POCT (Point-Of-Care Testing) detection device and sample blending device

Abstract

The invention provides a sample blending device. A sample is sent into reaction cavities arranged by levels; reaction liquid is pre-loaded in each reaction cavity; the sample is fully mixed with reaction liquid in each reaction cavity through the blending device; a liquid extraction device is arranged between two levels of reaction cavities; through a pressure extraction structure, the sample subjected to preorder blending processing is sent into the post-order reaction cavity; the tail end reaction cavity is connected with a reaction tube; and after the sample is processed by the reaction liquid in each reaction cavity, the sample is sent into the reaction tube to be subjected to nucleic acid amplification reaction. A plurality of reaction cavities are arranged to carry out level-by-levelprocessing on the sample, each reaction cavity conveys samples among different reaction cavities through the liquid extraction device capable of carrying out pressure extraction, and finally, the sample is sent into the reaction tube to be subjected to the nucleic acid amplification reaction. Different reaction cavities re arranged to carry out sample processing, the pressure extraction structureis used for carrying out sample conveying, a sample processing structure is simple, sample processing safety is improved through independent reaction cavities, and a sample processing result is reliable. The invention also provides a POCT detection device.

Description

technical field [0001] The invention relates to the technical field of POCT detection, and more specifically, to a POCT detection device and a sample mixing device. Background technique [0002] In the field of in vitro diagnostics (IVD, in vitro diagnostics), point-of-care testing (POCT, point-of-care testing) is an important research direction in the field of biomedicine. The main criteria of POCT are that no fixed testing site is required, reagents and instruments are portable, and can be operated in a timely manner. POCT does not require specialized clinical testing services. In recent years, due to the development of today's high-tech and medical science, as well as efficient and fast-paced working methods, POCT, which has the advantages of miniaturization of experimental instruments, simple operation, and instant report results, has become more and more popular. [0003] For molecular diagnosis, the most commonly used clinical detection method is fluorescent quantita...
