A hand-held chemical detection device and a test piece applied to the chemical detection device

Abstract

The invention discloses a hand-held chemical detection device used for detecting of chemical components and a test piece, and can be applied to the filed of drug and narcotic drug detecting or food safety detecting. The test piece of the invention can comprises several test papers borne on a test piece substrate and a container used for storing a tested body. The several test papers can separately react with several chemical components and generate optical property changes. The hand-held chemical detection device of the invention can receive the test piece of the invention through an opening in a casing and senses and analyzes optical sensing information of the test piece through an optical sensor and analyzing module sensing, and thereby determining whether chemical reaction occurs between the test papers in the test piece and the tested body, i.e, whether specific chemical components are contained in the tested body.

Description

technical field [0001] The present invention relates to a hand-held chemical detection device for detecting chemical components, in particular to a hand-held chemical detection device for detecting whether a biological sample or substance contains a specific chemical component and a test piece applied to the chemical detection device. The detection device can be applied to the field of medicine, drug detection or food safety detection. Background technique [0002] In order to detect whether biological samples (such as: saliva, sweat, urine, blood, etc.) or substances (such as: food) contain specific chemical components (such as: designated drugs, specific drugs or other toxic substances), it is often required to be collected by the testing personnel Biological specimens or samples are transported back to the laboratory to be tested with special instruments to obtain test results, which causes additional transportation or transportation costs, and the test results cannot be ...

Problems solved by technology

[0004] However, in the prior art, the results of using test papers and reagents to detect chemical components need to be manually recorded, which causes inconvenience in application, and also causes technical problems such as cumbersome detection procedures, difficult preservation of test papers or reagents; although chemical detection and analysis instruments can be The sample is obtained through the collection device, and the test results are obtained and recorded through reagents, reactions and analysis. Limited by the existing technology, the volume and weight of the chemical detection and analysis instrument are not easy to carry around, and the cost of the chemical detection and analysis instrument is also high.
