Abstract

The digital signal amplifier and acquisition system includes at least one catheter input module (CIM) configured to receive, route and digitize incoming analog cardiac signals from a number of catheters, as well as outgoing stimulator pulses. A plurality of CIMs are mechanically stacked and electrically daisy-chained and coupled with a mounting. The mounting platter is clamped to the bedrail and provides a single digital output cable to the base. The system also includes an acquisition device and the aforementioned base, which is configured to collect, filter and distribute the acquired data. Lastly an analog output module receives filtered digital signals from the base and is configured to reconstruct analog representations of such filtered digital signals for outside devices.

Claims

1-9. -9. (canceled)

10. A method of cardiology signal acquisition and amplification for distribution to at least a display, the method comprising the steps of:

collecting a set of analog cardiac data from a patient catheter with a cardiac input module;

converting the set of analog cardiac data directly to a set of digital data within the cardiac input module without amplification;

removably coupling a mount platter to a patient bed, such that the mount platter is coupled with he catheter input module and holds the catheter input module;

communicating the set of digital data from the cardiac input module to the mount platter;

communicating the set of digital data from the mount platter to a base unit, wherein the base unit is coupled with the patient bed and is configured to filter and distribute the set if digital data for illustration on the display,

wherein the mount platter is further configured to support a plurality of catheter input modules in a stacked configuration, further wherein the mount platter and each of the plurality of catheter input modules are electrically coupled to one another.

11. The method as claimed in claim 10, further comprising receiving a filtered set of digital data in an analog output module from the base unit, wherein the analog output module is configured to convert the filtered set of digital data to a reconstructed analog signal.

12. The method as claimed in claim 10, further comprising coupling an acquisition device with the base unit, the acquisition device configured to control the collection of a plurality of physiological parameters from a patient.

13. The method as claimed in claim 10, wherein the mount platter includes an emergency stimulator connector configured to provide a pulse to the patient catheter in the event of total system failure.

14. The method as claimed in claim 10, wherein the mount platter includes an auxiliary reference input configured to collect a non-catheter patient input.

15. The method as claimed in claim 10, wherein the catheter input module includes a plurality of inputs.

16. The method as claimed in claim 15, wherein the mount platter includes a test signal generator configured to test the functionality of any of the plurality of inputs of the catheter input module.

18. The method as claimed in claim 10, wherein the mount platter is fastened to a patient bed.
