Detector and sample detection method

Abstract

The invention relates to a detector and a sample detection method. The detector comprises a flow pump set, a base, a detection unit, a conveying mechanism and a controller, wherein the detection unitand the conveying mechanism are arranged on the base; the detection unit comprises at least one sample pool, a sample adding head, an injection pump, a card bin and a sample detection chamber; the sample pool is communicated with the flow pump set and the injection pump at the same time, the injection pump is communicated with the sample adding head through the first sampling pipe, and the sampleadding head is suspended above the sample detection chamber; a detection card for sample detection is stored in the card bin; the conveying mechanism comprises a stepping motor and a toothed bar, wherein the stepping motor is fixedly connected with the toothed bar, the toothed bar is connected with the sample detection chamber through the bottom of the card bin, and detection cards stored in the card bin can be linked into the sample detection chamber along with the toothed bar so as to be used for sample detection; and the controller is respectively in control connection with the injection pump, the stepping motor, the reversing valve, the sample adding head and the flow pump set. The detector is simple in structural design, and can realize full-automatic rapid detection of samples.

Description

technical field [0001] The invention belongs to the field of sample detectors, in particular to a detector and a sample detection method. Background technique [0002] Sample detectors are widely used in water ecological environment monitoring, food testing, drug testing and other fields, but the existing detectors generally still require complicated manual processing, and samples can only be tested in the circulation link, the sample testing process is complicated, and the testing cycle is long , the detection efficiency is low; and the existing sample detection device does not fully consider the cleaning and protection of the flow path, which may easily lead to contamination of the detector, affect the accuracy of sample detection, and cannot prevent the growth of bacteria in the pipeline when the detection instrument is idle for a long time. Therefore, it is necessary to consider improving the structure of the existing sample detection device to realize automatic sample d...
