Abstract: In one aspect, a computer-implemented method includes receiving signals corresponding to wavelengths of light detected by an optical sensor placed in proximity to a patient's body, and for each received signal: separating the signal into an AC signal and a DC signal; separating the AC signal into component signals; analyzing the component signals through a fractional phase transformation to identify a desired component signal and harmonic signals associated with the desired component signal; smoothing the desired component signal, the harmonic signals, and the DC signal; and combining the smoothed desired component signal, the smoothed harmonic signals, and the smoothed DC signal to generate a modulation signal. A modulation ratio signal is generated based on the modulation signals derived from the signals, and a peripheral oxygen saturation (SpO2) of the patient's body is determined based on the modulation ratio signal.

Abstract: Methods, systems, and apparatus for detecting configuration for a patient worn sensor assembly are described. In one aspect a method includes receiving, by a computer system, sensor assembly data for a particular sensor assembly, accessing, by the computer system, sensor assembly identifier information defining a plurality of sensor assembly identifiers, where each sensor assembly identifier is associated with a respective sensor assembly, identifying, by the computer system and based on the sensor assembly data, a particular sensor assembly identifier for the particular sensor assembly, and determining, by the computer system, configuration information for the particular sensor assembly based on the particular sensor assembly identifier.

Abstract: A pulse oximeter includes a curved holder. A flexible substrate is coupled to a curved inner surface of an outer portion of the curved holder. A light emitter, a light receiver, and a reinforcement are coupled to a curved inner surface of the flexible substrate. The reinforcement is curved to extend in conformance with the curved form of the flexible substrate. The material of the reinforcement has a Young's modulus that is larger than the Young's modulus of the material of the outer portion and the Young's modulus of the material of an inner portion.

Abstract: A patient worn sensor assembly for detecting, recording, and communicating patient vital signs can be integrated into a garment to be worn by the patient. A lead assembly can be integrated into a garment to connect electrodes in contact with the skin of a patient to a sensor assembly that collects vital sign information from the electrodes. The lead assembly can be multi-layered and can include, for example, two outer anti-static satin fabric layers as top and bottom layers, muslin fabric insulator layers adjacent to the anti-static satin fabric layers, shield layers that include muslin with silver fabric adjacent to the insulator layers, and an inner layer of fabric with conductive thread (or alternatively conductive thread not integrated with other fabrics, or a layer that is substantially composed of conductive thread).

Abstract: Streamlined and integrated patient care and health information management systems and methods for reducing the need for costly, near constant patient monitoring by providing system components that allow healthcare professionals to view the most important data for a number of patients in varying physical locations in a seamless manner are disclosed. Various components of the system can be used to monitor patients; measure, record, and track vital signs; and coordinate patient care in an automated fashion. Patients that have a achieved a relatively stable condition during a recovery process, but who still require or would benefit from near constant, or frequent vital sign monitoring can be provided with one or more body worn vital sign sensors. These patient worn sensors can track vital sign and other information about patients, including patient movement, activity, and sleep patterns.

Abstract: A system for providing realtime medical data to a client device regardless of a type of a client device's platform. The system uses different types of connections to establish a connection between the client device and the system and to transfer realtime medical data between the client device and the system. For example, a Hypertext Transfer Protocol (HTTP) connection can be used to establish a connection between the client device and the system and a websocket connection can be used to transfer realtime medical data between the client device and the system. By using an HTTP connection, the system can initially establish a connection between the system and any client device compatible with an HTTP connection.

Abstract: A patient worn sensor assembly for detecting, recording, and communicating patient vital signs includes several structural features that can provide increased signal quality, reduction in signal noise, increased patient comfort, increased reliability, and increased adhesion to a patient's skin. The patient worn sensor can track vital sign information such as blood pressure, body temperature, respiratory rate, blood oxygenation, heart rhythm (via ECG), heart rate, blood glucose level, and hydration (bio-impedance) levels. The sensor can also track and record additional information about patients, including patient movement, activity, and sleep patterns.
