[0001] The present invention relates to a stoma appliance, and particularly to a stoma appliance that is attached to a gastrointestinal stoma such as an artificial anus and collects human excrement.

Background Art

[0002] When there are diseases such as digestive and urinary diseases, or when excretion cannot be controlled at will, the digestive tract or urinary tract may be led to the body surface to create a stoma (artificial anus, artificial bladder, etc.) on the body surface. Since excretion cannot be self-controlled at the stoma, a bag (stoma appliance) for temporarily storing excrement and the like from the stoma is attached to the stoma opening.

[0003] Conventionally, various such stoma appliances have been developed mainly for the purpose of deodorization and the like. As a further improvement, a stoma appliance that can easily remove excrement in a bag (pouch) for collecting excrement has been proposed. <0000**********]]

[0004] For example, in Patent Document 1, a stoma bag used for a stoma appliance is proposed, which includes an inlet for receiving excrement in communication with the stoma and an openable and closable outlet for removing excrement outside the bag, and a functional layer containing at least one kind of functional particles of hydrophobic particles and lipophobic particles is formed as the outermost layer on at least a part of the inner surface of the stoma bag.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. The embodiments described below show an example of typical embodiments of the present invention, and thus the scope of the present invention is not limited thereby, and various combinations, modifications, and changes are possible within the scope of the gist.

[0013] <First Embodiment> Referring to FIGS. 1 to 3, a configuration example of a stoma appliance according to the first embodiment of the present invention will be described. FIG. 1 is a plan view showing the skin-contact side of the stoma appliance 10 according to the present embodiment attached to the human body. FIG. 2 is a bottom view showing the non-skin-contact side opposite to the side attached to the human body of the stoma appliance 10. FIG. 3 is a perspective view showing a state where the discharge port 18 of the stoma appliance is open.

[0014] vinegar The stoma appliance 10 includes a storage part 11 for storing waste, a discharge port 18 for discharging the stored waste from the storage part 11 to the outside, and a discharge path 17 connecting the storage part 11 and the discharge port 18.

[0015] ​The discharge passage 17 is a hollow passage communicating with the containment section 11, and has a base end 22 connected to the containment section 11 and a tip end 19 formed at a position away from the containment section 11. The discharge port 18 is located inside the discharge passage 17 between the base end 22 and the tip end 19. The discharge port 18 can be moved by sliding its tip end 19 towards the containment section 11 by folding (rolling up) the tip end 19 to the outside of both sides of the discharge passage 17. As a result, the discharge port 18 is exposed from the inside to the outside of the discharge passage 17. Here, the inside of the discharge passage refers to the inside of the passage through which waste products pass, and the outside of the discharge passage refers to the outside of the passage.

[0016] Furthermore, the stoma appliance 10 includes a pair of tip plates 13 attached to the tip 19 of the drainage passage 17, and the outer surface of the drainage passage 17 on the side of the housing 11 that is closer to the tip 19 of the drainage passage 17. It comprises a pair of inner plates 14 attached to it.

[0017] As shown in Figure 3, the stoma appliance 10 further comprises a pair of reversal plates 21 attached to the outer surface of the drainage passage 17 between the tip portion 19 of the drainage passage 17 to which the tip plate 13 is attached, and the drainage port 18. The reversal plates 21 are formed in a semi-elliptical shape with two protrusions projecting toward the tip plate 13 from the circumference, but are not limited to this, and can be rectangular, X-shaped, circular, elliptical, polygonal, or a combination thereof, as long as they have the function of causing the tip portion 19 to curl outwards and pushing the drainage port 18 toward the tip side of the tip plate 13. In this embodiment, the drainage port 18 is located between the inner plate 14 and the reversal plates 21 in the extension direction of the drainage passage 17. In this embodiment, the tip plate 13, the reversal plates 21, and the inner plate 14 are referred to as the first plate, the second plate, and the third plate, respectively. These plates are preferably made of an elastic material such as polyethylene, polypropylene, or nylon.

[0018] Returning to Figures 1 and 2, the stoma appliance 10 is provided with a faceplate portion 12 on the skin-contacting side of the housing portion 11. This allows the stoma appliance 10 to be attached to a gastrointestinal stoma, etc. The stoma appliance 10 is provided with a skin-contacting side joint portion 15 on the skin-contacting side of the housing portion 11 and a non-skin-contacting side joint portion 16 on the non-skin-contacting side of the housing portion 11. These allow the discharge passage 17 and discharge port 18 to be rolled up and stored outside the housing portion 11. The skin-contacting side joint portion 15 and the non-skin-contacting side joint portion 16 are preferably formed by hook-and-loop fasteners. For example, the skin-contacting side joint portion 15 and the non-skin-contacting side joint portion 16 may be formed by a pair of loop surfaces and hook surfaces. Note that the housing portion 11 shown in Figures 1 and 2 is formed of a transparent material as an example. Therefore, as shown in Figure 1, when the stoma appliance 10 is viewed from the skin contact side, the non-skin contact side joint 16 provided on the non-skin contact side may be visible. Also, as shown in Figure 2, when the stoma appliance 10 is viewed from the non-skin contact side, the skin contact side joint 15 provided on the skin contact side may be visible.

[0019] In the stoma appliance 10 according to this embodiment, the outlet 18 can be opened by pushing both ends of the pair of tip plates 13 toward the center with a person's fingers or the like while sliding them toward the housing portion 11.

[0020] Next, the operation of opening the outlet 18 of the ostomy appliance 10 will be explained with reference to Figures 3 to 6. Figure 4 is a schematic diagram showing the state in which the outlet 18 of the ostomy appliance 10 is closed. Figure 5 is a schematic diagram showing the state in which the tip plate 13 and the inner plate 14 overlap and the outlet 18 of the ostomy appliance 10 is open. Figure 6 is a schematic diagram showing the state in which the outlet 18 of the ostomy appliance 10 is open with the inner plate 14 positioned further forward than the tip plate 13. Figures 4 to 6 are all schematic diagrams of the ostomy appliance 10 as seen from the skin contact side.

[0021] First, with the outlet 18 closed, as shown in Figure 4, i.e., not exposed, both ends of the pair of tip plates 13 are pushed towards the center with a finger or the like, as shown in Figure 3. As a result, the pair of tip plates 13, which were overlapping each other, curve outwards, and the space between the pair of tip plates 13 opens up.

[0022] Next, as the pair of tip plates 13 separate, the pair of reversing plates 21, which were positioned inside the pair of tip plates 13, reverse as they move, biasing the tip plates 13 toward the housing 11. As a result, the pair of tip plates 13 slide toward the housing 11, reaching the state shown in Figure 5.

[0023] In the state shown in Figure 5, if only both ends of the pair of tip plates 13 are pushed further towards the center, as shown in Figure 6, the pair of inverting plates 21 will be completely inverted, and the pair of inner plates 14 will slide further towards the tip than the position of the pair of tip plates 13. Then, the discharge passage 17 will be turned outward, and the discharge port 18 will open. By opening the discharge port 18, the waste products accumulated in the storage section 11 will be discharged to the outside through the discharge passage 17 and the discharge port 18.

[0024] After the waste products are discharged, the pair of tip plates 13 are slid from the housing section 11 side to the discharge port 18 side, and the discharge port 18 and discharge passage 17 are rewound inward, returning to the original state shown in Figure 4. After use, the discharge passage 17 can be folded and rolled up, and the skin-contact side joint 15 is bonded to the non-skin-contact side joint 16, so that the discharge passage 17 can be stored outside the housing section 11.

[0025] According to the stoma appliance 10 of this embodiment, by sliding the pair of tip plates 13, which are folded back to the outside of the discharge passage 17, toward the housing section 11, the pair of inverted plates 21 are inverted, and the pair of inner plates 14 are positioned further toward the tip than the position of the pair of tip plates 13. As a result, in the stoma appliance 10, the discharge port 18 is exposed to the outside and opens, so the outer surface of the stoma appliance 10 and the inner surface of the discharge passage 17 toward the tip of the discharge port 18 are less likely to get dirty, and the work of wiping away dirt around the discharge port 18 can be reduced.

[0026] Furthermore, since the stoma appliance 10 includes a pair of tip plates 13, a pair of inversion plates 21, and a pair of inner plates 14, the outlet 18 can be easily opened and closed with just one hand. Note that the tip plates 13, inversion plates 21, and inner plates 14 are not limited to a pair (two plates) but may each consist of only one plate. Also, the width of the pair of tip plates 13 may be wider than the width of the outlet 18, which will enable easier and smoother movement.

[0027] <Second Embodiment> Next, a stoma appliance according to a second embodiment of the present invention will be described with reference to Figures 7 and 8. Figure 7 is a schematic diagram showing the outlet 18 of the stoma appliance 20 according to this embodiment in a closed state. Figure 8 is a schematic diagram showing the outlet 18 of the stoma appliance 20 in an exposed state.

[0028] The difference between the stoma appliance 20 according to this embodiment and the stoma appliance 10 according to the first embodiment is that it has one rectangular inverted plate near the outlet 18, and does not have an inner plate. The other components of the stoma appliance 20 are the same as those of the stoma appliance 10.

[0029] As shown in Figures 7 and 8, the stoma appliance 20, similar to the stoma appliance 10 according to the first embodiment, allows the tip portion 19 formed at the end of the drainage passage 17 to be folded back to the outside of both sides of the drainage passage 17, thereby enabling the tip portion 19 to slide and move toward the housing portion 11 (in the direction of the arrow in Figure 8).

[0030] The stoma appliance 20 comprises a pair of tip plates 23 attached to the tip 19 of the drainage passage 17, and a single reversal plate 21 attached to the outer surface of the drainage passage 17 at a position opposite to the tip 19 of the drainage passage 17 to which the tip plates 23 are attached. In this embodiment, the width of the pair of tip plates 23 is wider than the width of the drainage opening 18.

[0031] According to the stoma appliance 20 of this embodiment, similar to the stoma appliance 10 of the first embodiment, by pushing both ends of the pair of tip plates 13 toward the center with a person's finger or the like, one inverted plate 21 is inverted, and the outlet 18 is brought forward relative to the tip of the pair of tip plates 23 and opened. As a result, in the stoma appliance 20, the outlet 18 is exposed to the outside and opens, so the outer surface of the stoma appliance 20 and the inner surface of the outlet passage 17 on the tip side of the outlet 18 are less likely to get dirty, and the work of wiping away dirt around the outlet 18 can be reduced.

[0032] Furthermore, since the stoma appliance 20 is equipped with a pair of tip plates 23 and a pair of inverting plates 21, the outlet 18 can be easily opened and closed with just one hand. In particular, since the width of the pair of tip plates 23 of the stoma appliance 20 is wider than the width of the outlet 18, the movement of the pair of tip plates 23 can be made even easier and smoother.

[0033] <Third Embodiment> Next, a stoma appliance according to a third embodiment of the present invention will be described with reference to Figures 9 and 10. Figure 9 is a schematic diagram showing the outlet 18 of the stoma appliance 30 according to this embodiment in a closed state. Figure 10 is a schematic diagram showing the outlet 18 of the stoma appliance 30 in an exposed state.

[0034] The difference between the stoma appliance 30 according to this embodiment and the stoma appliance 10 according to the first embodiment is that it has one tip plate near the outlet 18, and does not have an inverting plate or an inner plate. The other components of the stoma appliance 30 are the same as those of the stoma appliance 10.

[0035] As shown in Figures 9 and 10, the stoma appliance 30 includes a single tip plate 33 attached to the tip 19 of the drainage channel 17. The tip 19 of the drainage channel 17, formed at the end of the drainage channel 17, is folded outwards on both sides of the drainage channel 17, allowing the tip 19 to slide and move toward the housing 11 (in the direction of the arrow in Figure 10).

[0036] In the ostomy appliance 30, by supporting both ends of the tip plate 33 with the fingers of one hand and pushing the discharge passage 17 connected to the housing 11 toward the tip plate 33 with the other hand, the discharge port 18 can be brought out and opened toward the tip side of the tip plate 33.

[0037] Therefore, with the stoma appliance 30, even without an inversion plate and an inner plate, simply by having one tip plate 33, the outlet 18 can be brought out and opened relative to the tip side of the tip plate 33 by using both hands or the like. As a result, in the stoma appliance 30, the outlet 18 is exposed to the outside and opens, so the outer surface of the stoma appliance 30 and the inner surface of the outlet passage 17 on the tip side of the outlet 18 are less likely to get dirty, and the work of wiping away dirt around the outlet 18 can be reduced.

[0038] <Fourth Embodiment> Next, a stoma appliance according to the fourth embodiment of the present invention will be described with reference to Figures 11 and 12. Figure 11 is a schematic diagram showing the outlet 18 of the stoma appliance 40 according to this embodiment in a closed state. Figure 12 is a schematic diagram showing the outlet 18 of the stoma appliance 40 according to this embodiment in an exposed state.

[0039] The difference between the stoma appliance 40 according to this embodiment and the stoma appliance 10 according to the first embodiment is that it comprises a tip plate, an inverting plate, and an inner plate. points that are missing The other components of the stoma appliance 40 are the same as those of the stoma appliance 10.

[0040] As shown in Figures 11 and 12, in this embodiment, the stoma appliance 40 has a tip portion 41 of the discharge channel 17 that is wider than the width of the outlet 18. Furthermore, the tip portion 41 of the discharge channel 17, which is formed at the end of the discharge channel 17, is folded back on both sides of the discharge channel 17, making it possible to slide the tip portion 41 toward the housing portion 11 (in the direction of the arrow in Figure 12).

[0041] In this embodiment, the stoma appliance 40 can be opened by supporting the tip portion 41 with the fingers of one hand and pushing the discharge passage 17 connected to the storage portion 11 toward the tip portion 41 with the other hand, thereby bringing the discharge port 18 toward the tip side of the discharge passage 17.

[0042] According to the stoma appliance 40, it comprises an end plate, an inverting plate, and an inner plate. Even without a person present, since the tip 41 of the discharge channel 17 is folded back on both sides of the discharge channel 17, the outlet 18 can be brought out and opened relative to the tip of the discharge channel 17 by using both hands or the like. As a result, the outlet 18 is exposed and opened to the outside, making it less likely for the outer surface of the stoma appliance and the inner surface of the discharge channel 17 on the tip side of the outlet 18 to get dirty, thus reducing the amount of cleaning work required around the outlet 18.

[0043] Furthermore, in this embodiment, the stoma appliance 40 has a tip portion 41 of the drainage passage 17 that is wider than the width of the drainage opening 18, which allows the tip portion 41 to move more easily and smoothly.

[0044] <Fifth Embodiment> Next, a stoma appliance according to the fifth embodiment of the present invention will be described with reference to Figures 13 and 14. Figure 13 is a bottom view showing the non-skin contact side opposite to the side attached to the human body of an example of the configuration of the stoma appliance 50 according to this embodiment. Figure 14 is a schematic diagram showing the state in which the inner plate 14 is positioned closer to the tip than the tip plate 13 after the tip portion 19 has been moved.

[0045] The differences between the stoma appliance 50 according to this embodiment and the stoma appliance 10 according to the first embodiment are that the stoma appliance 50 has a first joint portion 51 on the inner surface of the tip plate 13 of the tip portion 19 that is folded back to the outside of the drainage passage 17, and a second joint portion 52 on the outer surface of the drainage passage 17. The inner surface of the tip plate 13 is, in other words, the surface of the tip plate 13 that faces the drainage passage 17. The other components of the stoma appliance 50 are the same as those of the stoma appliance 10.

[0046] As shown in Figure 13, the first joint 51 may be provided, for example, on the inner surface of the non-skin contact side of the tip plate 13. In this case, the second joint 52 is provided on the outer surface of the non-skin contact side of the drainage passage 17. Preferably, the second joint 52 is provided on the outer surface of the non-skin contact side of the drainage passage 17 at a position corresponding to the skin contact side joint 15. That is, in a bottom view of the stoma appliance 50 (Figure 13), the second joint 52 provided on the non-skin contact side and the skin contact side joint 15 provided on the skin contact side are positioned to overlap each other.

[0047] The first joint 51 and the second joint 52 are preferably formed by hook-and-loop fasteners. For example, the first joint 51 and the second joint 52 may be formed by a pair of loop faces and hook faces.

[0048] As shown in Figures 13 and 14, the ostomy appliance 50, like the ostomy appliance 10 according to the first embodiment, allows the pair of tip plates 13 to slide and move toward the housing portion 11 (in the direction of the arrow in Figure 14).

[0049] As shown in Figure 14, the first joint 51 and the second joint 52 can be joined. Specifically, the first joint 51 can be joined to the second joint 52 after moving the tip 19 toward the housing 11. As shown in Figure 14, when the first joint 51 and the second joint 52 are joined, if both ends of the pair of tip plates 13 are pushed toward the center with a person's fingers or the like, the pair of tip plates 13 will bend outward. At this time, the discharge passage 17 (specifically the surfaces constituting the discharge passage 17) is pulled by the tip plates 13 and bends outward in the same way as the tip plates 13. Therefore, the operation of opening the closed discharge passage 17 and discharge port 18 can be performed more easily. In other words, the load of the opening operation can be reduced by joining the first joint 51 and the second joint 52.

[0050] Furthermore, the connection between the first joint 51 and the second joint 52 suppresses displacement of the tip plate 13. Specifically, it prevents the tip plate 13 from moving and shifting position while the waste product accumulated in the storage section 11 is being discharged.

[0051] As described above, the stoma appliance 50 shown in Figures 13 and 14 has a first joint 51 on the inner surface of the tip plate 13 on the non-skin contact side. However, the position of the first joint is not limited to this.

[0052] <Example 1> As an example, the stoma appliance may have a first joint on the inner surface of the tip plate 13 on the skin-contacting side. In this case, the stoma appliance may have a second joint on the outer surface of the drainage passage 17 on the skin-contacting side, or it may not have a second joint. If the stoma appliance does not have a second joint, the first joint may be connectable to the skin-contacting side joint 15 after the tip portion 19 has been moved toward the housing portion 11. By connecting the first joint and the skin-contacting side joint 15 after moving the tip portion 19, it is possible to obtain an effect that reduces the load of opening operations and suppresses displacement of the tip plate 13, similar to the stoma appliance 50 shown in Figure 14. Thus, when the first joint is provided on the inner surface of the tip plate 13 on the skin-contacting side, the second joint is not an essential component.

[0053] <Modification 2> As another example, the stoma appliance may have a first joint on the inner surface of the tip plate 13 on the non-skin contact side and the inner surface of the tip plate 13 on the skin contact side. That is, the first joint may be provided in at least two locations, on the non-skin contact side and the skin contact side. In this case, the stoma appliance may have a second joint on the outer surface of the drainage passage 17 on the non-skin contact side and the outer surface on the skin contact side. That is, the second joint may be provided in at least two locations, on the non-skin contact side and the skin contact side. The first joint on the non-skin contact side can be joined to the second joint on the non-skin contact side, and the first joint on the skin contact side can be joined to the second joint on the non-skin contact side. Furthermore, in the above case, the stoma appliance does not have to have a second joint on the skin contact side. In this case, the first joint on the skin-contacting surface side may be connectable to the skin-contacting surface side joint 15 after the tip portion 19 has been moved toward the housing portion 11. By connecting the first joint on the skin-contacting surface side and the skin-contacting surface side joint 15 after moving the tip portion 19, it is possible to obtain an effect that reduces the load of opening operations and suppresses displacement of the tip plate 13, similar to the stoma appliance 50 shown in Figure 14. Thus, when the first joint is provided on the inner surface of the tip plate 13 on the skin-contacting surface side, the second joint on the skin-contacting surface side is not an essential component.

[0054] The first and second joints described in the fifth embodiment may be combined not only with the configurations of the first embodiment but also with those of the second to fourth embodiments.

[0055] For example, the stoma appliance 20 according to the second embodiment may have a first joint on the inner surface of the tip plate 23. Also, the stoma appliance 20 according to the second embodiment may have a second joint on the outer surface of the drainage passage 17.

[0056] For example, the stoma appliance 30 according to the third embodiment may have a first joint on the inner surface of the tip plate 33. Also, the stoma appliance 30 according to the third embodiment may have a second joint on the outer surface of the drainage passage 17.

[0057] For example, the stoma appliance 40 according to the fourth embodiment may have a first joint on the inner surface of the tip portion 41 that is folded outwards from the drainage passage 17. Alternatively, the stoma appliance 40 according to the fourth embodiment may have a second joint on the outer surface of the drainage passage 17.

[0058] If the stoma appliance according to the second to fourth embodiments includes a first joint, or includes a first joint and a second joint, the details of the first joint and the second joint may be as described in the fifth embodiment.

[0059] <Sixth Embodiment> Next, a stoma appliance according to the sixth embodiment of the present invention will be described. The stoma appliance according to the sixth embodiment has the advantage of being able to easily open the outlet, which has become difficult to open due to the accumulation of waste products. Before describing the details of the sixth embodiment, first, the operation of opening the outlet will be described with reference to Figures 3 to 6, which show the stoma appliance 10 according to the first embodiment.

[0060] In the stoma appliance 10 according to the first embodiment, when the outlet 18 is opened and waste products are discharged to the outside through the procedure shown in Figures 3 to 6, waste products (especially feces) adhere to the inside of the outlet 18. Subsequently, when attempting to close the outlet 18 and then reopen it, the waste products adhering to the inside of the outlet 18 may make it difficult to open. In this case, even if one attempts to open the outlet 18 using the procedure shown in Figures 3 to 6, for example, the outlet 18 may not open completely.

[0061] In such cases, the outlet 18 may be opened by an opening operation different from that shown in Figures 3 to 6, for example, as shown in Figures 15 and 16. Figures 15 and 16 are schematic diagrams showing the operation of opening the outlet 18 of the stoma appliance 10 according to the first embodiment. First, as shown in Figure 15, fingers (for example, the thumb and index finger) are inserted between the pair of tip plates 13 and the outer surface of the outlet passage 17, and then, as shown in Figure 16, the fingers are spread apart to open the outlet 18. By performing such an opening operation, the outlet 18, which may have become difficult to open due to the accumulation of waste products, can be easily opened. Note that this opening operation may be performed regardless of whether or not waste products are attached to the outlet 18.

[0062] Next, as an example of an embodiment that allows for a different opening operation than described above, a stoma appliance according to the sixth embodiment will be described with reference to Figures 17 and 18. Figures 17 and 18 are schematic diagrams showing the operation of opening the outlet 18 of the stoma appliance 60 according to this embodiment.

[0063] The difference between the stoma appliance 60 according to this embodiment and the stoma appliance 10 according to the first embodiment is that a finger can be inserted between the pair of inner plates 14A and the outer surface of the drainage passage 17. The other components of the stoma appliance 60 are the same as those of the stoma appliance 10. Furthermore, the pair of inner plates 14A of the stoma appliance 60 are the same as the pair of inner plates 14 of the stoma appliance 10, except that they are configured to allow finger insertion as described above.

[0064] To open the outlet 18 of the stoma appliance 60 according to this embodiment, first, as shown in Figure 17, insert your fingers (for example, your thumb and index finger) between the pair of inner plates 14A and the outer surface of the outlet 17, and then, as shown in Figure 18, spread your fingers apart to open the outlet 18. By performing this opening operation, the outlet 18, which may have become difficult to open due to the accumulation of waste products, can be easily opened. Note that this opening operation may be performed regardless of whether or not waste products are attached to the outlet 18.

[0065] The pair of inner plates 14A may be partially joined to the outer surface of the discharge passage 17, for example, so that fingers can be inserted as described above. That is, a portion of the inner surface of the pair of inner plates 14A may be joined to the outer surface of the discharge passage 17. The portion where the pair of inner plates 14A and the outer surface of the discharge passage 17 are not joined corresponds to the portion into which fingers can be inserted.
