Energy recovery device

A module for use in a processing process for a medical product, system and/or instrument having an integrated or connectable, exchangeable and chargeable energy storage, the module being configured to be held or supported during the processing process in a washer disinfector as a processing device, the module comprising:

• a connection for connecting the module to an existing fluid circuit of the processing device;
• a conduit as a fluid conduit for guiding a fluid flow at the connection into and through the module;
• a port portion;
• at least one connection port provided at the port portion and configured to hold the medical product, system and/or instrument such that the medical product, system and/or instrument can be flushed by fluid flowing in through the connection port;
• an energy production device configured to be arranged on or in the fluid conduit, and arranged to produce energy from kinetic energy of the fluid flow for charging the energy storage;
• and
• an inductor arranged in an area in which the energy storage of the medical product, system and/or instrument is located in a connected state, and which is configured to charge the energy storage via energy harvested from the fluid flow via the energy production device, during operation of the washer disinfector.
