Description

[Detailed Description of the Invention] [Industrial Application Field] This invention dispenses a test liquid, such as serum, into a plurality of containers corresponding to the number of test fields and according to the number of test items for each container. This invention relates to a dispensing device for dispensing small amounts.

[Conventional technology]

In the past, various dispensing devices for dispensing the same type of liquid to be tested have been developed, an example of which is the dispensing device (
Jitsugan Sho 62-67021. 67023). This is done by setting the parent sample and multiple sub-sample containers to be dispensed on a rack in advance, and by reciprocating the dispensing nozzle between the parent sample rack and the sub-sample containers to be dispensed. [Problems to be Solved by the Invention] The conventional apparatus described above performs so-called patch processing, and therefore performs batch processing for each parent sample. When setting whether to dispense or not and the amount to be dispensed, only uniform instructions can be given to one rack, and when dispensing is not performed, the patch position of the corresponding sub-sample container to be dispensed As a result, after dispensing, it is necessary to rearrange the containers again, which requires extra work. Further, the sample information on the preliminary sample container after dispensing can only be confirmed using a patch on the rack, and there is a possibility that a recognition error may occur during visual confirmation after sorting.

Furthermore, in terms of operation, in order to ensure efficient operation of the aforementioned dispensing equipment, the dispensing process is performed as soon as the number of samples stored in the rack is collected, so that the handling of emergency test samples and the overall dispensing work are performed. In terms of shortening the time required for moxibustion, the development of a dispensing device capable of real-time processing, so-called random access or moxibustion, has been desired.

Therefore, the present invention makes it possible to easily dispense the number and amount according to the test field and test items set for each parent sample, and also to recognize the preliminary sample container after dispensing. In addition, it is an object of the present invention to provide a dispensing device that enables so-called random access or real-time processing.

[Means for solving problems]

In order to solve the above problems, the present invention has taken the following measures. That is, a parent sample transfer means that transports a parent sample container holder that individually holds parent sample containers containing parent samples to a dispensing position, and a parent sample recognition device that reads individual sample recognition information given to the parent sample containers. an information reading means, a sample information storage means for accumulating individual test information of the parent sample, and a first step that recognizes the test field and test item of the parent sample based on the individual sample recognition information and the individual test information; a control means for sending out second and third equipment control signals; and a pre-sample container supply means for supplying a number of pre-sample containers according to the test field of the parent sample based on the first equipment control signal. ,
Pre-sample individual information adding means for adding the same individual sample recognition information as the parent sample onto the child sample container based on the second device control signal; and a pre-sample container holder for individually holding the preliminary sample container. a pre-sample transport means for transporting the body to the dispensing position; and a pre-sample transport means for transporting the body to the dispensing position, and each pre-sample container to which individual specimen recognition information identical to that of the parent specimen is given based on the third device control signal, according to the test item. The sample should be equipped with a dispensing means for dispensing the parent specimen in portions.

[Effect]

In the present invention that takes such measures, the individual specimen recognition information of the parent specimen identified by the parent specimen recognition information reading means is sent to the control means, and further, this control means reads the individual specimen recognition information of the parent specimen. Individual test information for the corresponding parent sample is received from the sample information storage means. Based on the individual test information, the control means recognizes the test field and test item of the parent specimen, and based on the test field information, the control means sends a first equipment control signal to the pre-sample container supply means. ,
The pre-sample container supply means supplies a number of pre-sample containers corresponding to the number of test fields, and a second device control signal is sent to the pre-sample individual information providing means to recognize an individual sample that is the same as the parent sample. Information is given to the preliminary sample container. Further, based on the test item information, the control means sends a third device control signal to the dispensing means to dispense an amount of parent sample into each preliminary sample according to the number of test items to be tested on each preliminary sample. Dispense into containers.
