Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of medical devices, and specifically relates to an ostomy bag chassis and an ostomy bag assembly. Background Art
[0002] A stoma is an opening created in the abdomen when lesions occur in the rectum or other parts of the body. In order to protect the patient, the doctor removes the lesion and creates an opening in the abdomen. The stoma needs to be connected to the patient's digestive tract or urethra so that the patient's urine, feces and other excreta can be discharged from the body through the stoma.
[0003] An ostomy bag is a medical device that needs to be placed at the stoma position. The stoma enters the bag body through a hole provided on the bottom plate of the ostomy bag. The ostomy bag is used to store human excrement such as urine or feces discharged through the stoma.
[0004] After total pelvic organ resection, the colostomy and urinary stoma are close to each other, and the two stoma bag bases overlap. The stoma bag base cannot fully adhere to the skin. Due to the influence of factors such as patient activities, a gap appears between the stoma bag base and the skin. The body fluid near the stoma can easily flow to the outside through the gap between the two, polluting the environment near the stoma and staining the patient's clothes. When the patient has just completed the operation, the wound near the stoma has not healed yet, and the exudate at the stoma greatly increases the risk of wound infection.
[0005] When exudate appears at the stoma, it needs to be replaced in time to prevent the exudate from soaking the skin and causing dermatitis, and to avoid stoma infection. However, the price of a single stoma bag base is relatively high, and both stoma bag bases and both stoma bags need to be replaced. Under normal circumstances, the stoma bag base is generally replaced every three to five days. If exudate occurs, it needs to be replaced immediately. Exudate from the stoma bag base will increase the financial burden on the patient. Utility Model Content
[0006] In order to avoid the situation where the two ostomy bag bases overlap due to the two stomas being close to each other, and a gap appears between the ostomy bag base and the skin, resulting in the ostomy bag being connected to the outside world through the gap, the present application provides an ostomy bag base and an ostomy bag assembly.
[0007] A stoma bag chassis comprises a working portion and a plurality of tear strips, wherein the working portion is provided with a connecting ring that can be connected to a bag opening of the stoma bag, the plurality of tear strips are connected to the outer edge of the working portion, the tear strips are connected in sequence along the radial outward direction of the connecting ring, and the tear strips can be separated from the other tear strips to change the spacing between the connecting ring and the edge of the stoma bag chassis.
[0008] In one embodiment of the present application, the radially outward direction of the connecting ring includes a first straight line direction; along the first straight line direction, the working portion and the plurality of easy-tear strips are arranged in sequence.
[0009] In an embodiment of the present application, the ostomy pouch chassis includes two working parts, and a plurality of tear strips are provided between the two working parts. When one of the tear strips is separated from the other tear strips, the distance between the two connecting rings can be reduced.
[0010] In an embodiment of the present application, the plurality of tear strips are arranged in an array around the connecting ring, and the plurality of tear strips are coaxially arranged with the connecting ring.
[0011] In an embodiment of the present application, the ostomy pouch chassis further includes a connecting film. When one of the tear strips is separated from the other tear strips, the connecting film connects the working part and the tear strip connected to the working part.
[0012] In an embodiment of the present application, the connecting film is provided with an adhesive layer, and the connecting film connects the working part and the tear strip connected to the working part by gluing, so as to facilitate operation.
[0013] In an embodiment of the present application, along the arrangement direction of the plurality of tear strips, the working part and each tear strip are provided with scales.
[0014] In an embodiment of the present application, the tear strip is provided with an adhesive layer.
[0015] In an embodiment of the present application, the adhesive layers of the respective tear strips are respectively covered with release paper.
[0016] An ostomy pouch assembly includes an ostomy pouch chassis of any one of the above structures, and further includes an ostomy pouch body. The ostomy pouch chassis is connected to the ostomy pouch body, and the ostomy pouch body can communicate with the connecting ring.

[0031] Please refer to Figures 1 to 6 to understand the present application.
[0032] The ostomy pouch chassis 101 includes a working part and a plurality of tear strips 103. The working part is provided with a connecting ring 102 capable of connecting with the opening of the ostomy pouch. The plurality of tear strips 103 are connected to the outer edge of the working part. The tear strips 103 are sequentially connected along the direction radially outward from the connecting ring 102. The tear strips 103 can be separated from other tear strips 103 to change the distance between the connecting ring 102 and the edge of the ostomy pouch chassis 101, and reduce the size of the ostomy pouch chassis 101.
[0033] See Figure 1 , Figure 2 , in an embodiment of the present application, the direction radially outward from the connecting ring 102 includes a first linear direction; along the first linear direction, the working part and the plurality of tear strips 103 are sequentially arranged to Figure 2 be described based on the direction in Figure 2 , on the rightward direction in
[0034] Those skilled in the art to which the present application pertains can understand that the arrangement manner of the tear strips 103 in the present application is not limited to the manner of arranging the plurality of tear strips 103 in an array along the first linear direction, and other manners are also possible.
[0035] In an embodiment of the present application, the plurality of tear strips 103 are arranged in an array around the connecting ring 102, and the plurality of tear strips 103 are coaxially arranged with the connecting ring 102. See Figure 3 , the plurality of tear strips 103 are circular, the diameters of the plurality of tear strips 103 gradually increase, the plurality of tear strips 103 are coaxially arranged with the connecting ring 102, and the innermost tear strip 103 is connected to the connecting ring 102, and the remaining tear strips 103 are sequentially arranged along the direction radially outward from the connecting ring 102. When there is an overlapping situation between two ostomy pouch chassis 101, the outer tear strips 103 are torn off to reduce the size of the ostomy pouch chassis 101, thereby avoiding the overlapping between the ostomy pouch chassis 101 and preventing the situation that the ostomy pouch chassis 101 cannot fully fit the skin near the stoma.
[0036] Those skilled in the art to which the present application pertains can understand that the ostomy pouch chassis 101 capable of reducing size in the present application can be used in pairs, and can also be used in combination with an ostomy pouch chassis that cannot change its size, so as to avoid overlap between the ostomy pouch chassis 101 by reducing the size of the ostomy pouch chassis 101.
[0037] Certainly, those skilled in the art to which the present application pertains can understand that in an embodiment of the present application, two connecting rings 102 can be provided on the same ostomy pouch chassis 101. The ostomy pouch chassis 101 includes two working parts. Refer to Figure 4 , a plurality of tear strips 103 are provided between the two working parts. The plurality of tear strips 103 are arranged in a straight line direction between the two connecting rings 102. When one tear strip 103 is separated from the other tear strips 103, the length of the ostomy pouch chassis 101 of the ostomy pouch can be reduced, and the distance between the two connecting rings 102 can be reduced. Refer to Figure 5 . When the distance between two stomas on the patient's skin surface is small, the number of tear strips 103 between the two connecting rings 102 can be reduced, so that the distance between the two connecting rings 102 can be reduced, so that the two connecting rings 102 can be installed on the two stomas, avoiding the situation that when the two connecting rings 102 are respectively sleeved on the two stomas due to the closeness of the two stomas, the distance between the two connecting rings 102 is large, while the distance between the two stomas is close, resulting in bulges and wrinkles in the ostomy pouch chassis 101 between the two connecting rings 102, so that the ostomy pouch chassis 101 cannot completely fit the skin, and finally resulting in the situation of liquid leakage.
[0038] In an embodiment of the present application, the ostomy pouch chassis 101 further includes a connecting film. When one tear strip 103 is separated from the other tear strips 103, that is, when the outer tear strip 103 is separated from the inner tear strip 103, the connecting film connects the working part and the tear strip 103 connected to the working part. Further, the connecting film is provided with an adhesion layer, and the adhesion layer is a medical-grade adhesive such as plaster glue or hydrocolloid. The connecting film connects the two separated working parts through adhesive bonding.
[0039] Refer to Figure 5 , after removing an appropriate number of tear strips 103, the connecting film is adhered to the bag body connection surface 104 of the ostomy pouch chassis 101 to connect the two working parts and the plurality of tear strips 103, so as to strengthen the connection effect between the remaining tear strips 103 and the working parts, ensure the adhesion effect between the ostomy pouch chassis 101 and the skin, and avoid the separation between the tear strips 103.
[0040] Refer to Figure 2 、 Figure 4 、 Figure 5, in an embodiment of the present application, along the arrangement direction of the plurality of tear strips 103, the working part and each tear strip 103 are provided with scales 106, and the scale 106 is provided on the bag body connection surface 104 of the ostomy bag chassis 101. The distance between two stomas can be determined through the scale 106, and then the number of tear strips 103 to be removed can be determined by the user through the scale 106, so as to ensure that the two connecting rings 102 can be accurately sleeved on the two stomas, and there will be no wrinkles on the ostomy bag chassis 101 between the two connecting rings 102.
[0041] In an embodiment of the present application, see Figure 6 , the tear strip 103 is provided with an adhesion layer, and the adhesion layer is formed by a medical-grade glue such as plaster glue. The bonding surface 105 of the ostomy bag chassis 101 is provided with glue, and the adhesion layer of each tear strip 103 is respectively covered with a release paper 201. See Figure 6 , each tear strip 103 is respectively provided with a piece of release paper 201, and the adhesion layer of each tear strip 103 adheres to the release paper 201. When it is necessary to separate the tear strip 103, the release paper 201 can fit on the tear strip 103. Along with the separation of the tear strip 103 from other tear strips 103, it is avoided that the release paper 201 connects multiple tear strips 103 and the situation where the release paper 201 hinders the separation of the tear strip 103 from other tear strips 103; and the release paper 201 separates along with the tear strip 103, which can avoid the tear strip 103 from adhering to the user's finger or other positions, facilitating the separation of the tear strip 103 from other tear strips 103.
