Dental spray water and air delivery tube - has water tube inside air tube, projecting beyond flared end of air tube

摘要

The tube with one end at an angle and forming the delivery end of a dental spray, has an inner tube (2) for delivering water, concentrically mounted inside an outer tube (4) for delivering compressed air. At the feed end, the outer tube is closed where the inner tube (7) is attached, and has side entry holes (6) for the air. At the delivery end, the outer tube flares outwards forming a funnel (1) and the tip of the water tube projects beyond its end. This part of the water tube slopes at an angle to the axis of the final sloping end of the air tube.
