  • Mechanism for measuring device
    Patent number: 6234972
    Abstract: A gage mechanism for a blood pressure measuring device or other similar apparatus includes a supported shaft member having one end in contact with an inflatable bellows. A pointer is attached at an opposite end of the shaft and a helically wound spring is attached to the shaft and a supporting structure. As the bellows inflates, the shaft is axially displaced and causes rotation due to the constraint of the helical ribbon spring, causing a corresponding angular deflection of the attached pointer relative to an indicating scale. The mechanism includes a first adjustment member for allowing the pointer to be preset to a zero or calibrated position, and a second adjustment mechanism that controls the amount of angular rotation of the shaft and pointer for a displacement of the bellows.
    Type: Grant
    Filed: September 21, 1999
    Date of Patent: May 22, 2001
    Assignee: Welch Allyn, Inc.
