Embodiment Construction

[0040] Gas masks are used to protect the human respiratory system in potentially harmful environments. Respirators are coverings that are placed over the wearer's mouth and nose to protect the user from inhalation of airborne toxic materials by absorbing or adsorbing airborne toxins on filters or chemical adsorbents before the air enters the user's respiratory system. The airborne toxin may be any potentially hazardous chemical compound such as, but not limited to, airborne chemical pollutants, particles, and / or toxic gases, for example. For example, the airborne toxic material may be gaseous, airborne, or particulate.

[0041] Respirators form a seal over the nose and mouth, so air must be drawn through a canister, cartridge, and / or filter (hereafter "canister") that includes sorbent material, filter media, or other respiratory protective material (hereinafter "canister") to the respirator and mouth. In the inner volume between the faces of the wearer. Canisters remove airb...

Abstract

Gas masks and canisters for gas masks have a chemical sorbent that protects the respiratory system of the wearer from gaseous compounds. The remaining service indication systems for respiratory protections systems provide a warning to the wearer that the capacity of the chemical sorbent to adsorb or absorb further compounds is nearly depleted. A remaining service life indication system has a computer memory device for storing information concerning the canister for determining an end of the service life of a gas mask, a canister and / or a cartridge and such devices from the input of various sensors.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 201180052526.9, the application date is September 7, 2011, and the invention title is "indicating the remaining service life of gas mask cylinders and tanks". [0002] Related patent applications [0003] This patent application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 61 / 380,604, filed September 7, 2010, which is hereby incorporated by reference in its entirety middle. technical field [0004] The invention relates to a respiratory protection system comprising a gas mask and a canister for the gas mask. Some embodiments include: a remaining useful life indicator or remaining useful life indicating system for a respiratory protection system; a respirator including a remaining useful life indicating system; and a canister including a computer memory device. Several embodiments further include methods of determinin...
