MEDICAL INJECTION DEVICE WITH TIME DELAY INDICATOR

摘要

The present invention relates to an indicating device (100) for use with medical injection devices for administering a drug into the body of a subject user wherein the indicating device is configured for indicating after administration that a dose of the drug actually has been administered and for maintaining this indication until lapse of a pre-defined time interval. The time delay indicator (120) disclosed may be based on a mechanical time delay device and includes a visual indicator that is controlled by the mechanical time delay device for signalling the status of the device during lapse of the pre-defined time interval. The injection device (100) includes a force absorbing structure (110, 111, 130, 140, 150) adapted to absorb activation forces exerted on an activation member (110, 111) and exceeding a pre-defined magnitude from being transferred to the time delay indicator (120).
