Assignee:
Regents of the University of Minnesota - St. Paul MN
International Classification:
A61B 510
US Classification:
128774
Abstract:
A pressure algometer apparatus (20,50). The pressure algometer apparatus (20) provides an all mechanical pressure algometer including a balloon-like bladder member (22) for positioning at an end of a user's finger. An air tight interior (44) of the balloon-like member (22) is interconnected by tubing (42) to a pressure gauge (40). The algometer apparatus (50) includes a handheld pressure transducer (52) electrically interconnected (53) to an amplifier meter arrangement (54).

Abstract:
A pressure algometer apparatus (50, 100) is provided. The pressure algometer apparatus (50, 100) provides a combination mechanical and electrical pressure algometer including a hand held pressure transducer (52, 102) electrically interconnected (53, 138) to an amplifier meter arrangement (54, 104). The algometer apparatus (50, 100) includes a pressure readout display (70, 144) which indicates the pressure sensed by the pressure transducer (52, 102). A recording device (150) may be attached to the algometer apparatus (100) to provide a permanent record (148) of the pressure sensed by the pressure transducer (102). The pressure algometer apparatus (100) further includes a latch device (106) which, when activated, holds the pressure readout display (144) constant and marks the permanent record (148).
