Medicament injection apparatus

摘要

The present invention relates to a medicament injection apparatus that permits injection of a fluid medicament into a patient through a needle. If the needle is withdrawn before the injected medicament has properly dispersed locally from the injection site within a patient, the injected medicament may escape through the needle wound and not be dispersed into the patient. Unfortunately, it is common for a user to become impatient and withdraw the needle when the user feels a suitable dispersal period has elapsed. Often the waiting period determined by the user is less than the required period for dispersal of the medicament resulting in the problem identified. A medicament injection apparatus is disclosed comprising a timer and a display, the timer being actuated upon commencement of an injection operation, in which the timer runs to a predetermined time subsequent to completion of the injection operation and the display is operated while the timer runs.
