Abstract
The application relates to a data collection device for mounting on a rotatable dose setting dial of a medicament administration device. A system comprising the data collection device and the medicament administration device is also provided.
Claims16
A data collection device comprising:
- a distal end, the distal end being open to allow the data collection device to be mounted on a rotatable dose setting dial of a medicament administration device;
- a proximal end, the proximal end being closed;
- a light source configured to project light from the distal end of the data collection device;
- and
- an optical sensor, wherein when the data collection device is mounted on the dose setting dial of the medicament administration device:
- the distal end of the data collection device faces a surface of at least one outward radial protrusion extending beyond an external surface of an external housing of the medicament administration device and the light source is configured to illuminate a portion of the surface of the at least one outward radial protrusion, wherein the at least one outward radial protrusion is located distally with respect to the data collection device and is part of a dial sleeve of the medicament administration device located partially inside the external housing of the medicament administration device and configured to rotate when a dose is dialed;
- and the optical sensor faces the surface of the at least one outward radial protrusion of the dial sleeve and is configured to receive light reflected by at least relatively reflective regions disposed on the surface of the at least one outward radial protrusion of the dial sleeve.

A medicament administration device comprising:
- a housing having a proximal end and a distal end;
- a rotatable dial sleeve located partially inside the housing, the rotatable dial sleeve having a proximal end and a distal end;
- and
- a dose setting dial coupled via a clutch to the proximal end of the dial sleeve, wherein the dial sleeve comprises at least one outward radial protrusion arranged between the proximal end of the housing and a distal end of the dose setting dial and a relatively reflective portion on a proximal surface of the at least one outward radial protrusion of the dial sleeve, wherein the medicament administration device is configured such that the rotatable dial sleeve and the at least one outward radial protrusion are rotationally coupled with the dose setting dial during dose setting and the rotatable dial sleeve and the at least one outward radial protrusion are rotationally decoupled from, and rotate relative to, the dose setting dial during dose delivery.

A system comprising:
- a medicament administration device comprising a housing having a proximal end and a distal end;
- a rotatable dial sleeve located partially inside the housing, the rotatable dial sleeve having a proximal end and a distal end;
- a dose setting dial coupled via a clutch to the proximal end of the dial sleeve, wherein the dial sleeve comprises at least one outward radial protrusion arranged between the proximal end of the housing and the dose setting dial and extending beyond an external surface of an external housing of the medicament administration device;
- and
- a data collection device configured to be mounted on the dose setting dial of the medicament administration device, the data collection device comprising:
- a light source;
- and
- an optical sensor, wherein the light source is configured to illuminate a portion of a surface of the at least one outward radial protrusion of the dial sleeve, and wherein the optical sensor is configured to receive light reflected by at least relatively reflective regions disposed on the surface of the at least one outward radial protrusion of the dial sleeve and incident on the distal end of the data collection device.
