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 3 and quantitative pond 21 etc. are using molding
Production, diversion pipe 11 and conduit 23 etc. are integrated on a CD using accurate die pressing or etching production.
In use, suitable reagent is injected reagent 3, centrifugally operated equipment drives CD rotation, and reagent is in centrifugal force
Under the action of flow in quantitative pond 21 by diversion pipe 11.The simplicity of operation is further increased at this, CD is being made
Reagent can be made into packet to be potted directly into reagent 3 when making, when use punctures or the pressure by reagent to packaging bag
Break it automatically.
Diversion pipe 11 is connect with the lateral surface in quantitative pond 21, under the influence of centrifugal force, reagent will quantify from outside to inside
It fills in pond 21.After quantitative pond 21 is filled, extra reagent is transferred in run-off 22 by conduit 23.Diversion pipe 11 and overflow
The junction in pond 22 is closer to cd centre, and the pressure of reagent is on the direction for flowing to run-off 22 in such diversion pipe 11
It gradually decreases, reagent is enable smoothly to flow into run-off 22.Meanwhile run-off 22 can make closer to cd centre
Diversion pipe 11 and the fluid pressure of 22 junction of run-off are consistently less than quantitative pond 21 and the fluid pressure at diversion pipe 11, avoid
Reagent when reagent is flowed out from quantitative pond 21 in run-off 22 also flows out therewith, and acquisition precision is caused to decline.
Reagent from outside to inside during quantitative pond 21 is filled, the air in quantitative pond 21 is extruded to run-off
In 22.With the rotation of CD, bubble that may be present can also be precipitated and be eventually transferred into run-off 22 in reagent, exist in this way
It carries out that the bubble in reagent can also be removed when quantitative collection simultaneously, guarantees acquisition precision.
Quantitative pond 21 is leading flank close to the face of cd centre, is trailing flank far from the face in CD.Leading flank and rear side
Face is all made of cambered surface design, and center of arc is overlapped with the center of CD, can guarantee that reagent uniformly divides in quantitative pond 21 in this way
The gas for playing internal is all expressed in run-off 22 by cloth.Design is also for guarantee acquisition precision at this.
The minimum range of run-off 22 and cd centre is less than the minimum range in quantitative pond 21 and cd centre, in this way can
Guarantee that the air pressure in quantitative pond 21 is consistently higher than the air pressure in run-off 22, when the gas in quantitative pond 21 is shifted to run-off 22
When, it is not in resistance.
During entering quantitatively pond 21, the atmospheric pressure in connecting tube 31 and quantitative pond 21 is greater than conduit 23 and determines reagent
Measure the atmospheric pressure of 21 junction of pond.Therefore, reagent can be gradually filled with quantitative pond 21 rather than flow out from connecting tube 31.
Make description below for pressure: connecting tube 31 and the atmospheric pressure in quantitative pond 21 are provided by fluid stopping pipe 32, conduit
23 are mainly provided by conduit 23 with the atmospheric pressure for quantifying 21 junction of pond.Connecting tube 31 and conduit 23 are connected with the external world,
It is exactly medium in the two is air, under the influence of centrifugal force, pressure is free air lift to supply.The pressure formula P of reference fluids=
ρ gh, in the identical situation of ρ and g, the size of pressure is determined by h.On the direction close to cd centre, connecting tube 31 and lead
When the diameter of pipe 23 is identical, when the length of connecting tube 31 is greater than the length of conduit 23, connecting tube 31 and quantitative 21 junction of pond
Atmospheric pressure will be greater than the atmospheric pressure of conduit 23 and quantitative 21 junction of pond.In actual product, connecting tube 31 and lead
Pipe 23 diameter is close, on the direction close to cd centre, the length of connecting tube 31 is far longer than the length of conduit 23, is exactly
In order to guarantee existing always for pressure difference at this.
Run-off 22 also external an exhaust pipe 5, the free end of exhaust pipe 5 are connect with atmosphere, can make overflow in this way
Air pressure in pond 22 maintains an equal level with atmospheric pressure always, avoids generating back pressure in run-off 22 in quantitative collection.
After the completion of quantitative, CD is rotated backward, and the reagent in quantitative pond 21 is opposite with CD rotation direction with one
Movement tendency, under the influence of centrifugal force, reagent sequence pass through connecting tube 31, fluid stopping pipe 32 and delivery line 33 and are transferred to rear
In mixing pit or mixing apparatus, subsequent detection work is carried out.
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.
