PATIENT MONITORING DEVICE
First Claim
1. A measurement device for use with one or more external devices, the measurement device comprising:
- a reflective gradient configured to reflect radiation, reflectivity of reflective gradient varying along a gradient direction; and
a circuit connecting a processor to one or more sensors and a communication mechanism, each of the one or more sensors comprising an emitter and a corresponding detector positionable relative to the reflective gradient along the gradient direction, the processor being configured to;
instruct the emitter of each of the one or more sensors to emit radiation, at least a portion of the radiation emitted by the emitter of ones of the one or more sensors positioned adjacent a portion of the reflective gradient being reflected by the portion of the reflective gradient toward the corresponding detector,instruct the detector of each of the one or more sensors to detect a reflected amount of radiation, andinstruct the communication mechanism to transmit to the one or more external devices measurement information for each of the one or more sensors based on the reflected amount of radiation detected by the detector of each of the one or more sensors.

Abstract
A patient monitoring device to be worn on a limb of a patient. Some embodiments of the patient monitoring device include at least one sensor assembly configured to detect a measurement indicating a distance around the patient'"'"'s limb and a communications subassembly configured to transmit the measurement to at least one external computing device. Other embodiments of the patient monitoring device include at least one sensor assembly configured to detect a measurement indicating a distance around the patient'"'"'s limb and at least one processor configured to detect whether the distance around the patient'"'"'s limb has increased indicating edema. Some embodiments include an accelerometer configured to detect device orientation and/or patient activity information. The patient activity information may be analyzed by an external computing device and/or the patient monitoring device to determine whether the patient'"'"'s activity level has declined indicating a medical problem.
