A sound detection system includes a plurality of microphones each configured to detect a sound inside a living body and output a sound signal generated based on the detected sound; and an information processing device that includes an acquisition unit configured to acquire the sound signal from each of the plurality of microphones, a control unit, and an output unit, the control unit specifies a first position that is a position of a prescribed living body site based on the sound signals acquired by the acquisition unit, estimates a second position that is in a prescribed relative positional relation with the first position, and controls directivities of the plurality of microphones to increase a sensitivity with respect to the second position, and the output unit outputs information generated based on the sound signals acquired by the acquisition unit in which the directivities of the plurality of microphones are controlled.

This document describes a system for determining positioning of an intubation tube in a patient. The system can include a first acoustic sensor configured to be disposed to listen to one of a lung and a stomach of the patient and to provide a first signal. The system includes a signal processing unit, coupled to the first acoustic sensor, configured to analyze spectral components of the first signal and determine whether a frequency of the spectral components of the first signal are characteristic of sounds induced by ventilation via the intubation tube of airflow to the lung or the stomach of the patient.

A metallic diaphragm disk incorporating a piezoelectric material bonded thereto and operatively coupled to a base rim of a housing provides for closing an open-ended cavity at the first end of the housing. At least one inertial mass is either incorporated in or attached to the housing. A plastic film adhesively bonded to at least one of an outer rim of the housing or an outer-facing surface of the disk provides for receiving an adhesive acoustic interface material to provide for coupling the housing to the skin of a test subject.

A method for medical diagnosis includes recording voice signals due to sounds spoken by a patient and recording acoustic signals output, simultaneously with the voice signals, by an acoustic transducer in contact with a thorax of the patient. A transfer function is computed between the recorded voice signals and the recorded acoustic signals or between the recorded acoustic signals and the recorded voice signals. The computed transfer function is evaluated in order to assess a medical condition of the patient.

The present disclosure provides an apparatus comprising a housing with a left side panel, right side panel, and top panel, each of which may comprise a slot. The apparatus may comprise a front panel that is insertable into the slots of the left and right-side panels. The front panel may comprise a recessed region configured to receive a portion of a medical instrument. A source of a barrier material may be supported by the left and right-side panels. The apparatus may comprise a lid cover comprising a roller portion that is insertable into a slot of the top panel. The lid cover may pivot relative to the housing when the roller portion is inserted into the slot of the top panel. The lid cover and the front panel may form a gap through which a portion of the barrier material may extend when the barrier material is dispensed.

The present invention relates to a method and system for determining a central pulse wave velocity in a pregnant woman. The method comprises receiving an indication of a measurement of a length of a human aortic path outside the body to provide an aortic length, arranging a sound transducer at the position of the anatomical projection of the uterine artery, identifying the opening of the maternal aortic valve with measurement from the sound transducer as a first time, and the pulse wave arrival time at the uterine artery with measurements from the sound transducer as a second time, determining the central transit time based on the difference between the second time and the first time, and calculating the central pulse wave velocity based on the aortic length and the central transit time.

Apparatus and methods for applying a barrier to a medical scope are provided. An apparatus may comprise a source of film and a housing. The housing may comprise a chamber configured to support therein the source of film, and an opening provided through a wall of the housing to permit a portion of the film to extend out of the chamber when the film is dispensed. The housing may comprise a recess located such that the extended portion of the film is permitted to hang freely in proximity to the recess. The recess may be sized to receive a distal portion of the medical scope. The recess may be adapted to allow the extended portion of the film to be applied to the distal portion of the medical scope when the distal portion is placed into the recess with the portion of the film located therebetween.

An electronic stethoscope includes an acoustic sensor assembly having a first microphone to detect biological sounds within a body, a detection system in communication with the first microphone to receive an auscultation signal from the first microphone, the auscultation signal including information of the biological sounds detected by the first microphone. The stethoscope also includes a second microphone in communication with the detection system to detect noise from an environment of the body. The detection system receives a noise signal from the second microphone, and provides a resultant signal based on the auscultation signal and the noise signal. The detection system subtracts information from the auscultation signal to produce the resultant signal, where the subtracted information is based on the noise signal such that the subtracted information is based more on higher frequency ranges of the noise signal compared to a lower frequency range corresponding to the biological sounds.

A garment comprising a central portion including a plurality of electrocardiogram leads, a plurality of auscultation acoustic sensor devices, a flexible respiratory sensor located so that it substantially circumscribes the garment, one or more blood pressure cuff portions located on an at least one arm portion of the garment, wherein the cuff portions are adapted to be loosened and/or tightened and a hardware device for sending and receiving signals via wired or wireless communication.
