Implantable dosaging system
First Claim
1. Implantable dosaging system for medications, active substances, etc., to be administered in the form of dissolved or suspended fluids, comprising:
- a housing defining a medication reservoir, the housing having a self sealing injection port leading into the medication reservoir and a pump located within the housing for pumping a medication from the reservoir out of the housing through a discharge opening and a pump outlet for administering the medication, said pump being transcutaneously operable with the aid of an actuator located on the housing, a one way outlet valve being located at the pump outlet; and
,wherein the pump is a piston plunger pump having a pump chamber coupled to the medication reservoir by an inlet check valve, the outlet valve is a fluid pressure-dependent opening pipe compression valve and the discharge opening can be reversibly supplied with fluid by the operation of the actuator of the pump via the pipe compression valve.

Abstract
An implantable dosaging system for medications, active substances, etc. administered in the form of dissolved or suspended fluids having a medication reservoir, a pump for administering the medication, an actuator for the transcutaneous operation of the pump, a self-sealing port, particularly for refilling the medication reservoir and optionally a dosaging line leading from the pump to the administration point of the medication. Preferably there is a housing (2) and a separate medication reservoir (9), in which the pump is located within the housing (2) and the administration of the medication takes place with the aid of a discharge opening provided in the housing (2), the actuator (5) and the self-sealing port (6) are provided on the housing (2), a connecting line (8) is provided between the housing (2) and the medication reservoir (9) and optionally the dosaging line (7) leads from the discharge opening to the administration point of the medication.
