Microchip testing device

Abstract

Microchip testing device having a chip holder that can be exactly positioned and from which adhered sample liquid can be removed easily. The microchip testing device has a chip holder, with a cover and a box area, mounted on a measurement stage, a microchip that has an optical measurement chamber is housed in the chip holder, a light source that radiates light on the optical measurement chamber of the microchip, a detector that receives light that has passed through the optical measurement chamber, and a controller that controls the device. The chip holder has reference planes to position the microchip in two directions perpendicular to the optical axis of the optical measurement chamber and pushers that push the microchip against the reference planes, so that the microchip is positioned within the chip holder by closing the cover of the chip holder.

Description

technical field [0001] The present invention relates to a microchip testing device for analyzing sample liquid by using a microchip through a photometric analysis method. Background technique [0002] In recent years, an analysis method using a microchip called μ-TAS or Lab.on a Chip has attracted attention. This analysis method uses semiconductor microfabrication technology and micromachining technology to make it smaller than conventional devices. chemical analysis, etc. When μ-TAS is used in the medical field, for example, the burden on patients can be reduced by reducing the amount of samples such as blood, and the test cost can be reduced by reducing the amount of reagents. Furthermore, since the device is downsized, there is an advantage that inspection and the like can be easily performed. [0003] In the absorptiometry analysis using a microchip, (1) the sample liquid collected by a painless needle is introduced into the microchip, (2) the sample liquid in the micr...

Problems solved by technology

In this way, the analysis of the absorptiometry needs to be performed by strictly positioning the microchip 101, so the absorptiometry cannot be performed on the microchip 101 simply accommodated in the chip holder 102.

[0009] Moreover, when the sample liquid is injected into the microchip 101, the sample liquid may spill out

If the spilled sample liquid adheres to the chip holder 102, it will also affect the detection results of other microchips 101.
