BIOMETRIC POWER SUPPLY ELEMENTS WITH POLYMER ELECTROLYTES Russian patent published in 2019 - IPC A61F9/00 H01M10/26 H01M10/28 H01M2/02 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely to the means of energy supply of medical devices. Biomedical device contains an electroactive component; battery, including: anode current lead; cathode current lead; anode; polymer electrolyte, wherein the polymer electrolyte contains poly(vinylidenefluoride-hexafluoropropylene), lithium salt and ionic liquid; a transition metal oxide cathode, containing a lithium salt; and the first biocompatible encapsulating layer, wherein the first biocompatible encapsulating layer encapsulates at least said electroactive component and battery. Method of manufacturing a battery includes the steps in which a cathode current lead film comprising titanium is produced; the cathode current lead is covered with a carbon coating; the suspension of the transition metal oxide is applied on the carbon coating, wherein the suspension contains a lithium salt; applied layer of transition metal oxide is dried; a polymeric electrolyte containing poly(vinylidenefluoride-hexafluoropropylene), lithium salt and ionic liquid is formed; the polymer electrolyte is layered on the applied layer of the transition metal oxide; polymer electrolyte is dried; the metal foil is layered on the polymer electrolyte; metal foil, a polymer electrolyte, applied layer of a transition metal oxide and a cathode current lead are sealed in a biocompatible sealing film; and the battery element is isolated from polymer electrolyte, applied layer of a transition metal oxide and a cathode current lead, sealed in the biocompatible encapsulating metal foil film. Energy saving method provided by the work of the biomedical device.

EFFECT: use of a group of inventions can improve performance and aspects of biocompatibility of battery.
