Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This device is operated using blood collection tubes with identification marks such as barcode labels affixed to them. The present invention relates to an automatic analyzer.

0002

[Prior art and its issues]

As is well known, the number of automated analyzers used in recent years for biochemical and immunological analysis has increased. In order to prevent mistakes such as sample mix-up, patient information is not disclosed in the field. It is operated by attaching barcoded labels to blood collection tubes, etc.

0003 Therefore, the automatic analyzer side also reads the information on the barcode label and This requires corresponding sampling operations, resulting in the recent automatic Various analysis devices have been proposed that have a barcode reader installed in the transfer path of the blood collection tube. has been done.

0004 However, in the automatic analyzer equipped with the above conventional barcode reader, If the patient information cannot be read even though the barcode label is not soiled. The current situation is that many cases occur. This is because the blood collection tube is cylindrical and , the blood collection tubes are held in a rack with slits for barcode reading. Generally, the barcode part of the barcode label is transported in This is because they are often not held so as to face the slit of the rack.

[0005] In addition, with this type of automatic analyzer, the information read from the barcode label information is sent in real time from the host computer through the serial interface. After checking the test item reception corresponding to the patient information sent by Generally, a series of analytical processing tasks are performed, including However, if the patient information cannot be read, the blood collection tube for which the patient information could not be read is , because they are transferred to a blood collection tube stocker etc. without being sampled. This not only results in the analysis data sheet being incomplete, but also significantly reduces the analysis processing time. As a result, this improvement was strongly requested.

[0006] This idea was devised in view of the current situation, and its purpose is If the information on the barcode label cannot be read, it will automatically be read. The analysis process can be improved by configuring the vessel to stop transport and reread. We aim to provide an automatic analysis device that can perform analysis reliably and quickly. It is something.

[0007]

[Means to solve the problem]

In order to achieve the above purpose, this invention uses multiple blood collection tubes at a predetermined time. A transport means for transferring the specimen by a tube, and a sample for aspirating and dispensing the required amount of specimen from the blood collection tube. A pulling device, a reading device that reads the information on the identification marks affixed to each blood collection tube, and , the input signal from the above reading device cannot be read by the automatic analyzer equipped with a transfer stop means for detecting this and stopping the transfer of the blood collection tube in a certain case; A rereading means is provided to reread the information on the identification mark of the blood collection tube that cannot be read. It is characterized by:

[0008] An alarm circuit is connected to the transfer stop means, and input from the reading device is connected to the transfer stop means. If the signal is unreadable, the alarm circuit will generate an alarm or display an alarm on the display. In addition, the re-reading means is configured to display information on unreadable blood collection tubes. The information is automatically reversed to the reading position, and the unreadable information is read at the reading position. The system is characterized by a configuration in which re-reading is performed by rotating the flexible blood collection tube. It is something to do.

[0009]

[Effect]

Therefore, according to this invention, patient information on the identification mark affixed to the blood collection tube can be read. If not, the sampling process will not continue, but the sample The reading operation can be interrupted and the information reading operation of the blood collection tube can be performed again.

【Example】

This invention will be described in detail below based on an embodiment shown in the accompanying drawings.

[0011] The automatic analyzer shown in FIG. If the patient information on the label cannot be read, after temporarily stopping the transfer of the blood collection tube 1, It is configured to send the information backwards to the reading position and reread it. , reference numeral 2 designates a transfer path for intermittently transferring the blood collection tube 1 in the direction indicated by the arrow in the figure. 3 is a drive device for the transfer path 2, and 4 is an optical sensor for detecting the starting position of the blood collection tube 1. 5 is a barcode reader that reads the barcode attached to the blood collection tube 1; 6 is a barcode reader that reads the barcode attached to the blood collection tube 1; Optics for detecting the reading position of the blood collection tube 1 identified by the barcode reader 5 Each sensor is shown.

0012 In addition, the reference numeral 10 in the figure is a microprocessor device built in this automatic analyzer. This microprocessor device 10 receives input from the barcode reader 5. A reading unit 11 reads the 0 and 1 signals, and a data memory corresponding to the reading result. a data reading section 13 for reading out necessary information from 12; Alarm when the reading unit 11 cannot identify the input signal from the barcode reader 5 The alarm activation unit 14 that lights up the lamp 20 and the reading unit 11 are the barcode reader 5. If the input signal from the input signal cannot be identified, the transfer drive of the drive device 3 is stopped; and a reverse transport command unit 1 that issues a command signal to transport the blood collection tube 1 back to the information reading position. 5. Note that the command from the reverse feed instruction section 15 to the drive device 3 is The command can read the stop command signal for transferring blood collection tube 1 and the barcode again. It is sufficient that the signal content is sent backwards by the minimum necessary pitch to achieve the required function.

[0013] The transfer path 2 includes, for example, sprockets 21 and 22, a tension pulley 23, and a tension pulley 23. It is driven using a timing belt 24. In addition, reference numerals 25 to 28 in the figure are startup stages. There are various operation switches such as switches, stop switches, and continue switches, and 30 is a multiple switch. 31 is a plurality of reaction tables that hold several reaction vessels and rotate them at a predetermined pitch. This is a reagent table that holds and rotates reagent containers at a predetermined pitch. Furthermore, the original person The dynamic analyzer is generally equipped with a pipette device, washing device, and A mechanism similar to that of an optical measurement device is installed, but for convenience of explanation, illustration is omitted. Ta.

[0014] Next, the operation of the automatic analyzer configured as described above will be explained.

[0015] First, before starting up the device, insert the blood collection tube 1 with the barcode label pasted onto the transfer path. Set it on chain rack 2. In this case, the slit in the chain rack (as shown) Collect blood from the barcode label with the barcodes lined up in the direction in which the Attach it to tube 1 and hold it on the rack with the barcode facing the slit. let

[0016] Next, set the chain tray on the sample feeder and place it on the first chain rack. Manually slide it to the optical sensor 4 position. At this time, the optical sensor 4 The blood collection tube 1 is detected and a predetermined lamp is displayed.

[0017] When the start switch 25 is turned on from this state, the chain rack on the transfer path 2 is turned on. It is automatically fed intermittently to the position of the optical sensor 6, stops at that position, and then moves to a predetermined lap. is displayed.

[0018] Then, at the same time that the presence of the blood collection tube 1 is confirmed by the optical sensor 6, the bar A barcode reading operation is performed by the code reader 5.

[0019] This barcode reader 5 has successfully read the barcode. If the sample tube 1 is automatically sent to the sampling position, the sampling tube 1 is The sample is aspirated by a pet (not shown), and then a conventional automated aspiration process is performed. Analytical work is performed using the same process as that used for analytical equipment. In this case, barcode reader 5 The read barcode information is sent to the reading section 11 in the microprocessor device 10. Based on the information, the data reading section 13 writes the data into the data memory 12 or the host controller. The necessary data are read out from the data recording section of a computer (not shown) and the reaction analysis is performed. (not shown).

[0020] On the other hand, the barcode reading operation by the barcode reader 5 is not performed normally. If not, an NG signal from the reading section 11 in the microprocessor device 10 Based on this, the alarm activation unit 14 lights up or blinks the alarm lamp 20, or issues an alarm. At the same time, the reverse feed instruction unit 15 sends a command to the drive device 3, and this command signal Based on this, the drive device 3 causes the transfer path 2 to move backward at a predetermined pitch, so that the blood collection tube 1 reaches the barcode. Automatically reset to the position of the barcode reader 5 and reread by the barcode reader 5 Collection work will be carried out. In this case, a blood collection tube 1 is placed above the barcode reader 5. By making elastic contact with the upper end and rotating the blood collection tube 1, the barcode is inserted into the chain rack slider. It is desirable to provide a blood sampling tube rotating device that resets the tube so that it faces the cut. This collection The rotation operation of the blood vessel is performed manually or by a rotation device.

[0021] Although not shown, the rotating device includes a motor and a rotating shaft connected to the rotating shaft of the motor. A rotating rod, a rotor elastically supported at the lower end of the rotating rod via a coil spring, and the rotating rod. and a lifting device that lifts and lowers the rotation mechanism, and is configured by the barcode reader 5. Activates when barcode information cannot be read even after re-reading. It is desirable that it be controlled so that

[0022] In this way, the barcode reader 5 rereads the barcode. After reading the code information, the transfer path 2 starts operating in the forward direction, and the blood collection tube After 1 is transported to the sampling position, the prescribed processing is performed according to the above procedure. be called.

[0023] On the other hand, even if the barcode information is reread by the barcode reader 5, If the information cannot be read, the operator should turn on the stop switch 26. Stop the transfer path 2, and select the blood sample tube 1 from the keyboard (not shown) on the operation panel. Barcode information can be directly entered manually. The operator also selects the Continue switch. By pressing the switch 27, you can ignore the unreadable blood collection tube 1 and start other blood collection tubes. It can be manipulated to treat blood vessels. This continuation switch 27 is selected. In this case, the unreadable blood collection tube 1 will be ignored and the data sheet will indicate that. recorded. Furthermore, if the operator does nothing in particular, the reverse feed instruction section 1 After issuing the reverse feeding command a predetermined number of times, 5 stops re-reading the blood collection tube 1 and starts the next blood collection. Perform reading work for tube 1. Of course, the error comment is also included in the data sheet in this case. It will be recorded on the website etc.

[0024] Also, the data reading unit 13 reads the barcode information read by the reading unit 11. When an item request is accessed to the data memory 12, the corresponding item in the data memory 12 is Even if data related to the barcode information is not stored, this automatic analyzer can Perform the same operation as above. That is, the alarm lamp 20 (or another lamp) is lit. Alternatively, an alarm is issued and the transport path 2 is reversed by a predetermined pitch to reread the barcode. Perform loading. If the alarm lamp 20 lights up or the alarm continues to sound, turn off the The operations to be performed by the operator are also the same as described above. However, if the data memory 12 contains If the barcode information data does not exist, the operator presses the keyboard. It is possible to enter the necessary information from the code.

[0025] In the above embodiment, barcode information is read using an alarm lamp or an alarm. The explanation was given using an example where the configuration is configured to warn of disabled status, but it is not possible to display it on a CRT etc. It can also be configured so that the barcode information becomes unreadable. For example, SKIP SAMPLE or NO. 10 ID BEEN R Display error messages such as EAD, NO10, ID FOUND, etc. on the CRT. can also be printed out.

[0026]

[Effect of the idea]

As explained above, according to the automatic analyzer according to this invention, the If the patient information on the identified identification tag cannot be read, the sampling process will continue. Instead of continuing, the sampling operation is interrupted and the information reading operation of the blood collection tube is performed. Since the structure is configured so that the process is re-performed, the analysis process can be performed reliably and quickly without any waste. This has the effect that it can be carried out easily.
