Reservoir system for gas delivery to a patient

摘要

A breathing system is provided that employs a reservoir for holding oxygen or an oxygen and medicine mixture while the patient is not inhaling. The reservoir generally prevents waste and reduces cost and helps prevent the patient from re-inhaling the previously exhaled gases. The reservoir also may include a flange extending from an inlet thereof that allows the reservoir to be positioned in an inverted position.

主权项

1. A reservoir for a breathing system, comprising:
a body; a tube extending therefrom, said tube having a first end interconnected to said body and a second end; and a flange extending from said second end; wherein said reservoir is interconnected to a conduit that leads to an exhalation port of a patient mouth piece; and wherein said conduit includes a one-way check valve positioned that creates resistance to gas flow between said reservoir and said exhalation port that is greater than resistance associated with filling said reservoir with gas, said check valve associated with a valve seat that is angled with respect to a longitudinal axis of said conduit.
