In addition, it is desirable that the diameter is slightly smaller when the pipe is installed together with a pipe or the like which is retained for drainage.

An integral type having an anal canal insert and a perianal covering is advantageous for use in a wide range of diseases. The combination of the portion inserted into the anal canal and the portion surrounding the anus may be the same material or a combination of different materials. Even when the same material is used, since the required characteristics of the insertion portion in the anal canal and the required characteristics of the anal peripheral covering portion are different, it is desirable to make the characteristics different.

The shape of the anal peripheral covering portion must be a string shape, a sheet shape, a bulky cotton shape, and have flexibility so that it can be applied to any portion around the anal canal. More preferably, the structure is such that the width, thickness, and the like can be changed according to the shape of the diseased part. For this purpose, it is preferable that the anal peripheral covering portion is formed into a string-like fiber aggregate, nonwoven fabric, woven fabric, cotton-like material, porous sheet or ribbon.
