Please refer to FIG. 1 , which is a preferred embodiment of the present invention. The content of the foregoing embodiment is not described in detail herein. The difference between this embodiment and the foregoing embodiment is as follows:

The first detection analysis component 22 and the second detection analysis component 23 are all optocoupler components for facilitating material acquisition and installation, and also for better ensuring the accuracy of detection; in addition, for convenience of description, the first detection analysis component 22 The first optocoupler assembly is defined as a second optocoupler assembly; wherein the optocoupler assembly is mainly composed of an optocoupler and a fixed optocoupler. Optocoupler is an optical coupler (optical Coupler, abbreviated as OC) is also known as opto-isolator or optocoupler. It is a device that transmits electrical signals by means of light. Generally, an illuminator (infrared light emitting diode (LED)) and a light receiver (photosensitive semiconductor tube) are packaged in the same package. When the input terminal is powered, the illuminator emits light, and after receiving the light, the photoreceptor generates a photocurrent, which flows out from the output end, thereby realizing the "electric-optical-electrical" conversion. The optocoupler that couples the input signal to the output end with light as a medium, because of its small size, long life, no contact, strong anti-interference ability, insulation between output and input, one-way transmission signal, etc. Widely used on circuits.

In addition, when mounting the first optocoupler assembly and the second optocoupler assembly, in order to ensure the accuracy of the detection, the first optocoupler assembly must face the tube cap portion of the sample tube 2, and the second optocoupler assembly is opposed. The bottom of the tube of sample tube 2.

The detection analysis transfer unit 24 preferably has a detection analysis conveyor belt 241 and a detection analysis drive source connected to the detection analysis conveyor belt 241 for driving the detection analysis conveyor belt 241 to move, wherein the detection analysis conveyor belt 241 is detecting the analysis drive source. After the driving is moved, it moves along the Z direction shown in FIG. 1 to smoothly and smoothly pass the sample tube 2 through the first optocoupler assembly and the second optocoupler assembly on the inspection mount 21. In order to facilitate material acquisition and control cost, the detection and analysis driving source is preferably a stepping motor.

Since the output signal of the optocoupler is mainly high and low level signals, in blood cell analysis, the possible values may be predefined. The specific definition is that when the optocoupler is occluded, the output value is "1", unoccluded, and the output value is "0". Then, the output signal combination of the two optocouplers has: "00", "01", "10", "11", respectively, the corresponding meanings are: the test tube rack 3 has no test tube at the current position, and the current position of the test tube rack 3 is pre- Dilution test tube, test tube rack 3 The current position is a test tube with no sample of whole blood, and the test tube holder 3 is a test tube with a sample of whole blood.

The operation of the sample tube type identification device when the detection mode is set to the venous whole blood detection operation mode and the pre-dilution detection operation mode will be separately described below. When the venous whole blood detection operation mode is set, the test tube rack 3 is sent to the detection analysis position of the detection analysis device 20 by the sample introduction device 10. When the test tube rack 3 is sent to the detection and analysis position, the test and analysis transport assembly 24 will drive the test tube rack 3 to move in the Z direction. At this time, the test tube rack 3 will first pass through the first optocoupler assembly, and the first on the test tube rack 3 The test tube is first detected by the first optocoupler assembly, and since the first test tube has a test tube cap, the output value of the first optocoupler assembly is "1"; then, the test tube rack 3 passes the second light The coupling assembly, likewise, the first tube on the test tube rack 3 is first detected by the second optocoupler assembly, and also because the first test tube has a sample, then the output value of the second optocoupler assembly is "1" Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is "11", and this also indicates that the first test tube matches the detection working mode, and the control device The first tube will be allowed to continue to perform subsequent operations of the test mode of operation.

For the second test tube, since it is a test tube with no blood sample, the output values detected by the first optocoupler assembly and the second optocoupler assembly are “1” and “0”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is “10”, and this also indicates that the second test tube does not match the detection operation mode, and the control device This will cause the second tube to skip the subsequent operation of the test mode of operation.

For the third test tube, since it is a sample pre-dilution test tube, when the first photocoupler assembly and the second optocoupler assembly pass through, the detected output values are “0” and “1”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is “01”, and this also indicates that the third test tube does not match the detection operation mode, and the control device This will cause the third tube to skip the subsequent operation of the test mode of operation.

For the fourth test tube, since it is a sample-free pre-dilution test tube, when the first photocoupler assembly and the second optocoupler assembly pass through, the detected output values are “0” and “0”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is “00”, which also indicates that the fourth test tube does not match the detection mode of operation, and the control device This will cause the fourth tube to skip the subsequent operation of the test mode of operation.

After all the tubes pass the detection and analysis device, the second sample tube is shown as a whole blood sample-free test tube, the third sample tube is a sample pre-dilution tube, and the fourth sample tube is a sample-free pre-dilution. In the test tube, the above test tube does not match the venous whole blood test mode, so skip it and do not perform the test.

When the detection operation mode is set to the pre-dilution detection operation mode, the test tube rack 3 is sent to the detection analysis position of the detection analysis device 20 by the sample introduction device 10. When the test tube rack 3 is sent to the detection and analysis position, the test and analysis transport assembly 24 will drive the test tube rack 3 to move in the Z direction. At this time, the test tube rack 3 will first pass through the first optocoupler assembly, and the first on the test tube rack 3 The test tube is first detected by the first optocoupler assembly, and since the first test tube has a test tube cap, the output value of the first optocoupler assembly is "1"; then, the test tube rack 3 passes the second light The coupling assembly, likewise, the first tube on the test tube rack 3 is first detected by the second optocoupler assembly, and also because the first test tube has a sample, then the output value of the second optocoupler assembly is "1" Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is "11", and this also indicates that the first test tube does not match the detection mode of operation, and the control The device will cause the first tube to skip the subsequent operation of the test mode of operation.

For the second test tube, since it is a test tube with no blood sample, the output values detected by the first optocoupler assembly and the second optocoupler assembly are “1” and “0”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is “10”, and this also indicates that the second test tube does not match the detection operation mode, and the control device This will cause the second tube to skip the subsequent operation of the test mode of operation.

For the third test tube, since it is a sample pre-dilution test tube, when the first photocoupler assembly and the second optocoupler assembly pass through, the detected output values are “0” and “1”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler assembly and the second optocoupler assembly is "01", and this indicates that the third test tube matches the detection mode of operation, and the control device allows The first tube can continue to perform subsequent operations of the test mode of operation.

For the fourth test tube, since it is a sample-free pre-dilution test tube, when the first photocoupler assembly and the second optocoupler assembly pass through, the detected output values are “0” and “0”, respectively. Correspondingly, the signal recognition module on the control board recognizes that the signal transmitted by the first optocoupler component and the second optocoupler component is “00”, which also indicates that the fourth test tube does not match the detection mode of operation, and the control device This will cause the fourth tube to skip the subsequent operation of the test mode of operation.

After all the tubes pass the detection and analysis device, the first sample tube is shown as a whole blood sample tube, the second sample tube is a whole blood sample-free tube, and the fourth sample tube is a sample-free pre-dilution. In the test tube, the above test tube does not match the pre-dilution test mode, so skip it and do not perform the test.

The control device will cause the test tube to skip the subsequent operation of the detection work mode, and give the reason for skipping after the end of the whole test work mode, which greatly saves the user's time and avoids the risk caused by the misoperation. At the same time, it can accurately give the problem of the test tube.
