Description
Technical field
The invention belongs to medical test equipment technical fields, and in particular to a kind of blood sample mixed well device.
Background technique
Medical clinical laboratory needs to carry out analysis detection to whole blood sample, is medical diagnosis on disease to obtain the detection parameters of sample
Or health examination provides judgment basis.Currently, blood examination is very widely used, it is conventional that vein is acquired using vacuum blood collection tube
Blood sample contains anti-coagulants in heparin tube, after sampling, mixes, be placed on rack for test tube first；Before detection, it is also desirable to carry out blood
The mixing of sample.In general testing laboratory, whole blood sample generally uses thumb and the third finger to pinch test tube both ends, with index finger and
Middle finger is fixed, and is overturned 4 times ~ 6 times, is detected again after blood sample mixed well.Without mixing, the accurate of testing result can be significantly affected
Property.Some detections then need to mix well blood sample repeatedly, in situation to be detected for multiple samples, need testing staff by
It is a to be shaken up, it is very time-consuming, laborious.
Currently, there is some improved blood-taking tube supports, this rack for test tube can move integrally or shake multiple blood sampling examinations
Pipe.Such as Chinese patent CN 201220424068.9 discloses a kind of box-packed blood-taking tube support, including box body, on the box body
Equipped with box cover, the outer two sides of the box body are equipped with handle, baffle are equipped in the box body, the baffle is equipped with jack, described

The up and down motion frequency of heparin tube in pipe fixed bin mixes desired blood sample for different, can flexibly use different shake instead
Uniform velocity realizes different mixed effect；For can not acute strong shake Oscillating blood sample, drive rod revolving speed is transferred to compared with low velocity, is mixed
Even 5 times；For the sample for needing thoroughly to mix, drive rod revolving speed can be transferred to fair speed, mixed multiple
Embodiment 4:
It is in place of the present embodiment and the main distinction of embodiment 1: as shown in Figure 3 and Figure 4, in blood sample mixed well device, heparin tube
Heparin tube rack 11 is fixedly installed in fixed bin 1, heparin tube rack 11 includes upper pallet 111 and lower pallet 112, pop-up
Plate 111 and lower pallet 112 are connected by front end panel 113 and rear bearing sheet 114, corresponding on upper pallet 111 and lower pallet 112
Be equipped with test tube hole 115 at position, each test tube can by upper pallet and lower pallet, two test tube holes being oppositely arranged it is total
It is fixed with vertical, 115 inward flange of test tube hole has flexible fastening pad 116.
In this blood sample mixed well device, heparin tube rack in heparin tube fixed bin, test tube hole inward flange thereon has
Flexible fastening pad, it can be ensured that vacuum blood collection tube is closely fixed in heparin tube rack, is prevented during shaking up, blood sampling
Pipe deviates from test tube hole.
Using Cam Design vibrating mechanism in this blood sample mixed well device, when the motor rotation in vibrating mechanism,
The round bar rotation of drive rod is driven, cross-bar rotates simultaneously, and band moving cam rotates, the edge setting multiple arcs protrusion of cam,
The height of protrusion is different, and vibrating effect is also different.The design of multiple arcs protrusion makes motor per revolution with regard to achievable multiple
Vibration improves the efficiency that vibration mixes.The round end of mandril alternately slides between two adjacent arc convex each time, when
When round end is in arc convex apex, mandril pushes up heparin tube fixed bin, when round end is between two arc convex
When recess, mandril drives downwards heparin tube fixed bin to fall after rise, completes primary vibration up and down each time and mixes, mixes effect each time
Fruit seemingly, for blood examination will not bring significant difference, can substitute testing staff and manually mix work.
Blood sample mixed well device specific work process of the invention is as follows:
1, vacuum blood collection tube is put into the test tube hole of heparin tube rack, heparin tube rack is fixed on heparin tube fixed bin
In, close the door of heparin tube place position.
2, power supply is opened, is required according to the mixing of sample to be detected, governor is adjusted, controls the revolving speed of motor to suitable speed
Rate.
3, drive rod starts to rotate under motor output shaft drive, when the round end of mandril each time alternately slides into two phases
Between adjacent arc convex, when round end is in arc convex apex, mandril pushes up heparin tube fixed bin, at round end
When recess between two arc convex, mandril drives downwards heparin tube fixed bin to fall after rise, and it is convex that cam is circumferentially with 4 arcs
When rising；For each revolution, heparin tube fixed bin moves up and down 4 times motor shaft.
4, it recycles by this process, can stop until reaching and mixing requirement.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
