Abstract:

Provided is a liquid handling device comprising: a cylindrical actuator cavity in a substrate, the actuator cavity intersected by two or more actuator channels; one or more chambers with an access channel adapted to connect to a separate one of actuator channels; and a actuator comprising (a) a cylindrical body having a cylinder axis and having therein a liquid-handling compartment with, arrayed along the cylinder axis, a first end and a second end, the liquid-handling compartment being closed at the second end, (b) a dispensing channel located at the second end and traversing the cylindrical body, the dispensing channel adapted to be separately aligned with the actuator channels, wherein the actuator is adapted to receive in a seal-tight manner a plunger that operates to confine an effective chamber defined by the plunger and the second end by moving toward the second end or to expand the effective chamber by moving toward the first end. Preferably, one or more of the chambers are formed within the substrate.

US Classification:

604378, 604322, 604355, 604356, 604358

Abstract:

A controlled evacuation ostomy appliance including a collection pouch, and an urging device for applying a sealing force through the pouch wall to seal the stoma. The pouch wall may seal directly against the stoma, or the pouch may have an internal sealing member that is pressed by the pouch wall against the stoma. The urging device provides an adjustable sealing force. The pouch may be disposable. The urging device may be reusable with a replacement pouch.

International Classification:

A61M 1/00

US Classification:

604317, 604 9301

Abstract:

A tube assembly for carrying malodoriforous matter from the human body comprises a silicone based tube having a central bore for the malodoriforous matter, and a tubular sleeve member comprising an odor barrier material, the silicone based tube and the tubular sleeve member being arranged one within the other such that the tubular sleeve member provides an odor barrier to obstruct leakage of odors from malodoriforous matter in the bore of the silicone based tube. The tube assembly is especially suitable for use in fecal or bowel management apparatus.

International Classification:

A61F 2/02

US Classification:

600032000

Abstract:

A stoma seal is described for a controlled evacuation ostomy appliance. The stoma seal may have a liquid-responsive property, such as hydrophobic, hydrophilic or absorptive. The stoma seal may have a non-smooth surface, e.g., at a microstructure scale. The non-smooth surface may consist of tortuous channels, protruding seals, or a confronting apertured or porous layer. The liquid-responsive property and/or the non-smooth surface may facilitate separation of flatus from faecal matter and/or facilitate venting of flatus while obstructing stool.

International Classification:

A61F 5/44

US Classification:

604335000, 604337000

Abstract:

A controlled evacuation ostomy appliance comprises a membrane that is urged into sealing engagement with a stoma, by the generation of radial tension in the membrane. A tensioning device applies tension, with respect to the stoma, at one or more positions that are (i) outboard of the periphery of the projecting portion of the stoma, and/or (ii) between the level of the peristomal skin and the level of the most projecting part of the stoma. Tension limiting means are disclosed. The membrane may be gas-permeable to allow flatus to be vented.

International Classification:

A61F 5/44

US Classification:

604328

Abstract:

A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.
