[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood test performed by a blood test apparatus at a blood center or a hospital.
The present invention relates to a titration plate cleaning device that cleans a titration plate used to divide a specimen into small units for each test item for reuse after the end of the test.

[0002]

2. Description of the Related Art A conventional apparatus for cleaning a titration plate after use in a blood test apparatus usually has a structure as shown in FIG.
As shown in FIG. 5, a supply rack c in which a titration plate b to be cleaned is loaded in parallel on the upper surface side of the machine body a formed in the shape of a pedestal, and at a portion closer to one side in the left-right direction of the machine body a.
Is installed on the floor surface of the titration plate b ...
A conveyor device (not shown) that sequentially conveys the sheets toward the rear (upward in FIG. 1), and is installed in the supply rack c at a portion closer to the rear on the upper surface side of the machine body a. Therefore, a transfer device d for transferring out the titration plate b sent to the rear end portion of the supply rack c and transferring it to the other side in the left-right direction is provided, and in the middle of its transfer path,
A cleaning head e equipped with a cleaning nozzle for spraying cleaning water is provided on the titration plate b to be transferred, and the cleaning head is carried out from the supply rack c by the transfer device d on the other side in the left-right direction of the machine body a. A collection rack f for collecting the washed titration plates b by passing e is installed, and the titration plates b sent by the above-mentioned transfer device d are sequentially mounted on the floor surface of the collection rack f. It is configured by installing a conveyer device (not shown) that conveys it to the front in f.

[0003]

In the titration plate cleaning device for cleaning the titration plates b ... Used for the blood test in the blood test device so as to use them again for the test, the titration plate b is loaded in the supply rack c. A conveyor device is required for sequentially moving the plates b ... to the recovery rack f through the cleaning head e and moving them to the recovery rack f.
Since a conveyor device is required for sequentially moving the received titration plates b to the receiving position from the transfer device d so as to open the receiving plate, the structure of the supply rack c and the recovery rack f is complicated. There is a problem that the production of it becomes troublesome.

Further, a titration plate b from a supply rack c
.. are taken out in parallel with the titration plates b loaded in the supply rack c, so that the sample is much attached to the titration plates b collected in the collection rack f by passing through the cleaning head e. When there is a new one, it is necessary to wait for the order of paralleling when it is taken out and put into the supply rack c again to perform the cleaning by the cleaning head e, and the adhesion of the sample is serious. There is a problem that the quick processing cannot be performed.

Further, from this, the transfer device d is mounted on the body a.
When the titration plate b selected freely from the titration plates b loaded in the supply rack c can be taken out, the titration plates b thus taken out can be transferred one by one. During this time, it is necessary to return the cleaning head to a position where it passes through the cleaning head e, which causes a problem of lowering work efficiency.

Further, when the titration plates b ... Collected in the recovery rack f after passing through the cleaning head e are bathed with warm air in the recovery rack f, when the drying process is performed, the adhered cleaning water is attached. The uneven amount causes unevenness in the progress of the drying, and even in the case of the first product to be collected, the drying becomes insufficient and the post-treatment becomes troublesome.

The present invention has been made in order to solve these problems occurring in the conventional means, and is a titration plate b loaded side by side in front and rear on a supply rack c.
While the transfer device d can be moved back and forth so that the desired titration plate b can be taken out of the above, the supply to the washing head e can be performed efficiently, and the titration plate b ... With a large amount of sample adhered can be washed. The first purpose is to provide a new means that enables quick and accurate operation, and the inside of the recovery rack f of the titration plates b ... A second object of the present invention is to provide a new means for uniformly drying the dried water even if the amount of adhered washing water is different.
