Structure is required to carry out pipeline pouring liquid by certain sequential, compressing sample, the flowing of liquid and the collection of accurate quantification and beats
Go out liquid.
The course of work of this instrument is as follows：
First, operator select the fixed lid 1c of different model according to the length of blood taking tube, after choosing, by the 1p that shakes hands
Centrifugation pedestal 1i is extracted out, and blood taking tube is inserted in Block Cartridge 1b, then fixed with fixed lid 1c, after fixing, base will be centrifuged
Seat 1i pushed homes；Then, upper strata movable plate 4b and lower floor movable plate 4c is stretched out by control detection card travel mechanism 4 simultaneously, and
Corresponding detection card is put in holding tank 4d, puts rear upper strata movable plate 4b and lower floor movable plate 4c well while return；Now, just
This instrument can be opened, after this instrument is opened, first control centrifugation motor 1a is rotated and started centrifugally operated, after centrifugally operated is finished, is moved
Model machine structure 3 will move acupuncture treatment mechanism 2 and move to directly over blood taking tube；After motion acupuncture treatment mechanism 2 moves into place, by encoder pair
Blood taking tube is positioned, and is then controlled corresponding acupuncture treatment motor 2c and is driven that corresponding sampling needle 2b is descending to penetrate corresponding blood sampling
Pipe, and quantitative sample is extracted by sampling pump 7c, sample is extracted after finishing, and sampling needle 2b return back to original position, then starts next
The sampling of individual blood taking tube, so circulates, until all sampling needle 2b are extracted finishing；Then, model machine structure 3 is moved again by motion acupuncture treatment machine
Structure 2 moves to the position of detection card, and each sample in sampling needle 2b is dropped on first row detection card；After drop sample is finished, on
Layer movable plate 4b and lower floor movable plate 4c is moved simultaneously inwards, and the first row detection card that drop has sample is moved to detection station；
And then, sweep mechanism 5 just starts to detect first row each the detection card on card is scanned respectively, and result is shown to
On display screen；While drop sample finishes rear, motion acupuncture treatment mechanism 2 return back to initial position, then controls all sampling needle 2b points
Do not insert it is corresponding wash in needle cavity 6b, drawing liquid pump 7b just pumps into cleanout fluid in sampling pump 7c, then by sampling pump 7c by cleanout fluid
Pump in each sampling needle 2b, complete the cleaning of each sampling needle 2b inwalls, meanwhile, wash pin pump 7e also cleanout fluid is pumped into and respectively wash needle cavity
In 6b, the cleaning of each sampling needle 2b outer walls is completed, and after cleaning is finished, each sampling needle 2b return back to initial position；So far, first row
Detection card detection is finished, and second row detection card and the 3rd detection process for listing and indexing survey card are so circulated, and all detection cards have been detected
After finishing (sample in blood taking tube in Block Cartridge 1b is also all detected accordingly and finished), movable plate 4c elder generations of lower floor return, first row
Detection card, second row detection card and the 3rd list and index survey card be sequentially completed automatic off card action under gravity, so as to realize
The automatic recovery of discarded detection card；Finally, upper strata movable plate 4b returns.
