Description

The present invention relates to a storage container for accommodating a dispensing pipette.

With the development of genetic testing technology in recent years, it is possible to predict susceptibility to pharmaceuticals in advance by extracting nucleic acids from subjects such as biological samples collected from patients and detecting genetic differences such as single nucleotide polymorphisms. Sex is suggested.

When extracting nucleic acid from a subject, it is necessary to prevent cross-contamination between the specimens and prevent the spread of the infection source. Therefore, the reagents necessary for extracting nucleic acid from the subject are stored in the reagent cartridge, and each time the nucleic acid is extracted from the subject, these reagents are used up and the used reagent cartridge is discarded (for example). See Patent Document 1).

Dispensing pipettes used for dispensing reagents are also discarded after each use in order to prevent cross-contamination between specimens and to prevent the spread of infection sources (similar to reagent cartridges). For example, see Patent Document 2). The dispensing pipette described in Patent Document 2 is stored in a dispensing pipette tip rack (containment container) and discarded together with the storage container.

The dispensing pipette rack 200 shown in FIG. 1 contains a dispensing pipette tip 201 and a drilling pipette tip 202.

The reagent cartridge 100 contains a reagent or the like for extracting nucleic acid from a subject. By charging the subject into the reagent cartridge 100 and mounting the reagent cartridge 100 and the dispensing pipette rack 200 on a nucleic acid extraction device (not shown), the nucleic acid extraction work using the dispensing pipette tip 201 can be machined into the nucleic acid extraction device. Can be implemented as a target.

<Reagent cartridge>
The reagent cartridge 100 has a box-shaped main body 101 having an opening, and a claw portion 102 formed so as to project laterally from the outer surface of the main body 101. The claw portion 102 is used for fixing the reagent cartridge 100 to the nucleic acid extractor.

Inside the main body 101, a sample well (subject accommodating portion) 110 into which a subject such as a biological sample is charged, a reagent well portion 120 accommodating a reagent for extracting nucleic acid from the subject, and the like. A waste liquid well (waste liquid storage unit) 130 for discarding an unnecessary solution separated in the step of extracting nucleic acid from a subject and a recovery well 140 for collecting nucleic acid extracted from a subject are integrally provided. Further, the reagent cartridge 100 has an extraction filter cartridge 150 containing a carrier for adsorbing nucleic acid. The reagent cartridge 100 is provided with a holding portion 160 in which the extraction filter cartridge 150 is housed.

The reagent well unit 120 has a plurality of reagent wells (reagent accommodating units) 121, 122, 123, 124, 125, 126, an oil well (oil accommodating unit) 127, and an oil removing unit 128.

In the reagent well portion 120, the openings of the plurality of reagent wells 121 to 126, and the openings of the oil well 127 and the oil removing portion 128 are sealed by the sealing film 104 shown in FIG. The sealing film 104 suppresses the intrusion of gas into the reagent wells 121 to 126 and the oil well 127. The sealing film 104 is made of a material that can be pierced by the dispensing pipette tip 201 or the drilling pipette tip 202 described later. The sealing film 104 can be formed of, for example, a thin metal film, a plastic film, or the like.

In the reagent wells 121, 122, 123, 124, 125 and 126, a lysate 121A that dissolves a biological substance such as a cell membrane, and a biological substance such as a cytoplasm that cannot be completely dissolved by the lysate 121A and causes clogging in the carrier are dissolved. Dissolution 122A, cleaning solution 123A for washing away unnecessary substances other than nucleic acid adsorbed on the carrier, cleaning solution 124A, eluate 125A for eluting nucleic acid from the carrier, and diluting solution 126A for adjusting the nucleic acid concentration in the eluate. Each is housed.

The oil well 127 contains, for example, a well-known oil 127A used as a layer on a reaction solution in a PCR reaction. As the oil 127A, for example, mineral oil, silicon oil, or the like can be suitably adopted.

The oil removing unit 128 is for removing the oil 127A adhering to the outer surface of the dispensing pipette tip 201 when supplying the oil 127A to the dispensing pipette tip 201, and has a filter (not shown) inside.

The waste liquid well 130 has a shape corresponding to the outer shape of the bottom of the extraction filter cartridge 150, and is a recess that can support the extraction filter cartridge 150.

The dispensing pipette tip 201 is for dispensing and stirring the liquid contained in the reagent cartridge 100. The liquid contained in the reagent cartridge 100 is dispensed or stirred by any of the plurality of dispensing pipette tips 201, and the dispensing pipette tips 201 do not cause cross-contamination between the liquids.

The drilling pipette tip 202 is used to break through the sealing film 104 that seals the openings of the reagent wells 121 to 126, the oil wells 127, and the openings of the oil removing portion 128 to make holes. After drilling a hole in the sealing film 104 on each well using the drilling pipette tip 202, the dispensing pipette tip 201 is inserted into each well through this hole.

The dispensing pipette rack 200 is also a container for collecting the used dispensing pipette tip 201 and the drilling pipette tip 202, and is used as infectious waste after the use of the dispensing pipette tip 201 in the nucleic acid extractor. The dispensing pipette tip 201 and the drilling pipette tip 202 can be discarded together with the dispensing pipette rack 200.

FIG. 2 is a plan view of the dispensing pipette rack 200.
As shown in FIGS. 1 and 2, the dispensing pipette rack (containment container) 200 includes a main body 210 formed in a box shape having no bottom surface. The main body 210 is integrally formed with a plurality of accommodating portions 220 capable of accommodating the dispensing pipette tip 201 or the drilling pipette tip 202, the leg portion 230, and the marker 240.

As shown in FIGS. 1 and 2, the upper surface 210a of the main body 210 is formed in a substantially square shape, and the four corners of the side surface of the main body 210 are chamfered from the viewpoint of ease of holding.

As shown in FIG. 2, the opening 222a of the second accommodating portion 222 and the marker 240 are formed at positions different from each other in the first direction (X-axis) and the same in the second direction (Y-axis). ..

FIG. 3 is a cross-sectional view taken along the line AA'perpendicular to the Y axis in the dispensing pipette rack 200 shown in FIG. In the cross section of AA', three first accommodating portions 221 are arranged in the X-axis direction.

FIG. 4 is a cross-sectional view taken along the line BB'perpendicular to the X axis in the dispensing pipette rack 200 shown in FIG. In the BB'cross section, one first accommodating portion 221 and one second accommodating portion 222 are arranged in the Y-axis direction.

As shown in FIG. 3, the first accommodating portion 221 is a substantially columnar cavity having a circular opening 221a on the upper surface 210a of the main body 210. As shown in FIG. 3, the first accommodating portion 221 is closed at the bottom surface portion (the tip portion on the opposite side of the upper surface in the Z-axis direction). The first accommodating portion 221 can easily accommodate the dispensing pipette tip 201 whose inner diameter is smaller toward the lower side in the Z-axis direction and whose outer diameter is smaller toward the tip.

As shown in FIG. 4, the second accommodating portion 222 is a substantially columnar cavity having a circular opening 222a on the upper surface 210a of the main body 210. As shown in FIG. 4, the second accommodating portion 222 has a bottom surface portion (a tip portion on the opposite side of the upper surface in the Z-axis direction) closed. The second accommodating portion 222 can easily accommodate the drilling pipette tip 202 whose inner diameter is smaller toward the lower side in the Z-axis direction and whose outer diameter is smaller toward the tip. The outer diameter of the drilling pipette tip 202 is larger than the outer diameter of the dispensing pipette tip 201. Therefore, as shown in FIG. 4, the inner diameter of the second accommodating portion 222 is larger than the inner diameter of the first accommodating portion 221.

As shown in FIGS. 3 and 4, the first accommodating portion 221 and the second accommodating portion 222 have the same length in the Z-axis direction from the upper surface 210a to the bottom surface portion of the main body 210.

The leg 230 has a first leg 231 and a second leg 232, as shown in FIGS. 3 and 4. The first leg portion 231 and the second leg portion 232 are thin plate-shaped members.
The first leg portion 231 connects two accommodating portions 220 adjacent to each other in the first direction (X-axis).
The second leg portion 232 connects two accommodating portions 220 adjacent to each other in the second direction (Y axis).

As shown in FIGS. 3 and 4, the leg portion 230 has a projecting portion 230b protruding downward in the Z-axis direction from the bottom surface portions of the first accommodating portion 221 and the second accommodating portion 222, and has a plurality of legs. The protruding portion 230b of the portion 230 forms the same plane (referred to as "bottom surface P"). The bottom surface P is parallel to the top surface 210 a of the main body 210. The dispensing pipette rack 200 can stand on its own by grounding the bottom surface P formed by the protrusions 230b of the plurality of legs 230 on a desk or the like.

As shown in FIGS. 3 and 4, the leg portion 230 is provided between the upper surface 210 a and the bottom surface P on the Z axis. Therefore, the leg portion 230 can fix each accommodating portion 220 so that the relative position of each accommodating portion 220 does not move in the entire area from the upper surface 210a to the bottom surface portion. Further, it is possible to suitably prevent the bending deformation of the elongated housing portion 220. Therefore, the dispensing pipette tip 201 and the drilling pipette tip 202 can be stably accommodated in the accommodating portion 220.

FIG. 5 is a bottom view of the main body 210 as seen from the bottom surface P side. As shown in FIG. 5, in the leg portion 230, the first leg portion 231 connects the accommodating portions 220 adjacent to each other in the first direction (X axis), and the second leg portion 232 is adjacent to the second direction (Y axis). The matching accommodating portions 220 are connected. As shown in FIG. 5, the leg portion 230 is formed only on the inside of the outermost accommodating portion 220, and is not formed on the outer side of the outermost accommodating portion 220. Therefore, when the user picks up the dispensing pipette rack 200, the legs 230 are unlikely to come into contact with the user's hand. The thin plate-shaped leg 230 can suitably prevent the user's hand from being injured.

The marker 240 is a two-dimensional code including information such as a type and an expiration date. Further, the marker 240 can also be used to prevent a mistake between the first direction and the second direction when the user handles the dispensing pipette rack 200. As shown in FIG. 2, the marker 240 is formed at a corner (upper right corner in FIG. 2) of the grid L of 3 rows and 3 columns, and is formed other than the center at the intersection of the grid L of 3 rows and 3 columns. .. The position where the opening of the accommodating portion 220 is arranged is not point-symmetrical from the center at the intersection of the grid L of 3 rows and 3 columns. Therefore, the user can recognize the first direction and the second direction by visually observing the position of the marker.

The accommodating portion 220 is not formed in the place formed on the marker 240 in the main body 210. Therefore, the user can grasp the position of the marker 240 and recognize the first direction and the second direction simply by picking up the dispensing pipette rack 200 without visually observing the marker 240. .. Further, even when the dispensing pipette rack 200 is mounted on a nucleic acid extraction device or the like, a mechanism for preventing an error in the mounting direction of the dispensing pipette rack 200 by using the characteristics of the dispensing pipette rack 200 having an asymmetrical shape.
