  • Pneumatic oxygen conserving device
    Patent number: 7089938
    Abstract: A pneumatic oxygen conserving device uses a portion of gas exiting its main valve to interrupt delivery of the gas. Gas is dispensed upon inhalation and is interrupted by means of suitable pneumatic connections between the device's delivery system and its sensing system.
    Type: Grant
    Filed: February 2, 2004
    Date of Patent: August 15, 2006
    Assignee: Precision Medical, Inc.

  • Pneumatic oxygen conserving device
    Patent number: 6752152
    Abstract: A pneumatic oxygen conserving device includes a reservoir of pressurized gas delivered upon inhalation through a single-lumen cannula. Gas flow is interrupted by a series of interconnected passages and chambers, including a check valve which is acted upon by the flow of gas being delivered through the delivery outlet of the device. The device is self regulating to the extent that oxygen pulses of appropriate volume are delivered irrespective of the breathing rate of the user. The device includes a plate with various passages and chambers defined therein in such a way as to reduce the overall length of the device.
