The portable breathalyzer accessory combines a blood alcohol content measuring tool with a mobile device to measure, store, and send the blood alcohol content of the user. The portable breathalyzer device attaches to a mobile device, wired or wirelessly, to display the blood alcohol content of the user, which is measured through the portable breathalyzer attachment. The blood alcohol content is displayed as a percentage on the mobile device through the corresponding software application. The software application shows the user their blood alcohol content in comparison with the local blood alcohol content limit, which is found by determining the user's location through the GPS technology of the mobile device.

A device for measuring blood alcohol concentration for detecting the alcohol concentration from the blood of the unconscious driver as well as the driver's breath, comprises a first body including a coupling recess into which the blood collection module is coupled and a heater for heating the coupled blood collection module, and a second body including a detection probe to penetrate the blood collection module to suck the alcohol gas in the blood collection module, and an alcohol detection sensor to detect the alcohol concentration through the alcohol gas introduced through the detection probe.

An apparatus and method for acquiring and analyzing a spectroscopic sample for a substance from a sampling region of the tissue of a person at an interstitial region between the fingers of the person, by way of a probe and a spectroscopic detector for radiating the interstitial region with electromagnetic radiation and analyzing a diffuse-reflectance signal obtained from the tissue at the sampling region. The apparatus preferably also incorporates a biometric sensor to perform a verification of the person.

The invention discloses a driving control system and method for persons driving while intoxicated and feeling uncomfortable. An alcohol sensor, a pulse sensor and a body temperature sensor are utilized for monitoring the blood alcohol concentration, the pulse condition and the body temperature condition of a driver respectively. When it is detected that the blood alcohol concentration inside the driver exceeds a threshold value, a central processing unit controls a relay switch to cut off a sparking plug circuit, an automobile engine stops operation and meanwhile an audio file is played. When the pulse fluctuation or the body temperature fluctuation of the driver exceeds the normal range, the central processing unit controls an audio player to play a relevant prompt audio file. The driving control system and method for the persons driving while intoxicated and feeling uncomfortable are used for eradicating drunk driving behaviors and monitoring whether the body conditions of the driver meet the driving conditions or not and are of great significance in maintaining the traffic order and guaranteeing the life and property safety of people.

The present invention is a test kit comprising a plurality of individually-sealed test strips, each for detecting the presence and intensity of alcohol in breast milk. Each test strip is formed from a porous (absorbent) carrier matrix, and a color-change reagent resident on the carrier matrix. The color-change reagent comprises an alcohol oxidase enzyme and a hydrogen donor indicator that changes color when oxidized. In addition, a comparative color chart is provided, including a plurality of color swatches, a numerical scale of blood alcohol concentration, and a quantitative safe/not safe warning. The reagent on the test strip indicates the presence of alcohol in breast milk. The test kit includes a number of test strips and a color chart to allow breast feeding mothers to ascertain the concentration of alcohol in their breast milk to ensure that breast milk fed to infants is free of alcohol.

The present invention relates to a vehicle safe starting device which controls the starting of a vehicle according to a driver's state. One embodiment analyzes blood alcohol concentration by projecting infrared rays into the driver's skin and receiving a reflected signal, and thereafter controls so that the vehicle is not stared if the blood alcohol concentration is larger than a reference value. Since a general breathalyzer using a driver's exhalation is not used, but infrared rays and a method of skin contact touch using a finger, etc. are used, it is possible to accurately measure the blood alcohol level without giving a driver inconvenience, and it is possible to preempt vehicle accidents by blocking driving in an inappropriate state.

An alcohol-metabolism enhancing composition contains theanine. The composition may be contained in ingesta. Theanine has an effect of quickly reducing blood alcohol concentration, thereby easing or improving troubles due to alcoholic ingestion such as hangover or alcoholic hepatic insufficiency.

The invention relates to a method and a system for noninvasively detecting a blood alcohol content based on Raman scattering. The method comprises the following steps: acquiring Raman scattering spectrum information of one group of alcohol solution blood samples with known concentration by adopting a transmission and reflection manner, establishing a quantitative mathematic relation between a blood alcohol concentration and the Raman peak strength of a Raman scattering spectrum to form a calibrating model; training the calibrating model and obtaining an optimal calibrating model; acquiring Raman scattering spectrum information of to-be-detected blood of a human body by adopting a transmission and reflection manner, and establishing a to-be-tested sample set; and denoising the obtained to-be-tested sample set by using a wavelet analysis method; and obtaining an alcohol concentration predicted value of detecting the blood of the human body by using the to-be-tested sample set as the input of the optical calibrating model. The system comprises a laser emitting module, a signal receiving module, a signal processing module and a digital display module which are sequentially connected. Compared with the prior art, the method has the advantages of rapidness, real time, noninvasive effect and the like.

A blood alcohol level sensing system for a vehicle is steering wheel with infrared sensors that are able to detect variations in body chemistry from contact with the palms of the hands to determine if a driver is either alcohol impaired or impaired from certain medical conditions that might affect driving. The system has a digital readout that may be located on the dashboard of the vehicle, and the readout may also be transmitted to a cell phone. In the event of an exceedance of a predetermined set point, an interlock will interrupt the start circuit of the vehicle to prevent it from starting.

A system operable to determine a future point of time, at which the alcohol concentration in blood of a user is less than a threshold value. The system includes an alcohol sensor operable to detect a current alcohol concentration in blood of the user, and a portable apparatus. The alcohol sensor and the portable apparatus comprises each a wireless communication apparatus. The wireless communication apparatus in the alcohol sensor is operable to wirelessly transmit the current alcohol concentration to the wireless communication apparatus in the portable apparatus.

The embodiment of the invention provides a safe driving duration determining method, a safe driving duration determining device and a terminal. The safe driving duration determining method comprises the following steps of obtaining the blood alcohol concentration of a user at the first moment; when the condition that the blood alcohol concentration is greater than the preset blood alcohol concentration is judged, obtaining the estimated duration of lowering the blood alcohol concentration to the preset blood alcohol concentration according to the blood alcohol concentration and an experience formula; and displaying the estimated duration through a display screen. By adopting the method, the duration of lowering the blood alcohol concentration to the preset blood alcohol concentration can be detected.

The invention disclosed herein includes nanocomplexes that are designed include enzymes that have complementary functional attributes and methods for using these nanocomplexes. Illustrative examples include nanocomplexes that comprise both an alcohol oxidase enzyme as well as a catalase enzyme. These nanocomplexes can be used in methods designed to lower blood alcohol levels in vivo, and/or to break down the toxic byproducts of alcohol metabolism. Consequently these nanocomplexes can be used to treat a variety of conditions resulting from the consumption of alcohol, including for example, acute alcohol intoxication.
