摘要

#CMT# #/CMT# The pump has an upper housing part (10), a lower housing part (12) and an arrangement for accommodating a refilling septum (14), a bolus chamber (18) closed by a bolus septum (160 and a capillary (20) and a flexible separating element (26) for dividing a chamber in the lower housing part in a medication chamber and a drive gas chamber. The arrangement is formed in the upper housing part #CMT#USE : #/CMT# For infusing fluids, medication or nutrients into a patient's circulatory system. #CMT#ADVANTAGE : #/CMT# The manufacturing process is simpler and less expensive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional representation of an implantable infusion pump 10 : housing part 12 : lower housing part 14 : refilling septum 16 : bolus septum 18 : bolus chamber 20 : capillary.
