Description
Technical Field
The application belongs to the technical field of diagnostic instruments, and particularly relates to an intelligent sample loading device and method suitable for an in-vitro diagnostic instrument.
Background
Among the several in vitro diagnostic apparatuses, the operation process can be roughly divided into: the sample management unit loads the sample → the reagent management unit loads the reagent → the incubation or centrifugation unit reacts → the interpretation unit interprets the result, the instrument structure is mainly composed of the four components combined with other systematic components such as electric control and liquid path, so the efficiency, stability and functionality of the sample management unit greatly influence the performance of the whole diagnostic instrument.
Common sample management units can be classified into the following two types from their installation positions:
1) a sample management unit fitted outside the instrument;
2) a sample management unit installed inside the instrument;
the sample management unit matched with the outside of the instrument is mainly applied to the connection of a plurality of diagnostic instruments and is mainly characterized in that: the sample management unit is a unit component which is positioned outside the diagnostic instrument and exists independently, and because the sample management unit is positioned outside, the available space is larger, the function is more complete, the sample management unit is connected with the diagnostic instrument in series through a sample transmission channel, the sample capacity in the sample management unit is large, the sample storage and the sample transmission of a single sample management unit for a plurality of diagnostic instruments can be realized, but the occupied area, the cost and the like are higher;
the sample management unit installed in the instrument is mostly applied to a single diagnostic instrument, and is mainly characterized in that: the sample management unit is installed in the diagnostic instrument and exists as a small part in the instrument, the available space of the sample management unit is limited by the diagnostic instrument, the functions which can be effectively realized are fewer, and the sample capacity is smaller. But the system can ensure the basic requirements of sample management of a single diagnostic instrument by using a smaller occupied area;
there are two options when the customer uses only a single diagnostic instrument:
A. diagnostic instrument + external sample management unit
B. Diagnostic instrument with sample management unit inside
Compared with a diagnostic instrument and an external sample management unit, the diagnostic instrument with the internal sample management unit has the advantages of unit area diagnostic flux and cost.
However, because the internally mounted sample management unit is mounted inside the instrument, its external dimensions are limited in various ways, and its efficiency, function, stability, etc. are similarly limited. The currently available instruments have the following disadvantages for installing the sample management unit inside:
1) the sample can be conveyed in one direction only and cannot return back;
2) the sample management unit has no emergency intelligent queue-inserting function; when the emergency treatment is needed, the response time of the emergency treatment is long unless manual intervention is carried out for the queue;
3) continuous sample adding cannot be performed, and a new sample cannot be added to a sample conveying queue before a current batch of loaded samples is processed;
4) the position of the code scanner is fixed, the bar codes on the test tube and the sample rack are identified and read by moving the sample rack, and a larger space is needed for executing code scanning action;
5) has no function of preventing cross infection.

9. The intelligent sample loading device of claim 8, wherein the robot drive assembly (22) comprises:
a driving assembly main body (223) mounted on a guide rail provided in a third direction through a slider;
the horizontal driving module (224) is provided with a synchronous belt mechanism arranged along a third direction and is used for driving the driving component main body (223) to move;
the lifting driving module (225) is fixed on the driving component main body (223) and comprises a motor and a lifting rack, the lifting rack is installed on the driving component main body (223) and can move up and down, and a driving shaft of the motor is connected with the lifting rack through a gear so as to drive the lifting rack to lift;
the manipulator (21) is fixedly connected with the lifting rack, a buckle (211) is arranged at the top of the manipulator (21), and the buckle (211) is used for being clamped into the bottom matching part of the sample rack to realize connection with the sample rack.
10. A method for intelligent sample loading, using the intelligent sample loading device of any one of claims 1-9, comprising the steps of,
and (3) conventional detection: the common sample sampling channel (11) transmits a sample rack to be detected along a first direction, when the detected sample rack is transmitted to the rearmost part, the sample rack is transmitted to the sample unloading channel (12) through the sample transmitting channel (2), and the sample unloading channel (12) transmits the detected sample rack along a second direction;
emergency detection: the transmission of the common sample sampling channel (11) is suspended, then the sample returning mechanism (4) returns the currently detected sample to the common sample sampling channel (11), the emergency sample rack is taken away from the emergency sample platform (3) through the manipulator (21) for detection, after the detection is finished, the emergency sample rack is transferred to the sample unloading channel (12) through the manipulator (21), and then the sample is sent out through the sample unloading channel (12); then restarting the conventional detection;
exclusion of cross-infection: the identification codes of the samples are read through the code scanning assembly (6), the information of each sample to be detected is recorded, whether the samples to be detected are in cross infection risk or not is judged by means of a system database, and therefore the detection sequence of each sample on the current sample rack is scheduled, and two or more adjacent sample detection sequences which are possibly in cross infection are diverged.
