The utility model is further described below with reference to the actual course of work.
The utility model needs to cooperate dedicated centrifugally operated equipment, stores needed for each operation of CD in the equipment
The rotation time and velocity of rotation wanted.The centrifugally operated equipment not within the scope of protection of this application, therefore repeats no more.
The CD mentioned in the utility model is made of high molecule plastic, and reagent 11 and quantitative pond 12 etc. are using molding
Production, conduit A21, U-tube 22 and conduit B23 etc. are integrated on a CD using accurate die pressing or etching production.
In use, reagent is injected reagent 11 or directly uses the CD of built-in reagent packet.
Start centrifugally operated equipment, CD starts turning, and reagent is flow to along conduit A21, U-tube 22 and conduit B23
In quantitative pond 12, with the inflow of reagent, the air in quantitative pond 12 starts to shift into run-off.When quantitative pond 12 is filled
Afterwards, extra reagent flows in run-off.The air in run-off is compressed simultaneously, when the air pressure in run-off increases to centainly
After degree, reagent is not entered back into.
What the input terminal of conduit B23, conduit C4 and reagent 11 were connected together, the air pressure in conduit C4 is greater than conduit
The air pressure of the input end of fluid pressure and reagent 11 in B23, therefore during CD rotates forward, reagent is to quantitative pond
12 flow rather than flow in conduit C4.
Description below is made to the pressure at this:
The pressure of conduit B23 and quantitative 12 junction of pond is provided by the reagent in conduit A21 and U-tube 22, conduit C4 with
The pressure of quantitative 12 junction of pond is provided by the air in conduit C4.Under the influence of centrifugal force, in conduit A21 and U-tube 22
Liquid there is the movement tendency far from cd centre, the air in conduit C4 equally also there is the movement far from cd centre to become
Gesture.With reference to pressure formula P=ρ gh of reference fluids, as the pressure P that the air in conduit C4 provides1=ρ1g1h1Greater than conduit A21
The pressure P provided with the reagent in U-tube 222=ρ2g2h2When, it will be able to meet above-mentioned requirements.
After reagent fills up quantitative pond 12, continue to flow to pond A13.The reagent flowing in the A13 of pond still has separate
The movement tendency of cd centre can be flow in the B14 of pond from pond A13.Pond B14 in addition to other than the junction of pond A13, it is equal with face
For sealing surface, reagent can not escape after entering pond B14.
Then CD rotates backward, and reagent starts to flow out out of reagent 11, flow in cache pool 3 by conduit C4.
Description below is gone out for the movement at this:
When CD rotates backward, reagent is flowed out out of quantitative pond 12 under the influence of centrifugal force, while the reagent in the B14 of pond
It is blocked, can not flow in quantitative pond 12.Reagent has the movement tendency opposite with CD rotation direction, and conduit C4 has just at this time
The good rear for being located at quantitative pond 12, reagent start to flow to conduit C4.
At this point, still remain a large amount of reagents in conduit A21, U-tube 22 and conduit B23, the pressure of reagent offer, quantitative pond
The pressure that air provides in the centrifugal force and pond A13 that reagent is subject in 12, three's collective effect push the reagent in quantitative pond 12
It is flowed to conduit C4.Reagent is flowed ultimately to after conduit C4 in cache pool 3.
Meanwhile the distance with the junction of U-tube 22 and conduit B23 compared with 22 junction of U-tube, apart from cd centre
It is farther, therefore conduit A21 and the pressure of the junction of U-tube 22 are bigger.The diameter of especially conduit A21 is far longer than U-tube
The diameter of 22 and conduit B23, have also been formed simultaneously fluid-tight in conduit A21, and the two collective effect prevents reagent from flowing backwards.
Because needing to add different reagents when blood testing, different reagents needs to be added between timesharing, therefore especially increases
Cache pool 3 is added, has been able to extend reagent and enters the time of reaction tank, to realize that the difference of time is added in different reagents.
The effect of surge pipe 5 is to be discharged to air extra in cache pool 3 when reagent flows into cache pool 3 on cache pool 3
It in atmosphere, avoids generating back pressure, reagent inflow is made to be obstructed.The effect of delivery line 6 is Connection Cache pond 3 and final reaction tank,
It introduces an agent into reaction tank.
In order to guarantee air pressure balance, barometric pipe 7 is also especially increased in reagent 11.Because with the stream of reagent
Out, the pressure reduction in reagent 11, can be lower than external atmosphere pressure, and the outflow of reagent is obstructed.The effect of barometric pipe 7 be by
Outside air is imported into reagent 11, makes up the pressure loss caused by reagent outflow.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations,
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that,
It can still modify to technical solution documented by previous embodiment, or be equal to part of technical characteristic
Replacement, and these are modified or replaceed, the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
