UV Curing device for surgical adhesive
A client asked us if we could provide the electronics for a rechargeable UV wand for curing adhesives used in the body during surgery. We carried out a feasibility study. We identified solutions for the Electrical safety strategy, fault detection and tolerance. We identified components for power management including battery charger and monitor, safety interlock circuit, the UV LED and its drive circuit. We also estimated the size and cost of the programmable logic device required for the control logic, the required battery capacity and hence the battery size. We also estimated the PCB area and component height. We concluded that the combined constraints of the device size, functional requirements, storage time required between charging and total curing time per charge were feasible. After the successful feasibility study we carried out the detailed design and produced prototypes before the product was transferred to manufacture.
