  • Patent number: 10953163
    Abstract: 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. 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.

  • Patent number: 10729851
    Abstract: With certain implementations, the configuration is such that a controller uses a first driver to move a pharmaceutical syringe attachment component closer to the distal end side than a needle removal position when a needle unit is attached to a pharmaceutical syringe unit or when the needle unit is removed from the pharmaceutical syringe unit, so when an injection needle is attached to the pharmaceutical syringe unit, or when the injection needle is removed from the pharmaceutical syringe unit, these operations can be executed without removing a distal end cap, which makes the device extremely convenient to use.
