at this time, the fourth electromagnetic valve is opened, then the other electromagnetic valves are all closed, the first motor 1043 rotates reversely, the push rod 14 is pushed to act, the space in the double-head injector 1041 is compressed, the air on the upper portion of the double-head injector 1041 is discharged from the double-head position and enters the dropping needle 105 and the peristaltic pump 103 respectively, the air entering the peristaltic pump 103 is discharged from the fourth electromagnetic valve, after the air in the double-head injector 1041 is discharged, the urine sample can enter the dropping needle 105 and the peristaltic pump 103, the urine sample enters the dropping needle 105 and is detected by the second liquid sensor 8 arranged in the urine sample, and then the urine sample is fed back to the control panel 6.
The control panel 6 performs the next urine sample detection action:
at this time, the four solenoid valves are all in a closed state, and when the first motor 1043 rotates reversely, the second motor 4011 also operates, the second motor 4011 drives the dropping needle 105 to move to the detection device 4 for dropping a sample, the urine sample is pushed out by the push rod 14 pushed by the first motor 1043 and drops on the test paper, when the sample dropping is finished, the second motor 4011 moves reversely to drive the dropping needle 105 to return, the image collector 403 on the second screw nut pair 4012 collects the test paper image after dropping the sample in the returning process, and sent to the control panel 6, the control panel 6 compares the result and sends the information to the user terminal (mobile phone, etc.), at the same time, the push rod 14 pushes to the top to discharge the internal urine sample, then the fourth electromagnetic valve is opened, at the moment, the peristaltic pump 103 rotates forwards to pump the outside air from the fourth electromagnetic valve, and through the first tee 9, peristaltic pump 103, dual head syringe 1041 and the drip needle 105 in sequence to eventually discharge the urine sample.
The control panel 6 performs a flushing action:
during flushing, the first electromagnetic valve 102, the second electromagnetic valve 202 and the third electromagnetic valve 203 are all opened, then the fourth electromagnetic valve is closed, the second motor 4011 returns and stops acting, the first motor 1043 returns and stops acting, external water enters through the second pipeline 201, and partial external water passes through the third tee joint 16 and then passes through the second electromagnetic valve 202 and the first pipeline, so that flushing of a sampling pipe part is realized; part of the external water passes through the third tee joint 16, then sequentially passes through the third electromagnetic valve 203, the fourth tee joint 17, the double-head injector 1041, the peristaltic pump 103, the first tee joint 9 and the first electromagnetic valve 102, and finally is discharged from the first pipeline 101, so that the double-head injector is flushed, and meanwhile, the first motor 1043 acts to drive the push rod to move up and down to empty liquid in the double-head injector 1041; and part of the liquid passes through the third tee joint 16, the third electromagnetic valve 203 and the fourth tee joint 17 in sequence and then is discharged out of the dropping needle 105, so that the part of the dropping needle is flushed.
And finally, carrying out emptying action:
the back is accomplished to the process of flushing, once more the exhaust process, at this moment, four solenoid valves are all closed, first motor 1043 rotates, push rod 14 moves, let the liquid in double-end syringe 1041 discharge, it is partly that gaseous follow syringe needle is got rid of, then control panel 6 control peristaltic pump 103 moves, make it just pass a little time, this time is checked according to the flow and the consumption of pump, then open the fourth solenoid valve, let the air get into, peristaltic pump 103 continues the operation, thereby get rid of unnecessary liquid in the double-end syringe 1041, realize that there is not too much residual liquid in the sampling process next time.
Finally, the initial state of each part is recovered for the next urine sampling, detection and washing.
