Disposable breath analyzer.

摘要

A portable, pocket-size, disposable breath analyzer device (10) is disclosed characterized by a tubular housing (12) having an end portion (14) formed to be placed in the mouth of a user and a central portion carrying a canister (24) filled with a quantity of potassium di-chromate impregnated silica gel (30) adapted to provide a visual color indication of the amount of alcohol contained in a user's breath sample blown through the housing. A pair of valve members (40) are positioned on opposite sides of the canister within the housing to prevent any back aspiration of air to the user from the canister (24). Three embodiments of the invention are disclosed, each adapted to yield a visual indication of the approximate blood alcohol level of an individual user.
