Abstract
An ultra-miniaturized wireless-controlled patch-type drug pump and a production method thereof, in the field of biomedical engineering device technology, are disclosed. The pump utilizes near-field communication (NFC) technology commonly found in smartphones to power the circuit. It injects drug into patients' bodies via volume alteration of a thermal expansion material and a gas generated by an electrolytic electrode, attaining pre-meal bolus and basal rate drug infusion. The drug pump has a relatively simple structure, a small size, and no need for an internal power supply, thereby alleviating at least some of the burden on patients and enhancing the comfort and convenience of wearing the pump. Meanwhile, it can be controlled through a smartphone application, simplifying the operation(s) of the pump and providing users with a precise and convenient drug injection approach.
