Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-4, the utility model provides a catheter fixer, including protection casing 1, fixed bottom ring 2 and elasticity mouth of pipe cover 3, elasticity mouth of pipe cover 3 is fixed in the trompil department in the pipe hole of protection casing 1, and the diameter of fixed bottom ring 2 is corresponding with the cover mouth diameter of protection casing 1, covers in cover mouth edge, with cover mouth fixed connection, and fixed bottom ring 2 pastes and covers tie coat 4. The catheter fixer can fix the hemodialysis catheter 10, isolate the contact between the human body insertion part and the external environment, and effectively prevent the infection of the insertion part.

Wherein, tie coat 4 adopts prior art's medical gluing agent, and medical gluing agent among the prior art divide into: the adhesive for soft tissue is suitable for use in replacing needle to suture skin wound and incision for hemostasis and anastomosis of operation incision without obvious scar. Can also be used for the adhesion of the internal liver and hemostasis; the adhesive for hard tissues is suitable for bone repair, artificial hip joint and bone, and is used for filling and treating decayed teeth and adhering dentin; the medical pressure-sensitive adhesive is used for covering and protecting various surgical incisions and trauma wounds, and is used for medical pressure-sensitive adhesive tapes, surgical films, incision adhesive tapes and the like. In the utility model, the adhesive layer 4 is a medical pressure-sensitive adhesive product with excellent viscosity and peel strength on skin of 0.8-2.0N/2.5cm, so that the protective cover 1 is not easy to drop. Meanwhile, in order to further prevent the protective cover 1 from falling off, the wall thickness of the protective cover 1 is made as thin as possible, or a medical polyurethane material with low density is adopted.

The fixed bottom ring 2 is adhered with the adhesive layer 4, the protective cover 1 is tightly adhered on the skin, the human body part is uneven due to the internal jugular vein and the femoral vein at the position where the hemodialysis catheter is placed, and the preferable material of the fixed bottom ring 2 is a rubber material so as to adapt to different human body parts; to facilitate viewing of the insertion, the material of the shield 1 is transparent.

The elastic pipe orifice sleeve 3 is of a circular truncated cone structure, the sleeve body inner cavity 5 of the elastic pipe orifice sleeve 3 is of a cylindrical structure, and in order to further improve the fixing effect, the outer wall of the elastic pipe orifice sleeve 3 is connected with a reinforcing ring 8 through threads 7, the elastic pipe orifice sleeve is made of rubber, and the reinforcing ring 8 is made of resin.
