DETAILED DESCRIPTION
[0021] The utility model will be further illustrated in conjunction with the drawings and specific embodiments, and it should be understood that the following specific embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.
[0022] As Figure 1 , Figure 2 and Figure 3As shown, a medical drainage tube includes a drainage tube; the drainage tube 1 tube body retains a threaded layer 2, the threaded layer 2 upper and lower ends are respectively screwed with a limiting sleeve 8 and a branch pipe sleeve 7, the drainage tube 1 tube body along the threaded layer 2 is provided with a pipeline branch port 7-1, the pipeline branch port 7-1 is in drainage butt joint with the drainage port 4 of the branch pipe sleeve 7; wherein the threaded layer 2 retained by the drainage tube 1 tube body is respectively sleeved with the limiting sleeve 8 and the branch pipe sleeve 7 to limit the flow of the pipeline branch port 7-1. The initial state of the branch pipe sleeve 7 and the limiting sleeve 8 is located at the root position of the threaded layer 2, which ensures that the limiting sleeve 8 can fully cover the pipeline branch port 7-1, achieving the effect of sealing and preservation, and in the later use process, the limiting sleeve 8 can be adjusted upwardly in a spiral manner. At the same time, the drainage port 4 of the branch pipe sleeve 7 is communicated with the pipeline branch port 7-1, achieving the effect of drainage.
[0023] The bottom end of the limiting sleeve 8 is in synchronous butt joint with the branch pipe sleeve 7 through a synchronous joint 12, and the inner wall of the limiting sleeve 8 is in sealing contact with the pipeline branch port 7-1. In the process of synchronous butt joint of the limiting sleeve 8 and the branch pipe sleeve 7, synchronous spiral downward rotation adjustment can be achieved, finally all pipelines for drainage are closed, finally the drainage tube is destroyed, and secondary infection is avoided.
[0024] As shown in Figure 1 , Figure 2 and Figure 3 , the branch pipe sleeve 7 is provided with a drainage port 4 along the front end surface, the port position of the drainage port 4 is in sealing butt joint with an external branch pipeline through a sealing ring; an internal port 9 is arranged in the drainage port 4, and the internal port 9 is a converging type drainage port. In this way, the internal port 9 can assist the external branch pipeline in flow butt joint.
[0025] As shown in Figure 1 , Figure 2 and Figure 3 , the branch pipe sleeve 7 is provided with a finger groove 10 on both sides of the sleeve body. In this way, the design of the finger groove 10 can enhance the operation feeling.
[0026] As shown in Figure 1 , Figure 2 and Figure 3 , the limiting sleeve 8 is provided with a visible window 3 along the front end surface, and the visible window 3 is in visible matching alignment with the pipeline branch port 7-1. In this way, the visible window 3 can observe whether the pipeline branch port 7-1 can be completely blocked in a closed state.
