Description
Technical Field
The invention belongs to the technical field of in-vitro diagnosis, and particularly relates to a sample feeding method.
Background
Current laboratory pipelines employ a sample tube holder carrying a single sample tube to transport the sample tube. In order to transfer the sample tubes in the laboratory flow line to the analysis device for detection, a sample delivery system is required between the laboratory flow line and the analysis device. The sample feeding system is used for conveying an undetected sample tube on a laboratory flow line to analysis equipment, and simultaneously transferring the sample tube after analysis to the laboratory flow line, and the process is as follows: the sample tube is transferred into the sample rack, the sample rack is transferred into analysis equipment for detection, and after the detected sample rack returns to the sample rack storage area, the detected sample tube is transferred onto the assembly line. Although the existing sample feeding system can meet the use requirements to a certain extent, the following disadvantages still exist:
1) All sample frames are sent into the analysis equipment through an online assembly, and before the conventional sample frames in the online assembly do not enter the analysis equipment, emergency sample frames can only be sequentially queued to enter the analysis equipment, so that the emergency detection efficiency is low;
2) Only two sample rack channels are arranged in the sample rack storage area, namely a conventional sample rack channel and an emergency sample rack channel, the conventional sample rack can only be transferred into the online assembly through the conventional sample rack channel, and the emergency sample rack can only be transferred into the online assembly through the emergency sample rack channel, so that the flexibility of the sample feeding system is poor, and different sample racks cannot be prioritized according to actual detection requirements;
3) After the sample tube is transferred onto the sample rack from the laboratory assembly line, the bar code directions of the sample tube are inconsistent, so that the code scanner cannot accurately read sample information in the detection process.
Disclosure of Invention
Accordingly, the present invention is directed to a sample feeding method, which can make a sample rack with higher priority enter an analysis device to detect preferentially, thereby improving efficiency.
In order to achieve the above purpose, the present invention provides the following technical solutions:
the sample feeding method comprises the steps of setting a priority for each sample rack placing position in a sample rack storage bin, reading sample information of a sample pipe positioned at an operation track unloading station, obtaining the priority of the sample pipe, and transferring the sample pipe into a sample rack positioned at a corresponding priority of the sample rack storage bin;
during the continuous transfer of the sample tube into the sample rack, the analyzer is presented with the following steps:
step one: if the sample rack storage bin is full of the sample rack or a preset rack conveying condition is met, transferring the sample rack to a rack transporting trolley, and transferring the sample rack to a sample channel with corresponding priority in an online buffer unit for buffer storage by using the rack transporting trolley;
step two: judging whether a sample rack exists at an inlet and an outlet of the analyzer: if yes, executing the fourth step; if not, executing the third step;
Step three: according to the priority order from high to low, finding out a sample frame with the highest current priority in the online buffer unit, adjusting the position of the online buffer unit, butting and communicating a sample inlet channel where the sample frame is positioned with an inlet and an outlet of an analyzer, transferring the sample frame into the analyzer for detection, and executing the second step;
step four: judging whether a sample rack exists in the return channel: if yes, executing the step six; if not, executing the fifth step;
step five: the position of the online buffer unit is regulated to align the return channel with the inlet and outlet of the analyzer, and the detected sample rack is transferred to the return channel; executing the second step;
step six, transferring the detected sample rack in the return channel to a rack transporting trolley;
step seven: reading sample rack information through the mark on the sample rack, and judging whether the sample rack is correct or not: if yes, executing the step eight; if not, returning the original path of the sample rack;
step eight: obtaining a corresponding sample rack placing position according to the sample rack information of the sample rack, and transferring the sample rack to the corresponding sample rack placing position by utilizing a rack transporting trolley;
step nine: the inspected sample tube placed in the sample rack is transferred into a sample tube holder located at the handling rail loading station.
Further, the priority is set to be at least two stages, the lowest priority is a conventional level, and the highest priority is an emergency level; in the first step, different rack feeding conditions are preset for the sample racks with different priorities.
Further, for a sample rack with a conventional priority, the rack feeding condition is that the sample rack is fully loaded; for a sample rack with an unusual level of priority, the rack feeding condition is that the sample rack is full, or that no second sample tube is transferred into the sample rack within a set time interval after the last sample tube is transferred into the sample rack.
Further, for a sample rack with priority of emergency treatment, the rack feeding conditions are as follows: the sample rack is fully loaded; or, no second sample tube is transferred into the sample rack within a set time interval after the last sample tube is transferred into the sample rack; or, at least one emergency sample tube is loaded on the emergency sample rack, and no second emergency sample rack exists in the operation channel between the track entrance and the unloading station.
In the first step, the rack transporting trolley transfers the sample rack into the fixed channel of the on-line assembly, and simultaneously adjusts the position of the on-line buffer unit to align the sample channel corresponding to the priority of the sample rack in the on-line buffer unit with the fixed channel, and then transfers the sample rack into the sample channel corresponding to the priority.
Further, before transferring the sample tube into the sample rack in the sample rack storage bin, the bar code attached to the sample tube is positioned as follows:
s1: driving sample tube seats in the operation channels to sequentially reach an unloading station;

s6: controlling the sample tube to rotate towards the second direction by a second preset angle theta 2 Then step S11 is performed;
s7: controlling the sample tube to rotate towards the second direction by a third preset angle theta 3 Then step S11 is performed;
s8: controlling the sample tube to rotate towards the second direction by a fourth preset angle theta 4 ；
