Patent ID: 8210178

Claim:
A respirator comprising: a respirator housing with a rapid action coupling; a carbon dioxide absorber with absorbent and with a connection element, which is complementary to said rapid action coupling, said connection element being pivotably connected to said rapid action coupling such that said carbon dioxide absorber moves from a disconnected position to a connected position, said carbon dioxide absorber being in communication with said respirator housing in said connected position, said connection element engaging said rapid action coupling in said connected position, said carbon dioxide absorber not being in communication with said respirator housing in said disconnected position; a transponder at said carbon dioxide absorber; a memory chip associated with said transponder, said memory chip containing data on the type, period of use and current state of consumption of said absorbent, said memory chip being arranged at said carbon dioxide absorber; and a transponder polling device at said respirator housing, said transponder polling device having a polling transmission range, said transponder being within said polling transmission range with said carbon dioxide absorber in said connected position, said transponder being located outside of said polling transmission range with said carbon dioxide absorber in said disconnected position, said transponder polling device reading data from said memory chip and storing data obtained during operation again in said memory chip in the form of an updated state of consumption with said carbon dioxide absorber in said connected position.
