Abstract:
Fluid accumulation in the body is an indicator for heart failure. The fluid accumulation causes a change in the magnetic permeability. The change in magnetic permeability is determined with an inductance, wherein the body is encircled by a conductive loop (110) that has the inductance. A change in the determined inductance is indicative for a change in fluid accumulation. The conductive loop is coupled to an oscillator (600) which oscillator frequency is dependent on the inductance. A change in the oscillator frequency is indicative for a change in fluid accumulation. When the conductive loop is placed around the chest a change in the average oscillator frequency is indicative for a change in fluid accumulation.
Abstract:
A device for combined heart rate and respiration measurement of a patient. This device comprises a strain gauge (2) providing a strain gauge signal in dependence of detected strain, an elastic carrier (3) for carrying the strain gauge (2), and two stickers (5) for sticking the device on the patient's chest (9). The strain gauge (2) and the stickers 5 are arranged on the elastic carrier (3) in such a way that movements of the patient's chest (9) due to heart beat and/or respiration lead to a varying strain gauge signal. This way, low cost monitoring in the normal ward is provided, capturing the basic vitalsigns pulse and respiration.

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.

A heartbeat monitoring device (2) comprises: - a number of electrodes (3.1, 3.2) for sensing an ECG signal (SO) of a user (5), - a signal processing means (14) for processing a signal (S2) derived from the ECG signal and adapted to extract information related to the heartbeat of the user from the derived signal, - a standardized wireless communication module (11) for transmitting said heartbeat-related information to an external device (17). In the proposed heartbeat monitoring device the signal-processing means is implemented on a communications processor of the standardized wireless communication module.
Abstract:
An electrical device with an impedance detector comprises a path from a supply voltage to a second voltage. The path comprises segments having electrical impedances, at least one of which is to be ascertained, and a measuring vertex. The impedance detector further comprises a discriminator connected to the measuring vertex, arranged to evaluate a measuring voltage observed at said measuring vertex, and situated in a path between a further supply voltage and a third voltage. The discriminator draws no significant current from said supply voltage if the to be ascertained impedance remains above a threshold value. In this manner, in a standby mode, a zero-power supervision of a condition when to resume operation can be achieved.
