Problems solved by technology

[0004] When the existing hemodialysis catheter is used, one end of the tube body is exposed on the body surface, and the other end of the tube body enters the central vein by puncturing the subcutaneous tissue, which is not beautiful, and is inconvenient for bathing or swimming. Cause subcutaneous tunnel infection and affect the life of the catheter. In addition, patients are prone to skin pulling pain when they accidentally touch or pull the exposed catheter in daily life, and the catheter is prone to fall off after long-term use

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0022] like figure 1 As shown, a subcutaneous implantable hemodialysis catheter includes a catheter 1 with two independent channels. It is made of titanium alloy material or PP material. The upper end of the implant base is recessed downward to form two independent chambers. There is a partition wall 3 between the two chambers, and a pierceable diaphragm 4 is covered above the chamber. The diaphragm 4 is made of silica gel, and one side of the bottom of the implant base 2 is integrally formed with an outwardly protruding conduit connecting column 5. There are also two independent flow channels in the conduit connecting column 5, so as to be connected with the two conduits. The flow channels are matched one by one, the two flow channels of the conduit connecting column communicate with the two chambers in the implant base respectively, one end of the...

Abstract

The invention discloses a subcutaneously implanted type hemodialysis catheter. The subcutaneously implanted type hemodialysis catheter comprises a catheter body and an implanting base, wherein the catheter body is provided with two independent channels; the upper end face of the implanting base is downwardly concave to form two independent cavities, a separation wall is arranged between the two cavities, a diaphragm which can be punctured covers the cavities, an outwardly-protruding catheter connecting column is arranged on one side of the bottom of the implanting base and provided with two independent channels inside, the two channels of the catheter connecting column are respectively communicated with the two cavities of in the implanting base, the catheter body is detachably connected with the catheter connecting column, and fixing rings are further arranged on the outer side of the implanting base. The subcutaneously implanted type hemodialysis catheter is long in service life, less prone to infection and capable of preventing the catheter from being exposed on the surface of the skin.

Description

[0001] Technical field: [0002] The invention relates to a medical device, in particular to a subcutaneous implanted hemodialysis catheter. [0003] Background technique: [0004] When the existing hemodialysis catheter is used, one end of the tube body is exposed on the body surface, and the other end of the tube body enters the central vein by puncturing the subcutaneous tissue, which is not beautiful, and is inconvenient for bathing or swimming. Infection in the subcutaneous tunnel will affect the life of the catheter. In addition, patients are prone to skin pulling pain when they accidentally touch or pull the exposed catheter in daily life, and the catheter is prone to fall off after long-term use. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to provide a subcutaneous implantable hemodialysis catheter with a long service life and not easily infected. The subcutaneous implantable hemodialysis catheter can be embedded ...
