Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] Such as figure 1 As shown, the intelligent outflow resistance switching simulated breathing device is composed of fan 1, air buffer chamber 2, inlet flow sensor 3, air bag 4, outlet flow sensor 5, air valve 6, pressure sensor 7 and signal processing and control unit 8. Wherein, the signal processing and control unit 8 includes a signal processing and control circuit and signal processing and control software loaded on a computer. The air buffer chamber 2 has 3 round ports, port 1 communicates with the fan 1, port 2 is connected to the air bag 4 through a hose to form an intake channel, the intake air flow sensor 3 is fixed on the intake channel, and port 3 is connected to the air bag through a hose. The valve 6 forms an exhaust channel, the outlet flow sensor 5 is fixed on the exhaust channel, and the pressure sensor is fixed on the air buffer c...

Abstract

The invention discloses an intelligent outflow resistance switching simulation breathing apparatus, which comprises a fan, an air cushioning cavity, an inlet airflow sensor, an airbag, an outlet airflow sensor, an air valve, a pressure sensor and a signal processing and control unit, wherein the signal processing and control unit comprises a signal processing and control circuit and computer-loaded signal processing and control software; and signal transmission is achieved by virtue of an information acquisition card, so that the breathing apparatus is driven and controlled. The breathing apparatus disclosed by the invention can be used for automatically controlling a tidal volume and a ventilation rhythm by automatically adjusting the motion amplitude and the motion rhythm of the valve. In addition, the breathing apparatus is designed with intelligent regulating and control functions such as ventilation supporting strength determination and control function, lung injury ventilation function, apnea automatic handling function and the like, so as to provide appropriate ventilation support strength to patients, reduce related lung injury of the breathing apparatus and guarantee the ventilation safety of the patients on the breathing apparatus.

Description

technical field [0001] The invention relates to an intelligent outflow resistance switching simulation breathing device, which belongs to the technical field of medical instruments. Background technique [0002] The completion of external respiration requires the participation of two processes of pulmonary ventilation and pulmonary ventilation, that is, the gas exchange between the outside world and the alveoli is realized through the airflow movement in and out of the airway, and the gas exchange between the alveoli and the blood is realized through blood circulation. The movement of the airflow in and out of the airway in the airway requires thoracic activity to power it. Under pathological conditions, if the respiratory muscles that pull the thoracic activity lose their nerve impulses, or the respiratory muscles are fatigued and cannot effectively contract, a ventilator is needed. To replace or assist the respiratory muscles to provide effective power support for airflow ...
