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 invention belongs to the field of emergency medical rescue equipment technology and discloses an artificial respiration device for emergency clinical treatment, including a base, a connecting block, and a second support frame. The base has an internal adjustment structure, and the top of the second support frame has an emergency device. This invention uses a width adjustment structure composed of a bidirectional screw and connecting rod to adapt to patients of different body types; the compression seat can be replaced with different sizes, further improving adaptability to special populations such as children and obese patients, solving the problem of "fixed size and poor adaptability" of traditional devices; the locking structure of the lever and H-block, combined with the automatic spring return, can complete the deployment and locking of the support frame within 30 seconds; the width adjustment structure is driven by a motor, and can complete the precise adjustment of the patient support width in just one minute, fully meeting the core requirements of "rapid deployment and rapid rescue" in emergency scenarios; the anti-slip protrusions on the compression seat prevent slippage during compression, the diagonal brace enhances the structural stability of the device, and the limiting strip of the extension plate prevents sliding deviation. This multi-layered structural design effectively reduces safety hazards during rescue, improves the success rate of cardiopulmonary resuscitation, and is beneficial for practical application and operation.
