1. A wireless communication system for wireless medical data transmission between first and second items of medical equipment which are configured to communicate with each other non-wirelessly with a first communication protocol, the system comprising:

  • a first wireless device including;

    a first medical equipment interface arranged to provide connection to the first item of medical equipment;

    a first wireless interface;

    one or more first processors programmed to perform a protocol adaptation from at least one of;

    the first communications protocol of incoming data received at the first medical equipment interface to a second communications protocol of data to be wirelessly transmitted by said first wireless interface, and,the second communications protocol of incoming data received at the first wireless interface and the first communications protocol of data to be transmitted through the first medical equipment interface to the first item of medical equipment; and

    ,a second wireless device including;

    a second medical equipment interface arranged to provide connection to the second item of medical equipment;

    a second wireless interface which wirelessly communications with the first wireless interface using the second communications protocol;

    one or more second processors programmed to perform a protocol adaptation from at least one of;

    the second communication protocol of incoming data received at the second wireless interface and the first communication protocol of data to be transmitted through the second medical equipment interface,the first communication protocol of incoming data received at the second medical equipment interface to the second communication protocol of data to be transmitted through said second wireless interface, and,said protocol adaptations comprising individual or combined filtering, gathering, partitioning, prioritizing, or discarding said incoming data;

    wherein said first wireless device and said second wireless device communicate through their respective wireless interfaces;

    wherein the first and second wireless devices further include;

    first and second parameter memories configured to store a configuration file containing an adaptation specification pertaining to the protocol adaptation;

    wherein said one or more first and second processors are further programmed to;

    in a configuration state, receive the configuration file via one of the medical equipment interface and the wireless interface and load the configuration file in the parameter memory;

    read the configuration file containing the adaptation specification that pertains to said protocol adaptation; and

    perform said protocol adaptation in compliance with said adaptation specification;

    wherein said configuration file describes said protocol adaptation by defining at least one mapping between a data pattern at said medical equipment interfaces and a data pattern at said wireless interfaces, said mapping comprising a transformation rule defining a transformation from said data pattern at said medical equipment interfaces to said data at said wireless interfaces or vice versa.
