Respirator flow rate control device based on synchronous intermittent ventilation

Abstract

The invention discloses a respirator flow speed control device based on synchronous intermittent ventilation, which comprises a breathing machine and is characterized in that a downstream pipeline of the breathing machine is connected with a pump body, a downstream pipeline of the pump body is connected with a flow adjusting mechanism, and a downstream pipeline of the flow adjusting mechanism is connected with a mask. An induction mechanism is fixedly connected to the interior of the mask, the induction mechanism is connected with a flow adjusting mechanism pipeline, the flow adjusting mechanism comprises a control box, a taper hole is formed in the bottom of the control box, a pull rope is fixedly connected to the bottom of the control box, and a taper plug is fixedly connected to the other end of the pull rope; and a partition plate is arranged in the taper plug, convection holes are formed in the partition plate, an upper cavity is formed in the upper end of the taper plug, a lower cavity is formed in the lower end of the taper plug, and gas is arranged in the upper cavity. The respirator flow rate control device has the advantages of being high in practicability and capable of automatically adjusting the flow of introduced positive-pressure air flow.

Description

technical field [0001] The invention relates to the technical field of household ventilators, in particular to a ventilator flow rate control device based on synchronous intermittent ventilation. Background technique [0002] The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. With the development of the ventilator, its application is not limited to hospital use, portable household breathing The use of ventilators is becoming more and more widespread, and it has a good effect in treating snoring and apnea. The current anti-snoring ventilators provide a constant positive pressure airflow continuously to blow open the blocked airway, so that they can effectively Improve snoring and apnea symptoms, but this constant positive pressure airflow will fight against the respiratory system when the human body exhales, causing certain damage to the respiratory system, especially for pe...

[0002] The ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. With the development of the ventilator, its application is not limited to hospital use, portable household breathing The use of ventilators is becoming more and more widespread, and it has a good effect in treating snoring and apnea. The current anti-snoring ventilators provide a constant positive pressure airflow continuously to blow open the blocked airway, so that they can effectively Improve snoring and apnea symptoms, but this constant positive pressure airflow will fight against the respiratory system when the human body exhales, causing certain damage to the respiratory system, especially for people with weak breathing ability. Because the degree of airway blockage is closely related to snoring, according to the needs of the human body, positive pressure airflow can be provided synchronously with the inhalation action, and the pressure of the inflow airflow can be slightly reduced when exhaling, so that the exhalation and inhalation can be achieved. There is a certain pressure difference between the gas to reduce the pressure on the human lungs when exhaling. At the same time, the flow of gas can be adjusted according to various situations to meet the needs of treatment and human comfort. Therefore, the design is practical A ventilator flow rate control device based on synchronous intermittent ventilation that strongly and automatically adjusts the positive pressure air flow is necessary
