Problems solved by technology

[0009] Resetting of known dose setting mechanisms has some significant disadvantages
One obvious disadvantage is that the pen-type device user must disassemble the device to remove the empty cartridge or reset the device in some way
As such, another significant disadvantage is that such devices have a large number of parts and are therefore often complex from a manufacturing and assembly point of view
For example, some typical resettable pen-type devices are not intuitive as to how the user must replace an empty cartridge or how the user resets the device.
Furthermore, due to the large number of component parts used in such resettable devices, such resettable devices tend to be large and bulky, and thus not easily portable or concealable

Abstract

A dose setting mechanism for a drug delivery device is disclosed. The mechanism comprises an outer housing and an inner housing having an external groove and a helical spline. The inner housing helical spline guides a driver to dispense a set dose. A dial sleeve is disposed between the outer and inner housing and is rotatably engaged with the inner housing. When a dose is set, the dial sleeve is rotated and translates away from both the outer housing and the inner housing.

Description

[0001] This application is a divisional application of an application with an international filing date of May 28, 2010, an application number of 201080033685.X, and an application titled "Drug Delivery Device Inner Shell with Helical Splines". technical field [0002] The present application is generally directed to dose setting mechanisms for drug delivery devices. More specifically, the present application is generally directed to a dose setting mechanism for a drug delivery device comprising an inner housing with helical splines. Aspects of the invention are equally applicable to other situations as well. Background technique [0003] Pen-style drug delivery devices can be used for regular injections by people without formal medical training. This is increasingly common among diabetics, where self-treatment allows such patients to manage their disease effectively. [0004] There are basically two types of pen delivery devices: resettable (ie, reusable) and non-resettab...
