Abstract

The invention provides an airway control device for a medical breathing apparatus, which comprises a pressure relief valve, a pressure sensor, an electromagnetic valve, a safety valve, a pressure regulating valve (PEEP (Positive End Expiratory Pressure) valve) and a first air resistor, wherein the inlet port of the pressure relief valve is connected with a gas source; the inlet port of the pressure sensor is connected with the outlet port of the pressure relief valve; the inlet port of the electromagnetic valve is connected with the outlet port of the pressure relief valve; the electromagnetic valve is controlled by the pressure sensor; the inlet port of the safety valve is connected with the outlet port of the electromagnetic valve; the inlet port of the PEEP valve is connected with the outlet port of the electromagnetic valve; the inlet port of the first air resistor R1 is connected with the outlet port of the electromagnetic valve; and the outlet port of the first air resistor R1 is respectively connected with the inlet port of the safety valve and the inlet port of the PEEP valve. The invention has the advantages of simple structure, low cost and high control sensitivity, and can ensure the safety of the user under various abnormal conditions.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an airway control device for medical ventilation equipment. Background technique [0002] During the use of medical devices such as ventilators and anesthesia machines, patients need to be mechanically ventilated. For patients who are being treated, it is very important to control the amount of ventilation, especially for infants and critically ill patients. This requires not only precise flow control, but also the sensitivity of the safety valve to changes in airway pressure and air source pressure. It is required that the safety valve can be well sealed under the safety pressure of the airway, and it can be opened quickly and accurately when the airway pressure exceeds the upper pressure limit and is lower than the lower pressure limit. Therefore, the control of the safety valve is crucial to the accuracy and safety of medical devices such as ventilators and anesthesia machines....
