Thoracic anti-blocking drainage apparatus for thoracic surgery

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thoracic cavity anti-blockage drainage device for thoracic surgery. Background technique [0002] At present, thoracic drainage is a commonly used treatment method in the field of thoracic surgery. During the treatment, the gas and liquid in the patient's thoracic cavity need to be discharged from the body in time; The drainage tube is used to suck out the waste fluid and gas in the chest cavity, and a large amount of pollutants will remain on the inner wall. If the same tube is still used for injection, it will cause infection and reduce the safety of treatment; A large number of waste objects with large particles can easily block the drainage tube, which is extremely inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a thoracic cavity anti-blocking and d...
