Abstract: An inductive sensing device comprises first (16) and second (24) loops, the first loop (16) being coupled with a capacitor to form a resonator circuit (20), and the resonator circuit and second loop being coupled via an active buffering component (28). The active buffering component provides voltage to current amplification, and an output of the buffering component drives a current in the second loop. Conductive lines forming each of the first and second loop parts are radially spaced apart.

Abstract: A wearable gear (100) for holding a physiological sensor for monitoring a subject, such as a pulse oximeter. Said wearable gear being configured to automatically adjust the maximal length such that the predefined tension is obtained regardless of the size of the body part of the subject. The wearable gear comprises a tensioning element (102) having a maximal length, a holding unit for holding the physiological sensor, the wearable gear further comprises a tension mechanism for tensioning the tensioning element to a predefined tension when at least partially around a body part of the subject, wherein the tension mechanism comprises i) a first part comprising a resilient material, and ii) a second part comprising a non-resilient material, and wherein the first part and the second part mechanically cooperate with each other to automatically adjust the maximal length such that the predefined tension is obtained regardless of the size of the body part.

Abstract: In a sensor system (12), output signals of at least one PPG sensor (14) are processed to derive a modified pulse amplitude variation (PAV) value, being modified to take account of a baseline variation of the PPG sensor output signal. In particular, the modified PAV is derived through performing a modification step (42) in which either: a baseline variation of the PPG sensor output is derived and combined with a previously derived PAV, or, a PPG sensor output is first processed to perform baseline variation compensation, in advance of then deriving a PAV from the compensated signal.

Abstract: A device for supporting determination of return of spontaneous circulation, ROSC, during an associated cardiopulmonary resuscitation, CPR, procedure which is being performed on an associated patient. A sensor is used to sense a physiological signal of the patient. Frequency analysis of the signal is carried out to extract dominant fundamental frequency components in the signal. From this analysis it is possible to determine that there has been a potential ROSC.

Abstract: An apparatus (20) for use in inductive sensing includes a loop antenna (26) and a signal generator (24) for driving the antenna, these forming a resonator circuit (22). The resonator circuit is drivable in a drive state in which the antenna is driven at resonance to thereby generate electromagnetic signals. The arrangement further includes a switching means (28) for switchably inhibiting the drive state of the antenna This allows in use controllable switching of the antenna in and out of the drive state to thereby control switching signal generation on and off.

Abstract: A device is configured for tracking e.g. the diastolic blood pressure in a patient. The device applies a pressure to a body part, e.g. by use of an inflatable cuff. By performing repeated and alternating pressure changes in the cuff, a specific feature of a signal that relates to the diastolic blood pressure can be tracked and possibly measured. The device may have particular use in conjunction with cardiopulmonary resuscitation devices.

Abstract: A device (10, 10′, 10″) includes a light source (12) and a light detector (14) spaced from, and in communication with, the light source (12). An electronic processor (18) is programmed to compute pulse oximetry data from output of the light detector (14). A clamping member (26) is included, on or in which the light source (12) and the light detector (14) are disposed. The clamping member (26) is configured for attachment to a human body part with the body part disposed between the light source (12) and the light detector (14) such that light from the light source (12) passes through the body part to reach the light detector (14). The clamping member (26) is configured to attach to the body part by transitioning from a first stable state to a second stable state via a compression force applied to the clamping member (26).

Abstract: A switching mechanism is for enabling use of an inductive sensing circuit (16) in association with a portable handheld device (14) having electromagnetic transmission functionality in a manner that avoids harmful interference of the electromagnetic transmissions of the portable device with the subject when medical sensing is being performed. In particular, embodiments provide a controller (12) arranged to control switching between two modes: a first mode in which at least a portion of the transmission functionality of the portable device is deactivated and concurrently the inductive sensing circuit is activated; and a second mode in which the electromagnetic transmission functionality of the portable device is fully activated, and the inductive sensing circuit is deactivated. Thus embodiments provide a means of toggling between two modes, the modes configured to avoid simultaneous inductive sensing and full-power electromagnetic transmission of the portable handheld device.

Abstract: An inductive sensing system (8) is for detecting bleeding (e.g. blood pools) in one or more regions of the body. The system comprises a resonator circuit (10) having at least one antenna (12) which is driven with an oscillatory drive signal to cause generation of electromagnetic signals for application to a body. The signals induce eddy currents in the body which generate secondary EM signals returned from the body. These interact with the resonator circuit by adding an additional component of inductance to the circuit. This inductance component varies depending upon the conductivity of the fluid in which the eddy current is induced. Blood has a different conductivity to other body fluids. The system is configured to detect presence of abnormal accumulations of blood based on the additional inductance component. The system generates a data output representative of the determination.
