Description
Technical field
The utility model is related to the field of medical instrument technology, and in particular to a kind of blood constituent preparative centrifugation balancing device.
Background technology
When center blood station prepares blood constituent, the method for generally use centrifugation, before prepared by centrifugation, in order to ensure centrifuge
Normal operation, weight demands are equal when each group of opposite blood bag centrifugation, and error range is no more than 5g, because of different people
Blood viscosity is different, and weight also differs, so ingredient needs to carry out trim operation to blood before preparing；Conventional method is
One group of blood bag staggered relatively is placed on the pallet of balance, is then placed sequentially in trim object according to the reading difference of balance
Trim is carried out on balance on goods and services, until the weight of two pallets is consistent, two parts of blood bags are connected to trim object is put into centrifuge together
Relative position is hung in cylinder, then carries out the trim of next group of blood bag again.
In conclusion there are following defects for the prior art：
1, blood bag trim error requirements are stringent (within 5g), and trim species are more and weight can not be predicted, and need to adjust repeatedly
It is whole just to can ensure that trim, time-consuming and laborious, inefficiency；
2, it is the small articles of small volume to also have some trim objects, is put into the gap for hanging cylinder after trim, it is easy to because of position
Set it is anti-set it is improper cause the effect when high speed centrifugation rotate because of centrifugal force to cause breakage to blood bag, cause to scrap, pollute from
Scheming；In addition, the use of small articles easy tos produce centrifugation dead space in centrifuge high speed rotation, showing for blood bag centrifugation breakage occurs
As influencing the quality safety of blood；
3, existing trim object also has carries out trim using liquid, first pours into container liquid, is placed on light-weight
On the pallet of side, according to weight difference, the water in container is bit by bit discharged, until being equal in weight in the pallet of both sides,
Although the time is saved in such method trim, because liquid needs to be discharged, next time with usually needing to draw liquid into again, operates
Inconvenience, while being discharged and also will produce leakage, waste of resource when sucking.
