Abstract

A device to be used with a medical administration device includes administration driver for administrating a prescribed dose of medicament; and a mechanical dose setter for setting a prescribed dose of medicament to be administered, including a mechanical indicating member fixedly connected to the administration driver for indicating the prescribed set dose. The device includes a mechanical dose information device for registering the prescribed dose of medicament to be administered including a mechanical information member adjustable to display that the prescribed dose to be administered is correct and inter-connected to said mechanical indicating member such that when the prescribed dose is set, this is indicated positively by indications on the mechanical information member.

Claims

1. A device to be used with a medical administration device, the device comprising a drive device for administering a prescribed dose of medicament and a mechanical dose setting device for setting a prescribed dose of medicament to be administered, the mechanical dose setting device being rotatable in relation to the drive device, and a mechanical indicating member for indicating the set prescribed dose fixedly connected to the drive device, the device further comprising:

a mechanical dose information member that is movably inter-connected to the mechanical indicating member and that includes a plurality of indications for registering the set prescribed dose such that when the prescribed dose is set is indicated by a positive indication on the dose information member.

2. The device of claim 1, wherein the dose setting device comprises a dose window and a register information window.

3. The device of claim 2, wherein the dose setting device is arranged to be rotated relative to the indicating member during setting of the prescribed dose until the prescribed dose is visible in the dose window, and the dose information member is arranged to be rotated relative to the dose setting device and the indicating member during registration of the prescribed dose until the positive indication is visible in the register information window.

4. The device of claim 3, wherein the dose information member includes a grip-enhancing device for registering the set prescribed dose after setting of the prescribed dose.

5. The device of claim 2, wherein the dose information member comprises a locking device for locking the dose information member to the dose setting device before and during setting and registration of the prescribed dose and for unlocking the dose information member from the dose setting device after setting and registration of the prescribed dose.

6. The device of claim 5, wherein the locking device is switchable and slidable on a surface of the dose setting device for locking the dose information member to the indicating member after setting and registration of the prescribed dose and for unlocking the dose information member from the indicating member before setting and registration of the prescribed dose.

7. The device of claim 6, wherein a ratchet on an inner surface of the dose setting device is arranged to be in contact with at least one pawl on an outer surface of the dose information member when the dose information member is locked to the indicating member and to be out of contact with the at least one pawl when the dose information member is unlocked from the mechanical indicating member.

8. The device of claim 7, wherein the ratchet and the at least one pawl interact to stop counter-clockwise rotation of the dose setting device during setting of the registered dose.

9. The device of claim 2, wherein each of the dose information member and the dose setting device has a protrusion, and the protrusions are arranged to stop clockwise rotation of the dose setting device during setting of the registered dose.

10. The device of claim 2, wherein the indicating member is arranged to rotate, during administration of medicament, from a position in which a correct prescribed dose is visible to a position in which it is indicated that the correct prescribed dose is given, and the dose information member rotates, during administration of medicament, from a position in which it is indicated positively that a correct prescribed dose is set to a position indicating the dose to be set for subsequent dose delivery.

11. The device of claim 1, wherein the dose information member comprises a locking device for locking the dose information member to the dose setting device before and during setting and registration of the prescribed dose and for unlocking the dose information member from the dose setting device after setting and registration of the prescribed dose.

12. The device of claim 11, wherein the locking device is switchable and slidable on a surface of the dose setting device for locking the dose information member to the indicating member after setting and registration of the prescribed dose and for unlocking the dose information member from the indicating member before setting and registration of the prescribed dose.

13. The device of claim 12, wherein a ratchet on an inner surface of the dose setting device is arranged to be in contact with at least one pawl on an outer surface of the dose information member when the dose information member is locked to the indicating member and to be out of contact with the at least one pawl when the dose information member is unlocked from the mechanical indicating member.

14. The device of claim 13, wherein the ratchet and the at least one pawl interact to stop counter-clockwise rotation of the dose setting device during setting of the registered dose.

15. The device of claim 1, wherein each of the dose information member and the dose setting device has a protrusion, and the protrusions are arranged to stop clockwise rotation of the dose setting device during setting of the registered dose.

16. The device of claim 1, wherein the indicating member is arranged to rotate, during administration of medicament, from a position in which a correct prescribed dose is visible to a position in which it is indicated that the correct prescribed dose is given, and the dose information member rotates, during administration of medicament, from a position in which it is indicated positively that a correct prescribed dose is set to a position indicating the dose to be set for subsequent dose delivery.

17. The device of claim 1, wherein the positive indication on the dose information member includes at least one of a dose quantity, an OK indication, a pictogram, an arrow, and a characteristic indication.

18. A device to be used with a medical administration device, the device comprising a drive device for administering a prescribed dose of medicament and a mechanical dose setting device for setting a prescribed dose of medicament to be administered, the mechanical dose setting device being rotatable in relation to the drive device, and a mechanical indicating member for indicating the set prescribed dose fixedly connected to the drive device, the device further comprising:

a mechanical dose information member that is movably inter-connected to the mechanical indicating member and that includes a plurality of indications for registering the set prescribed dose such that when the prescribed dose is set is indicated by a positive indication on the dose information member;

wherein the dose setting device comprises a dose window and a register information window, the dose setting device is arranged to be rotated relative to the indicating member during setting of the prescribed dose until the prescribed dose is visible in the dose window, and the dose information member is arranged to be rotated relative to the dose setting device and the indicating member during registration of the prescribed dose until the positive indication is visible in the register information window.

19. The device of claim 18, wherein the dose information member includes a grip-enhancing device for registering the set prescribed dose after setting of the prescribed dose.
