Description

  The present invention relates to a centrifuge rotor, a centrifuge, and a method of using the centrifuge suitable for stirring, for example, a biological sample such as sputum collected from a patient and a reagent.

In general, a tube container with a lid that is used to react or detect a target substance in a sample by stirring the sample and the reagent is known. A tube container with a lid consists of a cylindrical tube body with a tapered bottom and a lid that closes the upper opening of the tube body, and the lid can be opened and closed by a flexible hinge extending from the tube body. It is an integral structure attached to the. In the tube container with a lid, a reagent for performing reaction analysis or detection analysis at the time of contact with the sample is provided in advance, and the place to be provided is the inside of the lid, the inner peripheral surface of the tube body, or the tube There are types provided at the bottom of the main body. (See Patent Documents 1 and 2)
Both types are used by setting a tube container with a lid to a centrifuge rotor of a centrifuge for stirring when contacting a reagent and a sample. A wide variety of centrifuges are known, but especially for centrifuges made for developing countries, it is easy for anyone to operate and lowers manufacturing costs. In order to suppress this, it has become a product that has a single function and is made small and compact. An example is shown in FIG.

  In the conventional centrifuge 100 shown in FIG. 14, a centrifuge rotor 101 </ b> R is rotatably disposed in an internal space in the centrifuge body 101, and an upper portion of the internal space can be opened and closed by an opening / closing lid 102. The rotating body 103 constituting the centrifuge rotor 101R is mounted on a rotating shaft 104 that is controlled to rotate necessary for stirring. The rotating body 103 is formed in a rectangular plate shape, and both ends are bent short upward. The bent bent edge portion 105 has a simple shape in which eight round hole-shaped set holes 106 for mounting and setting the tube container 200 with a lid are provided.

  Therefore, when there is one tube container 200 with a lid, one set hole 106 is selected and used. In addition, when the multiple tube containers 200 are eight, the entire set holes 106 are used, and the bottom portion 200T of the tube container 200 is positioned in the set holes 106 from the inner side on the rotating shaft 104 side. The lid 200H is attached by being fully inserted until it hits the set hole 106.

Japanese Patent No. 5057228 Japanese Patent No. 5209990

  The above-mentioned tube container 200 with a lid is divided into a single case made by itself and a multi-tube case made by 8 stations. In a place away from the support, the connecting structure has the flexibility to hang down by its own weight, and does not have an integral rigid structure.

  For this reason, even when the multiple tube containers 200 inserted and set in the set holes 106 are removed from the set holes 106, the entire tube containers 200 can be inserted into the set holes 106 even if they are pulled in the pulling direction by holding some lids. There was a problem that it was caught and could not be removed smoothly.

  It is considered that this problem is greatly influenced by the fact that the set hole 106 is a through-hole and the tube container 200 having a multiple shape connected with flexibility. That is, when a plurality of tube containers 200 are pulled out of the set hole 106 and pulled by holding a part of the lid part 200H of the tube container 200, a pulling action of receding straight along the insertion direction is activated at that part. However, it is considered that in the region away from it, it does not work as a pulling-out action that recedes straight along the insertion direction, but acts as a resistance action in a direction in which the tube body comes into strong contact with the set hole 106. This problem is not only in terms of workability that is difficult to remove, but also has a bad influence on the analysis result due to the dispersion and adhesion of the tube container 200 after completion of stirring / reaction to the edge of the hole due to the removal impact. There was also a bug.

  In addition, the inspection accuracy may vary due to variations in stirring between the sample and the reagent, and this is preferably improved.

  Therefore, in the present invention, of course, in the case of a single tube made alone, even multiple tube containers can be easily set and removed with one hand, and variations in inspection accuracy are suppressed. It is an object to provide a centrifuge rotor, a centrifuge, and a method of using the centrifuge.

  In order to achieve the above object, a centrifuge rotor according to the present invention is a centrifuge rotor in which a tube container having a tube main body and a lid portion that can be attached to and detached from the tube main body is set. An attached horizontal member, and a holding mechanism that is provided integrally or separately with the horizontal member and holds the tube container formed in a single or multiple form, and the holding mechanism includes the tube container. When holding, the mechanism is characterized in that it can be held regardless of which direction of the lid portion is the inside of the rotation or the outside of the rotation.

  Moreover, the centrifuge which concerns on this invention is provided with the centrifuge rotor of any one of Claims 1-3.

  The centrifuge usage method according to the present invention is a centrifuge usage method using the centrifuge according to claim 4, wherein the tube container is set in the holding mechanism so that the lid portion faces the outside of the rotation. A step of rotating the centrifuge rotor, and a step of rotating the centrifuge rotor by changing the direction of the tube container held by the holding mechanism so that the lid portion faces the inside of the rotation. Features.

  According to the present invention, as a matter of course, in the case of a single tube made alone, a centrifuge rotor that can be easily set and removed with one hand even with multiple tube containers and that suppresses variations in inspection accuracy. , Centrifuges, and methods of using the centrifuges can be provided.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In the following description, the same or similar components as those already described are denoted by the same or similar reference numerals, and detailed description thereof is omitted as appropriate.

[First Embodiment]
First, the first embodiment will be described. As shown in FIG. 1, the centrifuge 1 has a centrifuge body 2 and a circular opening / closing lid 3. The centrifuge body 2 has a circular opening 2A at the top, and a centrifuge rotor 2R is rotatably arranged in the internal space of the opening 2A. The rotating body 10 constituting the centrifuge rotor 2R is attached to the rotating shaft 4 of the centrifuge rotor 2R. The rotation shaft 4 is rotationally controlled by a motor not shown in FIG. 1 (for example, the motor 8 shown in FIGS. 4 and 5) so as to perform high-speed rotation necessary for stirring the sample and the specimen. The rotating body 10 is provided with a holding mechanism 28 that holds a tube container, which will be described later, during rotation, and the holding mechanism 28 prevents the tube container from jumping upward during rotation.

  As shown in FIG. 1, on the front side of the centrifuge main body 2, an operation panel 5 is inclined, and the operation panel 5 is provided with a start button 5A and a stop button 5B. A switch 6 is provided on the upper surface of the centrifuge body 2. The opening / closing lid 3 is provided with a protrusion 3 </ b> A at a position corresponding to the switch 6. Thus, when the opening / closing lid 3 closes the opening 2A of the centrifuge body 2, the projection 3A pushes the switch 6, so that the switch 6 controls the control unit (not shown in FIG. 1) (for example, the control shown in FIGS. 4 and 5). When a signal is sent to the section 9) and the start button 5A is pressed, the start can be made. Therefore, the protrusion 3A and the switch 6 constitute a safety device that cannot start the operation of the centrifuge 1 unless the opening / closing lid 3 is closed.

  Here, before explaining an example of the structure of the centrifuge rotor 2R, an example of the shape of a multiple tube container 50 for containing a specimen will be explained with reference to FIG.

  As shown in FIG. 2, the tube container 50 is a tube container with a lid that is used to react or detect a target substance in a sample by stirring the sample and the reagent. The multiple tube container 50 includes a cylindrical tube body 52 having a tapered bottom 51, an upper opening 53 of the tube body 52, and a lid that detachably closes the upper opening 53. 54 and a surface contact portion 59 that projects from the outer periphery of the upper release port 53 and comes into surface contact with the flange portion 54R of the lid portion 54.

  The surface contact portion 59 is continuously formed so as to extend from the hinge 55 and the connecting portion 56. The lid portion 54 is attached by a flexible hinge 55 extending from the tube main body 52 so that the upper opening 53 can be opened and closed. In the example shown in FIG. 2, for example, eight tube main bodies 52 are connected in series by a connecting portion 56 that is continuous to the surface contact portion 59.

  A reagent for performing reaction analysis or detection analysis at the time of contact with the sample is placed in the tube container 50 in advance.

  Next, referring to FIGS. 3 to 5, structural examples of the centrifuge rotor 2 </ b> R described above will be sequentially described. The centrifuge rotor 2R is made of, for example, a metal plate and is attached to the upper end portion of the rotating shaft 4 that rotates at a high speed. The motor 8 is driven by a control signal from the control unit 9 in which a step program shown in FIG. 6 is incorporated. By driving the motor 8, the rotary shaft 4 can rotate at a high speed around the rotation center axis CL, for example, and can rotate by a predetermined angle clockwise and counterclockwise around the rotation center axis CL. It has become.

  The rotating body 10 includes a horizontal portion 11, a first bent portion 12 (rotating outer portion) and a second bent portion 13 (bending portion) that are bent upward so as to be disposed at both side edges of the horizontal portion 11. Rotation outer portion). The horizontal portion 11 is a rectangular flat portion, and the first bent portion 12 stands vertically from one end side of the horizontal portion 11 (90 degrees with respect to the horizontal plate 11), and the second bent portion 13. Is vertically rising from the other end side of the horizontal portion 11.

  A plurality of bottomed grooves 14 are formed along the end edge portion 12U in the end edge portion 12U (upper end portion) of the first bent portion 12. These bottomed grooves 14 are formed at regular intervals along the edge portion 12U, and the top of each bottomed groove 14 is open. In addition, the bending guide portion 15 that continues to the upper side of the first bending portion 12 is inclined outward at an angle θ as shown in FIG. That is, the forming direction S2 of the bending guide portion 15 is inclined at an angle θ with respect to the forming direction (vertical direction) S1 of the first bending portion 12. In this way, the bending guide portion 15 has a shape in which the insertion opening from above is widened by an angle θ by going obliquely upward and outward.

  In addition, a plate-like facing member 20 (rotation inner portion) disposed so as to face the first bent portion 12 (rotation outer portion) on the inner side of the rotation radius is fixed to the horizontal portion 11. The opposing member 20 is bent so as to be an L-shaped member, and includes a bent portion 22 parallel to the horizontal portion 11 and a vertical portion 24 continuous so as to be orthogonal to the bent portion 22. The bent portion 22 is fixed to the horizontal portion 11.

  In the vertical portion 24, the bottomed groove 14 is formed at a position where the groove center is the same as the bottomed groove 14 formed in the first bent portion 12. At least from the bottom to the top of the bottomed groove 14, the facing member 20 is plane-symmetric with the first bent portion 12, and the inclination direction is opposite to the bent guide portion 15 of the first bent portion 12. The bending guide portion 16 extends from the vertical portion 24 so as to be (that is, inclined at an angle θ inside the rotation).

  And the clearance gap S between the 1st bending part 12 and the opposing member 20 is the predetermined space | interval d, and the flange part 54R of the cover part 54 and the surface contact part 59 of the tube main body 52 enter this clearance gap S, and tube The container 50 is configured to be sandwiched between the first bent portion 12 and the facing member 20.

  In this configuration, when the tube container 50 is held, the lid portion 54 can be held regardless of whether the direction of the lid portion 54 is the inside of the rotation (inward of the rotation radius) or the outside of the rotation (outward of the rotation radius). Yes. In the present embodiment, the first bending portion 12 and the opposing member 20 form a holding mechanism 28 that holds the tube container 50.

  In addition, the 1st bending part 12 and the opposing member 20 may be integral with the horizontal part 11, or may be a different body. Further, the opposing member 21 disposed so as to face the second bent portion 13 on the inner side of the rotation is also fixed to the horizontal portion 11. However, since the configuration and arrangement are the same as those of the opposing member 20, the details of the opposing member 21 are described. Description is omitted. The holding mechanism 28 is also formed by the second bent portion 13 and the facing member 21.

(Function, effect)
Next, the usage example of the centrifuge 1 mentioned above is demonstrated in the example using a multiple tube container. FIG. 6 is an operation flow showing an operation example of the centrifuge 1 including the centrifuge rotor 2R of the present embodiment.

  First, as a preparatory stage, a reagent is provided in advance inside the lid 54, and a biological sample collected from a patient (patient's eyelid in the case of tuberculosis or the like) is transferred to each tube container for each patient using a pipette or the like. After putting in 50, the cover part 54 is closed and the tube container 50 is sealed. It is also possible to adopt a test method in which a reagent is not provided in the tube container 50 in advance and a reagent is inserted when a biological sample is added.

  Thereafter, as shown in FIG. 4, the multiple tube containers 50 are set in the bottomed groove 14 of the rotating body (rotor) 10. At that time, the surface contact portion 59 and the flange portion 54R are connected to the first bent portion so that the lid portion 54 of the tube container 50 faces the rotation outer side (that is, the bottom portion 51 of the tube container 50 faces the rotation inner side). The tube container 50 is sandwiched between the centrifuge rotor 2R by being inserted into the gaps S between 12 and the opposing member 20, respectively. Similarly, the multiple tube containers 50 are inserted into the gap S between the second bent portion 13 and the facing member 21.

  As a result, the flange portion 54R of each tube container 50 is in surface contact with the first bent portion 12, and the surface contact portion 59 of each tube container 50 is in surface contact with the vertical portion 24 of the opposing member 20, whereby each tube The axial direction of the container 50 is in a state (horizontal state) along the horizontal axis HL. Further, in a state where each tube container 50 is sandwiched between the gaps S, the hinge 55 of the lid portion 54 is positioned on the upper side. Similarly, the multiple tube containers 50 inserted into the gap S between the second bent portion 13 and the opposing member 21 are also held in a horizontal state along the horizontal axis HL, and the hinge 55 of the lid portion 54 is located on the upper side. Located in.

  Therefore, even if the centrifugal force F along the horizontal axis HL acts on the tube container 50 at the time of high speed rotation, the upward action of detaching the tube body 52 from the bottomed groove 14 does not occur, and the tube body 52 is reliable and stable. Can be maintained.

  Next, when the user presses the start button 5A (see FIG. 1), the operation starts based on the program of the control unit 9 (see FIG. 4). In step S1 (see FIG. 6), the centrifuge rotor 2R rotates at a low speed (for example, about 500 rpm), for example, for 30 seconds. As a result, the biological sample in the tube container 50 is fed to the reagent provided inside the lid portion 54 and the reaction generation is assisted.

  Step S2 is subsequently performed. In Step 2, the centrifuge rotor 2R rotates for 9 seconds at a speed corresponding to, for example, 2000 rpm in the counterclockwise direction within a 90-degree angle setting range. Thereby, the reagent in the tube container 50 and the biological sample are stirred and brought into reaction contact.

  In steps S1 and S2, centrifugal force F acts on the tube container 50. However, since the flange portion 54R is supported by the first bent portion 12 from the outside of the rotation, the lid portion 54 is prevented from coming off. . Further, since the tube container 50 is held horizontally, the reaction contact between the reagent and the sample is ensured.

  After step S2 ends and the rotation of the centrifuge rotor 2R stops, the user changes the orientation of the tube container 50 (step S3). In this step S3, the multiple tube containers 50 are removed from the centrifuge rotor 2R with one hand, and the centrifuge rotor is arranged so that the lid 54 faces the inside of the rotation (that is, the bottom side of the tube container 50 faces the outside of the rotation). Set to 2R. At this time, the flange portion 54R of each tube container 50 is in surface contact with the vertical portion 24 of the opposing member 20, and the surface contact portion 59 of each tube container 50 is in surface contact with the first bent portion 12, thereby each tube container. The 50 axial directions are in a state (horizontal state) along the horizontal axis HL. Further, in a state where each tube container 50 is sandwiched between the gaps S, the hinge 55 of the lid portion 54 is positioned on the upper side. The same applies to the multiple tube containers 50 inserted into the gap S between the second bent portion 13 and the facing member 21.

  Step S4 is performed after the end of step S3. In this step S4, for example, as in step S2, for example, it rotates for 9 seconds at a speed corresponding to 2000 rpm in the counterclockwise and counterclockwise directions.

  Then, step S5 is continued. In this step S5, the centrifuge rotor 2R rotates at a high speed, for example, clockwise for 6 seconds at a speed corresponding to 2000 rpm.

  Since a buzzer (not shown) sounds when the specified time (6 seconds) has elapsed (step S6), the user presses the stop button 5B shown in FIG. 1 to stop the buzzer from sounding in step S7. Then, the user takes out the multiple tube containers 50 from the centrifuge 1.

  As described above, according to the present embodiment, the centrifuge rotor 2R can hold the tube container 50 regardless of which side of the rotation inner side or the outer side of the rotation of the lid portion 54 is held. It has become. Therefore, before the reagent and the biological sample are reacted by rotating the centrifuge rotor 2R in the forward direction, the reagent and the biological sample are moved to one side of the tube container in advance by rotating in the opposite direction. Thereafter, the direction of the tube container 50 is reversed, and the centrifuge rotor 2R is rotated forward so that the reagent and the biological sample can be reacted.

  Thereby, it is not necessary to pre-stir the reagent and the biological sample by shaking the tube container 50 by hand. Therefore, even if it is shaken by hand, the reagent or biological sample is not sufficiently moved in some of the multiple tube containers 50, the inspection accuracy is lowered due to variations in the way the user shakes, Problems such as forgetting to shake the user's tube container 50 by hand do not occur.

  Of course, in the case of a single tube container 50 made independently, even a multiple tube container 50 can be easily set and removed with one hand. In addition, it is possible to greatly reduce the removal impact, which is considered to have an adverse effect on the analysis result, and a good analysis result can be obtained.

  Further, the gap S between the first bent portion 12 and the facing member 20 is a predetermined distance d, and the flange portion 54R of the lid portion 54 and the surface contact portion 59 of the tube body 52 enter the gap S, so that the tube container 50 is sandwiched between the first bent portion 12 and the opposing member 20. Therefore, the sealed state of the tube container 50 is maintained even when the centrifuge rotor 2R rotates at a high speed, and the lid portion 54 is prevented from being removed even if the lid portion 54 is positioned on the outer side of the rotation.

  In addition, the bending guide portion 15 of the first bending portion 12 is inclined outwardly at an angle θ, and the bending guide portion 16 of the opposing member 20 is inclined inwardly at an angle θ to the bottomed groove 14. The insertion opening is shaped to expand. Thereby, the operation | movement which inserts the tube container 50 to the groove bottom of the bottomed groove | channel 14 can be performed easily.

[Second Embodiment]
Next, a second embodiment will be described with reference to FIGS. The centrifuge 70 of this embodiment includes a centrifuge rotor 72R instead of the centrifuge rotor 2R of the first embodiment.

  The centrifuge rotor 72R includes a horizontal plate 71 rotated by a motor (not shown), and holding mechanisms 78P and 78Q disposed on both sides of the horizontal plate 71, respectively.

  The holding mechanism 78P includes a rotating outer portion 82 having a bottomed groove 74 (see FIGS. 8 and 10; the same configuration as the bottomed groove 14 described in the first embodiment) at the top, and a bottomed groove 74 at the top. The rotating inner portion 92 facing the rotating outer portion 82, the lower end portion of the rotating outer portion 82 and the continuous portion 84 continuing to the lower end portion of the rotating inner portion 92, and the upper portion being fixed to the continuous portion 84. A rotating shaft 86 (see FIG. 8) that is pivotally supported so as to be rotatable with respect to the horizontal plate 71 at the lower portion, and a compression coil spring 88 through which the rotating shaft 86 is inserted. With this configuration, the rotation positions of the holding mechanisms 78P and 78Q can be switched.

  Further, a bending guide portion 75 similar to the bending guide portion 15 is formed on the rotation outer portion 82, and a bending guide portion 76 similar to the bending guide portion 16 is formed on the rotation inner portion 92.

  The holding mechanism 78P is always urged upward by the compression coil spring 88. Then, the pivot shaft 86 is turned downward so that the height position is slightly lowered by being pressed downward, and the height position is slightly raised from the pivotable state by being released. It is configured to be disabled.

  Since the holding mechanism 78Q has the same configuration as the holding mechanism 78P, a detailed description of the configuration of the holding mechanism 78Q is omitted.

  In order to use the centrifuge 70 of this embodiment, first, as in the first embodiment, a reagent and a biological sample are put in a tube container 50 and sealed.

  Then, as shown in FIG. 7, the multiple tube containers 50 are provided with the bottomed grooves 74 of the respective holding mechanisms 78P and 78Q so that the lid portion 54 faces the rotation outer side (that is, the bottom 51 of the tube container 50 rotates inside). To set in the centrifuge 70. As a result, the surface contact portion 59 of the tube main body 52 and the flange portion 54R of the lid portion 54 are clamped in the gap S between the holding mechanisms 78P and 78Q (see FIGS. 7 and 8).

  Then, steps S1 and S2 are performed as in the first embodiment. After the rotation of the centrifuge rotor 72R is stopped, the user presses the holding mechanism 78P downward, reverses the holding mechanism 78P around the rotation shaft 86 (rotates 180 °), and releases the press (FIGS. 9 to 9). 11). Further, the user presses the holding mechanism 78Q downward and similarly reverses (rotates 180 °) to release the press (see FIGS. 11 to 13).

  As a result, as shown in FIG. 13, in the holding mechanisms 78P and 78Q, the multiple tube containers 50 are held so that the lid part 54 faces the inside of the rotation (that is, the bottom 51 of the tube container 50 is the outside of the rotation). become.

  And like 1st Embodiment, step S4 and subsequent are performed, and a user takes out the multiple tube container 50 from the centrifuge 70 after that.

  Therefore, according to this embodiment, when the direction of the tube container 50 is reversed, it is not necessary to pull out the tube container 50 from the bottomed groove 74. Therefore, in addition to the effects exhibited in the first embodiment, the workability of the inspection is good and the time required for the inspection can be shortened.

  In the present embodiment, when the holding mechanisms 78P and 78Q are reversed, the user can turn the holding mechanisms 78P and 78Q by pressing the holding mechanisms 78P and 78Q downward, and the holding mechanisms 78P and 78Q can be turned by releasing the pressing. Has been described in the configuration example in which it returns to its original position (upper position) and becomes unrotatable, but when the holding mechanisms 78P and 78Q are reversed, the user rotates the holding mechanisms 78P and 78Q upward. The holding mechanism 78P, 78Q may return to the original position (downward position) and become unable to rotate by releasing the lifting force.

  Further, in the present embodiment, the example in which the user directly touches and holds the holding mechanisms 78P and 78Q is described, but a lever that switches the rotation position of the holding mechanism 78P outside the centrifuge housing, and the holding mechanism The lever for switching the rotation position of 78Q may protrude. Thereby, the switching operation of the rotation positions of the holding mechanisms 78P and 78Q is simplified, and the inspection time can be further shortened.

  As mentioned above, although embodiment was described, these embodiment is an illustration for materializing the technical idea of this invention, Comprising: Material, shape, structure, arrangement | positioning, etc. of a component are specified to the said embodiment. However, various modifications can be made without departing from the scope of the invention. For example, in the first embodiment and the second embodiment, an example in which eight tube containers are used is shown as an example. However, a specification structure that can handle other than eight tubes may be used.
