  • Patent number: 10953165
    Abstract: A dry powder inhaler (10) having a chamber (26) divided into first and second blister compartments (28, 30) for storing unused and used portions (34, 36) of a blister strip (12) is provided. A moveable dividing wall (32) separates the first and second blister compartments. One or more arcuate supporting surfaces (38, 40, 42) are disposed in either the first and/or the second blister compartments and these surfaces support the used or unused blister strip during successive actuations of the inhaler. Use of the arcuate supporting surfaces facilities compact coils of unused and used portions of blister strip, thereby reducing the size of the chamber required for the inhaler.

  • Patent number: 10946152
    Abstract: An anesthesia delivery and monitoring system for use during outpatient surgery performed under sedation level anesthesia that includes a ventilatory system, a system for supplying sedation anesthesia, a respiratory sensor adapted to detect a respiration parameter of such a patient, and a system for supplying a timed back-up breath to such a patient through the ventilatory system. The timed back-up breaths are supplied in response to the respiration parameter falling outside a preset threshold and at a positive pressure exceeding a base operating pressure of the respiratory system. The system for supplying sedation anesthesia is an intravenous supply system for anesthesia, a ventilatory system coupled to the patient, a needle and syringe, or any combination thereof. The respiratory system includes a PC-based physiologic monitor with user modified feedback control signal.

  • Patent number: 10926053
    Abstract: Described here are closed-circuit breathing devices and methods for their use. In general, the closed-circuit breathing device is configured to achieve a steady-state equilibrium, whereby therapeutic gas is introduced into the breathing circuit in small, controlled volumes until a steady state concentration of the therapeutic gas is reached. During this time, the closed-circuit breathing device is operated in a true closed circuit, such that the therapeutic gas is not lost to the atmosphere. Safety measures are built into the closed-circuit breathing device so that a hypoxic mixture is not delivered to the subject. The therapeutic gas may be xenon.

  • Patent number: 10869985
    Abstract: A flow member (200) is for a flow assembly (100) of a pressure support system (2). The pressure support system includes a patient interface device (6), a flow generator (4), and a coupling conduit (8). The flow assembly includes a cover (102) and a sensing assembly (110). The sensing assembly has a flow sensor (114) having flow sensing components (118,120). The flow member comprises: a body (202) comprising: a mounting portion (204) connected to the cover, thereby enclosing the sensing assembly, a gas conduit (206) at least partially overlaying the mounting portion, the second conduit fluidly coupling the first conduit to the flow generator, and a number of flow conduits (208,210) each extending transverse to the gas conduit (206) and receiving a corresponding flow sensing component.

  • Patent number: 10835704
    Abstract: A reusable respirator including a mask adapted for covering and conforming to the face around the nose and a mouth of a user, a strap configured to secure the mask to a face of the user, and a filter component. All components of the respirator are capable of being cleaned, disinfected and sterilized at temperatures in excess of 50° C. An outer surface of the mask is substantially smooth and wettable for easily disinfecting and is shaped with a pair of outer shield portions for housing particulate air filters. The outer shield portions each include a closeable vent through the outer surface that is adapted to provide a user seal check and direct air flow through the outer surface for filtering by the respective particulate air filter, which is adapted to filter at least 95% of airborne particles.

  • Patent number: 10828432
    Abstract: The present invention provides for a particulate delivery device capable of facilitating both respiratory delivery of compositions under negative pressure and positive pressure. The device comprises an actuator, movable by negative pressure or positive pressure, to allow for gas flow through the device and simultaneously assist with delivery of the particulate into a vortex chamber prior to delivery to the airway of a subject.
