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 apparatus for administering a fluid drug in doses, comprising:

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; and

an adaptor including a coupling structure for receiving the first housing and the second housing and an attaching structure for extra-corporeally attaching the adaptor to 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 of the patient and at least one of the adaptors is configured to be worn on or carried by article of clothing or an accessory used by the patient.

2. A portable medical apparatus 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 means for controlling the conveying unit;

c) an adaptor comprising coupling means for receiving the first housing together with the reservoir unit and the second housing together with the conveying unit, said adaptor being provided in at least two configurations; and

d) attaching means for extra-corporeally carrying the adaptor on the patient;

wherein

e) the conveying unit and the reservoir unit can be joined together to form a mechanical and fluidic overall unit, without using tools, and coupled to and decoupled from at least two differently embodied adaptors and can thus be joined together with the respective adaptor to form a mechanical and fluidic overall unit, without using tools, and wherein at least one of the adaptors is provided for direct attaching to the surface of the skin and at least one of the other adaptors can be worn on an item of clothing or carried by a wearing system.

3. The portable medical apparatus in accordance with claim 2, wherein the coupling means which enables the conveying unit and the reservoir unit to be mechanically and functionally coupled is substantially formed by the conveying unit and the reservoir unit.

4. The portable medical apparatus in accordance with claim 2, wherein the conveying unit, the reservoir unit and the respective adaptor can be connected to each other via a force-fit or positive-fit connection which can be established without using tools.

5. The portable medical apparatus in accordance with claim 2, wherein the adaptor comprises an adaptor plate for resting on the skin or clothing and a connector for a mechanical and fluidic connection between the reservoir unit and the conveying unit.

6. The portable medical apparatus in accordance with claim 2, wherein the conveying unit and the reservoir unit can be attached to a fluidic-mechanical connector of the respective adaptor and fluidically connected to an outlet of the adaptor.

7. The portable medical apparatus in accordance with claim 2, 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 respective adaptor.

8. The portable medical apparatus in accordance with claim 2, wherein either the conveying unit or the reservoir unit can be joined together with a fluidic-mechanical connector of the adaptor in a force fit or in a positive fit.

9. The portable medical apparatus in accordance with claim 2, wherein one of the adaptor or an adaptor plate associated with the adaptor can be attached to the surface of the skin via one of a releasable adhesive connection or a skin plaster.

10. The portable medical apparatus in accordance with claim 2, wherein one of the adaptor or an adaptor plate of the adaptor comprises means for connecting to a wearing system or an item of clothing.

11. The portable medical apparatus in accordance with the claim 10, wherein the means for connecting comprise means for securing against being unintentionally separated from the wearing system.

12. The portable medical apparatus in accordance with claim 10, wherein the adaptor or adaptor plate is connected to a catheter head which can be disconnected via a catheter line to infuse the drug.

13. The portable medical apparatus in accordance with claim 2, further comprising means for bringing about a secured resting state of the infusion device before separation of the conveying and reservoir units, wherein said means for bringing about is automatically actuated by separation and enables administering automatically after the conveying and reservoir units are joined together.

14. The portable medical apparatus in accordance with claim 2, wherein the conveying unit is for one of a single use or repeated use.

15. The portable medical apparatus in accordance with claim 2, wherein the reservoir unit is for a single use.

16. The portable medical apparatus in accordance with claim 2, wherein at least the adaptor which can be attached to the skin is for a single use.
