Reversible micro-fluidic chip clamp

Abstract

The invention discloses a reversible micro-fluidic chip clamp. The reversible micro-fluidic chip clamp comprises a base, a supporting table and a clamp body, wherein the supporting table is arranged above the base; the clamp body is fixedly arranged on the supporting table; a groove is formed in the middle of the clamp body; U-shaped clamping grooves are symmetrically formed in the two sides of the groove; upper pressing plates and side pressing plates are movably arranged in the two U-shaped clamping grooves; a plurality of second threaded rods are inserted into the left side and right side of the top of the clamp body from front to back in a threaded manner; the lower ends of the plurality of second threaded rods on the same side are all rotatably connected to the upper pressing plate close to the lower ends of the plurality of second threaded rods; two sliding rods are symmetrically inserted back and forth on each of the two sides of the clamp body in a sliding manner; one end, inside the clamp body, of each sliding rod is fixedly connected to the corresponding side pressing plate close to the end; two telescopic rods are symmetrically arranged at the bottom of the groove; and asupporting plate is fixedly arranged at the upper end of each telescopic rod. The reversible micro-fluidic chip clamp is suitable for micro-fluidic chips of various specifications and adopts the omnibearing fixing mode of 360 degrees, the firmness is high, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a reversible microfluidic chip fixture. Background technique [0002] Microfluidic chip technology integrates the basic operation units such as sample preparation, reaction, separation, and detection in the process of biological, chemical, and medical analysis into a micron-scale chip, and automatically completes the entire analysis process. It has developed into a new research field interdisciplinary of biology, chemistry, medicine, fluid, electronics, materials, machinery and other disciplines. [0003] Microfluidic chips have the advantages of small size, less use of reagents, and high integration. More and more researchers have begun to pay attention to microfluidic chips. Gluing, this type of connection method is an irreversible connection, resulting in the inability to disassemble the microfluidic chip, high cost, and also affects follow-up observations. However...

[0003] Microfluidic chips have the advantages of small size, less use of reagents, and high integration. More and more researchers have begun to pay attention to microfluidic chips. Gluing, this type of connection method is an irreversible connection, resulting in the inability to disassemble the microfluidic chip, high cost, and also affects follow-up observations. However, the traditional microfluidic chip fixture has a single connection method and complex operation, and the firmness Poor, at the same time, it does not have adjustability, which brings inconvenience to the test work. Therefore, the present invention proposes a reversible microfluidic chip fixture to solve the above problems
