Abstract

An assembly for the administration of a selected dosage of insulin or other medicaments from a cartridge by moving a plug guided in said cartridge, comprises an adapter assembly for adapting cartridges with different dimensions or contents. The adapter assembly comprises a first threaded element threaded with a thread lead and movable in a moving direction to move the plug, and a second threaded element threaded with a thread lead for setting a selected dosage, pivotably screwed to said first threaded element and limiting the movement of said first threaded element, and wherein said thread lead of said first element and said thread lead of said second threaded element are adapted to the dimensions and/or the contents of said cartridge.

Claims

1. An assembly for the administration of a selected dosage of insulin or other medicaments from a cartridge by moving a plug guided in said cartridge, comprising:

(a) an adapter assembly for adapting cartridges with different dimensions or contents, comprising

(b) a first threaded element threaded with a thread lead and movable in a moving direction to move the plug, and

(c) a second threaded element threaded with a thread lead for setting a selected dosage, pivotably screwed to said first threaded element and limiting the movement of said first threaded element, and wherein

(d) said thread lead of said first element and said thread lead of said second threaded element are adapted to the dimensions and/or the contents of said cartridge.

2. An assembly according to claim 1, and further comprising a rotatable dose setting knob adapted to carry out a rotational movement and means for transferring said rotational movement of said dose setting knob to said second threaded element.

3. An assembly according to claim 2, wherein said dose setting knob is adapted to be locked.

4. An assembly according to claim 2 and further comprising a housing for said dose setting knob and a pressure spring inside said housing, wherein said dose setting knob is adapted to be pressed into said housing against the force of said pressure spring and releasably locked therein.

5. An assembly according to claim 1, wherein

(a) said first threaded element is formed by a threaded rod with an external, male thread,

(b) said adapter assembly comprises a casing having an open side for receiving a cartridge and which is provided with an aperture at its opposite end for guiding said threaded rod in a rotationally secured way, and

(c) said second threaded element is formed by a nut, screwed on said threaded rod from an outside of said casing, the axial position of which being selected by rotation.

6. An assembly according to claim 5, and further comprising securing means for blocking the movement of the threaded rod in an opposite movement direction.

7. An assembly according to claim 6, wherein said securing means are formed by a securing disk attached to said threaded rod with an opening between a front end of said cartridge and an inner front end of said casing and having flexible tongues in the range of said opening engaging with said thread of said threaded rod.

8. An assembly according to claim 1, and further comprising a sensor assembly for contactless sensing the selected and/or administered dosage.

9. An assembly according to claim 8, and further comprising:

(a) magnets on one of the rotating components for adjusting the dosage,

(b) magnetic sensors detecting a rotation of said magnets, and

(c) processing- and display means for processing and/or displaying a dosage corresponding to the detected movement determined from said detected rotation.

10. An adapter assembly for the reception of cartridges having different dimensions and/or contents for an application device for insulin or other medicaments by feed movement of a plug movably guided in said cartridge, comprising:

(a) a first threaded element threaded with a thread lead and movable in a moving direction to move the plug, and

(b) a second threaded element threaded with a thread lead for setting a selected dosage, pivotably screwed to said first threaded element and limiting the movement of said first threaded element, and wherein

(c) said thread lead of said first element and said thread lead of said second threaded element are adapted to the dimensions and/or the contents of said cartridge.

11. An adapter assembly according to claim 10, and wherein

(a) said first threaded element is formed by a threaded rod with an external, male thread,

(b) said adapter assembly comprises a casing having an open side for receiving a cartridge and which is provided with an aperture at its opposite end for guiding said threaded rod in a rotationally secured way, and

(c) said second threaded element is formed by a nut, screwed on said threaded rod from an outside of said casing, the axial position of which being selected by rotation.
