Description

Technical Field

[0001] The utility model relates to the technical field of ostomy bags, in particular to an ostomy bag discharge valve. Background Art

[0002] There are many kinds of urinary ostomy bags commonly found on the market. One kind is a ostomy bag without a discharge port. This kind of ostomy bag is disposable and can only be thrown away after use, which has a high cost of use. The second kind is a ostomy bag with a discharge port, which is clamped by a sealing clamp device. When the excrement in the ostomy bag needs to be poured out, the sealing clamp device can be opened. Although this kind of ostomy bag can be reused, the sealing clamp device is easy to be lost and damaged on the one hand, and on the other hand, when the sealing clamp device is opened, the excrement is easy to overflow in large quantities at once, which is easy to dirty hands and clothes;

[0003] To this end, there is a public technology on the market that proposes an ostomy bag, which has a back side of the ostomy bag, a front side of the ostomy bag and a collection port. The front side of the ostomy bag is provided with a first hard thin plate, a second hard thin plate, a third hard thin plate and a membrane in order from bottom to top, and the membrane is provided with a second buckle. The back side of the ostomy bag is provided with a first buckle parallel to the second buckle. The first hard thin plate can be folded upward to overlap the first hard thin plate. This improved technical solution completely seals the ostomy bag by folding the ostomy bag three times, and there will be no leakage problem. Each fold is slowly opened so that urine will not pour out all at once, and it is not easy to dirty hands and clothes. In addition, the ostomy bag itself is made of a soft plastic film, so it can be bent many times without breaking.

[0004] However, when using the above-mentioned improved technology, it is necessary to unfasten the buckle and slowly open the fold to discharge urine. In fact, the last folding may still cause urine to gush out instantly, and the discharge effect cannot be controlled. There is still the possibility of soiling clothes, and the closing and opening operations are very troublesome. Therefore, it is necessary to improve the structure of the ostomy bag excretion valve used in the urinary tract. Utility Model Content
