Abstract

The invention relates to an electrical stimulator system with a charging function. The electrical stimulator system includes an in vivo system and an in vitro system. The in vivo system includes a stimulating unit, at least one pair of stimulating electrodes, a perception unit, at least one pair of perception electrodes and one set of sensors, an in vivo charging unit, an in vivo communication unit, a signal storage and processing unit, and a control and voltage conversion unit. The in vitro system includes a charger and a processor. According to the invention, the electrical stimulator system is a fully implantable electrical stimulation system capable of achieving high energy stimulation and wireless charging and can be used to enhance the contractile force of large organs, such as heart and stomach; and can be applied to the treatment of chronic heart failure, obesity, type 2 diabetes and other diseases.

Description

technical field [0001] The invention relates to an electrical stimulator system, in particular to an electrical stimulator system with a charging function for improving organ contractility. Background technique [0002] Chronic heart failure is the "final destination" of cardiovascular disease, a malignant disease with high mortality rate, 40% of patients die within 12 months, and 65% of patients die within 60 months. Not only that, but patients with chronic heart failure have the worst quality of life of all chronic diseases. Among the patients with systolic chronic heart failure, 30% belong to the wide QRS group. For these patients, a CRT (Cardiac Resynchronization Therapy, CRT) can be implanted. For the remaining 70% of patients, there is currently no effective drug or management device. [0003] Type 2 diabetes is a lifelong disease. Once sick, need life-long medical treatment. According to the "Guidelines for the Prevention and Treatment of Type 2 Diabetes in China ...
