device can be used continuously, through setting up gasbag 402 and holding chamber 404, make when holding chamber 404 is inside to produce the negative pressure, accessible gasbag 402 inside air admission holds chamber 404 inside and makes the gasbag 402 reduce prevent that to make the inside of hydrops bottle 3 produce the negative pressure, make the mode of producing the negative pressure comparatively gentle, be convenient for gently extract the hydrops, gasbag 402 reduces to when minimum simultaneously, accessible gasbag 402 overturns and is expanding in the inside of holding chamber 404 in the inside of third connecting pipe 401, can make hydrops bottle 3 cooperation drainage subassembly 1 can extract more hydrops when preventing that the inside hydrops of hydrops bottle 3 from getting into holding chamber 404 inside, simultaneously because the hydrops can not get into the inside of holding chamber 404, and third connecting pipe 401 is convenient to dismantle with holding chamber 404, this just makes holding chamber 404 and fixed casing 407 can continue to use.
