A Diaphragm Stimulated Inhalation and Exhaust System

Abstract

The present invention relates to the medical and health field, and provides a diaphragm stimulation suction and exhaust system, including a positive pressure ventilation module, a negative pressure suction module, a patient interface module, a central processing module, and an electric / magnetic stimulation module, wherein: the positive pressure ventilation module, Used to generate positive pressure airflow; negative pressure suction module, used to generate negative pressure airflow; patient interface module, allowing positive pressure and negative pressure airflow to flow; positive pressure ventilation module, negative pressure suction module and patient interface module Connected through a three-way device; the central processing module is connected with the three-way device and the electric / magnetic stimulation module; the central processing module controls the positive pressure ventilation module, the negative pressure suction module and the patient interface module through the three-way device On and off, and control whether the electric / magnetic stimulation module works or not.

Description

technical field [0001] The invention relates to the medical and health field, and provides a diaphragm stimulation suction and exhaust system. Background technique [0002] For mechanically ventilated patients, the discharge of deep lung secretions is very important to prevent ventilator-associated pneumonia. At present, the commonly used sputum suction methods in clinical practice include open sputum suction and closed sputum suction. The open sputum suction method means that the patient disengages the ventilator, gently inserts the sputum suction tube into the respiratory tract, and presses the negative pressure suction device to suck sputum. The sputum suction operation does not need to be disengaged from the ventilator or stop the mechanical ventilation. The sputum suction tube is covered with a transparent film, and the entire sputum suction process is completed under airtight conditions. The above two sputum suction methods not only require the staff to have skilled ...

AI Technical Summary

Problems solved by technology

If you only simulate the airflow movement in the simulated expectoration without stimulating the main respiratory muscle - the diaphragm, it will affect the intensity of coughing and expectoration, which is not conducive to the discharge of sputum

Moreover, if the cough is only simulated from the airflow, if the muscles cannot be contracted accordingly, it will cause lung damage and even collapse of the alveoli
