  • Pneumotach and components therefor
    Patent number: 4995400
    Abstract: A pneumotach is provided that is effective for obtaining accurate flow measurements through a wide range of velocities by measuring substantially linear flow, and which includes a readily disposable element. The pneumotach also includes a holder adapted for readily holding the disposable element in a manner so as to be substantially free of patient contamination, and with transducer capability for detecting pressure and measuring the same at low flow rates. A combined pulmonary functioning measuring kit includes computer and read-out capabilities for selectively receiving input from either spirometer or the pneumotach. The kit is readily assembled and is self-contained.
    Type: Grant
    Filed: January 27, 1989
    Date of Patent: February 26, 1991
    Assignee: Boehringer Laboratories
    Inventors: John R. Boehringer, Jay B. Nelson, John Karpowicz
