Medical device with an energy supply having at least two energy sources

摘要

According to one embodiment, a medical device may include an energy supply. The energy supply may include a lithium-ion polymer battery including at least two battery stacks and a control unit. One of the at least two battery stacks may be a backup energy source. The control unit may monitor and control the energy supply such that when the control unit detects a fault in the at least two battery stacks, the control unit disconnects a faulty battery stack. The energy supply may be rechargeable. Each of the at least two battery stacks may include a positive potential terminal, a negative potential terminal and one or more battery cell.

主权项

1. A method of monitoring and controlling an energy supply of a medical device, the energy supply comprising a battery comprising at least two battery stacks, wherein one of the at least two battery stacks is a backup energy source, said method comprising providing the medical device with a control unit which monitors and controls the energy supply such that when the control unit detects a fault in the at least two battery stacks, the control unit disconnects a faulty battery stack of the at least two battery stacks and uses the backup energy source, and with a reservoir for a fluid, the reservoir comprising a capacity, wherein the capacity of the reservoir and remaining running time of the energy supply are synchronized such that change or refill of the reservoir is required at the same time as change or recharge of the energy supply.
