Wearable physical health testing systems and associated devices and methods are disclosed herein. A wearable system configured in accordance with embodiments of the present technology can include, for example, a communications hub, and a plurality of physical health testing devices. The communications hub and the plurality of physical health testing devices can integrated into an article of clothing, such as a jacket, a shirt, or a body suit. The physical health testing devices are in wired and/or wireless communication with the communications hub. Each physical health testing device is configured to generate physical health data of a user and to transmit generated physical health data to the communication hub and/or a user's mobile device. The wearable system provides an automated physical exam that can be performed at user's homes or other convenient locations.

An infrasonic stethoscope for monitoring physiological processes of a patient includes a microphone capable of detecting acoustic signals in the audible frequency bandwidth and in the infrasonic bandwidth (0.03 to 1000 Hertz), a body coupler attached to the body at a first opening in the microphone, a flexible tube attached to the body at a second opening in the microphone, and an earpiece attached to the flexible tube. The body coupler is capable of engagement with a patient to transmit sounds from the person, to the microphone and then to the earpiece.

Maxillary devices and Mandibular devices each have a first housing connectable to a tooth of a user or connectable or integral with a teeth covering, wherein the housing encloses an on-board circuit board and a power source. The first housing of the maxillary devices has a tooth connecting portion, a palate housing portion and/or a buccal housing portion. The first housing of the mandibular devices has a tooth connecting portion and a sublingual portion. Each of the palate housing portion and the buccal housing portion enclose a stimulator having an electrode electrically connected to the on-board circuit board and the power source, and can enclose a sensor and/or a medicament dispenser. The sublingual portion encloses a sensor and a medicament dispenser each of which are in electrical communication with the microprocessor of the on-board circuit board.

Embodiments described herein include sensors and sensor systems having probe-off detection features. For example, sensors and physiological monitors described herein include hardware and/or software capable of providing an indication of the integrity of the connection between the sensor and the patient. In various embodiments, the physiological monitor is configured to output an indication of a probe-off condition for an acoustic sensor (or other type of sensor). For example, in an embodiment, a signal from an acoustic sensor is compared with a signal from a second sensor to determine a probe-off condition.

A tubing assembly for electronic catheter guidance systems is provided and can include a catheter, an internal acoustic transducer and an external acoustic transducer. The catheter extends in a longitudinal direction and has proximal and distal ends that define a lumen therebetween. Further, the catheter is configured for placement within a patient's digestive or respiratory tract. The internal acoustic transducer can be located within the catheter's lumen, and the external acoustic transducer can be located on or outside the patient's body. The transducers can transmit and/or receive acoustic signals as directed by a processor and communicate with the processor to deliver sound data to a display device. The frequency response and/or attenuation of the signals can indicate placement of the catheter in the digestive tract compared to the respiratory tract. A catheter guidance system and method for accurately placing a catheter in the digestive or respiratory tract are also provided.

A stethoscope system may include an array of sensors, which may include pressure sensors. The array may be implemented in a wearable “patch” that is conformable to a patient's body. The stethoscope system may include a control system that is capable of receiving signals from the array of sensors. The signals may, for example, correspond to measurements from multiple pressure sensors of the array. The control system may be capable of combining signals from multiple pressure sensors to produce combined signals. The control system may be capable of filtering the combined signals to remove, at least in part, breathing signal components and to produce filtered signals. The control system may be capable of determining a correspondence between heart signal components of the filtered signals and corresponding heart valve activity.

An Integrated CardioRespiratory (ICR) System is provided for continuous Ejection Fraction (EF) measurement using a wearable device comprising a plurality of acoustic sensors. The ICR system performs signal processing computations to characterize cardiac acoustic signals that are generated by cardiac hemodynamic flow, cardiac valve, and tissue motion, and may use advanced machine learning methods to provide accurate computation of EF.

A method for assessment and/or monitoring a person's cardiovascular state comprises: using a sound and vibration transducer to acquire a vascular sound signal in order to detect a vascular sound from a cervical, thoracic, abdominal, pelvic, or lower limb region of the person; filtering the vascular sound signal to isolate the vascular sound, said filtering using a filter which attenuates frequencies below a lower cut-off frequency in a range of 100-300 Hz; and analyzing the filtered sound signal in order to determine whether an indication of a dicrotic notch in the vascular sound exceeds a set threshold.

The present invention provides a heart murmur detection device. The heart murmur detection device includes: an ECG signal detection unit for detecting an ECG signal from a heart of a user; a heart beat detection unit for detecting the frequency of the ECG signal; a plurality of sound receiving units for receiving a plurality of sound signals from the heart of the user; a signal transforming unit for transforming the sound signals into a plurality of electric phonic signals, and for retrieving the electric phonic signals on the basis of the ECG signal; and a signal processing unit for determining a heart murmur generating position. Moreover, the present invention further provides a heart murmur detection method.

The invention provides a body-worn patch sensor for simultaneously measuring a blood pressure (BP), pulse oximetry (SpO2), and other vital signs and hemodynamic parameters from a patient. The patch sensor features a sensing portion having a flexible housing that is worn entirely on the patient's chest and encloses a battery, wireless transmitter, and all the sensor's sensing and electronic components. It measures electrocardiogram (ECG), impedance plethysmogram (IPG), photoplethysmogram (PPG), and phonocardiogram (PCG) waveforms, and collectively processes these to determine the vital signs and hemodynamic parameters. The sensor that measures PPG waveforms also includes a heating element to increase perfusion of tissue on the chest.
