DETAILED DESCRIPTION

[0065] The present disclosure relates to a compact medical device and a method for controlling the release of waste content from an external stoma of a subject, comprising: a flange; wherein the flange comprises a vent hole and a vent cover for releasing gas waste content; an adhesive layer bound to the flange for attaching to the body of the subject; a displaceable cover for closing and opening the device, wherein the displaceable cover is configured to connect to the flange; an aperture configurated to surround the stoma for the release of waste content.

[0066] The following figures provide preferred embodiments for illustrating the description and should not be seen as limiting the scope of disclosure.

[0067] In an embodiment, the device of the present disclosure is totally waterproof, washable and non-invasive. It is composed by an exterior component 13, with minimalist design, and a front opening through a displaceable cover 4.

[0068] In an embodiment, the device of the present disclosure is fixed to the body through an adhesive layer 6, like the ones already existing in the market, therefore preventing the release of faeces, gases and smells in an uncontrolled way. Its fixing point occurs over the abdominal wall and does not require any extra surgical intervention.

[0069] In an embodiment, inside the device of the present disclosure there is a disposable component 13, composed by a fully compacted colostomy bag 5, resembling an airbag-like system. Between this component and the ostoma, there is a vent cover 7, with odour neutralizer 8, for gas release control. Between the displaceable cover 4 and the colostomy bag 5 system, there is a pressure sensor 9. Once the intestinal content starts exerting pressure, predetermined to safe and adequate pressure values, the sensor 9 inside the device activates an electronic alert 12 (vibratory, sonorous or bright sign), synchronised with, for example, a smartphone app, that informs the patient about the need to go to an appropriate place for releasing the intestinal content.

[0070] In an embodiment, the relief of intestinal pressure, which may be due to faeces or gases, can be distinguished in two different ways, depending on the reason for the sensor 9 activation:

[0071] In an embodiment, if there are gases inside the device 13, they are released through the activation of a vent cover 7;

[0072] In an embodiment, if there are faces inside the device, the user just has to open the displaceable cover 4 and automatically, due to pressure variation, the collection bag 5 inside the equipment, properly compacted, will expand and fill with faecal content. Once the release is over, the user removes the biodegradable bag component 5, does the sanitation and substitutes it for a new one.

[0073] In an embodiment, the device engages the fastening system by engagement and rotation, followed by a click ensuring the correct fixation of the piece. So that it does not inadvertently disengage, its unlock will have to be activated through a simultaneous manual pressure of one point and rotation of the entire piece (second flange 2 and first flange 1). When the predefined pressure of the intestinal content is reached, the pressure sensor 9 will activate the alert system 12 that will send a sign, vibratory, sonorous, bright and/or to a smartphone app, informing the user to the need of going to a proper place in order to empty the collection bag 5.

[0074] In an embodiment, the user will have to manually activate the vent valve to purge gases. This action will relieve the pressure therefore deactivating the alert system 12. If the alarm does not deactivate, the user will have to manually open the upper cover 4 and the pressure relieve will occur naturally, inflating the ostomy bag 5 in the device with intestinal content. Then, the user will remove de collecting bag 5 already full, do the sanitation and put a new bag 5, closing the displaceable cover 4.

[0075] In an embodiment, the device 13 is properly sealed so that the electrical and electronic systems 10, 11 and 12 will not be damaged while in use. The fast engagement systems (second flange 2 and first flange 1) in the device, besides user friendly are also watertight, to prevent any unpleasant surprises to the user.

[0076] In an embodiment, the electrical energy supply to the device comes from a battery 10, easily recharged by the user, through an access in the device 13.

[0077] In an embodiment, the disclosure is totally removable, washable and sterilizable, so that the user can clean it whenever necessary.

[0078] The term comprising whenever used in this document is intended to indicate the presence of stated features, integers, steps, components, but not to preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.

[0079] It will be appreciated by those of ordinary skill in the art that unless otherwise indicated herein, the particular sequence of steps described is illustrative only and can be varied without departing from the disclosure. Thus, unless otherwise stated the steps described are so unordered meaning that, when possible, the steps can be performed in any convenient or desirable order.

[0080] The disclosure should not be seen in any way restricted to the embodiments described and a person with ordinary skill in the art will foresee many possibilities to modifications thereof. The above described embodiments are combinable. The following claims further set out particular embodiments of the disclosure.
