  • Patent number: 6802314
    Abstract: A flow probe for use in a humidification system is disclosed. The flow probe is adapted to be positioned in a humidified gases flow (for example oxygen or anaesthetic gases) such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors (preferably thermistors) and the shape and alignment of the probe enables accurate readings by reducing the occurrence of condensation on the sensors.

  • Patent number: 6748945
    Abstract: An apparatus and method for providing a nebula or aerosol to a patient. In one aspect, a nebulizer is pressure sensitive so that nebulization is coordinated with a breathing cycle of the patient. The nebulizer includes a movable gas diverter that diverts pressurized gas across a liquid outlet. The diverter is moved in response to the patient's breathing cycle. In one aspect, a biasing member moves the diverter. According to another aspect of the nebulizer, an annular liquid orifice disperses an aerosol in a radial direction in response to a pressurized gas flow from an orifice located concentrically thereto. Multiple liquid orifices may be provided. In a further aspect of the nebulizer, a reservoir includes an upper, wide portion and a lower narrow portion to apply relatively uniform pressure at a liquid orifice.

  • Patent number: 6745763
    Abstract: In existing vaporizers the medication passes through unsterilized passages which preclude heir use to administer sterile medications. The present invention therefore provides a device for dispensing a vaporized spray of sterile medicated liquid. It uses a combination atomizing and pressure release valve in which there is a flexible membrane with an aperture, and a plug extending upwardly through the aperture and having a surface against which the membrane is biassed in the closed position, the membrane lifting off the surface of the plug in the open position to thereby open the aperture.

  • Patent number: 6729333
    Abstract: A low contact nasal mask assembly that includes a seal member defined from a unitary piece of elastomeric material. The seal member defines a nose receiving cavity and has a first end portion and a second end portion generally opposite the first end portion. A first open is defined in the first end portion to allow at least a portion of a nose of a patient to enter the nose receiving cavity such that the nares of the patient communicate with the nose receiving cavity. The seal member also includes a neck portion defined in the second end portion and a second opening defined in the neck portion in communication with the nose receiving cavity. In addition, an outside diameter of the seal member and an inside diameter of the seal member increase generally linearly from the second end portion to the first end portion to minimize contact of the seal member with a patient and to minimize dead space.
