Apparatus for automatically delivering hemodialysis solution to a plurality of hemodialysis machines

An apparatus for automatically delivering hemodialysis solution to a plurality of hemodialysis machines, comprising:

• a plurality of supply tanks adapted to be fluidly communicated with a corresponding one of the hemodialysis machines, each of said supply tanks having a bottom portion provided with a connecting port, an upper level sensing unit for detecting whether said supply tan is full, and a lower level sensing unit for detecting whether said supply tank is empty;
• a main tank for containing hemodialysis solution therein, said main tank having an outlet port;
• a solution delivery system including
• a main delivery pipe having an inlet section connected to said outlet port of said main tank,
• an electromagnetic delivery control valve provided on said main delivery pipe,
• a delivery pump provided on said main delivery pipe, and
• a plurality of main branch pipes, each of said main branch pipes having an input portion connected fluidly to said main delivery pipe and an output portion connected fluidly to said connecting port of a respective one of said supply tanks, each of said main branch pipes being provided with an electromagnetic main branch valve, and
• a drain pipe connected fluidly to said main tank and provided with a drain pump and an electromagnetic drain valve;
• and
• a monitoring device connected electrically to said upper and lower level sensing units, said delivery control valve, said delivery pump, said main branch valves, said drain pump and said electromagnetic drain valve, said monitoring device being operable in an automatic mode, wherein said monitoring device activates and deactivates said delivery control valve, said delivery pump and said main branch valves to fill up said supply tanks, and wherein said monitoring device activates and deactivates said drain pump and said electromagnetic drain valve to drain said main tank.
