Abstract
Liquid flow control devices are described particularly useful for attachment to an infusion administration set including an infusion liquid container connected by a line to an infusion needle, comprising: a conical socket member at one end of the device for connecting same to the infusion container side of the line; a conical pin member at the opposite end of the device for connecting same to the infusion needle side of the line; and fixed-rate liquid metering components including a stem formed with a metering groove and an overlying sleeve, the metering components being located between and communicating with the socket and pin members for metering the liquid flow therebetween according to a preselected fixed rate. The overlying sleeve is resilient and includes a pair of spaced apart protuberances which provide a finger gripping portion and enable the resilient sleeve to be deformed for providing an enlarged flushing passageway for the liquid.
