  • Publication number: 20240009372
    Abstract: A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply a negative pressure to the wound and a canister assembly. The canister assembly includes a control unit having a vacuum source and a controller and a collection canister in communication with the dressing assembly operable to receive fluid from the wound. The collection canister has a filter assembly having a filter and a passageway between the filter and a wall of the collection canister. The collection canister also includes a canister interface having a suction port, an inlet port, and a channel. The vacuum source draws air through the suction port from the channel which draws air from the passageway connected to the channel, the air in the passageway is drawn from the collection canister through the filter, and the air in the collection canister is drawn through the inlet port.

  • Publication number: 20230103651
    Abstract: A wound dressing for use in a vacuum wound therapy treatment includes a backing layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member affixed to the backing layer provides a connection to a reduced pressure source through an opening in an ambient surface. A primary port extends between the opening and a primary aperture in a reservoir surface to providing fluid communication between the reservoir and the reduced pressure source. At least one supplemental port establishes fluid communication between the primary port and a supplemental aperture in the reservoir surface that is distinct and substantially spaced from the primary aperture.

  • Publication number: 20210146024
    Abstract: A system for subatmospheric pressure therapy in connection with healing a wound is provided. The system includes a wound dressing cover dimensioned for positioning relative to a wound bed of a subject to establish a reservoir over the wound bed in which subatmospheric pressure may be maintained, a subatmospheric pressure mechanism including, a housing, a vacuum source disposed in the housing, and a collection canister in fluid communication with the vacuum source. The system further includes an exudate conduit in fluid communication with the wound dressing and the collection canister for collecting exudate removed from the reservoir and deposited in the collection canister under influence of the vacuum source and a vent conduit in fluid communication with the collection canister and the wound dressing for introducing air into the reservoir to facilitate flow of exudate through the exudate conduit.

  • Patent number: 10561793
    Abstract: The disclosed embodiment relates to an injection device that is a single patient use, disposable device containing a needle and a cartridge containing a drug, pharmaceutical product or other injectable agent. The device is initially provided in a pre-armed state in a first engagement configuration wherein the needle is separated from the septum of a cartridge. To arm the injection device, the professional urges the device from the first engagement or pre-armed configuration to a second engagement or armed configuration wherein the needle pierces the septum and provides a sterile fluid path to the drug, pharmaceutical product or other injectable agent contained within the cartridge. The disclosed embodiment is particularly adaptable to dental anesthetic applications, as well as other medical and veterinary applications.
