The first body UNICOM, the 4th body and the first body UNICOM are stated, fluorescence is provided with the inwall of the 3rd body
Material, one end of the 4th body is provided with removable tip 5, and the tip is located at the other end of the conduit；
Wherein, first body and the 3rd body are flexible pipe, the diameter of the diameter less than the conduit of the seal wire.
Seal wire and conduit are set and are formed in one by CVC of the invention, are easy to use, in the front end of seal wire
Extensible tip is provided with, it is necessary to defect with disposable syringe during eliminating the need for, it is to avoid equipment is wasted.Also, this
Nano silver material is coated with the inwall of the first body of invention, so the conduit can be used for ultrasound detection, to determine that its is specific
Position, and be coated with fluorescent material on the 3rd pipe inner wall of the invention, fluorescence is sent in detection, with can be more accurately
Determine its position, and the first body of the invention and the second body are set to flexible pipe, it is to avoid the injury to user.
Device of the invention can quickly and accurately clear and definite its position, and eliminate the step for needing to use disposable syringe
Suddenly, the operating efficiency of medical personnel is improve, the discomfort of user is alleviated.
In one of embodiment of the invention, preferably, in the CVC, second body and
Four bodys are made of Ultimum Ti material.To mitigate user's immoderation.
In one of embodiment of the invention, preferably, first body and the 3rd body are by insulating materials
