ABSTRACT:
An efficient, low cost, single-patient-use disposable carbon dioxide absorbing device which avoids use of any moving parts. A transparent flexible sac container having at least two openings for communication between the inside and outside of the container is described. The sac is included within a system for providing air to a patient by means of an airstream through a conduit. The sac includes granular, carbon dioxide absorbing material, an air inflow hose and an air outflow hose. The airstream enters the sac through the inflow hose and is dispersed into the granular material, which absorbs at least a major portion of the carbon dioxide in the airstream. The airstream then enters into the outflow hose and is provided to the patient, thus minimizing the deleterious effects of carbon dioxide in the breathing gas. The construction is of sturdy, lightweight materials minimize the effort and training which would normally be required for replacing a unit which has expended its carbon dioxide absorbing capability.
