High-flux automatic chromatographic detection device

Abstract

The present invention discloses a high-flux automatic chromatographic detection device, comprising a chromatographic device; a test strip pushing device which is disposed above the chromatographic device and used for driving a detection mechanism to slide along an outer wall of a liquid storage tank such that a sample pad of a test strip contacts a sample liquid flowing into each detection channelof a reactor chamber; a switch driving device for driving a switch mechanism to motion such that the liquid storage tank is connected to or disconnected from each detection channel of the reactor chamber; an oscillation device for driving the chromatographic device to vibrate; a bar scanning device for collecting information of an identification code disposed on the detection mechanism; an imagecollection device for collecting an image of a display area on the test strip; and a control device, wherein the test strip pushing device, the bar scanning device, the image collection device, the switch driving device and the oscillation device are respectively electrically connected to the control device. The device of the present invention can realize automatic sample adding, automatic shakingup and automatic detection, such that manual operation is not required in the entire process. Therefore, the device greatly improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of biochemical detection, in particular to a high-throughput automatic chromatography detection equipment. Background technique [0002] Chromatographic detection is an important form of on-site rapid detection in recent years, and it is popular in clinical, food safety, environmental testing and other fields because of its convenience and speed. At present, chromatography often requires the application of multiple test strips to detect multiple indicators on a single sample. When testing, the common practice is to place the sample liquid in a common cavity, then put the test strips in, and read the results at a specific time. [0003] However, in the process of implementing the embodiments of the present invention, the inventors of the present application found that the above-mentioned technology has at least the following technical problems: [0004] (1) It is only suitable for one-step chromatography an...

Problems solved by technology

Such time requirements put forward higher requirements for the operator, and it is easy to make mistakes when faced with a variety of samples, and it is also easy to miss the time point, resulting in inaccurate results

[0006] (3) When reading the test strips, it is usually only possible to read one by one, which affects the timeliness of the readings. In order to improve the consistency of the reaction time, it is necessary to manually remove the sample pad that is full of samples, which makes the operation inconvenient and easy to contaminate sample

However, the remaining sample liquid on the chromatographic membrane still makes the reaction time inconsistent, and the accuracy of the results is reduced.
