Micro-fluidic chip for drug detection

Abstract

The invention discloses a micro-fluidic chip for drug detection. The micro-fluidic chip comprises a test box and a chip body, wherein a box door is hinged to the outer wall of the test box, a displayscreen and a plurality of buttons are arranged on the outer wall of the test box, a PLC is arranged in the test box, a plurality of pipeline connectors are symmetrically arranged on the outer wall ofthe test box in a penetrating mode, and a partition plate is fixedly connected to the inner wall of the test box. According to the invention, the test box, a vacuum pump, an atomizer, a temperature and humidity sensor and an electric heating plate are arranged, so low-temperature heating evaporation and constant-temperature humidification preservation of the chip body can be realized, and the chipbody does not need to be moved in the processes of evaporation and preservation, thereby effectively avoiding leakage of a reagent; the chip body can be isolated from outside air through the test box, so the influence of long-time exposure in the outside air on test precision is avoided; and the opening of the test box is large due to the arrangement of the L-shaped box door, so the chip body isconvenient to operate.

Description

technical field [0001] The invention relates to a detection chip, in particular to a microfluidic chip for drug detection. Background technique [0002] Drugs generally refer to drugs that make people addicted. The term drug here is a broad concept, mainly referring to opium, heroin, methamphetamine, etc. abused by drug addicts, and also includes dependent natural plants, tobacco, alcohol, and solvents. It is a different concept from medical drugs. Although chemicals such as morphine (Morphine), methamphetamine (Methamphetamine), and ecstasy (MDMA) were originally developed to treat human diseases and relieve human pain, they have serious side effects after use. Side effects, and addictive, so it is also included in the list of drugs. The abuse of drugs has brought great impact and harm to people's life and life safety. According to the information released by the National Narcotics Control Office, in 2016, the national drug control departments cracked 140,000 drug crimina...

Problems solved by technology

[0005] However, when the existing micro-control flow chips are used, they are usually exposed to the outside air for a long time, lack of effective isolation measures, and the detection results are easily affected by impurities in the air. Dry or moisturize the chip, so the chip has to be transferred multiple times, which may easily cause leakage of samples and reagents, and the use effect is not good
