proof ring. The deformable membrane is of an annular structure. The outer ring of the guiding ring is connected to the inner ring of the deformable membrane. The guiding ring communicates with the stoma bag. The inner ring of the leak-proof ring is connected to the outer ring of the deformable membrane. Both the deformable membrane and the leak-proof ring are made of elastic materials. The deformable membrane is provided with an inner cavity. The guiding ring is provided with an injection channel communicating with the inner cavity. A seal is provided at the injection port of the injection channel. The gap between the leak-proof ring and the stoma wound surface is filled with leak-proof paste. With such a design, the plugging and guiding unit can adapt to through holes of different sizes and shapes, greatly improving the adaptability of the plugging and guiding unit.

[0011] Preferably, the seal is a rubber seal block. With such a design, it is beneficial to improve the convenience of the seal for plugging the injection channel.

[0012] Preferably, hydrogel powder is stored in the inner cavity of the deformable membrane. With such a design, the hydrogel powder can be swollen and solidified by injecting clean water into the inner cavity, thereby limiting the position of the guiding ring, which is beneficial to the discharge of intestinal contents.

[0013] Preferably, the height of the leak-proof ring is greater than the thickness of the buffer cotton. A notch is provided on the part of the leak-proof ring protruding above the buffer cotton. The part of the leak-proof ring protruding above the buffer cotton fits with the transparent film. The gap between the part of the leak-proof ring protruding above the buffer cotton and the transparent film is filled with leak-proof paste. With such a design, it is beneficial to improve the sealing performance of the sealed space.

[0014] Preferably, the stoma bag includes a chassis and a bag body. The chassis is detachably connected to the bag body. The chassis is attached to the transparent film. The chassis is provided with a sleeve hole matching with the guiding ring. The chassis is sleeved on the outer ring of the guiding ring. With such a design, it is beneficial to the rapid installation of the chassis and the replacement of the bag body.

[0015] A method for using a stoma care assembly includes the following steps: S1. Measure and record the sizes of the stoma wound surface and the intestinal fistula opening, as well as the position distribution of the intestinal fistula opening on the stoma wound surface; S2. Make the buffer cotton; S3. Make the infusion tube and the liquid suction tube, and insert them into the buffer cotton; S4. Place the buffer cotton on the stoma wound surface, attach the transparent film to fix the buffer cotton, and cut the opening on the transparent film; S5. Apply a leak-proof paste on the stoma wound surface within the range of the through hole, place the plugging and guiding unit into the through hole, and inject clean water into the injection channel through a syringe until the outer ring of the leak-proof ring fits against the inner wall of the through hole. Press down the plugging and guiding unit to bond the leak-proof ring with the leak-proof paste. Hold the guiding ring by hand and move the guiding ring close to the lower edge of the through hole until the hydrogel powder solidifies. Along the height direction of the leak-proof ring, cut multiple notches on the part of the leak-proof ring that protrudes above the buffer cotton, and press the part of the leak-proof ring that protrudes above the buffer cotton onto the transparent film. Apply a circle of leak-proof paste on the outer ring of the leak-proof ring pressed on the transparent film. S6. Extract part of the air in the sealed space. S7. Attach the chassis to the transparent film. S8. Install the bag body on the chassis. S9. Continuously input normal saline into the infusion tube. At the same time, suck out the normal saline in the buffer cotton through the liquid suction tube.

[0016] The beneficial effects of the present invention are as follows: 1. By using the stoma care component and its usage method of the present invention, the buffer cotton adheres to the stoma wound surface, which can fill the depression at the stoma and jointly form a good installation base surface with the skin, facilitating the installation of the stoma bag. After the stoma bag is installed, it is not easy to fall off. Inject normal saline into the buffer cotton through the infusion tube and absorb the normal saline in the buffer cotton through the liquid suction tube, which can continuously clean the stoma wound surface and solve the problem of inconvenient cleaning of the stoma wound surface.

[0017] 2. By setting a transparent film and storing hydrogel powder in the transparent film, after injecting clean water into the transparent film through the injection channel, the hydrogel powder will quickly swell and solidify to adapt to through holes of different sizes, greatly improving the adaptability of the plugging and guiding unit. After the hydrogel powder solidifies, it can limit the position of the guiding ring. By controlling the position of the guiding ring during the solidification process of the hydrogel powder, it is beneficial for intestinal contents to flow into the bag body through the guiding ring, and after the hydrogel powder solidifies, it can provide a stable support for the leak-proof ring, improving the stability of the plugging and guiding unit.

Detailed implementation manners

[0020] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that these embodiments are discussed so that those skilled in the art can better understand and thus implement the subject matter described herein. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example may omit, substitute, or add various processes or components as needed. Additionally, features described relative to some examples may be combined in other examples.

[0021] For a better understanding of the present invention, the following will be combined with Figures 1 - 18 A stoma care component of the present invention and its usage method will be described in detail.

[0022] Example 1: As Figures 1 - 5 shown, a stoma care component includes: A cleaning unit 100, including a buffer cotton 110, an infusion tube 120, and a liquid suction tube 130. The buffer cotton 110 completely covers the stoma wound surface 500. The buffer cotton 110 is provided with a through hole 111 corresponding to the intestinal fistula opening 600. A flushing liquid inflow part and a flushing liquid outflow part are respectively arranged in the buffer cotton 110 on both sides of the through hole 111. One ends of the infusion tube 120 and the liquid suction tube 130 are respectively inserted into the flushing liquid inflow part and the flushing liquid outflow part; A plugging and guiding unit 200, connected to the cleaning unit 100, for isolating the intestinal fistula opening 600 from the stoma wound surface 500 and guiding the flow direction of intestinal contents; A stoma bag 300, connected to the plugging unit, for collecting intestinal contents.

[0023] It should be noted that the shape and size of the buffer cotton 110 are cut according to the size of the stoma wound surface 500. The size of the buffer cotton 110 is 5 - 10 mm larger than the edge of the stoma wound surface 500 to ensure that the buffer cotton 110 can always completely cover the stoma wound surface 500, thereby facilitating the cleaning of the stoma wound surface 500. The position, shape, and size of the through hole 111 are cut according to the size of the intestinal fistula opening 600. The size of the through hole 111 is 2 - 3 mm larger than the edge of the intestinal fistula opening 600 to facilitate the installation of the plugging and guiding unit 200; The buffer cotton 110 is attached to the stoma wound surface 500, which can fill the depression at the stoma and facilitate the installation of the ostomy bag 300. Two insertion channels 112 are provided on the buffer cotton 110. One of the insertion channels 112 extends into the flushing liquid inflow part, and the other insertion channel 112 extends into the flushing liquid outflow part. One end of the infusion tube 120 is inserted into one of the insertion channels 112, and the other end of the infusion tube 120 is communicated with an external infusion device. One end of the liquid suction tube 130 is inserted into the other insertion channel 112, and the other end of the liquid suction tube 130 is communicated with an external negative pressure device. The external infusion device injects physiological saline at an appropriate temperature (about 37°C) into the infusion tube 120. The physiological saline flows into the buffer cotton 110 through the infusion tube 120 and diffuses. The external negative pressure device simultaneously generates negative pressure to suck out the physiological saline in the buffer cotton 110 through the liquid suction tube 130. The physiological saline has the functions of sterilization and cleaning. By controlling the temperature of the input physiological saline to be appropriate, the influence of cold stimulation on the patient's stoma and surrounding tissues can be reduced, and the patient's discomfort can be avoided. After the physiological saline flows into the buffer cotton 110 through the infusion tube 120, the buffer cotton 110 can play a buffering role to avoid the mechanical stimulation during direct cleaning, reducing the patient's pain and discomfort. Under the negative pressure generated by the external negative pressure device, the physiological saline in the buffer cotton 110 flows towards the liquid suction tube 130. During this process, the physiological saline can clean the stoma wound surface 500, reduce the risk of continued infection of the stoma wound surface 500, and is beneficial to the growth of granulation in the stoma area and the epithelialization of the wound surface.

[0024] In this embodiment, after the buffer cotton 110 is placed, the stoma wound surface 500 is completely located in the area between the infusion tube 120 and the liquid suction tube 130, thereby improving the overall cleaning effect on the stoma wound surface 500. After the stoma care component is installed, 3000 ml of physiological saline needs to be continuously injected into the infusion tube 120 to remove dirt, bacteria and necrotic tissues in the stoma area and promote the healing of the stoma wound surface 500. Both the infusion tube 120 and the liquid suction tube 130 are transparent flexible tubes. By observing the situation of the physiological saline in the liquid suction tube 130, it is beneficial for doctors to evaluate the cleaning situation of the stoma wound surface 500. If the physiological saline finally absorbed by the liquid suction tube 130 is still turbid and contains impurities after using 3000 ml of physiological saline to clean the stoma wound surface 500, physiological saline can be continuously injected into the infusion tube 120 until the physiological saline in the liquid suction tube 130 is clear and transparent, ensuring that the stoma wound surface 500 is cleaned thoroughly.

[0025] By using the stoma care component of the present invention, the buffer cotton 110 adheres to the stoma wound surface 500 to fill the depression at the stoma, jointly forming a good installation base surface with the skin, facilitating the installation of the ostomy bag 300. After the ostomy bag 300 is installed, it is not easy to fall off. Inject physiological saline into the buffer cotton 110 through the infusion tube 120, and absorb the physiological saline in the buffer cotton 110 through the liquid suction tube 130, which can continuously clean the stoma wound surface 500, solving the problem of inconvenient cleaning of the stoma wound surface 500.

[0026] Embodiment 2: As an optimization of Embodiment 1, as Figures 6 - 8 shown, the part of the infusion tube 120 extending into the buffer cotton 110 is axially provided with a plurality of liquid outlet holes 121 distributed at intervals, and the center line directions of the plurality of liquid outlet holes 121 all face the axis direction of the liquid suction tube 130. The part of the liquid suction tube 130 extending into the buffer cotton 110 is axially provided with a plurality of liquid inlet holes 131 distributed at intervals, and the center line directions of the plurality of liquid inlet holes 131 all face the axis direction of the infusion tube 120. The ends of the infusion tube 120 and the liquid suction tube 130 extending into the buffer cotton 110 are both sealed.

[0027] It should be noted that the distance between adjacent two liquid outlet holes 121 can be the same or different. The liquid outlet holes 121 and the liquid inlet holes 131 can be opened by laser drilling or mechanical drilling. The porosity of the buffer cotton 110 matches the liquid outlet rate of the liquid outlet holes 121 and the liquid suction rate of the liquid inlet holes 131, so that the liquid flowing into the buffer cotton 110 from the liquid outlet holes 121 can be fully diffused in the buffer cotton 110 and then can be sucked into the liquid suction tube 130 through the liquid inlet holes 131. The buffer cotton 110 can be made of materials such as polyurethane, polyvinyl alcohol, and hydrophilic fibers.

[0028] In this embodiment, the infusion tube 120 and the liquid suction tube 130 are arranged parallel to each other. The plurality of liquid outlet holes 121 are equally spaced on the infusion tube 120, the plurality of liquid inlet holes 131 are equally spaced on the liquid suction tube 130, and the liquid inlet holes 131 and the liquid outlet holes 121 correspond one by one. The negative pressure formed in the liquid suction tube 130 is transmitted to the buffer cotton 110 through the liquid inlet holes 131, which is beneficial to the rapid diffusion of the physiological saline flowing into the buffer cotton 110 from the liquid outlet holes 121 towards the liquid suction tube 130, thereby improving the cleaning efficiency.

[0029] Embodiment 3: As an optimization of Embodiment 2, the ratio of the aperture of the liquid outlet hole 121 to the inner diameter of the infusion tube 120 is 0.25 - 0.5, the ratio of the center distance between adjacent two liquid outlet holes 121 to the inner diameter of the infusion tube 120 is 1 - 4, the ratio of the aperture of the liquid inlet hole 131 to the inner diameter of the liquid suction tube 130 is 0.3 - 0.7, and the ratio of the center distance between adjacent two liquid inlet holes 131 to the inner diameter of the liquid suction tube 130 is 1.2 - 5.

[0030] It should be noted that the center distance between two adjacent liquid outlet holes 121 (or liquid inlet holes 131), that is, the straight-line distance between the center lines of two adjacent liquid outlet holes 121 (or liquid inlet holes 131). By controlling the aperture ranges of the liquid outlet holes 121 and the liquid inlet holes 131, it can be ensured that the physiological saline in the infusion tube 120 can smoothly pass through the liquid outlet holes 121 and enter the buffer cotton 110, and the physiological saline in the buffer cotton 110 can smoothly pass through the liquid inlet holes 131 and enter the liquid suction tube 130. Moreover, the infusion tube 120 and the liquid suction tube 130 have sufficient structural strength to facilitate inserting the infusion tube 120 and the liquid suction tube 130 into the insertion channels 112 of the buffer cotton 110.

[0031] In this embodiment, the outer diameters of both the infusion tube 120 and the liquid suction tube 130 are 3 mm, the inner diameters of both the infusion tube 120 and the liquid suction tube 130 are 2 mm, the aperture of the liquid outlet hole 121 is 0.6 mm, the distance between two adjacent liquid outlet holes 121 is 4 mm, the aperture of the liquid inlet hole 131 is 0.8 mm, and the distance between two adjacent liquid inlet holes 131 is 4 mm.

[0032] Embodiment 4: As an optimization of Embodiment 3, as Figure 3 、 Figure 4 、 Figure 9 and Figure 10 shown, a transparent film 400 is attached to the outer side of the buffer cotton 110, and the transparent film 400 is attached to the skin 700 around the buffer cotton 110. The transparent film 400 is provided with an opening 410 corresponding to the through hole 111. The transparent film 400, the plugging and guiding unit 200 and the skin 700 form a sealed space, and the buffer cotton 110 is located in the sealed space.

[0033] It should be noted that the outer side of the buffer cotton 110 is the side of the buffer cotton 110 away from the stoma wound surface 500. One side of the transparent film 400 has adhesiveness, so that the transparent film 400 can fix the buffer cotton 110 on the stoma wound surface 500, and the transparent film 400 covers at least a part of the regions of the infusion tube 120 and the liquid suction tube 130, and fixes a part of the infusion tube 120 and a part of the liquid suction tube 130 on the surface of the patient's skin 700, preventing the infusion tube 120 and the liquid suction tube 130 from shifting in the two insertion channels 112 or even detaching from the buffer cotton 110, thereby affecting the cleaning effect on the stoma wound surface 500; The transparent film 400 can play a blocking role, preventing external bacteria or other contaminants from entering the buffer cotton 110 and then falling on the stoma wound surface 500, which affects the healing of the stoma wound surface 500. The transparent film 400 can also prevent the physiological saline in the buffer cotton 110 from overflowing from the buffer cotton 110, so as to ensure that all the physiological saline flowing into the buffer cotton 110 from the infusion tube 120 can be effectively used for cleaning the stoma wound surface 500; The air in the sealed space can be pumped out through an external negative pressure device and a liquid suction tube 130. As the air is pumped out, the transparent film 400 will squeeze the buffer cotton 110. By observing the squeezing situation of the buffer cotton 110, it is beneficial for the doctor to judge the sealing state of the sealed space, so as to judge the isolation effect of the plugging and diversion unit 200 on the intestinal fistula opening 600 and the stoma wound surface 500. Exemplarily, when a part of the air in the sealed space is pumped out, the buffer cotton 110 is compressed and will not expand again within a short time (10 - 30 s), indicating that the sealing effect of the sealed space is good, the installation of the plugging and diversion unit 200 meets the requirements, and the isolation effect of the plugging and diversion unit 200 on the intestinal fistula opening 600 and the stoma wound surface 500 is good.

[0034] Example 5: As an optimization of Example 4, as Figures 10 - 14 shown, the plugging and diversion unit 200 includes a diversion ring 210, a deformation film 220 and a leak-proof ring 230. The deformation film 220 is of an annular structure. The outer ring of the diversion ring 210 is connected to the inner ring of the deformation film 220. The diversion ring 210 is communicated with the ostomy bag 300. The inner ring of the leak-proof ring 230 is connected to the outer ring of the deformation film 220. Both the deformation film 220 and the leak-proof ring 230 are made of elastic materials. The deformation film 220 is provided with an inner cavity 221. The diversion ring 210 is provided with an injection channel 211 communicated with the inner cavity 221. A seal 240 is arranged at the injection port of the injection channel 211. The gap between the leak-proof ring 230 and the stoma wound surface 500 is filled with leak-proof paste.

[0035] It should be noted that by injecting gas or liquid into the inner cavity 221 of the deformation film 220 through the injection channel 211, the deformation film 220 can be expanded, and then the leak-proof ring 230 can be enlarged until the leak-proof ring 230 completely fits the inner wall of the through hole 111. Then, the gap between the leak-proof ring 230 and the stoma wound surface 500 is sealed with leak-proof paste, which is beneficial to improving the sealing performance and reliability of the sealed space. Moreover, the plugging and diversion unit 200 can adapt to through holes 111 of different sizes and shapes, greatly improving the adaptability of the plugging and diversion unit 200. The intestinal contents flow into the ostomy bag 300 through the diversion ring 210 for collection; both the deformation film 220 and the leak-proof ring 230 can be made of silicone, fluororubber, or other materials with good elasticity and elongation rate.

[0036] In this embodiment, the inner ring of the deformation film 220 is hermetically bonded to the outer ring of the diversion ring 210, and the outer ring of the deformation film 220 is hermetically bonded to the leak-proof ring 230. The leak-proof paste filled in the gap between the stoma wound surface 500 and the leak-proof ring 230 forms a first leak-proof rubber ring 250.

[0037] Example 6: As an optimization of Example 5, the seal 240 is a rubber seal block.

[0038] It should be noted that the injection port of the injection channel 211 is blocked by the rubber sealing block. When the needle of the syringe is inserted and penetrates the rubber sealing block, gas or liquid can be injected into the inner cavity 221 of the deformation membrane 220 through the injection channel 211. After the needle of the syringe is pulled out, the rubber sealing block will rebound, thereby automatically blocking the hole generated by the insertion of the needle to prevent gas or liquid from quickly escaping from the injection channel 211. Then, a layer of leak-proof glue is coated on the surface of the rubber sealing block to completely seal the injection channel 211 and prevent gas or liquid in the inner cavity 221 from escaping, which may cause the deformation membrane 220 and the leak-proof ring 230 to shrink, pulling the stoma wound surface 500 and bringing discomfort to the patient, and even affecting the sealing performance of the sealed space. In addition, by setting the sealing member 240 as a rubber sealing block, the structure is simpler and the operation is more convenient.

[0039] Embodiment 7: As an optimization of Embodiment 6, hydrogel powder is stored in the inner cavity 221 of the deformation membrane 220.

[0040] It should be noted that according to the size of the through hole 111, an appropriate amount of clean water is injected into the inner cavity 221. The hydrogel powder in the inner cavity 221 will absorb water, swell and solidify, thereby limiting the flow guide ring 210 to prevent the frequent displacement of the flow guide ring 210, which may cause discomfort to the patient. And during the process of the hydrogel powder swelling and solidifying, the position of the flow guide ring 210 can be manually adjusted so that the flow guide ring 210 is more conducive to guiding the outflow of intestinal contents after the hydrogel powder solidifies.

[0041] Exemplarily, during the process of the hydrogel powder swelling and solidifying, by holding the flow guide ring 210 by hand, the flow guide ring 210 is made closer to the lower edge of the through hole 111 (the lower edge of the through hole 111 when the patient stands). After the hydrogel powder solidifies, the flow guide ring 210 is also closer to the lower edge of the intestinal fistula opening 600 (the lower edge of the intestinal fistula opening 600 when the patient stands). Under the action of gravity, intestinal contents are more likely to flow into the ostomy bag 300 through the flow guide ring 210.

[0042] Embodiment 8: As an optimization of Embodiment 7, as Figure 10 and Figure 11 shown, the height of the leak-proof ring 230 is greater than the thickness of the buffer cotton 110. A notch is provided on the part of the leak-proof ring 230 that protrudes above the buffer cotton 110. The part of the leak-proof ring 230 that protrudes above the buffer cotton 110 is attached to the transparent film 400, and the gap between the part of the leak-proof ring 230 that protrudes above the buffer cotton 110 and the transparent film 400 is filled with leak-proof paste.

[0043] It should be noted that after the plugging and diversion unit 200 is installed, several notches are cut in the part of the leak-proof ring 230 that is higher than the buffer cotton 110. The cutting direction is along the height direction of the leak-proof ring 230. After cutting, the part of the leak-proof ring 230 that is higher than the buffer cotton 110 is pressed on the transparent film 400, and a leak-proof paste is applied in a circle at the connection part between the leak-proof ring 230 and the transparent film 400, so as to improve the sealing performance of the sealed space.

[0044] In this embodiment, the leak-proof paste filled in the gap between the leak-proof ring 230 and the transparent film 400 forms a second leak-proof rubber ring 260.

[0045] Embodiment 9: As an optimization of Embodiment 8, as Figures 13 - 18 shown, the ostomy bag 300 includes a chassis 310 and a bag body 320. The chassis 310 is detachably connected to the bag body 320. The chassis 310 is attached to the transparent film 400. The chassis 310 is provided with a sleeve hole 311 that cooperates with the diversion ring 210, and the chassis 310 is sleeved on the outer ring of the diversion ring 210.

[0046] It should be noted that the main body of the chassis 310 is made of a hydrogel, and its adhesive surface has adhesiveness. The chassis 310 can be deformed during installation to adapt to an uneven installation base surface. The chassis 310 is attached to the side of the transparent film 400 away from the stoma wound surface 500, so as to fix the chassis 310. The chassis 310 is sleeved on the outer ring of the diversion ring 210. The size of the diversion ring 210 is fixed, and the size of the sleeve hole 311 is also fixed. Compared with the prior art in which the chassis 310 needs to be cut before installation, the chassis 310 of the present invention does not need to be cut additionally, and there will be no situation where the cutting size is inappropriate, which is beneficial to improving the installation efficiency of the chassis 310; The bag body 320 can be detachably connected to the chassis 310 in various ways such as threaded connection, snap connection, and pin connection. Exemplarily, the chassis 310 is provided with an annular groove 312, and a protrusion 321 that cooperates with the groove 312 is provided at the connection port of the bag body 320. By installing the protrusion 321 in the groove 312, the connection between the bag body 320 and the chassis 310 can be realized, and it is convenient to replace the bag body 320. In addition, since the groove 312 is annular, the position state of the bag body 320 can be adjusted by rotating the bag body 320 to improve the comfort of the patient.

[0047] In this embodiment, after the chassis 310 is installed, the inner wall of the sleeve hole 311 fits on the outer surface of the diversion ring 210. The connection gap between the chassis 310 and the diversion ring 210 is filled with a leak-proof paste, and a third leak-proof rubber ring 330 is formed after filling, preventing the intestinal contents flowing out from the diversion ring 210 from entering the connection gap between the chassis 310 and the diversion ring 210 and corroding the plugging and diversion unit 200 for a long time.

[0048] Example 10: A method for using a stoma care component, comprising the following steps: S1. Measure and record the sizes of the stoma wound surface 500 and the intestinal fistula opening 600, as well as the position distribution of the intestinal fistula opening 600 on the stoma wound surface 500; S2. Make the buffer cotton 110; S3. Make the infusion tube 120 and the liquid suction tube 130, and insert them into the buffer cotton 110; S4. Place the buffer cotton 110 on the stoma wound surface 500, and attach and fix the buffer cotton 110 with the transparent film 400, and cut an opening 410 on the transparent film 400; S5. Apply a leak-proof paste on the stoma wound surface 500 within the range of the through hole 111, place the plugging and guiding unit 200 into the through hole 111, and inject clean water into the injection channel 211 through a syringe until the outer ring of the leak-proof ring 230 fits against the inner wall of the through hole 111. Press down the plugging and guiding unit 200 to bond the leak-proof ring 230 with the leak-proof paste. Hold the guiding ring 210 by hand to make the guiding ring 210 close to the lower edge of the through hole 111 until the hydrogel powder solidifies. Along the height direction of the leak-proof ring 230, cut multiple notches on the part of the leak-proof ring 230 that protrudes above the buffer cotton 110, and press the part of the leak-proof ring 230 that protrudes above the buffer cotton 110 onto the transparent film 400, and apply a circle of leak-proof paste on the outer ring of the leak-proof ring 230 pressed on the transparent film 400; S6. Extract part of the air in the sealed space; S7. Stick the chassis 310 on the transparent film 400; S8. Install the bag body 320 on the chassis 310; S9. Continuously input normal saline into the infusion tube 120, and at the same time, suck out the normal saline in the buffer cotton 110 through the liquid suction tube 130.

[0049] It should be noted that in S1, before measurement, the stoma wound surface 500 and its surrounding area are wiped with a clean cotton swab dipped in normal saline (about 37 °C). Among them, the stoma wound surface 500 within 3 mm outward from the edge of the intestinal fistula opening 600 is wiped multiple times to wipe off the obvious dirt and intestinal contents on the stoma wound surface 500, so as to improve the accuracy of the measurement data, and it can be avoided that these relatively large dirt and intestinal contents cannot be sucked into the liquid suction tube 130 through the pores of the buffer cotton 110, thereby affecting the healing of the stoma wound surface 500; In S2, according to the data measured in S1, cut out a buffer cotton 110 with appropriate size on a large cotton board with scissors, and cut out a through hole 111 with appropriate size at the corresponding position, and then drill two insertion channels 112 on the buffer cotton 110 with scissors or other drilling tools; In S3, liquid holes 121 are punched in the infusion tube 120 and liquid inlet holes 131 are punched in the liquid suction tube 130 by means of laser drilling to improve the drilling efficiency and accuracy. Then, the punched ends of the infusion tube 120 and the liquid suction tube 130 are inserted into the buffer cotton 110, with the center line direction of the liquid outlet holes facing the axis direction of the liquid suction tube and the center line direction of the liquid inlet holes 131 facing the axis direction of the infusion tube 120. In S4, release films are attached to both sides of the transparent film 400. The two release films are torn off, and the sticky side of the transparent film 400 is pasted on the stoma wound surface 500 area to fix the buffer cotton 110. The opening 410 cut on the transparent film 400 corresponds to the position of the through hole 111 and has the same size. In S5, when initially placing the plugging and guiding unit 200 into the through hole 111, the plugging and guiding unit 200 is only placed into 1 / 2 - 4 / 5 of the depth of the through hole 111. After the clean water injection is completed, leak-proof paste is applied at the position where the syringe needle is inserted into the rubber sealing block. When holding the guiding ring 210 by hand, it is only necessary that the hydrogel powder is cured to a certain extent so that it can maintain its shape and limit the guiding ring 210.

[0050] In S6, start the external negative pressure device. The air in the sealed space can be pumped out through the liquid suction tube 130, and the sealing performance of the sealed space is detected by observing the state of the buffer cotton 110. If the sealing performance of the sealed space is not good, the plugging and guiding unit 200 needs to be reinstalled. In S7, when pasting the chassis 310, the sleeve hole 311 of the chassis 310 is aligned with the guiding ring 210, so that the chassis 310 is sleeved on the outer ring of the guiding ring 210, and a circle of leak-proof paste is applied at the connection gap between the chassis 310 and the guiding ring 210. In S9, under normal circumstances, the external infusion device continuously inputs 3000 ml of normal saline into the infusion tube 120 at one time. After the stoma wound surface 500 is cleaned, the infusion tube 120 and the liquid suction tube 130 are removed, and the tube openings of the infusion tube 120 and the liquid suction tube 130 can be sealed by tying knots to prevent external bacteria and pollutants from entering.

[0051] The embodiments of the invention have been described above in conjunction with the accompanying drawings. However, the present embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present embodiment, those of ordinary skill in the art can also make many forms without departing from the purpose of the present embodiment and the scope protected by the claims, and all of them fall within the protection scope of the present embodiment.
