The present disclosure relates to a method for processing a sample in an analyzable state and analyzing it in a molecular diagnostic system.
Nucleic acid amplification has been suggested as an essential process for a wide range of methods in molecular biology. For example, Miller, H. I. et al. (WO 89/06700) discloses a method for amplifying a nucleic acid sequence comprising hybridizing a promoter/primer sequence to target single-stranded DNA (“ssDNA”), and then transcribing many copies of the RNA of the sequence. Other known nucleic acid amplification methods include a transcription-based amplification system (Kwoh, D. et al., Proc. Natl. Acad. Sci. U.S.A., 86:1173 (1989); and Gingeras T. R. et al., WO 88/10315).
The most frequently used nucleic acid amplification method known as a polymerase chain reaction (hereinafter, referred to as “PCR”) includes a repeated cycle process of denaturation of double-stranded DNA, oligonucleotide primer annealing to a DNA template, and primer extension by a DNA polymerase (Mullis et al., U.S. Pat. Nos. 4,683,195, 4,683,202 and 4,800,159; Saiki et al., (1985) Science 230, 1350-1354).
PCR-based techniques are widely used in scientific applications or methods in the field of biological and medical research as well as amplification of a target DNA sequence, and include, for example, reverse transcriptase PCR (RT-PCR), fractional display PCR (DD-PCR), cloning of known or unknown genes by PCR, fast amplification (RACE) of the cDNA end, arbitrary priming PCR (AP-PCR), multiplex PCR, SNP genome typing, and PCR-based genome analysis (McPherson and Moller, (2000). BIOS Scientific Publishers, Springer-Verlag New York Berlin Heidelberg, NY).
The PCR-based techniques described above determine the presence of a target nucleic acid in a sample by amplifying and detecting the target nucleic acid of interest. In particular, where the target nucleic acid is associated with a particular disease (e.g., where the target nucleic acid is derived from a particular pathogen), the presence of the target nucleic acid may help diagnose the disease risk in the subject.
In order to confirm whether a target nucleic acid is present in a sample by amplifying and detecting the target nucleic acid, a thermal circulation mechanism for amplifying the nucleic acid and an optical mechanism for detecting the amplified nucleic acid are required. In the related art, a thermal cycler mechanism was performed in a thermal cycler, and an optical mechanism was performed in an electrophoresis device, but as a RT-PCR device capable of performing real-time PCR was developed, amplification and detection of nucleic acid are performed in one device.
In addition, in order to amplify and detect a target nucleic acid of interest, PCR based techniques require the use of reagents for target nucleic acid detection, including oligonucleotides that specifically hybridize to the target nucleic acid (e.g., primers and/or probes), labels, DNA polymerases, dNTP, Mg ions and buffers, etc. There is a need for a preparation process to prepare samples for nucleic acid amplification and detection using the reagents for target nucleic acid detection, and the preparation process is carried out in a liquid handling device.
Therefore, the sample on which the preparation process for nucleic acid amplification and detection is performed is moved from the liquid handling device to the RT-PCR device by the user who performs the experiment, and then the target nucleic acid included in the sample is amplified and detected.
However, when the user directly moves the prepared sample to the RT-PCR device, there is a problem in that contamination of the sample or contamination of the user by the sample may occur during the movement. Further, there is a problem in that the user must wait to move the sample from the preparation device while the sample preprocessing is performed in the preparation device. This is because a sample including an enzyme for detection should immediately perform a reaction for detection in the RT-PCR device, and when the sample is left at room temperature, a non-specific reaction by the enzyme may be performed.
There is a need for a new analyzing method and system to overcome this problem.

The transport device transports a reaction vessel and the like between the sample preparation unit and the sample analysis unit. To this end, the sample analysis unit includes a first local opening, and the sample preparation unit includes a second local opening.
The first local opening is located locally in the sample analysis unit. The second local opening is located locally in the sample preparation unit. Being located locally means being located only in a part of the whole.

Accordingly, the sample analysis unit and the sample preparation unit may maximize the rate of closure to the outside. Also, the exchange of unintended material and energy involved in the transfer of intended material, such as a reaction vessel, between the sample analysis unit and the sample preparation unit can be minimized.
According to an embodiment of the present disclosure, the sample preparation unit, sample analysis unit, and transport device are enclosed.
Enclosing means preventing the exchange of material or energy with the outside. The material or energy may be gas, sound, heat, or light. In addition, the material may be a reaction vessel, a sample, or a reagent which is introduced or discharged while a molecular diagnostic system operates.
The enclosing of the present disclosure comprises not only a sealed enclosing which completely prevents the exchange of materials or energy with the outside, but also a substantially enclosing which enables the exchange of materials or energy with the outside to be performed in a controlled state.
The enclosing may be implemented by providing a housing. For example, the enclosed sample preparation unit may include a housing, and devices included in the sample preparation unit may be located in the housing of the sample preparation unit. Alternatively, that the sample preparation unit is enclosed may mean that devices included in the sample preparation unit form their own housings. For the substantial enclosing, the housing may be provided with a material movement passage such as an opening. For the substantial enclosing, the housing may be provided with a device for exchanging air and heat, such as a fan, a slit, and a heat exchanger.

In an embodiment of the present disclosure, the passthrough cavity may include a first local opening included in the sample analysis unit and a second local opening included in the sample preparation unit.
According to an embodiment of the present disclosure, the first local opening is a gate-type opening. The gate-type opening is not always open, but is selectively opened when necessary.

For example, the first local opening of the sample analysis unit may be opened during the transport step and closed during the sample preparation step and the sample analysis step. The gate-type opening includes a door device.
According to an embodiment of the present disclosure, the second local opening of the sample preparation unit may be a gate-type or non-gate-type opening. Specifically, the second local opening of the sample preparation unit may be a non-gate type opening and may be located on a lower surface of the sample preparation unit.
According to an embodiment of the present disclosure, the first local opening is located on the top surface or the side surface of the sample analysis unit, and the second local opening is located on the bottom surface or the side surface of the sample preparation unit.

Among the components described in the embodiment of the present disclosure, those overlapping the description of the molecular diagnostic system of
(a) Preparation Step. Step of Preparing an Analysis Sample in a Reaction Vessel Using a Liquid Handling Device of a Sample Preparation Unit of the Molecular Diagnostic System
In the preparation step (a), an analysis sample is prepared in a reaction vessel.
The preparation of the analysis sample is performed through the molecular diagnostic system of the present disclosure. The molecular diagnostic system includes: a sample preparation unit, a sample analysis unit, and a transport device. The sample preparation unit, the sample analysis unit, and the transport device are enclosed. The sample preparation unit and the sample analysis unit are aligned such that reaction vessels is transportable from the sample preparation unit to the sample analysis unit by the transport device.
Specifically, the preparation of the analytical sample is performed using a liquid handling device in the sample preparation unit.
The analysis sample preparation may include a step of extracting a nucleic acid sample from the specimen. The preparing of the analysis sample may include a step of mixing the extracted nucleic acid with a reaction reagent for analysis in order to analyze the extracted nucleic acid. The nucleic acid extraction may include the step of disrupting cells contained in the specimen, and the step of isolating nucleic acids from the disrupted material. The disruption of cells for exposing active ingredients such as nucleic acids may be performed by physical or chemical processing methods such as heat processing, ultrasonic processing, acid, and base processing. The nucleic acid extraction may be performed through a nucleic acid extraction process known in the art (see, e.g., Sambrook, J. et al., Molecular Cloning. A Laboratory Manual, 3rd ed. Cold Spring Harbor Press (2001)). The nucleic acid extraction process may vary depending on the type of the specimen.
Reaction solutions or reagents for analyzing extracted nucleic acids may include buffers, stabilizers, enzymes, salts, nucleic acid fragments, dNTP, detection probes, optical labels, and supporting or separating polymer beads, resins, etc.
According to an embodiment of the present disclosure, the step (a) of preparing an analysis sample may include: extracting, by the liquid handling device, a nucleic acid sample from a specimen; and preparing an analysis sample including the extracted nucleic acid and a reaction reagent.
In order to perform the preparation step, the sample preparation unit may be provided with a sample container in which a specimen is contained, a reagent container in which a reagent used for extraction and/or the reaction solution described above is contained, and a reaction vessel in which a mixture of a nucleic acid extracted from the specimen and the reaction reagent is contained.
The containers should be disposed at a predetermined position in the sample preparation unit so that the liquid handling device can process the accurate solution according to a predetermined order. To this end, as shown in
According to an embodiment of the present disclosure, the preparing step (a) may include preparing a positive control reaction mixture.
The positive control reaction mixture is for confirming that the analysis reaction has been normally performed. The positive control reaction mixture is a mixture of reaction solutions or reagents for analyzing nucleic acids from which the same substances (positive control substances) as the target analyte to be detected in the sample are extracted. To prove the validity of the analysis, the positive control reaction mixture is reacted simultaneously with the analysis sample under the same conditions.
The positive control vessel is a container containing the positive control material. A positive control vessel accommodates a high concentration of a positive control material. When the positive control material is contaminated with the analysis sample, valid analysis is impossible. Therefore, the possibility of contamination may be minimized by using the positive control vessel to which the pierceable cap is attached in the molecular diagnostic system. The pierceable cap is a stopper for a liquid sample storage container which can prevent evaporation or contamination of a solution while a pipette can enter the storage container in a state of being coupled to the stopper without opening and closing the stopper.
According to an embodiment of the present disclosure, the reagent container may include a positive control vessel having a pierceable cap attached thereto, and the step (a) of preparing of the analysis sample may include preparing a positive control reaction mixture in the reaction vessel by the liquid handling device piercing through the pierceable cap of the positive control vessel.
(b) Transporting Step. Step of Transporting the Reaction Vessel from the Sample Preparation Unit to the Sample Analysis Unit by the Transport Device Through a Passage Formed by a First Local Opening of the Sample Analysis Unit and a Second Local Opening of the Sample Preparation Unit.
In the transporting step (b), the reaction vessel is transported.
The transported reaction vessel is the reaction vessel provided by the sample preparation unit in the (a) preparation step. The reaction vessel is, not limited thereto, but may be, for example, an analysis sample vessel, which is a reaction vessel that can be accommodated in a sample analysis device of the sample analysis unit. According to an embodiment, the analysis sample vessel may be a reaction vessel containing a predetermined amount of an analysis sample containing a target nucleic acid or a predetermined amount of an analysis sample not containing a target nucleic acid.
The local opening refers to an opening that is formed only in one part of the entire region. The first local opening is located locally in the sample analysis unit. The second local opening is located locally in the sample preparation unit.
The method of the present disclosure uses a molecular diagnostic system in which the first local opening is formed in the sample analysis unit and the second local opening is formed in the sample preparation unit, and the method of the present disclosure is characterized in a reaction vessel is transported by a transport device through a passage formed by the first local opening of the sample analysis unit and the second local opening of the sample preparation unit.
The second local opening of the sample preparation unit is located at the lower surface or the side surface of the sample preparation unit, and the first local opening of the sample analysis unit is located at the upper surface or the side surface of the sample analysis unit. Specifically, according to an embodiment, the second local opening may be located at the lower surface of the sample preparation unit, and the first local opening may be located at the upper surface of the sample analysis unit. Such arrangement of the local openings is suitable when the sample analysis unit is positioned under the sample preparation unit and is arranged vertically.
According to another embodiment, the second local opening may be located on a side surface of the sample preparation unit, and the first local opening may be located on a side surface of the sample analysis unit. Such arrangement of the local opening is suitable when the sample analysis unit and the sample preparation unit are positioned side by side and arranged left and right. Specifically, when the sample analysis unit and the sample preparation unit are disposed side by side, according to an embodiment, the first local opening and the second local opening may be disposed on the side surface of the sample analysis unit and the side surface of the sample preparation unit, respectively, to face each other. Alternatively, according to another embodiment, the first local opening and the second local opening may be disposed at a side and rear surface of the sample analysis unit and a side and rear surface of the sample preparation unit, respectively.
Accordingly, the sample analysis unit and the sample preparation unit may maximize the rate of closure to the outside. Also, the exchange of unintended material and energy involved in the transfer of intended material, such as a reaction vessel, between the sample analysis unit and the sample preparation unit can be minimized. Further, the structure of the transport device can be simplified.
The first local opening of the sample analysis unit is a gate-type opening. The gate-type opening is as described in the detailed description of a molecular diagnostic system. The first local opening, which is the gate-type opening, is opened during the transporting step of the step (b), and is closed during the sample preparation and sample analysis of the steps (a) and (c). Thus, the exchange of undesirable substances and energy between the sample analysis unit and the external environment may be minimized.
According to an embodiment of the present disclosure, a sealer may be further included in the sample preparation unit or the sample analysis unit. The sealer seals the inlet of the reaction vessel, in particular the analysis sample vessel. After the sample preparation unit injects the analysis sample into the analysis sample vessel, the sample analysis unit seals the analysis sample vessel before analyzing the analysis sample. Thus, the evaporation and contamination of the analysis sample are prevented. According to an embodiment, the sealer may be an automated sealer.
According to an embodiment of the present disclosure, the transporting step of step (b) may include transporting the reaction vessel containing the analysis sample to the sealer in the sample preparation unit by the liquid handling device, and transporting the sealed reaction vessel to the sample analysis unit by the transport device.
When the sealer is located in the sample preparation unit, the reaction vessel may be moved to the sealer by the liquid handling device.
The reaction vessel including the analysis sample may be transported to the sealer in the sample preparation unit by the liquid handling device by using a gripper channel of the liquid handling device.
The gripper channel is a means for moving a solid object such as a reaction vessel in the liquid handling device. In an embodiment, the gripper channel may be a pipetting channel of a pipetting module of the liquid handling device to which a gripper is coupled.
The sealed reaction vessel is transported to the sample analysis unit by a transport device. The sealed reaction vessel is delivered to a transport device by a liquid handling device.
According to an embodiment of the present disclosure, the transporting of the reaction vessel in the step (b) may include: transporting the reaction vessel including the analysis sample to the sample analysis unit by a lift module of the transport device; transporting the reaction vessel to a sealer of the sample analysis unit by a crane module of the transport device; and transporting the reaction vessel sealed in the sealer to an analysis device of the sample analysis unit by the crane module of the transport device.
When the sealer is located in the sample analysis unit, the reaction vessel may be moved to the sealer by a transport device. Specifically, the reaction vessel including the analysis sample is transported to the lift module of the transport device by the liquid handling device in the sample preparation unit, and the lift module moves the reaction vessel from the sample preparation unit to the inside of the sample analysis unit.
The reaction vessel moved into the sample analysis unit is transported from the lift module to the sealer by the crane module of the transport device to seal. The sealed reaction vessel is transported to the sample analysis device by a crane module again.
According to an embodiment of the present disclosure, the transporting step (b) may include the following steps (b1) to (b3):
(b1) when preparing the analysis sample of the step (a) is completed, placing the transport device at a position capable of accommodating the reaction vessel; (b2) mounting the reaction vessel on the transport device by the liquid handling device; and (b3) transporting the mounted reaction vessel to the sample analysis unit by the transport device through a passage formed by the first local opening of the sample analysis unit and the second local opening of the sample preparation unit.
(b1) when Preparing the Analysis Sample of the Step (a) is Completed, Placing the Transport Device at a Position Capable of Accommodating the Reaction Vessel
When the reaction vessel containing the analysis sample is prepared by the liquid handling device, the transport device moves to a position capable of accommodating the reaction vessel and is located. The transport device moving to the receiving position of the reaction vessel is a lift module. As shown in
According to an embodiment of the present disclosure, step (b1) may include the following step (b10).
(b10) sensing, by the transport device, a preparation complete signal recorded after completion of the analysis sample preparation step of the step (a), and moving the transport device.
The method of the present disclosure is a method in which the transfer module is informed that the preparation of the reaction vessel to be transported from the sample preparation unit to the sample analysis unit is completed, and the method as in step (b10) may be used.
The liquid handling device of the sample preparation unit records predetermined information (preparation complete signal) indicating that preparation of the reaction vessel is completed in a specific storage means when preparation of the reaction vessel is completed. The storage means is a storage means to which both the liquid handling device and the transport device can access. The storage means may be, for example, a memory, a processor, or a hard disk, to which a liquid handling device and a transport device are connected by wire or wirelessly. The predetermined information may be creation or deletion of a file or folder of a specific format or name, recording of specific information in a file, or deletion of the recording.
The transport device periodically refers to a position where the predetermined information is to be provided, and senses and moves when the predetermined information is provided.
When the transport device reaches a position capable of accommodating the reaction vessel, the liquid handling device mounts the reaction vessel to the transport device.
Specifically, the mounting may be that the gripper channel of the liquid handling device mounts the reaction vessel to the analysis sample vessel rack of the lift module.
Even in step (b2), the liquid handling device should be able to detect whether the lift module, which is the transport device, reaches a position capable of accommodating the reaction vessel.
To this end, according to an embodiment of the present disclosure, step (b2) may include the following step (b20).
(b20) mounting, the reaction vessel on the transport device by the liquid handling device detecting a transport ready signal recorded by the transport device being positioned at a position where the reaction vessel is accommodable.
Similar to step (b10), when the transport device reaches a position capable of accommodating the reaction vessel, the transport device records a transport ready signal, which is predetermined information indicating that preparation for receiving the reaction vessel is completed, in a specific storage means. The storage means is the same as described in step (b10). However, a storage means for recording the transport ready signal and the preparation complete signal, a recording location, and a format of the signal may be different from each other.
It may be recognized by a position sensor that the transport device is located at a position capable of accommodating the reaction vessel. According to an embodiment of the present disclosure, the transport device may include a position sensor, and the step (b2) comprises detecting, by the position sensor, that the transport device is positioned at a position where the reaction vessel is accommodable, and recording a transport preparation completion record according to the detection by the sensor.
The liquid handling device periodically refers to a position at which the transport ready signal is to be provided after recording the preparation complete signal of step (b10), detects the transport ready signal when the transport ready signal is provided, and mounts the reaction vessel in the analysis sample vessel rack of the lift module.
When the reaction vessel is mounted on the lift module of the transport device by the liquid handling device through steps (b1) and (b2), the transport device transports the mounted reaction vessel to the sample analysis unit. The transport is performed through the movement path which is formed by the first local opening and the second local opening.
The above-described signal transmission scheme is a unique scheme of the present disclosure. According to the method of the present disclosure including the above method, the preparation, transport, and analysis of the reaction vessel can be normally performed even when the liquid handling device and the transport device of the sample preparation unit are not controlled by the same controller or control software.
According to an embodiment of the present disclosure, the sample analysis unit may include a sample analysis device, and the transporting of step (b) may include the following steps (b4) to (b6).
(b4) transporting the reaction vessel from the sample preparation unit to the sample analysis unit by a transport device through the passage formed by the first local opening of the sample analysis unit and the second local opening of the sample preparation unit; (b5) preparing the reaction vessel to be accommodated by the sample analysis device when the transport device is located at a position where the reaction vessel can be transported to the sample analysis device; and (b6) mounting the reaction vessel to the sample analysis device by the transport device.
The sample analysis unit may include a sample analysis device. The sample analysis device is as described in the detailed description of a molecular diagnostic system.
The transport step (b) of the method of the present disclosure may be a step of mounting the reaction vessel prepared in the sample preparation unit on a sample analysis device in the sample analysis unit. To this end, when the transport device transports the reaction vessel to the sample analysis unit and reaches a position to be mounted on the sample analysis device, the sample analysis device prepares to receive the reaction vessel.
The reaction vessel is accommodated by placing the reaction vessel in the reaction vessel accommodating portion of the sample analysis device so that the sample analysis device can perform analysis. Preparation to accommodate the reaction vessel refers to the act of allowing the transport device to position the reaction vessel in the reaction vessel receiving portion of the sample analysis device.
Specific preparation for receiving a reaction vessel of the sample analysis device may vary depending on the structure of the sample analysis device. For example, in the case of the sample analysis device according to an embodiment of
When preparation for receiving the reaction vessel is completed, the transport device mounts the reaction vessel to the sample analysis device. As shown in
According to an embodiment of the present disclosure, step (b5) may include the following step (b50). (b50) Step of the sample analysis device preparing to accommodate the reaction vessel by detecting a transport ready signal recorded by the transport device located at a position capable of transporting the reaction vessel to the sample analysis device.
When the transport device reaches a position capable of transporting the reaction vessel to the sample analysis device and is ready to transport the reaction vessel, a transport ready signal, which is predetermined information indicating that preparation for transporting the reaction vessel is completed, is recorded in a specific storage means. The storage means is a storage means to which both the sample analysis device and the transport device can access. The storage means may be, for example, a memory, a processor, or a hard disk, to which a liquid handling device and a transport device are connected by wire or wirelessly. The predetermined information may be creation or deletion of a file or folder of a specific format or name, recording of specific information in a file, or deletion of the recording.
The sample analysis device periodically refers to a location where the transport ready signal is to be provided, and when the transport ready signal is provided, the sample analysis device detects the same and prepares to accommodate the reaction vessel.
Even in step (b6), the transport device must be able to detect whether the sample analysis device has completed preparation to accommodate the reaction vessel.

(b60) Step of mounting the reaction vessel on the sample analysis device by sensing an accommodation ready signal recorded in a state in which the sample analysis device can accommodate the reaction vessel by the transport device.
Similar to the step (b50), when the sample analysis device is in a state of being capable of receiving the reaction vessel, the sample analysis device records an accommodation ready signal, which is predetermined information indicating that preparation for receiving the reaction vessel is completed, in a specific storage means. The storage means is the same as described in step (b50). However, a storage means for recording the transport ready signal and the accommodation ready signal, a recording location, and a format of the signal may be different from each other.
(c) Analysis Step. Amplifying and Analyzing the Analysis Sample Accommodated in the Reaction Vessel in the Sample Analysis Unit.
In step (c), an analysis sample is analyzed using the reaction vessel transported to the sample analysis unit. The analysis is performed by a sample analysis device of a sample analysis unit.
The analysis may mean, for example, obtaining information on the presence, content, concentration, sequence, activity, or characteristic of an analyte in a sample. Analytes may include a variety of substances (e.g., biological substances and non-biological substances such as compounds). Specifically, the analytes may include biological materials such as nucleic acid molecules (e.g., DNA and RNA), proteins, peptides, carbohydrates, lipids, amino acids, biological compounds, hormones, antibodies, antigens, metabolites, and cells. According to an embodiment of the present disclosure, the analyte may be a nucleic acid molecule.
The sample analysis device of the present disclosure may be a target nucleic acid detection device. A target nucleic acid detection device allows a nucleic acid reaction in a sample to proceed, and a target nucleic acid is detected through this.
A nucleic acid reaction refers to a series of physical and chemical reactions that generate a signal depending on the presence or amount of a nucleic acid of a specific sequence in a sample. The nucleic acid reaction may be a reaction including a binding between a nucleic acid of a specific sequence in a sample and another nucleic acid or material, or a replication, cleavage, or degradation of a nucleic acid of a specific sequence in the sample. The nucleic acid reaction may be a reaction accompanied by a nucleic acid amplification reaction. The nucleic acid amplification reaction may include amplification of a target nucleic acid. The nucleic acid amplification reaction may be a reaction that specifically amplifies a target nucleic acid.
The nucleic acid reaction may be a signal-generation reaction that may generate a signal depending on the presence/absence or amount of a target nucleic acid in a sample. This signal-generating reaction may be a genetic analysis process such as PCR, real-time PCR, microarray, etc.
Various methods of generating an optical signal indicating the presence of a target nucleic acid using a nucleic acid reaction are known. Representative examples include the following: TaqMan™ probe method (U.S. Pat. No. 5,210,015), molecular beacon method (Tyagi et al., Nature Biotechnology v. 14 Mar. 1996, Scorpion method (Whitcombe et al., Nature Biotechnology 17:804-807 (1999)), Sunrise or Amplifluor method (Nazarenko et al., 2516-2521 Nucleic Acids Research, 25 (12): 2516-2521 (1997), and U.S. Pat.

The target analyte detection device according to an embodiment of the present disclosure may be a nucleic acid detection device, and may detect a signal generated depending on the presence of a target nucleic acid. A nucleic acid detection device may amplify and detect a signal together with nucleic acid amplification. Alternatively, the nucleic acid detection device may amplify and detect a signal without accompanying nucleic acid amplification. Preferably, the signal is detected by nucleic acid amplification.
A sample analysis device according to an embodiment of the present disclosure may include a nucleic acid amplification device. The nucleic acid amplification device refers to a device capable of performing a nucleic acid amplification reaction that amplifies a nucleic acid having a specific nucleotide sequence.
According to an embodiment of the present disclosure, the sample analysis unit may include a ventilation apparatus configured to form an air-out flow.
Since the nucleic acid reaction by the sample analysis device proceeds inside the sample analysis unit, a lot of heat is generated. In order to control the temperature inside the sample analysis unit, the sample analysis unit may include a ventilation apparatus.
According to an embodiment, a duct for guiding the air discharged by the ventilation fan may be additionally configured. Accordingly, it is possible to prevent the air discharged by the ventilation fan from approaching the sample preparation unit located on the upper part of the closed structure.
According to an embodiment of the present disclosure, the ventilation apparatus may be operated while performing the step (c). According to an embodiment of the present disclosure, the ventilation apparatus may not be operated during the transporting step of the step (b) and/or the sample preparing step of the step (a).
The sample analysis device generates a lot of heat during the operation process. Since the ventilation apparatus has an effect of discharging heat generated from the sample analysis device inside the sample analysis unit, the ventilation apparatus should be operated while performing step (c) of operating the sample analysis device.
When in the alternative the sample analysis device is in a standby state by power applied thereto in the entire process of processing and analyzing the sample in the molecular diagnostic system, the ventilation apparatus should also be operated in the entire process of operating the molecular diagnostic system.
However, while the reaction vessel is being moved to the sample analysis part, it is necessary to stop the ventilation apparatus in the sample analysis part to prevent contamination. The contamination includes both contamination of the sample analysis unit by substances in the reaction vessel and contamination of the reaction vessel by substances in the air in the sample analysis unit.
Therefore, according to an embodiment of the present disclosure, the ventilation apparatus may not be operated while the transporting step of the step (b) is performed. Alternatively, the ventilation apparatus may not be operated from when the reaction vessel is carried into the sample analysis unit by the transport device until analysis by the sample analysis device starts. In this case, the reaction vessel may be an unsealed reaction vessel.
Meanwhile, the method of the present disclosure may further include a step of discarding the reaction vessel when the analysis step (c) is finished. According to an embodiment of the present disclosure, the method may further include, after performing step (c), discarding the reaction vessel by the crane module of the transport device.
As shown in
According to an embodiment of the present disclosure, the sample preparation unit may perform UV irradiation while the molecular diagnostic system is maintained in a non-operational state and/or while step (c) is performed.
The UV irradiation is for sterilization in the sample preparation unit. The UV irradiation of the present disclosure may in particular be performed while performing step (c). According to the method of the present disclosure, the first local opening of the sample analysis unit is a gate-type opening, and the first local opening is closed while the step (c) is performed as a feature. Therefore, even when UV irradiation is performed in the sample preparation unit while performing the step (c), the UV does not affect the sample analysis unit in which analysis of the analysis sample is being performed.
