Actuation of the input device may include application of a force downward toward the base. The water flosser may include a motor having a dual output shaft, with one end of the shaft being associated with a rotary encoder or other sensing device to determine an operational characteristic of the motor. The motor may be driven by a power source such as a rechargeable battery.

Abstract: In one aspect of the present invention, there is provided a modular respirator comprising an elongate filter unit having a filter inlet, a filter a filter outlet, and a replaceable fluid filter for filtering pollutants within the fluid. The elongate exhaust unit having an exhaust inlet, an exhaust outlet, and one or more one-way valves. A mask assembly having a mask for covering the oral and nasal passage of a user, a mask inlet at one end of the mask, a mask outlet at an opposite end of the mask, wherein the mask inlet is releasably fastened to the filter outlet, and the mask outlet is releasably fastened to the exhaust inlet.

Abstract: Embodiments relate to a single-use device for delivery of medication into a nasal cavity. In an embodiment, the device includes a propellant canister containing a propellant capable of propelling the compound to the nasal cavity. The propellant canister is displaceable between an unactuated position and an actuated position within the device. The device further includes an actuation element with an actuation lever configured to displace the propellant canister from the unactuated position to the actuated position. The device also includes a puncture element positioned to puncture the propellant canister, which causes the release of the propellant from the propellant canister. The device further includes a dose holding chamber containing a unit dose of the compound. The dose holding chamber is positioned such that propellant flows into the dose holding chamber and causes the compound to be propelled from the dose holding chamber to the nasal cavity of the user.

Abstract: An apparatus for generating and providing a pressurized breathable gas to a patient's airways includes a respiratory pressure therapy (RPT) device having an engagement port pneumatically and electrically coupled to the RPT device, and an air delivery tube configured to engage the engagement port so as to pass a flow of breathable gas to a patient interface. The air delivery tube includes electric contacts associated with a heating and/or a sensing arrangement. The air delivery tube includes a locking collar rotatably movable between (1) an unlocked position to allow connection/disconnection of the air delivery tube to/from the engagement port, and (2) a locked position to releasably lock the air delivery tube to the engagement port. The air delivery tube is structured and arranged to, when the locking collar is rotated into the locked position, pneumatically connect to the engagement port and define an operational configuration of the apparatus.

Abstract: Systems and methods for isolating and/or desiccating a portion of a drug delivery tract of a drug delivery apparatus to reduce water vapor content therein are provided. For example, there is provided a metered dose inhaler for delivering aerosolized medicament or other matter to a user. The aerosolized medicament or other matter may be discharged from a discharge passageway within the inhaler into an inhalation passageway for inhalation by a user, and the inhaler may comprise a seal member operative to selectively isolate the discharge passageway from the inhalation passageway and external environment during inactivity. The inhaler may further comprise a desiccant material arranged to withdraw moisture from the isolated discharge passageway. In other instances, desiccant material may be arranged to withdraw moisture from the discharge passageway of the inhaler without isolating the discharge passage during inactivity.

Abstract: A T-piece for controlling ventilation support to a patient includes a t-shaped body having a gas source connection port, an interface connection port, and a positive end-expiratory pressure (PEEP) control port. A PEEP adjuster cap is connected to the PEEP control port and has a bypass hole to allow gas to exit the T-piece and configured such that when the bypass hole is closed substantially all gas received at the gas source connection port is directed to the patient and when the bypass hole is open at least a portion of the gas received at the gas source connection port exits through the bypass hole to maintain PEEP to the patient. A bypass cover is automatically operated by an actuator circuit to close the bypass hole to enable delivery PIP to the patient and to open the bypass hole to effectuate PEEP delivery to the patient.
