Physiological measurement device

A patient monitoring system comprising:

• a portable patient monitoring device comprising:
• a pulse oximetry sensor configured to be attached to a digit of a patient, the pulse oximetry sensor including at least:
• a light emitter configured to emit light into a tissue site of the digit of the patient;
• and
• a light detector configured to output a sensor signal responsive to at least a portion of the emitted light after attenuation by tissue of the tissue site;
• a housing configured to be secured to an arm of the patient, wherein the housing comprises at least:
• a top surface;
• a bottom surface opposite the top surface;
• and
• a side surface that joins the top surface and the bottom surface;
• a strap mountable to the housing, the strap configured to secure the housing to the arm of the patient such that the bottom surface of the housing is flush with the arm of the patient;
• a cable extending from the pulse oximetry sensor and configured to electrically convey the sensor signal, wherein:
• the cable connects with the housing at a position on the side surface of the housing,
• the side surface of the housing runs perpendicular to the long axis of the arm of the patient when the housing is secured to the arm of the patient,
• the position is located at a mid-section of a height of the housing, and
• the cable is configured to at least partially extend from the side surface of the housing along a path perpendicular to the side surface of the housing;
• one or more signal processors configured to generate, responsive at least in part to the sensor signal, a transmit signal including information indicative of measurements of physiological parameters including at least oxygen saturation and pulse rate;
• and
• a signal transmitter configured to wirelessly transmit the transmit signal to a receiver computing system;
• and
• the receiver computing system configured to:
• adapt or process the transmit signal to be usable by the receiver computing system for displaying measurements of oxygen saturation and pulse rate on a display of the receiver computing system;
• and
• cause display of the measurements of the physiological parameters on a display of the receiver computing system.
