Liquid injection device and medical apparatus

Abstract

A liquid injection device includes an injection unit which injects a liquid, a liquid supply instrument which supplies the liquid to the injection unit, and a control unit which controls operation of the injection unit and the liquid supply instrument, wherein the injection unit includes a distal end portion where a nozzle for injecting the liquid is formed, and a body portion in which the distal end portion is removably loaded, at the distal end portion, a distal end-side memory is provided in which first startup data is written, and the control unit is a control unit which reads and writes the first startup data from and to the distal end-side memory in the distal end portion loaded in the body portion and manages use time of the distal end portion based on the first startup data that is read out.

         11 . A liquid injection apparatus comprising:
 an injection unit which includes a liquid injecting nozzle and an actuator to inject liquid from the nozzle; and   a controller configured to be connected with the injection unit and to manage a use time of the actuator on the basis of a drive time of the actuator.   
     
     
         12 . The liquid injection apparatus according to  claim 11 , wherein
 the controller outputs a warning when the drive time of the actuator exceeds an allowable time.   
     
     
         13 . The liquid injection apparatus according to  claim 11 , wherein
 the controller configured to manage the use time of the actuator on the basis of a number of times of the actuator is driven.   
     
     
         14 . The liquid injection apparatus according to  claim 13 , wherein
 the controller outputs a warning when the number of times of the actuator is driven exceeds an allowable number of times.   
     
     
         15 . The liquid injection apparatus according to  claim 11 , wherein
 the injection unit includes
 a distal end portion where the nozzle is formed, 
 a body portion in which the distal end portion is removably loaded, and 
 a first memory connected to the body portion and in which a drive time data related to the drive time of the actuator is written. 
   
     
     
         16 . A controller configured to be connected with a liquid injecting unit which includes a liquid injecting nozzle and an actuator to inject liquid from the nozzle, the controller comprising:
 a processor configured to manage a use time of the actuator on the basis of a drive time of the actuator.   
     
     
         17 . The controller according to  claim 16 , wherein
 the processor outputs a warning when the drive time of the actuator exceeds an allowable time.   
     
     
         18 . The controller according to  claim 16 , wherein
 the processor configured to manage the use time of the actuator on the basis of a number of times of the actuator is driven.   
     
     
         19 . The controller according to  claim 18 , wherein
 the processor outputs a warning when the number of times of the actuator is driven exceeds an allowable number of times.
