Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a stoma chassis. Background Art

[0002] Approximately 100,000 patients undergo colostomy surgery in my country each year. After surgery, a stoma tray is placed over the stoma, secured with a stoma belt to ensure a closer fit between the tray and the surrounding skin, reducing the risk of leakage. However, the incidence of colostomy complications within 30 days of surgery is as high as 63%, with peristomal skin complications being the most common. These skin complications are often attributed to improperly cut stoma trays.

[0003] The stoma baseplate currently used in clinical practice needs to be cut according to the size of the patient's stoma, and there are circular cutting scale marks on the plate to facilitate user cutting. However, the stoma shape of some patients is elliptical, which requires marking the long axis and short axis of the stoma before cutting. Since patients need to wear a stoma belly belt, the belly belt buckle on the stoma baseplate must be parallel to the transverse axis of the body. Therefore, when facing a stoma with an inclined long axis and short axis, in addition to determining the length of the long axis and short axis of the stoma, the angle with the transverse axis of the body should also be determined. Only in this way can the position of the endpoints of the long and short axes be accurately marked, so that the cut stoma baseplate can match the shape of the patient's stoma; however, when facing such a stoma with an inclined long axis and short axis, it is often difficult for patients and their families to accurately locate the cutting position of the existing stoma baseplate, resulting in a mismatch between the cut shape and the stoma shape, which in turn causes skin complications. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a stoma base plate which can accurately locate the cutting position.

[0005] The technical solution of the utility model is to provide a stoma base plate with the following structure:

[0006] It includes a disc body and a convex ring connected to the disc body, and two symmetrically arranged abdominal belt buckles are connected to the outer peripheral wall of the convex ring, and the abdominal belt buckles are used to connect the stoma abdominal belt; two positioning rulers made of flexible material are rotatably connected to the disc body, and the rotating shafts of the two positioning rulers are set concentrically with the convex ring; a number of size marks are provided on the positioning ruler, and the size marks are evenly spaced from one end of the positioning ruler rotating shaft to the other end.

[0007] After adopting the above structure, the stoma base plate of the present invention has the following advantages compared with the prior art:

[0008] The utility model provides two rotatable positioning rulers on the tray body. When using the stoma tray, first place it on the stoma so that the belly belt buckle is parallel to the horizontal axis of the patient's body. Then, rotate the two positioning rulers so that they are respectively located on the long axis and short axis of the stoma. After marking the end points of the long axis and short axis of the stoma with a marker, remove the stoma tray and cut the tray body with scissors. Under the positioning marks of the positioning rulers, the user can accurately find the end points of the long axis and short axis of the stoma, so that the cut shape fits the stoma shape perfectly, thereby reducing the occurrence of skin complications.

[0009] Preferably, the disc body is provided with a central hole which is cocentric with the convex ring, and the outer edge of the central hole protrudes axially to form the rotating shaft of the positioning ruler.

[0010] Preferably, the hinged end of the positioning ruler is provided with an axial hole for the shaft to pass through, and the outer end of the shaft extends radially to form a retaining ring. The inner diameter of the axial hole is larger than the outer diameter of the shaft and smaller than the outer diameter of the retaining ring. The positioning ruler is made of a flexible material with a certain degree of elastic deformation. During assembly, only slight force is required to pass the free end of the shaft through the axial hole, thus completing the assembly of the positioning ruler. Furthermore, because the inner diameter of the axial hole is smaller than the outer diameter of the retaining ring, the positioning ruler will not easily fall off the shaft.

[0011] Preferably, the disc body and the rotating shaft are integrally formed, which can reduce the processing steps and save production costs.

[0012] Preferably, a side wall of the positioning ruler is provided with a plurality of marking notches corresponding to the size marks one by one, for facilitating marking with a marker pen.

[0013] Preferably, the positioning ruler is made of a thin transparent material. The disc body is usually provided with a plurality of circular dimension markings concentric with the convex ring. The positioning ruler is set to be transparent to facilitate user observation and marking. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown; the utility model discloses a stoma chassis: it includes a disc body 1 and a convex ring 2 connected to the disc body 1, and two symmetrically arranged abdominal belt buckles 3 are connected to the outer peripheral wall of the convex ring 2, and the abdominal belt buckles 3 are used for connecting the stoma abdominal belt; two positioning rulers 4 made of flexible material are rotatably connected to the disc body 1, and the rotating shafts 5 of the two positioning rulers 4 are arranged concentrically with the convex ring 2; a plurality of size marks 41 are provided on the positioning ruler 4, and the size marks 41 are evenly spaced from one end of the rotating shaft 5 of the positioning ruler 4 to the other end.

[0023] The utility model provides two rotatable positioning rulers 4 on the tray body 1. When using the stoma tray, first place it on the stoma so that the belly belt buckle 3 is parallel to the horizontal axis of the patient's body. Then, rotate the two positioning rulers 4 so that they are respectively located on the long axis and short axis of the stoma. After marking the end points of the long axis and short axis of the stoma with a marker, remove the stoma tray and cut the tray body 1 with scissors. Under the positioning marks of the positioning rulers 4, the user can accurately find the end points of the long axis and short axis of the stoma, so that the cut shape fits the stoma shape perfectly, thereby reducing the occurrence of skin complications.

[0024] The disc body 1 is provided with a central hole 11 which is coaxial with the convex ring 2 , and the outer edge of the central hole 11 protrudes axially to form the rotating shaft 5 of the positioning ruler 4 .

The inner diameter of the shaft hole 42 is larger than the outer diameter of the shaft 5, but smaller than the outer diameter of the retaining ring 51. The positioning ruler 4 is made of plastic and has a certain degree of elastic deformation. During assembly, only a slight force is required to insert the free end of the shaft 5 through the shaft hole 42, thus completing the installation of the positioning ruler 4. In addition, because the inner diameter of the shaft hole 42 is smaller than the outer diameter of the retaining ring 51, the positioning ruler 4 will not easily fall off the shaft 5.

[0026] The disc body 1 and the rotating shaft 5 are integrally formed, which can reduce the processing steps and save production costs.

[0027] A plurality of marking notches 43 corresponding to the size markings 41 are provided on one side wall of the positioning ruler 4 for facilitating marking with a marker pen.

[0028] The positioning ruler 4 is made of a thin sheet of transparent plastic; since the disk body 1 is usually provided with a plurality of circular dimension markings concentric with the convex ring 2, the positioning ruler 4 is set as a transparent sheet, which is not only convenient for users to observe and mark, but also can be easily cut off together with the positioning ruler 4 during cutting.

[0029] The above is only a specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
