70 results about "Respiratory sounds" patented technology

A method and apparatus for estimating a respiratory rate of a patient. The method comprises the steps of recording respiratory sounds of the patient, deriving a plurality of respiratory rates from the recorded sounds using a plurality of respiratory rate estimating methods and applying a heuristic to the plurality of derived respiratory rates, the heuristic selecting one of the derived respiratory rates. The selected respiratory rate is the estimated respiratory rate. The apparatus comprises at least one sensor recording respiratory sounds of the patient, a plurality of respiratory rate processors, each of the processors comprising a respiratory rate calculating method, a heuristic means for selecting one of the calculated respiratory rates and a display means for displaying the selected respiratory as the estimated respiratory rate.

A method of analyzing breath sounds produced by a respiratory system, the method comprising: measuring breath sounds produced by the respiratory system; tentatively identifying a signal as being caused by a breath sound of a given type if it meets a first criteria characteristic of the breath sound of the given type; and confirming said identification if a tentatively identified signal meets a second criteria characteristic of the breath sound of the given type.

Provided is a device for attachment to the head of a horse to enable recording of respiratory sounds in the intensely exercising animal, e.g., in a breezing Thoroughbred racehorse. Also provided are methods for predicting racing performance in a horse, e.g., a Thoroughbred race horse, comprising measuring expiratory and / or inspiratory times for a subject horse during exercise and relating such information to anatomy, front leg stance times and / or front leg stance distances and / or to speed (velocity) to determine the animal's potential to sustain a superior rate of ground coverage for a desired amount of time and identify a maximum comfortable velocity for the animal. A presently preferred embodiment of the methods of the invention comprises predicting performance via identification of expiratory time determined directly from the analysis of recorded respiratory sound from the exercising animal.

The invention relates to a lung lobe breath sound monitoring and automatic analyzing device which comprises a breath sound signal collecting system, a power supply management module, a breath sound input module, a filter module, an audio power amplifier, a waveform conversion module, a loudspeaker, a CPU processor, a touch screen and an LCD display, wherein the power supply management module is connected with the input end of the breath sound input module by virtue of a wire; the output end of the breath sound input module is connected with the filter module by virtue of a wire; the output end of the filter module is connected with the input ends of the audio power amplifier and the waveform conversion module by virtue of wires; the output ends of the audio power amplifier and the waveform conversion module are connected with the CPU processor; the CPU processor is connected with the touch screen and the LCD display by virtue of wires; and the audio power amplifier is connected with the loudspeaker by virtue of a wire. The device provided by the invention is of non-invasive measurement. Compared with common stethoscopes, the device can capture weak breath sound changes sensitively and objectively, can be used for precisely and dynamically analyzing the result for lung lobe breath sounds and not only is time-saving and labor-saving, but also can reduce the number of times of radiographic inspection on the chest of the patient.

The present invention provides a method for managing a patient having a sleep disorder, e.g. sleep apnea, snoring, sleep bruxism, upper airway resistance syndrome, etc. The method comprises monitoring physiological information from the patient, converting the physiological information to digital data, storing the digital data in a digital memory, identifying and characterizing epochs based on the digital data, and storing the identifying and characterizing information of the epochs in a digital memory. The method further comprises organizing the epochs according to an organization function that considers at least characterization information of the epochs, selecting an epoch based on the organizing of the epochs, and generating sound derived from the stored digital data associated with the selected epoch such that the patient hears the sound. In a specific embodiment, the physiological information monitored may include sound, e.g. respiratory sound emanating from the trachea, and / or tooth-grinding sounds.

The present invention provides a bed set for inhibition of obstructive sleep apnea, which includes: a sound receiving module, is used to receive a respiratory sound signal obtained from a user during a time period; a sound analyzing processor, which is connected with the sound receiving module, is used to obtain a snoring sound characteristic from the spectrum of respiratory sound signal; a database, which has a plurality of snoring image characteristics corresponding to a plurality of basic snoring sound characteristics for different respiratory actions; a control processor, which is connected with the sound analyzing processor and the database, is used to compare the snoring sound characteristic with the basic snoring sound characteristics to select one of the snoring image characteristics in the same waveform, and provides the first angle control order and the second angle control order corresponding to the selecting snoring image characteristic; a first pillow, which is connected to the control processor, declines a first angle toward a declination direction after receiving the first control order; and a second pillow, which is connected to the control processor, declines a second angle toward the declination direction after receiving the second control order.
