A physiological monitoring system can monitor health status of a subject having a wireless wearable device. The monitoring system can have distributed monitoring devices in communication with each other and a remote server. A monitoring hub of the system can establish wireless communication with the wearable device to wirelessly receive physiological data from the wearable device. The monitoring hub can transmit the physiological data to the remote server without processing the physiological data for centralized processing by the server. The server can generate patient alarms and cause the alarms to be output by the distributed monitoring devices. In instances when connection to the server is interrupted or lost, the monitoring hub and/or wearable device can continue, without interruption, monitoring the subject continuously and in real-time, such as for triggering of alarm conditions, until connection with the server is improved or reestablished.

A regional oximetry sensor can have a sensor head configured to secure to skin of a user and a stem extending from the sensor head. The sensor head can include an emitter configured to transmit optical radiation into the skin and at least one detector configured to receive the optical radiation after attenuation by blood flow within the skin. The stem can be configured to transmit electrical signals from the sensor head to a cable. A plurality of notches can extend from a perimeter of the sensor head towards an interior thereof. The plurality of notches can form a plurality of independently flexible cutouts in the sensor head configured to allow for movement of at least a portion of the skin of the user underlying the sensor head when the regional oximetry sensor is in use.

A system for monitoring hemodynamic status of a patient can include a transducer, an adapter and one or more monitor devices. The adapter may be in communication with the transducer and the one or more monitor devices. The adapter can be configured to receive and process data from the transducer such as unprocessed physiological data. The adapter can be configured to transmit data to the monitor device(s) such as processed and/or unprocessed physiological data. The adapter can be configured to generate, and transmit to the monitor devices(s), user interface data for rendering interactive graphical user interfaces to display information such as physiological information relating to a hemodynamic status of the patient. The adapter can be configured to receive and process, from the monitor device(s) user commands or instructions to control an operation of the system or its components.

A system for collecting physiological data from a patient is disclosed. The system includes a reusable module and a disposable module. The disposable module collects and transmits physiological data to the reusable module, which in turn transmits the physiological data to a patient monitoring system. The reusable module accesses operation data from the disposable module to validate the disposable sensor assembly. Optionally, the operation data includes sensor life data that may be used to determine life expectancy of disposable module. The disposable sensor assembly may store the physiological data for a predetermined length of time when there is no wireless communication established for the reusable module.

A non-invasive, optical-based physiological monitoring system is disclosed. One embodiment includes an emitter configured to emit light. A diffuser is configured to receive and spread the emitted light, and to emit the spread light at a tissue measurement site. The system further includes a concentrator configured to receive the spread light after it has been attenuated by or reflected from the tissue measurement site. The concentrator is also configured to collect and concentrate the received light and to emit the concentrated light to a detector. The detector is configured to detect the concentrated light and to transmit a signal representative of the detected light. A processor is configured to receive the transmitted signal and to determine a physiological parameter, such as, for example, arterial oxygen saturation, in the tissue measurement site.

An optical physiological sensor configured to be secured to a user's nose includes a first prong configured to be positioned proximate an outside portion of the nose, a second prong configured to be positioned proximate an inside portion of the user's nose, a winged portion coupled to the first prong and configured to contact tissue of the user, one or more emitters configured to emit light of one or more wavelengths into the tissue, and one or more detectors configured to detect at least a portion of the light emitted from the one or more emitters after attenuation through at least a portion of the tissue. In some configurations, the winged portion comprises a width that is greater than a width of the second prong. In some configurations, at least a portion of the winged portion is curved toward the second prong.

A sensor system for monitoring patients is provided. The sensor system includes a wireless charging dock, one or more patient sensors, and a processing module. The patient sensor is configured to collect patient physiological data and send the data to the processing module. The processing module wirelessly transmits the patient physiological data to a patient monitor system. The wireless charging dock is wirelessly and removably coupled to the processing module to wirelessly provide power for the processing module. The wireless charging dock is magnetically coupled to the processing module.

A system for monitoring a patient in a bed can include one or more hardware processors that can receive sensor data from a sensor attached to the patient. The one or more hardware processors can determine, based on the sensor data, an orientation of an upper portion of the patient's body relative to a plane that extends along a portion of the bed that is adjacent to a lower portion of the patient's body.

A first medical device can receive a physiological parameter value from a second medical device. The second physiological parameter value may be formatted according to a protocol not used by the first medical device such that the first medical device is not able to process the second physiological parameter value to produce a displayable output value. The first medical device can pass the physiological parameter data from the first medical device to a separate translation module and receive translated parameter data from the translation module at the first medical device. The translated parameter data can be processed for display by the first medical device. The first medical device can output a value from the translated parameter data for display on the first medical device or an auxiliary device.

A non-invasive physiological sensor system implemented as a smart watch or other wearable device includes an emitter for emitting light and a detector for collecting light after the light interacts with a tissue of a wearer. The system can measure light intensity at one or more radial distances to estimate attenuation parameter values that can be used to correct physiological parameter bias across subjects. In addition or alternatively, the system can determine whether a detector is positioned sufficiently proximate to an obstructing tissue (for example, an artery or vein) so as to cause inaccurate measurements by the detector.
