Problems solved by technology

The problem with this method is that the control pressure rises linearly. When the slope time is set longer, it takes longer to reach the target value. This makes it impossible for the patient to quickly obtain the ideal ventilatio

Abstract

The embodiments of the present invention disclose a pressure control method in a respirator. The pressure control method comprises the following steps: a set pressure rise period is acquired; a presetpressure control function is acquired, the pressure rising period is parameters of the pressure control function, and the pressure control function comprises a sine function or a cosine function; a pressure control proportion corresponding to current rise time is determined according to the pressure rise period and the pressure control function; a target pressure value is acquired; a current pressure value corresponding to the current rise time of the respirator is determined according to the target pressure value and a pressure control proportion corresponding to the current rise time; pressure of the respirator is controlled according to the current pressure value to realize accurate control of the pressure of the respirator, full air exchange of bubbles in the lungs of a patient and fresh air is facilitated, an overshoot phenomenon of the pressure control in a ventilation process of the respirator is also eliminated, and a ventilation effect of the respirator is greatly improved. In addition, the present invention also provides a pressure control device in the respirator, the respirator and a storage medium.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pressure control method and device in a ventilator, a ventilator and a storage medium. Background technique [0002] In the PCV mode of ventilator pressure control ventilation, the initial pressure rise phase (ie, the slope phase) is an important performance index in the PCV ventilation mode, which reflects that the target pressure can be quickly reached within the set time during the ventilation process. By adjusting the slope time, the speed of reaching the target pressure value can be controlled. Then, in the current PCV control method, the target pressure is mainly calculated by using a linear slope within the specified rising time to input the target pressure at each moment to the control unit for pressure control to finally achieve the effect of the target set pressure. The problem with this method is that the control pressure rises linearly. When the slope tim...
