An ostomy appliance having an appliance wall of flexible sheet material forming a cavity for containing a stomal output. The wall has a stomal inlet for receiving the stomal output and a gas vent for allowing the stomal gas to migrate out of the cavity. A filter arrangement is mounted to the appliance wall and has a filter channel extending from a filter channel inlet to a filter channel outlet. The filter channel inlet is located in the cavity for receiving the stomal output from the cavity and the filter channel outlet is mounted in communication with the gas vent for allowing stomal gas to migrate out of the filter channel to the gas vent. A separation element extends along the filter channel for maintaining the filter channel in an open configuration along part of the filter channel for allowing stomal gas to pass therethough.

An ostomy appliance includes an outer wall having first and second opposed sides joined at an outer periphery, an inlet and a filter assembly, wherein the outer wall defines an interior volume comprising a collection area and a filter flow path in fluid communication with the collection area. The filter flow path fluidically connects the filter assembly to the collection area. The ostomy appliance further includes one or more flow elements between the first side and the second side, the one or more flow elements disposed between the collection area and the filter assembly. The one or more flow elements may be sized and arranged to permit gas venting from the collection area to the filter assembly and restrict liquid and/or solid flow from the collection area to the filter assembly.

An ostomy bag can include one or more sensors for measuring one or more metrics. An ostomy wafer can also include one or more sensors for measuring one or more metrics. The sensors can be temperature sensors and/or capacitive sensors, for example, and the metrics can include bag fill, leakage, skin irritation, and phase of stoma output, among others.

Embodiments herein relate to an ostomy bag filter. In an embodiment, a filter assembly for venting gas from an ostomy bag is included having a first layer, an adhesive layer, an adsorbent element, and a second layer, the second layer configured to be welded to the ostomy bag at an annular weld area surrounding the second opening; wherein the adhesive layer is configured to adhere to the first layer, the adsorbent element, and the second layer, such that the first opening overlaps with the second opening; wherein the filter assembly is configured such that, when the filter assembly is welded over to the ostomy bag, gas from the ostomy bag flows axially through the adsorbent element and exits the filter assembly through the second opening; and wherein perimeters of the first layer, the adhesive layer, and the second layer are substantially aligned. Other embodiments are also included herein.

An ostomy appliance having a releasable receptacle for concealing an ostomy bag where the receptacle is asymmetrical and includes an enlarged cavity portion and expandable portion located below the stoma which provides additional area into which the bag may unroll as waste collects therein. In an alternate embodiment there is no bag and waste collects directly into the receptacle.
