  • Publication number: 20100024818
    Abstract: A respiratory apparatus including an adapter assembly and a catheter assembly. The adapter assembly includes ventilator, respiratory, access, and flush ports. The access port includes a conduit defining a passageway. The flush port projects from the conduit and is fluidly open to the passageway at an outlet. The catheter assembly includes a catheter assembled to a fitting. The fitting includes a hub and a tube, with the tube defining an exterior surface, an interior surface forming a lumen, a circumferential groove in the exterior surface, and a plurality of apertures fluidly open to the lumen and the circumferential groove. The tube is sized to be slidably received within the passageway such that upon final assembly, a fluid pathway is formed between the flush port and a distal end of the catheter via the flush port outlet, the circumferential groove, the plurality of apertures, and the lumen.

  • Patent number: 7509957
    Abstract: A pressure driver for a ventilation system comprises a gas source, an inspiration flow control valve and a patient pressure sensor to form a closed loop control system. The inspiration flow control valve may be mounted within a housing and is operative to open and close in response to patient pressure measurements in order to produce a desired pressure at the patient. The pressure driver may further include a mixture control for allowing selective adjustment of the oxygen concentration in pressurized gas delivered to the patient. An oxygen mixer is connected between the gas source and the mixture control and is operative to deliver the desired mixture of oxygen and air to the inspiration flow control valve for delivery to the patient. An oxygen sensor monitors the oxygen concentration in the gas provided by the oxygen mixer.

  • Publication number: 20080295846
    Abstract: An integrated nasal mask is adapted for delivering gas to a patient and comprises a mask body and a pair of elongate nostril-engaging stems. The mask body is generally triangularly shaped and includes a nasal opening sized and configured to substantially envelope a patient's nose. The nasal opening opens to a nasal cavity. The nostril-engaging stems extend outwardly from the nasal cavity. Each one of the stems defines a fluid passageway for delivering gas to the patient's nose and for allowing discharge of exhalation gasses during the exhalation phase of the breathing cycle.

  • Patent number: 7303153
    Abstract: A spray head provided with a plurality of nozzles defined by a base and a deflector cap. Each nozzle is provided with a deflector portion or nozzle plate for directing an upward traveling fluid in an outward direction. Furthermore, the deflector portion may be provided with steps or vanes for altering and varying the flow characteristics of a fluid spray pattern exiting the nozzle. In this manner, different portions of the fluid spray pattern may be projected to varying distances so that the fluid may cover an area having generally straight boundaries and having one or more right angles. Furthermore, the fluid spray pattern may be used to cover a triangular area. In this manner, overspray is reduced. The areas covered by independent nozzles of the spray head may be proximally located by their arrangement within the spray head so as to minimize overlap of the areas.

  • Publication number: 20070101999
    Abstract: Provided is a high frequency oscillating ventilator comprising a housing assembly, a linear actuator, a linear coil, a piston mounted on a pushrod, a diaphragm dividing a housing into a first and second side and having an opening formed on the second side that is fluidly connected to the patient's airway for delivering gas thereto. The linear actuator is fixedly mounted to the housing assembly and has a linear coil coaxially disposed therewithin. A pushrod supports the linear coil on the linear actuator to allow relative axially sliding therebetween. The piston is directly mounted to the diaphragm such that reciprocation thereof as effectuated by the linear coil cooperating with the linear actuator alternately produces positive and negative pressure waves in the gas in the patient's airway.

  • Patent number: 6932603
    Abstract: An interproximal squirt brush includes a squeezable bottle having a solution cavity for containing a washing solution and a nozzle head having an opening, and a brush head including a brush arm and a brush member. The brush arm has a brush portion and a resilient portion slidably inserted into the opening of the squeezable bottle for providing an urging force against an inner wall of the nozzle head, wherein a dispensing channel is formed between the resilient portion of the brush arm and the inner wall of the nozzle head for allowing the washing solution to pass therethrough. The brush member is provided at the brush portion of the brush arm. Therefore, when a squeezing force is applied on the squeezable bottle, the washing solution is released to the brush member through the dispensing channel of the nozzle head.
