Technical Field
The utility model relates to a universal cock for a disposable sterile drainage bag, belonging to the technical field of medical appliances.
Background
In clinical work, various drainage tubes (including PTCD drainage tubes, liver abscess, hepatic cyst, abdominal cavity drainage tubes, thoracic drainage tubes and the like) applied in various effusion/pus, obstructive jaundice and surgical drainage cannot be directly connected with an external drainage bag, and an intermediate adapter or a rubber strip is needed for connection; at present, in clinical practice of various hospitals, infusion apparatus connectors are commonly used for self-made connectors or plastic short pipes with two contracted ends of drainage bags are used for connection. The infusion set joint is self-made, so that pollution risks exist, and the requirement of sterile quality control is not met; the plastic short pipe which is contracted from the two ends of the drainage bag is easy to fall off, and the risk of pollution caused by falling off exists for a patient needing long-term tube placement drainage.
In the prior art, various drainage tube structures are single, and the tail end interface is designed as an external screw port; the interfaces of most drainage bags in the market are also external threads, so that the two drainage bags can not be directly connected, auxiliary connection is needed by connecting rubber tubes in the middle, and the connection is not firm and the operation is inconvenient; therefore, a general cock is needed clinically to realize the connection of various drainage tubes and drainage bags of different types, and to facilitate the sampling operation.
Disclosure of Invention
The utility model aims to solve the technical problem of how to obtain a universal cock to realize connection of various drainage tubes and drainage bags of different types.
In order to solve the above-mentioned problem, the technical scheme adopted by the utility model is to provide a disposable aseptic drainage bag universal cock, comprising a three-way cock, a hollow pagoda joint and a hollow truncated cone-shaped elastic connecting pipe; the three-way cock is provided with a linear passage and a side branch passage, one end of the linear passage is provided with an external thread interface, and the other end of the linear passage is provided with an internal thread nut I; one end of the pagoda joint is provided with a pagoda joint for being connected with the elastic connecting pipe, and the other end of the pagoda joint is provided with an internal thread nut II for being connected with an external thread interface of the tee cock linear passage.
Preferably, a channel for liquid circulation is arranged in the pagoda joint; the passage arranged in the internal thread nut II is tightly matched with the external thread interface of the straight passage of the three-way cock.
Preferably, two ends of the elastic connecting pipe are respectively provided with a large-caliber interface and a small-caliber interface; the small-caliber interface is connected with the pagoda-shaped connector.
Preferably, the elastic connecting pipe is a latex pipe.
Preferably, the pagoda joint is made of plastic materials.
Compared with the prior art, the utility model has the following beneficial effects:
the product of the utility model is sterile, disposable, simple and easy to operate. The utility model provides more convenient and stable connection between the drainage bag and the drainage tube; is suitable for connecting drainage bags with various specifications.
