Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the accompanying drawings. The following examples are only used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] A closed pathogen detection cartridge 1 related to the present invention is mainly composed of a slide 101, a cavity 102, a buckle cover 103, a base 104, a pipetting assembly 105, and a centrifuge tube 106. The slide 101 is fixed on the In the pipetting assembly 105, the movement of the pipetting assembly 105 drives the slide 101 to move along the U-shaped guide groove 201 in the cavity 102, and the upper part of the pipetting assembly 105 uses the buckle cover 103 to buckle the cavity through the buckle cover protrusion 301. The body 102 is fixed in the cavity 102 in the vertical direction, and can move along the upper edge of the cavity 102 and the protruding elongated beam 202 in the horizontal direction. The centrifuge ...

Abstract

The invention provides a closed pathogen detection cassette which comprises a cavity, a sliding blade arranged on the closed cavity, a pipette assembly combined with the sliding blade, a button lid, and a pedestal which is matched and combined with the cavity. The cassette can complete the whole pathogen detection process (including nucleic acid extraction, amplification and detection) in a closed environment, and is suitable for automatic control. The cassette can effectively avoid the problem of pollution in amplification detection of pathogenic microorganisms and the like, the problem of infection of the experiment operators, and other problems.

Description

technical field [0001] The invention relates to a closed pathogen detection cartridge, which is suitable for a portable and automatic biochemical detection system and belongs to the fields of biology, analytical chemistry and medical detection. Background technique [0002] Nucleic acid detection has been widely used in biomedicine and other fields. The entire process of traditional nucleic acid detection (including nucleic acid extraction, PCR amplification, and detection) needs to be operated on different instruments, and samples need to be transferred multiple times, which greatly increases the chance of cross-contamination of samples, especially from PCR amplification. Contamination occurred during the operation of taking samples after opening the cover. As a result, the final test result is inaccurate, which brings very serious harm to patients. Although a series of methods have been developed to prevent cross-contamination of amplification products, such as strict pa...
