Objective To design a residual liquid medicine verification and disposal robot to solve the problems of artificial intelligence patient controlled analgesia(AI-PCA)in standardization and efficiency of residual medication handling.Methods The residual liquid medicine verification and disposal robot consisted of a cabinet housing the AI-PCA,a lower-level control system,a human-machine interface system and a monitoring system.The cabinet contained components such as a storage module and a C-band UV lamp,while its exterior featured a fingerprint module,a card reader module and a capacitive touchscreen;the lower-level control system comprised a main control module,a near-field communication(NFC)identification module,a ZigBee wireless communication module,a host-to-lower-level communication module and peripheral control modules including an ultraviolet disinfection control module and a smart cabinet door lock control module;the human-machine interface system utilized a high-performance smart electric lock as its core drive unit and was compatible to recognition by fingerprint,NFC card,account password and iris/face;the monitoring system included a PTZ camera and a professional-grade network video recorder.Software development was carried out by C language for the lower-level control system and by JavaScript language for the host.Results The robot calculated the residual medication volume in a used AI-PCA,automatically drained the residual solution,generated a residual medication disposal report and then disinfected the AI-PCA pump head.Compared with traditional manual disposal measures,it had shorter time required to dispose of a single used AI-PCA while higher accuracy in the reporting of residual medication verification and disposal,higher execution rate of two-person verification and higher rate of successful AI-PCA disposal,with statistically significant differences(P<0.05).Conclusion The application of the robot enables the used AI-PCA to comply with national standards for the disposal of residual anesthetic and psychotropic medications,which contributes to increasing medical staffs'efficiency and decreasing the risk of cross-infection in hospitals.[Chinese Medical Equipment Journal,2026,47(5):37-43]
