Description
Technical field
The present invention relates to medical sanitary apparatus technical field, more particularly to a kind of sampling device of cellanalyzer.
Background technology
Cellanalyzer is one of hospital clinical inspection application instrument widely, swift and violent with computer technology
Development, blood cell analysis also turn to five points of groups from three points of groups, from two-dimensional space and then have turned to three dimensions, and we also note
Five sorting techniques anticipated to modern cellanalyzer employ with current state-of-the-art flow cytometer identical technology, such as dissipate
Penetrate optical detection technique, sheath Flow Technique, laser technology etc..
Existing cellanalyzer sampling device drives belt to move back and forth to realize by motor, its linear movement guide
Mechanism is that linear bearing is supporting with linear steering axle, in automaticity Medical Devices very high, the guiding of linear bearing
Precision has been difficult to meet the requirement being accurately positioned, and due to compact conformation, the axis of guide, length causes two problems of aspect：1,
Axis of guide rigidity deficiency causes the guiding accuracy to reduce.2, though the axis of guide be arrangeding in parallel makes moderate progress to precision, and will to assembling
Ask high, safeguard also inconvenient.And the guiding mechanism of sampling device should possess certain performance, (l) stroke and positional precision will height
(gapless);(2) there are enough rigidity;(3) larger dead load and dynamic loading can be born;(4) damping property is good;(5) rush
Hit protective value good;(6) good airproof performance;(7) it is easy for installation.In sum, it is how thin as blood from suitable guiding mechanism
The problem of born of the same parents' analyzer sampling device urgent need to resolve.
The content of the invention
It is an object of the invention to provide a kind of sampling device of cellanalyzer, the present invention is replaced using linear guides
, as guide transmission gear, load is big, and stability is stronger for existing linear bearing, and rigidity foot, and the positioning precision of system is also obtained
Corresponding raising is arrived；And be easy to process, install and safeguard, interchangeability is high.
In order to reach foregoing invention purpose, the present invention provides a kind of sampling device of cellanalyzer, including test tube sample

And guiding mechanism;The guiding mechanism includes the linear slide rail parallel with the Timing Belt and can be slided on the linear slide rail
Dynamic sliding block；The sliding block is fixedly connected with the Timing Belt, and drives movement by the motor；Also include being fixed on the cunning
The pushing block reciprocatingly moved with the Timing Belt on block；Guiding machine described in promotion lower edge of the cuvette sample holder in the pushing block
The cuvette sample holder that structure will be equipped with test tube is transported to specified location.
Further, the pushing block is fixed with the sliding block by contour screw；Spring is cased with the contour screw.
Further, the pushing block is right-angled trapezium.
Further, including location switch and reset switch；The cuvette sample holder is transported to after specified location institute of setting out
State location switch and send signal instruction, motor drives the pushing block to return to after obtaining the signal instruction that the location switch sends
Original position simultaneously triggers the reset switch and sends signal instruction, and the motor is obtained after the reset switch sends signal instruction
It is stopped.
Further, the location switch and reset switch are made up of photoelectric sensor and microswitch.
Further, including the push-down head, limit lever and the positive stop hook that are fixed on the sliding block；Returned in the pushing block
The push-down head depresses the power arm end of the limit lever, the spacing thick stick being now connected with the positive stop hook after to original position
The resistance arm end of bar rises, and blocks and is transported to the cuvette sample holder of specified location and shrinks back with other testing sample framves forward
It is mobile.
The present invention also provides a kind of sample cell automatic transmission system of cellanalyzer, including described in any of the above one kind
Sampling device, also including dragging sampling device and evenly mixing device；It is described to drag sampling device specified for the sampling device to be transported to
The cuvette sample holder of position is transported to the evenly mixing device, and the evenly mixing device rocks pre-determined number or stops after the time,
It is described to drag sampling device that the cuvette sample holder is sent out from the evenly mixing device.
Compared with the sampling device of existing market, with linear guides as guiding mechanism, line slideway compares straight line to the present invention
Bearing accuracy is high, and load is bigger, and stability is stronger, and rigidity foot, and the positioning precision of system has also obtained corresponding raising；And
And be easy to process, install and safeguard, interchangeability is high.Difficulty of processing and cost are then reduced using the simple pushing block of profile, more
Meet the energy-saving requirement that country advocates.
