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.

Delivery device and method for its operation

Provided is a method for operating a preparation delivery device wherein the device comprises a) a container for the preparation having, or being prepared for the arrangement of, an opening, b) a mechanism operable to deliver at least part of the preparation in the container through the opening, c) attachment means for connection of the container to the mechanism and d) a sensor system arranged to detect at least one predetermined property of the container or its content. The method comprises transmitting radiation towards the container position or a part thereof to allow the radiation to be affected by the container position, receiving at least a part of the affected radiation from at least an area part of the container position in a non-imaging way and comparing the characteristics of the received radiation with a predetermined characteristic representative for the predetermined property to establish whether or not the predetermined property of the container is present.

A preparation delivery device comprising a) a container for the preparation having or being prepared for the arrangement of an opening, b) a mechanism operable to deliver at least part of the preparation in the container through the opening, c) attachment means for connection of the container to the mechanism and d) a sensor system arranged to detect at least one predetermined property of the container or its content. The device comprises a radiation transmitter arranged to irradiate the container position or a part thereof, a radiation receiver arranged to receive at least an area part of the radiation from the transmitter after the radiation having been affected by the container position and the receiver being designed to give an output response representative for the total radiation received from said area part. A method for operating the device comprises the step of transmitting radiation towards the container position or a part thereof to allow the radiation to be affected by the container position, receiving at least a part of the affected radiation from at least an area part of the container position in a non-imaging way and comparing the characteristics of the received radiation with a predetermined characteristic representative for the predetermined property to establish whether or not the predetermined property of the container is present.

An injection device comprising a) a housing, b) a cartridge containing a preparation or precursor components for the preparation and having a front part and a rear part defining a general cartridge axis, an outlet for the preparation arranged at the front part and at least one movable wall arranged between the front part and the rear part, a displacement of which wall causes the preparation to be moved towards or expelled through the outlet, c) a piston rod, having a first end and a second end, at least partly contained within the housing and being operable to engage and displace the movable wall at its first end and d) actuating means within the housing arranged to move at least the rod. According to the invention the device comprises gripping means connected to the housing and arranged to hold the cartridge, or an enclosure therefore, with its front part distal and its rear part proximal to the housing, the actuating means being arranged to move the gripping means so as to move the cartridge, with its rear part leading, relative the housing, locking means able to lock the cartridge against axial movements relative to the housing, hereby defining a locked position for the cartridge, the actuating means being able to move the piston rod between at least one retracted position and at least one extended position, and the relative positions between the piston rod in its retracted position and the cartridge in its locked position being such that the piston rod extends into the cartridge. The invention also relates to a method for operating the device.
