Description
Technical Field
The present invention relates to a device and method for mixing a sample using a capless tube.
Background
There are many clinical immunoassay apparatuses using a blood collection tube (blood collection tube) that contains blood collected from a patient in a hospital. Mainly is a device for separating plasma and corpuscles from blood contained in a blood collection tube by centrifugal separation and then collecting only the plasma for examination.
However, since the examination time is long and the method of separating the test sample is complicated, many clinical immunoassay apparatuses using whole blood directly have been proposed. When the whole blood collected in the blood collection tube is allowed to settle for a certain period of time (about several minutes), the blood plasma floats upward due to the high-density blood cells, and depending on the collection time and the collection interval of the sample contained in the blood collection tube, an error occurs in the collection process of the target protein to be used. In order to solve such a problem, when a diagnosis is made using blood in a blood collection tube, the blood is artificially mixed and used.
The blood collection tube stores blood in a state of being covered with a rubber cap, and when blood collection is required, blood collection is realized by pricking a needle of a syringe into the cap. Before blood is collected from the blood collection tube, the blood in the blood collection tube is mixed by the blood mixing device as described above.
In fig. 1, (a), (b), (c), and (d) show a general blood mixing device, and as shown in (a) and (b), the blood is mixed by performing a rotational motion or a vibration motion within a predetermined angle range in a state where the blood collection tube is laid on the upper portion of the tray, or as shown in (c), the blood collection tube is rotated in the vertical direction, or as shown in (d), the blood collection tube is fixed in a scattering state on the tray which is rotated, and the mixing of the blood is realized.
However, such a series of processes of mixing blood in a state where the blood collection tube is capped and collecting the blood by the needle for collecting the test sample is hardly applicable to an automated analysis apparatus.
Specifically, when a sample is collected in an automatic sample analyzer, a long needle is inserted into a cap of a blood collection tube to collect the sample, and in this case, a syringe needle that has been used for collecting the sample once is contaminated and must be cleaned.
Therefore, the present inventors have developed a sample mixing device that facilitates automation of sample analysis and collection by using a cap-less tube to eliminate a separate syringe needle and accompanying peripheral equipment when automating the sample collection process.

The present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, the sample mixing device of the present invention includes: a clamp part 110 supporting the uncovered tube 10 such that the uncovered tube 10 stands upright and performs a rotation motion; and a driving part 120 generating a driving force for the rotation motion of the cap-less pipe 10.
The tube used in the present invention is a cap-less tube 10 having no cap at the upper end opening, and in this case, the sample may be a liquid sample such as a whole blood sample, or may be a mixture of a liquid and a solid.
The clamp portion 110 includes: a rotary plate 113 having a placement groove 111 formed on an upper surface thereof and a rotary shaft 112 inserted with a shaft at a lower end thereof; and a bearing 114 supporting the rotation shaft 112 such that the rotation shaft can freely rotate.
The placing groove 111 may be a curved groove having the same curvature as the curved surface of the lower end of the pipe 10 or a slightly larger curvature radius so that a portion of the lower end of the pipe 10 can be inserted therein, and at this time, a guide member supporting the side of the uncovered pipe 10 may be provided so that the uncovered pipe 10 maintains the standing state.
In addition, since the placement groove has a sufficient depth, the uncovered pipe can be self-standing without the aid of additional guide members and be positioned in the placement groove.
The driving part 120 is provided at the upper end of the uncovered pipe 10 to be movable up and down, and specifically, may include: a fixing head 121 fixing and supporting an upper end of the uncovered pipe 10; and a driving source 122 that rotates and drives the fixing head 121.
In fig. 2, an additional driving source for elevating and lowering the driving part 120 in the up and down direction and a guide device for guiding the moving direction thereof are provided, which will be described again with reference to the drawings.
The driving source 122 may be any of various known electric motors, and a driving force transmission device, such as a gear or a belt, for transmitting a driving force may be additionally provided between the fixed head 121 and the driving source 122.
A fixing hole 121a for receiving the upper end of the cap-less pipe 10 is formed at the lower end surface of the fixing head 121, and preferably, a guide surface 121b formed to be obliquely expanded from the fixing hole 121a is formed so that the upper end of the cap-less pipe 10 can be correctly placed in the fixing hole 121a along the guide surface 121b of the fixing head 121.
Preferably, a friction pad 123 may be provided on the bottom surface of the fixing hole 121a, and a contact surface of the friction pad 123 with the capless pipe 10 has a large friction force, so that the capless pipe 10 can be prevented from slipping (slip) during the rotational movement of the fixing head 121, and the rotational movement of the fixing head 121 can be correctly transmitted to the capless pipe 10.
The respective rotation shafts of the grip part 110 and the driving part 120 are provided on the same axis C on which the cap-less tube 10 performs a rotation motion, thereby achieving mixing of the sample.
Fig. 3 (a), (b), (c), and (d) are diagrams for explaining an operation example of the sample mixing device of the present invention.
Referring to fig. 3 (a), the cap-less tube 10 containing the specimen is placed on the upper portion of the clamp part 110, and then the driving part 120 descends and abuts against the cap-less tube 10 to fix the upper end.
Preferably, the driving part 120 rotates at a low speed while descending, so that the capless pipe 10 can be fixed.
When the cap-less pipe 10 is placed on the upper portion of the clamp part 110, there is a possibility that it does not completely coincide with the direction of the rotation axis, and in the present invention, as the driving part 120 is rotated at a low speed while being lowered, the upper end of the cap-less pipe 10 is brought into contact with the inclined guide surface 121b and is naturally and precisely placed in the fixing hole 122 along the rotation axis of the rotating driving part 120, thereby achieving fixing.
The rotation speed of the driving unit 120 generated when the driving unit 120 is lowered may be appropriately determined in a range lower than the rotation speed of the uncovered tube 10 during sample mixing.
Then, as shown in fig. 3 (b) and (c), the rotation of the cap-less tube 10 by the rotation of the driving part 120 may be a rotation in one direction or a rotation in a clockwise or counterclockwise direction at predetermined intervals, so that the sample is mixed.
As shown in fig. 3 (d), after the sample is mixed, the driving part 120 is raised and returned to the original position, so that the sample collection and analysis work in the cap-less tube 10 can be performed.
Fig. 4 (a) and (b) are photographs showing the state before and after mixing by rotating (spinning) the blood in each tube under a predetermined condition, (a) is a photograph taken of the tube before mixing, and (b) is a photograph taken of the tube after rotating the tube at a rotation speed of about 6000RPM for 35 seconds.
In fig. 4 (b), reference numeral'd' represents the maximum liquid level difference of blood due to centrifugal force when the tube rotates (spins), and it is known that the liquid level difference is not so large because the liquid level difference is within about 1cm in a general rotation (spinning) speed range (several cm) in which blood can be sufficiently mixed, and therefore, even if the sample is mixed by rotating the capless tube, the mixing device of the present invention can mix the sample without overflowing during the mixing process.
