Abstract: A method for monitoring the blood pressure of a patient, comprising the following steps: determining a pulse arrival time signal from the patient 2 based on the pulse wave velocity method; determining an accelerometer signal from the patient 2; and triggering an additional measure or deriving a blood pressure value, taking into account the pulse arrival time signal and a DC component of the accelerometer signal. In this way, a possibility for monitoring the blood pressure of a patient is provided with which false alarms and/or unnecessary additional cuff-based blood pressure measurements can be avoided.

Abstract: A method comprising the step of using a plurality of doppler radars disposed on the seat belt or integrated into the seat belt for monitoring vital body signs of a person seated in a seat of a motor vehicle is disclosed. The disclosed method unobtrusively monitors vital body signs like heart rate and respiration of the person seated in the motor vehicle. A number of safety applications as well as wellness applications can be enabled. Examples are detection of momentary sleep of the driver, vital sign monitoring in case of an accident as well as relaxation exercise using biofeedback to reduce stress for drivers.

Abstract: The invention relates to the detection of electrical and mechanical cardio-vascular activities of a patient, especially to early decompensation detection of congestive heart failure patients (CHF). The device according to the invention comprises a transmitter for transmitting electromagnetic signals of a predefined frequency into the chest of the patient, a Doppler radar sensor 1 for detecting a Doppler radar signal reflected in the patient's chest, and an ECG unit 3 for capturing an ECG signal of the patient's heart. This device allows for simultaneous detection of electrical and mechanical cardio-vascular activities of a patient which can be used in an easy and reliable way and which allow for implementation in a hand-held or wearable device.

Abstract: For obtaining a sequence of mutually comparable measurement results, it is desirable to position a number of electrodes on a patient body (10) at substantially the same position for each measurement. As such measurements may be performed every day, it is desirable for a patient to be able to perform the measurement at home, for example. The present invention provides a method and system (100) for enabling a not medically trained person to position the electrodes at substantially the same position for each measurement. The method comprises capturing an image (126) of the patient (10) and comparing the image (126) with a reference image (128). In the reference image (128), the electrode positions (130) are indicated. The electrode positions (130) of the reference image (128) are superimposed on the image (126) of the patient (10). An indicator system (134) indicates the position (130) of the electrodes such that the patient (10) may position the electrodes correctly.

Abstract: In order to provide an easy-to-use technique for measuring blood pressure and/or other vital signs of a subject, a sensor for detecting the passing of a pulse wave from a subject's arterial system is suggested, the sensor being adapted to be located at a sensing position on the exterior of the subject's body, characterized in that the sensor comprises a number of electrical coils for generating an inductive coupling to the subject's body in a way that the properties of said inductive coupling change if a pulse wave passes a screened volume underneath the sensing position, and a circuit connected to the number of electrical coils, said circuit being adapted to detect said property changes of the inductive coupling.

Abstract: In a medical pulse oximetry sensor (10) at least two light emitting diodes (16, 18) are disposed to emit red light and infrared light through a portion of a subject's anatomy with a typically high oxygenated blood throughput. Typically, this area is also relatively narrow, to allow the light to pass through the area with acceptable attenuation, such as a finger or an earlobe. Light emitted from the LEDs (16, 18) is incumbent upon an integrated circuit (22) printed from a single CMOS substrate (21). The integrated circuit (22) includes all preprocessing and post-processing elements needed to convert the detected light signals into a pulse oximetry measurement. These elements include a photodetector (20), a photo pre-amplifier (40), a sampler/holder (42), an analog to digital converter (44), a microprocessor (46) a rangefinder (48), a timing control circuit (50) and an LED control circuit (52).
