Device for reducing the carbon dioxide concentration of inhaled air

摘要

Anxiety attacks can often be limited or eliminated by reducing the concentration of inhaled carbon dioxide. Disclosed is a handheld device for reducing the carbon dioxide concentration of inhaled air by using stacked sheets having rows of adsorbents deposited thereon and which form a removable cartridge. The cartridge is placed into an adsorbent cartridge cradle to secure the cartridge within the device housing and to maintain ventilation channels through the cartridge. Inhaled air passes through the adsorbent containing cartridge and exhaled air exits the device through a bypass to avoid poisoning the adsorbent with exhaled carbon dioxide.

主权项

1. A device for removing undesired constituents from air, said device comprising:
a housing, said housing having a ventilation port for insertion into the mouth through which air is inhaled from said housing and exhaled into said housing; an exhaust port in said housing through which exhaled air is expelled from the housing; an air inlet port in said housing through which inhaled air is drawn into and through said housing to said ventilation port along an inhalation channel which directs air from said air inlet port to said ventilation port through a series of walls and directional valves; an air treatment device arranged within said inhalation channel; at least one air inlet valve, said air inlet valve arranged to open upon inhalation to direct air flow through said air inlet port and along said inhalation channel to exit through said ventilation port and close upon exhalation through said ventilation port into said housing and along an exhalation channel so as to inhibit exhaled air from entering said air treatment chamber within said housing; at least one air outlet valve, said air outlet valve arranged to open upon exhalation to direct air flow entering said housing through said ventilation through said housing to exit through said exhaust port and close upon inhalation through said ventilation port into said housing so as to inhibit the introduction of air into said housing from said exhaust port; and a removable housing for aligning and positioning said air treatment device within said inhalation channel.
