Abstract
Description
Technical Field
[0001] This utility model relates to an ostomy bag, and in particular discloses an ostomy bag sealing ring with an adsorption function that can be replaced. Background Technology
[0002] Ostomy bags are mainly used to collect excrement after enterostomy. Enterostomy is a relatively common surgery that usually involves pulling out a section of the intestine from the abdominal cavity and excreting feces through an opening in the skin of the abdominal wall. Special ostomy bags are usually used to collect urine and feces. This surgery is particularly necessary for patients with intestinal obstruction, familial adenomatous polyposis, bladder tumors, and congenital anal atresia, as it can improve the condition and prevent it from worsening. After the surgery, it is important to maintain local hygiene. Iodine or alcohol can be used to wipe the area, which can have an anti-inflammatory and bactericidal effect to prevent infection at the stoma site.
[0003] Ostomy bags on the market are connected to a sealing ring via an adhesive layer. The bottom of the sealing ring is adhered to the patient's skin for fixation. To ensure the ostomy bag's stability during use, the adhesive layer is very sticky, making it difficult to tear open when changing the bag. Changing the sealing ring at the same time can pull on the patient's skin, causing significant discomfort. Furthermore, excrement can easily remain in the ostomy bag during each change, leading to skin infections during ostomy bag and sealing ring care. Residual solution at the threads of the sealing ring can also cause infections. Tearing the ostomy bag or sealing ring too quickly or too slowly during each change can also cause leakage, hindering proper care. Summary of the Invention
[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a replaceable ostomy bag sealing ring with adsorption function that is simple in structure, easy to disassemble, and prevents leakage during replacement.
[0005] This invention is implemented as follows: A replaceable ostomy bag sealing ring with adsorption function includes an installation ring, a fixing device, a bolt, and a clamping ring for fixing the ostomy bag opening. The middle part of the fixing device is hollow and tubular, the upper part of the fixing device is an annular groove, and the lower part of the fixing device is a connecting ring connected to the bottom of the annular groove. The outer diameter of the connecting ring is smaller than the outer diameter of the annular groove. The annular groove is located above the installation ring, and the connecting ring is inserted into the installation ring. The bottom of the annular groove has 2-4 first through holes. The clamping ring is located in the annular groove, and there is a gap for placing the ostomy bag between the clamping ring and the annular groove. The clamping ring has a second through hole corresponding to the first through hole, and the installation ring has a fixing screw hole corresponding to the first and second through holes. The bolt passes through the second through hole and the first through hole from top to bottom and is connected and fixed to the fixing screw hole.
[0006] The ostomy bag placement gap is located between the inner wall of the compression ring and the inner side wall of the annular groove, and a sealing ring is provided between the outer wall of the compression ring and the outer side wall of the annular groove.
[0007] The connecting ring has vertical pins on its side wall, and the mounting ring has limiting slots on its inner wall that correspond to the vertical pins.
[0008] The outer diameter of the mounting ring is equal to the outer diameter of the fixing device.
[0009] An elastic sealing ring is provided on the bottom surface inside the annular groove, and the elastic sealing ring is provided with an opening corresponding to the first through hole.
[0010] The bottom surface of the mounting ring is provided with an adhesive layer.
[0011] The beneficial effects of this utility model are: the ostomy bag opening is pressed and fixed in the annular groove of the fixing device by the clamping ring and bolts. During disassembly, the ostomy bag can be replaced and re-fixed simply by using bolts. This facilitates disassembly and assembly while preventing external force from pulling the ostomy bag. While fixing the clamping ring and fixing device, the bolts further connect the fixing device to the mounting ring, which facilitates the overall disassembly and cleaning of the fixing device and prevents contaminants inside the ostomy bag from contaminating the mounting ring.

Detailed Implementation
[0015] according to Figure 1 , Figure 2 This utility model relates to a replaceable ostomy bag sealing ring with adsorption function, comprising a mounting ring 1, a fixing device 2, a bolt 3, and a compression ring 4 for fixing the opening of the ostomy bag 5. The fixing device 2 has a hollow tubular middle section, an annular groove 6 at its upper part, and a connecting ring 7 at its lower part connected to the bottom of the annular groove 6. The outer diameter of the connecting ring 7 is smaller than the outer diameter of the annular groove 6. The annular groove 6 is located above the top of the mounting ring 1, and the connecting ring 7 is inserted into the mounting ring 1. The side wall of the connecting ring 7 is provided with a vertical insertion foot 8, and the inner wall of the mounting ring 1 is provided with a limiting slot 9 corresponding to the vertical insertion foot 8. The outer diameter of the mounting ring 1 is equal to the outer diameter of the fixing device 2.
