Embodiment Construction

[0078] In the present invention, a fixed predetermined dose of a second drug compound (secondary drug) and a variable dose of either the primary or first drug compound (primary drug) may be administered through a single output or drug dispense interface. The dose of the primary drug set by the user automatically determines the fixed dose of the secondary drug, which is preferably a single dose contained in a sachet or reservoir with an integral flow dispenser. In a preferred embodiment, the drug dispense interface is a needle cannula (hollow needle). figure 1 Dosing Module 4 is shown (see Figure 2-4 ) can be connected to an example of a drug delivery device 7 (see Figure 2-4 ). The medicated module 4 is connectable to connection means 9 on the cartridge holder 50 at the distal end 132 of the device 7 . Each medicated module 4 is preferably independent and is arranged as a sealed and sterilized disposable module with connection means 8 (see Figure 4 ), which is compatibl...

Abstract

A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module (4) also contains a needle guard (42) that locks after dose delivery. The needle guard (42) prevents accidental needle sticks before and after an injection. A locking collar (66) rotates during use as an inner protrusion (12) follows three paths (14, 15, 16) of a track (13) located on the outer surface of a body housing (10). When the inner facing protrusion (12) is in the third path (16), it encounters a hard stop and a rotational bias that locks the guard (42) from further retraction and thus covers the sharp distal end of the needle (3).

Description

technical field [0001] Particular embodiments of the present invention relate to methods and medical devices for delivering at least two medicaments from separate reservoirs using a device having only a single dose setting mechanism and a single dispense interface. A single delivery program initiated by the user may result in a non-user-settable dose of the second or secondary drug and a variable set dose of the first or primary drug to be delivered to the patient. The medicament may fit into two or more reservoirs, containers or packs, each containing individual (single drug compound) or premixed (multiple drug compounds formulated in combination) medicament. In particular, the present invention relates to a medicated module in which the user must choose whether to dispense a second medicament or to bypass the second medicament and dispense only the first medicament. The present invention is particularly beneficial in that by controlling and defining the treatment situation ...
