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.yonyuepcr.com Name of product specification Materials Steel factory / origin Price (yuan/ton) Than yesterday Compared to last week Than last month altitude Φ6.5mm Q235 Angang 3050 0 0 10 altitude Φ8mm Q335 Beitai 3050 0 0 10 Rebar Φ12mm HRB335 Beitai 3130 0 0 110 Rebar Φ12mm HRB335 Ling Gang 3150 0 0 130 Rebar Φ16-25mm HRB335 New Fushun Steel 3050 0 0 100 Rebar Φ16-25mm HRB335 Beitai 3030 0 0 80 Rebar Φ16-25mm HRB335 Ling Gang 3050 0 0 150 Hot rolled coil 2.0mm*1250*C Q235 Anshan Iron and Steel (1700) 4500 0 0 100 Hot rolled coil 2.5mm*1250*C Q235 Anshan Iron and Steel (1700) 4220 0 0 120 Hot rolled coil 3.0mm*1500*C Q235 Anshan Iron and Steel (1780) 4180 0 0 130 Hot rolled coil 3.0mm*1250*C Q235 Anshan Iron and Steel (1700) 4180 0 0 130 Hot rolled coil 5.5mm*1500*C Q235 Anshan Iron and Steel (1700) 3980 0 0 160 Cold rolled plate 1.0mm*1000*2000 Q195 Angang 4950 0 0 0 Cold rolled plate 1.5mm*1000*2000 Q195 Angang 4900 0 0 0 Cold rolled plate 2.0mm*1000*2000 Q195 Angang 4900 0 0 0 Puzhong board 8mm Q235 Angang 4200 0 0 100 Puzhong board 20mm Q235 Angang 4000 0 0 200 Puzhong board 20mm Q235 Tianzhong 3850 0 0 350 Low alloy plate 6mm Q345 Angang 4850 0 0 100 Low alloy plate 8mm Q345 Angang 4400 0 0 100 Low alloy plate 20mm Q345 Angang 4150 0 0 150 Checkerboard 3.5mm*1250*6000 Q235 Angang 4330 0 0 80 Checkerboard 4.5mm*1250*6000 Q235 Angang 4330 0 0 80 Checkerboard 5.5mm*1250*6000 Q235 Angang 4330 0 0 80 Checkerboard 6.5mm*1250*6000 Q235 Angang 4330 0 0 80 Seamless tube 76mm*4.5 20# Angang 4550 0 0 0 Seamless tube 108mm*4.5 20# Angang 4450 0 0 0 Seamless tube 113mm*4.5 20# Angang 4450 0 0 0 I-beam 12# Q235 A Gang 3400 0 0 0 I-beam 25# Q235 Angang 3480 0 0 50 Channel steel 16# Q235 A Gang 3200 0 0 150 Channel steel 25# Q235 Rolling 3350 0 0 50 Angle Steel 50*5mm Q235 Tong Gang 3120 0 0 0 Angle Steel 80*8mm Q235 Tong Gang 3150 0 0 0
