5 results about "Respiratory rate" patented technology

The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

The invention discloses a method for dynamically determining breathing oxygen consumption and a hypoxia device for the method for dynamically determining the breathing oxygen consumption. The method includes the following steps that after distilled water is added from an air vent and reaches a weather bar, a tee valve is closed, a mouse is contained in a hypoxia bottle where soda lime is placed in advance, and then a bottle plug is fastened; when the hypoxia bottle generates 0.5cmH2O negative pressure, water flows in an oxygen consumption determining channel enable the pressure to be -0.5cmH2O constantly, and the amount of consumed oxygen is read out; a high-sensitivity tension transducer is used for automatically monitoring the breathing rate, the breathing range and breathing pressure of the laboratory mouse with oxygen deficiency; when a repeated experiment is performed, air in the oxygen consumption determining channel is exhausted and then the operations are repeated; the hypoxia device established according to the determining method comprises a device body, the hypoxia bottle and a biological signal collecting and processing system. The method for dynamically determining the breathing oxygen consumption and the hypoxia device for the method for dynamically determining the breathing oxygen consumption have the advantages that the pressure is constant, due to the fact that the breathing rate, the breathing range, the amount of the consumed oxygen and the pressure value of the hypoxia environment of the mouse with hypoxia are monitored dynamically, errors caused by manual monitoring are avoided, and the method and the hypoxia device are suitable for determination of the consumed oxygen amount and a hypoxia experiment.

The invention discloses a first-aid classification and injury detection system comprising an injury detection and classification handheld module, a heart rate and respiratory rate detection module, ahand-held rapid temperature measurement module and a blood pressure detection module. With small discrete and portable and easy-to-use modes, quick detection of an electrocardio signal, a respiratorysignal, a blood pressure signal and a body temperature signal, wireless transmission, and automatic data recording and other functions are realized. The system has voice recognition and voiceprint recognition functions; semantic recognition and automatic recording can be carried out on physiological indicators, read by ambulance men, of injured people on special occasions. An intelligent automaticinjury classification and detection program is arranged in the injury detection and classification handheld module to realize functions of intelligent auxiliary diagnosis and injury level scoring ofinjured people and the like; and the injury states can be evaluated quickly and automatically. The respiratory signal is detected by the impedance method; and the sensing mode is simple and is easy tooperate. The system has shockproof, waterproof and anti-dust functions and can be applied in various extremely severe environments; and the ear temperature or body surface temperature can be measuredquickly.

Herein we describe a nasal inspiratory resistance trainer (“NIRT”) that increases the difficulty of nasal breathing. The device is specially designed to limit the cross-sectional area of the nostril, which decreases the volume of air a person can easily intake per unit time, typically achieved by reducing tidal volume per breath, reducing respiratory rate, or a combination thereof. Specific implementations are described.
