Title:
ウェアラブルヒトインスリン注射用液体供給装置
Document Type and Number:
Japanese Patent JP7008607
Kind Code:
B2
Abstract:
A wearable liquid supplying device (100) for human insulin injection is fixed on a body of human through a ring belt (2) and includes a substrate (3), a flow-guiding-and-actuating unit (5), a sensor (8) and a driving chip (9). The substrate (3) has a liquid storage chamber (4). The flow-guiding-and-actuating unit (5) has a liquid guiding channel (51) in communication with a liquid storage outlet (41) of the liquid storage chamber (4) and a liquid guiding outlet (52). The sensor (8) measures a blood glucose level and generates measured data correspondingly. The driving chip (9) receives the measured data from the sensor (8) and controls the actuation of the flow-guiding-and-actuating unit (5) and the open/closed states of the switching valves (6). The flow-guiding-and-actuating unit (5) is enabled to generate a pressure difference so that the insulin liquid is transported to the liquid guiding outlet (52) through the liquid guiding channel (51) and flows into the microneedle patch (7) for allowing the microneedles (71) to inject the insulin liquid into the subcutaneous tissue.
