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. A data acquisition system in communication to receive a set of analog cardiac data from a catheter of a patient situated on a support structure, the system comprising:

at least one catheter input module configured to receive the set of analog data from a patient and to convert the set of analog cardiac data to a set of digital data, wherein the catheter input module includes a plurality of connectors configured to receive analog data, and further wherein the catheter input module is configured to be physically and electrically coupled with additional catheter input modules;

a mount platter removably coupled to a patient bed in close proximity to the patient, and further coupled in communication to receive the set of digital data from the at least one catheter input module, wherein the mount platter is removably coupled to the at least one catheter input module and supporting the at least one catheter input module; and

a base unit coupled in communication to receive the set of digital data from the mount platter and further configured to filter and distribute the set of digital data, wherein the base unit is physically coupled to the patient bed, wherein the mount platter includes an emergency stimulator connector coupled with a STIM input and configured to provide a pulse to the catheter from the STIM input, wherein the pulse from the emergency stimulator connector is provided in the event of total system failure.

2. The system as claimed in claim 1, further comprising an analog output module electrically coupled with the base unit and configured to receive a filtered set of digital data from the base unit, and further configured to convert the filtered set of digital data to a reconstructed analog signal.

3. The system as claimed in claim 1, further comprising an acquisition device coupled with the base unit, the acquisition device configured to control the collection of a plurality of physiological parameters from a patient.

4. The system as claimed in claim 1, wherein the mount platter includes an auxiliary reference input configured to collect a non-catheter patient input.

5. The system as claimed in claim 1, wherein the at least one catheter input module includes a plurality of inputs.

6. The system as claimed in claim 5, 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.

7. The system as claimed in claim 5, further comprising a plurality of catheter input modules, wherein each of the plurality of catheter input modules is electrically and mechanically coupled to each other and with the mount platter.

8. A data acquisition system in communication to receive a set of analog cardiac data from a catheter of a patient situated on a support structure, the system comprising:

at least one catheter input module configured to receive the set of analog data from a patient and to convert the set of analog cardiac data to a set of digital data, wherein the catheter input module includes a plurality of connectors configured to receive analog data, and further wherein the catheter input module is configured to be physically and electrically coupled with additional catheter input modules;

a mount platter removably coupled to a patient bed in close proximity to the patient, and further coupled in communication to receive the set of digital data from the at least one catheter input module, wherein the mount platter is removably coupled to the at least one catheter input module and supporting the at least one catheter input module; and

a base unit coupled in communication to receive the set of digital data from the mount platter and further configured to filter and distribute the set of digital data, wherein the base unit is physically coupled to the patient bed, wherein the at least one catheter input module includes a plurality of inputs, and further 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.

9. The system as claimed in claim 8, further comprising an analog output module electrically coupled with the base unit and configured to receive a filtered set of digital data from the base unit, and further configured to convert the filtered set of digital data to a reconstructed analog signal.

10. The system as claimed in claim 8, further comprising an acquisition device coupled with the base unit, the acquisition device configured to control the collection of a plurality of physiological parameters from a patient.

11. The system as claimed in claim 8, wherein the mount platter includes an auxiliary reference input configured to collect a non-catheter patient input.

12. The system as claimed in claim 8, further comprising a plurality of catheter input modules, wherein each of the plurality of catheter input modules is electrically and mechanically coupled to each other and with the mount platter.
