Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a disc-type multi-channel ultrasonic sample processing device. Background Art

[0002] In the field of in vitro diagnostics, pre-treatment methods such as mixing and crushing samples using ultrasound have been widely used. Due to the unique mechanical and cavitation effects of ultrasound itself, it has higher efficiency and stronger crushing properties in sample processing compared to traditional mechanical methods. Its own adjustment function makes this method more controllable and is considered to be a more effective processing method.

[0003] Although the probe-type ultrasonic treatment directly puts the ultrasonic probe deep into the sample to solve the problems of high energy consumption and long processing time, it will cause contamination of cell sample safety and have a great impact on the precision of cell detection. The traditional non-contact ultrasonic cell treatment directly puts the ultrasonic probe against the outer wall of the centrifuge tube, or transmits ultrasound to the sample pool through the plastic of the centrifuge tube. In this way, the temperature of the sample is not easy to control. The water tank liquid conduction treatment has many disadvantages such as long processing time, high energy consumption, uneven sample processing, low efficiency, and small processing volume. The water-soluble ultrasonic method puts the sample to be processed directly into the ultrasonic water tank. When the ultrasonic vibrator is working, the mist emitted by the solution will fly into the sample, affecting the precision of the sample processing. Because it needs to be placed in the water tank for processing, the energy consumption is high, the container is large, the conduction time is slow, and the efficiency is low.

[0004] Therefore, to address the above problems, we propose a disc-type multi-channel ultrasonic sample processing device. Utility Model Content

[0007] As a further description of the present invention: the reagent tube mold is made of rubber, and the inner wall is provided with test tube grooves for inserting the reagent tubes. The number of the test tube grooves is multiple groups and distributed in a circle around the inner wall of the reagent tube mold, and the inclination angle of the test tube grooves is 15°.
