Description

Severe patient prone position ventilation unit

Technical Field

The utility model relates to a medical care apparatus field, concretely relates to severe patients prone position ventilation unit.

Background

Hypoxemia is the most common complication of severe pulmonary infection, mechanical ventilation is one of the main treatment measures, but severe pulmonary infection patients are often accompanied with atelectasis of prolapsed pulmonary part, and the pulmonary alveoli of the parts cannot be completely reopened simply by means of mechanical ventilation, but the pulmonary alveoli can be over-expanded and injured by pressure, and even the hemodynamics of the patients can be affected badly, so that the selection of posture drainage and pulmonary refolding strategies which can improve the oxygenation level and slightly affect the hemodynamics is very important for the treatment of severe pulmonary infection hypoxemia patients. The prone position can significantly improve oxygenation and reduce intrapulmonary bypass, and is more effective in correcting hypoxemia than the supine position for pulmonary atelectasis. The gradient of the pressure difference in the chest cavity is obviously reduced in the prone position compared with the gradient in the supine position, and the uneven distribution of gas in the lung is obviously improved, so that the quantity of alveoli which are changed on the back side in the prone position is greatly reduced, the quantity of alveoli with the refolding potential is increased, and meanwhile, the compliance of the chest wall is reduced, and the over-expansion of normal alveoli can be limited, so that a good refolding effect is achieved, and hypoxemia is improved. It has also been reported that pulmonary relaxation in prone position can reduce the consumption of pulmonary surfactant, reduce pulmonary edema, reduce the release of inflammatory mediators, and reduce the damage of lung endothelial cells by opening collapsed alveoli in sagging parts. In conclusion, the intermittent prone position ventilation of patients with severe pulmonary infection hypoxemia can effectively improve the oxygenation of the patients, has slight influence on hemodynamics, and is a safe and effective treatment strategy. Most patients needing prone position ventilation are provided with various pipelines, such as trachea cannula, thoracic drainage tube, deep vein catheterization tube, radial artery piezometer tube, stomach tube, urinary catheter and the like, and the pipelines need to be nursed by a special person during prone position ventilation and turning over so as to prevent the pipelines from being broken and separated; prevent the deep vein catheterization from being broken and separated, and ensure the continuous and effective pumping of various medicines. At present, the pitch position ventilation pad is mostly used for assisting a patient to perform pitch position treatment, but pressure sores are easily generated, the height of the patient cannot be adjusted according to limb characteristics of the patient in a sectional mode, and therefore the severe patient prone position ventilation device needs to be designed.
