Technical Field

The invention relates to an analysis device, in particular to a sample introduction system and a sample introduction method of the analysis device.

Background

The analyzing device is used for analyzing body fluid (such as blood, urine or other liquid in vivo) collected from a living body and diagnosing according to the analysis result. In order to improve the detection efficiency, some analysis devices adopt a flow line type sample introduction system to provide samples to be detected for the analysis devices, and the sample introduction system mainly has the functions of inputting, dispatching, transmitting, positioning and recovering the sample rack and has the function of automatically identifying the barcode information of the sample rack and the sample tubes.

At present, the sample introduction system of the analysis device mainly has the following 2 types of modes in the input area and the recovery area.

1. Fixed bin channel type

In patent CN 203929791U, a sample rack conveying system is introduced, which comprises a sample rack conveying track and a sample rack. Wherein, the sample rack conveying track is in a fixed bin channel type. Each bin channel can be used for storing the sample rack to be tested and also can be used for recovering the sample rack after the test is finished. Each channel has sample rack in-position detection and status indication functions. Each channel is provided with a travel switch, whether a sample rack is placed or not is detected, and the state of the position is prompted to a user through an indicator lamp.

This configuration, due to the use of fixed bin lanes as compartments between the sample racks, allows a user to pick and place sample racks individually, which is not suitable for large sample runs. Meanwhile, each bin channel only corresponds to one sample rack, so that when samples are sucked, other sample racks to be detected cannot be stored even if the bin is idle, the occupied space is large, and resource waste is caused.

2. Independent placing area and recovery area

The sample introduction system of some instruments adopts an input area and a recovery area which are mutually independent. When the placing area has a space, a user is supported to place the sample rack at any time. The recovery area is positioned at one side of the placing area, and a user can take a plurality of sample racks from the recovery area in a centralized way.
