Heart pacemaker with noncontact power supply function

Abstract

The invention discloses a heart pacemaker with a noncontact power supply function. The pacemaker comprises a storage battery, an external pacemaker circuit and an internal energy receiving apparatus, wherein the storage battery and the external pacemaker circuit are connected, the external end of the external pacemaker circuit is provided with a wireless ECG sensor, the wireless ECG sensor is installed at an external heart, the external energy receiving apparatus is arranged in the skin of a left shoulder, the external pacemaker circuit is connected with the internal energy receiving apparatus through electromagnetic coupling, and the internal energy receiving apparatus is connected with a heart through an electrode. According to the invention, the fatigue degree of the heart is determined through measurement of ECG signals by use of a heart rate variation feature, and amplitude of pulse voltages needing to be provided and conduction stimulation time are controlled; an ECG signal detection filtering circuit, the storage battery and a noncontact power supply primary circuit are installed outside, and only a noncontact power supply secondary circuit is installed in the body of a patient, such that the volume of a built-in circuit is greatly reduced, and regular operation for replacement of the storage battery is unnecessary.

Description

technical field [0001] The invention relates to the technical field of cardiac pacemakers, in particular to a cardiac pacemaker with a non-contact power supply function, capable of monitoring and pacing the beating state of the heart outside the body, and belongs to the field of medical electronics. Background technique [0002] The cardiac pacemaker is used for auxiliary stimulation of human heart pacing. It is usually installed on the skin of the patient's body under the left shoulder. The pacemaker is placed under the skin of the left chest to make the skin prop up to form a pouch. It is placed under the clavicle of the left chest The venipuncture leads to the electrode, the electrode is connected to the heart from the vein, and the threaded hook at the front end is inserted into the inner side of the heart for fixation, such as figure 1 shown. Because traditional pacemakers are usually relatively large, the patient's skin cannot be closed for a long time after installat...

AI Technical Summary

Problems solved by technology

[0004] Some scholars have also proposed pacemakers based on wireless power supply, but these pacemakers still need built-in batteries, wireless communication circuits, and detection circuits, and the size of pacemakers cannot be reduced to the extent that the skin is completely closed after surgery.
