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.

Claims

1. An infusion system for administering a liquid medicinal agent, in particular insulin, comprising:

a cannula carrier unit configured to be secured to a body of a patient and comprises an infusion cannula for puncturing into the body of the patient;

a pump unit attachable to the cannula carrier unit that comprises a pump, a rechargeable battery for supplying energy to the pump, and a storage volume for the medicinal agent to be administered; and

a charging station for the pump unit for charging the rechargeable battery of the pump unit.

2. The infusion system according to claim 1, wherein the storage volume is provided for receiving at least one medicinal agent container.

3. The infusion system according to claim 1, wherein the charging station is set up for filling the storage volume with the medicinal agent to be administered.

4. The infusion system according to claim 1, wherein the pump unit comprises two pump units configured to be charged in the charging station in an alternating manner.

5. The infusion system according to claim 1, wherein the charging station comprises a measuring device for determining an analyte concentration of a sample of body fluid.

6. The infusion system according to claim 1, wherein the charging station and the pump unit comprise means for transmitting data.

7. The infusion system according to claim 1, wherein the pump unit has a pressure sensor for monitoring an infusion pressure of the liquid medicinal agent.

8. The infusion system according to claim 1, wherein the rechargeable battery is incorporated into the pump unit such as to be inaccessible for a user.

9. The infusion system according to claim 1, wherein the charging station is set up to take energy for charging the rechargeable battery of a pump unit coupled to it from an internal energy storing facility.

10. The infusion system according to claim 1, wherein the pump unit has a sensor for monitoring the filling level of the storage volume.

11. The infusion system according to claim 1, wherein the storage volume comprises a refillable bellows bag for storing a liquid medicinal agent, the bellows bag comprises a front end with an opening for passage of the medicinal agent and a back end with a coupling element for positive-fit coupling to a pump rod.

12. The infusion system according to claim 11, further comprising a refillable vial for storing a liquid medicinal agent, the refillable vial comprises a front end with an opening for passage of the medicinal agent and a back end that is closed off by a shiftable plug, wherein a bellows is secured to the plug and protects internal walls of the vial from contamination when the plug is being pushed into the vial.

13. The infusion system according to claim 1, wherein the cannula carrier unit is configured to be secured to the body of a patient, has an infusion cannula for puncturing into the body of the patient and is adapted to a pump unit of the infusion system such that the pump unit rests against the cannula carrier unit after attachment of the pump unit to the cannula carrier unit.

14. An infusion system for administering a liquid medicinal agent, in particular insulin, comprising:

a charging station; and

two pump units, which each comprise a pump and a storage volume for the medicinal agent to be administered configured to be charged in the charging station in an alternating manner.

15. The infusion system according to claim 14, wherein the storage volume comprises a refillable bellows bag for storing a liquid medicinal agent, the bellows bag comprises a front end with an opening for passage of the medicinal agent and a back end with a coupling element for positive-fit coupling to a pump rod.

16. The infusion system according to claim 15, further comprising a refillable vial for storing a liquid medicinal agent, the refillable vial comprises a front end with an opening for passage of the medicinal agent and a back end that is closed off by a shiftable plug, wherein a bellows is secured to the plug and protects internal walls of the vial from contamination when the plug is being pushed into the vial.

17. The infusion system according to claim 14, further comprising a cannula carrier unit whereby the cannula carrier unit, according to its purpose, is secured to the body of a patient, has an infusion cannula for puncturing into the body of the patient and is adapted to a pump unit of the infusion system such that the pump unit rests against the cannula carrier unit after attachment of the pump unit to the cannula carrier unit.

18. The infusion system according to claim 14, the two pump units wherein each pump unit comprises a pump, a rechargeable battery for supplying energy to the pump, and a storage volume for the medicinal agent to be administered and is adapted to a cannula carrier unit of the infusion system such that the pump unit rests against the cannula carrier unit after attachment of the pump unit to the cannula carrier unit.

19. A pump unit for administering a medicinal agent, in particular insulin, comprising a pump and a storage volume for receiving at least two medicinal agent containers.
