For example, when the sample is judged to be the first priority sample, the indicator lamp 41 may be made to display green, and when the sample is judged to be the second priority sample, the indicator lamp 41 may be made to display red.
The following describes an identification method of the sample priority identification device according to the present invention.
In the present embodiment, in the process that the rack with the samples is moved from front to back into the rack slot 14, the trigger protrusion on the rack can depress the detection contact 321 so that the sensor 32 generates the trigger signal.
Because the number of the trigger protrusions arranged on the first test tube rack 21 and the second test tube rack 22 is different (for example, one trigger protrusion and the number of the trigger protrusions are respectively, for example, five trigger protrusions), the signal processing device receives different numbers of trigger signals, and then whether the current test tube rack 14 is the first test tube rack 21 or the second test tube rack 22 can be judged according to the number of the received trigger signals, and then the priority of the samples in the current test tube rack 14 is known.
Further, the signal processing device controls the corresponding indicator lamp 41 to display the corresponding color according to the judgment result. For example, if the first priority sample is, green is displayed; if the sample is the second priority sample, the red color is displayed.
It will be appreciated that the signal processing means may determine the priority of the samples based on the number of trigger signals received within a set time. The set time may be a time required from when the test tube rack just enters the test tube rack 14 to when the test tube rack 14 completely enters the test tube rack 14, and the set time may start to be counted when the signal processing device receives the first trigger signal.
It will be appreciated that a fool-proof mechanism may be provided to ensure that the rack is properly pushed into the rack slot 14. A limit mechanism or sensor may be provided to control the final stop position of the rack during its movement toward the rack slot 14.
By adopting the technical scheme, the sample priority identification device provided by the invention has at least the following advantages:
