Abstract

The invention relates to a positive end expiratory pressure (PEEP) safety protection system and a method thereof. The system comprises a breathing machine, a PEEP valve, a proportional solenoid, a safety solenoid, a PEEP pressure collection unit and a processor, wherein the proportional solenoid and the safety solenoid are arranged on a controlling air passage of the PEEP valve; the method comprises the following steps: detecting the PEEP pressure by utilizing a pressure sensor; opening the safety solenoid if the PEEP pressure is within a normal range, and conducting the connection between the pneumatic control end of the PEEP valve and an air source; and closing the safety solenoid if the PEEP pressure exceeds the highest threshold, and cutting off the connection between the pneumatic control end of the PEEP valve and the air source. According to the safety protection system and the method thereof, the control is accurate, and the positive end expiratory pressure is continuous and adjustable; and moreover, the loss of the air source can be reduced.

Description

technical field [0001] The invention relates to medical electronics, in particular to a positive end-expiratory pressure (PEEP) safety protection device applied in a ventilator system. Background technique [0002] PEEP is positive end-expiratory pressure. When the airway is opened at the end of expiration, the airway pressure remains higher than atmospheric pressure to prevent alveolar atrophy and collapse. When PEEP is abnormally increased, the work required for exhalation increases, causing difficulty in exhaling, which may lead to increased risk of suffocation and increased work of breathing. At present, the mechanical positive end-expiratory pressure control method used by the ventilator cannot accurately control the end-expiratory pressure and the positive end-expiratory pressure cannot be continuously adjusted. The safety factor is insufficient and the gas consumption is high. Contents of the invention [0003] The technical problem to be solved in the present inve...
