  • Patent number: 10576262
    Abstract: A spring-loaded bag connector having a spring-loaded valve and a housing comprising a fluid inlet portion and a fluid outlet portion. The spring-loaded bag connector is configured to connect with a fluid collection bag to generate a self-closing collection bag. Additionally, the spring-loaded bag connector is configured to couple with a second coupling element, such as a coupling connector, to facilitate the drainage and collection of waste to a fluid collection bag. Uncoupling of the bag connector and the second coupling element results in minimal fluid contamination on the outer surfaces of the bag connector system. The bag connector systems provided herein are included in medical appliances for body waste management.

  • Patent number: 9636249
    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.

  • Patent number: 9623201
    Abstract: The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port. A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

  • Patent number: 9526816
    Abstract: A stand-alone system for assessing wound exudates from the wound of a patient is described. The system contains 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 also compare 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 the comparison result in which the electronic signal may corresponds to guidelines for treating the wound (3). The system described may be an accessory, which may be used on its own, or in conjunction with other wound treatment devices (9).
