Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0029] figure 1 The gas circuit structure of the positive end-expiratory pressure control system of the ventilator of the present invention is shown.

[0030] see figure 1 As shown, the positive end-expiratory pressure control system of the ventilator includes:

[0031] The PEEP execution part is connected to the electronic PEEP part of the patient's breathing circuit to realize the PEEP function; the PEEP execution part includes: an output interface and a PEEP valve respectively connected to the output interface, an electronic PEEP control part, a ventilator and a patient breathing apparatus. pipeline.

[0032] The electronic PEEP control part is connected to the PEEP control port of the breathing valve. The electronic PEEP control part controls the path of the proportional solenoid valve by adjusting the current of the proportional solenoid valve, so that the...

Abstract

The invention relates to a breathing machine positive end-expiratory pressure control system, circuit and a control method thereof. The control method comprises a PEEP (Positive End Expiratory Pressure) execution part and an electronic PEEP control part, wherein the PEEP execution part is connected with an electronic PEEP part patient respiration pipeline; the electronic PEEP control part is connected with a respiration valve PEEP control port; the drift diameter of the control port can be controlled by regulating the current of a proportional solenoid; a venting air-resistor of which the rear end has the fixed drift diameter is matched with the drift diameter of the proportional solenoid; and the rear end of the body of the proportional solenoid achieves different PEEP pressure set values. The control method comprises the following steps: obtaining the current PEEP pressure; judging whether the PEED pressure is normal; if yes, clearing a regulation record; judging whether PEED pressure is regulated; regulating the current of the proportional solenoid, and returning; judging whether current PEEP pressure is too much or too little; switching on a two-digit three-way solenoid valve, and returning; judging whether the regulation record exists if the current PEEP pressure is too much; if no, regulating the current of the proportional solenoid, and returning; and switching off the two-digit three-way solenoid valve.

Description

technical field [0001] The invention relates to a ventilator positive end-expiratory pressure control system, a circuit and a control method thereof. 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. [0003] CN200910217574.3 discloses a "control system and method for dual-level pressure in the airway, ventilator and anesthe...
