Problems solved by technology

Therefore, since the reaction solution is irradiated with light from the side, and the light passing through the reaction solution is focused by the focusing lens and guided to the detector, each capillary can only detect the number of detections that can be arranged in a planar row at a time, and there is a limit detection. quantity problem
In addition, all of the light source, the mirror with the scanning mechanism, the reaction table, each capillary, the focusing lens, and the detection mechanism must be configured in a plane, and there is a problem that the installation area of ​​the device itself increases.

Abstract

An object is to provide a reaction detecting device in which a height dimension of the device itself can be set to be small to realize space saving, unevenness of measurement sensitivity for each reaction container is minimized, and high-sensitivity and high-precision reaction detecting is possible, the device includes: a reflective plate disposed above a temperature controllable reaction block disposed in a reaction chamber constituted in a main body to reflect light; and a light source lamp and a camera arranged in the main body, the light from the light source lamp is reflected by the reflective plate to enter each reaction container from above, and light such as fluorescence directed upwards from a reaction specimen is reflected by the reflective plate to enter the camera.

Description

technical field [0001] The present invention relates to a reaction detection device which promotes a reaction such as culture (amplification) by changing the temperature of a reaction sample such as DNA (deoxyribonucleic acid) collected from blood or a sample, and simultaneously proceeds with the reaction state, That is, the detection of the amount of amplification formed by culture. Background technique [0002] Conventionally, an incubator has been used to amplify a reaction sample such as DNA collected from blood or a sample. This incubator has an automatic DNA or RNA synthesis device using the phosphotriester method, and is formed to cover the outer periphery of the reactor with a thermal part, and a thermal module having a heating and cooling function using the Pelty effect is attached to the thermal part. , while burying the composition of the thermal module. [0003] In general, the method of synthesizing DNA or the like by the above-mentioned phosphotriester method...
