Alveolar breath volumetric analysis for alcohol

Abstract

Abstract A BREATH SAMPLING KIT AND METHOD FOR SAMPLING BREATH ARE DESCRIBED FOR SAMPLING THE QUANTITY OF ALCOHOL IN A FIXED QUANTITY OF BREATH WITHOUT ELEBORATE APPARATUS. ACCORDING TO THIS ARRANGEMENT, A TEST SUBJECT INFLATES AN INELASTIC BAG OF PREDETERMINED VOLUME CONNECTED IN BYPASSING RELATION TO AN ELASTIC CONTAINER SUCH AS A BALLOON. THE VOLUME OF THE BAG IS SUCH AS TO ACCOMODATE THE NONALVEOLAR BREATH OF THE TEAST SUBJECT. AFTER THE BAG IS FILLED, THE BALLOON IS INFLATED WITH THE ALVEOLAR BREATH. THE BALLOON IS THEN DEFLATED THROUGH A SAMPLE TUBE IN WHICH A SOLID MATERIAL IS CONTAINED AND INFLATES A SECOND INELASTIC BAG, THE VOLUME OF WHICH BEARS A FIXED RELATION TO 1 MILLITIER OF BLOOD SO THAT UPON SUBSEQUENT ANALYSIS THE QUANTITY OF ALCOHOL IN THE BLOOD IS DETERMINED DIRECTLY. THE SOLID MATERIAL IN THE TUBE ADSORBS ALCOHOL IN THE BREATH AND KEEPS IT TRAPPED FOR LATER EXTRACTION AND ANALYSIS. THE ALCOHOL IS EXTRACTED FROM THE SOLID BY WATER OF OTHER SOLVENT FOR ALCOHOL PASSED THROUGH THE SOLID, AND THE SOLID MATERIAL IS SELECTED FROM REVERSIBLY ADSORBING THE ALCOHOL AND BEING SUBSTANTIALLY INSOLUBLE IN THE EXTRACTING SOLVENT SO AS NOT TO INTERFERE WITH SUBSEQUENT ANALYSIS, SILICA GEL BEING PARTICULARLY PREFERRED.
