Optical detection device capable of rapidly heating and cooling

Abstract

The invention provides an optical detection device capable of rapidly heating and cooling. The detection device comprises a base frame assembly, a temperature control assembly, a detection assembly and a power assembly, wherein the temperature control assembly, the detection assembly and the power assembly are arranged on the base frame assembly; the power assembly comprises a hot flow pump and acold flow pump; the detection assembly comprises a light detection channel and a sample containing piece located on the light detection channel; the temperature control assembly comprises a heat flowstorage pool, a cold flow storage pool and a high-low temperature flow channel; the heat flow storage pool is communicated with the high-low temperature flow channel through the hot flow pump; the cold flow storage pool is communicated with the high-low temperature flow channel through the cold flow pump; the high-low temperature flow channel is located around the sample containing piece and usedfor enabling a to-be-detected substance in the sample containing piece to conduct heat exchange with a hot flow medium or a cold flow medium, and the environment temperature of the to-be-detected substance is rapidly changed. After the sample containing piece is arranged around the high-low temperature flow channel, the to-be-detected substance in the sample containing piece exchanges heat with the hot flow medium or the cold flow medium, the temperature of the environment where the to-be-detected substance is located is rapidly changed, and therefore the propagation speed of the to-be-detected substance is increased, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection of DNA, bacteria or viruses, in particular to a light detection device capable of rapidly raising and lowering the temperature. Background technique [0002] In the process of photodetection of cell substances, it is often necessary to add a detection substance that can adhere to the substance to be tested after the cell substance to be tested has grown and multiplied, so as to complete the detection. However, the current detection devices generally have the problem of slow cultivation of DNA, bacteria or viruses, etc., resulting in low detection efficiency. Contents of the invention [0003] Aiming at one or more deficiencies in the above-mentioned prior art, the present invention provides a light detection device capable of rapidly raising and lowering the temperature, which can effectively increase the propagation speed of the substance to be tested. [0004] In order to achieve the above ...
