DEVICE FOR METERED DRIP INFUSION Russian patent published in 2001 - IPC

FIELD: medical equipment, particularly, disposable system for intravenous infusions. SUBSTANCE: device has flow chamber and discharge pipeline. Chamber accommodates hydrodynamic drip indicator in the form of body with flow-through channel whose one end has inlet communicating directly or through additional hole with chamber cavity, its other ends has outlet made as hydrodynamic seal in the form of hole flow-through under definite pressure with preset minimal hydrostatic working level. In this case, outlet may be made in the form of slit-like or longitudinal hole at channel outlet, and part of discharge pipeline is bent in the form of spiral. EFFECT: simplification of device design with simultaneous increasing of resolving power of registration of minor volumes of fluid and higher accuracy of indication of flow rate of drip infusion. 6 cl, 6 dwg
