A method and system that allows various sensor types to be connected to common input ports of a patient monitor. The system includes a data acquisition module that identifies the type of sensor connected to each one of a plurality of input ports. Once the sensor type has been identified, the data acquisition module configures amplification circuits and input circuits such that the output signal from the sensor is properly received and amplified within the patient monitor. The properly amplified output signal from the sensor, along with a sensor identifier, is supplied to a controller of the patient monitor. In this manner, the patient monitor can identify the type of sensor connected to each input port and properly display the conditioned output signal from the sensor.

Patient monitor sensor type auto configuration

A patient monitor includes a data connector configured to connect to a corresponding data connector of an approved physiological data acquisition device to provide data transmission to and from the approved physiological data acquisition device, and a power connector configured to connect to a corresponding power connector of the approved physiological data acquisition device to provide power to the approved physiological data acquisition device. The patient monitor further includes a control module configured to detect connection of a corresponding power connector of an unidentified device at the power connection port and/or a corresponding data connector of the unidentified device to the data connector, and provide a limited power amount to the unidentified device through the power connector. The control module performs an authentication process to determine that the unidentified device is the approved physiological data acquisition device, and then provides a full power amount through the power connector to the approved physiological data acquisition device.

System and method for controlling authentication of a physiological acquistion device by a patient monitor

A monitoring system and method for monitoring signals from an implantable medical device are disclosed. The monitoring system and method include a monitor configured to detect a radio frequency artifact from the signals of the implantable medical device and circuitry for processing the radio frequency artifact from the signals of the implantable medical device.

Detection of function of implanted medical devices

A data acquisition system can include an acquisition device and a receiving device. The acquisition device includes inputs that receive data from sensors connected to a subject, a wireless and/or a wired transmitter that transmits data received by the inputs, and a housing carrying at least some of the components of the acquisition device. The housing may be wearable by a patient. The acquisition device may be switchable between a tethered data transmission mode and an untethered data transmission mode. The receiving device includes a receiver that receives data transmitted by the acquisition device, and may include an output that outputs data to a host. The system may be configured to transmit data from the data acquisition device to the local monitor point-to-point. The system is particularly useful for monitoring high acuity patients that may or may not require ambulation.

Wireless subject monitoring system

A cable management and data acquisition method and apparatus to store system data and data from activity sensors when the sensors are disconnected from a monitoring system. The apparatus includes a housing, a first connection port operable to receive information from one or more activity sensors, a device interface coupled to the first connection port, a non-volatile memory coupled to the device interface; and an output port coupled to the device interface. The cable management and data acquisition apparatus may also include a digital-to-analog converter to convert analog signals from sensors to digital signals. Preferably, the device interface is an application specific integrated circuit (&ldquo;ASIC&rdquo;) that communicates with a signal processor in the monitoring processor. The signal processor responds to commands or messages from the monitoring processor and reads data from and writes data to the memory in the cable management and data acquisition apparatus through the ASIC. The cable management and data acquisition apparatus prevents the loss of patient data when a patient monitoring system is disconnected from the activity sensors attached to a patient, such as might occur when a patient is moved from one location to another. Data stored in the memory of the apparatus can be readily retrieved when the patient arrives to the new location so as to maintain a record of identification data and permit the tracking of trends.

Multiple-link cable management apparatus

A signal acquisition method comprises the steps of recording ECG data signals on a tape in a first direction through a first high pass filter; and acquiring the data from the tape in an analyzer in a reverse direction through a second high pass filter having the same effective characteristics as the first filter.
