canula การใช้

The RF-TVA procedure is different in that a physician directs a small navigational canula into the vertebra and creates a small pathways for the cement as opposed to using a balloon.
With the canula inserted up my nose and a steady stream of Clarity-flavored oxygen whooshing into my system, I asked the manager, John Wood, whether the gas comes straight from a tank or is purified in-house.
Wood is the general manager of a trendy new " oxygen bar " on Hollywood's Sunset Strip where, for $ 13 a pop, customers are invited to insert a plastic canula tube up their noses and spend 20 minutes breathing a cocktail of " oxygen rich " air, fruit flavorings and aromatherapy oils with names like Clarity, Passion and Joy.
