Problems solved by technology

[0002] Clinically, deep venous catheters are mainly used for rehydration and medication in critically ill patients and perioperative patients. However, the catheterization time should not be too long, which will increase the risk of infection and thrombus. Generally, it must be replaced within 5-14 days depending on the puncture site. The puncture catheter itself is an invasive operation, and frequent replacement will increase the risk of bleeding and infection for patients

Abstract

The invention provides a nanometer double-resisting deep venous catheter. The deep venous catheter is characterized by comprising a deep venous catheter body; wherein the deep venous catheter body is composed of a deep venous catheter main body, a deep venous catheter outer sustained-release layer and a deep venous catheter inner sustained-release layer; the deep venous catheter main body is provided with a through pipeline; the deep venous catheter outer sustained-release layer is located on the outer surface of the deep venous catheter main body; the deep venous catheter inner sustained-release layer is located on the inner surface of the deep venous catheter main body; the deep venous catheter outer sustained-release layer is used for slowly releasing drugs with anti-infection and / or antithrombotic effects; and the deep venous catheter inner sustained-release layer is used for slowly releasing drugs with anti-infection and / or antithrombotic effects. The deep venous catheter can resist infection and thrombus, has dual functions, can prolong the catheter indwelling time, and can reduce the damage to the body of a patient by reducing the infection and thrombus formation of the patient.

Description

Technical field [0001] The present invention relates to a medical device, and more particularly to a nano-dual anti-depth venous catheter. Background technique [0002] The clinical deep venous catheter is mainly used in critically ill patients and perioperative patients, but the tube time should not be too long, there will be the risk of increasing infection and thrombosis, generally replaced according to the difference of 5-14 days depending on the puncture site. The puncture tube itself is creative operation, often replacing the risk of patient bleeding and infection. Inventive content [0003] The present invention is intended to overcome the above defects, providing a venous catheter that is capable of infection, and anti-thrombus, which can not only extend the tube time, but also reduce patient infection and thrombosis. Reduce damage to the patient's body. [0004] The present invention provides a nano-dual anti-deep venous catheter, characterized in that: comprising a dee...
