APPARATUS FOR DOSING OF INFUSION SOLUTIONS INTO POLYMER CONTAINERS AND WELDING THE SAME Russian patent published in 2004 - IPC

FIELD: equipment for dosing of medicinal preparations and high-frequency welding of polymer materials in medical, pharmaceutical and scientific enterprises and drug stores.

SUBSTANCE: apparatus has casing, solution reservoir, pump, connecting pipe, and control unit connected to electric power source and pump, column, dosing unit including polymer pipe mounted between pump and connecting pipe, electromagnet with movable core, movable pinching member mechanically connected to movable electromagnet core and immovable pinching member fixed on casing, welding unit including high-frequency generator, additional electromagnet with movable core, movable welding electrode mechanically connected to movable core, immovable welding electrode connected to casing, first and second time relays. Apparatus is further provided with container pipe position sensor, third and fourth time relays. Control unit, dosing unit and welding unit are fixed on column. Pipe position sensor is fixed on connecting pipe of dosing unit and is electrically connected to control unit. Pinching members are arranged between pump and connecting pipe. Electromagnet is connected to pipe pinching members and is switched to control unit through third time relay having lag time greater than that of fourth time relay, through which welding unit is connected to control unit.

EFFECT: increased efficiency by automatic dosing of infusion solutions into containers and welding thereof.
