Description
Technical field
The utility model relates to a kind of medicine equipment, particularly a kind of blood evenly mixing device.
Background technology
In medical domain, carrying out examination by blood testing to disease is a kind of common disorder in screening mode.Blood is made up of blood plasma and the haemocyte be suspended in wherein, and haemocyte comprises red blood cell, leucocyte and blood platelet.Existing blood test is usually got a certain amount of blood by vacuum test tube and is added anti-coagulants mixing, to carry out FBE or to prepare blood plasma.Existing evenly mixing device is distributed on a rotating disk by multiple vacuum test tube, mixed, once can realize the mixing of multiple vacuum test tube inner blood by the rotation of rotating disk and partially dynamic combined running mode.But this device power configuration is comparatively large, and energy consumption is high, and for single vacuum test tube, its rotating speed is low, inferior separating effect, and disengaging time is long.For this reason, need to improve.
Summary of the invention
The utility model object is for the deficiencies in the prior art, provides a kind of blood plasma evenly mixing device, should to be driven the mode of single vacuum test tube High Rotation Speed, and realize the mixing of blood, its energy consumption is low, good separating effect, efficiency is high by drive motor.
For achieving the above object, the utility model adopts following technical scheme.
A kind of blood plasma evenly mixing device, comprise the pallet that can rotate by multiple station, pallet is evenly distributed in multiple socket joint hole, each socket joint hole is used for correspondence and is installed on a vacuum test tube, vacuum test tube and socket joint hole form the rotatable matching relationship of coaxial cable, drive motor is provided with above pallet, the electrical axis of drive motor is positioned on the reference circle in socket joint hole, drive motor is connected with driving shaft by motor shaft, and the other end of this driving shaft and the rubber tube hat of vacuum test tube are shaped as friction-type torque transfer arrangement; Described pallet or drive motor are connected with the elevating mechanism to being applied to its lifting.
Adopt the utility model of preceding solution, when pallet turns to a station of setting, vacuum test tube axis in corresponding socket joint hole and drive motor axis are positioned on the same line, by elevating mechanism rising pallet or drive motor, the pipe cap of vacuum test tube are connected with the motor shaft of drive motor by friction clutch structure; Drive vacuum test tube to rotate by drive motor, the blood and the anti-coagulants that realize vacuum test tube mix.Because motor drives separately a vacuum test tube, therefore, its driving moment is little, and energy consumption is low, and Blending Efficiency of Blending is good, and efficiency is high.Wherein, friction clutch utilizes the pit at pipe cap top to be formed; After the blood of pallet in a vacuum test tube and anti-coagulants mixing, after elevating mechanism makes pallet decline or drive motor is raised, pallet turns to next station again, realizes mixing operation next time.
Preferably, the part described driving shaft is connected with described pipe cap is made up of elastomeric material.To utilize the feature that friction factor between elastomeric material is large, reduce normal pressure therebetween, thus reduce wearing and tearing at the bottom of vacuum test tube pipe, extend heparin tube serviceable life.
Preferably, described driving shaft is elastic extension structure.To form enough pressure between driving shaft and pipe cap, in order to guarantee that there is enough friction force therebetween, obtain to make vacuum test tube and mix rotation reliably.
Further preferably, described driving shaft comprises driving shaft main body, telescopic joint, is provided with cylindrical compression spring between driving shaft main body, telescopic joint, and driving shaft main body has traversed bearing pin, and telescopic joint is provided with the gain coordinated with described pin slide; Described torque transfer arrangement is located between telescopic joint free end and pipe cap.Simple to guarantee the structure of stretching structure, reduce manufacturing cost and use cost.
Preferably, the bottom in described socket joint hole is provided with nylon cushion.Utilize the antiwear characteristic of nylon and the lower feature of hardness, guarantee socket joint hole depth size retentivity, and avoid the pipe bottom of causing vacuum test tube to wear and tear.
The beneficial effects of the utility model are, disengaging time is short, good separating effect, and energy consumption is low, long service life, and manufacturing cost and use cost is low.
