A device for determining a precise placement of a medical sensor on a patient's chest is provided, the device comprising: a vertical portion including a sternal notice index portion for alignment with the patient's sternal notch, wherein the sternal notch index portion extends along a portion of the patient's sternum, wherein the vertical portion includes vertical patient size indices; and an arm extending from the vertical portion across the patient's midclavicular line, wherein the arm is oriented at a right angle to the vertical portion, wherein the arm includes horizontal patient size indices.

Disclosed herein are methods and systems for identifying a position of a plurality of electrodes in an EEG electrode array embedded to an EEG electrode array carrier when the EEG electrode array carrier is worn on a head of a subject. A first system is an optical system containing a stereo camera pair which captures at least one image of the head of the subject wearing the EEG electrode array carrier. A second system is an electrical system which constructs a 3D electrical model of the EEG electrode array and an electrical model of a couplant spreading of the couplant which couples the electrodes to the head of the subject. The two systems may be integrated to one electro-optical system for identifying a position of electrodes in an EEG electrode array on a head of a subject.

A capsule (220), said capsule (220) having a coupling face (222) configured to be coupled to a complementary shape on a housing (120), and a microneedle array (210) that is positioned on a planar contact surface (229). The coupling face (222) has rotational symmetry about an axis of rotation (Z) which extends orthogonally to the planar surface (229) and about which at least two coupling positions are permitted with a single and unique complementary shape on a housing (120), there being, within a fixed reference frame, no microneedle (210) in the same location as that of a different microneedle (210), in the two positions.

A system for monitoring a joint of a user includes: a goniometer device for measuring an angle of the joint, and a pedometer removably attached to the goniometer device and configured to count a number of steps taken by the user. The goniometer device includes: a center hub, a first arm attached to the center hub, and a second arm attached to the center hub. A pedometer device for detecting steps taken by a user includes: a body and a circuit board including one or more sensors for detecting motion. The body is configured to be removably attached to a peripheral device by a magnetic coupling.

A system for measuring an angle of a joint of a user includes a coupling apparatus configured to be adhesively attached to a limb portion proximal to the joint of the user, and a goniometer device. The goniometer device includes: a center hub, a first arm having a first inner end attached to the center hub and a first outer end opposite the first inner end, and a second arm having a second inner end attached to the center hub and a second outer end opposite the second inner end. The first outer end of the first arm is removably attachable to the coupling apparatus by a magnetic attachment.

A noninvasive blood pressure monitor. The noninvasive blood pressure monitor may include an inflatable cuff, a pressure transducer, one or more air pumps, and a processor. The processor may control the air pump(s) so as to initiate inflation of the cuff. The processor may also identify an oscillometric signal in an output of the pressure transducer, and may determine an envelope of the oscillometric signal. The processor may also determine one or more characteristics of the envelope of the oscillometric signal, and may control the air pump(s) so as to stop inflation of the cuff based on the one or more characteristics of the envelope of the oscillometric signal.

The present invention relates to methods for marking positions for or for positioning of six ECG chest electrodes based on a subjects body height, which allows a reproducible placement of the electrodes in serial independent ECG measurements. The present invention further relates to a device for placement of ECG electrodes which implements said method, and methods and uses applying said device. Hence, the present invention provides an accurate and reproducible, easy to use and low-cost method and device for ECG chest electrode positioning, especially in serial examinations and in obese subjects by minimizing the mistakes in ECG chest electrode placement depending on the subjective and inaccurate defining of anatomic remarks for electrode positions.
