Problems solved by technology

The biggest disadvantage of this product is that the power supply battery of the DBS implanted in the human body cannot supplement electric energy from outside the body, and can only be used for one time. change battery
However, it is obvious that this inductive external DBS has its disadvantages: it is susceptible to external interference
It is clear that the performance of deep brain stimulators using different rechargeable batteries can vary substantially
However, Chinese patent application 200410019937.X fails to specify what kind of rechargeable battery is used
In particular, alkaline rechargeable batteries require special charging management, but there is no mention in the patent application 200410019937.X. Accordingly, it can be considered that the technical disclosure of the claims for rechargeable batteries in the patent application 200410019937.X is insufficient
In fact, it can be argued that patent application 200410019937.X does not consider alkaline rechargeable batteries

Embodiment

[0044] The induction charging deep brain stimulator of the present invention adopts a specially made alkaline zinc-manganese rechargeable battery with a capacity of 2000mIh and a nominal voltage of 3 volts. There are welding points at the two ends of the battery for connection. Due to the small self-discharge of alkaline zinc-manganese rechargeable batteries, their capacity will lose about 10% after being stored for 3 years. Battery Considering the power consumption of the deep brain stimulator and the self-generation of the battery, the battery may be charged once every 1.5 to 2 years. Using a special charging mode, the charging current is a pulse current that decreases exponentially. When the battery voltage drops to 1.1 volts, start charging; when the battery voltage reaches 1.58 volts, stop charging. During charging, if the battery temperature is about to exceed 40°C, immediately reduce the charging current until the battery temperature does not rise any more. The chargi...

Abstract

The disclosed induced charge-type brain deep-part stimulator comprises: the in-vivo part with the in-vivo part of a dual-pole switch, an alkaline Zn-Mn dioxide cell, a monitor system for voltage and temperature of the cell, and a stimulating electrode; and the in-vitro part with a MPU, a pulse adjustment circuit, a charge-manage circuit, a in-vitro monitor system for voltage and temperature, and the in-vitro part of a dual-pole switch. This invention has strong resistance to interference, and has wide application, such as Parkinsonism, obsession and epilepsy.

Description

1. Technical field [0001] The invention relates to an induction charging deep brain stimulator using alkaline zinc-manganese rechargeable batteries, which is used for Parkinson's disease, torsion spasm, spastic torticollis and chorea. 2. Background technology [0002] Deep brain stimulator is commonly known as brain pacemaker, and its English name is Deep Brain Stimulator, or DBS for short. DBS has been widely used in the treatment of movement disorders, and is currently the most promising method for the treatment of Parkinson's Disease (PD). [0003] Parkinson's disease is one of the common diseases of the nervous system in middle-aged and elderly people. In my country, it is estimated that there are currently about 1.1 million to 1.5 million patients. Clinically adopted treatment methods include drug therapy and surgical treatment. However, people have gradually found that the curative effect of the drug decreases after long-term use, and serious side effects that are d...
