Embodiment 1

[0012] Get 5 grams of organic silicone oil and dissolve in 100 grams of hexamethyldisiloxane to obtain a siliconization treatment reagent for a syringe sleeve of the present invention, spray the reagent evenly on the inner surface of the syringe sleeve, and then dry it. The solvent in the reagent is volatilized, and a thin layer of organic silicon oil is formed on the inner surface of the syringe sleeve to complete the siliconization treatment of the syringe sleeve.

Embodiment 2

[0014] Get 10 grams of organic silicon oil and dissolve in 100 grams of 1,1-dichloro-1-fluoroethane to obtain a siliconization treatment reagent for a syringe sleeve of the present invention, and spray the reagent evenly on the inner surface of the syringe sleeve, Then dry it to evaporate the solvent in the reagent, and form a thin organic silicon oil layer on the inner surface of the syringe sleeve to complete the siliconization treatment of the syringe sleeve.

Embodiment 3

[0016] Get 15 grams of organic silicon oil and dissolve in 100 grams of dichloropentafluoropropane to obtain a siliconization treatment reagent for a syringe sleeve of the present invention, spray the reagent evenly on the inner surface of the syringe sleeve, and then dry it to make the reagent The solvent in the syringe volatilizes, and a thin layer of organic silicone oil is formed on the inner surface of the syringe sleeve, completing the siliconization treatment of the syringe sleeve.

Abstract

This invention provides a kind of siliconizing reagent and the siliconizing method for the injector sleeve. The said reagent is made of 5~20 weight portions of organosilicon oil dissolved in 100 weight 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 spraying the siliconizing reagent on the internal surface of the injector sleeve uniformly with the spray gun, drying it to volatilize the solvent and forming a thin layer of organosilicon oil on the internal surface of the injector sleeve. The used solvent is not F113, but a substitute with each physical and chemical index similar to F113. The used solvent can ensure the siliconizing quality of the injector sleeve, 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 [0001] The invention relates to a surface treatment reagent of a medical device and a treatment method thereof, in particular to a reagent for siliconizing the inner wall of a syringe sleeve in the medical field and a siliconization treatment method thereof. Background technique [0002] The inner wall of the syringe sleeve in the medical field is siliconized during the production process to form a smooth inner surface and minimize the frictional resistance of the syringe during push and pull. The purpose of siliconization is to form a thin layer of silicone oil on the inner wall of the syringe barrel. However, this silicone oil layer cannot be directly applied with silicone oil, but the silicone oil is dissolved in a volatile solvent to form a dilute solution of silicone oil, and then sprayed onto the inner wall of the sleeve with a spray gun to make the inner wall of the sleeve Attach a layer of solution and dry for a period of time. After the volatile sol...
