Description

[Detailed description of the invention] (Field of industrial application) The present invention is a shaking method that applies shaking to a sample liquid such as blood contained in a container such as a test tube, a sample bottle, or a flask. Regarding equipment.

(Prior art) Generally, when testing collected blood, if the blood is left as it is, it will clot and the test cannot be performed, so the blood and anticoagulant are placed in a container such as a test tube for about 20 minutes. It is necessary to stir for about a minute to prevent blood from coagulating.

BACKGROUND ART Conventionally, agitation of a sample liquid such as blood has been automatically performed using a shaking device, and a known shaking device has a structure shown in FIG. 5.

That is, the shaking device includes a pedestal 13 and a pedestal 1.
a drive motor 14 rotatably supported by 3;
It is composed of a rotating disk 16 attached to a rotating shaft 15 of a drive motor 14, and the rotating disk 16
A clamp 18 is attached to which can securely hold a container 17 such as a test tube.

A container 17 such as a test tube containing a sample liquid such as blood is fixedly held by the clamp 18 of the rotating disk 16, and by rotating the rotating disk 16 at a predetermined rotational speed, the sample in the container 17 is removed. The liquid can be stirred. Furthermore, by replacing the rotating disk 16, it is possible to hold containers 17 other than test tubes, such as sample bottles and French bottles, and it is also possible to stir the sample liquid contained in these containers.

In particular, this shaking device is capable of handling containers 17 such as test tubes.
Since the tube repeatedly falls and stands up, it has the advantage that the sample solution can be stirred efficiently.

However, the above-mentioned shaking device has a configuration in which the rotating disk 16 is fixed to the rotating shaft 15 of the drive motor 14 by a hinge 19 or the like, and the rotational force of the rotating shaft 15 is applied to the rotating disk 16, so that the rotating disk 16 is not rotated. There is a problem in that it takes time to attach and detach the rotary disk 16 to and from the shaft 15, and the rotary disk 16 cannot be replaced simply and easily. In particular, if the rotating disk 16 is fixed to the rotating shaft 15, if the rotating disk 16 collides with another object while rotating, it may be overloaded and partially damaged, or There is a risk that the container 17 may be damaged. However, if the user's clothes or the like are caught in the rotating disk 16 while the rotating disk 16 is rotating, it is extremely dangerous and poses a serious safety problem.

In addition, since the container 17 such as a test tube is fixedly held by the clamp 18 of the rotating disk 16,
A large number of clamps 18 must be attached to the rotating disk 16, which increases the number of parts, complicates assembly, and increases costs.

Furthermore, the clamp 18 of the rotating disk 16
Since the container 7 has a strong holding force so that it does not easily come off, there is also the problem that the container 17 cannot be attached and removed easily and efficiently.

(Problems to be solved by the invention) The present invention was devised in order to solve each of the above-mentioned problems, and its purpose is to easily and easily attach and detach the rotating disk, and also to improve safety. excellent,
It is an object of the present invention to provide a shaking device in which the number of parts can be reduced and a container can be easily and efficiently attached to and removed from a rotating disk.

(Means for Solving the Problems) The shaking device of the present invention consists of a drive motor installed in the case body, and a rotating shaft that is attached to the rotating shaft of the drive motor to fixedly hold a container containing a sample liquid. In a shaking device equipped with a disc, the driving motor is tilted so that its rotating shaft takes a predetermined elevation angle, and a friction plate is attached to the rotating shaft,
The rotary disk is characterized in that a recess into which the container can be fitted and held is formed, and the rotary disk is removably attached to the rotating shaft of the drive motor or the friction plate so that the back surface thereof contacts the friction plate. There is.

(Function) When using the above-mentioned shaking device, a rotating disk is fitted to the rotating shaft of the drive motor or a friction disk, a container containing a sample liquid is fitted into the recess of the rotating disk, and the shaking device is driven. drive the motor for Then,
The rotating disk rotates at a predetermined rotational speed in an inclined state due to the frictional force with the friction plate. As a result, the container repeatedly falls and stands up, and the sample liquid in the container is well and reliably stirred. Moreover, by replacing the rotating disk, it is also possible to stir sample liquids contained in containers of other shapes.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a partially cutaway side view of a shaking device according to an embodiment of the present invention, and the shaking device is composed of a case body 1, a drive motor 2, a friction plate 3, a rotating disk 4, etc. ing.

The case body 1 has a substantially box shape,
A rack 6 on which a container 5 such as a test tube is placed is provided on both side walls. Although not shown,
The case body 1 is provided with a handle for easy carrying.

The drive motor 2 is installed in an inclined state within the case body 1 so that its rotation shaft 7 takes a predetermined elevation angle, and the rotation shaft 7 projects outward from the front wall of the case body 1. It's summery. In this embodiment, a variable speed motor is used as the drive motor 2, and the rotational speed of the rotating shaft 7 can be varied as appropriate.

The friction plate 3 is made up of a metal disc 8 having a shaft portion 8a formed in the center and a rubber disc 9 attached to the metal disc 8, and is fixed to the rotating shaft 7 of the drive motor 2.

On the other hand, the rotary disk 4 has a recess 10 into which a container 5 such as a test tube can be fitted and held, and the rotary shaft 7 of the drive motor 2 or the friction plate 3 is in contact with the friction plate 3 on the back surface thereof. It is removably attached to the

That is, in this embodiment, as shown in FIGS. 3 and 4, the rotating disk 4 is made of synthetic resin and has a thick wall, and a container 5 such as a test tube can be fitted and held on the surface of the rotating disk 4. The recesses 10 are formed radially, and a through hole 11 is formed in a part of the recesses 10 so that the container 5 inside the recesses 10 can be easily taken out. Further, in this embodiment, the rotary disk 4 is detachably attached to the friction plate 3 so that its back surface comes into contact with the friction plate 3, and the shaft portion of the friction plate 3 is attached to the center of the rotary disk 4. By drilling a fitting hole 12 that fits into the friction plate 8a, the friction plate 3 can be fitted and removed. The size of the recess 10 is set to match the outer shape of the container 5 or to be slightly larger than the outer shape of the container 5.

Therefore, when using the above-mentioned shaking device,
First, the shaft portion 8a of the friction plate 3 is fitted into the fitting hole 12 of the rotary disk 4, and the back surface of the rotary disk 4 is inserted into the friction plate 3.
bring it into contact with. Note that the rotational force of the rotating shaft 7 of the drive motor 2 can be transmitted to the rotating disk 4 simply by fitting the fitting hole 12 of the rotating disk 4 into the shaft portion 8a of the friction plate 3. This is because the rotating shaft 7 of the drive motor 2 is inclined upward, and the friction plate 3 and the rotating disk 4 are in contact with each other.

Next, a test tube containing a sample liquid such as blood is fitted into the recess 10 of the rotating disk 4.

Then, the drive motor 2 is driven to rotate the rotating shaft 7 at a predetermined rotational speed. Then, the rotating disk 4 rotates in an inclined state due to the frictional force with the friction plate 3. As a result, the test tube is repeatedly overturned and stood up, and the sample solution is well and reliably stirred.
Incidentally, since the rotary disk 4 rotates in an inclined state, the test tube never falls out of the recess 10.

On the other hand, after stirring the sample liquid, the rotation of the rotary disk 4 is stopped, and a finger is inserted into the through hole 11 of the recess 10 to push out the test tube. Thereby, the test tube can be easily taken out from the recess 1.

In the above embodiment, the rotating disk 4 is formed thick and the recess 10 is formed on its surface, but in other embodiments, the rotating disk 4 is formed of a thin plate. and partially hollow the surface to create a recess 1.
0 may be formed.

Further, in the above embodiment, the recess 10 of the rotary disk 4 was formed in a shape capable of fitting and holding a test tube, but the shape of the recess 10 is not limited to that of the above embodiment. Instead, it may be formed into a shape that can fit and hold containers such as sample bottles, flasks, and beakers.

Furthermore, in the above embodiment, the rotating disk 4 was attached to the friction plate 3 in a detachable manner, but in other embodiments, the rotating disk 4 was attached so that its back surface was in contact with the friction plate 3. It may also be detachably attached to the rotating shaft 7 of the drive motor 2.

In addition, in the above embodiment, the driving motor 2 is stopped when attaching the test tube to the rotating disk 4 or when removing the test tube from the rotating disk 4, but it is not necessary to stop the driving motor 2. It is also possible to perform the above operations without any need. This is because, since the drive motor 2 and the rotating disk 4 are frictionally transmitted, only the rotation of the rotating disk 4 can be stopped.

(Effects of the invention) Since the present invention has the above configuration, it has the following advantages.

(1) A structure in which a friction plate is attached to the rotating shaft of the drive motor, and a rotating disk capable of holding a container is detachably attached to the rotating shaft of the drive motor or the friction plate so that its back side contacts the friction plate.
