Abstract

A portable medical apparatus for administering a fluid drug in doses, including a first housing including a reservoir unit with an outlet into a fluid path for conducting the drug, a second housing including a conveying unit for dispensing the drug from the reservoir unit in doses and a suitable controller for controlling the conveying unit, an adaptor including a coupling structure for receiving the first housing and the second housing and an attaching structure for extra-corporeally carrying the adaptor on a patient, wherein the conveying unit and the reservoir unit can be joined together to form an integrated mechanical and fluidic unit, and coupled to and decoupled from at least two differently configured adaptors, wherein at least one of the adaptors is configured to be directly attached to the surface of the skin and at least one of the adaptors is configured to be worn on or carried by an article of clothing or a wearing system (e.g., a belt).

Claims

1. A portable medical system for administering a fluid drug in doses, comprising:

a) a first housing comprising a reservoir unit including an outlet into a fluid path located downstream of the reservoir unit for conducting the drug;

b) a second housing comprising a conveying unit for dispensing the drug from the reservoir unit in doses and a controller for controlling the conveying unit;

c) at least two differently configured adaptors receiving the first housing together with the reservoir unit and the second housing together with the conveying unit wherein

d) the conveying unit and the reservoir unit can be joined together without using tools, and reversibly coupled to each of the adaptors without using the tools, and wherein at least one of the adaptors is provided for direct attachment to a skin surface and at least one of the other adaptors can be worn on an item of clothing or carried by a wearing system; and

e) wherein the adaptors each has a pair of mechanical connectors which receive and engage releasably in opposition the first housing and the second housing.

2. The portable medical system of claim 1 wherein mechanical and functional coupling of the conveying unit and the reservoir unit is via a coupling means formed by the conveying unit and the reservoir unit.

3. The portable medical system of claim 1 wherein the conveying unit, the reservoir unit and the at least one of the adaptors can be connected to each other via a force-fit or positive-fit connection which can be established without using the tools.

4. The portable medical system of claim 1 wherein the conveying unit and the reservoir unit can be fluidically connected to an outlet of the at least one of the adaptors.

5. The portable medical system of claim 1 wherein the conveying unit and the reservoir unit can be joined together in a positive fit or in a force fit on a fluidic-mechanical connector of the at least one of the adaptors.

6. The portable medical system of claim 1 wherein the conveying unit and the reservoir unit can be joined together in a force fit or in a positive fit.

7. The portable medical system of claim 1 wherein the at least one of the adaptors that is provided for direct attachment to a skin surface comprises a releasable adhesive connection or a skin plaster to couple the portable medical apparatus to the skin surface.

8. The portable medical system claim 1 wherein the at least one of the other adaptors that can be worn on the item of clothing or carried by the wearing system comprises a pendant strap, a belt strap encircling a body, a belt clip or a way of being attached to the item of clothing for connecting to the wearing system.

9. The portable medical system of claim 1 wherein the coupling structure is configured to prevent unintentional separation of the reservoir unit and the conveying unit.

10. The portable medical system of claim 9 wherein the coupling structure is configured such that two different manipulations is required to separate the reservoir unit and the conveying unit.

11. The portable medical system of claim 1 further comprising a catheter head which can be disconnected via a catheter line to the portable medical apparatus to infuse the drug.

12. The portable medical system of claim 1 wherein the conveying unit is for one of a single use or repeated use.

13. The portable medical system of claim 1 wherein the reservoir unit is for a single use.

14. The portable medical system claim 1 wherein the at least one of the adapter which can be attached to the skin surface is for a single use.

15. The portable medical system of claim 1 wherein the wearing system is configured to encircle a body of the patient.
