Problems solved by technology

However, despite public relations increasing awareness of the life-saving power of glucagon rescue, this remains largely unknown to the general public
Indeed, studies have shown that parents of children with diabetes have considerable problems with glucagon emergency kits, ranging from difficulty opening the container to drawing the correct dose into the syringe

Embodiment Construction

[0030] The present invention preferably administers a fixed predetermined dose of the second medicament and a variable dose of the first medicament, but necessarily through a single output or drug dispense interface. User setting of the dose of the first medicament is preferably accomplished by a mechanical dose setting and dose delivery mechanism that is completely independent and separate from the dose delivery system used to deliver the second medicament. The only commonality will be the dispense interface in those embodiments where there is no separate dispense interface dedicated to the second drug and the second drug delivery system. A preferred dispense interface is a needle cannula. Acceptable first drug dose delivery mechanisms for use in our invention would include those found on pen type injection devices, in particular those described in published patent application WO2004 / 078239. The '239 application describes the structure and functionality of the drive mechanis...

Abstract

An injection device (7) is disclosed for delivering at least two medicaments, wherein a settable dose of the first medicament is delivered by means of a first medicament dose delivery mechanism (6), and a second medicament delivery system is activated from a micro The reservoir (8) delivers the second drug whereby activation of the second drug delivery system locks the first drug dose delivery mechanism.

Description

technical field [0001] The present invention relates to medical devices and methods for delivering multiple doses of a first medicament and a predetermined user-non-settable dose of a second medicament from a single injection device, preferably a pen-type injection device. The second drug is administered from the microreservoir and may use a single dispense interface shared with the container containing the first drug. Our invention may include electronics and components that control the administration of the second drug, provide visual and verbal indications to the user, and / or may activate a mechanical lock of the first drug dose delivery mechanism to prevent further use of the injection device. Background technique [0002] There are some disease states in which the patient requires frequent administration of medications to keep the disease under control. Typically, the drug is delivered one or more times a day by injection, infusion or inhalation. There is always a ris...
