Abstract

A telepresence device may autonomously check patients. The telepresence device may determine the frequency of checking based on whether the patient has a risk factor. The telepresence device may include an image sensor, a thermal camera, a depth sensor, one or more systems for interacting with patients, or the like. The telepresence device may be configured to evaluate the patient's condition using the one or more sensors. The telepresence device may measure physiological characteristics using Eulerian video magnification, may detect pallor, fluid level, or fluid color, may detect thermal asymmetry, may determine a psychological state from body position or movement, or the like. The telepresence device may determine whether the patient is experiencing a potentially harmful condition, such as sepsis or stroke, and may trigger an alarm if so. To overcome alarm fatigue, the telepresence device may annoy a care provider until the care provider responds to an alarm.

First claim

The invention claimed is:

1. A non-transitory computer-readable storage medium including computer-readable instruction code that, when executed, causes a telepresence device to perform operations for autonomously checking a plurality of patients, the operations comprising:
receiving, by a processor, indications of each of the plurality of patients; receiving, by the processor, medical data, via a communications network, for at least one of the plurality of patients;
determining, by the processor, a frequency of checking each of the plurality of patients with the telepresence device based on the received medical data, wherein checking each of the plurality of patients with the telepresence device includes autonomously moving a camera of the telepresence device to capture a series of images of each of the plurality of patients;
responsive to an instruction from the processor, autonomously moving the camera of the telepresence device to capture a first series of images of at least one of the plurality of patients at a first time;
determining, by the processor, a heart rate of the at least one of the plurality of patients by analyzing the first series of images to detect changes in skin color of the at least one patient captured in the first series of image; and
autonomously moving the camera of the telepresence device to capture at least a second series of images of the at least one of the plurality of patients at a second time after a period of time defined by the determined frequency of checking has elapsed.

2. The non-transitory computer-readable storage medium of claim 1 , wherein the method further comprises detecting one or more risk factors in the received medical data, and wherein determining the frequency comprises determining the frequency based on the one or more risk factors.

3. The non-transitory computer-readable storage medium of claim 2 , wherein detecting one or more risk factors comprises receiving an indication of a diagnosis requiring more frequent checking.

4. The non-transitory computer-readable storage medium of claim 1 , wherein the medical data includes an indication of the frequency.
