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.

Cartridge and medical delivery system accommodating such cartridge

A needle assembly comprises an injection needle and a needle hub, mountable on a syringe, for securing the injection needle. The needle has an injection part extending axially from the hub and terminating in a skin piercing obliquely cut end. The length of the injection part is between 4 and 6 mm, thereby facilitating a proper subcutaneous injection. Also, preferably either (a) the outer diameter of the needle is smaller than 0.320 mm and the bore diameter is larger than 0.165 mm, or (b) the outer diameter is smaller than 0.298 mm and the bore diameter is larger than 0.133 mm. Also, preferably the hub includes an axially extending protrusion, from which the injection part extends, to facilitate insertion of the injection part into the skin of a user at an oblique angle.

Injection needle

The present invention relates to a needle mounted in a needle hub fitting onto an injection device from which preset doses of a medicine from a cartridge accommodated in the device is administered through the needle comprises a back needle penetrating a closure membrane of the cartridge and a free injection part shorter than 9 mm, the outer diameter of the needle and the diameter of its bore complying with one of the conditions: a) the outer diameter is smaller than 0.320 mm and the diameter of the bore is larger than 0.165 mm, or b) the outer diameter is smaller than 0.298 mm and the diameter of the bore is larger than 0.133 mm.

A dispenser for dispensing a dosage or a powdery or fluid drug from a cartridge having a tubular chamber the ends of which are sealed by breakable membranes. The dispenser comprises a housing forming a cylinder which is at one end closed by an end wall through which an outlet pipe communicates with the interior of the cylinder. The other end of the cylinder is closed by a plunger which may be displaced into the cylinder. The drug cartridge is placed in a piston mounted axially displaceable in the cylinder between the end wall and the plunger, and the tubular chamber extends from one side of the piston to the other. Penetrators for breaking the membranes are provided at the inner end of the outlet pipe and the inner end of the plunger.

Disposable dispenser for powder

Tablet dispenser

A pen shaped device for nasal administration of doses of a liquid medicine, comprising a first and a second housing element, the first housing element (1) comprising a cartridge for the medicine, this cartridge being at one end closed by a piston (21) and being at its other end closed by a valve (7,9), which may be opened to connect the cartridge to a spray nozzle (12). When the two housing elements are rotated relatively to each other, a nut member (27) is proportional to the rotation moved along a threaded piston rod (22) to compress a helical spring (32) to act via the nut element (27) and the piston rod (22) on the piston (21) to put the content of the cartridge under pressure, which pressure may be released by opening the valve (7,9) to lead the medicine in the cartridge to the nozzle (12).
