Abstract: A sensor holder to be applied on an appendage of a subject is disclosed herein. The sensor holder includes a substrate with at least a first location for a first sensor component, the substrate surrounding a hollow for receiving the appendage along a longitudinal axis of the hollow. The substrate is gradually thickening when drawing away at least a predetermined distance from the at least first location for the first sensor component along a perpendicular direction of the substrate in relation to the longitudinal axis of the hollow.

Abstract: A magnetic connector system comprising a first connector part having at least one contact and at least one magnetic element and a second connector part having at least one contact and at least one magnetic element, wherein the magnetic elements of the connector parts are arranged to create an attractive force to keep the contacts of the connector parts engaged when the connector parts are proximally located, wherein there is a pivot point at an edge area of the first connector part and the second connector part, the pivot point being located between the first connector part and the second connector part when the connector parts are engaged, and wherein the first connector part and/or the second connector part are arranged to turn around the pivot point when the first connector part and the second connector part are disconnected from each other by a non-axial force.

Abstract: Sensor and method for measuring amount of substance in blood. The sensor comprises a base element having a surface, and at least one light emitting diode emitting at pre-determined wavelength, and a photodetector which is sensitive to the pre-determined wavelength. The at least one light emitting diode comprises at least one emissive layer having been printed onto the surface.

Abstract: Sensor arrangement for measuring anesthesia parameters from the head of a patient the sensor arrangement comprising a base element and an array of electrodes and an optical sensor for monitoring substances in tissues. In the sensor arrangement all electrodes and sensors are connected to a single connector or a series of connectors attached to the base element for connecting the sensor arrangement to a patient monitor.

Abstract: An electrode for obtaining a biopotential signal from the skin of a subject. The electrode comprises an adhesive element, an electrode body, an electrically conductive electrode pad, a sponge element, soaked with conductive gel, and means for skin abrasion. The means for skin abrasion comprises abrasion elements forming an integrated structure with the electrode pad, the abrasion elements being so dimensioned that the sponge element prevents the abrasion elements from touching the skin when biopotential signals are measured and enables mechanical contact between the skin and the abrasion elements when the electrode pad is pushed towards the skin. The electrode body is made flexible to enable intentional movement of the electrode pad relative to the adhesive element.

Abstract: A sensor for measuring biopotential signals from the skin of a patient. The sensor comprises a carrier having a top surface positioned contiguous with the skin of the patient when the sensor is applied to the patient's skin and a bottom surface facing away from the patient when the sensor is applied to the patient's skin. The carrier has further plurality of spikes extending from the top surface for being inserted into the skin of the patient when the sensor is applied to the patient's skin. The sensor further comprises means for obtaining the biopotential signal and for making the biopotential signal available externally of the sensor. The carrier is manufactured of non-conductive material and the non-conductive material is made conductive to form electrical connection between the top and bottom surfaces of the carrier.
