This invention relates to the field of medical data processing technology, specifically to a lung infection status early warning system based on medical big data. The system captures the flow velocity response before and after expiratory pressure regulation, and uses regularized inversion to deconstruct the time-domain signal, which is disturbed by respiratory rate, into a standardized sequence of measured lung unit volumes. Subsequently, it constructs a theoretical distribution benchmark of purely elastic recoil using measured high-pressure data. By constructing a transmission cost matrix reflecting the shear characteristics of non-Newtonian fluids, it uses an optimal transmission algorithm to calculate the optimal transmission strategy that reshapes the theoretical distribution into the measured distribution. Finally, it analyzes the topological entropy and transmission energy consumption of this transmission strategy to extract obstruction features and generate an early warning. This invention utilizes a rheological model to specifically quantify the viscosity and focal distribution of fluid within the airway, effectively differentiating between physical pulmonary edema and biological airway obstruction at an early stage.

This invention discloses a simple emergency airway obstruction clearing device, relating to the technical field of airway drainage. It includes a piston cylinder with a first and second movable chamber. An air supply tube is fixedly connected to the outside of the piston cylinder, communicating with the first movable chamber and a face mask. A piston rod is slidably connected within the first movable chamber, and a sliding frame is slidably connected within the second movable chamber. A rubber ring is fixedly connected to one end of the sliding frame, and a spring is fixedly connected to the other end. This invention, through the design of a bellows and pull rod mechanism, ensures that the negative pressure in the first movable chamber compresses the bellows only when the face mask is tightly fitted to the patient's face, forming an effective seal. This triggers the latch release action, releasing the spring's stored energy. This design avoids ineffective operation due to poor sealing, ensuring that each trigger is based on effective negative pressure, thus improving the reliability of emergency treatment.
