Claim 3
Dependent Claim
158 words
IN POSITIVE PRESSURE BREATHING THERAPY WHERE A PRIMARY AIR FLOW IS SUPPLIED TO A PATIENT THROUGH AN INSPIRATOR BREATHING TUBE AND A SECONDARY, LESSER AIR FLOW CARRYING A NEBULIZED MEDICATION IS DISCHARGED INTO THE INSPIRATOR BREATHING TUBE ADJACENT TO ITS EXIT TO INTERBLEND WITH THE PRIMARY FLOW DURING AN INSPIRATION CYCLE OF BREATHING, A SEQUENCE ADAPTED TO PROVIDE A PATIENT WITH CONCENTRATED MEDICATION AT THE BEGINNING OF AN INSPIRATION CYCLE AND A MORE DILUTED MEDICATION IN THE LATTER PHASE OF THE INSPIRATION CYCLE, INCLUDING THE STEPS OF CLOSING THE INSPIRATOR BREATHING TUBE AT ITS EXIT DURING AN EXPIRATION CYCLE OF BREATHING, STOPPING AND REVERSING THE PRIMARY FLOW IN THE INSPIRATOR BREATHER TUBE AND FILLING THE PORTION OF THE INSPIRATOR BREATHING TUBE ADJACENT TO ITS EXIT WITH SAID SECONDARY AIR FLOW AS THE PRIMARY FLOW IS REVERSED WHEREBY TO PERMIT THE INHALATION OF AN UNBLENDED MEDICAMENT CARRYING SECONDARY FLOW AT THE BEGINNING OF THE FOLLOWING INSPIRATION CYCLE OF BREATHING.
