ABSTRACT:
An isolation valve for the resuscitation of patients which has an upper housing and a lower housing that snap together, rotate with respect to one another, and utilize a flexible diaphragm which extends into the small space between the upper housing and the lower housing to assure the establishment of an air-tight seal between the upper housing and the lower housing. The upper housing begins with an upper tube that expands outward to create an upper chamber segment. The lower housing has a lower chamber segment, the wall of which lower chamber segment establishing the snap-fit with the wall of the upper chamber segment. The lower chamber segment is formed by the outward expansion of a lower tube. Breath exhaled by a care provider proceeds along the upper tube to the upper chamber segment where it must pass through an upper filter segment, a lower filter segment, and a space between the two that provides a volume to retain any moisture which evades the filter segments. The exhaled breath from the care provider then passes through a check valve that precludes exhaled breath from the patient from traveling to the care provider and then into the lower tube. Breath exhaled by the patient is exhausted to the atmosphere through one or more apertures in the bottom of the lower chamber segment after having passed through an exhalation filter.
