A patient monitoring system comprising:
- a patient monitor configured to display information regarding a patient, wherein the patient monitor comprises a first port;
- a cable comprising a proximal end and a distal end, and further comprising a cable body that extends between the proximal and distal ends, wherein the proximal end of the cable comprises a first connector configured to electrically couple with the first port of the patient monitor;
- an electrical interface configured to receive analog signals from a patient parameter sensor;
- and
- a first circuit including a front-end processing module configured to condition the analog signals from the patient parameter sensor and convert the analog signals into digital signals, wherein the first circuit is external to the patient monitor, wherein the first circuit is closer to the distal end of the cable than it is to the proximal end of the cable when the system is in an assembled state and the cable is fully extended to limit a distance over which the analog signal is transmitted over the cable, and wherein the first circuit is at a distance of no less than about 3.0 feet from the first connector and no more than about 3.0 feet from the distal end when the system is in an assembled state and the cable is fully extended.
A system configured to provide digital signals to a patient monitor, the system comprising:
- a cable comprising a proximal end and a distal end, and further comprising a cable body that extends between the proximal and distal ends, wherein the proximal end of the cable comprises a first connector configured to couple with a patient monitor;
- an electrical interface configured to receive analog signals from a patient parameter sensor;
- and
- a circuit configured to communicate with the electrical interface, wherein the circuit is configured to condition the analog signals from the patient parameter sensor and convert the analog signals into digital signals and to transmit the digital signals through a length of the cable body to the first connector, wherein the first circuit is at a distance of no less than about 3.0 feet from the first connector and no greater than about 3.0 feet from the distal end when the system is in an assembled state and the cable is fully extended to limit a distance over which the analog signal is transmitted over the cable, and wherein the length of the cable body through which the circuit is configured to transmit digital signals to the first connector is no less than about 3.0 feet.
A system configured to provide signals to a patient monitor, the system comprising:
- a cable comprising a proximal end and a distal end, and further comprising a cable body that extends between the proximal and distal ends, wherein the proximal end of the cable comprises a first connector configured to couple with a patient monitor;
- an electrical interface configured to receive signals from a patient parameter sensor;
- a circuit in communication with the electrical interface, wherein the circuit is configured to condition the analog signals from the patient parameter sensor and convert the analog signals into digital signals and to transmit the digital signals through a length of the cable body to the first connector, and wherein the first circuit is at a distance of no less than about 3.0 feet from the first connector and no greater than about 3.0 feet from the distal end when the system is in an assembled state and the cable is fully extended to limit a distance over which the analog signal is transmitted over the cable;
- and
- an actuator electrically coupled with the circuit, wherein the actuator is closer to the distal end of the cable than it is to the proximal end of the cable when the system is in an assembled state and the cable is fully extended and the actuator is configured to allow selection of an operational state of the circuit.
A method of communicating a signal to a patient monitor, the method comprising:
- providing a cable having a proximal end coupled with the patient monitor, wherein the cable comprises a circuit and an actuator;
- receiving an indication of an operational state of the circuit via the actuator;
- obtaining an analog signal via a patient parameter sensor;
- conditioning and converting the analog signal to a digital signal according to the operational state of the circuit;
- and
- transmitting the digital signal through a length of the cable, wherein the length of the cable through which the digital signal is transmitted is greater than a distance through which the analog signal is transmitted to limit a distance over which the analog signal is transmitted over the cable, and wherein the length of the cable through which the digital signal is transmitted is no less than about 3.0 feet.
