As described above, since both the nebulizer and the aspirator use the positive pressure or the negative pressure of the pump, it is possible to operate both with a single pump (for example, Utility Model Registration No. 30).
No. 36332). However, in the case of medical devices, even if the nebulizer and the aspirator have independent and separate circuits, if both are used at the same time, there is a risk that an unexpected accident such as infection may occur. Devices that can be used have been deprecated. However, if a pump is combined with each of the nebulizers and aspirators to form independent devices, the devices become unnecessarily large and uneconomical.
