Abstract:
Traditional medicine injection is done by medical professionals. Patients need to see doctors or nurses for medicine injection. This brings inconvenience for the patients and increases the cost of medical care. Many senior patients with chronical diseases may need to inject multiple medicines everyday. Remembering the sequence of what medicine to inject at what time is not an easy job. Some medicine (such as insulin for diabetic patients) need to be delivered with precise dosage control according to the patient’s real-time need. Manual injection by rough estimation may lead to under-dose or overdose. All these made the medicine delivery a complicated and challenging task. In this research, a smart drug delivery system which can automatically inject the medicines according to preprogrammed sequence is proposed. It consists of a micropump, micro drug reservoirs and microneedle array integrated with a smart control circuitry. It can deliver multiple medicines with precise dosage control and proper timing. It allows the patients to injection medicine anytime anywhere automatically without human interference. It makes the medicine injection a worry-free process. The proposed smart drug delivery system leads to improved efficiency and it is expected to bring revolutionary change to the current medicine delivery technology.
