Cartridge and medical delivery system accommodating such cartridge
First Claim
1. A cartridge that has a medication storing portion and that is suitable for use in a medication delivery device, the cartridge comprising:
- a medicament that is available in a plurality of concentrations and is stored in the medication storing portion of the cartridge;
a mechanical coding selected from a plurality of possible mechanical codings and wherein each of the mechanical codings is indicative of a specific concentration of the medicament and wherein the mechanical coding prevents the cartridge from being accepted by a delivery device that is not designed and calibrated for the concentration of medicament in the cartridge and wherein each of the mechanical codings comprise circular protrusions and wherein the diameter of each protrusion is indicative of a concentration of the medicament.

Abstract
A cartridge having a distal end provided with a mechanical coding. The coding has the form of a circular protrusion where the circular outer diameter is dedicated a specific concentration of insulin contained in the cartridge. The distal end of the cartridge is fitted in to a circular contour in the housing. The outer diameter of the protrusion on the distal end of the cartridge is chosen as a larger diameter for a higher concentration of insulin. In this way only a cartridge containing the correct concentration or a lower concentration fits into a delivery system designed for a specific concentration of insulin.

8. A medication delivery system for delivering medication from a cartridge, the system comprising:
-
a medication delivery device that is calibrated and designed for a specific concentration of a medication and wherein the medication delivery device has a cartridge receiving portion with a shape and diameter so that the medication delivery device accepts only cartridges that use a specific mechanical coding that corresponds to the concentration for which the device is designed and calibrated;
a cartridge containing one of a plurality of different concentrations of medication;
a mechanical coding selected from a plurality of mechanical codings, the mechanical codings corresponding to the different concentrations, wherein the selected mechanical coding corresponds to the concentration that the medication delivery device was designed and calibrated for; and
wherein the selected mechanical coding allows the cartridge to be used only in a delivery device designed and calibrated for the concentration indicated by the selected mechanical coding, wherein the mechanical codings comprise protrusions having different diameter or different length L from a distal surface; and
wherein the selected mechanical coding comprises a continuous circular protrusion extending radially outward from a cylindrical portion of the cartridge and has a diameter with a predetermined value and a predetermined shape that allows it to fit into the cartridge receiving portion of the medication delivery device. - View Dependent Claims (9, 10, 12)

13. A medication cartridge for use with a medication delivery device comprising:
-
a body having a cylindrical wall around a medication storing compartment;
a medication selected from a group of medications suitable for delivery with the medication delivery device and stored in the medication storing compartment; and
a mechanical coding for use with the cartridge;
wherein the mechanical coding comprises a continuous protrusion having a circular cross section covering 360 degrees and extending radially with respect to the cylindrical wall;
wherein the mechanical coding indicative of the specific type of medication in the cartridge, and wherein the mechanical coding allows the cartridge to be used only in medications delivery devices that have been determined in advance to be suitable with the medication in the cartridge. - View Dependent Claims (15, 16, 17, 18, 19, 20)
