Cartridge And Medical Delivery System Accommodating Such Cartridge
First Claim
1. A medication delivery system for delivering medication from a cartridge, the medication delivery 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, or a lower concentration;
a cartridge containing one of a plurality of different concentrations of medication, the cartridge containing at least one mechanical coding selected from a plurality of mechanical codings, the mechanical coding(s) comprising at least one circular element(s) shaped as substantially continuous circumferential protrusion having a circular cross section when viewed in an axial cross section of the cartridge and extending radially outward from a cylindrical portion of the cartridge and having 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 and wherein the cartridge is structured to be axially insertble into a medical delivery device in any rotational orientation; and
wherein the selected mechanical coding(s) allow(s) the cartridge to be used only in a delivery device designed and calibrated for the concentration indicated by the selected mechanical coding(s), or a lower concentration, wherein the mechanical coding(s) comprise protrusion(s) having different diameter(s) and/or different length L from a distal surface.

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.
