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.

摘要： A hand operated, fluid dispensing pump (12) includes a body (30) that slidably interacts with a handle (32). The body (30) includes a valve housing (44) fluid coupled with an inlet passageway (110), and outlet passageway (123), and a dispensing barrel (48). A finger rest (156) rigidly projects from the dispensing barrel (48). A loading chamber (58) is recessed within the finger rest (38) and is configured to receive a fluid supply syringe. A plunger (182), mounted to the handle (154), is slidably received within the dispensing barrel (48). As the plunger (182) is advanced within the barrel (48), fluid is dispensed from the pump (12). Once the plunger (182) is fully advanced, a spring (214) disposed between the body (30) and the handle (32) automatically retracts the plunger (182) within the barrel (48). As the plunger (182) is retracted within the barrel (48), the barrel (48) is automatically filled with a fluid from the fluid supply syringe.
