  • Patent number: 10507318
    Abstract: 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.

  • Patent number: 10406277
    Abstract: A rectal drainage appliance is disclosed comprising a tubular element having an inflatable balloon at a distal end for anchoring the appliance in the rectum. The appliance includes one or more of: (i) first and second auxiliary lumens communicating with the inflatable balloon to provide independent inflation and pressure monitoring paths coupled to the balloon; (ii) a pressure state indicator defined by a mechanical element configured to flip between first and second states or shapes responsive to sensed pressure; and (iii) a collapsible auxiliary lumen larger than the inflation lumen, and configured to permit admission of irrigation fluid. The pressure state indicator may also be used in intestinal drains.

  • Patent number: 10207031
    Abstract: An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.

  • Patent number: 10166138
    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.

  • Patent number: 9707120
    Abstract: An ostomy appliance comprises a pouch having first and second walls, with an inlet aperture in the first wall. A stoma seal is carried by the second wall, and is disposed generally in register with the inlet aperture for sealing against a stoma in use. An outer coupling element is coupled to the first wall and surrounds the inlet aperture. An inner coupling element for supporting the stoma seal, is coupled to the second wall and/or to the stoma seal. The outer coupling element surrounds a periphery of the inner coupling element. The stoma seal may be of an inflatable type or an insertable type. Manipulation tabs may be provided associated with the inner and outer coupling elements.
