Abstract

The present invention provides an infusor including a housing, a reservoir accommodated in the housing for containing a product fluid to be administered, and a delivery means accommodated in the housing for an automatic dosed delivery of the product fluid from the reservoir, wherein the reservoir includes at least two separate fluid spaces having separate fluid outlets.

Claims

1. An infusor comprising:

a housing;

a reservoir accommodated in said housing for containing a product fluid to be administered, said reservoir having at least two separate fluid spaces each space having a separate fluid outlet, wherein each reservoir includes a separately actuable piston;

automated delivery means disposed within the housing and coupled with each actuable piston for an automatic, dosed delivery of said product fluid from said reservoir; and

a programmable controller coupled with the automated delivery means to cause the delivery means to deliver the product fluid from the reservoir.

2. The infusor as set forth in claim 1, wherein said product fluid is deliverable optionally from said fluid spaces.

3. The infusor as set forth in claim 1, wherein, for separate conductance of said product fluid delivered form said respective fluid space, at least one separate fluid conduit is provided for each of said fluid spaces.

4. The infusor as set forth in claim 3 wherein said separate fluid conduits form an integral, multilumen catheter body.

5. The infusor as set forth in claim 3, wherein said separate fluid conduits are separate passage conduits at least up to a catheter head carrying at least one piercing needle.

6. The infusor as set forth in claim 5, wherein said catheter head encloses a fluid guide means connecting said separate fluid conduits to said at least one piercing needle.

7. The infusor as set forth in claim 5, wherein said catheter head encloses a fluid guide means connected at an outlet end with said at least one piercing needle, and comprises at least two fluid inlets fo which at least one is closed by a septum which after being punctured by a needle, seals the needle at the puncture site.

8. The infusor as set forth in claim 1 wherein in one of said at least two fluid spaces of said infusor, product fluid of a first type is contained, and in the other of said at least two fluid spaces, product fluid of another type is contained.

9. The infusor as set forth in claim 1 wherein an adapter is connectable to said housing into which said separate fluid conduits port and in which fluid connections are configured, each of which connects one of said separate fluid spaces of said infusor to one of said separate fluid conduits.

10. The infusor as set forth in claim 9, wherein said fluid connections are configured in at least one cap releasably connected to said adapter.

11. The infusor as set forth in claim 10, wherein a fluid connection is formed by a connecting needle embedded in and protruding from said cap such that it protrudes into one off said separate fluid spaces of said infusor when said cap is secured in place.

12. The infusor as set form in claim 10, wherein a sealing element is arranged at a connecting location on said cap connecting one of said separate fluid conduits at which said fluid connection of said cap ports into a cap surface.
