Abstract

About 1/2 cc of a sterile composition (5) exhausted in the supply line (11) air impeller rotor a dental handpiece (10) while the lower handpiece is retained, protects and lubricates bearings handpiece and turbine during the subsequent autoclave sterilization process. An additional dose inserted into the hole of the cavity cutter after the autoclave process also lubricates the handpiece and inhibits the rust that forms in the bearings of the handpiece and the turbine during use. The pre-sterilization dose and post-sterilization dose of measured quantities can be packaged separately in available capsules (20, 30). The composition (5) is manufactured by heating the mixture to about 10% of sterile bulk volume of a sterile solution Power-Up NNL-690, which is a lubricant in the boundary layer of liquid hydrocarbon and corrosion inhibitor, with 90% by volume of pharmaceutical grade mineral oil

Description

PIECE BY THE DENTAL HAND the HYGIENIC PHARMACEUTICAL STERILIZATION LUBRICANT BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION The present invention generally relates to a sterile, pharmaceutical composition inserted in a piece prior by the dental hand to and after sterilization lubricating moving parts and inhibiting piece corrosion by hand, and , more particularly, to the process of sterilizing things if instrumented inserting the prior of the compositions to sterilization system. a. Previous Piece Lubricant by Hand and Processes It is well known that a piece by the dental hand has to be lubricated to maintain its effectiveness and prevent premature failure periodically. The rotor or turbine in the piece by hand is supported on bearings that are subjected to severe use due to the wide range of speeds and torque loads involved by drilling teeth. Typically, the bearings are lubricated by adding oil in a variety of ways, such as from a large nipple connected to the rotor drive line of the aerial feed that intermittently drops oil into the intake air stream where the oil is atomized and then carried to the entrained of the rotor in the air of the entrance. In a method discovered in Sugai U.S. Patent 4,218,216 an improved system employed a small oiler inserted into the airline food line that has a spring loaded check valve surmounted by atmospheric food pressure to allow oil to escape into the feed air, atomized and continuously lubricates the rotor bearings . However, with the AIDS attack and the need for increased sterilization, such a system did not work during system sterilization and offered no protection against cross contamination. Through 1991, as he discovered in Feldman U.S. Patent 5,131,845, it was favorably recommended that the piece by hand frequently be sterilized, and sterilization of the piece by hand among the patients was becoming a recommended procedure. However, increased sterilization required more frequent lubrication. It was known to lubricate the piece by hand both before and after sterilization. However, the initial lubricants used pre-sterilization and post-sterilization were generally the same products as was prior previously available to the need for increased sterilization. These products did not survive the heat of the system's own sterilization process and were in effective. Piece failures by hand increased and were replaced at a unit cost of approximately $ 150.00 US While that Feldman developed an improved method of inserting oil into the rotor ride aerial food line using a capable to tighten sealed capsule containing lubricant la and its system prevented the transmission of the material from the bacterial and beyond to the patient the viral and the dentist, of the art of no of the advance of the compositions of the lubricant in ways Of which no development could only withstand the cycle of the sterilization system, but also protect the piece by hand during the sterilization cycle by retaining and / or reinforcing its limit that lubricates the characteristics of and anti-corrosion Feldman merely discovered that his shell 10 was filled with an extremely light, dental quality, FDA approved, lubricating oil that was required for the piece by hand and was widely used in the art. Feldman 7: 21-24. b. Industrial Product Condoms It was also known to add ingredients, such as, an anion selected from the group consisting of the sulfate, the acetate and citrate groups, an acidic industrial products to inhibit micro-degradation in stories and products that son the result of the growth of micro-organisms that can cause biological odors, the corrosion deterioration of y. Pear U.S. Patent 4,920,107. In an improvement to Nelson U.S. Patent 5,283,005, the efficacy of the biocidal of such additives was reinforced by mixing a known condom (pyrithione, used in lubricant) with a known antibiotic (lipopeptide, for treating superficial infections) to inhibit bacteria and fungi notably from forming in the composition itself when used exclusively or in combination with an inert carrier, such as water, liquid hydrocarbons, ethanol, isopropanol, or the like. 2: 63-67. There was no discovery or suggestion of the composition of the present invention however, that the discovered compositions were sterile or could be used as a pre-sterilization lubricant for a piece by the dental hand, or that the lubricating limit or the protective quality of the compositions was reinforced. c. Theory of Limit Lubricant The general theory of how a limit lubricant works are well known. When the surfaces warn us when rolling or sliding contact, particles of se se form of what combines of use against the lubricant to form an eutectic film (new) The point of one of has material of the lowest fusion that the original material) which can resist high charges and can become the sacrificial layer that is carried away and removed instead of being under (rotor / carrying) the material, thus, reducing friction. It is an object of the present invention to provide a new, low friction coefficient, lubricant composition and process that allow insertion of the composition in the rotor ride the prior of the air inlet to the system sterilization cycle, or after , or both, and what remains effective during the sterilization cycle system and after this to provide improved protection of the piece by hand against corrosion, substantially reduced utilization rates and substantially improved resistance leading to that by extending the service life of the piece by the hand significantly. It is an extensive objective of the present invention to provide a new sterile composition and process that reduces the risk of cross-contamination of viruses and bacteria. 2.
