| titleOfInvention | exhalation aid |
| abstract | The utility model relates to an exhalation auxiliary device. The structure comprises a volume flow change tank. The inner wall of the volume flow change tank is a tapered surface. The diameter of the upper end of the inner wall of the volume flow change tank is slightly larger than the diameter of the lower end. The floatable valve body is connected with an air intake pipe, an exhalation valve, a flow regulating valve and a carbon dioxide concentration sensor connected in series at the bottom of the volume flow change tank. A positive and negative pressure air source is connected to the top of the volume flow changing tank, and a solenoid valve, a pressure regulating valve, a flow regulating valve and a flow sensor are connected in series on the positive and negative pressure gas sources. Through the method of mixing positive and negative pressure, the problem of differences in exhalation caused by different conditions of each patient is solved. That is, to prevent insufficient exhalation and to prevent excessive exhalation. The poisonous gas exhaled by the patient is uniformly recycled and processed through the negative pressure pipeline to prevent cross-infection of medical personnel. Saving resources is conducive to scientific management of environmental protection and biosafety, and accelerates the recovery of patients' lung function through assisted exhalation. |
