Title:
AN ARTIFICIAL PANCREAS SYSTEM WITH A PIEZOELECTRIC PUMP
Document Type and Number:
WIPO Patent Application WO/2023/101647
Kind Code:
A3
Abstract:
This invention relates to an artificial pancreas system (10) providing closed-loop glucose control that automatically determines the amount of insulin needed and provides basal or bolus insulin release, and in its most basic form, comprises: a glucose measurement unit (20) comprising a glucose sensor (21), a first wireless data communication module (22) and a first battery (23); at least one control unit (31) adapted to determine, on the basis of data measured by the glucose meter (20), the amount of insulin to be pumped and to generate control signals accordingly; a second wireless data communication module (32); a piezoelectric driven pump (30) having a second battery (33), at least one amplifier (34) for amplifying control signals output from the control unit (31), at least one insulin reservoir (35), and a nozzle (37) and a diffuser (38), and comprising at least one first piezoelectric disc (36) ensuring that the insulin in the reservoir (35) connected to the nozzle (37) is sucked and pumped from the diffuser (38) in line with said control signals.
