Currently ,the National Health and Health Commission released the New Coronary Virus Pneumonia Diagnosis and Treatment Plan (Trial Version 7), whose diagnostic criteria are to add serum testing (ie antibody and antigen testing) to the original nucleic acid testing and sequence testing. The application of new coronary pneumonia (2019-nCoV) IgM/IgG antibody detection kit (colloidal gold method) is playing an increasingly important role in the diagnosis and epidemic prevention and control of new coronary pneumonia.
In order to effectively contain the epidemic, ensure the restoration of public life order, and effectively organize the resumption of work and production of enterprises, IgM/IgG antibody detection kits (IgM/IgG antibody detection kits) IgM/IgG antibody detection kits are widely used. The demand for IgM/IgG antibody detection kits in my country has surged due to changes in diagnostic standards and a surge in demand for new coronary pneumonia (2019-nCoV) IgM/IgG antibody detection kits from a large number of enterprises. Therefore, how to quickly and safely produce products and bring them to the market in a timely manner is an urgent problem for these companies to solve. The unique UDI identification and customization requirements are an indispensable part of the POCT detection reagent card production process, and also a weak link in the production of some enterprises. In this regard, the first thing that comes to mind is laser inkless printing. Laser inkless printing is a consensus of POCT products in recent years. On the front line of anti-epidemic, Lesser Laser adheres to the POCT production line to ensure clear, accurate and fast signs on each test card, providing customers with 24-hour uninterrupted service.
Kit laser marking. Material of the kit. The main raw materials of polyester reagent cards are polymer materials (polyvinyl chloride, polypropylene, ABS, HIPS, etc.). The characteristics of polymer materials are as follows: (1) good physical and mechanical properties and chemical stability; (2) abundant sources, low price, suitable for making disposable medical products; (3) convenient processing, low manufacturing cost, suitable for various molding The method is convenient for processing into complex shapes and developing new products. Polymer laser processing is to use the high energy of the laser to promote the carbonization of the surface of the plastic itself, decompose some components on the surface to generate a green body, foam the plastic, and make the plastic in the laser-acting part and the non-functional area produce color difference, forming a logo, Its logo effect is good, and the production efficiency is high.
Laser marking principle According to the characteristics of polymer materials such as PVC, polypropylene, ABS, HIPS, four commonly used wavelengths of 355nm, 532nm, 1064nm, 10.64um are tested, and combined with different processes, it can be A better marking effect is obtained, but the differences between different materials are different. Finally, the four wavelength lasers of 355nm, 532nm, 1064nm and 10.64um are combined, and the lasers of three different technologies are selected 355nm, HIPS and HIPS. Using polymer materials for laser marking, due to the great changes in polymer chromatic aberration, we adjust through different laser technologies to produce different physical and chemical changes in polymer materials such as polyvinyl chloride, polypropylene, ABS, HIPS, etc., resulting in Chromatic aberration, improve polymer chromatic aberration contrast.
