DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an automatic analyzer according to the present invention will be described below in detail with reference to the drawings.

In this embodiment, as shown in FIG. 1, an automatic biochemical analyzer 1 for automatically analyzing components of a sample such as serum or urine will be described. It should be noted that the present invention is not limited to the biochemical automatic analyzer 1 exemplified here, and it is needless to say that the present invention can be applied to various devices without departing from the gist of the present invention.

The automatic biochemical analyzer 1 includes a thermostatic chamber 2 in which a plurality of test tubes accommodating samples are disposed, a first reagent storage 3 disposed adjacent to the thermostatic chamber 2, and a A second reagent storage 4 and a reaction section 5 disposed on the outer periphery of the first reagent storage 3
A first dispensing arm 6 for dispensing the reagent in the first reagent storage 3, a second dispensing arm 7 for dispensing the reagent in the second reagent storage 4, And a sampling arm 8 for dispensing the sample. Further, the automatic biochemical analyzer 1 includes a sampler cover 9 disposed so as to substantially seal the thermostat 2.

In the automatic biochemical analyzer 1, the thermostat 2 has a temperature control function for maintaining the inside at a predetermined temperature, and can maintain the inside at a desired temperature.
In addition, a sample disk 10 in which a plurality of test tubes are disposed as shown in FIG. The sample disk 10 includes a plurality of holding portions 11 having an opening shape corresponding to the outer shape of the test tube.
Are formed along the circumference. In particular, these holding parts 1
Numerals 1 are arranged concentrically on the outer circumference and the inner circumference, respectively, and are arranged in a so-called staggered manner so that the outer circumference side and the inner circumference side do not overlap. The holding portions 11 are numbered sequentially in a staggered manner. That is, when the predetermined outer holding portion 11a is set to “1”, the inner holding portion 11b adjacent to the “1” holding portion 11a is set.
Is set to “2”, and the holding portion 11c on the outer peripheral side adjacent to the holding portion 11b of “2” is numbered in order so as to be “3”.

On the side of the sample disk 10,
A notch 12 reaching each holding portion 11 is formed. For this reason, each holding unit 11 can be viewed from the side of the sample disk 10 through the notch 12.

On the other hand, the thermostat 2 in which the sample disk 10 is stored can be substantially sealed by a sampler cover 9 as shown in FIG. This sampler cover 9
Is a fixing portion 13 fixedly attached to the thermostat 2.
And a movable lid portion 14 that can be opened and closed with respect to the fixed portion 13. That is, in the sampler cover 9, the fixed part 13 and the movable lid part 14 are connected via the hinge 15.

The fixing portion 13 of the sampler cover 9
Is provided on its outer peripheral surface with a latch 16 for fixing to the constant temperature bath 2. This latch 16 is
May be formed at a plurality of places, and by being formed at the plurality of places, it is possible to more reliably fix the apparatus. Furthermore, the sampler cover 9 is provided with a hand-held portion 17 on the upper surface of the fixed portion 13 and an opening 18 formed so that the sampling arm 8 can enter. Furthermore, an engaging portion 19 for attaching to the thermostat 2 is formed on the fixed portion 13 of the sampler cover 9 on the opposite side of the latch 16.

The sampler cover 9 configured as described above
Is formed from a heat insulating material or an elastic material having good adhesion at least on the inner peripheral side. Thereby, the inside of the thermostat 2 can be sealed in a state where the sampler cover 9 is attached to the thermostat 2, and a desired temperature can be maintained. That is, by forming at least the inner peripheral side of the sampler cover 9 from a heat insulating material or an elastic material having good adhesion, the sampler cover 9 can prevent the atmosphere inside the thermostat 2 from being released to the outside and can prevent the atmosphere from being released outside. Can be prevented from entering the atmosphere.

When attaching such a sampler cover 9 to the thermostat 2, first, as schematically shown in FIG.
The latch 16 is engaged with the engagement claw 20 provided on the side surface of the thermostat 2.

Next, the engaging claws 21 provided on the outer peripheral surface of the thermostat 2 are engaged with the engaging portions 19 of the fixing portion 13. Thereby, the fixing part 13 is attached so as to securely seal the thermostat 2.

In the sampler cover 9, it is preferable that the movable lid 14 can be stopped at a predetermined position with respect to the fixed part 13. In other words, the movable lid 1
4 is preferably connected to the fixed part 13 via a hinge 15 having a lock mechanism such as a free stop hinge. Through the hinge 15 having such a lock mechanism, the movable lid 14 can maintain the position at a predetermined angle with respect to the fixed part 13, and the constant-temperature bath 2
Is prevented from moving in the closing direction.

By the way, such a sampler cover 9
By detaching the latch 16 from the engaging claw 20 after detaching the engaging claw 21, the can be easily removed from the thermostatic bath 2. Specifically, first, after removing the engagement claw 21,
The fixing portion 13 is rotated in the direction indicated by the arrow a in FIG. 5, and then the entire sampler cover 9 is moved in the direction indicated by the arrow b in FIG. As described above, the above-mentioned sampler cover 9 can be very easily detached from the thermostat 2.

In the biochemical automatic analyzer 1 configured as described above, the thermostat 2 is sealed by the sampler cover 9, and the inside of the thermostat 2 is maintained at a predetermined temperature. Then, the test tube held on the sample disk 10 in the thermostatic bath faces from the opening 18 formed in the sampler cover 9. For this reason, the sampling arm 8
Is inserted into the opening 18 so that a sample in a test tube facing the opening 18 can be sampled.

The sample disk 10 is rotated at a predetermined speed in the thermostat 2 because it is necessary to sequentially access the test tubes from the opening 18. At this time,
As described above, the sample disk 10 has the holding portions 11 formed in a staggered manner, and has a plurality of test tubes held by these holding portions 11.

In this sample disk 10, since the test tubes are held in a staggered manner and the cutouts 12 are formed in the respective holding portions 11, when the test tubes to which a barcode is attached are used, the sample disks 10 The sample disk 10 is set to 1 by the barcode reader arranged on the side.
During the rotation, the barcodes of all the test tubes can be read in the numerical order given to the holding unit 11.

Further, in the biochemical automatic analyzer 1,
When the test tube held on the sample disk 10 is replaced, the movable lid 14 of the sampler cover 9 is moved to release the inside of the thermostat 2. That is, in the automatic biochemical analyzer 1, the test tube can be replaced while the sampler cover 9 is opened halfway, so that the change in the atmosphere in the thermostat 2 can be minimized. For this reason, according to this automatic biochemical analyzer 1, the temperature change in the thermostat 2 can be reduced, and the time from when the sampler cover 9 is closed until measurement becomes possible can be shortened. Can be reduced to maintain the temperature at the condition temperature.

In the automatic biochemical analyzer 1, when replacing or refilling a test tube, work can be performed with the sampler cover 9 attached to the sample disk 10. Therefore, the sampler cover 9 is removed and the sampling arm 8 and the like are removed. The danger of hitting other parts or dropping on a sample or reagent can also be prevented. Further, it is possible to prevent a danger that the sampler cover 9 removed during the operation is difficult to be placed or that the temporarily placed sampler cover 9 is inadvertently damaged.

Further, if necessary, the sampler cover 9 can be removed from the thermostat 2 by removing the fixing portion 13 of the sampler cover as described above. For this reason, when the constant temperature bath 2 and the sample disk 10 are maintained, the operability is excellent.

In the automatic biochemical analyzer 1, the sampler cover 9 is fixed to the fixed portion 13 and the movable lid portion 1 via the hinge 15 having the lock mechanism as described above.
4, the movable lid 14 can be stopped at a desired position. Therefore, when the movable lid 14 is manually rotated to release the inside of the thermostat 2, it is prevented that the movable lid 14 pivots in a direction of closing the thermostat 2 by its own weight. You. This biochemical automatic analyzer 1
Has excellent safety when opening and closing the constant temperature bath 2, for example, it is possible to prevent the danger of the operator being caught in the work, and the movable lid 14 is provided with the sampling arm 8 and the like. Accidents that would cause damage can be prevented.

In the automatic biochemical analyzer, the test tubes held in the holders (sample discs) are exchanged and replenished as necessary in the order of the numbers (measurement order) assigned to the holders. There is a biochemical automatic analyzer 1
The sample disks 10 are sequentially numbered in a staggered manner with respect to the holding portions 11 arranged in a staggered manner as described above. For this reason, when the movable lid portion 14 is rotated to bring the thermostatic chamber 2 to the half-open state and substantially half of the sample disk 10 is exposed outward, as shown in FIG. The held holding portion 11 is exposed. Specifically, in the sample disks 10 numbered in order from "1" to "24", the holding portions 11 of "1" to "12" are exposed. By rotating the sample disk 10 approximately half a turn, the sample disk 10 shown in FIG.
As shown in (2), the holding portions 11 of "13" to "24" are exposed. In FIG. 6, the hatched portion on the sample disk 10 indicates a region that is covered with the fixing portion 13 and is not exposed to the outside.

On the other hand, in the conventional sample disk 50 as shown in FIG.
1 are sequentially numbered, and the subsequent numbers are taken over by the holding units 52 arranged on the inner peripheral side and sequentially numbered.
Specifically, when the conventional sample disk 50 is used, “1” to “6” are exposed in the state shown in FIG.
In the state shown in (b), “7” to “12” are exposed. Next, the sample disk 50 is rotated substantially half a second time again, and FIG.
In the state shown in (c), "13" to "18" are exposed, and then the sample disk 50 is further rotated substantially half a second time to expose "19" to "24" as shown in FIG.

As described above, the conventional sample disk 50
Is used, it is necessary to rotate the sample disk 50 approximately two times in order to expose the holding portions 51 of “1” to “24” in numerical order. Therefore, when such a sample disk 50 is used, it becomes very troublesome work to replace the test tubes in the order of the numbers given to the holding unit 51, and a replacement error is likely to occur.

On the other hand, in the automatic biochemical analyzer 1, as shown in FIGS. 6 (a) and 6 (b), only one rotation of the sample disk 10 The test tubes can be sequentially and sequentially replaced in the numbered order (or measurement order). As described above, the biochemical automatic analyzer 1 described above can easily recognize the position of the test tube to be replaced, as compared with the case where the conventional sample disk 50 is used, so that the occurrence of a replacement error can be reduced. Can be prevented, and the work efficiency is greatly improved.

The automatic biochemical analyzer according to the present invention is not limited to the configuration having the sampler cover 9 as described above. That is, the biochemical automatic analyzer shown as another embodiment is shown in FIGS.
As shown in (1), a configuration having a sampler cover 25 fitted to the thermostat 2 may be employed.

The sampler cover 25 has an inner diameter substantially the same as the outer diameter of the thermostat 2, and has a movable lid 27 rotatably disposed with respect to a fixed portion 26. Further, on the side surface of the sampler cover 25, an engagement protrusion 28 that engages with the engagement claw 21 of the thermostat 2 is formed.

The sampler cover 25 thus configured
Is fixed to the constant temperature bath 2 by being fitted in the constant temperature bath 2 and engaging the engaging claws 21 with the engaging projections 28. At this time, the sampler cover 25 is
6 is fitted to the thermostat 2 at a predetermined depth,
Even if there is no fixing means for the movable lid 27, the thermostat 2 can be securely sealed. In other words, the sampler cover 25 can be easily removed from the constant temperature bath 2 simply by removing the engaging claw 21 and lifting it upward.

In such a sampler cover 25 as well, the movable lid portion 27 can be rotated to expose the inside of the thermostatic bath 2 to the outside. Therefore, this sampler cover 2
5, the change in the atmosphere inside the thermostat 2 can be suppressed as much as possible. In addition, since the test tubes can be replaced or refilled without removing the entire sampler cover 25, the workability is excellent.

The automatic biochemical analyzer 1 according to the present invention.
Then, a configuration having a sampler cover 30 as shown in FIG. 11 may be employed. This sampler cover 30
Is provided with a plurality of bar-shaped engaging protrusions 31 on the inner peripheral surface. The sampler cover 30 has an inner diameter that is substantially the same as the outer diameter of the thermostatic chamber 2.
A movable lid portion 33 is provided so as to be rotatable with respect to 2.
When this sampler cover 30 is used, a plurality of engagement grooves 34 that engage with the engagement protrusions 31 need to be formed on the outer peripheral surface of the constant temperature bath 2.

The sampler cover 30 thus configured
After accurately positioning the engagement protrusion 31 and the engagement groove 34 of the thermostat 2, it is moved into the thermostat 2 in the direction indicated by the arrow a in FIG. Thereafter, the sampler cover 30 is rotated in the direction indicated by the arrow b in FIG.

The sampler cover 30 has an engaging projection 31
And the engaging groove 34 are engaged with each other, so that it is securely attached to the constant temperature bath 2, so that other fixing means is not particularly required. For this reason, the sampler cover 30 has a relatively simple structure and has improved operability.

Also in such a sampler cover 30, the inside of the thermostat 2 can be exposed outward by rotating the movable lid portion 33. Therefore, this sampler cover 3
Even when 0 is used, the change in the atmosphere inside the thermostat 2 can be suppressed as much as possible. Further, the test tubes can be replaced or refilled without removing the entire sampler cover 30, so that the workability is excellent.

Further, the automatic biochemical analyzer 1 according to the present invention may have a configuration having a sampler cover 40 as shown in FIG. This sampler cover 40
Has a configuration in which a portion 41a of the fixed portion 41 that is in contact with the thermostat 2 is made of a magnetic material, and a movable lid portion 42 is rotatably connected to the fixed portion 41. When this sampler cover 40 is used, it is preferable that the portion 43 of the constant temperature bath 2 that is in contact with the fixing portion 41 is also made of a magnetic material.

In the biochemical automatic analyzer 1 configured as described above, the fixing part 41 and the thermostatic bath 2 come into close contact with each other by magnetic force.
The sampler cover 40 will be attached to the thermostat. In this case, simply by placing the sampler cover 40 on the thermostat 2, the fixing portion 41 can be securely fixed,
The simplification of the sampler cover 40 can be achieved.

Also in such a sampler cover 40, the movable lid 42 can be rotated so that the inside of the thermostat 2 can be exposed to the outside. Therefore, this sampler cover 4
Even when 0 is used, the change in the atmosphere inside the thermostat 2 can be suppressed as much as possible. In addition, since the test tubes can be replaced or refilled without removing the entire sampler cover 40, the workability is excellent.

Further, the automatic biochemical analyzer 1 according to the present invention may have a configuration having a sampler cover 60 as shown in FIG. The sampler cover 60 is fixed to the fixed portion 6 which is fixedly attached to the thermostat 2.
1 and a movable lid portion 62 which is arranged to be openable and closable with respect to the fixed portion 61.

On the outer periphery of the fixing portion 61, a latch 63 for fixing to the constant temperature bath 2 is provided. The latch 63
There may be a plurality of locations on the outer periphery of the fixing portion 61. The fixing portion 61 is fixed to the constant temperature bath 2 by engaging the latch 63 with the engaging portion 20 provided on the side surface of the constant temperature bath 2.

When the movable lid 62 is opened, the floating of the fixed portion 61 is suppressed by the fixing of the engaging portion and the weight of the fixed portion 61. When the movable lid 62 is closed, the engaging claws 21 disposed on the outer peripheral surface of the thermostat 2 engage with the engaging portions 64 at the distal end of the movable lid 62. Thereby, both the fixed part 61 and the movable lid part 62 are attached so as to securely seal the thermostat 2.

Also in such a sampler cover 60, the movable lid 62 can be moved to expose the inside of the thermostatic bath 2 to the outside. Therefore, this sampler cover 60
Even when using, the change in the atmosphere inside the thermostat 2 can be suppressed as much as possible. In addition, since the test tubes can be replaced or refilled without removing the entire sampler cover 60, the workability is excellent.

In the present invention, the means for fixing the fixing portion of the sampler cover and the thermostatic bath is not limited to the above-mentioned one, but may be a fixing means using screws, magic tape, hooks or the like. Is also good. Further, the fixing means can be released as necessary, so that the entire sampler cover can be removed. For example, if a method of releasing a hook by pressing a push button as a fixing means is adopted, the entire sampler cover can be easily removed without using a tool.

The automatic analyzer according to the present invention is preferably provided with a sensor for judging the open / closed state of the movable lid on the sampler cover side or the thermostat side. In this case, when the movable lid is open and the thermostatic bath is exposed to the outside, the sensor detects the opening of the movable lid and the biochemical automatic analyzer 1
Is controlled so as to stop the measurement operation.

That is, the control is performed so that the movement of the sample disk, the arm, and the test storage is stopped. If the movable lid is opened for replacement etc. while reading the barcode attached to the test tube held in the thermostat, the sensor detects the opening of the movable lid and reads the barcode. Controlled to stop. Then, after the sensor detects that the movable lid has been closed, the bar code reading is continuously performed from the time when the reading of the bar code is stopped, or the reading is performed again from the beginning. As a result, the automatic analyzer can reliably prevent a malfunction and improve the reliability.

Finally, the above embodiment is only one example of the present invention. For this reason, the present invention is not limited to the above embodiment. For example, in the description of the above-described embodiment, the description has been limited to the sample thermostat.
The same can be applied to a thermostatic bath for keeping the reagent cool. In addition, it is a matter of course that various changes can be made according to the design and the like within a range not departing from the technical idea according to the present invention.
