Cell chemotaxis detection device

Abstract

The invention discloses a cell chemotaxis detection device, and belongs to the technical field of cell chemotaxis detection devices. The cell chemotaxis detection device comprises a base, a first sliding rail, a second sliding rail, a cell operating frame, a cell operating floor and a cell injection frame. The first sliding rail and the second sliding rail are fixedly connected to the base, the cell operating frame is slidably connected to the side, away from the base, of the first sliding rail and the second sliding rail, the cell operating floor is fixedly connected into the cell operating frame, and the cell injection frame is fixedly connected to the cell operating floor. The base is further fixedly connected with a first fixing assembly and a second fixing assembly. The cell chemotaxis detection device is simple in structure, and the concentration gradient formed by chemotactic factors and other sample samples in a flow path can be stably kept; and meanwhile, the working stability of the cell injection frame can be improved through cooperation of the first fixing assembly and the second fixing assembly.

Description

technical field [0001] The invention relates to the technical field of cell chemotaxis detection devices, in particular to a cell chemotaxis detection device. Background technique [0002] A cell chemotaxis device is a cell chemotaxis detection device that detects whether cells move to a well containing a sample sample. [0003] In the structure in which the wells communicating with each other through the flow path are provided with the cell injection port and the sample sample injection port, since the holes form a communication tube through the flow path, it is particularly easy to cause liquid movement in the flow path. That is, when a sample such as a cell is injected into the well, the influence of the pressure increase due to the injection is likely to occur, and thus the unintentional movement of the cell or the sample sample is likely to occur. Moreover, when the level of the well cannot be completely maintained after injection or when the liquid level fluctuates sl...

Problems solved by technology

That is, when a sample such as a cell is injected into the well, the influence of the pressure increase due to the injection is likely to occur, so the cell or the sample sample is likely to move unintentionally.

Moreover, when the level of the well cannot be completely maintained after injection or when the liquid level fluctuates slightly due to vibration, etc., the liquid flow in the channel will also increase, which will easily cause the movement of cells or samples.

[0004] At the same time, the cell chemotaxis device in the prior art cannot satisfy the efficient and stable injection of cells, thus affecting the stability of cell injection
