Abstract
An ostomy apparatus comprising a flexible container having an interior chamber for receiving waste from a patient's stoma and an opening for surrounding the stoma, a housing coupled to the container, wherein the housing is configured to accommodate an absorbent material that surrounds the stoma, a port configured to provide fluid communication between the housing and a pressure source; and an adhesive layer configured to seal the housing to skin around the stoma.
Claims19
An ostomy apparatus comprising:
- an ostomy bag comprising:
- a flexible container having:
- an interior chamber configured to receive waste from a patient's stoma,
- a first end defining a first opening configured to surround the stoma and receive the waste into the interior chamber;
- and
- a first locking ring coupled to the first end of the flexible container;
- a wafer configured to accommodate an absorbent material that surrounds the stoma, the wafer comprising:
- a second locking ring configured to engage with the first locking ring to couple the ostomy bag to the wafer;
- a second opening configured to surround the stoma and receive the waste from the stoma and into the interior chamber while the first and second locking rings are engaged;
- a port provided in the wafer and configured to provide fluid communication between an interior of the wafer and a pressure source, wherein the port is isolated from fluid communication with the first and second openings;
- and
- an adhesive layer having a first side coupled the wafer and a second side configured to be coupled to skin to seal the wafer to the skin around the stoma.
9 more elements
An ostomy apparatus comprising:
- an ostomy bag comprising:
- a flexible container having a receptacle for receiving waste from a patient's stoma and;
- a first lock assembly defining a first opening configured to surround the stoma and receive the waste into the receptacle;
- and
- a wafer configured to surround the stoma and accommodate an absorbent material, the wafer comprising:
- a second lock assembly configured to engage with the first lock assembly to couple the ostomy bag to the wafer;
- a second opening configured to surround the stoma and receive the waste from the stoma and into the receptacle when the first and second lock assemblies are engaged;
- a port provided in the wafer and configured to provide fluid communication between an interior of the wafer and a pressure source, wherein the port is isolated from fluid communication with the first and second openings;
- and
- an adhesive layer configured to couple the wafer to skin surrounding the stoma.
7 more elements
A method of collecting waste from a stoma of a patient, the method comprising:
- adhering an adhesive layer to skin surrounding the stoma;
- coupling a wafer to the adhesive layer, the wafer including:
- an interior chamber;
- an absorbent material disposed within the chamber;
- a wafer locking assembly having a first opening;
- and
- a port provided in the wafer and configured to provide fluid communication between the interior chamber and a pressure source;
- coupling an ostomy bag having a flexible container and a container locking assembly to the wafer such that the wafer locking assembly engages the container locking assembly, wherein the flexible container includes a receptacle configured to receive waste from the stoma and a second opening for surrounding at least a portion of the stoma;
- and
- communicating fluid between the chamber of the wafer and a pressure source such that pressure within the chamber of the wafer is sub-atmospheric;
- wherein the port is isolated from fluid communication with the first and second openings.
