  • 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: 20140296826
    Abstract: A safety syringe system including a safety syringe and an injection site preparation patch adapted for use with the safety syringe. The safety syringe includes a syringe body and a safety shield slidably disposed about the syringe body. The injection site preparation patch has a tissue-facing side and a syringe-facing side, and may include a substrate, a syringe adhesive layer adapted to adhere to a distal flange of the safety shield, a hydrogel layer adapted to adhere to tissue, and removable release liners disposed on either side. The patch may include a medicament, anesthetic, or a thermal compound. Adhesion between the patch and the flange is less than adhesion between the patch and tissue, so that the patch adheres to the shield with sufficient strength to enable the shield to slide over the needle upon withdrawal, but with insufficient strength to cause the patch to pull away from a patient's skin.
