Abstract
A wearable liquid supplying device for insulin injection is fixed on a user's body through a ring belt and includes a carrier body, a flow-guiding-and-actuating unit, a sensor, an air bag, a miniature air pump and a driving chip. The sensor measures sweat on human skin to detect a level of the blood glucose. The driving chip receives the glucose monitoring data and accordingly controls the actuation of the flow-guiding-and-actuating unit and the open/closed states of the switching valves. The miniature air pump is enabled to inhale gas into the air bag, so that the air bag is inflated and the ring belt contacts the human skin tightly. The flow-guiding-and-actuating unit is enabled to generate a pressure difference so that the insulin liquid is transported to a liquid guiding outlet through a liquid guiding channel and flows into the microneedle patch for being injected into the subcutaneous tissue.
