Description

Invasive and non-invasive dual-purpose anal canal

technical field

The utility model relates to the technical field of medical devices, in particular to an invasive and non-invasive dual-purpose anal canal.

Background technique

The structure of the existing anal canal is relatively simple, only a hose with an inner diameter of about 12 mm, the head of the hose is inserted into the patient's anus, and the tail is placed in the collection bottle, thereby realizing the drainage of stool. The fixation effect of this anal canal is poor and it is easy to prolapse. For patients with loose anus, the indwelling effect is poor, and the stool is easy to flow out from the side of the anus, causing pollution; at the same time, the hose is easy to prolapse from the collection bottle, which will also cause pollution. The collection bottle is also not conducive to subsequent processing. Part of the improved anal canal is provided with an airbag at the head, and the airbag is inflated and fixed after being inserted into the anus. Although the fixation effect is improved, the airbag is likely to cause damage to the patient's rectum.
