Claims19
An implantable infusion pump for infusing medication into a patient, the pump comprising a reservoir for containing the medication and an injection access port into the reservoir, the reservoir being acted upon by a pumping mechanism;
- and
- an openable and closable shield at the access port blocking access of an injection needle into the port and into the reservoir when closed and allowing access of the injection needle into the port and into the reservoir when open.
A method for restricting access to a drug reservoir in an implanted infusion pump wherein the drug reservoir is accessible through an access port and the reservoir being acted upon by a pumping mechanism, the method comprising the steps of:
- shielding the access port and the reservoir with a shield during a time when access to the reservoir is not to be allowed;
- and
- moving the shield to allow access to the port and the reservoir during a time when access to the reservoir is to be allowed.
