Abstract
The utility model provides a sample sending device capable of automatically and uniformly mixing a blood sample, which realizes uniform mixing and puncture sampling functions on a measurement instrument. The sample sending device comprises a drive motor, a transmission device, a rotation device and a sample storage disc, wherein a sensor controls the motor to rotate, and the sample is automatically sent to a sampling position. The sample sending device is capable of achieving the effect of uniformly mixing the blood, and also realizing the purpose that the samples are automatically sent in batch.
Description
Technical field
The utility model relates to a kind of mixing blood sample automatically, and is used the device that sample is sent in realization automatically with the blood testing instrument.
Background technology
In clinical medical inspection, every detection of carrying out blood at first can be in order to obtain accurately assay and with the blood sample mixing.Because it is strong and than characteristic such as great that red blood cell has an aggregation, static mobile blood can begin natural subsidence, layering after placing a period of time.And existing mixing technology is for handling up mixing and put upside down mixing, the greatest problem that the mixing of handling up exists be mixing time long, easily pollute etc.Therefore this kind method is superseded substantially.
Existingly shake up device substantially all is used to reach robotization with detecting instrument effect, but relative merits are separately still arranged separately.Do circumference and rotate such as drive test tube by ferris wheel, allow test tube turn to finish once inside out after a week and put upside down.The shortcoming of this kind device is that its occupation space is bigger, if the sample size on the ferris wheel is more many, the height of ferris wheel will be more high so, thus the height of lifting entire machine; Level concussion formula vortex mixer uses the stepper motor rotating to reach the simulation test tube and waves and reach the mixing effect, and the shortcoming of this kind device is that noise ratio is big and mixing is insufficient; The most reliable also is state-of-the-art surely belonging to use mechanical arm to overturn, but its cost substantially exceeds additive method.
Summary of the invention
For overcome existing evenly mixing device cost height, the deficiency such as big that takes up room, the utility model is provided at the automatic mixing sample conveying device of realizing mixing and puncture sampled functions on the surveying instrument.Not only can reach the effect of mixing blood, and can also automatically next sample be delivered to the sampling location, realize the robotization batch detection.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of sampling device of automatic mixing blood sample, described sampling device comprises the motor frame, be installed in drive motor, support on the described motor frame, be installed in gear train, wheelwork and sensor on the described support, described drive motor drives described gear train and rotates, described sensor is connected with controller with drive motor, and whether the signal controlling drive motor that described sensor sends rotates.
Described gear train, rotating mechanism and sensor are installed on the described support.This support and described motor frame together are installed on the surface level, be positioned at the puncture sampling probe under.
The beneficial effects of the utility model are: structure is concisely compact, and the design of its blood sample tray can be saved sizable space; Realize sample mixing and sample presentation in batches, operate steadily, practical reliable, significantly shortened the time of mixing blood sample operation to be measured, fully improved work efficiency and the check accuracy of detecting instrument; Use worm and gear as gear train, efficiently solve the generation of noise in conjunction with its drive characteristic, and himself with auto-lock function also exempt the power consumption that the drive motor self-locking brings fully, implemented the theory of low-carbon environment-friendly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the perspective view that the utility model axle is surveyed the visual angle.
Fig. 2 is the utility model top perspective structural representation.
Fig. 3 is the synoptic diagram of the supporting specimen holder of the utility model.
1. bearings among the figure, 2. bearing holder (housing, cover), 3. bearing, 4. spring coupling, 5. drive motor, 6. motor frame, 7. specimen holder, 8. blood sample tray, 9. geometrical clamp, 10. geometrical clamp spanner, 11. turning axles, 12. position transducers, 13. worm screw, 14. worm gears, 15. puncture positions, 16. position locator, 17. anticoagulant tube putting holes, 18. put upside down the position.
Embodiment
In Fig. 1, bearing (1) and motor frame (6) are installed on the blood testing instrument apart from level with certain location, drive motor (5) is fixed on the motor frame (6), be connected with worm screw (13) with spring coupling (4), wherein, worm screw (13) two ends install bearing (3) and install bearing holder (housing, cover) (2) again, and are fixed on the bearing (1), and the position of bearing holder (housing, cover) (2) can be finely tuned.
In Fig. 2, worm gear (14) and turning axle (11) are installed together, and are fixed on the bearing (1), and the position of regulating shaft bearing sleeve (2) is to eliminate the assemblage gap between worm gear (14) and the worm screw (13).Geometrical clamp (9) is installed on the blood sample tray (8).Go up ad-hoc location at bearing (1) and install position transducer (12).
When need detecting, the blood sample tray (8) that installs blood sample is inserted on the turning axle (11), with geometrical clamp spanner (10) folder (9) that is locked, blood sample tray (8) and turning axle (11) is fixed, allow it can't produce relative motion.Start drive motor (5), when drive motor (5) rotates, the spring coupling that is attached thereto (4) can drive worm screw (13) and rotate, the rotation of worm screw (13) is passed to turning axle (11) by worm gear (14), turning axle (11) drives blood sample tray (8) again and rotates, when position (18) was put upside down in rotation arrival, sample was realized putting upside down once, reaches the mixing effect repeatedly several times.When blood sample arrived puncture position (15), position transducer (12) can send signal and give controller, and controller control drive motor (5) stops operating.Thereby make the anticoagulant tube that blood sample to be measured is housed rest on puncture position (15).By the time finish after the sampling of a sample, controller can be controlled drive motor (5) and be rotated further, wait next sample to arrive puncture position (15) after, position transducer (12) can send signal again and give controller, control drive motor (5) stops operating.So just realized the function of sample automatic sample conveying detection in batches.And after drive motor (5) stopped operating, the latching characteristics of worm gear (14) and worm screw (13) can make whole blood sample tray (8) not rotate in puncture, has guaranteed the reliability of whole device.
