Dental syringe tip and adaptor |
摘要 |
Various adaptors are used for securing a replaceable syringe tip in operative relationship to a handpiece body. The syringe tip is mounted on a tapered male connector set in the hollow interior of the adaptor. O ring seals and a metal flange member are used to prevent the leakage of air or water passing from the handpiece into the interior of the adaptor and then into the syringe tip. A captivated thumb nut is utilized to prevent the thumb nut from accidently disengaging completely from the adaptor. When the thumb nut is loosened to replace a syringe tip, the thumb nut will remain captivated on the adapter, only loosening enough to allow removal and insertion of a syringe tip.
