ABSTRACT:
Apparatus for administering liquids such as blood or saline solution comprises a readily collapsible but substantially inextensible container with a duct through which liquid can leave the container. Take-up means is provided to restrict the volume of that part of the container communicating with the duct, and referred to as the operative part. The take-up means is adjustable to vary the volume of the operative part. Calibration means is provided to enable the volume or the changes in volume of the operative part to be measured. In one type of construction the duct leads to a junction between a liquid inlet which may be connected to a source of liquid, and a liquid outlet, such as a terminal connector connectable to a needle, a catheter or the like.
