Abstract

A single-patient-use disposable carbon dioxide absorbing and air treatment device is disclosed. Principal to the invention is an air impervious container having at least two openings for fluid communication between the inside and outside of the container. The container is also in fluid communication with a system for providing air to a patient by means of an airstream through a recirculating aided respiratory system. The container includes granular, carbon dioxide absorbing material, and may also include a bacteria filter. The airstream enters the container through the inlet opening and is dispersed into the granular material, where it is heated, humidified, and at least a portion of the carbon dioxide in the airstream is absorbed. The size and shape of the container and the amount of absorbent material are all preselected to provide for an immediate and optimal heating and humidifying effect and carbon dioxide removal. The airstream then exits from the outlet opening and is delivered to the patient without contacting regulator valves, pumps and the like, thereby avoiding heat loss and condensing of water vapor before the treated air reaches the patient. The construction is of sturdy, lightweight materials and the design is simple and straightforward, thereby minimizing the effort and training which would normally be associated with use of such a device.
