U-shaped tube rapid drug delivery system and control method

Abstract

The invention discloses a U-shaped tube rapid drug delivery system which comprises a U-shaped tube, a drug delivery device, a tube clamping device and a negative pressure device, the drug delivery device comprises a plurality of drug delivery tubes, a plurality of infusion tubes are connected between the drug delivery tubes and the U-shaped tube, and the tube clamping device comprises a plurality of tube clamping valves corresponding to the drug delivery tubes to control connection and disconnection of the plurality of infusion tubes respectively. The negative pressure device is connected with the U-shaped pipe through a pipeline, so that the U-shaped pipe is filled with medicine in the medicine feeding pipe under the action of the negative pressure device, the bent bottom surface of the U-shaped pipe is provided with a liquid outlet hole, the outlet end of the U-shaped pipe is provided with a negative pressure valve, and when the negative pressure valve is closed, the medicine in the U-shaped pipe is sprayed to a culture dish. When the negative pressure valve is opened, the cleaning liquid in the medicine feeding pipe flushes the U-shaped pipe under the action of the negative pressure device. According to the invention, the work of rapid administration, cleaning and dressing change is realized, the experiment time is effectively saved, and the experiment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a U-shaped tube rapid drug delivery system and a control method. Background technique [0002] In the patch clamp cell recording system, it includes a petri dish placed on the experimental operation table. The petri dish is a place to maintain the long-term survival of living cells and control the exchange of extracellular fluid. This exchange is provided by the dosing device to The living cells or slices in the culture dish are injected with oxygen-saturated extracellular fluid that meets different requirements, or injected with extracellular fluid mixed with drug components of different solubility. For the patch clamp experiment, since the patch clamp experiment needs to inject extracellular fluid with different drug components, it is necessary to clean the dosing device when changing the liquid during each experiment, but the existing liquid changing effect is genera...

[0002] In the patch clamp cell recording system, it includes a petri dish placed on the experimental operation table. The petri dish is a place to maintain the long-term survival of living cells and control the exchange of extracellular fluid. This exchange is provided by the dosing device to The living cells or slices in the culture dish are injected with oxygen-saturated extracellular fluid that meets different requirements, or injected with extracellular fluid mixed with drug components of different solubility. For the patch clamp experiment, since the patch clamp experiment needs to inject extracellular fluid with different drug components, it is necessary to clean the dosing device when changing the liquid during each experiment, but the existing liquid changing effect is general and cannot be achieved. Rapid liquid change and cleaning, thus greatly increasing the experimental time and efficiency
