First Claim
1. A breath flow meter comprising a hollow meter body;
- flow measurement means mounted in said body for measuring and displaying the flow rate of breath passing through said meter body;
a mouthpiece at a first end of said body and a breath outlet in said body displaced from said first end;
a cover coacting pivot means for pivotally mounting said cover to said body, and means for selectively maintaining said cover in a chosen one of two alternative orientations wherein a first orientation encloses said mouthpiece and a second orientation extends said cover from said body as a handle.

Abstract
A portable peak flow meter for monitoring the expiratory flow rate of a user includes an on-line metering unit having a combination cover and handle. The metering unit, which has opposed mouthpiece and exit ends, is of generally rectangular construction. A pair of opposed and hinged cover elements are pivotly mounted to the side walls of the metering unit, and pivot from a first position in which they embrace and cover the mouthpiece, to a second position perpendicular to the length of the metering unit in which they serve as a handle. The cover elements both maintain the mouthpiece in a sanitary condition when the unit is not in use and allows the unit to be held in a manner where the user'"'"'s hand is distanced from the meter, thus preventing interference with operation of the unit.
