The shape of the tray 101 may be determined according to actual requirements, and as shown in fig. 1 and 3, the tray 101 may preferably adopt a circular structure, a square structure, and the like.
To facilitate cutting of the tray 101 with scissors, as shown in fig. 1 and 3, the tray 101 is centrally configured with an opening 102, the opening 102 typically having a size much smaller than the stoma 302;
as shown in fig. 1 and fig. 3, in this embodiment, an adhesive 106 for adhering is disposed on one side of the tray body 101, a protective layer 107 for protecting the adhesive 106 covers the adhesive 106, and the protective layer 107 can be made of a film or release paper preferentially, so that the purpose of protecting the adhesive 106 can be achieved by covering the adhesive 106, and the adhesive can be torn easily, and meanwhile, the film or the release paper has good waterproof performance, so that water entering the color development layer 201 can be effectively prevented from contacting the adhesive 106, the purpose of isolation protection can be achieved, and the waterproof problem of the adhesive 106 can be solved.
As shown in fig. 1 and fig. 3, in the present embodiment, a color development layer 201 is disposed on a surface of the protection layer 107 away from the adhesive 106, for example, the color development layer 201 may be disposed on the protection layer 107 in a sticking manner, and the color development layer 201 is made of a water-encountering color-changing material so as to change color when encountering water; there are many materials that change color when they are exposed to water in the prior art, for example, as shown in fig. 1 and 3, the color developing layer 201 may be made of iodine-containing paper or PH paper so as to show different colors when it is exposed to water, thereby forming a distinct boundary with the surrounding non-exposed portion so as to cut along the boundary.
With this ostomy tray 100, the present embodiment further provides a method of accurately cutting the ostomy tray 100, comprising the steps of:
step one, wetting the stoma or the contours of the stoma with water 303 or a liquid containing water, as shown in fig. 4; for example, in a clinical setting, a cotton swab may be used to dip in fresh water to wet the stoma 302, and in one embodiment, the user may entirely wet the exposed end of the stoma, which may be suitable for smaller stoma areas; in another embodiment, the user may also wet only along the edge of the stoma 302, i.e. only the contours of the stoma, which is suitable for situations with a large stoma area.
Step two, a user holds the tray body 101 and aligns the opening 102 with the stoma 302, as shown in fig. 5, the center of the opening 102 can be generally corresponding to the center (geometric center) of the stoma, and then the user can attach the color-developing layer 201 of the tray body 101 to the stoma 302, i.e. the color-developing layer 201 is in contact with the end surface of the stoma 302, and after the contact, the portion of the color-developing layer 201 which meets water automatically changes color and forms a color-changing area 202, as shown in fig. 6, the shape of the color-changing area 202 is the shape of the end surface of the stoma, and the size of the color-changing area 202 is the size of the end surface of the stoma;
step three, the user can hold the tray body 101 with one hand and hold scissors with the other hand to cut the tray body 101 along the contour of the color-changing area 202, so that a through hole 203 matched with the shape of the stoma can be formed at the middle position of the tray body 101, as shown in fig. 7 and 8.
