Abstract: A vial adapter is provided with a fitting portion which can be fitted into the head portion of a vial, and a hollow needle with a side hole. The base end portion of the needle is provided with a stopper contact portion which contacts the top surface of a stopper when the fitting portion is fitted in the head portion of the vial. When the fitting portion is fitted in the head portion of the vial, the stopper contact portion contacts the top surface of the stopper, and the fitting portion is fixed to the head portion of the vial by a claw engaging with the head portion of the vial, and further, the region of the side hole nearest the base end portion of the needle is positioned either roughly at the bottom surface of the stopper or inside of the stopper.

Abstract: An aerosol generator device comprises an elongate body with an interior passageway extending longitudinally to its mouth end. The device receives an interchangeable, pressurized canister charged with a nicotine containing liquid that is discharged in a metered dose on manual actuation of a trigger that causes a valve in the canister to open and discharge through a discharge tube. Inner and outer collar members releasably couple the canister with a bayonet action. The trigger is rotatably mounted on the body about a trigger axis spaced from and extending transversely of the longitudinal axis of the device, and has a manually depressible surface portion under a flexible cover, and a camming surface portion that drives a slidable nozzle member inwardly of the body to press the discharge tube inwardly of the canister and the valve so as to form an aerosol from the liquid released from the canister.

Abstract: A rebreathing apparatus has a clothing article wearable on a person. The clothing article defines a channel configured to be fluidly connected to at least one tube. The tube is configured to be fluidly connected to a mouthpiece. When the person exhales, the exhaled breath enters one end of the channel and passes through the channel while being scrubbed of CO2. When the user inhales, the scrubbed air is drawn from the channel.

Abstract: A breathing apparatus including a face piece for covering the whole face or part of the face, an inhale valve and an exhale valve provided on the face piece, a motor fan for supplying external air into the face piece through the inhale valve, a filter for cleaning the external air sucked into the motor fan, a breath monitoring apparatus provided on the face piece and not comprising the inhale valve and the exhale valve, and a controller for controlling the operation of the motor fan synchronously with the breath based on the detection signal from the breath monitoring apparatus.

Abstract: A respiratory valve apparatus with a housing having an inner chamber, an endotracheal tube connection port, a respirator connection port and a resuscitation bag connection port. A valve positioned within the inner chamber can switch the flow between a manual resuscitation bag port and a ventilator port enabling the patient to be treated without having to disconnect the respirator support system to thereby connect the resuscitation bag. This prevents the loss of positive end expiratory pressure (PEEP) in the lungs and guards against lung collapse and hemodynamic compromise. The valve includes preloaded seals that will create minimal dragging during valve actuation and work under both positive and negative pressure. The apparatus includes a tethered cover for closure of the resuscitation bag port for sealably covering the port when a bag is not attached or the ventilator connector during patient transport.

Abstract: A fluid dispenser device comprising: a body (10); at least one individual reservoir (21); movable support means (50) that receive at least one reservoir (21), and that are displaceable between a non-dispensing position and a dispensing position; reservoir-opening means (80) for opening a reservoir when said opening means are actuated; loading means (800) for urging said movable support means towards said dispensing position; blocking means (100) for retaining said movable support means in the non-dispensing position; and inhalation trigger means (60); said blocking means (100) comprising a blocking element (110) that is movable between a blocking position and an unblocking position, said blocking element (110) co-operating with a projection (501) that is secured to movable support means (50).

Abstract: A patient interface system (30) that includes a patient interface assembly (40) and a headgear assembly (70). The patient interface assembly (40) includes a frame (42), a patient circuit connector (44), a seal member (46), and a coupling assembly (50) extending from the frame. The coupling assembly (50) is directed toward the users forehead when worn. The headgear assembly (70) includes an elongated pad support (72), a headgear attachment element (78) disposed on the pad support (72), a headgear strap (80) coupled to the headgear attachment element (78), and an elongated headgear pad (74) coupled to the pad support (72). The pad support, pad, or both are configured so as to extend from the forehead of the user generally along a centerline of the head and terminate proximate to a top of a head. In addition, a coupling assembly attachment assembly (100) is operatively coupled to the pad support (72) to couple the coupling assembly (50) of the patient interface device to the headgear assembly (70).
