Medicament dispensing device
First Claim
1. A medicine injection device equipped with a formulation syringe which is previously containing a formulation and used to inject the formulation into a living body, the medicine injection device comprising:
- a syringe detecting switch configured to detect replacement of the formulation syringe;
an injection needle detecting section configured to detect an attachment of an injection needle to the formulation syringe;
a microprocessor configured to check whether the formulation syringe is replaced during a time from the precedent attachment of the injection needle to the current attachment of the injection needle when the injection needle detecting section detects the attachment of the injection needle to the formulation syringe;
a timer configured to start counting a use time of the formulation syringe when the microprocessor confirmed the formulation syringe is replaced during a time from the precedent attachment of the injection needle to the current attachment of the injection needle;
a storage section which stores data of a predetermined term of expiration of the formulation from a start of use;
the microprocessor configured to check whether the use time exceeds the term of expiration of the formulation from the start of use; and
a notification section configured to notify warning that the term of expiration of the formulation from the start of use is over when the use time exceeds the term of expiration of the formulation from the start of use.

Abstract
A medicament dispensing device capable of managing the effective use period of a medicament preparation-containing syringe by simply and accurately detecting a period of time after the start of use of the preparation. In a medicament dispensing device (1), when a medicament preparation-containing syringe (11) is replaced, a microprocessor (23) detects the time at which the replacement is performed as the time of the start of use of the preparation, and counts the elapsed time after the use of the preparation has started. Then, the microprocessor (23) notifies the result of the counting by a LCD (10), etc. to the user. Also, the microprocessor (23) detects that a syringe needle for dispensing the preparation has been mounted, and after detecting the mounting of the syringe needle, the microprocessor (23) counts the elapsed time after the start of use of the preparation. In a step S12, the microprocessor (23) checks whether or not the elapsed time counted by a timer (21) has exceeded a specified time. When an effective use period has expired, the microprocessor (23) issues a message in a step S17 that the effective period of a medicament has expired.
