Embodiment 1

[0055] This embodiment provides an intracardiac energy harvesting device 100. The intracardiac energy harvesting device 100 has a size and shape suitable for being implanted into a cardiac cavity through interventional surgery. The intracardiac energy harvesting device 100 is applied to into the heart cavity to collect the biomechanical energy generated by the beating heart. Interventional surgery refers to interventional surgery in medicine. It is a minimally invasive treatment using modern scientific and technological means. Under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments can be introduced into the human body to treat diseases in the body. For diagnosis and local treatment. For example, the intracardiac energy harvesting device 100 can be implanted into the heart chamber through a catheter through femoral vein puncture.

Abstract

The invention discloses an intracardiac energy collection device and an implantable electronic medical device, which belong to the field of medical equipment. The intracardiac energy collection device includes: a casing; a fixing mechanism arranged on the casing, and the fixing mechanism is configured to fix the casing on the heart inside the cavity so that the housing can move with the beating of the heart; the nanogenerator module is packaged in the housing, and the nanogenerator module is configured to output electrical energy in response to the movement of the housing as the heart beats; the power management module is packaged in the housing , the power management module is used to manage the electric energy output by the nano generator module. The heart energy harvesting device disclosed by the present invention can be implanted into the heart to collect biomechanical energy generated by the beating heart through minimally invasive interventional surgery. The surgical trauma is small, the heart will not be damaged, and infection can be effectively avoided.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intracardiac energy harvesting device and an implanted electronic medical device. Background technique [0002] With the continuous development of medical technology, there are more and more miniature implantable electronic medical devices that can meet the diagnosis and detection of various diseases. Implantable pulse generators such as cardiac pacemakers and brain pacemakers are widely used in medical diagnosis and treatment. However, almost all implantable medical devices are powered by energy storage media such as batteries. Lithium batteries, as the most mature power supply, have been applied in clinical practice, but they still have an unavoidable shortcoming - limited battery capacity. As a result, the working life of implanted electronic medical devices is affected. When the power of the storage medium decreases or is exhausted, the implanted medical devices cannot work...
