[0030]
Next, a description will be given of a process of confirming a sample contained in a sample rack and a position of the sample in the sample rack by the sample position confirmation system according to the embodiment when storing the sample carried in the inspection institution. .
[0031]
First, a sample container 20 containing a sample is carried into a testing institution. When the sample is carried in, sample information (sample number, reception date, etc.) of the sample is stored in the IC tag 24 housed together with the sample in the housing section 22 of the sample container 20.
[0032]
Next, the loaded sample container 20 is housed in the sample rack 2 by being inserted into an arbitrary storage section 4 of the sample rack 2. Then, a predetermined vibration is applied to the sample rack 2 by, for example, vibrating the sample rack 2 in which the sample containers 20 are stored in the respective storage units 4 left and right. At this time, when the vibration applied to the sample rack 2 is detected by the vibration sensor 18 of the IC tag reader 6, the battery 16 is activated and the supply of power to the data control unit 11 is started. The IC tag reader 6 that has started operating when the power supply is started transmits a radio wave to the IC tag 24 via the antenna 12. That is, a radio wave is transmitted from the IC tag reader 6 arranged at the bottom of each accommodation unit 4 to the IC tag 24 in the sample container 20 accommodated in the accommodation unit 4.
[0033]
The IC tag 24 receives power transmission by radio waves transmitted from the IC tag reader 6. For example, when an electromagnetic induction type RFID tag is used as the IC tag 24, a coil is used as the antenna of the IC tag 24 and the antenna 12 of the IC tag reader 6, and the induced voltage of the two coils is used. To generate power in the IC tag 24. Then, the sample information is transmitted from the IC tag 24 activated by the power generation to the IC tag reader 6 disposed at the bottom of the storage unit 4 in which the sample container 20 having the IC tag 24 is stored.
[0034]
The IC tag reader 6 receives the transmitted sample information via the antenna 12, and stores the received sample information in the data storage unit 14. The above-described processing is performed in all the IC tag readers 6 disposed at the bottom of each of the storage units 4, and the sample information of the sample stored in the sample container 20 stored in each of the storage units 4 is obtained. The data is stored in the data storage unit 14 of the IC tag reader 6.
[0035]
The sample rack 2 may be used when collecting a sample from a medical institution or the like where the sample is collected. That is, the sample container 20 containing the collected sample may be stored in the sample rack 2 when collecting from a medical institution or the like, and the sample information and the position information may be associated at the time of collection.
[0036]
Next, the sample rack 2 containing the sample container 20 is arranged in a range where radio waves from an antenna of the stationary IC tag R / W 34 can reach. The stationary IC tag R / W 34 reads sample information and position information stored in each IC tag reader 6 disposed at the bottom of each storage unit 4 of the sample rack 2, and reads the read sample information and position information. The corresponding information is transmitted to the PC 32 as sample position confirmation information.
[0037]
In the PC 32, the sample position confirmation information read by the stationary IC tag R / W 34 is received via the communication control unit 42, and the received sample position confirmation information is stored in the data storage unit 44. Therefore, the sample contained in the sample rack 2 can be grasped, and the position of the sample in the sample rack 2 can be grasped.
[0038]
Next, when a sample stored in the sample rack is extracted for an inspection, a retest, or the like, a process of confirming the extracted sample is performed as shown in the flowchart of FIG. .
[0039]
First, a sample withdrawal instruction transmitted from the core system that performs test management or the like is received via the communication control unit 42 (step S10). That is, the sample information of the sample instructed to be extracted from the sample rack 2 is received. The received extraction instruction is stored in the data storage unit 44.
[0040]
Next, the received extraction instruction is displayed on the display unit 46 (step S11). That is, based on the sample position confirmation information stored in the data storage unit 44, the sample information of the sample for which extraction has been instructed and the storage unit 4 in the sample rack 2 in which the sample is stored in correspondence with the sample information. Is displayed on the display unit 46.
[0041]
Here, the operator first extracts a predetermined sample container 20 from the sample rack 2 based on the extraction instruction displayed on the display unit 46. Next, a predetermined vibration is applied to the sample rack 2 by, for example, vibrating the sample rack 2 from which the predetermined sample container 20 has been extracted. In the sample rack 2, the applied vibration is detected by a vibration sensor 18 provided in each IC tag reader 6 disposed at the bottom of each storage unit 4, and the battery 16 is activated to activate each IC tag reader 6.
[0042]
The IC tag reader 6 reads the sample information stored in the IC tag 24 in the sample container 20 stored in the storage unit 4 in which the IC tag reader 6 is arranged, and stores the read sample information in the data storage unit 14. To memorize.
[0043]
Next, the sample rack 2 is arranged in a range where radio waves transmitted from the stationary IC tag R / W 34 reach. The stationary IC tag R / W 34 reads the sample information and the position information stored in the data storage unit 14 of each IC tag reader 6, associates the read sample information with the position information, and uses the read information as the sample position confirmation information. Transmit to PC32.
[0044]
In the stationary IC tag R / W 34, only the position information is read from the IC tag reader 6 arranged at the bottom of the container 4 from which the sample container 20 has been extracted. Here, when only the position information is read, there is no sample information associated with the position information, and thus the read position information cannot be associated with the sample information and is not transmitted to the PC 32. Therefore, only the sample position confirmation information of the sample stored in the storage unit 4 of the sample rack 2 is transmitted to the PC 32.
[0045]
The PC 32 receives the specimen position confirmation information transmitted from the stationary IC tag R / W 34 via the communication control unit 42 (Step S12). That is, based on the withdrawal instruction, sample position confirmation information indicating the sample contained in the sample rack 2 after the sample has been extracted and the position of the sample in the sample rack 2 is received.
[0046]
Next, it is confirmed that the sample instructed to be extracted has been extracted from the sample rack 2 (step S13). That is, first, by comparing the sample position confirmation information stored in the data storage unit 44 before the extraction is performed with the sample position confirmation information after the extraction is performed, the extracted sample and the extracted The position in the sample rack 2 in which the sample has been stored is confirmed. Next, whether or not the specified sample has been extracted is checked by comparing the extraction instruction stored in the data storage unit 44 with the sample information of the sample whose extraction has been confirmed.
[0047]
If there is an error in extracting the sample (step S14), a warning is displayed on the display unit 46 indicating that there is an error in extracting the sample (step S15). That is, when the sample information of the sample whose extraction has been confirmed and the sample information for which the extraction instruction is issued do not match, it is confirmed that there is an error in the extraction of the sample. Therefore, in this case, a warning indicating that there is an error in sample extraction is displayed on the display unit 46 together with the sample position confirmation information of the sample for which the collation did not match.
[0048]
When a warning indicating that there is an error in sample extraction is displayed on the display unit 46 (step S15), after confirming the extraction instruction, the sample is extracted again, and after a predetermined vibration is applied to the sample rack 2, Then, the sample rack 2 is arranged in a range where radio waves from the stationary IC tag R / W 34 can reach, and the sample removed by performing the processes of steps S12 and S13 is confirmed.
[0049]
On the other hand, if the sample information of the sample whose extraction has been confirmed matches the sample information for which the extraction instruction has been issued (step S14), it is confirmed that the sample has been correctly extracted. Therefore, the process ends.
