Hemodialysis concentrated liquid supply method and device based on siphon principle

Abstract

The invention discloses a hemodialysis concentrated liquid supply method and device based on a siphon principle. The liquid supply device comprises a drug dispensing system for uniformly mixing medicine liquid, a control component and a liquid supply system, wherein the drug dispensing system comprises a drug dispensing barrel; a first liquid outlet pipe is connected to the drug dispensing barrel; the liquid supply system comprises a first liquid supply barrel and a second liquid supply barrel connected to a second liquid conveying pipe; a third liquid outlet pipe is connected to the bottom of the first liquid supply barrel; a second water pump is arranged on a third liquid outlet pipe; a second tee pipe is connected to the third liquid outlet pipe; a fourth liquid outlet pipe is connected to the water outlet of the second tee pipe; a second liquid feeding electric valve is arranged on the fourth liquid outlet pipe; the location of the bottom surface of the second liquid supply barrel is higher than the location of the top surface of the first liquid supply barrel; a circulating pipeline is connected to the second liquid supply barrel; the outlet end of the circulating pipeline is connected into the first liquid supply barrel; and a plug, which is connected to a hemodialysis machine, is arranged on the circulating pipeline. The liquid supply device and the liquid supply method disclosed by the invention have the beneficial effects that the service life of the water pump is prolonged, and meanwhile, energy consumption is reduced.

AI Technical Summary

Benefits of technology

This patented technology allows two liquids (liquid supplies), one at top and another below them, are kept separate until needed without mixing together or losing their effectiveness due to gravity flow caused by differences between these levels during operation. It also includes various components that help keep this separation while still providing effective fluid delivery capabilities. Overall, this design helps improve efficiency and performance of blood purification machines.

Problems solved by technology

This patented technical problem addressed by this patents relates to an improved blood dialyzer that can be operated more efficiently while reducing its power consumption compared to existing systems due to the use of a separate fluid source (liquid supplying tube).
