Problems solved by technology

[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

Embodiment Construction

[0009] In the figure, a disposable automatic negative pressure drainage device includes an infusion tube puncturer 1, an infusion tube 2, a drainage tube 6, a drainage tube 8, and an effusion bag 9, and is characterized in that: the infusion tube puncturer 1 , infusion tube 2, drainage tube 6, diversion tube 8, and effusion bag 9 are sequentially connected to form a "D" shape, the drainage tube 6 has a medical one-way liquid valve 7, and the infusion tube 2 has a transparent drop Kettle 3 and flow regulating valve 4. During use, the effusion bag 9 is lower than the drainage hole 5, the infusion tube 2 is higher than the drainage hole 5, the flow regulating valve 4 is opened, and the liquid is continuously dripped at a rate of 30-60 drops / min. The liquid in the infusion tube 2 is due to gravity and The siphon effect flows to the effusion bag 9 through the drainage tube 8. During this process, a continuous and stable negative pressure can be formed in the drainage tube 6, and th...

Abstract

An automatic disposable vacuum drainager comprises an infusion tube puncture device, an infusion tube, a drainage tube, a diversion tube and a liquid accumulation bag. The automatic disposable vacuum drainager is characterized in that the infusion tube puncture device, the infusion tube, the drainage tube, the diversion tube and the liquid accumulation bag are connected in sequence to form the shape of T, the drainage tube is provided with a medical one-way liquid instillation valve, and the infusion tube is provided with a transparent drip cup and a flow control valve. The automatic disposable vacuum drainager has the advantages that the medical one-way liquid instillation valve can stop drained liquid from flowing back to the lesion location of drainage, retrograde infection can be effectively prevented, liquid in the drainage tube flows into the liquid accumulation bag through the diversion tube due to the action of gravity and siphonic action, continuous and stable negative pressure is automatically formed in the drainage tube, the infusion tube supplies the liquid continuously to maintain the liquid inside the drainage tube, the phenomenon that the siphonic action in the drainage tube disappears when gas is drained is prevented, and pre-hospital care, battlefield first aid, injured transport and the like are convenient to achieve.

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...
