The blood preparation pipe is put upside down vortex mixer
Technical field
The utility model relates to a kind of blood evenly mixing device, and particularly a kind of blood preparation pipe is put upside down vortex mixer.
Background technology
In blood station and medical institutions field,, before blood testing, need the blood preparation mixing in order to obtain blood testing result accurately.Along with social development, blood vacuum specimen tube collect specimen method has replaced traditional blood collection needle mode gradually.Adopt blood vacuum specimen tube to gather blood, especially when being added with different anti-coagulants or set accelerator in the pipe, requirement to mixing is more strict, by existing industry standard requirement, adopt artificial mixing to need back and forth to put upside down the specimen tube of erectting about 8 times back and forth with hand, this operation has strengthened operating personnel's work load, simultaneously brings harm easily because of blood overflows the infection that causes the operator to the operator because of artificial mixing; Simultaneously also cause cross pollution easily, cause detecting inaccurate.At present, the motor-driven blood vortex mixer of employing is arranged also, this class vortex mixer is generally tumbling-type vortex mixer and rotary vortex mixer.Wherein the tumbling-type vortex mixer is that the blood preparation pipe is horizontally-arranged, rolls by motor-driven blood preparation pipe and rotates, and realizes the blood mixing; This tumbling-type blood vortex mixer can not reach the industry standard requirement that the specimen tube of erectting is back and forth put upside down back and forth because of the horizontally-arranged rolling of blood preparation pipe, and blood mixing effect is undesirable.And rotary vortex mixer is that the blood preparation pipe is inserted in by on the motor-driven swivel mount, the blood preparation pipe is vertical with motor shaft, the blood preparation pipe is fixedly clamped by the holding force that the rubber sleeve that is provided with in the jack on the swivel mount produces after crimp, drives Guan Xiangyi direction rotation of blood preparation by the motor rotation and realizes the blood mixing; Yet this rotary vortex mixer is that because rotatory inertia can not reach the industry standard requirement that the specimen tube of erectting is back and forth put upside down back and forth equally, blood mixing effect is undesirable equally to a direction rotation.And this vortex mixer also easily when specimen tube inserts rubber sleeve because of extrusion friction makes the tag damage of pasting on the specimen tube, comes off, cause testing result confused; And the rubber sleeve of fixed preparation pipe is also aging easily, can cause specimen tube fixing not tight after rubber sleeve is aging, specimen tube be dropped, the working environment that contaminated blood detects when vortex mixer is worked from swivel mount, cause the staff to be infected, have a strong impact on the blood testing job security.
