  • Patent number: 10304322
    Abstract: An apparatus comprising a wireless communication device for enabling the remote control of a medical apparatus The apparatus includes a remote control enable device comprising a transmitter and one or more switches, actuatable by enable buttons. The buttons allow an operator to close the switch(es), causing the transmitter to send a status signal related to the status (open or closed) of the switch(es), to a receiver configured to communicate said status signal to a control unit. The control unit verifies the signal on a number of criteria. When all required criteria have been met, remote control of the medical apparatus is allowed. In an embodiment the remote control enable device is configured to maintain the power supply to a transmitting chip sufficiently long, upon opening a switch, so that a check can be performed on the correct functioning of the switch after the switch has been opened.
