Problems solved by technology

The disadvantage of this control method is that the respiratory rate cannot change significantly, otherwise it will cause the input pressure of the ventilator (that is, high pressure during inhalation and low pressure during exhalation) to mismatch with the patient's respiratory state, which will further aggravate the patient's anxiety. Respiratory disorder, serious or even endanger the patient's life safety

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like figure 1 Shown, a kind of bilevel ventilator pressure control device is characterized in that: comprising:

[0025] Turbo fan: used to generate compressed air;

[0026] Turbo fan drive controller: used to drive the turbo fan, the turbo fan drive controller includes a servo controller, and the servo controller is a closed-loop system controlled by a feedforward controller and a feedback controller;

[0027] Sensor: used to detect the actual pressure of the patient's airway in real time;

[0028] Air path: formed by a hose connection, the turbo fan is connected to the nasal mask through a hose to form an air path, between the sensor and the turbo fan drive controller and between the turbo fan drive controller and the turbo fan They are connected by electric wires, and the sensor is also communicated with the hose.

[0029] The feed-forward controller is u...

Abstract

The invention discloses a pressure control device and method for a double-level respirator. The pressure control device is characterized by comprising a turbofan, a turbofan driving controller, a sensor and an air path, wherein the turbofan is used for generating compressed air; the turbofan driving controller is used for driving the turbofan and comprises a servo controller, and the servo controller is a closed loop system under the compound control of a feedforward controller and a feedback controller; the sensor is used for real-time detection of the actual pressure of the airway of a patient; the air path is formed by connecting hoses. According to the pressure control device and method for the double-level respirator, the design is reasonable, the functions of real-time detection and real-time adjustment of first output pressure and final output pressure are achieved, the anti-interference function is also achieved, and the pressure control device is more intelligent, safe and reliable.

Description

technical field [0001] The invention relates to a bilevel ventilator, in particular to a device and method for controlling the pressure of a bilevel ventilator, and belongs to the field of medical devices. Background technique [0002] Snoring is a ubiquitous sleep phenomenon. At present, most people think that it is commonplace, and they don't take it seriously. Some people regard snoring as a sign of a sound sleep. In fact, snoring is the enemy of health. At present, as people's awareness of poor breathing, such as snoring, can cause various diseases, ventilators are often used in family rehabilitation. The reasons for snoring can generally be divided into three types: one is due to the narrowing of the patient's airway, such as caused by diseases such as nasal polyps; the other is due to indoor hypoxia, which causes the patient to breathe with his mouth open during sleep; the third is sleep breathing controlled by autonomic nerves. Apnea syndrome, that is, snoring after ...
