Problems solved by technology

The switch based sensing system described in US Pat. No. 4,838,857, which is opened by the container when in position, would be extremely inflexible without arranging many switches, and the system would be susceptible to wear and contamination
The interlocking based mating structure described in EP549694 is inflexible, imprecise and easily cheatable, and is incompatible with the special wedge-shaped features provided on the cartridge and standard containers
Known methods are too specialized, easy to forge, and unsuitable for reading supplementary information

Embodiment Construction

[0091] 1a and 1b schematically show a cylindrical container 1 having a cylindrical part 2 and containing a piston 3 with three sealing rings 4 . Attached to the cylindrical part 2 is a label 5, assumed to be a barcode surface on a fully reflective backing. The emitter 6 emits radiation in the form of a large cone 7 . Arranged next to the emitter 6 and facing the same side, the first receiver 8 receives radiation from a cone 9 slightly smaller than the emitter cone 7 . The second receiver 10 is arranged on the other side of the container with respect to the transmitter 6 , facing the transmitter 6 . The third receiver 11 is at about 90 degrees relative to the axis of the transmitter 6 and faces the inside of the container. In the relative position shown, the radiation of the transmitter 6 is directed at the tag 5 and the first receiver 8 receives the radiation radiated by the transmitter 6 and reflected from the tag. When the label is not translucent, the receivers 10 and 11...

Abstract

A system of marked medical containers comprises at least two containers having different properties in at least one respect, and at least one machine-readable marking on each of the containers, each marking being designed to allow discrimination between the difference in properties. Each marking allows discrimination between the difference by having at least one area with different absorbence or reflectance when irradiated with radiation in non-visible frequency ranges. A specific container comprises a syringe cartridge type container for use with a preparation delivery device.

Description

technical field [0001] The present invention relates to a formulation delivery device comprising a) a formulation container having an opening or a structure prepared for opening, b) a mechanism capable of delivering at least part of the formulation in the container through the opening, c) a coupling means connecting the container and the mechanism, d ) A sensor system for detecting at least one predetermined property of a container or a substance contained within a container. The invention also relates to a method of operating such a device, to a container or container system for use with the delivery device, and to a marking system or analysis device for the components of the delivery device. Background technique [0002] Due to the flexibility and economy of being able to provide reusable pump devices with more or less advanced mechanisms for preparation, dosing, and control and monitoring of the injection process, separation based on interchangeable container coupling Sy...
