Abstract: A nebulizer to deliver a medicament that includes a housing having a reservoir for the medicament, an aerosol generator that can be supplied the medicament from the reservoir, where the generator aerosolizes at least a portion of the medicament into an aerosol, a gas venting inlet to permit a gas to enter the nebulizer and form a mixture with the aerosol, and a passage through which the mixture of the aerosol and the gas is delivered to an outlet port of the nebulizer.

Abstract: A nebulizing device for providing a nebulized fluid to a patient is provided. The nebulizing device may include a nebulizing element, a fluid delivery system, and at least one tube section. The fluid delivery system may be adapted to supply fluid to the nebulizing element. The at least one tube section may define a delivery path to the patient. The delivery path may be defined by a distance between the nebulizing element and the patient. The delivery path may have a length of less than about 500 mm.

Abstract: An apparatus for delivery of a medicament to the respiratory system comprises a reservoir that is adapted to hold a liquid medicament that is to be delivered to a respiratory system. An aerosol generator is provided that is adapted to aerosolize the liquid medicament. A liquid supplier is used to deliver the liquid medicament from the reservoir to the aerosol generator. A connector is operably coupled to the aerosol generator and comprises a gas conduit having an inlet, and an outlet, and an aerosol supply conduit. The aerosol generator is configured to provide the aerosolized liquid medicament into the gas conduit through the aerosol supply conduit, and the gas conduit is adapted to pass gases to entrain the aerosolized liquid medicament.

Abstract: A wheelchair cart configured for rollable transportation while carrying medical gas or other equipment is provided having a linkage assembly operable for linking the cart with a wheelchair while allowing the wheelchair/cart assembly to pass over uneven surfaces. The cart allows a single person to connect the cart to a wheelchair and transport the two simultaneously. The cart is configured such that equipment that should be transported with the patient and is often physically connected to the patient (e.g. ventilators, IV's, and monitors) is stored and transported on the cart. Risks associated with disconnecting the patient from vital medical equipment are minimized by eliminating the typical separate transportation of an equipment cart and a wheelchair by more than one person, which may result in a stretching or breaking of the attachment lines between the patient and the equipment.

Abstract: A piston based ventilator for delivering breathing gas to the lungs of a patient, and more particularly a piston based ventilator that delivers breathing gas to a patient upon longitudinal movement of a piston rod and associated piston head within a piston cylinder. The piston rod is centrally located within the cylinder and moves along the cylinder in response to direct drive from a motor to move the piston head within the cylinder and displace a volume of gas to be delivered to the patient.

Abstract: The piston ventilators include a double acting reciprocating piston, in which the piston motion delivering breathing gas to a patient receiving assistance from the ventilator simultaneously draws in breathing gas from a source of breathing gas, and a single acting piston ventilator, in which only the delivery end of the cylinder is provided with inlet and exhaust valves. In the double acting piston ventilator, breathing gas is supplied to both ends of the piston cylinder through two intake valves, and exhausting breathing gas through two exhaust valves. Both intake valves of the cylinder are ducted to the breathing gas supply, and the two exhaust valves of the cylinder are ducted to a gas delivery limb of the ventilator connected to the patient's airway.

Abstract: The ventilator airway fluid collection system permits the maintenance of PEEP in a patient breathing circuit when a fluid collector vial is removed. A fluid collection vial is connected to the airway from which fluid is to be collected by connection to an arm of a tee connector, and a disc assembly is provided in the arm of the tee connector that closes the opening to the vial when the vial is removed. The disc assembly includes a first disc fixedly mounted in the connector arm, and a second disc rotatably mounted to the first disc. The first disc includes at least one aperture, and the second disc includes at least one corresponding aperture. The second, rotatable disc includes at least one tab for indexing the second disc's aperture to open the passageway to the vial when the vial is attached, and to close the passageway when the vial is removed.
