吸引され、測定部へ供給される。 BACKGROUND ART Currently, blood test devices are known that measure red blood cell counts, white blood cell counts, platelet counts, red blood cell pigment concentrations, hematocrit values, etc. with good reproducibility and high accuracy using a combination of laser technology and computer technology. When testing blood with such a test device, a test tube containing blood is placed at the measurement sample set position of the test device, and the sample in the test tube is aspirated by an aspirator extending from the test device, and the sample is then measured. supplied to the department.

やさなければならないという問題があつた。 By the way, when blood as a specimen is supplied to this blood test apparatus, the blood in the test tube immediately before being sucked by the aspirator needs to be kept in a uniform suspended state. For this reason, in the past, inspectors had to shake the bottoms of test tubes with their hands to stir the test tubes. However, such manual stirring operations result in large variations in the stirring conditions for each test tube, making it impossible to achieve uniform stirring, and it is difficult to obtain a good suspension state without destroying red blood cells, white blood cells, etc. The drawback was that it required considerable skill to perform proper stirring. Furthermore, with such manual stirring operations, apart from when conducting an emergency blood test, hundreds of specimens must be processed when the blood of a large number of patients is tested at any time at a hospital, etc. In such cases, there is a problem in that a large number of inspectors and their considerable effort and time must be spent on the stirring work.
従つて、本発明の目的は、試験管底部を振つて
該試験管内部の試料を撹拌する装置を提供するこ
とにある。 Therefore, an object of the present invention is to provide an apparatus for stirring the sample inside the test tube by shaking the bottom of the test tube.

It is attached so as to cover the open side of the holding member. Since this protective cover 40 is only for preventing the holder 34 from falling off from the holding member 35, it has a height dimension that is slightly longer than approximately half the height of the holding member 35, and has a height dimension that is slightly longer than approximately half the height of the holding member 35, and its lower end It is attached to the holding member 35. That is,
A hole 41 formed across the bottom wall 35c of the holding member 35 is a hole 41a having a larger diameter by a certain length from the support member 36 side, and from this, the side wall 35b
A small diameter hole 41b is formed into the hole 41b. A coiled spring 42 is inserted into this large diameter hole 41a, and the mounting rod 4 is inserted through the inner space of this spring 42.

The other end can enter into the large diameter hole 41a, but
In this case, a large-diameter head is provided to compress the spring 42 from its end. As a result, the protective cover 40 always tries to maintain the attached state as shown in FIG. 6 due to the elastic force of the spring 42, and the protective cover 40 is pushed from the side wall 35b side as shown in FIG. By pulling it out, the open side of the holding member 35 can be opened.

ぞれ相反する方向に回転する。 Thereafter, when the motor 20 is started, the rotation of the motor is transmitted to the shaft 22 via the reduction gear train 21, thereby rotating the disk 24. As the disc 24 rotates, the shaft 25 attached to the eccentric position of the disc 24 rotates (revolutions) around the central axis of rotation of the disc 24 and meshes with the stationary gear 23 due to this revolution. Gear 26 at the lower end of the shaft 25
rotates, and this shaft 25 also rotates (rotates on its own axis).
As a result, as shown in FIGS. 4 and 5, the slidably supported unit 12 is
It is caused to reciprocate by cranking the actuating rod 27. At the same time, the rotation of the shaft 25, that is, its rotation, is transmitted to the roller 11a via the pulleys 29, 30 and the rubber belt 31. The rotation of this roller 11a is transmitted to the other roller 11b via gear trains 15a to 15d in the unit 12, and
As described above, the two rollers 11a and 11b rotate in opposite directions.

As a result, as shown in FIG. 3, the test tube 32, whose head is positioned between the rollers 11a and 11b and is swingably supported, is moved to the side by each roller 11a and 11b each time the unit 12 moves back and forth. The holder 34 is pushed down toward the
And the holding member 35 is swung about the pin 37 as a pivot. At this time, each time the test tube 32 makes contact with each of the rollers 11a and 11b alternately, the test tube 32 receives a rotational force due to frictional engagement with the rollers and rotates within the holder 34. This test tube 3
2, the rotation of each roller 11a, 1 as described above.
Since the rotation directions of the rollers 1b are opposite to each other, the directions are reversed each time the rollers in contact change. Therefore, the test tube 32 also rotates forward and backward while swinging. At this time, test tube 32
Since the swing fulcrum (the position of the pin 37) is located above half of the height of the test tube, the bottom of the test tube in particular swings significantly. As a result, the blood in the test tube 32 is stirred into a good suspended state without destroying red blood cells, white blood cells, etc., and there is no variation between test tubes.

る。 In the stirring device 10 of the embodiment described above, the test tube is oscillated by the reciprocating motion of the two rollers 11a and 11b in the alignment direction, but the present invention is not limited to this. For example, as in another embodiment shown in FIG.
At least two rollers 5b are arranged in a staggered manner and these rollers are rotated in opposite directions, and then the device 33 that swingably supports the test tube is advanced to move the head of the test tube onto the rollers 45a and 45b. A similar effect can be obtained by making them contact each other alternately.

It can be anything. Another example of the holder 46 shown in FIG.
It is U-shaped with upper and lower overhangs 47a and 47b, respectively, with the upper overhang 47a having an opening 48 into which a test tube can be loosely inserted, and the lower overhang 47b receiving the bottom of the test tube. A dish-shaped recess 49 is formed for this purpose. Such a holder 46 has the advantage that the test tube can be rotated smoothly because there are very few contact parts between the test tube and the holder.
