Abstract

The invention relates to a dry-plate rapid detector, belonging to the field of medical devices. The dry-plate rapid detector comprises optical detection components (a light source and a photosensor), an integrated circuit board (which integrates a light source drive circuit and a signal acquisition / amplifying circuit) micro-converter chip, a display device, a temperature control device, an IC card reader, a micro-printer, a communication device, a detection plate charging and discharging bin, and a shell. The dry-plate rapid detector can achieve quantitative or qualitative rapid detection of various biochemical indexes of human blood samples (whole blood, plasma, serum) and make a timely diagnosis on the related diseases; the dry-plate rapid detector is characterized by high degree of automation, rapid and accurate detection, stable performance, easy and simple operation, compact machine structure, smart appearance and easy carrying.

Description

technical field [0001] The invention relates to a dry sheet type rapid detector. Specifically, it is a dry-sheet type rapid detector that can quickly quantitatively or qualitatively complete the simultaneous detection of multiple biochemical indicators by using a matching dry-sheet detection board. It belongs to the technical field of medical equipment. Background technique [0002] Medical examination has always been one of the most accurate and effective means of disease diagnosis. Today, with the rapid development of medical testing technology, people can use the advanced technology of various disciplines to serve clinical testing and diagnose diseases in a timely and effective manner. Since the end of the last century, people have applied fully automatic biochemical instruments integrating life science technology, electronic technology, computer technology and other advanced technologies to clinical biochemical testing, creating an automated path for biochemical projec...
