Description

Technical Field

[0001] The utility model relates to the technical field of urinary ostomy bags, in particular to a variable anti-reflux urinary ostomy bag. Background Art

[0002] A urostomy bag is an auxiliary medical device product used to collect urine outside the body. It belongs to the category of home care medical devices. After bladder cancer patients are hospitalized, they usually undergo a radical cystectomy to prevent the disease from worsening. After the cystectomy, a urethral diversion is required, and a fistula is created at the patient's waist to drain human urine. This stoma often requires a urostomy bag to collect urine. However, there are still some defects in the actual use of urostomy bags.

[0003] Urinary ostomy bags are often directly bonded to the patient's skin with medical tape, and it is not easy to flexibly change the wearing method according to the patient's usage needs, which leads to its poor flexibility. In addition, when the urine collection bag is under pressure or collision, urine reflux is prone to occur, which leads to low safety of the device, no anti-reflux urinary tract, infection at the patient's ostomy, and difficulty in promotion.

[0004] Existing anti-reflux urostomy bags, such as the Chinese utility model patent with application number CN202220406996.6, disclose an anti-reflux urostomy bag, including a first bag body film, a second bag body film, and an anti-reflux layer film, etc., by providing an anti-reflux layer film between the first bag body film and the second bag body film, so that a space in direct contact with the stoma is formed between the second bag body film and the anti-reflux layer film, and a storage space is formed between the first bag body film and the second bag body film, so that excrement can flow smoothly from the contact space through the separation gap into the storage space, while also achieving the purpose of anti-reflux. However, this kind of anti-reflux structural design will still cause reflux when the urine collecting bag is under pressure or collision, and cannot achieve complete sealing of the reflux circuit, and the use effect is not good.
