Description
Technical field
The present invention relates to a kind of centrifuge rotor, especially relate to a kind of preparing washing red blood cell centrifuge rotor.
Background technology
Washed Red Blood Cells are composition blood transfusion products that surgery is conventional.That healthy blood is removed whole blood plasma and 90% leucocyte and the later goods of blood platelet.Clinical in produce the anaemia patient of leukocyte antibody because repeatedly transfusing blood, and patient after organ transplant, rejection reduced.First whole blood separates blood plasma and removes leucocyte after centrifugal under aseptic condition, in red blood cell, add SPSS to mix, the remaining leucocyte of centrifugal removal again, so cyclic washing is finally removed more than 98% blood plasma 3 times, more than 90% from cell, blood platelet, also remove the metabolites such as the potassium that produces in preservation process, ammonia, lactic acid simultaneously, retained 70% above red blood cell, finally added physiological saline suspension.
The centrifuge using for the preparation of Washed Red Blood Cells process at present, the time that general rotating speed is raised to 4700rpm from 0rpm needs the time more than 60S, and when current centrifugal rotor is used, dismounting is inconvenient, complex structure, security is poor, and therefore a kind of use reliably, rotor has clear superiority for preparing washing red blood cell easily.
Summary of the invention
Object of the present invention is exactly to provide a kind of simple in structure, easily manufactured, safe and reliable preparing washing red blood cell centrifuge rotor in order to overcome the defect of above-mentioned prior art existence.
Object of the present invention can be achieved through the following technical solutions:
A kind of preparing washing red blood cell centrifuge rotor, be arranged on the driving shaft of centrifugal motor, described rotor is in the form of annular discs, the center of rotor is offered as pivot hole, the outer of rotor offers centrifuge tube draw-in groove, the number of this centrifuge tube draw-in groove is even number, symmetrical with respect to pivot hole between two, on two inwalls of described centrifuge tube draw-in groove, offer respectively for hanging the rotor pinhole of centrifuge tube, the centrifuge tube that is provided with centrifuge tube pinhole is suspended on rotor pinhole by pin.
In described pivot hole, be provided with the bayonet socket axially engaging with centrifugal motor.
When making centrifuge tube static, the angle that described rotor pinhole is offered becomes 35 degree angles with pivot.When turning round, centrifuge tube becomes miter angle with pivot.
Described centrifuge tube draw-in groove is preferably 12.
Described rotor is fixedly formed by screw by upper rotor part and lower rotor part, and described upper rotor part and lower rotor part are moulding.
The centrifuge tube symmetry that equivalent test solution is housed is placed in the Centrifuge Cup of rotor surrounding, after starting the machine, motor rotor driven the produced RCF (RCF) that runs up makes test solution separated, the size of RCF depends on that the horizontal range in the residing position of sample to axle center is radius of turn r and rotation speed n, and its computing formula is as follows:
RCF＝1.118×10
-5n
2r×g
Wherein, n be rotating speed (rev/min), r be radius of turn (centimetre);
Separate particles in mixed liquor, precipitate required time T s and calculated by following formula:
Ts=27.4 * (log

In formula: ρ be mixed liquor density (gram/cc), μ is viscosity of mixed liquid (pool), n be rotating speed (rev/min), r be particle radii (centimetre), σ be particle density (gram/cc), R
maxfor the horizontal range in the end to the axle center of centrifugal test solution (centimetre), R
minfor the face of centrifugal test solution to the horizontal range in axle center (centimetre).
During rotor of the present invention, maximum centrifugal radius is 7.5mm, and the maximum centrifugal force in the time of can calculating 4700rpm according to above formula is 1850g.
Compared with prior art, the present invention has the following advantages and beneficial effect:
One, easy to use: this rotor can directly be enclosed within on axle and rotate, do not need locking nut to lock just can to carry out centrifugal, reduced the step of manually tightening;
Two, safe and reliable: because its center of gravity under, therefore while rotating, can not depart from centrifugal shaft;
Three, reduce costs: injection mold one-shot forming, has reduced cost after production in enormous quantities.
