The device description focuses on the physical and chemical principles of semiconductor oxide sensors for detecting alcohol, with no mention of AI or ML algorithms for data processing or interpretation.
No
The device is intended to measure alcohol in human breath for the diagnosis of alcohol intoxication, but it does not provide treatment or mitigation of a disease or condition.
Yes
The "Intended Use / Indications for Use" section explicitly states, "Measurements obtained by this device are used in the diagnosis of alcohol intoxication."
No
The device description clearly details hardware components like a semiconductor oxide sensor, ceramic catalytic filter, and mentions measuring resistance changes, indicating it is a physical device with integrated software, not a software-only medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The AlcoMate measures alcohol in breath, which is a sample taken from the body, but the measurement is performed ex vivo (outside the living organism) and the analysis is based on the chemical properties of the breath sample itself, not on a biological reaction or analysis of a biological component within the sample.
- Intended Use: While the intended use mentions "diagnosis of alcohol intoxication," the mechanism of action is a direct measurement of a chemical substance in breath, not an analysis of biological markers or reactions within a biological sample.
Therefore, while it's a diagnostic tool, it falls under the category of a breath alcohol measuring device rather than an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The device is intended to measure alcohol in the human breath. Measurements obtained by this device are used in the diagnosis of alcohol intoxication.

Device Description
The AlcoMate 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 AlcoMate is a D.O.T. approved alcohol screening device and uses a blow time of 5 seconds to capture an accurate deep lung sample. The AlcoMate contains a semiconductor oxide sensor designed to test for the presence of alcohol. The AlcoMate semiconductor contains a recently developed ceramic catalytic filter which greatly increases the sensors specificity to alcohol . The AlcoMate sensor uses oxide 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.

Part names
Image /page/2/Figure/5 description: This image shows a diagram of a breathalyzer and instructions for its preparation. The diagram labels parts such as the "breath pipe", "display window" which reads "0.05", "ready lamp", and "battery low lamp". The instructions indicate that a 9 Volt Battery should be installed.
- The tester comes with one plastic mouthpiece already over the breath pipe. You may wish to replace the mouthpiece for 2. use by another person for sanitary reasons. To change mouthpieces, align the slot in the mouthpiece with the slot on the breath pipe.
Operation: Read these instructions before consuming alcohol.
- WAIT! 20 minutes after drinking alcohol before taking a reading. If you don't wait, the reading will measure alcohol in the mouth, which does not accurately show your blood alcohol level.
-
- Press the ON/OFF Power switch. WAIT! The detector will start to countdown from 200 to 000 on the display window. This warm up process prepares the sensor and circuit for testing. When you hear a BEEP and the green READY light comes on, go to step 2.
-
- Take a deep breath, then blow steadily and continuously (at least 5 seconds) into the pipe until you hear another BEEP. Your lips should be sealed around the mouthpiece while blowing. Be careful not to cover the Breath out opening on the unit. (If you don't blow within 30 seconds, the unit automatically displays "OFF" and will turn off.) After the red and green display lights blink for 4 seconds, the test result will be displayed for 15 seconds. This is your Blood Alcohol Concentration, or BAC. Finally, the unit shows "OFF" for turn-off, along the BEEP sound. Press the ON/Off power switch to turn unit off.

Understanding the Results
For many years, the legal standard for drunkenness across the United States was 0.10, but many states have now adopted the 0.08 standard. The federal government has pushed states to lower the legal limit. The now adopted the 7.00 standan says that a person can become impaired when the blood alcohol level hits 0.05. You should never drive an automobile when you are impaired by alcohol, drugs, or lack of proper rest.
Precautions
-
- You should wait 20 minutes after eating or drinking before testing. Any alcohol remaining in the mouth or saliva takes this long to disperse and will interfere with the reading.
-
- Avoid testing in a strong wind or in a closed room with dirty air.
-
- When the "BATT LOW" LED is on, replace 9V alkaline battery.
-
- Do not blow smoke or liquid into the unit. It will damage the sensor. Wait 1 minute after smoking before a test.
-
- Although CA2000 analyzes alcohol level accurately, do not use it as a tool to drink and drive.
-
- Store the unit between 32-104 (°F) and out of the reach of children.
-
- Do not leave CA 2000 car adaptor hooked up to cigar jack.
-
- Do not teave CA 2000 requires calibration every 12 months to obtain accurate results. Discuss with local distributors for calibration.
Troubleshooting
Replace the battery if the BATT LOW lamp comes on. Refer other problems to the toll free number below. No user serviceable components inside. Attempting to service the unit yourself voids the warranty.
Cleaning Instructions
For sanitation reasons, replace plastic mouthpiece if another person is going to use the unit. r of samation readsen topiated with a damp cloth. Do not submerge in water. This will void the warrantee. No routine maintenance other than yearly calibration is required.
