The system is said to allow needles to be handled without re-tightening the screws
The LeEject 2 syringe and needle system has been approved for sale in the United States by the FDA. It is reported that this unique system protected by U.S. patents differs from conventional dental syringes and needle systems in that it allows the needle to be loaded from the side entrance and discard the needle without reattachment and unscrewing.
Insert the needle from the side and rotate the plastic sheath clockwise to fix it. The loading and unloading procedures for the anesthetic cartridge are the same as for the conventional dental syringe and needle system. It is said that the removal of the needle is very simple; by turning the guard counterclockwise and turning the syringe over the sharps container and letting the needle fall into it, this eliminates the potential risk of re-covering and unscrewing the contaminated needle.
Currently, OSHA prohibits the replacement or removal of contaminated needles and other contaminated sharps unless the employer can prove that there is no other way. Due to the lack of alternatives in the market, mechanical or one-handed techniques must be used to re-stamp or remove the needle.
It is reported that the LeEject 2 system is safe, simple and economical. Dr. DDS Dr. D. Lee has overseen the FDA’s application process for the past six years. They hope to implement marketing to dental schools, health programs, and resident sites by providing them with cost-reducing systems because inexperienced operators are more likely to cause acupuncture, hurt.
