Abstract
This invention provides a kind of siliconizing reagent and the siliconizing method for the pinhead. The said reagent is made of 1~5 portions of organosilicon oil dissolved in 100 portions of solvent. The used solvent can be anyone choosed from hexamethyldisiloxane, 1-fluoro-1,1-dichloroethane, dichloro-pentafluoropropane, pentafluorobutane or Techspray G 1637. The said method involves wiping the siliconizing reagent on the surface of the pinhead uniformly, drying it to volatilize the solvent and forming a thin layer of organosilicon oil on the surface of the pinhead. The used solvent is not F113, but a substitute with each physical and chemical index close to F113. The used solvent can ensure the siliconizing quality of the pinhead and its volatile has no pollution on environment. It solves a great difficulty which puzzles in the field of one-off medical appliance, and hence has significant society benefit and visible economic efficiency.
Description
Technical field
The present invention relates to a kind of surface treatment reagent and treatment process thereof of medicine equipment, particularly a kind of siliconizing reagent and siliconizing method thereof that is used for the syringe needle of entry needle, transfusion needle, blood taking needle to medical field.
Background technology
The syringe needle of the entry needle in the medical field, transfusion needle, blood taking needle is generally drawn by stainless steel pipe and forms, through after the following process, need clean, after assembling, also to carry out siliconizing to syringe needle, so that allow syringe needle form slick outside surface, reduce its frictional resistance in piercing process as far as possible.The purpose of siliconizing is to form the very thin organosilicon oil reservoir of one deck on the surface of syringe needle.But this organosilicon oil reservoir can not directly adopt organic silicone oil to smear, but organic silicone oil is dissolved in a kind of volatile solvent, form the dilute solution of organic silicone oil, and then syringe needle is immersed in for some time in this solution, allow syringe needle attach one deck solution, dry for some time, treat that volatile solvent evaporates in the solution is intact after, just stay very thin one deck organic silicone oil in needle surface, form very slick surface.Prior art generally is to adopt Freon 113 as solvent when the dilute solution of preparation organic silicone oil, and the popular name of Freon 113 is called for short F113 in fluorine Lyons 113.F113 is that as the advantage of solvent it does not burn, does not explode, and uses fool proof; It is nontoxic, good biocompatibility; It is the fine solvent of organic silicone oil, and boiling point is suitable, and is volatile, can not remain on the disposable medical equipment.Therefore, F113 has obtained widespread use in the disposable medical instrument industry.But, banned use of by more and more countries now owing to after it evaporate in the air, can produce destruction to the foul smell layer in the atmosphere.Therefore, the substitute of seeking a kind of F113 is the problem that the disposable medical instrument industry presses for solution.
Summary of the invention
Purpose of the present invention is to provide a kind of siliconizing reagent and siliconizing method thereof of syringe needle, and solvent does not wherein adopt F113, can avoid the problem of environmental pollution that uses F113 to bring.
The objective of the invention is to be achieved through the following technical solutions: a kind of siliconizing reagent of syringe needle, be characterized in, described reagent is dissolved in solvent 100 weight parts formulated by organic silicone oil 1-5 weight part, described solvent is selected from hexamethyldisiloxane, 1, a kind of among 1-two chloro-1-fluoroethanes, dichloro pentafluoropropane, 3-pentafluorobutane or the Techspray G 1637.
Described Techspray G 1637 is the mixture of dichloro pentafluoropropane, anti--1,2-dichloroethene and acetone.
A kind of siliconizing method of syringe needle is: the siliconizing reagent of syringe needle is evenly spread upon the surface of syringe needle, dry then, the solvent evaporates in the reagent is fallen, form the very thin organosilicon oil reservoir of one deck on the surface of syringe needle.
The solvent that the siliconizing reagent place of syringe needle of the present invention adopts is not F113, but all approaching substitute of every physical and chemical index with F113, under the situation of the silication quality that guarantees syringe needle, can not pollute after its volatilization environment, solve a hard nut to crack of puzzlement disposable medical instrument industry, had important social benefit and tangible economic benefit.
Every physical and chemical index of all kinds of SOLVENTS that is adopted among the present invention and F113 is as shown in table 1.
