The workflow of automatic clinical chemistry analyzer in the embodiment of the present invention are as follows:
Cup holder driving motor drives reaction cup holder to move to filling position, at this point, the reaction vessel of sample or reagent to be filled
Positioned at the underface for being incubated for filler port on groove body.
Sample or reagent are drawn in the reaction vessel position that probe is rocked to sample or reagent to be drawn, and then return to incubation slot
The underface of filler port on body, lifting motor operation drive and prick under probe into reaction vessel, sample or reagent are filled into anti-
It answers in container.
At this point, probe is detached from liquid level under the drive of lifting motor, after drawing the air of predetermined amount, liquid level is penetrated down again
Hereinafter, executing compressing mixing movement repeatedly, preferably twice.
After mixing, probe is detached under the drive of lifting motor is incubated for groove body, under the drive of rotating electric machine, rotation
To washing station, i.e. service sink position, the cleaning of inside and outside wall is carried out.
Meanwhile cup holder driving motor drives reaction cup holder movement, and passes through from optical measurement channels, optical detection unit is complete
It is measured at the optical data of each reaction vessel specific wavelength, then cup holder driving motor drives reaction cup holder to move to next anti-
It answers container to fill station, continues the movement for filling sample or reagent and mixing, until reaction terminates.
Biochemical Analyzer of the embodiment of the present invention is by taking single reagent reacts as an example, and in each reaction duty cycle, probe has needed
Filling, mixing and the cleaning of Cheng Yici sample and the filling of a reagent, mixing and cleaning.Meanwhile linear incubation slot
Have and moves twice and carry out photooptical data measurement.
Existing Biochemical Analyzer by including at least probe, reaction cup and agitating paddle in the inner, filling and mixing every time
After the completion, it requires to clean reaction cup, probe and agitating paddle, to prevent cross contamination, water consumption is very big, therefore right
Be a kind of puzzlement for the area of part water shortage.Meanwhile semi-automatic biochemical analyzer is taken and manually adds sample and reagent
Mode, there are biggish artificial bias factors, cause the sample size being added every time and amount of reagent to be all not necessarily the same, seriously
The precision for reducing measured value affects the accuracy of test, very big puzzlement is caused to doctor's clinical judgment state of an illness, when serious
It even will affect the life security of patient.
It is rotary-disk type structure that disk is incubated in conventional biochemical analyzer, and reaction cup is to be distributed in be incubated on disk periphery, is incubated
It educates and contains rotate driving in disk, reaction cup is driven to do regular rotation, cooperate probe and the regular rotation of sample reagent disk,
To complete the filling of sample and reagent, and the mixing by the rotation completion of mixing mechanism to liquid in reaction cup.
In the embodiment of the present invention, replaces conventional biochemical analyzer rotating disc type to be incubated for disk by using linear incubation slot, pass
System is incubated among disk in addition to rotating mechanism, remaining region can not be utilized, and the size of thermostat is compared in tradition incubation disk
Fixed incubation slot is bigger.While overall compact utilization space of the invention, overall structure is simplified, is reduced costs.
And the invention proposes probe compressing blending manners, are not necessarily to mixing mechanism, after probe has filled sample every time, immediately
Compressing mixing movement is executed to liquid in current reaction vessel.After the completion of mixing, it is rocked to service sink and is cleaned, saved
The water used to agitating paddle cleaning, saves cost needed for mixing mechanism in traditional analysis instrument each duty cycle.
In contrast, traditional agitating paddle is generally flat paddle agitating paddle, when being stirred to react liquid in container, reaction vessel
Interior liquid condition forms laminar flow, from it is microcosmic liquid in reaction cup is divided into countless lamellas from the point of view of, each layer of liquid is all enclosing
It is rotated around agitating paddle center, in the case where rotating speed of agitator is not high, the liquid on upper layer is difficult to diffuse into lower liquid, such as
Fruit is wanted to reach ideal mixed effect, needs to put forward higher requirements the revolving speed of agitating paddle.
On the contrary, probe compressing blending manner, when liquid is when passing through the probe internal diameter of very small diameter in reaction cup, in probe
Diameter is usually no more than 0.5mm, and liquid falls over each other to be squeezed into probe interior, and when liquid passes through probe tips aperture, liquid occurs
Turbulent flow mixes it tentatively in probe.During liquid is spued from probe interior and enters reaction vessel, due to impact
Power effect, when liquid enters in reaction vessel, is random motion, further mixes to liquid, fill to reach
Divide the purpose mixed.
To sum up, in order to increase instrument reliability, cost is reduced, the size of instrument is reduced, the present invention proposes: including square groove type
Incubation disk, the incubation disk of square groove type need to only be moved forward and backward without rotation.Reaction cup in the circular arc and incubation slot that probe is swung
The intersection or tangent of central line motion profile.Reaction cup where intersection or points of tangency can be used as probe filling position；It is not necessarily to
Mixing mechanism after probe has filled sample every time, executes compressing to liquid in current reaction cup immediately and mixes.It is completed wait mix
Afterwards, it is rocked to service sink to be cleaned, saves water used to agitating paddle cleaning in traditional analysis instrument each duty cycle, section
Cost needed for mixing mechanism is saved, and the ruler that conventional biochemical analyzer rotating disc type is incubated for disk is greatly reduced in linear incubation slot
It is very little, reduce manufacturing cost.
By with the application of the invention, eliminating tradition is incubated for disk disc type mechanism and for mixing to liquid blending in reaction cup
Even mechanism saves conventional biochemical instrument agitating paddle institute water consumption.Can great reduced equipment sizes, reduce the structure of analyzer
Complexity while improving global reliability, reduces costs, also has the advantages that water-saving.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations all should belong to the guarantor of appended claims of the present invention
Protect range.
