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 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 on a wearing system wherein the at least two differently configured adaptors each releasably couple to the conveying unit and the reservoir at the same coupling points as each other,

one of the at least two differently configured adaptors comprising a first adaptor plate for directly attaching to the skin of the patient and an injection needle projecting from the first adaptor plate, and the other of the two differently configured adaptors comprising a second adaptor plate with a lateral cannula connector or catheter supply line.

2. The apparatus of claim 1 further comprising a means for bring about a secured resting state of the portable medical apparatus.

3. 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 a controller for controlling the conveying unit;

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

d) an attachment for extra-corporeally carrying the adaptor on the patient;

wherein

e) the conveying unit and the reservoir unit can be joined together 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 without using tools, and wherein at least 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;

(f) wherein the portable medical apparatus further comprises means for bringing about a secured resting state of the portable medical apparatus before separation of the conveying and reservoir units, wherein the means for bringing about the secured resting state is automatically actuated by separation and enables administering automatically after the conveying and reservoir units are joined together; and

(g) wherein the at least two differently embodied adaptors each releasably couple to the conveying unit and the reservoir unit at the same coupling points as each other, one of the two differently embodied adaptors comprising a mechanical coupling structure, a septum, and a cannula, while the other of the two differently embodied adaptors comprises the mechanical coupling structure, the septum, and a supply line, the injection needle and the supply line each exiting the bottom of an adaptor plate.

4. The portable medical apparatus of claim 3 wherein the 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.

5. The portable medical apparatus of claim 3 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.

6. The portable medical apparatus of claim 3 wherein at least one of the adaptor plates is configured for resting on the skin or the clothing and comprises a connector for a mechanical and fluidic connection between the reservoir unit and the conveying unit.

7. The portable medical apparatus of claim 3 wherein the conveying unit and the reservoir unit can be fluidically connected to an outlet of the adaptor.

8. The portable medical apparatus of claim 3 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.

9. The portable medical apparatus of claim 3 wherein either the conveying unit or the reservoir unit can be joined together in a force fit or in a positive fit.

10. The portable medical apparatus of claim 3 further comprising a releasable adhesive connection or a skin plaster to couple the portable medical apparatus to the surface of the skin.

11. The portable medical apparatus of claim 3 further comprising a pendant strap, a belt strap encircling the body, a belt clip or a way of being attached to the item of clothing for connecting to the wearing system.

12. The portable medical apparatus of claim 3 further comprising a means for securing against being unintentional separation from the wearing system.

13. The portable medical apparatus of claim 3 further comprising a catheter head which can be disconnected via a catheter line to the portable medical apparatus to infuse the drug.

14. The portable medical apparatus of claim 3 wherein the conveying unit is for one of a single use or repeated use.

15. The portable medical apparatus of claim 3 wherein the reservoir unit is for a single use.

16. The portable medical apparatus of claim 3 wherein at least the adaptor which can be attached to the skin is for a single use.

17. The portable medical apparatus of claim 3 wherein the means for bringing about the secured resting state comprises an electronic means wherein the electronic means comprises electrical components, computer components, electronic components, circuitry, wires, wireless components, chips, boards, microprocessors, inputs, outputs, displays, control components, and combinations thereof.

18. The portable medical apparatus of claim 3 wherein the wearing system is configured to encircle a body of the patient.
