The utility model belongs to the technical field of medical appliances, and particularly relates to a manual PEEP valve and breathing equipment.
Background
In the medical field, anesthesia ventilators are commonly used to assist a patient in respiratory ventilation when the patient is performing an operation or requires external assistance to breathe. However, after the patient exhales, the lung pressure of the patient rapidly drops to one atmosphere, so that the functional residual air in the lung of the patient rapidly decreases, the residual air in the lung of the patient is difficult to keep the alveoli to a certain volume, and meanwhile, the atrophy of the alveoli of the patient is likely to be caused due to the poor lung function of the patient; and the sharp drop in patient's pulmonary air pressure results in reduced compliance of the lungs, and poor ventilation and oxygenation status.
It would be desirable to provide a device that improves upon the above, and in particular, a PEEP valve (Positive End-Expiratory Pressure) that can be mounted directly to an external breathing device. When the PEEP valve is provided on a respiratory assistance device (such as an anesthesia respirator), the gas exhaled by a patient does not directly enter an external auxiliary respiratory device, but enters the external device through the PEEP valve (the PEEP valve has preset pressure suitable for the patient), so that the exhalation process of the patient is blocked, the lung pressure is not reduced to 1 atmosphere pressure value at the end of exhalation, and a certain amount of functional gas is remained in alveoli all the time, so that the lung maintains a certain pressure, thereby preventing alveoli atrophy, improving the compliance of the lung, improving the ventilation state and increasing the oxygenation time.
On this basis, the PEEP valve should also have an appropriate pressure regulation range to accommodate the needs of different patients. Along with the continuous progress of technology, some manufacturers have designed PEEP valves capable of manually adjusting pressure, but the existing PEEP valves have the problems of simple structure, poor stability and the like.
