Abstract
The present disclosure describes example systems, methods, apparatuses, and medical devices for obtaining physiological parameter data from a wearable patient monitoring device. An example patient monitoring device can include an emitter and a detector. The emitter can emit light through tissue of a patient. The detector can sense the light after it passes through and is attenuated by the tissue and can generate a signal indicative of the sensed light. When the patient monitoring device is attached to or worn by the patient, the emitter and detector are aligned such that the light from the emitter travels through an opening between a first bone and a second bone of the patient prior to being sensed by the detector.
Claims19
A wearable patient monitoring device comprising:
- an emitter configured to emit light towards a limb of a patient;
- a detector configured to sense the light after it passes through and is attenuated by tissue of the limb of the patient and to generate a signal indicative of the sensed light;
- a wearable housing configured to engage with the limb of the patient and to support the emitter and the detector, the wearable housing comprising a hinge and at least two rigid components coupled by the hinge, wherein a shape of the wearable housing is based at least in part on a placement of the hinge and shapes of the at least two rigid components, the shape of the wearable housing configured to:
- limit lateral or rotational movement about the limb;
- and
- facilitate alignment of a light path between the emitter and the detector with an opening between a first bone and a second bone of the limb of the patient;
- and
- a processor configured to receive the signal indicative of the sensed light to determine that the light path are not aligned with the opening between the first bone and the second bone of the limb of the patient based on the signal indicative of the sensed light and provide a notification to a user indicating misalignment.
A method comprising:
- providing a wearable patient monitoring device that includes a wearable housing, a processor, an emitter, and a detector, the wearable housing comprising a hinge and at least two rigid components coupled by the hinge, wherein a shape of the wearable housing is based at least in part on a placement of the hinge and shapes of the at least two rigid components,
- wherein during attachment of the wearable patient monitoring device to a limb of a patient the shape of the wearable housing is configured to limit lateral or rotational movement about the limb and facilitate alignment of a light path between the emitter and the detector with an opening between a first bone and a second bone of the limb of the patient,
- wherein the processor configured to receive a signal indicative of a sensed light to determine that the light path is not aligned with the opening based on the signal indicative of the sensed light and provide a notification to a user;
- receiving a signal from the detector, the signal being responsive to light emitted by the emitter and detected by the detector after the light passes through the opening between the first bone and the second bone;
- and
- determining a physiological parameter based at least in part on the signal.
