Detailed Description

The core of the utility model is to provide a medical catheter, which avoids the injury to human body.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, an embodiment of the present invention provides a medical catheter, including a first tube 1, a second tube 2 and a developing ring 3, wherein one end of the first tube 1 is fixed in one end of the second tube 2, the developing ring 3 is forged on an outer side of a tube wall of the first tube 1, which is sleeved in the second tube 2, and the developing ring 3 is wrapped in the second tube 2. Because the developing ring 3 is arranged in the position where the first pipe body 1 and the second pipe body 2 are sleeved, the developing ring 3 is not exposed outside, and therefore, after the medical catheter is inserted into a human body, the developing ring 3 does not directly contact with a cavity and a blood vessel of the human body, the human body tissue cannot be damaged, heavy metal ions cannot be separated out to harm the human body tissue, and the sensitization risk is avoided.

Further, in this embodiment, the outer surfaces of the first pipe 1 and the second pipe 2 are flush, that is, the outer diameters of the first pipe 1 and the second pipe 2 are the same, and in order to sleeve one end of the first pipe 1 to one end of the second pipe 2, one end of the first pipe 1 is subjected to necking treatment, so that the outer diameter of the necking end 11 of the first pipe 1 is smaller than or equal to the inner diameter of the second pipe 2. Through the surface parallel and level that makes first body 1 and second body 2, make the surface of medical catheter smooth, reduced to cause the scraping injury to human tissue, remove more smoothly. Of course, the outer diameter of the second pipe body 2 may also be larger than the outer diameter of the first pipe body 1, as long as one end of the first pipe body 1 is sleeved on one end of the second pipe body 2.

Further, in the present embodiment, the inner surfaces of the first tube 1 and the second tube 2 are flush, that is, the inner diameters of the first tube 1 and the second tube 2 are the same, specifically, one end of the first tube 1 is a reduced end 11, one end of the second tube 2 is a flared end 21, the outer diameter of the reduced end 11 is less than or equal to the inner diameter of the flared end 21, the developing ring 3 is forged and pressed outside the reduced end 11, and the reduced end 11 is sleeved in the flared end 21. By making the inner surfaces of the first tube body 1 and the second tube body 2 flush, instruments in the medical catheter can be moved smoothly, and the phenomenon of locking is not easy to occur. Of course, the inner diameters of the first pipe body 1 and the second pipe body 2 may not be equal.

In this embodiment, the length of the reduced end 11 is equal to the length of the flared end 21, and the reduced end 11 is completely sleeved into the flared end 21, so that no gap exists at the joint of the first pipe body 1 and the second pipe body 2, and the outer surface of the medical catheter is smoother.

As shown in fig. 5, in this embodiment, the first pipe 1 and the second pipe 2 are welded together, and the first pipe 1 and the second pipe 2 are heated, so that the joint between the first pipe 1 and the second pipe 2 is welded together, thereby improving the connection strength. Of course, the first tube 1 and the second tube 2 may be fixed by adhesion.

Further, in this embodiment, the first pipe 1 and the second pipe 2 are made of the same material, and the welding strength of the first pipe 1 and the second pipe 2 made of the same material is higher.

In this embodiment, the developing ring 2 is made of platinum-iridium alloy, tantalum or gold.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
