First embodiment

Fig. 1 is a schematic structural diagram of a first view angle of a blood sample mixing device according to an embodiment of the present disclosure; fig. 2 is a schematic structural diagram of a second view angle of the blood sample mixing device according to the embodiment of the present disclosure; fig. 3 is a sectional view of section a-a of fig. 2. As shown in fig. 1 to 3, a first embodiment of the present application provides a blood sample mixing device, which has the following specific structure:

the blood sample mixing device comprises a rotary table 30, a base 10 and a test tube mounting piece 40. The base 10 is a wedge-shaped structure, and includes a bottom surface 101 and a mounting surface 102.

The turntable 30 is provided on the mounting surface 102 of the base 10, and the turntable 30 is rotatable about a rotation axis 301 of the turntable with respect to the base 10; the axis of rotation 301 of the turret makes a first angle with the bottom surface 101.

At least one test tube mounting member 40 is arranged on the turntable 30, and a second included angle is formed between the rotating shaft 301 of the turntable and the central shaft 401 of the test tube mounting member.

Wherein, the first included angle and the second included angle are acute angles, and the sum of the first included angle and the second included angle is 90 degrees.

The rotation of the turntable 30 may be manually performed, but in a more preferred embodiment, a driving mechanism 20 for driving the turntable 30 to rotate may be provided on the base 10, an output shaft of the driving mechanism 20 is connected to the center of the turntable 30, and an output shaft of the driving mechanism 20 is collinear with the rotation axis 301 of the turntable.

For the sake of convenience in the following description, a first included angle α (not shown) and a second included angle β (not shown) are provided, and a third included angle γ (not shown) exists between the bottom surface 101 and the mounting surface 102 of the base 10. According to the geometric relationship, γ ═ β ═ 90 ° - α.

During the use, insert the test tube 50 that contains blood sample and locate on test tube installed part 40, the bottom surface 101 of base 10 is parallel with the horizontal plane, and actuating mechanism 20 drive revolving stage 30 is rotatory to it is rotatory to drive test tube 50. Since the rotation axis 301 of the turntable forms a first angle α with the bottom surface 101, the test tube 50 has a first position W1 where the horizontal position is the lowest and a second position W2 where the horizontal position is the highest during the rotation.

When the test tube 50 is at the first position W1, the test tube 50 is in an inclined posture, and an included angle between the central axis 401 of the test tube mounting member and the vertical direction is 2 β, that is, an acute angle of 90 ° -2 β exists between the liquid level 501 in the test tube 50 and the central axis 401 of the test tube mounting member; and when the turntable 30 reaches the second position W2 after rotating 180 °, the central axis 401 of the test tube mounting member at this time is perpendicular to the horizontal plane, and the liquid level 501 in the test tube 50 is in a perpendicular relationship of 90 ° with the central axis 401 of the test tube mounting member at this time, that is, in the rotating process of the turntable 30, the liquid level 501 in the test tube 50 has an angle change of 2 β, so that when the turntable 30 rotates at a certain speed, and under the influence of atmospheric pressure in the test tube 50, the blood sample can be irregularly disturbed in the test tube 50, thereby achieving the effect of uniformly mixing the blood sample, and solving the problem of layered sedimentation of the blood sample.

The second angle β should not be too large, since the space between the liquid level 501 in the test tube 50 and the cap of the test tube 50 is limited. Through a plurality of tests, the effect is better when the value of the first included angle alpha is 60-83 degrees, and at the moment, the value of the second included angle beta is in the range of 7-30 degrees.

That is, when the test tube 50 is in the first position W1, the angle between the central axis 401 of the test tube holder and the vertical direction is 14 ° to 60 °.

In a more preferred embodiment, the first included angle α is 66 ° to 78 °, the second included angle β is 12 ° to 24 °, and at this time, the included angle between the liquid level 501 in the test tube 50 and the central axis 401 of the test tube mounting member is not too small, and the uniform mixing effect can be ensured.

Still preferably, the first angle α is 75 ° and the second angle β is 15 °.

In order to improve the blending efficiency, the driving mechanism 20 usually employs a motor, and an output shaft of the motor is fixedly connected to the center of the turntable 30.

In a more preferred embodiment, a plurality of test tube mounts 40 are circumferentially arranged on different radii along the edge of the turntable 30, and the test tube mounts 40 on different radii are circumferentially offset from each other. For example, 28 test tube mounts 40 are arranged in two inner and outer circles of different radii, 4 sectors, and the test tube mounts 40 of the inner and outer circles are again staggered circumferentially from each other to facilitate bar gun scanning.

To ensure stability of the turret 30 during rotation, the test tube mounts 40 are typically arranged axisymmetrically with respect to the axis of rotation 301 of the turret.

In order to improve the efficiency of single mixing, the test tube mounting member 40 can be arranged in dozens or even more, and at this time, the inner layer and the outer layer can be arranged.

In other embodiments of the present embodiment, the tube mount 40 is generally a cylindrical holder, which facilitates the insertion and extraction of the tube 50. More preferably, a notch extending along the length direction of the cylindrical support is formed in one side wall of the cylindrical support, so that the cylindrical support has larger deformability, and the test tube 50 can be inserted and pulled out more conveniently.

Simultaneously, the position and the size of this notch match with the bar code on the test tube 50 to make things convenient for the bar code rifle to scan the information of gathering test tube 50.

In the preferred embodiment of this embodiment, a plurality of mounting positions may be provided on the turntable 30, and the test tube mounting members 40 are detachably provided in the mounting positions, so that the number and positions of the test tube mounting members 40 can be conveniently adjusted.

Specifically, the sensor may employ a micro switch, and the light emitting device may be an led light strip or an indicator light, disposed on the outer wall of the tube mounting member 40 or disposed around the outer bottom of the tube mounting member 40.

During the use, whether the sensor detects test tube 50 in the test tube installed part 40 to feed back the result to control circuit board, control circuit board combines other external information again, controls light emitting device's work.

For example, a cuvette 50 is inserted into a certain cuvette mount 40, such that it first triggers a micro-switch, when the light emitting device is not lit; after the uniform mixing, the test tube 50 is taken away for sampling, at the moment, the microswitch is reset, and the luminescent device is still not bright; after sampling, the test tube 50 is inserted into the test tube mounting piece 40 again, the microswitch is triggered for the second time, and at the moment, the light-emitting device is electrified and emits light to prompt a worker that the sampling in the test tube 50 is finished; after the staff takes out this test tube 50, micro-gap switch resets, and the luminescent device goes out. After the next test tube 50 is inserted, the above process is repeated, so that the worker can be informed conveniently and accurately which test tubes 50 have the samples in the sampling step completed.

The light emitting device may be a monochromatic light or a polychromatic light, and the color of light emitted by the control circuit board controller displays different states of the cuvette mounting member 40.
