The embodiment of the application provides a kind of respiratory detection equipment, including shell, first gas path and second gas path are in shell, the two ends of first gas path are respectively communicated with the air inlet and air outlet on shell, second gas path is communicated with first gas path, first gas detection module is arranged in first gas path to detect the gas volume of gas, second gas path is communicated with second gas detection module, to detect the content of component gas contained in gas.It also includes adjusting piece, adjusting piece is in first position, the shielding part of adjusting piece shields air outlet, the gas exhaled by user can be introduced into second gas detection module, to realize the function of component gas content detection in exhaled gas.Adjusting piece is in second position, the first through opening part of adjusting piece is communicated with air outlet, and the exhaled gas can be discharged from air outlet, to realize the function of vital capacity detection, enrich the function of respiratory detection equipment, it is conducive to realizing multifunctional integration, satisfy the demand of respiratory system function detection at home.

This invention relates to the field of respiratory care technology and discloses a pre-operative respiratory function trainer for respiratory endoscopy, comprising a base and a mouthpiece. A mounting base is fixedly connected to the top of the base, and an air cylinder is fixedly connected to the top of the mounting base. A float is disposed within the inner cavity of the air cylinder, and a training component is disposed within the inner cavity of the mounting base. This invention integrates respiratory training, air filtration, real-time monitoring, and data display functions into a compact structure, specifically designed for patients before respiratory endoscopy. It effectively trains the patient's respiratory muscle strength and vital capacity. Through the monitoring component, particularly the pressure sensor and pressure value display screen, the patient's blowing force can be converted into specific numerical values ​​in real time and displayed, making the training effect measurable and recordable. Simultaneously, the range scale on the surface of the air cylinder and the rising height of the float provide the user with direct visual feedback, helping to maintain and enhance training motivation.

A combined or convertible handheld unit that combines a personal spirometer, exhalation-analysis or breath-analysis function with a nebulizer or vaporizing function. The nebulizer or vaporizing function includes, but is not limited to, functions provided by devices such as inhalers, nebulizers, vaporizers, humidifiers, ventilators, or other devices that are used for delivery of any sort of substance into the body via breathing, and includes but is not limited to devices that break up solutions and suspensions into small aerosol droplets for inhalation by a user. The unit also performs full exhalation detection and analytics.

Methods of treating of interstitial lung disease, reducing pulmonary function decline in a subject with interstitial lung disease (ILD), and increasing forced vital capacity (FVC) in a subject suffering from ILD are provided, wherein the methods include administration of treprostinil.

A breathing monitor has ECG, PPG, or bioimpedance sensors feeding a neural network to provide inspiratory and expiratory phases of breathing and tidal volume (TV), filters for the inspiratory and expiratory phases of breathing and TV; and apparatus configured to provide measurements of breathing rate (RR), and fractional inspiratory time (FIT). In embodiments, the device uses the RR, FIT, and TV to estimate spirometric parameters such as lung obstruction severity, forced expiratory volume in one second (FEV1), forced expiratory volume (FEV), forced vital capacity (FVC), FEV1 / FEV ratio, and FEV1 / FVC ratio. A method of determining a classification of lung obstruction from heart signals includes feeding heart signals into a neural network to determine TV and inspiratory and expiratory classes used to determine FIT and RR; and using FIT, RR, and TV to determine lung obstruction classification of mild, moderate, severe, or very severe obstructive symptoms.
