Method for controlling pharmaceutical injection device

Abstract

Certain embodiments of the present invention relate to a pharmaceutical injection device, and it is an object thereof to optimize the mixing of pharmaceutical in a pharmaceutical cartridge. To achieve this object, a pharmaceutical injection device may comprise a main case, a piston, a drive motor, a buzzer, and a controller. The main case has a cartridge holder. The piston is inserted into a pharmaceutical cartridge mounted to the cartridge holder. The drive motor drives the piston. The buzzer emits a sound that tells the user to shake the pharmaceutical cartridge to mix or dissolve its contents. Before activating the drive motor and injecting the pharmaceutical, the control unit controls the buzzer so that a sound is emitted at specific intervals to prompt shaking.

1 - 34 . (canceled) 
     
     
         35 . A method for controlling a pharmaceutical injection device having a cartridge holder,
 said method comprising:   a shaking instruction step in which an instruction signal instructing a user to shake a pharmaceutical in a pharmaceutical cartridge mounted to the cartridge holder in order to mix or dissolve the pharmaceutical is issued at specific intervals so as to prompt a shaking operation prior to injection of the pharmaceutical;   an end detection step of detecting that the shaking operation instructed in the shaking instruction step has ended; and   an illumination step of illuminating an inside of the cartridge holder after the end detection step.   
     
     
         36 . The method for controlling a pharmaceutical injection device according to  claim 35 ,
 further comprising a determination step of determining whether or not the shaking prompted by the shaking instruction step is the proper shaking operation.   
     
     
         37 . The method for controlling a pharmaceutical injection device according to  claim 36 ,
 further comprising a notification step of notifying the user that the shaking operation has been determined to be proper.   
     
     
         38 . The method for controlling a pharmaceutical injection device according to  claim 35 ,
 further comprising a needle detection step of detecting whether or not a needle has been mounted for injecting the pharmaceutical in the pharmaceutical cartridge into a body,   wherein the shaking instruction step is performed when it has been detected in the needle detection step that the needle has not been mounted.   
     
     
         39 . The method for controlling a pharmaceutical injection device according to  claim 35 ,
 further comprising a shaking instruction display step of displaying an instruction to shake the pharmaceutical for mixing or dissolution, prior to the shaking instruction step.   
     
     
         40 . The method for controlling a pharmaceutical injection device according to  claim 35 ,
 further comprising a confirmation signal display step of displaying an instruction to confirm the mixing or dissolution state of the pharmaceutical; and   the confirmation signal display step occurring after the illumination step.
