Embodiment Construction

[0021] In the drawings, like reference numerals refer to like components.

[0022] figure 1 A graph is shown with days prior to hospitalization on the horizontal axis and impedance, specifically thoracic bioimpedance of heart failure patients, on the vertical axis. figure 1 Adapted from the article "Intrathoracic Impedance Monitoring in Patients With Heart Failure Correlation With Fluid Status and Feasibility of Early Warning Preceding Hospitalization" by Cheuk-ManYu, Li Wang, Elaine Chau et al. (Circulation, August 9, 2005, pp. 841-848) . Measure chest impedance at least once a day. At day 0, the patient's condition changes such that the patient is hospitalized. It can be seen from the chart that the patient's thoracic impedance has begun to decrease about 14 days before hospitalization. When changes in thoracic impedance are detected, patients can be treated 10-14 days before hospitalization, thereby potentially avoiding hospitalization.

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.

Description

technical field [0001] The present invention relates to a system and method for positioning electrodes on a patient's body by non-medically trained personnel. Background technique [0002] Precise positioning of electrodes on a patient's body is indispensable for a large number of medical examinations. A prominent example is ECG (electrocardiogram) examination and bioimpedance measurement. [0003] If such an examination is performed in a home setting, there may be no medically trained personnel, then the patient, or a person without medical training, will have to undertake tasks that may require some medical and technical background, such as the placement of electrodes. place. [0004] In heart failure examinations and / or chronic heart failure treatments, it may be necessary to perform bioimpedance measurements on a daily basis, comprising positioning several electrodes on the patient's body performed by the patient at home. In order to obtain meaningful results from suc...
