Document Type and Number:
WIPO Patent Application WO/2017/063498
Kind Code:
A1
Abstract:
An expectoration system comprises an expectoration pipe (20) comprising a throttling device (21) and a balloon valve (19); an expectoration machine (1), comprising a main pipe assembly (15), an air pump assembly (2) and a control system (8). The main pipe assembly (15) comprises a fan (16) and a shutter valve (17). The air pump assembly (2) comprises a first air pump (6) and a second air pump (3). The control system (8) comprises a first sensor (12) for measuring an air pressure of the throttling device (21), and comprises a microcomputer control unit. The microcomputer control unit determines a patient being in an exhaling or inhaling stage by means of an air pressure difference detected by the first sensor (12); during expectoration, the first air pump (6) supplies air to the balloon valve (19) to disconnect a respirator air path, the fan (16) and shutter valve (17) are opened to control the second air pump (3) to supply air to the throttling device (21), and a respirator does not stop running in the expectoration sage.
