Abstract

Automatically blocking and/or unblocking a computer-supported medical device in a system includes the medical device and a mobile terminal. The mobile terminal comprises a first wireless communication device, and the medical device comprises a second wireless communication device. The medical device is automatically shifted from a blocked state into an unblocked state, if when the first communication device establishes a wireless connection with the second communication device and the signal strength of a signal of from the first communication device to the second communication device exceeds a first threshold. The medical device is automatically shifted from an unblocked state into a blocked state when the first communication device establishes a wireless connection with the second communication device and the signal strength of a signal from the first communication device to the second communication device falls below a second threshold and/or the wireless connection is interrupted for longer than a predetermined time interval.

Dependent claims

A method for automatically unblocking or blocking a computer-supported medical device in a system, the system comprising the computer-supported medical device and a mobile terminal, wherein the mobile terminal comprises a first wireless communication device for wirelessly transmitting and receiving data and wherein mobile application software can be executed by the mobile terminal, wherein the medical device comprises a device computer and wherein the device computer comprises a second wireless communication device for wirelessly transmitting and receiving data, wherein driver software can be executed on the device computer, which can establish a wireless communication connection to the first communication device of the mobile terminal via the second communication device of the medical device, the method comprising:

automatically transferring the medical device from a blocked state into an unblocked state in response to:
establishing a wireless connection from the first communication device of the mobile terminal to the second communication device of the medical device, and
determining that signal strength of a signal of the first communication device of the mobile terminal, received by the second communication device of the medical device, exceeds a predetermined first threshold value, wherein the first threshold value is predetermined based on the physical size of the medical device and the first threshold value is lower for a first medical device that is physically larger than a second medical device, and
automatically transferring the medical device from an unblocked state into a blocked state in response to:
establishing a wireless connection from the first communication device of the mobile terminal to the second communication device of the medical device, and
determining that the signal strength of the signal of the first communication device of the mobile terminal, received by the second communication device of the medical device, falls below a predetermined second threshold value or
determining that the wireless connection is interrupted for longer than a predetermined first time interval.

4 more elements

A medical device comprising a device computer, wherein the device computer is capable of executing driver software which can establish a wireless communication link to a first wireless communication device of a mobile terminal by a second wireless communication device of the device computer, the second wireless communication device for wirelessly transmitting and receiving data, wherein the mobile terminal comprises the first wireless communication device for wirelessly transmitting and receiving data and wherein mobile application software can be executed by the mobile terminal, wherein:

the device computer is configured such that the medical device is automatically transferred from a blocked state into an unblocked state in response to the first communication device of the mobile terminal establishing a wireless connection to the second communication device of the medical device and signal strength of a signal of the first communication device of the mobile terminal, received by the second communication device of the medical device, exceeding a predetermined first threshold value wherein the predetermined first threshold value is based on the physical size of the medical device and the first threshold value is lower for a first medical device that is physically larger than a second medical device, and the medical device is automatically transferred from an unblocked state into a blocked state in response to the first communication device of the mobile terminal establishing a wireless connection to the second communication device of the medical device and the signal strength of the signal of the first communication device of the mobile terminal, received by the second communication device of the medical device, falling below a predetermined second threshold value or the wireless connection is interrupted for longer than a predetermined first time interval.
