Portable biochemical reactor

Abstract

The invention relates to a portable biochemical reactor, which is suitable for driving at least one stirring sleeve to move relative to at least one reagent box along a first axial direction and comprises a rack unit and a variable-speed lifting unit. The frame unit is adapted to support the at least one reagent box. The variable-speed lifting unit comprises a linear moving module, a variable-speed transmission module and a rotating module. The linear moving module is provided with a sliding block suitable for installing the at least one stirring sleeve, the sliding block moves between a top end position and a bottom end position relative to the rack unit, when the sliding block is located at the top end position, the sliding block is suitable for being far away from the at least one reagent box, and when the sliding block is located at the bottom end position, the sliding block is suitable for being far away from the at least one reagent box. The sliding block is adapted to be adjacent to the at least one reagent box. The variable-speed transmission module is provided with a transmission piece and a guide piece. The rotating module is used for driving the transmission part to rotate so as to drive the sliding block to move along the guide rail along the first axial direction and synchronously drive the at least one stirring sleeve to generate variable-speed linear movement.

Description

technical field [0001] The invention relates to a biochemical reactor, in particular to a portable biochemical reactor. Background technique [0002] Existing biochemical reactors using silica magnetic beads (Magnetic Beads) for nucleic acid extraction (Nucleic Acid Extraction), the purpose of which is to remove nucleic acids (DNA or RNA) from biological samples, and further provide them in, for example, polymerase chain reaction (PCR, Polymerase Chain Reaction) and other biological detection. [0003] When the biochemical reaction is in progress, in order to increase the extraction rate of nucleic acid, the biological sample and magnetic beads are repeatedly mixed with reagents of different functions by stirring, and the biochemical reaction procedures such as lysis, cleaning, and nucleic acid recovery are performed sequentially , and finally the purified nucleic acid is extracted. [0004] The above-mentioned stirring method is usually in the form of using a motor with a...

Problems solved by technology

In addition, because the motor needs to rotate several times to drive the screw to reach a certain travel distance, this makes the existing biochemical reactor have relatively large power consumption.

The combination of the motor and the screw will also make the overall equipment have a certain weight, which is difficult to lighten and is not conducive to portability.

[0005] Such shortcomings will make it difficult for existing biochemical reactors to be used in front-line occasions other than laboratories, such as aquaculture quarantine sites or forensic sites...etc.

And because of the high cost of the overall structure, it is also difficult to popularize, and there is room for improvement in use.
