Venous cannula is also a deep venous puncture catheter. The method is to select the appropriate puncture site and insert the needle under the skin, and insert the needle with negative pressure until the dark red blood is absorbed, indicating that the needle has entered the vein, and the guide wire is inserted. Withdraw the puncture needle to leave the guide wire in the blood vessel, and then insert the venous catheter that needs to be indwelled along the guide wire, then exit the guide wire, inject diluted heparin saline and fix the catheter, the deep venous catheterization is completed. The veins for puncture and catheterization are usually selected clinically, including the subclavian vein, internal jugular vein, and femoral vein. After the puncture catheter is indwelled, attention must be paid to the care of the puncture site to avoid infection with thrombus or catheter falling off. venous cannulation,best veins for cannulation,venous cannulation set,venous cannulation technique Yong Yue Medical Technology(Kunshan) Co.,Ltd , https://www.yonyuebio.com Name of product specification Materials Steel factory / origin Price (yuan/ton) Than yesterday Compared to last week Than last month Seamless tube Φ108*4.5 20# Balance tube 5300 0 0 0 Seamless tube Φ219*7 20# Balance tube 5200 0 0 200 Seamless tube Φ273*8 20# Balance tube 5500 0 0 100 Seamless tube Φ273*8 20# Baogang 5200 0 0 0 Welded pipe 1.5 inch Q235 Foshan 3930 0 0 180 Welded pipe 8 inches Q235 Foshan 4000 0 0 100
