Problems solved by technology

[0003] Most of the current PEEP valve control of the ventilator is adjusted and controlled on a higher pressure constant pressure air source. However, the stability of the air source of the current ventilator is relatively poor. It is difficult to obtain accurate PEEP control pressure and control in this way. long cycle
Most of the supercharging devices under this control mode are used as constant voltage sources, which consumes a lot of power and reduces the actual efficiency of the supercharging device.

Embodiment Construction

[0056] figure 1 It is a hardware environment diagram of the application of the method for controlling the PEEP valve of the ventilator in an embodiment, and the pressure device 110 is a pressure source, which provides different control pressures. The large-flow compressed gas output by the pressure device 110 is throttled through the flow resistance 3, and then enters the input end of the proportional valve 140 after being safely controlled by the solenoid valve 130. The pressure provided by the proportional valve 140 and the pressure device 110 cooperate to form the required The control pressure of the PPEP valve 150. The pressure sensor 160 is used to detect the actual exhaled PPEP pressure when the user exhales through the breathing mask 190, the pressure sensor 170 detects the PPEP control pressure formed between the solenoid valve 130 and the proportional valve 140, and the control device of the ventilator PEEP valve is used to realize A method for controlling a PEEP val...

Abstract

The invention relates to a control method for a breathing machine PEEP valve. The control method comprises the steps of obtaining the current monitored PEEP pressure and the set PEEP pressure, judging whether the current monitored PEEP pressure is the same as the set PEEP pressure, returning to the step of obtaining the current monitored PEEP pressure and the set PEEP pressure if the current monitored PEEP pressure is the same as the set PEEP pressure, adjusting the supply pressure of a pressure device and the current of a proportional valve according to the current monitored PEEP pressure and the set PEEP pressure if the current monitored PEEP pressure is not the same as the set PEEP pressure and returning to the step of obtaining the current monitored PEEP pressure and the set PEEP pressure. The supply pressure of the pressure device and the current of the proportional valve are adjusted according to the current monitored PEEP pressure and the set PEEP pressured, the voltage of the pressure device can change along with the supply pressure of the pressure device, the pressure device needn't work in constant voltage, the actual using efficiency of the pressure device is improved, the supply pressure of the pressure device can be automatically adjusted, and the accurate PEEP pressure can be quickly obtained. In addition, the invention further provides a control device for the breathing machine PEEP valve.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a control method, device and system for a PEEP valve of a ventilator. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. The ventilator has a variety of ventilation methods, and PEEP (positive end expiratory pressure, positive end-expiratory pressure) is one of them. It maintains a certain pressure in the airway at the end of expiration under the premise of intermittent positive pressure ventilation. It plays an important role in the treatment of respiratory distress syndrome, non-cardiogenic pulmonary edema, and pulmonary hemorrhage. [0003] Most of the PEEP valve control of the current ventilator is adjusted and controlled on a higher pressure constant pressure air source...
