The present invention comes under the category of medical equipment. Individuals who have undergone a colostomy operation are compelled to use a prosthesis which is generally designated by the name of a colostomy bag and which, when applied on the artificial anus, is intended to collect the intestinal waste. It appears that some disadvantages which they suffer from in their present design were due to an internal excess pressure of the bag. The author of the present invention proposes novel bags which are all equipped with a device by means of which it is possible to control the internal pressure of the said bags.
