LABORATORY INFUSION SOLUTIONS IN POLYMER CONTAINERS Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: installation has functional units having maintenance means. It has the laboratory unit proper and storage unit. The proper laboratory unit is divided into two compartments. Frontal compartment serves as auxiliary compartment and the back one serves as assistant aseptic compartment. The proper laboratory unit as a whole comprises functional equipment and maintenance means. An auxiliary compartment of the proper laboratory unit has treated water collector, injection water collector, plant for producing injection water from natural spring water under field conditions, drying box, compressor system, bactericide irradiator, vapor-type sterilizer, arranged along its perimeter. The plant for producing injection water from natural spring water under field conditions comprises precleaning filter, feeding pump, coarse filter, ultrafiltration means, high pressure pump, reverse-osmosis filter, specific electric resistance measurement means, carbon filter, cation-exchange filter, anion-exchange filter, the second specific electric resistance measurement means and cartridge filter for sterilizing by filtering. The reverse-osmosis filter is additionally attached to discharge line. The anion-exchange filter has additional outlet to the treated water collector. The cartridge filter for sterilizing by filtering has additional outlet to the injection water collector. The installation has treated water recirculation option. Complex for producing infusion solutions is mounted in assistant aseptic proper laboratory unit in polymer containers. It comprises system for preparing solution and its sterilizing filtration, aseptic dosing system for filling sterile polymer containers provided with filling needles, and power support unit, unit for controlling infusion solutions quality. The complex for producing infusion solutions in polymer containers has reactor, peristaltic pump, solution filter holder having membrane, connection tube set, dosing and filling device having sphincter valve, air filter holder and micro-box, power supply source, compressor unit. Means for maintaining both units have electrical equipment, illumination, heating and forced ventilation, water supply, internal and external communication systems. Water which quality is not to be higher than that of natural springs is useable in production process raw material.

EFFECT: simplified design.
