Problems solved by technology

[0017] Delivery of one or more drugs through a dose dispenser with a dispense interface may result in contamination of the dispense interface with traces of each drug
This contamination may prevent re-use of the dispense interface, e.g. after a certain time or after a predetermined number of uses, since the purity of the drug delivered cannot be guaranteed
Even consumers who are aware of the problem may inadvertently attempt to reuse an allocation interface because they don't remember or it is difficult or impossible to check to see if a given allocation interface has actually been used

Embodiment Construction

[0086] figure 1 The drug delivery device shown includes a body 14 extending from a proximal end 16 to a distal end 15. At the distal end 15, a removable end cap or cover 18 is provided. The end cap 18 and the distal end 15 of the main body 14 work together to provide a snap fit or form-fitting connection so that once the cover 18 is slid onto the distal end 15 of the main body 14, the frictional fit between the cap and the outer surface 20 of the main body Prevent the cover from accidentally falling from the main body.

[0087] The main body 14 houses a microprocessor control unit, an electromechanical transmission system, and at least two drug reservoirs. When the end cap or cover 18 is removed from the device 10 (e.g. figure 1 (Shown), the dispense interface 200 is mounted to the distal end 15 of the main body 14, and a dose dispenser (for example, a needle assembly) is attached to the interface. The drug delivery device 10 can be used to administer the calculated dose of the...

Abstract

The invention is related to an apparatus comprising a dispense interface for use with a drug delivery device, the dispense interface comprising a lockout element being arranged at least partially between an outer body of the dispense interface and an inner body of the dispense interface and wherein the lockout element is configured to be removeably maintained in a first position, such that when the dispense interface is first attached and then removed from said drug delivery device, the lockout element moves into a second position, wherein the lockout element in the second position is configured to prevent said dispense interface from being reattached to a drug delivery device.

Description

Technical field [0001] This patent application relates to a medical device for delivering at least two medicaments from separate reservoirs. Such agents may include first and second drugs. The medical device includes a dose setting mechanism for automatic delivery or manual delivery of the medicament by the user. In particular, the invention relates to a dispense interface including a locking element for such medical devices. [0002] The medical device may be a syringe, such as a hand-held syringe, in particular a pen-type syringe, which is a type of syringe that achieves administration by injecting a medical product from one or more multi-dose cartridges. In particular, the present invention relates to such a syringe in which the user can set a dose. Background technique [0003] The medicament can be contained in two or more multi-dose reservoirs, containers, or packs, each of which contains an independent (single drug compound) or premixed (co-formulated multiple drug compou...
