PURPOSE: An apparatus for measuring blood alcohol concentration is provided to measure the alcohol concentration of a person, who is in the loss of consciousness, in a short time by measuring alcohol concentration using a metering module including a metering pin in one side of a collection container in which blood is collected.CONSTITUTION: A first main body part(80) is formed in a joint part(82) with which a collection container is combined. A second body part(90) is hinge-coupled with the first main body part and is circulated to cover the joint part. Alcohol concentration, which is measured at in a metering module(91), is displayed in a display(71). A metering pin(93) passes through and is connected with one side of the collection container in the joint art. A heater heats the inside of the joint part. An insertion hole, in which the metering pin is inserted, is formed in a blowpipe. An inlet hole is formed in one side of the collection container and a blood intake hole is formed in a circumference of the collection container. An absorbent member absorbs blood flowing in through the blood intake hole.COPYRIGHT KIPO 2012본 발명은 출혈이 동반된 의식불명자의 채혈의 곤란함을 해소하고 사고현장에서 즉시 혈액을 통해 의식불명자의 혈중알코올농도를 용이하게 측정할 수 있을 뿐만 아니라 피측정자의 호기를 통해서도 알코올농도를 측정할 수 있는 혈중알코올농도 측정기에 관한 것이다. 본 발명에 따르면, 혈중알코올농도 측정기에 있어서, 상기 측정기(60)에는 혈액이 채집된 채집용기(1)의 일면에 관통결합되어 혈액 또는 혈액내의 알코올가스를 흡입하도록 된 검침핀(93)과, 이 검침핀(93)에 의해 유입된 혈액 또는 알코올가스를 통해 알코올농도를 측정하는 측정모듈(91)이 구비된 것을 특징으로 하는 혈중알코올농도 측정기가 제공된다.
