The invention is applied to the technical field of disease diagnosis, and discloses a respiratory gas analysis-based disease diagnostic apparatus, which comprises a functional box, a first gas inlet joint is fixedly arranged on the outer surface of one side of the lower end of the functional box, and one end of the first gas inlet joint is fixedly connected with one end of a first gas inlet hose; the other end of the first air inlet hose is fixedly connected with an air blowing cylinder, a display screen is fixedly installed on the upper surface of the functional box, a dynamic detection mechanism is arranged in the functional box, and the overall working efficiency of the diagnostic apparatus is improved by collecting and temporarily storing breathing gas. According to the disease diagnostic apparatus based on respiratory gas analysis, the central motor drives the central seat to rotate, the gas storage tanks uniformly distributed on the central seat can sequentially collect and temporarily store respiratory gas, and in the rotating process of the central seat, the gas in the different gas storage tanks can be continuously conveyed to the gas detection module for detection; and the defect that a small amount of gas samples are detected once by traditional equipment is avoided.

In a method for operating a respiratory gas analysis device with at least one gas sensor, once a respiratory gas analysis has been carried out, the gas sensor is heated to a temperature that lies above a predefinable temperature threshold value.

Systems and methods have been developed for implementation of a breath testing system for convenient sampling of intestinal gases exhaled from a patient's breath. This may include a system with a manifold that includes thermal regulation components, for instance thermistors and resistive heating elements, which maintain the temperature of the gases above the body temperature of the patient. In some examples, the system will determine an indication of whether a patient has SIBO by adjusting a change in exhaled hydrogen concentration by a methane level exhaled by a patient.

This invention relates to the field of disease diagnosis technology and discloses a disease diagnostic instrument based on respiratory gas analysis. The instrument includes a functional box. A first air inlet connector is fixedly mounted on the lower outer surface of the functional box, with one end of the first air inlet connector fixedly connected to one end of a first air inlet hose, and the other end of the first air inlet hose fixedly connected to an air blowing tube. A display screen is fixedly mounted on the upper surface of the functional box. A dynamic detection mechanism is installed inside the functional box to accelerate the overall working efficiency of the diagnostic instrument by collecting and temporarily storing respiratory gases. This disease diagnostic instrument based on respiratory gas analysis uses a central motor to drive a central base to rotate. Evenly distributed gas storage tanks on the central base can sequentially collect and temporarily store respiratory gases. During the rotation of the central base, gases from different storage tanks can be continuously delivered to the gas detection module for detection, avoiding the drawback of traditional equipment that can only detect small amounts of gas samples at a time.

The invention discloses an intelligent remote ischemia monitoring system based on multi-sensor fusion, relates to the technical field of intelligent detection, and is used for solving the problem of limitation of monitoring of a single sensor. Comprising a data acquisition module, a region division module, a data fusion and ischemia detection module, a data storage module and a remote monitoring and data transmission module, all the modules are in signal connection, and the region division module is combined with a respiratory gas analysis technology to obtain spatial positions, pathological states and metabolic rate data of physiological organs; dividing a detected area into a plurality of sub-areas, and optimizing sensor arrangement; the data fusion and ischemia monitoring module is combined with a weighted summation method, fusion processing of different physiological parameter data is completed, and evidences of a plurality of sensors are synthesized according to the DS evidence theory. And finally, the remote monitoring and data transmission module performs data transmission through an MQTT protocol. And displaying the physiological data of the patient by using a Web platform.
