Artificial heart signal energy transfer method based on digital coil pair array and transfer paper

Abstract

The invention discloses an artificial heart signal energy transfer method based on a digital coil pair array and transfer paper. Identical mXn coil pairs are respectively arranged on transmitting paper and receiving paper according to a matrix form array, coils are arrayed correspondingly mutually, the coils on the transmitting paper are connected with an energy supply module, and the coils on the receiving paper are connected with a signal demodulation module and a combination unit. Only one of each digital coil pair on the transmitting paper transmits energy, the different digital coils are electrified to respectively stand for a signal 0 and a signal 1, and the mXn coil pairs complete transmission of mXn bits of signals at one step. Electric energies transmitted by the mXn coil pairs on the receiving paper are collected and gathered, and supply power for an artificial heart after being rectified, simultaneously, an electric signal of each coil in the mXn coil pairs is detected, and accordingly transmitted signals are obtained. The artificial heart signal energy transfer method and the transfer paper have the advantages that the signals are transmitted at high speed on the basis that energy transmission efficiency is not affected, a circuit structure is simple, cost is low, and an implanted artificial heart cannot be restrained by a percutaneous cable again.

Description

technical field [0001] The invention relates to an artificial heart signal energy transmission method, in particular to an artificial heart signal energy transmission method based on a digital coil pair array and a transmission paper. Background technique [0002] As the number one killer of human health, cardiovascular disease kills tens of millions of people every year, accounting for one-third of the global mortality. There are about 10 million patients with heart failure in China, and more than 2 million patients die of end-stage heart failure every year. Heart transplantation is the only effective way to treat end-stage heart failure, but only dozens of patients have the opportunity to receive living donor hearts every year. transplant. As a substitute for the living heart, the artificial heart is expected to have an industry scale of more than 100 billion US dollars. The energy transfer system is a bridge connecting the action of the implanted artificial heart and th...

Problems solved by technology

Japanese scholar Mamoru Takahashi proposed to load the information to be transmitted on the energy wave at a high frequency, and use the amplitude modulation method to achieve the same channel transmission of energy information through the same pair of coils; however, the amplitude modulation method transmits the amplitude of the energy The value change will inevitably affect the efficiency of energy transfer; Japanese scholar Nozomi Tamura proposed to transfer information and energy separately, by placing the center line of the coil that transfers information and energy vertically, so that the transferred magnetic field does not interfere with each other. One plane will inevitably lead to bulky implants, which will affect the implantation; German Aerospace Center proposes a method of transmitting energy and information in separate modules, using magnetic coupling technology to transmit energy separately, and adding wireless radio frequency modules to achieve information transmission. This method signals and information The energy does not interfere with each other, but adding a radio frequency module will inevitably increase the volume of the implanted device
