Disposable automatic negative pressure drainage device

Abstract

A disposable automatic negative pressure drainage device, comprising an infusion tube puncturer, an infusion tube, a drainage tube, a drainage tube, and a effusion bag, characterized in that: the infusion tube puncturer, infusion tube, drainage tube, and drainage tube The effusion bags are connected in sequence to form a "D" shape, the drainage tube has a medical one-way liquid valve, and the infusion tube has a transparent drip pot and a flow regulating valve. The beneficial effect of the present invention is that the medical one-way liquid-through valve can prevent the drained liquid from flowing back to the drainage lesion site, which can effectively prevent retrograde infection, and the liquid in the drainage tube flows to the effusion through the drainage tube due to gravity and siphon effect bag, so that a continuous and stable negative pressure is automatically formed in the drainage tube. The continuous liquid supply of the infusion tube can maintain the liquid in the drainage tube, prevent the siphon effect in the drainage tube from disappearing when the gas is drained, and facilitate pre-hospital first aid, first aid in the field and transport of the wounded.

Description

technical field [0001] The invention relates to a medical drainage device, in particular to an automatic negative pressure drainage device for surgical drainage. Background technique [0002] At present, there are deficiencies in many drainage devices such as drainage tubes connected with drainage bags, drainage tubes connected with manual negative pressure generators and electric negative pressure generators, etc., which are commonly used for drainage in known surgery. The method cannot form a continuous and stable negative pressure, and the drainage effect is not sufficient. Improper operation can also cause the drained liquid to flow back to the drainage site, which may cause retrograde infection; the drainage tube is connected to a manual negative pressure generator for drainage, and the negative pressure cannot Continuous and stable maintenance and precise regulation, improper operation can also cause the drained liquid to flow back to the drainage site; although the el...

[0002] At present, there are deficiencies in many drainage devices such as drainage tubes connected with drainage bags, drainage tubes connected with manual negative pressure generators and electric negative pressure generators, etc., which are commonly used for drainage in known surgery. The method cannot form a continuous and stable negative pressure, and the drainage effect is not sufficient. Improper operation can also cause the drained liquid to flow back to the drainage site, which may cause retrograde infection; the drainage tube is connected to a manual negative pressure generator for drainage, and the negative pressure cannot Continuous and stable maintenance and precise regulation, improper operation can also cause the drained liquid to flow back to the drainage site; although the electric negative pressure generator can generate continuous and stable negative pressure, the cost is high and the use is inconvenient, which limits its wide application
