A system for configuring a second biomedical device in the same configuration as a first device. The first device is configured as desired and then is connected through a communication link to the second device to be configured. A teach mode is invoked in the first device and a learn mode invoked in the second device. The first device receives identification data from the second device, such as the model number and software revision number. If acceptable, the first device compares individual parameters against default values. The first device then sends only those parameters which differ from the default values. The second device will then load these parameters plus the default value of the other parameters. Both devices will indicate a successful transfer of data by means of a display. If the identification data do not match, the first device will provide a prompt and no configuration data will be sent to the second device. The devices will issue a prompt if after a configuration session has occurred, the operator attempts to switch off the power to the device to exit the configuration mode or attempts to enter the teach mode without first assigning a new configuration name. Each device includes a continuously powered display for continually displaying that assigned multi-character name, even during conditions of power-off.

Configuration control system for configuring multiple biomedical devices

An artery applanation actuator for use in a system for noninvasively determining the intra-arterial blood pressure of a user incorporates a fluid actuator to effect movement of a sensor. The movement of the sensor is effective for applanating an artery of interest and measuring the stress of the tissue overlaying the artery of interest. Alternative embodiments of the artery applanation actuator are presented wherein an electric motor is used to activate a rotating arm which has a sensor located thereon. The rotation of the arm causes the sensor to contact and press against the tissue overlying the artery of interest. The artery applanation actuator is presented having a protective sheath surrounding the sensor to protect the sensor against inadvertent contact.
