Abstract

The invention discloses an intracellular dialysis apparatus and a dialysis method thereof. The apparatus comprises an electrode dialysis unit and an electrode holder, wherein the electrode dialysis unit is provided with a first micro-cannula and a second micro-cannula, inside of the electrode holder is provided with a central pipe cavity, the electrode holder is provided with a negative-pressure suction side pipe and a micro-cannula sleeve in communication with the central pipe cavity, the first micro-cannula and the second micro-cannula are simultaneously inserted into the micro-cannula sleeve and communicated with the central pipe cavity. According to the invention, beneficial effects are that the intracellular dialysis operation are simple, a liquid changing efficiency is high and a long-term stable observation can be carried out.

Description

Technical field: [0001] The invention belongs to the field of medical equipment, and relates to an electrode liquid replacement device, in particular to an intracellular dialysis device and a dialysis method thereof. Background technique: [0002] Patch clamp technology has become more and more mature and perfect since its creation. Using this technology, people can conduct in-depth analysis of the properties and functions of membrane proteins (such as ion channels and receptors) at the molecular level. But in some experiments, the technique has been limited. For example, when studying the regulation of ion channels by the cell membrane signaling system, it is necessary to apply appropriate drugs in the cells; when analyzing and measuring the current mechanism corresponding to a certain functional state of the cell, it is necessary to use the corresponding electrode fluid according to the measured current. In these cases, strict controls can only be achieved by using a spec...
