摘要： A fluid infusion system (10) includes a pump (12) having a body (30) that slidable interacts with a handle (32). The body (30) includes a valve housing (44) coupled with an inlet passageway (110), an outlet passageway (123), and a dispensing barrel (48). A finger rest (38) projects from the barrel (48). A loading chamber (58) is recessed within the finger rest (38), and can receive a syringe. A plunger (27), mounted to the handle (32), is received within the barrel (48). The plunger (27) is retracted within the barrel (48) to fill the barrel (48) with fluid. The nozzle (46) of the pump (12) is coupled to a hemostasis valve that is coupled to an infusion catheter (18). The catheter (18) has a distal end (19) with an enlarged tip opening (278) and a plurality of small infusion holes (20) through the side thereof. An annular sensing ridge (276) projects from the interior of the catheter at the opening (278). A wire (22) has an occluding ball (290) at the end thereof to occlude the end (19) of the catheter.
