Is not a lot of people with small make-up the same, the new year on the recruit unknown virus, a whole state is“Cough cough cough”, plus throat expectoration. 

      For a few moments, I even wondered if I should buy a sputum dispenser. The expectoration machine can help patients expectoration in clinic, which mainly imitates the process of respiratory system movement and the way of exhaled airflow, and alternately gives positive pressure support and negative pressure suction. Positive pressure inspiratory airway, bronchiectasis, increase the patient's diaphragm movement, increase alveolar ventilation, can lead to sputum plug loose. The negative pressure exhales, the alveolus inside pressure increases, causes in the lung the airflow to expel high speed, simultaneously pushes the phlegm suppository to the big airway movement, causes it to be easy to cough. Speaking of sputum dispensers, did you know that voice coil motors are already in use in this field. A sputum dispenser usually has two voice coil motors, and one is used as a drive device in the inspiratory module, an exhalation component in the drive device, through the voice coil motor high-frequency vibration, to achieve the related action. 

        Kunshan Tongmao Electronics Co. , Ltd. has been deeply cultivating the voice coil motor field for more than ten years. The voice coil motor made in Tongmao adopts European and n technical standards and processing technology, and is widely used in the biomedical field, like expectoration machine, breathing machine and other medical equipment, I have voice coil motor figure, welcome more attention.
