Infusion system
First Claim
1. An infusion system for administering a liquid medicinal agent, in particular insulin, comprising:
- a cannula carrier unit comprising an upper side facing away from a body of a patient with a transfer cannula contained within the cannula carrier unit, an under side with an adhesive for directly securing the under side to the body of the patient and the under side is coupled to the transfer cannula, and an infusion cannula for puncturing into the body of the patient, the infusion cannula extending directly from the under side without being outside the perimeter of the under side;
a pump unit removably connected to the upper side of the cannula carrier unit using a positive-fit, the pump unit comprising a pump, a rechargeable battery for supplying energy to the pump, and a medicinal agent container being non-removable from the pump unit carried in a storage volume of the pump unit coupled to the transfer cannula, wherein the pump unit rests on the upper side of the cannula carrier unit after attachment of the pump unit to the cannula carrier unit; and
a charging station configured to receive the pump unit detached from the cannula carrier unit using a positive-fit to both recharge the rechargeable battery and refill the medicinal agent container with the liquid medicinal agent to be administered.

Abstract
Disclosed is an infusion system for administering a liquid medicament, particularly insulin. Said infusion system comprises a cannula support unit which is properly attached to a patient'"'"'s body, an infusion cannula to be inserted into the patient'"'"'s body, and a pump unit that can be connected to the cannula support unit and encompasses a pump, a battery for supplying power to the pump, and a storage volume for the medicament that is to be administered. The pump unit and the cannula support unit are adapted to one another in such a way that the pump unit rests against the cannula support unit once the pump unit has been connected to the cannula support unit. The disclosed infusion system also comprises a charging station for the pump unit in order to recharge the battery of the pump unit.
