Problems solved by technology

Antibody detection is to extract blood and use colloidal gold test method for detection. It has low requirements for the laboratory and is easy to operate. It is suitable for a large number of suspected cases and asymptomatic infections. The results can be obtained in 15 minutes at the fastest, but the detection sensitivity is lower than that of nucleic acid detection. More positive results

Embodiment Construction

[0024] This embodiment provides a device for optical detection of virus-infected cells, such as figure 1 As shown, the device includes a lighting module 1 , a control module 2 , a workbench 3 and a closed casing 4 . The lighting module 1 is used to illuminate the workbench 3 to cause physiological and chemical changes in target cells for subsequent detection of cell states or metabolites to obtain current state information of the cells to be tested. For example, the metabolites of the cells to be tested can be compared with the standard curve to realize a rapid preliminary judgment on whether the cells to be tested are infected by a certain type of virus. The control module 2 is used to set the parameters of the lighting module 1 and the ambient temperature of the workbench 3 . Workbench 3 is used to place the cell culture plate containing the cells to be tested. The closed casing 4 is used to isolate external microorganisms, so that the detection environment meets certain d...

Abstract

The invention relates to a device and a method for optical detection of virus-infected cells. The device comprises a workbench, a closed shell, an illumination module and a control module, wherein theworkbench is used for placing a cell culture plate, and the cell culture plate is used for placing cells to be detected; the closed shell is used for closing the workbench; the illumination module isused for illuminating the workbench; and the control module is used for controlling the irradiation condition of the illumination module and / or the working temperature of the workbench. The device and the method for optical detection of the virus-infected cells can assist in detection of the virus-infected cells, the operation method is simple, and consumed time is short.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for optical detection of virus-infected cells. Background technique [0002] Most of the current viral nucleic acid detection uses RT-PCR technology (reverse transcription polymerase chain reaction) to detect whether the subject is infected with the new coronavirus. Nucleic acid detection requires throat swabs to extract epithelial cells and nucleic acid, and then use a fluorescent quantitative PCR instrument for detection. The detection sensitivity is high, and the results can be obtained within 2 to 3 hours, but the requirements for equipment, environment and personnel operation are high. Antibody detection is to detect whether there is specific antibody IgM or IgG in the serum of the subject to determine whether the subject has ever been infected with the new coronavirus. Antibody detection is to extract blood and use colloidal gold test method for...
