Embodiment Construction

[0020] Such as Figure 1-3 As shown, a central venous catheter with anticoagulant and antibacterial functions for interventional diagnosis and treatment includes an interventional diagnosis and treatment catheter 1, a main lumen branch 2, a side lumen branch 3, a main lumen 4, a side lumen 5, three tube fixing seats 6, fixed side wings 7. Branch pipe seat 8, stop card 9, anti-backflow device 10, bio-modified coating 11. The main lumen branch pipe 2 and the side chamber branch pipe 3 are connected to the interventional diagnosis and treatment catheter 1. The interventional catheter 1 is provided with two lumens, which are respectively the main lumen 4 and the side chamber 5. The main lumen branch pipe 2 communicates with the main lumen 4, and the side chamber The lumen branch 3 communicates with the side cavity 5, and the three-tube fixing seat 6 is fixedly arranged at the junction of the interventional diagnosis and treatment catheter 1, the main lumen branch 2, and the side c...

Abstract

The invention relates to a central venous catheter for the anti-freezing antibiosis intervention diagnosis, which comprises an intervention diagnosis catheter, a main cavity branch pipe, a lateral cavity branch pipe, a main cavity, a lateral cavity, a seat for fixing three pipes, fixed lateral wings, a support pipe seat, stop fasteners, an anti-inversion device and a biomass modified coating layer. End heads of the intervention diagnosis catheter are closed, a plurality of long gaps are arranged on the upper portion of the end head of the intervention diagnosis catheter along a catheter body in the radial direction in cutting mode to form the anti-inversion device of a valve channel, and the biomass modified coating layer is permeated and grafted between tissue structure of catheter wall manufacture material silicon rubber of the intervention diagnosis catheter. Compared with the prior art, the central venous catheter greatly improves product accuracy and improves using performance.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a central venous catheter for interventional diagnosis and treatment with anticoagulation and antibacterial functions and a preparation method thereof. Background technique [0002] At present, commonly used venous catheters for medical interventional diagnosis and treatment generally have problems such as blood clots leading to thrombus, phlebitis, and bacterial infection. The incidence of catheter-related infection gradually increases with the prolongation of catheter indwelling time. After 24-48 hours of catheter indwelling, a fibrin sheath surrounds the catheter, and microorganisms can multiply in it. The longer the catheter is indwelling, the higher the bacterial reproduction rate . Clinically, there is an urgent need for a treatment method that can effectively reduce coagulation to increase the indwelling time of interventional diagnosis and treatment catheters, reduce pain ...
