The present invention relates to a nucleic acid amplification test apparatus, and an automatic sample analysis system having the same and, more particularly, to a nucleic acid amplification test apparatus in which separation and purification, dispensation, amplification, and testing of samples are performed integrally, and an automatic sample analysis system having the same.
A gene amplification test method is an in vitro diagnostic testing (IVD testing) technology that amplifies a gene having a specific sequence to determine whether the gene exists and is used in various fields such as food inspection, GMO inspection, as well as pathogenic microorganism inspection and genotype inspection of various animals and plants, including humans.
In order to perform an accurate gene amplification test from various biological samples, first, a nucleic acid extraction process of removing various reaction inhibitors contained in the sample, which inhibits the gene amplification reaction, from the sample to acquire high-purity target nucleic acid is required.
The target nucleic acid extracted in this manner is mixed with a gene amplification solution to perform the gene amplification reaction, and then, DNA corresponding to a length of DNA of a gene amplification product is confirmed, or fluorescence generated from the gene amplification product is confirmed to complete the gene amplification test.
More specifically, the gene amplification test may be a method for amplifying a target nucleic acid, and various methods such as PCR, nested PCR, RT/PCR, and isothermal nucleic acid amplification have been developed. Generally, the gene amplification test may be performed through a preparation process of mixing the extracted target nucleic acid with the gene amplification reaction solution to prepare a gene amplification reactant and a reaction process of proceeding the reaction.
In particular, the gene amplification reaction process only needs to maintain a constant temperature in the case of the isothermal amplification, but when using the PCR, a heating and cooling process is required for temperature cycling reaction. In this process, the temperature has to be raised, and thus, a reaction tube is usually sealed to prevent evaporation from occurring.
In spite of the release of various automation systems, in the related art, after the reactant containing the target nucleic acid is dispensed from an automatic purification and dispensing apparatus in order to seal an inlet, which is an accommodation portion of the reaction tube, a user directly seals the inlets of the plurality of reaction tubes by using a sealing means such as a sealing film or a sealing film and then puts the target nucleic acid into the automatic purification and dispensing apparatus.
In this process, since the sealing of the inlet of the reaction tube is performed through the user's direct intervention, a preparation time for the gene amplification reaction process increases, and an entire test time of the gene amplification test increases together. As a result, there is a problem in that, since the entire processes of the gene amplification test are not fully automated, inspection efficiency is deteriorated, and cost and time increase.
In addition, since the user has to directly seal the inlet of the reaction tube with the sealing film in a state in which the reactant in the reaction tube is exposed from the outside of the nucleic acid amplification test apparatus, there is a problem that the reactant in the reaction tube may be contaminated by aerosol or the like.
In order to solve the above problems, an object of the present invention is to provide a nucleic acid amplification test apparatus, in which a process of dispensing a solution into a reaction tube, a process of performing sealing, and a nucleic acid amplification test process are continuously and automatically performed, and an automatic sample analysis system having the same.

For example, the sample may be a biological sample and may mean blood, urine, tissue, saliva, sputum, etc., containing the target nucleic acid obtained from living organisms, and may further include the living body itself such as animals, plants, and microorganisms.
Thus, the automatic sample analysis system according to the present invention may perform analysis by purifying the target nucleic acid to be analyzed from the sample and detecting the target nucleic acid through the amplification of the target nucleic acid.
The automatic purification and dispensing apparatus 10 may be a configuration that separates and purifies the target nucleic acid to dispense the target nucleic acid into the plurality of reaction tubes 1 at the dispensing position P, and various configurations are possible.
That is, if the automatic purification and dispensing apparatus 10 is configured to amplify the nucleic acid through the nucleic acid amplification test apparatus 20 to be described later and purify the target nucleic acid to be measured in real-time, thereby dispensing the target nucleic acid into the nucleic acid amplification test apparatus 20, the automatic purification and dispensing apparatus 10 may be applied to any type of apparatuses disclosed in the related art and thus will be briefly described below.
For example, the automatic purification and dispensing apparatus 10 may include a purification unit that includes a multi-well plate kit (not shown) containing a reagent necessary for purification of the sample to purify the target nucleic acid from the sample and a pipette block 12 on which a plurality of pipettes 11 is detachably mounted to move the sample, the reagent, and the target nucleic acid.

The pipette block 12 is a configuration in which the plurality of pipettes 11 are detachably mounted to move the sample, the reagent, and the target nucleic acid used during the purification, and various configurations are possible.
For example, the pipette block 12 may have a plurality of insertion holes so that the plurality of pipettes 11 is inserted with the columns to suction and discharge the sample, the reagent, the target nucleic acid, and the like.
Here, the pipette block 12 may transfer the target nucleic acid obtained through the purification unit to the nucleic acid amplification test apparatus 20 through relative movement with the multi-well plate 40 to be described later.
In this process, the pipette block 12 may perform the relative movement with the multi-well plate 40, and a detailed relative movement process will be described later.
The pipette block driving unit may drive the pipette block 12 in at least one of the upward, downward, left, or right direction so that the plurality of pipettes 11 of the pipette block 12 move various samples, reagents, target nucleic acids, etc., to suction and discharge the various samples, reagents, target nucleic acids, and the like at a fixed position.
In the pipette block driving unit, various types of driving means disclosed in the related art may be applied, and for example, electric motor driving, hydraulic actuator driving, and the like may be used.

However, as described above, when the processes of mixing the target nucleic acid solution obtained from the automatic purification and dispensing apparatus 10 with the nucleic acid amplification kit and performing the sealing to move to the nucleic acid amplification test apparatus 20 are manually performed, there is a problem in that a risk of contamination and a total analysis time increase due to user's intervention.
In order to solve this problem, as illustrated in
The housing 30 is configured to form the inner space S1, and various configurations are possible.
For example, the housing 30 may have a rectangular parallelepiped shape and form the inner space S1 isolated from the outer space, and the multi-well plate 40 provided with the plurality of reaction tubes 1 may be inserted and carried out.
For this, the multi-well plate insertion unit 100 may be provided with a shutter 60 on one surface thereof so that the multi-well plate insertion unit 100 supporting the multi-well plate 40 moves to be reciprocated between the inner space S1 and the dispensing position P for receiving the target nucleic acid through the automatic purification and dispensing apparatus 10.
More specifically, the housing 30 may be provided with a shutter 60 on one surface on which the multi-well plate insertion unit 100 is disposed so that the multi-well plate insertion unit 100 is movable between the inner S1 and the dispensing position P in the state in which the multi-well plate insertion unit 100 supports the multi-well plate 40.
Here, the shutter 60 may include a door part 61 forming a portion of one surface of the housing 30 and a door hinge 62 enabling opening and closing through rotation of the door part 61.
That is, when the door part 61 is pressed as the multi-well plate insertion unit 100 moves, the shutter 60 may be opened by the hinge rotation through the door hinge 62 of the door part 61, and the multi-well plate insertion unit 100 may move.
In the state in which the door part 61 is opened by the hinge rotation through the door hinge 62, the door part 61 may be maintained in the opened state through partial interference with the multi-well plate insertion unit 100.
As another example, in the state in which the door part 61 is opened by the hinge rotation through the door hinge 62, the rotation of the door part 61 may be stopped through a member fixing the door hinge 62, and then, the door part 61 may be maintained in the opened state.
In the state in which the multi-well plate 40 move to the dispensing position P of the automatic purification and dispensing apparatus 10 through the movement of the multi-well plate insertion unit 100, the target nucleic acid may be received through the automatic purification and dispensing apparatus 10 and then automatically move to the inner space S1 so that the amplification and detection of the nucleic acid are performed.
The multi-well plate insertion unit 100 may be a configuration that supports the multi-well plate 40 provided with the plurality of reaction tubes 1 and is movably installed between the dispensing position P and the inner space S1, and various configurations are possible.
For example, the multi-well plate insertion unit 100 may include a support part 110 configured to support an edge of the multi-well plate 40 in which the plurality of reaction tubes 1 are provided, and a driving part 120 configured to drive the support part 110 between the dispensing position P of the automatic purification and dispensing apparatus 10 and an amplification position, at which the amplification of the target nucleic acid is performed, in the housing 30.
In addition, the multi-well plate insertion unit 100 may further include a support driving block 130 provided at each of both lower ends of the support part 110 to connect the support part 110 to the driving part 120.
The multi-well plate 40 may be a configuration in which the plurality of reaction tubes 1 are formed in a plurality of columns, and various configurations are possible.
In particular, if the multi-well plate 40 is a configuration capable of accommodating the target nucleic acid to amplify and detect the target nucleic acid to be analyzed, any configurations disclosed in the related art may be applied.
For example, the multi-well plate 40 may be a configuration in which the plurality of reaction tubes 1 are coupled or supported to the plate 41, and as another example, the multi-well plate 40 may be a configuration in which a plurality of unit wells are formed on the plate 41 to accommodate the target nucleic acid through the wells.
The support part 110 may be a configuration that supports the edge of the multi-well plate 40 on which the plurality of reaction tubes 1 are provided, and various configurations are possible.
For example, the support part 110 may have an opening 111 in a center thereof to prevent interference with the reaction tube 1 of the multi-well plate 40 and include a stepped part 112 for supporting the multi-well plate 40.
That is, the support part 110 may be provided in the inner space S1 to support and move the multi-well plate 40 so that the multi-well plate 40 is disposed at a fixed position and more particularly moves to the dispensing position P at which the target nucleic acid is received from the automatic purification and dispensing apparatus 10.
The opening 111 may be a configuration provided so that the plurality of reaction tubes 1 pass through the support part 110 downward without interference and may be formed to correspond to a shape of the multi-well plate 40.
The plurality of reaction tubes 1 may be disposed at the lower side through the opening 111 in the state in which the plate 41 is supported on the stepped part 112 to control a temperature through the temperature control block 500.
The stepped part 112 may be a configuration for supporting the edge of the multi-well plate 40, and various configurations are possible.
The support driving block 130 may be a configuration provided at each of both the lower ends of the support 110 to connect the support part 110 to the driving part 120, and various configurations are possible.
The support driving block 130 may have an upper side coupled to the support part 110 at each of both the lower ends of the support part 110 and a lower side connected to the driving part 120 so that the support part 110 moves from the amplification position in the inner space S1 to the dispensing position P through driving force of the driving part 120.
More specifically, the support driving block 130 may include a support plate 131 coupled at each of both lower ends of the support part 110, a block part 132 connected to a driving belt 121 of the driving part 120 at a lower side of the support plate 131, and a driving guide 133 provided on the support plate 131.
Through this, since the support driving block 130 receives the driving force of the driving part 120 through the block part 132 to move, the driving force may be transmitted to the support part 110 connected to the support plate 131, as a result, the support driving block 130 may move between the amplification position and the dispensing position P together with the support part 110.
The drive guide 133 may be a configuration for guiding the movement of the support part 110 and may be provided on the support plate 131 to guide the movement of the support plate 131 and the support part 110 together with the guide member provided on an inner wall of the housing 30.
The driving part 120 may be a configuration that drives the support part 110 so as to be reciprocated between the inner space S1 of the housing 30 and the dispensing position P, and various configurations are possible.
For example, if the driving part 120 drives the support part 110 in the method disclosed in the related art, the driving part 120 may drive the support part through any method such as an electric motor type, a pneumatic type, a magnetic field linear motor, and the like.
For example, the driving part 120 may include a driving source 122 that receives external energy to perform rotational motion, a pair of pulley parts 123 and 124 connected to the driving source 122, and a driving belt 121 connected between the pair of pulley parts 123 and 124.
The driving source 122 may receive the external energy to perform the rotational motion as a motor and may rotate at least one of the pair of connected pulley parts 123 and 124 according to the rotational motion.
At least one of the pair of pulley parts 123 and 124 may rotate according to the rotation of the driving source 122, and the pair of pulley parts 123 and 124 may rotate vertically through the driving belt 121 to which the other one of the pair of pulley parts 123 and 124 is connected so that the driving belt 121 moves.
As described above, the driving belt 121 may be connected to the support plate 131 through the block part 132 of the support driving block 130, and as the driving belt 121 moves, the support plate 131 and the support part 110 may move.
The above-described movement may be performed in various directions like linear movement such as upward, downward, left, and right directions, and rotational movement, and more specifically, the side surface of the housing 30 of the nucleic acid amplification test apparatus 20 may linearly and horizontally move to allow the multi-well plate 40 to approach a side of the automatic purification and dispensing apparatus 10.
In the nucleic acid amplification test apparatus according to the related art, the user may directly seal a top surface of the multi-well plate 40 and transfer the multi-well plate 40 to the nucleic acid amplification test apparatus 20. Thus, there is a problem in that contamination occurs during the sealing process, constant sealing is difficult, and a total analysis time increases according to the sealing time to deteriorate analysis efficiency.
In order to solve these problems, the nucleic acid amplification test apparatus 20 according to the present invention may automatically receive the target nucleic acid obtained from the automatic purification and dispensing apparatus 10 and automatically perform the seal on the multi-well plate 40.
