The strip body has a first face and a second face. The strip body has an injection opening, a flow channel and a reaction receptacle. The injection opening reaches the first face, the flow channel is in fluid communication between the injection opening and the reaction receptacle, and the flow channel is in fluid communication with the injection opening through a flow channel opening. The blocking element is vertically movably disposed in the injection opening, and the blocking element selectively closes the flow channel opening. Therefore, the back flow of a sample can be prevented, so as to ensure chemical reaction of the sample and a reagent and thus improve accuracy of the test results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Test strip device","description":"Disclosed is a test strip device, comprising a strip body and a blocking element.
