Wirelessly-charged cardiac pacing device

Abstract

The invention provides a wirelessly-charged cardiac pacing device, comprising a housing, as well as a transducer, a current adapting circuit, a power module and a pacemaker which are arranged inside the housing. The transducer is used for converting input acoustic wave signals into electrical signals; the current adapting circuit is used to convert the electrical signals into direct current signals; the power module is used to receive the direct current signals for charging and supply power to the pacemaker; the transducer comprises a transducing plate, a transducer shell and an acoustically transparent membrane; the housing sleeves the transducing plate and is connected to the housing; the transducing plate, the transducer shell and the acoustically transaprent membrane form an enclosed chamber; a heat-insulating liquid is arranged inside the chamber. The transducer shell is arranged on the transducing plate; the chamber is formed through the acoustically transaprent membrane at the end of the transducer shell; the heat-insulating liquid is arranged inside the chamber; therefore, heat isolation is provided for the transducing plate, and injury to the human body can be lessened.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wireless charging cardiac pacemaker. Background technique [0002] Cardiac pacemaker is an electronic therapy device implanted in the body. It uses a pulse generator to release electric pulses powered by batteries, and through the conduction of wire electrodes, it stimulates the myocardium in contact with the electrodes to excite and contract the heart, thereby achieving The purpose of treating cardiac dysfunction caused by certain arrhythmias. Among them, the transducer in the pacemaker is a key. In the cardiac pacemaker, the transducer converts the focused acoustic wave signal into an electrical signal. During the focusing process, the temperature at the focus may occur due to the large focusing energy. If it is too high, it will bring the risk of injury to the human body. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the...
