Quick response type automatic respiration controller

Abstract

The invention discloses a quick response type automatic respiration controller, and belongs to artificial auxiliary respiration support equipment in the non-medical special field. The quick response type automatic respiration controller comprises a dust removal filter, an activated carbon filter, a flow-adjustable air pump, a pressure stabilizing air tank, an adjustable pressure reducing valve, an electromagnetic valve, a gas mass flow meter, a program control power supply, a humidifier and a positive pressure type one-way valve respiration mask. The dust removal filter, the activated carbon filter, the flow-adjustable air pump, the pressure stabilizing air tank, the adjustable pressure reducing valve, the electromagnetic valve, the gas mass flow meter, the humidifier and the positive pressure type one-way valve respiration mask are sequentially arranged, and the program control power supply is used for controlling the on-off of the electromagnetic valve. According to the quick response type automatic respiration controller provided by the invention, the parameter adjusting capacity is high, the gas flow / pressure stability is good, on-off of gas intermittent adopts a program control power supply to control on-off of the electromagnetic valve, the response is sensitive, the time lag is small, and the gas purifying capacity is high. The quick response type automatic respiration controller is simple, portable, high in universality and wide in market prospect.

Description

technical field [0001] The invention belongs to the technical field of medical care, and relates to ventilator control technology and equipment with quantitative, constant pressure, constant frequency and fast response without delay, in particular to a fast-response automatic breathing controller. Background technique [0002] With the continuous improvement of medical technology, the function of respirator products is no longer limited to first aid or rescue, and at the same time bears the function of related treatment. The quality requirements for such products are gradually increasing. Therefore, the demand for respirator products in my country is showing a continuous upward trend. Domestic respirators appeared relatively late in my country, and most of them are used for patients who cannot breathe normally, lung failure and airway obstruction. Patients with sleep apnea syndrome, including snoring and apnea, are often used with home respirators, and patients with severe p...

AI Technical Summary

Problems solved by technology

[0005] However, the existing respirators have the following problems: (1) Poor parameter adjustability: the gas flow and pressure output by the existing household respirators are basically in the state set by the manufacturer, and the parameters are fixed and homogeneous. However, due to the different physical conditions of the users, there are great differences in the gas flow and pressure requirements output by the respirator. On the whole, there are widespread problems such as poor use effect and poor tolerance.

(2) Poor gas flow and pressure stability: Most of the existing household respirators adopt the direct gas supply mode of the gas pump. Large fluctuations, especially when high-frequency intermittent air supply is required, the actual air supply flow and pressure level of the existing equipment deviate significantly from the set parameters of the instrument, resulting in poor user experience and effect

(3) Poor gas purification ability: due to widespread air pollution, there are more particulate matter that can enter the lungs in the air, and a large number of bacteria and viruses will attach to the surface of the particulate matter that can enter the lungs and enter the human respiratory system

Most of the people who need to use household respirators have mild or severe chronic diseases, poor physical fitness, and are more likely to be harmed by inhaled pollutants and bacterial viruses, which can lead to more serious respiratory diseases. The respirator has limited ability to purify gas, and there is a risk of respiratory system infection during use

(4) Singularization of functions: a large proportion of the population who need to use household respirators also need to use other medical care methods. Oxygen inhalation, existing products do not have the function of connecting with other healthcare technologies
