The rubber cap of stomata, blood is completely sealed in a device.It is put into centrifuge and sets parameter progress first time centrifugation.Equally
, the separator for filling blood is put into centrifuge, under the rotation of centrifuge, each component in blood is because of the work of centrifugal force
With and separate, in separator be layered, such as upper strata be serum, lower floor is red blood cell.At this point it is possible to by rotating under regulation
End cap, makes bottom end cover closer or far from the 3rd section, to reach the effect of adjustment separator internal capacity, was so adjusting
Cheng Zhong, makes the layering of blood at the blocking of stock shape block device and the first section or the 3rd section, then passes through rotation again
Turn corresponding section, lock stock shape block device B terminations.For example, rotation regulation bottom end cover, makes layering interfaces be located at the firstth area
Circular tapping in the middle of the conical baffle of section, then the first section of regulation and the second section are rotated, make the A of stock shape block device
Termination is withstood round hole, i.e. A terminations and locked, and circulation of the blood in separator is blocked at layering.Then just can be by
Upper strata component in blood is extracted.Certainly, in rotation the first section of regulation and the second section, due to the change of internal capacity
Changing may cause the position of layering to change, and now need to adjust bottom end cover again again and opened with recovering layering interfaces positioned at circle
At hole, if necessary need repeatedly to adjust repeatedly.
After upper strata component is extracted.It will can be reversed above and below separator, i.e., original bottom end cover is now placed in
Portion, recycles above-mentioned steps to be operated, and layering is located at the B ends of stock shape block device and then by stock shape block device
B terminations lock the 3rd section intermediate connection hole, stock shape block device B terminations locking.If necessary, long rod can be released
The lock-out state of the A terminations of block device makes blood be back to the volume space of upper end cover composition to adapt to the tune of blood layered position
Section.
Blood separating mechanism described in the utility model when A, B termination of stock shape block device are all in lock-out state,
Whole blood separating mechanism is to be blocked to be divided into 3 independent disconnected volume spaces.Each on blood separating mechanism
Internal thread or external screw thread are provided with enough number of threads and pitch, and ratio is stamped with each section or upper and lower end when rotated
Larger operating range, making each volume space in inside of blood separating mechanism has than larger adjustment excursion, adapts to blood
The separation of liquid component.
Although described above is each embodiment of the present utility model, however, it is to be understood that they are intended only as example to be in
Existing, and without limitation.For those skilled in the relevant art it is readily apparent that various combinations, change can be made to it
Type and change are without departing from spirit and scope of the present utility model.Therefore, width of the present utility model and model disclosed herein
Enclosing should not be limited by above-mentioned disclosed exemplary embodiment, and should be according only to appended claims and its equivalent substitution
To define.
