Fluid flow control assembly

摘要

A flow control assembly, particularly for intravenous usage, is comprised of a fluid receiving member having a fluid channel and a fluid conduit in fluid flow communication with a source of intravenous fluid; a fluid dispensing member preferably including a drip chamber for connecting a conduit thereto; and fluid flow control member positioned between the fluid receiving member and the fluid dispensing member and having a plurality of flow channels of predetermined cross-section thereby forming with the fluid dispensing member calibrated flow passageways to the drip chamber whereby rotation of the fluid dispensing member with respect to the fluid receiving member selectively orients the fluid channel of the fluid receiving member to one of the calibrated flow passageways thereby to establish a predetermined fluid flow rate from the source of the intravenous fluid to the recipient thereof.
