In addition, when the sample analyzer 10 is in the manual sample feeding mode, the inductive sensor 13 can also be used for sensing whether the test tube 20 at the sample suction position 111 has a cap, if the inductive sensor 13 does not detect the cap of the test tube 20, the inversion and blending operation is not performed, and then the test tube 20 without the cap is automatically withdrawn, so that the user is reminded to cap the test tube 20, and through the way, the sample detection process can be more reliable.
As shown in fig. 2, in the present embodiment, the inductive sensor 13 is a correlation optical coupler. That is, the inductive sensor 13 may include a transmitting optical coupler 131 and a receiving optical coupler 132, and the transmitting optical coupler 131 and the receiving optical coupler 132 respectively absorb two opposite sides of the sample position 111. The transmission opto-coupler 131 is used for transmitting optical signal, and the receiving opto-coupler 132 is used for receiving optical signal, and the receiving opto-coupler 132 judges whether there is test tube 20 or whether there is a tube cap in test tube 20 according to the condition of received optical signal at the inhale appearance position 111.
In another embodiment, the inductive sensor 13 can also be a reflective optical coupler disposed on one side of the sample sucking site 111 to detect the presence or absence of the cuvette 20/the cap of the cuvette 20 at the sample sucking site 111. The transmitting end and the receiving end of the reflective optical coupler are positioned on the same side.
The relay assembly 12 is used for transporting the test tube 20 inside the sample analyzer 10, for example, the relay assembly 12 can transport the test tube 20 at the grabbing position to the sample sucking position 111, so that the sampling needle 101 of the sample analyzer 10 samples the test tube 20, and the relay assembly 12 can also move the sampled test tube 20 to a preset position.
As shown in fig. 1, the sample analyzer 10 further includes a venous blood mixing component (not shown) and a sample receiving component 16, the sample receiving component 16 is configured to receive the test tube 20 and process the sample in the test tube 20, for example, the sample receiving component 16 may include a micro blood mixing component configured to mix the sample, or the sample receiving component 16 may further include a temperature control component configured to control the temperature of the sample, such as heating or cooling the sample, in other embodiments, the sample receiving component 16 may further include other components configured to process the sample, which is not listed herein.
The venous blood pooling assembly includes a gripper 15, the gripper 15 is configured to grip the test tube 20, for example, the gripper 15 can be configured to at least grip the test tube 20 in the sample receiving assembly 16 onto the transfer assembly 12.
The controller 14 is connected to the locking assembly 11, the transferring assembly 12, the inductive sensor 13, the gripper 15 and the sample receiving assembly 16, and can be used to implement a field cleaning method of the sample analyzer as described below, please refer to fig. 3, where fig. 3 is a schematic flow chart of an embodiment of the field cleaning method of the sample analyzer provided in this application, and specifically, the field cleaning method includes:
s11: and controlling the transfer assembly to move to the sample sucking position.
When the sample analyzer 10 needs to be cleared, the controller 14 first clears the transit assembly 12, that is, the controller 14 controls the transit assembly 12 to move to the sample sucking position 111, so as to determine whether there is a test tube 20 on the transit assembly 12 through the inductive sensor 13 at the sample sucking position 111.
Situations where the sample analyzer 10 needs to be inventoried include: when a fault occurs in the use process of the sample analyzer 10, the field needs to be cleared; alternatively, the sample analyzer 10 may need to be cleaned when the manual sample feeding mode is switched to the automatic sample feeding mode.
Further, the purge sequence of the sample analyzer 10 may be initiated manually, for example, by a purge start button on the sample analyzer 10 when the user desires to perform a purge.
In other embodiments, the purge sequence of the sample analyzer 10 may also be automatically initiated to increase the intelligence of the sample analyzer 10. For example, when the controller 14 receives a command for switching the sample analyzer 10 from the manual sampling mode to the automatic sampling mode, the controller 14 starts a field cleaning process to start executing a step of controlling the transfer assembly 12 to move to the sample sucking position 111, so as to clean the sample analyzer 10 before the automatic sampling mode starts, thereby improving the reliability of the sample analyzer 10.
Further, the controller 14 may also monitor whether the sample analyzer 10 has a fault during the operation process through a sensor disposed thereon, and if the controller 14 confirms that the sample analyzer 10 has a fault, the controller automatically starts a clearing process, that is, starts to execute the step of controlling the relay assembly 12 to move to the sample sucking position 111. A failure herein refers to a situation in which the sample analyzer 10 fails to function properly for some reason, such as the reagent in the sample analyzer 10 is used up.
S12: whether a test tube exists at the sample sucking position is sensed through the sensing sensor.
When the transfer module 12 moves to the sample sucking position 111, the controller 14 senses whether there is a test tube 20 at the sample sucking position 111 through the sensing sensor 13, and thus, whether there is a test tube 20 on the transfer module 12 can be determined.
Optionally, before the step of sensing whether the test tube 20 is present at the sample suction position 111 by the sensing sensor 13, the method for clearing may further include the step of controlling the locking assembly 11 by the controller 14 to perform the operation of centering the test tube 20 at the sample suction position 111. That is, after the relay assembly 12 moves to the sample suction position 111, the locking assembly 11 performs an operation of centering the test tube 20 at the sample suction position 111, and the centering operation of the locking assembly 11 at this time is a process of performing normal detection of the sample by the sample analyzer 10. That is, in this way, the sample analyzer 10 can be controlled easily without changing the original operation flow of the sample analyzer 10.
It is understood that the locking assembly 11 may not perform the above-mentioned centering operation of the sample suction position 111 when the test tube 20 is cleared, and thus, the presence or absence of the test tube 20 at the sample suction position 111 can be sensed by the sensing sensor 13 on the locking assembly 11. By the method, the field cleaning process can be simplified.
S13: when the test tube is confirmed to be arranged at the sample sucking position, the test tube is moved out through the transfer assembly.
When the controller 14 determines that there is a test tube 20 at the sample sucking position 111, it can determine that there is a test tube 20 on the transferring assembly 12, and move the test tube 20 out through the transferring assembly 12, so as to complete the cleaning of the sample analyzer 10.
Specifically, the process of removing the test tube 20 through the transfer assembly 12 may be: when the sample analyzer 10 is in the manual sample feeding mode, the relay assembly 12 moves the test tube 20 from the sample suction position 111 to the outside of the sample analyzer 10, so that the user can take out the test tube 20. When the sample analyzer 10 is in the autosampler mode, the transfer assembly 12 may move the test tube 20 to the grip 15, and then return the test tube 20 to the test tube rack by the grip 15 to complete the clearing of the test tube 20.
In the above embodiment, the sample analyzer 10 can automatically complete the site cleaning work through the inductive sensor 13 at the sample suction position 111, the site cleaning process is simple, the cost is low, the intelligent degree is high, and the reliability of the sample analyzer 10 can be improved.
As shown in fig. 4, fig. 4 is a schematic flowchart of another embodiment of a field cleaning method for a sample analyzer, in this embodiment, the field cleaning method for the sample analyzer 10 includes:
s21: and controlling the transfer assembly to move to the sample sucking position.
Step S21 is the same as step S11, and is not repeated here.
S22: whether a test tube exists at the sample sucking position is sensed through the sensing sensor.
Step S22 is the same as step S12, and is not repeated here.
S23: when the test tube is confirmed to be arranged at the sample sucking position, the test tube is moved out through the transfer assembly.
Step S23 is the same as step S13, and is not repeated here.
S24: when confirming that there is not the test tube in the position of inhaling the appearance, then judge whether there is the test tube on the tongs through inductive pick up.
After the transfer assembly 12 moves to the sample sucking position 111, when the controller 14 determines that there is no test tube 20 at the sample sucking position 111 through the sensing sensor 13, it can be determined that there is a test tube 20 on the transfer assembly 12, and the controller 14 further determines whether there is a test tube 20 on the grip 15 through the sensing sensor 13.
Alternatively, since the grip 15 is in the open state, it can be confirmed that there is no test tube 20 on the grip 15, before the step of determining whether there is a test tube 20 on the grip 15 by the sensing sensor 13, the controller 14 may first obtain the status information of the grip 15, and when the grip 15 is in the open state, it can be confirmed that there is no test tube 20 on the grip 15, and the process goes to step S26 to continue to determine whether there is a test tube 20 in the sample holding assembly 16. When the grip 15 is in the closed state, the sensing sensor 13 is further used to determine whether there is a test tube 20 on the grip 15. By the method, the field cleaning process can be simplified, and the field cleaning time is saved.
In one embodiment, as shown in fig. 5, the step of determining whether the test tube 20 is on the grip 15 by the sensing sensor 13 includes:
s241: the control gripper performs the operation of placing the test tube on the transfer assembly.
In order to confirm whether the test tube 20 is on the gripper 15, it may be assumed that the test tube 20 is on the gripper 15, and then the controller 14 controls the gripper 15 to perform the operation of placing the test tube 20 on the relay assembly 12.
S242: and controlling the transfer assembly to move to the sample sucking position.
After the gripper 15 performs the operation of placing the test tube 20 on the transfer assembly 12, the controller 14 controls the transfer assembly 12 to move to the sample sucking position 111.
S243: whether a test tube exists at the sample sucking position is sensed through the sensing sensor.
After the transfer module 12 moves to the sample sucking position 111, the controller 14 senses whether the test tube 20 is on the transfer module 12 through the sensing sensor 13, so as to determine whether the test tube 20 is on the gripper 15.
When the inductive sensor 13 senses that there is no test tube 20 at the sample sucking position 111, it can be confirmed that there is no test tube 20 at the gripper 15.
S244: if yes, the test tube is confirmed to be arranged on the gripper.
When the sensor 13 senses that there is a test tube 20 at the sample sucking position 111, it can be confirmed that there is a test tube 20 on the gripper 15, and the test tube 20 has been moved to the sample sucking position 111 by the transfer assembly 12.
S245: if not, the test tube is not arranged on the gripper.
If the controller 14 senses that there is no test tube 20 at the specimen aspirating position 111 through the sensing sensor 13, it confirms that there is no test tube 20 on the gripper 15, and then the process goes to step S26 to continue to clean the specimen receiving assembly 16.
