The invention discloses a thoracic anti-blocking drainage apparatus for thoracic
surgery. The drainage apparatus comprises an accommodating box and a drainage tube, wherein an air
pressure sensor is fixed to the upper side of the inner wall of the accommodating cavity (the accommodating box); a negative-pressure pump is fixed to the upper surface of the accommodating cavity; an air intake end of the negative-pressure pump communicates with one end of an air intake tube, and the other end of the air intake tube runs through and extends to the interior of the accommodating box; a holding box is fixedly arranged on the left side face of the accommodating cavity; a
single chip, an
electrical control switch and a storage battery are fixedly arranged in the holding box sequentially from top to bottom; a liquid inlet of the accommodating cavity communicates with a liquid outlet cavity of the drainage tube by virtue of a liquid
guide tube; a
check valve is arranged on the liquid
guide tube; the
single chip is electrically connected to the
electrical control switch, the storage battery and the air
pressure sensor; a fixing plate and an
airbag cooperate for use, so that a tube body, which stretches into a
human body, is prevented from shaking due to movement of an external apparatus, and pain in a patient is prevented; and the interior of the tube body is divided into two areas, namely a liquid inlet cavity and the liquid outlet cavity, so that
human body infection caused by waste solutions is prevented and
medical safety is guaranteed.
