Peak flow measuring device

A device for measuring a urine discharge, comprising:

• a hollow receptacle having sidewalls at least partially defining a chamber, a lower wall having an aperture communicating between the chamber and atmosphere, an inlet port adjacent an upper end of the receptacle and communicating with the chamber to receive the discharge for passage into the chamber, and an outlet port adjacent a lower end of the receptacle and communicating with the chamber for passage of the discharge at a predetermined rate out of the chamber;
• a collection container having a closed bottom, an elongated generally tubular section defining a collection cavity in the container, and an opening adjacent an upper end of the container communicating with said cavity, said container being removably received in the receptacle aperture with the container opening spaced a predetermined distance above the lower receptacle wall in said chamber, and with the receptacle sealingly engaging against a surface of the container in the region of said aperture, such that the discharge passes from the receptacle chamber through the container opening into said cavity at a predetermined height of the liquid in said chamber to provide a discrete indication of the discharge peak flow rate and a specimen of the discharge in said cavity for analysis upon removal of the container from the receptacle.
