Microchip testing device

Abstract

An absorptiometry microchip testing device with which, after one-time startup, test results of blood analyses are automatically obtained without a special tester. The microchip testing device has a rotary drive source which can be stopped at a prescribed angle; a centrifugal rotor connected to the rotary drive source via the main shaft; a direction switching mechanism for controlling the main shaft gear; a planetary gear which engages the main shaft gear which is located on the centrifugal rotor; a chip holder which turns together with the planetary gear; a microchip which is held in the chip holder and has a part for measuring absorbance; a light source from which light is incident in the absorbance measuring part of the microchip; a detector which receives light transmitted by the absorbance measuring part; and a controller which controls movements of the rotary drive source and the direction switching mechanism.
