Embodiment Construction

[0046] The drug delivery system of the present disclosure administers a non-user-settable (i.e., fixed or predetermined) dose of a second medicament (i.e., a secondary drug composition) and a first medicament (i.e., a primary drug combination) via a single output or drug dispense interface. substance) in variable doses. The fixed dose of the second medicament is automatically determined by the user setting the dose of the primary medicament. In the example the drug dispensing interface is a needle cannula (hollow needle). figure 1 Generally shown is a multi-dose injection device capable of setting and delivering a dose of a first medicament and a dose of a second medicament via a single dose setter and a single dispense interface. Such injection devices may be modified to include biasing elements (eg, trigger springs) that can assist in delivering the medicament. image 3An exemplary drug delivery device including a trigger spring and capable of assisting in the delivery of ...

Abstract

A drug delivery device having a trigger biasing member (260) providing dispense assistance. The drug delivery device includes a variable dose setting mechanism (202) operatively coupled to a primary reservoir (214) holding a first medicament. The drug delivery device also includes a fixed dose setting mechanism (204) operatively coupled to a secondary reservoir (218) holding a second medicament. The fixed dose setting mechanism includes a trigger biasing element or spring. Additionally, the drug delivery device includes a mechanical linkage (206) operatively coupling the variable dose setting mechanism and the fixed dose setting mechanism. During dose setting, activation of the single dose setter sets a variable dose of the first medicament. Setting a minimum dose of the first medicament results in automatically setting a fixed dose of the second medicament, and during dispensing the trigger spring assists in dispensing at least the fixed dose of the second medicament.

Description

technical field [0001] This patent application relates to medical devices and methods for delivering at least two pharmaceutical agents from separate reservoirs using a device having only a single dose setting mechanism and a single dispense interface. A single dose setting procedure initiated by the user results in delivery to the patient of a non-user-settable dose of the second pharmaceutical agent and a user-variable set dose of the first pharmaceutical agent. The drug delivery device may include a trigger biasing member, preferably a spring, configured to facilitate delivery of the second drug agent. The pharmaceutical agent is contained in two or more dosage reservoirs, containers or packages each containing separate (single drug composition) or premixed (mixed multiple drug composition) drug agent. The disclosed methods and systems are particularly beneficial where target therapeutic responses can be optimized for a particular target patient population through control ...
