Patent number: 11898678Abstract: A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.Type: GrantFiled: November 30, 2021Date of Patent: February 13, 2024Assignee: ConvaTec Technologies Inc.Inventors: Yun Jin, Bret Weig, John Cline, Mingliang Lawrence Tsai

Publication number: 20220054297Abstract: 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.Type: ApplicationFiled: November 1, 2021Publication date: February 24, 2022Inventors: John Cline, Bret Weig, Christopher Gregory, John Blum

Patent number: 11076978Abstract: A controlled discharge ostomy appliance assembly comprises (i) a stoma seal that is self-urging with a dynamic damping characteristic that resists changes of seal volume, (ii) a press-fit coupling member displaceable from an unlocked position to a locked position as part of a press-fit process, and (iii) a single-use frangible portion. The assembly further includes a protector shield removably fastened to the appliance forming a combined assembly therewith. The protector shield comprises (i) a seal displacer manipulable for displacing the stoma seal to a non-operative position ready for fitting, (ii) a substantially rigid coupling member guard portion for protecting the state of the coupling member, and (iii) a bracing portion for bracing the single-use frangible portion.Type: GrantFiled: April 16, 2018Date of Patent: August 3, 2021Assignee: CONVATEC TECHNOLOGIES INC.Inventors: Tinh Nguyen-Demary, John Cline, John Blum, Gary Stacey, Philip Davies, Trevor Beckett

Publication number: 20170281397Abstract: 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.Type: ApplicationFiled: March 20, 2017Publication date: October 5, 2017Inventors: Geraint Davies, John Cline, Christopher C.
