4 results about "Lung injury" patented technology

The present disclosure provides a unique solution for assisting in the ventilation of lungs of subject that is performed by artificial mechanical ventilator. The solution of the present invention improves the efficiency of the ventilation effect by applying desired pressure profile on portions of the upper body part of the subject in synchronization with the mechanical ventilator operation, thereby creating a desired pressure profile or gradient in the lungs airways to ensure that air pumped into the lungs by the mechanical ventilator spreads more homogeneously in the lungs than without the intervention of the system of the present invention. The application of pressure is determined after analyzing data from sensors of the system that are placed on a plurality of portions on the upper body part of the subject and data received from the mechanical ventilator. These sensors sense data indicative of the ventilation profile within the lungs, i.e. pressure profile along different portions of the lung. The system provides extra-thoracic pressure on the rib cage according to pre-defined and adaptive algorithms based on the physiological status, the respiratory mechanics, and the inhomogeneous nature of lung injury. By applying pressure to the hyperventilated areas and reducing the transpulmonary pressure gradient, the system prevents hyperinflation trauma to the open areas and atelecto-trauma to the closed areas. The system is synchronized with the mechanical ventilator and adapt to changes in the patient's respiratory mechanics.

This application relates to the use of dexmedetomidine in the preparation of a drug for protecting the glycocalyx structure of lung tissue, a formulation thereof, and its application, belonging to the field of lung injury technology. This application provides a formulation for protecting the glycocalyx structure of lung tissue, the formulation containing dexmedetomidine, which can protect the glycocalyx structure of lung tissue, thereby reducing lung injury and can be used to treat lung injury.

This invention provides a lung-moistening lotion and its application in the preparation of products for preventing lung injury caused by environmental pollutants. The invention uses loquat leaf extract and bamboo culm extract as active ingredients, employing a low-temperature treatment and mild water extraction process, and compounding them in a specific ratio. The synergistic effect of these two ingredients significantly reduces intracellular reactive oxygen species levels, restores antioxidant defense capabilities, inhibits abnormal expression of inflammatory factors, and improves lung function-related indicators. The product of this invention has high safety, is suitable for long-term consumption, and can be used to prepare functional foods, health foods, or respiratory care products. It also shows promising application prospects in the prevention of lung injury related to nanoplastics.
