A high-efficiency medical anti-blockage drainage device and its application method

Abstract

The invention provides a high-efficiency medical anti-clogging drainage device and its use method. The high-efficiency medical anti-clogging drainage device includes a drainage tube, a leaf-shaped filter, a negative pressure tube, a mixing tube, and a fixed trap; the side wall of the drainage tube is provided with a plurality of The first through hole; the inside of the drainage tube is provided with a blade-shaped filter screen; the blade-shaped filter screen is in the shape of a cone; the tapered portion of the blade-shaped filter screen and the inner wall of the drainage tube form a negative pressure tube connection port; the negative pressure tube connection port is provided with There are helical blades; the connection port of the negative pressure tube is connected to the negative pressure device; the first through hole is located under the blade-shaped filter; when the negative pressure device is working, the spiral blade rotates; the mixing tube is connected to the nozzle of the drainage tube; the mixing tube is used for Flushing liquid or gas is poured into the drainage tube; the negative pressure tube and the mixing tube are fixed inside the drainage tube through a fixed snare; the fixed snare is provided with a ventilation hole. With the high-efficiency medical anti-clogging drainage device provided by the invention, the drainage tube will not be blocked during use, and the polluted tissue fluid inside the body cavity can be drained cleanly.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a high-efficiency medical anti-blockage drainage device and a method for using the same. Background technique [0002] There are many types of surgical drainage tubes used clinically, some are used for catheterization, and some are used for wounds, chest cavity, brain cavity, gastrointestinal tract, biliary tract, etc. Surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or body cavities to the outside of the body to prevent postoperative infection from spreading and affecting wound healing. [0003] At present, most of the various drainage tubes commonly used in clinical practice have single functions, can only drain, and cannot be washed, and there are only a few drainage tubes that can be washed, but their design is unreasonable. The water pipe is set in the suction pipe, and the water flow cannot be released into the human organs and tissue...

Problems solved by technology

[0003] At present, most of the various drainage tubes commonly used in clinical practice have single functions, can only drain, and cannot be washed, and there are only a few drainage tubes that can be washed, but their design is unreasonable. The water pipe is set in the suction pipe, and the water flow cannot be released into the human organs and tissues outside the pipe, resulting in a dead cycle in which the water is sucked out in the pipe after entering the water, which cannot play the role of washing the human organs and tissues

Chinese patent (application number: 201520472866.2, publication date: January 13, 2016) discloses a medical flushing and drainage tube. The flushing and drainage tube provided by the patent is provided with an outer sleeve, an inner sleeve and two side tubes. Embedded inside the outer cannula, the two side tubes are set outside the inner cannula. When in use, the space between the second side tube and the first side tube may be blocked by human tissue, and at the same time, there is no way to connect the tissues in the wound or the body cavity. The pus, blood, and fluid accumulated in the wound are diluted and completely drained to the outside of the human body, which can easily cause wound infection

Although some drainage tubes in the prior art have flushing function, the interstitial fluid washed out from the human body will easily lead to blockage of the drainage tube, thus causing the drainage tube to fail to continue to perform the drainage function. In severe cases, it will cause secondary pollution of the patient's surgical wound
