Portable emergency respiratory system

Claim 1

An emergency respiratory system for administering oxygen therapy and treating an individual in respiratory failure, comprising: an endotracheal adaptor unit having a fluid passage; an endotracheal tube attached to said adaptor unit and communicating with said fluid passage, said endotracheal tube insertable within the windpipe, trachea, or esophageal airway of an individual undergoing treatment; pressurized oxygen delivery means attached to said adaptor unit and communicating with said fluid passage for introducing relatively high pressure oxygen into said fluid passage; and pressure-applying and directing means attached to said adaptor unit and communicating with and providing a continuation of said fluid passage away from that of said endotracheal tube, said last-named means including a single flexible tubing having one end attached to said adaptor unit and the other end opening to the atmosphere, said flexible tubing being manually squeezable to a first, compressed position to shut off the flow of pressurized oxygen through the continuation of said fluid passage formed by said flexible tube and positively redirect the flow through said endotracheal tube to inflate the individual's lungs, and releasable to a second, tube-expanded condition to provide for the expiration of the lungs through the said flexible tubing.
