A system for providing open application programming interface (API)-based medical information may not only allow examination subjects to easily measure their blood pressures and check their accurate analysis results, but also health-care services and manufacturers of electronic apparatuses or portable medical devices may easily call an open API without developing a special algorithm and special system for analyzing a measured bio signal and estimating medical information, thereby easily providing processed medical information to users.

The present invention is directed to a self-contained hand-held device that obtains vital signs accurately, simultaneously, comfortably, and quickly. Unlike currently used devices that require trained personnel and the attachment of sensors to the different parts of the patient's body, this device can obtain all vital signs+ECG and pulse-ox by being held by the patient for approximately half a minute. The device contains sensors on the hand-held unit as well as on the individual/disposable mouthpiece. The method of the present invention includes simultaneously acquiring the following measurements: temperature, pulse rate, breathing rate, blood pressure, electrocardiogram, and pulse-ox waveform and blood oxygen level.

Long-term electrocardiographic and physiological monitoring over a period lasting up to several years in duration can be provided through a continuously-recording subcutaneous insertable cardiac monitor (ICM). The sensing circuitry and the physical layout of the electrodes are specifically optimized to capture electrical signals from the propagation of low amplitude, relatively low frequency content cardiac action potentials, particularly the P-waves that are generated during atrial activation. In general, the ICM is intended to be implanted centrally and positioned axially and slightly to either the left or right of the sternal midline in the parasternal region of the chest. Additionally, the ICM includes an ECG sensing circuit that measures raw cutaneous electrical signals and performs signal processing prior to outputting the processed signals for sampling and storage.

Each sensing electrodes is configured to be coupled eternally to a patient and to detect one or more ECG signals. The one or more processors are configured to receive at least one electrode-specific digital signal for each of the plurality of sensing electrodes, determine a noise component for each of the electrode-specific digital signals, analyze each of the noise components for each of the plurality of sensing electrodes, generate electrode matching information for each sensing electrode of the plurality of sensing electrodes based upon analysis of each of the noise components, determine one or more sensing electrode pairs based upon the electrode matching information, and monitor each of the one or more sensing electrode pairs for ECG activity of the patient.

A device may include a housing, a light-permeable electrode, a computing device, and a display or other light-processing element. The display or other light-processing element may be positioned at least partly within the housing. The device components may be arranged to permit passage of light through the light-permeable electrode and relative to the light-processing element. The computing device may utilize electrical activity signal information from the light-permeable electrode to determine electrocardiogram (ECG) information or other information about the body of a user of the device. For example, the computing device may cause such ECG information to be projected through the light-permeable electrode by the display or other light-processing device and/or obtain additional information based on light received through the light-permeable electrode by the display or other light-processing device.

An electronic device, such as a watch, has a housing to which a carrier is attached. The carrier has a first surface interior to the electronic device, and a second surface exterior to the electronic device. A set of electrodes is deposited on the exterior surface of the carrier. An additional electrode is operable to be contacted by a finger of a user of the electronic device while the first electrode is positioned against skin of the user. The additional electrode may be positioned on a user-rotatable crown of the electronic device, on a button of the electronic device, or on another surface of the housing of the electronic device. A processor of the electronic device is operable to determine a biological parameter of the user based on voltages at the electrodes. The biological parameter may be an electrocardiogram.
