Problems solved by technology

However, the disadvantages of this device are: 1. The device is large in size and is not suitable for large-scale production and transportation of finished products; 2. The test strips in the device are complicated to install and are not suitable for large-scale test paper assembly and production; 3. After the device is restarted and used , can be reopened easily and without traces, so the nucleic acid amplification product is only relatively closed. If the device that has been reacted is opened unintentionally, the contamination of the amplification product is inevitable; 4. The device In this method, only a single reaction solution can be detected, but multiple reaction solutions cannot be detected, that is, the detection of multiple samples cannot be completed on one test strip in the form of multiple reaction solutions
This is not conducive to environmental protection, but also increases the difficulty and cost of injection molding production

Abstract

The invention discloses an enclosed chromatographic test strip plastic card box. The enclosed chromatographic test paper plastic card box is characterized in that the box includes a bottom card (2) and an upper case (1), the upper case (1) and the bottom card (2) are fitted together at four edges through embedding so as to define enclosed interior space, the bottom card (2) is provided with a long groove (21) for disposing one or more chromatographic test strips, no gap is left on the bottom card (2) for communication with the exterior, and the upper case (1) is provided with an enclosable sample solution adding zone (12) and a chromatographic test strip detection result observation zone (13). According to the invention, after addition of a sample solution is completed, enclosure of the card box can be realized, so a detected sample substance is prevented from doing harm to operating personnel and polluting the environment. The plastic card box provided by the invention has a simple structure, batch injection molding production of the plastic card box is easy, and batch assembly production of test strips is simple.

Description

technical field [0001] The invention relates to a plastic cartridge for chromatography test paper for biochemical diagnosis and detection, in particular to a closed plastic cartridge for chromatography test paper. Background technique [0002] The lateral flow chromatography test paper technology (Lateral Flow, US6,485,982) invented by Charlton in 1988 realized the new technology of directly obtaining the test results after one-step sample addition. Immunochromatographic test paper represented by nano-colloidal gold labeling technology has been promoted to the fields of rapid detection of medicine, veterinary medicine, food safety and biosafety. Dry chemical or biochemical test paper has also begun to use chromatography test paper. When the detection solution of the chromatography test paper contains substances that are harmful to the operator and the environment, such as Bacillus anthracis, dioxin, etc. It will seriously endanger the health of operators and pollute the en...
