Identification of the Device
BACTRACK® Breathalyzer Digital Alcohol Detector: Breath-Alcohol Test System.
Indications for Use
This device is intended to measure alcohol in the human breath. Measurements obtained by this device are used as an aid in the detection of alcohol intoxication.
Description of Device
The BACTRACK is designed to measure deep lung air to test for the presence of alcohol in the blood. The relationship between alcohol in the blood and alcohol in the deep lung breath is well established by Henry’s Law in ratio of 2100:1.
The BACTRACK Breathalyzer has been tested and uses a blow time of of 5 seconds to capture an accurate deep lung sample. The BACTRACK Breathalyzer sensor uses tin dioxide which has n-type conductivity when exposed to the atmosphere. This exposure causes a decrease in the number of electrons effecting absorbed oxygen molecules and thus increases resistance.
If a specific gas (reducing gas) is presented, a reaction occurs with the absorbed oxygen which causes an increase in the electrons in the oxide molecules causing a decrease in resistance. This change in resistance can be measured and used to identify a specific gas (such as alcohol) and can be quantified into a % concentration.
Safety and Effectiveness
The results of bench, and user testing indicates that the new device is as safe and effective as the predicate device. A clinical trial was performed to establish that the user could read and understand the instructions provided, and properly use the device, as well as perform comparably to an evidentiary type of breath alcohol tester.
