Is the ventricular drainage tube a plasma drainage tube?

No, according to 39 Health Network, ventricular drainage tube is a medical device for treating hydrocephalus. Plasma drainage tube is a device for plasma exchange therapy. Plasma exchange is a treatment method, which separates the patient's plasma, removes the harmful substances in it, and then transfuses the plasma into the patient's body to achieve the therapeutic effect. So the ventricular drainage tube is not a plasma drainage tube.
