Washing and drainage device for high position fistula

Abstract

The invention relates to a washing and drainage device for a high position fistula, aims to overcome the problems in the prior art that a silk thread or a drainage tube in a high position fistula ligation therapy is easy to fall, and the ligation therapy cannot effectively drain the pus in an internal mouth of the fistula when the position of the fistula is high or the wound of the internal mouthis large, resulting in premature false healing of an external mouth, and non-healed fistula interior, and provides a washing and drainage device for the high position fistula, including: a washing anddrainage tube and a negative pressure drainage bottle, wherein one end of the washing and drainage tube is uniformly provided with a set of washing and drainage holes, and the other end of the washing and drainage tube is provided with a washing port and a drainage port; the outer wall of the washing and drainage tube is provided with a water bag; the negative pressure drainage soft bottle is connected with the drainage port through a conduit. The device of the invention can effectively clean the interior of the high position fistula, and continuously maintain the negative pressure and timelydrain the pus in the internal mouth of the fistula; the water bag clamps the fistula wall to prevent the drainage tube from falling from the fistula; the fistula is gradually healed from the inside to the outside, and the device is suitable for high position fistula care.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a flushing and drainage device for high fistula. Background technique [0002] High fistula: refers to the fistula and its branches above the levator ani and the anorectal ring, which is difficult to treat. At present, the most effective treatment method is surgery combined with hanging thread therapy. The mouth is drawn into the internal mouth, and finally the anus is drawn out through the rectal curvature, and then ligated with a slipknot. However, thread hanging therapy has the following disadvantages: when flushing the fistula, too much drainage fluid will easily cause the silk thread to fall off, and re-hanging the thread will increase the pain of the patient; The external opening has healed, but the internal opening has not healed, resulting in the pus in the internal opening cannot be discharged in time, affecting the healing of the fistula. Especially for high-level fistu...
