If you need to inject a lot of liquid, should be sub-injection. After the note, the left hand holding dry cotton ball hold the puncture point, right hand ** needle, local disinfection.

  Veterinary Medicine Injection Let's first look at the intravenous injection of large animals, the first routine disinfection, and then the right hand with a needle, so that the needle tip up, along the jugular vein path, at the top of the pressure point about 2 cm above the tip and skin 30 ° - 45 ° angle, quickly and accurately piercing the vein, and feel empty or hear crisp sound, see a return to the blood, with a clip will be a disposable infusion set of the needle fixed to the neck skin, liquid slowly into the vein. Next, take a look at the intravenous injection of small animals
