Automation takes more and more space in hospitals. It helps realize savings in terms of money and time. Considering that, the CHU Sainte-Justine, a pediatric hospital located in Montreal, asked for the development of an automated system for reconditioning of bulk liquid oral medications. The reconditioning, done manually at the moment, consists of filling oral syringes, one by one. A hospital like CHU Sainte-Justine has to fill more than 500 different syringes each day, which leads to safety risks for the patients (associated with errors in the preparation) and health problems for the pharmacy technicians. Considering that there is no automated system on the market to manage that task, this project consists of designing the handling systems, the filling system, the consumable managing system and the inspection system. The handling system is built of two serial robot arms and two electric parallel grippers. An innovative universal adaptor is developed to accommodate the wide variety of bottle shapes and sizes. The filling system is built using three electrical actuators, two linear and one rotary, holding the bottles and the syringes while filling the syringes without the robot intervention. The consumable managing system use metallic loader to store the six different volumes of syringes and a metallic rack and the universal bottle adaptor to store the bottles. At last, the inspection system uses a pattern recognition algorithm to find air bubbles in the syringes. Those bubbles could alter the volume of medication in the syringe. To conclude, the oral syringes filling system is a viable and cost effective for children’s hospitals. The next step of the project consists of finding the money needed to build a working prototype.
