A charging station for providing power to a physiological monitoring device can include a charging bay and a tray. The charging bay can include a charging port configured to receive power from a power source. The tray can be positioned within and movably mounted relative to the charging bay. The tray can be further configured to secure the physiological monitoring device and move between a first position and a second position. In the first position, the tray can be spaced away from the charging port, and, in the second position, the tray can be positioned proximate the charging port, thereby allowing the physiological monitoring device to electrically connect to the charging port.

Monitoring vital parameters of a wearer of a compression garment by analyzing a pressure signal waveform indicative of a fluid pressure in an inflatable and deflatable bladder of the compression garment. Analyzing the pressure signal waveform for an oscillating amplitude as a function of time and/or a representation of a pulse of the wearer provides an indication of blood pressure of the wearer.

An assembly for enabling a caregiver to secure a physiological monitoring device to an arm of a user can include the physiological monitoring device a cradle configured to removably secure to the physiological monitoring device and to the user's arm. The physiological monitoring device can include a first connector port configured to electrically connect to a first cable and a first locking tab movable between an extended position and a retracted position. The cradle can include a base, first and second sidewalls, a back wall connected to the base and the first and second sidewalls. The cradle can further include a first opening in the back wall configured to receive the first connector port and a second opening in the first sidewall configured to receive the first locking tab when the physiological monitoring device is secured to the cradle and the first locking tab is in the extended position.

A blood pressure measurement device may include one or more piezoelectric sensors (e.g., differential piezoelectric sensors) for detecting blood flow through a limb of a user as part of determining blood pressure measurements. The piezoelectric sensor(s) may additionally or alternatively be used to determine one or more biological parameters of users (e.g., a ballistocardiogram, a heart rate, a heart rate variability, and a pulse wave velocity). The blood pressure measurement device may additionally or alternatively include a capacitive sensor for determining a pressure applied to the limb of the user by the blood pressure measurement device and/or operational states of the blood pressure measurement devices (off-arm, on-arm, inflating, deflating, tightness, and the like).

A blood pressure cuff may comprise an alignment component, a sleeve, and a tapered inflatable bladder disposed within the sleeve. The tapered inflatable bladder may have a width that increases as the distance from the alignment component increases, and the tapered inflatable bladder and the alignment component may be configured to position the blood pressure cuff around a limb having a blood vessel and a circumference, such that at a position coincident with the blood vessel, the width of the tapered inflatable bladder is about 40% of the circumference of the limb. A method of using such a blood pressure cuff may comprise placing the alignment component at the position coincident with the blood vessel of the limb, wrapping the cuff around the limb such that the width of the tapered inflatable bladder overlaying the blood vessel is about 40% of the circumference of the limb, and inflating the bladder.

Systems and methods for electronically monitoring chest sounds and/or sensing electrical cardiac signals such as ECG signals are provided. In one embodiment, a hybrid stethdiographer has a sensing assembly with a chestpiece and a user interface. Stethdiographer also includes a conduit, a power source compartment, a pair of binaurals and a corresponding pair of earpieces. The user interface includes a record button, a mode selector and a display screen. The chestpiece includes a diaphragm and a plurality of electrical cardiac sensors.

A wearable device configured to measure one or more physiological parameters of a user is described. In some embodiments, the wearable device includes: a top frame, a bottom frame connected to the top frame, and an interior between the top and bottom frames; a circuit board positioned within the interior; a first temperature sensor coupled to the circuit board and configured to generate one or more signals responsive to thermal energy of the user; and a second temperature sensor coupled to the circuit board and configured to generate one or more signals responsive to at least one of temperature within said interior and temperature outside said interior. In some embodiments, the circuit board is positioned between the first and second temperature sensors and no air gap is present between either of the first and second temperatures and the circuit board.

Non-invasive methods for accurately classifying Coronary Artery Disease (CAD) is a challenging task. In the present disclosure, a two stage classification is performed. In the first stage of classification, a metadata based rule engine is utilized to classify a subject into one of a confirmed CAD subject, a CAD subject and a non-CAD subject. Here, a set of optimal parameters are selected from a set of metadata associated with the subject based on a difference in frequency of occurrence of the CAD among a disease population and a non-disease population. Further, an optimal threshold associated with each optimal parameter is calculated based on an inflexion based correlation analysis. Further, the CAD subject, classified by the metadata based rule engine is further reclassified in a second stage by utilizing a set of cardiovascular signal into one of the CAD subject and the non-CAD subject.
