Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.

Referring to fig. 1-10, the invention includes a base 1, a rotatable housing 2 is disposed above the base 1, an annular cover 3 fixedly connected to the base is disposed inside the housing 2, a plurality of first rotating shafts 4 which are circumferentially and uniformly distributed and rotatable are disposed on a side surface of the housing 2, each first rotating shaft 4 outwardly penetrates the housing 2 and is fixedly connected with a positioning block 5, a plurality of pipe clamps 6 are fixedly connected to each positioning block 5, each first rotating shaft 4 inwardly penetrates the housing 2 and is fixedly connected with an overturning block 7, two small rollers 8 are rotatably connected to each overturning block 7, the small rollers 8 can contact and roll with the lower end edge of the annular cover 3 to keep the positioning blocks 5 horizontally rotating, two guide grooves 9 which can respectively cooperate with the two small rollers 8 to rotate the first rotating shafts 4 are disposed on the annular cover 3, and each guide groove 9 is formed by a first Y-shaped chute 901, A vertical slot 902 and a second diagonal slot 903.

When the device is used, collected blood collection tubes are fixed on the positioning blocks 5 through the tube clamps 6, then the shell 2 is rotated through the driving mechanism, in the rotating process of the shell 2, all the positioning blocks 5 can rotate along with the shell 2, in the rotating process of the positioning blocks 5, the two small rollers 8 can contact with the lower end edge of the annular cover 3 to keep horizontal rotation, when one small roller 8 enters the first chute 901, the other small roller 8 is still arranged at the lower edge of the annular cover 3, at the moment, the positioning block 5 can deflect by taking the small roller 8 entering the guide groove 9 as driving force, after the small roller 8 enters the vertical groove 902, the other small roller 8 can continuously deflect until the two small rollers 8 are in a vertical state, at the moment, the positioning block 5 is turned over 90 degrees, when the shell 2 continues to rotate, the positioning block 5 can continuously turn over until the small roller 8 in the guide groove 9 comes out of the second chute 903, the locating piece 5 at this moment will overturn 180 degrees, and the figure of the guide way 9 in this device is equipped with two, can also be four, six etc. even numbers, can get back to initial condition again after the heparin tube upset mixing on locating piece 5, the operation of being convenient for, this device casing 2 is in continuous pivoted in-process, and locating piece 5 also can follow and still can overturn when doing the rotation and carry out more abundant mixing to blood.

Further, in order to make the blood in the blood sampling tube mix more fully, improve the rate of accuracy of detection, every all the cover is equipped with first spring 10 on the first pivot 4, first spring 10 is between locating piece 5 and casing 2, the inside fixedly connected with fixed block 11 of annular cover 3, the outside edge fixedly connected with of fixed block 11 leads movable block 12 of continuous concave-convex form, lead movable block 12 and the position of guide way 9 and do not correspond, be equipped with on the gyro wheel 8 and lead movable block 12 cooperation messenger first pivot 4 along its axial reciprocating motion's guide rod 13.

When the positioning block 5 horizontally rotates by contacting the lower edges of the two small rollers 8 and the annular cover 3, the guide rods 13 on the two small rollers 8 can be matched with the continuous concave-convex guide block 12 to enable the positioning block 5 to do reciprocating motion along the axial direction of the first rotating shaft 4, after the convex part of the guide block 12 is contacted with the guide rods 13, the positioning block 5 moves outwards along the axial direction of the first rotating shaft 4, at the moment, the first paralysis 10 is compressed, when the contact point is transferred from the convex part to the concave part, the positioning block 5 moves inwards along the axial direction of the first rotating shaft 4 under the action of the first spring 10, and the reciprocating motion can realize the oscillation and uniform mixing of the blood sampling tubes on the positioning block 5.

In order to enhance the frequency of oscillation and realize the uncertainty of the amplitude of oscillation, a rolling ball 14 is embedded at one end of each guide rod 13, which is in contact with the guide block 12, and the two guide rods 13 are unequal in length. When the two guide rods 13 are unequal in length and have not great length difference, a longer or shorter guide rod 13 is just in contact fit with the guide block 12, at the moment, the oscillation amplitude is larger, the frequency is lower, after the two guide rods 13 are both in contact with the guide block 12, the longer guide rod 13 is likely to be in contact with the convex part, but when the longer guide rod 13 is switched from the convex part to the concave part, the shorter guide rod 13 can be in contact with the convex part, the oscillation frequency is enhanced, the oscillation amplitude is reduced, and finally the shorter or longer guide rod 13 is in contact with the guide block 12, so that the reciprocating motion is carried out, the blood sampling tube is uniformly mixed in multiple modes of rotation, overturning and oscillation, the blood can be sufficiently uniformly mixed in a shorter time, and the working strength of workers is also reduced.
