Abstract
A dose display for a medicine administration device in which rotation of a dose setting actuator (22) is transmitted to a display means comprises a flexible disc (23) carrying numbers in a band along its perimeter, which numbers are in accordance with the set dose presented in a window in a wall of the device to show said dose. During its rotation the disc (23) is deflected to follow an inner contour of the device to attain a cylindrical shape having a generatrix extending in the axial direction of the injection device and perpendicular to the axis of rotation of the disc.
Claims13
A medical device having a dosage display, the medical device comprising:
- a housing having:
- a longitudinal dimension, a window, and an inner contour having a surface shaped to deflect a flexible disc in a generally cylindrical manner,
- a dose setting actuator,
- a display means carrying digits that, in accordance with the set dose, are shown in the window, wherein:
- the display means comprises at least one rotatable flexible disc that is driven by the dose setting actuator and carries numbers along its perimeter that can, depending on the rotational position of the disc, be presented in the window to show a set dose, the disc being deflected to follow the inner contour of the housing to attain a cylindrical shape having a generatrix extending in the longitudinal direction of the injection device and perpendicular to the axis of rotation of the disc.
A medical device with a dosage display, the device comprising:
- a housing having a window and an inner surface with a contour,
- a dose setting mechanism having a dose setting member to set a dose, and
- a display means having numbers, wherein:
- the display means comprises at least one rotatable flexible disc, which is driven by the dose setting mechanism,
- the disc carries digits along an outer perimeter, and
- the disc is deflected to follow the inner contour of the housing to attain a cylindrical shape and displays at least a portion of the numbers in the window, the displayed numbers corresponding to the set dose.
A dosage display comprising:
- a window;
- a flexible rotatable disc carrying numbers along a perimeter;
- a means for deflecting the disc in a generally cylindrical manner;
- and
- a means for rotating the disc to display a number from the disc in the window, the number corresponding at least partially to a set dose.
