Breathing control system

Abstract

The invention discloses a breathing control system, and belongs to the field of breathing control. The system comprises a face mask, a first control device, a second control device, a buffer cavity, an air source device, an oxygen device and a humidifying device, wherein the face mask, the second control device, the buffer cavity and the first control device are sequentially connected; each of theair source device, the oxygen device and the humidifying device is provided with two interfaces; the two interfaces are respectively connected with the first control device and the second control device through air pipes; each corresponding air pipe is provided with an electromagnetic valve; and a plurality of monitoring and control modules are arranged in the first control device and the secondcontrol device and are used for realizing double control. Therefore, the whole respiratory control system has better safety stability and more timely response.

Description

technical field [0001] The invention relates to the technical field of respiration, in particular to a ventilator control system. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. The completion of human spontaneous breathing mainly depends on the pressure difference formed between the expansion and contraction of the alveoli and the atmospheric pressure, and the ventilator uses a mechanical method to establish the pressure difference between the lungs and the atmosphere to achieve artificial respiration. It is a device that replaces or controls people's physiological breathing, maintains proper lung ventilation,...

Problems solved by technology

[0003] Most of the existing ventilators are single-control mode, that is, there is only a single device to control the flow rate and humidity, etc. However, problems such as tracheal obstructions and aging of electronic products have always existed, which will cause great uncertainty

For example, in the existing ICU and other wards, there is a situation where one person monitors multiple people. In extreme cases, two ventilators have problems at the same time, and it is often difficult to achieve synchronous rescue; Delay, poor accuracy and other issues
