Description

technical field [0001] The invention relates to the technical field of liquid mixing, in particular to a suspension mechanical mixing device, and discloses a mixer using the mixing device. Background technique [0002] Currently used in the sample detection process, in order to ensure that the suspension in the sample or reagent does not settle for a long time, or to ensure that the suspension can be fully mixed during the detection process, it is necessary to continuously stir the sample or reagent to achieve a uniform state. The technical means to realize it are as follows: [0003] 1. The inner wall of the reagent bottle or reaction vessel is equipped with a stirring plate, which is driven by an external mechanism to rotate, and the protruding stirring plate on the inner wall plays a role in mixing. There is a stirring plate inside the bottle, and a gear structure and a transmission mechanism on the outside. The complex structure is difficult to process and high cost, so...

AI Technical Summary

Problems solved by technology

There is a stirring plate inside the bottle, and there must be a gear structure and a transmission mechanism on the outside. The structure is complex, difficult to process, and high in cost. It can only be used for reagent bottles.

[0004] 2. Adding a mechanical stirring rod requires adding a stirring mechanism and a cleaning mechanism. The cost is high, and the cleaning residue is easy to cause pollution

[0006] 4. Ultrasonic stirring, the ultrasonic waves emitted by the ultrasonic transmitter generate a driving force to stir the liquid, the ultrasonic transmitter has a complex structure and high cost, the ultrasonic transducer will attenuate and the replacement cost is high, a transfer medium is required, and the reaction cup or reagent bottle needs to be soaked In the solution, the energy of the ultrasonic mixing process is relatively large, and the bubbles generated will damage the biologically active substances. The bubbles generated during the process will not be drained cleanly in a short time, which will interfere with the detection.

[0007] 5. The remote mixer in the machine oscillates as a whole, requiring a mechanical arm to grab the reagent bottle or reaction cup to the mixer. The mechanical structure is complex, the cost is high, and the time extension affects the speed of the instrument.

[0008] 6. The overall upside-down mixing can only be realized by closing the lid, and the lid opening mechanism or puncture to take samples or reagents is required, which is slow, costly, and easy to pollute

[0009] 7. The overall small-scale vibration and mixing in the machine, the small-scale is difficult to fully mix, it needs to be mixed manually and added to the instrument to let it continue to vibrate, the mixing effect is not good for deeper liquids or slender containers

[0010] 8. Manually placed on the mixer outside the machine to mix, the process is cumbersome, and it is impossible to realize large-scale automatic operation

[0011] Manual oscillation and mixing outside the machine, the process is cumbersome, and it is impossible to realize large-scale automatic operation

[0012] The injection needle blows and mixes evenly, and the speed is slow, which is easy to cause cross-contamination. Small air bubbles are difficult to remove during the blowing process, which will interfere with the subsequent detection.
