IMPLANTABLE HEART MONITOR Russian patent published in 2022 - IPC A61B5/333 

FIELD: medical equipment.

SUBSTANCE: implantable heart monitor comprises a body, an information memory, and a control circuit with a controller provided with diagnostic software, a permanent storage apparatus, a RAM, a timer. The power supply equipment of the heart monitor includes a battery, an energy consumption compensation system and a transceiver for communication with an external stationary programming apparatus. The energy consumption compensation system is made in the form of a receiving module for wireless transmission of supply energy, integrated hermetically into the body of the heart monitor, provided with an inverter and an receiving inductance coupling coil. The receiving coil is connected with the internal power supply subsystem of the heart monitor via the inverter. The module for wireless transmission of supply energy can receive electric power through the receiving coil from the transmitting coil of the external transmitter for wireless transmission of supply energy. The receiving module for wireless transmission of supply energy comprises, connected in series, a receiving coil, a diode rectifier, an adjustment transistor and a key, the output whereof is connected with the positive electrode of the battery and constitutes the supply voltage output. The receiving module also comprises six capacitors and an operational comparing amplifier. The control input of the key is the control input of the receiving module.

EFFECT: energy consumption of the built-in battery is reduced, as well as the overall dimensions, energy use, and heat release, and the level of interference introduced by the power source is reduced due to the wireless transmission of supply energy for the purpose of ensuring the energy use of the equipment of the heart monitor from an external source using electromagnetic waves during communication with the programming apparatus due to the wireless transmission of supply energy from an external radio frequency transceiver, wherein the alternating magnetic field formed by an external transmitting inductance coil generates an induction current through an implantable receiving coil.
