5 results about "Ventilator settings" patented technology

A test platform for simulating patient conditions. In accordance with methods, systems, platforms and modules, the controller of a ventilator, may be tested. Where the ventilator manages automated mechanical ventilation controllers' maintenance of peripheral oxygen saturation (SpO2) for a simulated patient, an analogue blood oxygen output signal that is responsive to the fraction of inspired oxygen (FiO2) and the peak inspiratory pressure ventilator settings of the ventilator is tested by a test platform controller. Where the ventilator manages end-tidal carbon dioxide (EtCO2) of a simulated patient, operation of the test platform controlled by the platform controller of the test platform in providing carbon dioxide generation, lung compliance (CL) and airway resistance (RAW) states while providing an EtCO2 level that is responsive to changes in tidal volume and respiratory rate changes of the patient is tested.

The utility model belongs to the technical field of medical instruments, particularly relates to a breathing machine, and aims to solve the problems that an existing breathing machine is inconvenient to carry and move, and a connecting pipe is easy to fall off due to dragging or pulling in the use process and needs to be fixed at a specific position, so that the movement range of a patient is limited, and the use cost is reduced. According to the technical scheme, the breathing apparatus comprises a telescopic frame and a breathing machine, a connecting base is fixedly arranged at the top of the telescopic frame, a mounting box is inserted into the connecting base, and the breathing machine is arranged in the mounting box and used for protecting the breathing machine; according to the breathing machine, the protectiveness and portability of the breathing machine are improved, the use requirements of different patients are met through the design of the flexible supporting assembly and the adjustable connecting piece, the comfort level and the use experience of the patients are improved, and meanwhile due to the stable fixing structure and the ergonomic design, the breathing machine is convenient to use. And the stability and the reliability of the equipment are further enhanced.

This invention proposes a patient adaptive respiratory regulation and control method and system based on isocarbonyl hyperventilation. It belongs to the field of medical device and intelligent control technology. The method includes: collecting real-time physiological parameters of the patient and ventilator settings to generate an initial physiological dataset; performing individualized dynamic estimation of key physiological parameters based on the initial physiological dataset to obtain real-time estimates of the patient's physiological dead space ventilation and carbon dioxide production rate; providing precise initial settings and main control quantities through feedforward prediction, fundamentally reducing the occurrence of large deviations; and combining intelligent feedback fine-tuning to quickly smooth out small disturbances, achieving a combination of "coarse adjustment" and "fine adjustment," making the stability and accuracy of PaCO₂ within the target range far exceed that of single feedback control.
