Publication number: 20240009372Abstract: 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.Type: ApplicationFiled: June 30, 2023Publication date: January 11, 2024Inventors: Richard M. Braga, David E. Fink, David Heagle, Arnaz S. Malhi, David R. Swisher, Scott Wudyka

Publication number: 20230103651Abstract: 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.Type: ApplicationFiled: August 31, 2022Publication date: April 6, 2023Inventors: Julia-Rose Anderson, Richard M. Braga, Deirdre McKeown, Adam M. Ruggles, Chirag B. Shah, David R. Swisher, Mark A. Vess, Ronald F. Vitaris

Patent number: 10561793Abstract: 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.Type: GrantFiled: September 9, 2014Date of Patent: February 18, 2020Assignee: KPR U.S., LLCInventors: Melvin A.
