Example Embodiment

[0023] Example 1: Determination of alanine aminotransferase (ALT) activity

[0024] Dry chip type rapid detector, light source 1 adopts light-emitting diode, photosensitive element 2 adopts ordinary photosensitive diode. The angle between the light source and the photodiode is fixed at 15 degrees. The detection temperature is controlled by the chip, and the constant temperature is 30-45℃±1℃. Built-in micro printer, add LCD digital display and fix the plastic case. The IC card is pre-written with the ALT logic operation mode and the compensation value of the corresponding batch of ALT dry film detection board.

[0025] Detection steps:

[0026] 1. Turn on: the instrument performs self-test and warms up.

[0027] 2. Adding samples: Take 35μl of blood from the fingertips, add the sample and the sample slot of the ALT dry chip test board, then put the test board in the test board inlet and outlet compartment 11 of the dry chip rapid tester, and press "Start" To start testing.

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...
