Implanted device wireless power supply control method, in-vitro processing device and system

The invention discloses an implanted device wireless power supply control method, an in-vitro processing device and an in-vitro processing system, and belongs to the technical field of biomedicine. Through a sectional type power supply voltage control method, the voltage is gradually increased to the maximum value in a boosting section, and large load impact of a resonance circuit of the in-vitro processing device during starting is relieved; the maximum value of the power supply voltage is gradually reduced to a rated value in the voltage reduction section, large load impact of a resonance circuit of the in-vivo implanted device during starting is relieved, power judgment is carried out in combination with current monitoring of the resonance circuit, transient thermal damage and bioelectricity or electrochemical interference are avoided, and the reliability of the in-vivo implanted device is improved. And high-efficiency and stable electric energy transmission is realized on the premise of ensuring biological safety.

What the filing appears to be about, read by published rules from its title, abstract and classification codes (A61N1/37512, A61N1/37514, A61N1/3787, G01R19/25, G05B19/0423). The claims define what a patent protects, and they are not read here.

Implant electronics

An implant has room for very little, so functions that fill a rack in the laboratory have to fit on a chip. The problem behind it: fitting channel count, computing and safety functions into a volume and a heat budget the body accepts.

Packaging

Body fluid destroys unprotected electronics. An implant meant to last has to stay sealed for years while passing every channel through its wall. The problem behind it: a seal that lasts as long as the patient needs it, at a size that leaves room for the channels.

Power

A wire through the skin is a standing infection risk, and a battery sets how long a device runs and how large it is. The problem behind it: enough power through the skin without heating it, and without a connector that breaks the skin.

Why the layer matters to the field, not a judgement of this filing. A patent family shows that protection was sought. It does not show that the technology was built, is used in a product, or works in people. The whole stack

Dates as the offices published them. Office records are in the offices' own words and are a selection: refusals, lapses and withdrawals, and records that name an owner. Each concerns one member of the family, not the family as a whole, and another member in the same office may stand. Whether a patent is in force today is not assessed.
