1. A medical device for controlling the release of waste content from an external stoma of a subject, comprising:
a first flange;
wherein the first flange comprises a vent hole and a vent cover for releasing gas waste content;
an adhesive layer bound to the first flange for attaching to the body of the subject;
a second flange, wherein the first and second flanges are connectable or connected;
a displaceable cover for closing and opening the device,
wherein the displaceable cover is configured to connect to the second flange;
an aperture configurated to surround the stoma for the release of waste content;
an ostomy bag system;
a pressure sensor for determining the pressure of the subject's waste content in the displaceable cover, wherein the pressure sensor is between the displaceable cover and the ostomy bag system;
an alert system; and
a data processor configured to activate the alert system when the pressure is equal or superior to a predetermined threshold.
