New Description: [New Technology Field] This creation provides a technical field of intrusion into plastic heart rhythm regulators, especially the wireless transmission system that provides an implantable rhythm regulator. [Prior Art] The heart rate regulator is a sophisticated electronic device that senses the electrical 'change' of the heart. When the patient's heartbeat slows or irregularities occur, the heart rhythm regulator emits a weak current to stimulate The heart is used to correct heart rhythm and maintain heart function; while the circuit and power system of the earliest used rhythm regulators are external to the body and are quite large, which causes inconvenience to the patient's actions: However, with the advancement of technology, The size of the conventional heart rate regulator is also gradually reduced to a size that can be implanted into the human body to solve the problem of the limitation of the patient's action; however, after the heart rhythm regulator is implanted into the human body, the problem of battery power replenishment is As a result, although the electric_cell of the rhythm regulator can be used for 5 to 15 years, the medical system is developed today, and the patient usually survives for a longer period of time after surgery, so the battery of the rhythm regulator Replacement becomes a problem; the conventional rhythm regulator battery must be replaced every time it is replaced - the surgery removes the old battery to replace the new battery, which This kind of practice not only causes the physiological burden of the patient, but also causes the expenditure of medical resources. Therefore, in view of the above-mentioned problems of a more ideal and practical structure, how to construct a new structure, and to develop the expectations of consumers, M368427 is also the relevant industry to strive to develop breakthrough goals and directions.
