[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a blood test performed by a blood test apparatus at a blood test center or a hospital, samples blood such as red blood cells, serum, plasma, etc., and reagents, etc. in small units for each test item. The present invention relates to an improvement of a titration plate cleaning device for washing the titration plate for reuse after the end of the inspection.

[0002]

2. Description of the Related Art A titration plate used in a blood test apparatus is usually formed by molding a transparent synthetic resin material into a rectangular flat plate, and a large number of test holes are arranged vertically and horizontally on the surface side of the plate. It is configured by forming.

In the blood test, the titration plate is set in a dispenser of a blood test apparatus, and a sample is placed in each test hole by a dispense nozzle mounted on a dispense head provided in the dispenser. It is performed by pouring, mixing and reacting, then transferring this titration plate to a discriminating / analyzing device, and inspecting / judging.

The titration plate used for this inspection is washed to reuse the specimen or the like dispensed in each test hole at the time of the inspection. Otherwise, it will make the discrimination wrong or cause contamination, resulting in defective judgment.
When used for virus inspection, complete cleaning is required because residual contamination will affect the inspector who handles it.

The means for cleaning the titration plate after use is as follows:
Usually, as shown in FIG. 1, on the upper surface side of a box-shaped machine body a, there is provided a pedestal for supporting the titration plates b by arranging them in a horizontal direction in a laterally laid-down posture. A moving member c is provided so as to move in the left-right direction along the row of lines, and a cleaning nozzle d for injecting cleaning water, cleaning liquid, or the like is supported on the lateral titration plate b. .

[0006] Further, when this means finishes washing the loaded titration plates b, the operation is stopped, the titration plates b are completely taken out, and the titration plates b to be washed next are set. I have to
Since the titration plates b ... Are intermittently supplied and workability is poor, the titration plates b ... are laid sideways on one side of the upper surface of the machine body a as shown in FIG. A supply rack e for accommodating in a parallel state is provided in the container, and a rear feeding mechanism for sequentially feeding the titration plates b, ... A lateral transfer device f for carrying out the titration plate b located there from the rear end part in the rack e and transferring it to the other side of the upper surface of the machine body a is provided, and a washing nozzle d is provided in the middle of the lateral transfer device f. On the other side of the upper surface of the machine body a, there is provided a recovery rack g for recovering the titration plate b transported by the lateral transfer device f and subjected to the cleaning action by the cleaning nozzle d, and the titration plates b ... Sequentially before It has been developed means for configuring by incorporating a forward feed mechanism for feeding the.

Further, in the means shown in FIGS. 1 and 2, it is difficult to completely clean the specimen adhering to the test hole of the titration plate b. Therefore, the titration plate b to be washed after use is preliminarily treated with a chemical solution. Means for combining chemical baths for soaking have also been developed.

[0008]

In the conventional apparatus for washing a titration plate after use in a blood test apparatus, in the means shown in FIG. 1, the titration plates b ... Nozzle d that moves past the side of
Since the cleaning is performed by spraying cleaning water by means of the above, it takes a lot of time to take out the cleaned titration plates b ... There is an unexpected problem.

Further, in the means shown in FIG. 2, the titration plates b to be supplied to the supply rack e are successively carried out by the lateral transfer device having the transfer direction as one direction, and then to the recovery rack g located on the opposite side. Sending in and washing nozzle d during this transfer
Of a large number of titration plates b
It becomes possible to continuously wash the ..., but its washing action is that the titration plate b has a washing nozzle d at a constant speed.
There is a problem that the washing of the titration plate b, which is heavily contaminated, becomes insufficient because it depends on the transfer speed of the lateral transfer device f that transfers the titration plate b so as to pass through the working range of.

Further, when the supply rack e in the means shown in FIG. 2 is used as a chemical solution tank so as to be immersed in the chemical solution prior to cleaning, a lateral transfer device for sequentially laterally transferring the titration plates b ... In f, a lifting mechanism for taking out the titration plate b from the chemical solution tank and a mechanism for hanging the transferred titration plate b in the recovery rack g are required, which causes a problem that the mechanism becomes extremely complicated. Come on.

Further, when the chemical liquid filled in the chemical liquid tank is deteriorated, there is a problem that it takes time to collect and discard the chemical liquid in order to replace it with a new chemical liquid.

Further, in order to improve the efficiency of the cleaning action by immersion in the chemical liquid in the chemical liquid tank, a titration plate b accommodated in parallel in the chemical liquid tank when the ultrasonic vibrator was assembled.
It is difficult for all of them to be exposed to the generated vibration wave, and there is a problem that the effect of using the ultrasonic vibrator cannot be sufficiently obtained.

The present invention has been made in order to solve these problems occurring in the conventional means, in which a titration plate to be washed is preliminarily dipped in a supply rack as a chemical solution tank, and then the chemical solution tank is immersed therein. The purpose of the present invention is to provide a new means capable of simplifying the entire configuration including the lateral transfer device while sequentially taking out the titration plate with the lateral transfer device and passing it through the washing nozzle to be housed in the recovery rack. To do.

[0014]

The present invention proposes a washing device for a titration plate after use in a blood test apparatus formed.

[0015]

According to the means of the present invention, the titration plate immersed in the chemical solution in the chemical solution tank is hung by the horizontal transfer device by the descending operation of the chemical solution tank, and is conveyed toward the recovery rack by the transfer operation of the horizontal transfer device. Then, cleaning is performed by the cleaning nozzle during this transportation, and then a predetermined position in the recovery rack is selected by the slides on the front and rear of the frame of the lateral transfer device, and a notch window hole provided on the side surface of the recovery rack. The horizontal transfer device does not require a mechanism for hoisting and lowering the titration plate because it is loaded into the collection rack at a predetermined position through the passage hole. A rear feed mechanism and a front feed mechanism for moving the front and rear direction are not required, and the entire mechanism can be simplified.

Further, by using the raising / lowering operation of the chemical solution tank for taking out the titration plate from the chemical solution tank, it is possible to open a large-diameter valve provided on the bottom surface of the chemical solution tank.
It is possible to promptly dispose of and collect the chemical liquid from the chemical liquid tank.

Further, a large number of titration plates are housed side by side in a front and rear direction in the chemical liquid tank, and the ultrasonic transducers of the chemical liquid tank are arranged so that the wave direction of the vibration wave generated thereby becomes the front-back direction. The vibration wave generated by the ultrasonic vibrator is arranged in parallel in the chemical tank by installing it on the machine wall on the front side or the rear side and sequentially taking out the titration plate from the side facing the vibration wave and transferring it laterally. It effectively works on all of the large number of titration plates contained.
