Abstract
An infusor (10) is disclosed for dispensing a liquid under pressure at a predetermined flow rate. The influsor (10) includes a housing (12) containing an elastomeric bladder (16) for receiving the liquid under pressure. The liquid is delivered from the bladder to a patient through tubing (36). A non-adjustable, preselected flow regulator (38) includes a capillary bore (48). The flow regulator (38) is disposed at the distal end of the tubing (36), such that the tubing may be primed quickly, in a time period virtually unaffected by the flow regulator (38). Distal placement of the flow regulator (38) results in a more constant temperature, and thus a more constant flow rate, of fluid flowing through the flow regulator.
