Wearable liquid supplying device for human insulin injection

A wearable liquid supplying device for human insulin injection, comprising:

• at least one main body having at least one accommodation space;
• at least one ring belt having two ends respectively connected to two opposite sides of each of the at least one main body;
• at least one carrier body disposed in one of the at least one accommodation space of one of the at least one main body;
• at least one liquid storage chamber formed in each of the at least one carrier body to store insulin liquid and having at least one liquid storage outlet;
• at least one flow-guiding-and-actuating unit constructed on each of the at least one carrier body and having at least one liquid guiding channel in fluid communication with each of the at least one liquid storage outlet of each of the at least one liquid storage chamber, each of the at least one liquid guiding channel being further in fluid communication with each of the at least one liquid guiding outlet, wherein after each of the at least one flow-guiding-and-actuating unit is actuated, the insulin liquid is transported out from each of the at least one liquid storage chamber and discharged through each of the at least one liquid guiding outlet;
• at least two switching valves disposed in each of the at least one liquid storage outlet and each of the at least one liquid guiding outlet, respectively;
• at least one microneedle patch attached on a side of each of the at least one flow-guiding-and-actuating unit to seal each of the at least one liquid guiding outlet, each of the at least one microneedle patch having plural hollow microneedles adapted to be punctured into a human skin as a minimally invasive procedure such that the insulin liquid is injected into subcutaneous tissue;
• at least one sensor disposed on each of the at least one carrier body and adapted to be in contact with the human skin to detect a level of the blood glucose by measuring sweat on the human skin, after which the sensor accordingly generates glucose monitoring data;
• at least one air bag disposed on an inner side of each of the at least one ring belt;
• at least one miniature air pump in fluid communication with each of the at least one air bag;
• and
• at least one driving chip disposed on each of the at least one carrier body, controlling the actuation of each of the at least one flow-guiding-and-actuating unit and each of the at least one miniature air pump, and controlling an open/closed state of each of the at least two switching valves, each of the at least one driving chip receiving the glucose monitoring data from each of the at least one sensor;
• wherein when each of the at least one ring belt is worn on the human skin, each of the at least one driving chip controls each of the at least one miniature air pump to actuate, so that each of the at least one air bag is inflated and each of the at least one ring belt is in close contact with the human skin, by which the plural hollow microneedles of each of the at least one microneedle patch are punctured into the human skin, wherein when each of the at least one sensor detects a specific level of blood glucose, each of the at least one driving chip controls each of the at least one flow-guiding-and-actuation unit to actuate, and controls each of the at least two switching valves to be in the open state, by which the insulin liquid within each of the at least one liquid storage chamber is transported out from each of the at least one liquid storage chamber, discharged through each of the at least one liquid guiding outlet and guided into each of the at least one microneedle patch, such that the insulin liquid is injected into the subcutaneous tissue through the plural hollow microneedles.
