Device for detecting knockout drops in beverages

Abstract

Device for detecting psychoactive substances in liquids, characterized by, that the device measures the electrical conductivity of a liquid, These measurements are evaluated to detect possible adulteration of the liquid by psychoactive substances. and issues a warning via an automated feedback system if a potential contamination is detected.

Description

[0001] Current methods for detecting date rape drugs in drinks consist of test strips, cups, or stickers that show a color reaction when certain substances, such as GHB or ketamine, are present. In addition, there are complex laboratory-based procedures, such as high-performance liquid chromatography (HPLC), which, however, can only be performed in specialized facilities.

[0002] The problem with the first set of rapid tests is that they are insufficiently reliable, frequently produce false-positive or false-negative results, and are generally only suitable for certain types of beverages. Laboratory-based methods, on the other hand, are too complex, too expensive, and not suitable for direct everyday use.

[0003] The invention mentioned in claim 1 is based on the problem of providing a device that is able to electrochemically detect various knockout drops on site in a short time and to give immediate feedback on the result - either directly on the device itself or via a connected network.

[0004] The advantages of the invention lie particularly in the fact that it provides a reliable means of immediately testing beverages for dangerous substances. This is especially helpful for people in bars, clubs, or at events, as they can use the device to directly check whether their drink has potentially been tampered with. Another advantage is that it is a reusable device that requires no consumables and can be used for extended periods if used correctly. The invention also offers added value for catering establishments, as it can be used in a networked version where multiple devices communicate with a central station, enabling staff to be warned in a timely manner in case of an emergency.

[0005] The device is available either as a standalone pen with an integrated measuring unit and color display, or in a networked version that is also wirelessly connected to a central evaluation unit. In both cases, the analysis is performed using electrochemical measurement methods, which can reliably identify a wide variety of substances.

Claims

[1] Device for detecting psychoactive substances in liquids, characterized by , that the device measures the electrical conductivity of a liquid, These measurements are evaluated to detect possible adulteration of the liquid by psychoactive substances. and issues a warning via an automated feedback system if a potential contamination is detected. [2] Device according to claim 1, characterized by , that the measured values ​​are acquired using a potentiostat, which measures the current flow through an electrochemical cell.
