Embodiment Construction

[0040] The patient monitoring system 1 according to the invention is suitable for ECG measurements by means of capacitive measurements. As shown in FIG. 1 , the system 1 comprises a number of capacitive non-contact electrodes 2 arranged in the form of a matrix 3 . The electrodes 2 are adapted to be integrated with the bed 4 or the like. To this end, the electrode 2 is preferably fabricated as an electrode structure on a flexible substrate integrated with the bed 4 (e.g. by evaporating the electrode structure using a flexible foil), or the electrode 2 can even be woven into a bed sheet or the like, so as to form matrix 3. Each electrode 2 is individually selectable so that capacitive measurements are performed by means of the control unit 5 . The control unit 5 is connected to all electrodes 2 via a number of connection lines (not shown).

[0041] If a patient (not shown) is located on a bed 3, the system 1 is adapted to find the most suitable electrodes 2 for performing the...

Abstract

The invention relates to patient monitoring systems for monitoring cardiopulmonary function etc. by means of capacitive measurements. Furthermore, the invention relates to a method for monitoring cardiopulmonary function etc. by means of capacitive measurements. In order to provide a reliable technique for monitoring cardiopulmonary function etc., which is particularly suitable for home use, a patient monitoring system (1) for monitoring cardiopulmonary function etc. by means of capacitive measurements is proposed, said system (1) comprising a matrix (3) Many electrodes (2) arranged in the form, said electrodes (2) are suitable for being integrated with the bed (4) etc., each electrode (2) is individually selectable; ) etc., for determining the number of electrodes (2) by determining the capacitance of many electrodes (2); and for selecting a number of said The measured electrodes (2) and means (5) for performing capacitive measurements.

Description

technical field [0001] The invention relates to patient monitoring systems for monitoring cardiopulmonary function etc. by means of capacitive measurements. Furthermore, the invention relates to a method for monitoring cardiopulmonary function etc. by means of capacitive measurements. Background technique [0002] Bedside monitoring of parameters of patients with cardiac disease is commonplace in hospital settings. There is also a preferred method for measuring cardiac data or lung data in a home environment. To make this home monitoring system the least obtrusive, sensors that don't rely on direct skin contact are the most appealing. Therefore, the capacitive sensing method is most suitable for use with this system. [0003] Capacitive sensing of biological signals essentially relies on the capacitive coupling of "body electrodes" to the sensing capacitance. This coupling can vary with patient motion, sweat on the patient's skin, and intimacy of contact or body-to-sensi...
