AI Technical Summary

Benefits of technology

[0015]The primer coating or layer improves the lubrication between the relatively sliding parts. More evenly distributed lubricant might be a factor in lowering the sliding friction and making the sliding friction more uniform. As another potential result, in a medical vessel coated on the interior wall with the primer coating or layer and a deposit of lubricant, the more evenly distributed lubricant can improve draining of the vessel. As a third potential result, the more evenly distributed lubricant can be used in a smaller quantity to obtain the same technical effect or advantage, thus potentially reducing the amount of lubricant available to mix with the contents of the vessel. Some potential examples of the lubricant mixing with the contents of the vessel are mechanical or chemical emulsification of the lubricant and a drug or other contents of the vessel.
[0016]Optionally, the primer coating or layer itself, without a deposit of lubricant, can improve draining of the vessel.

Problems solved by technology

Glass pharmaceutical packages or other vessels are prone to breakage or degradation during manufacture, filling operations, shipping and use, which means that glass particulates may enter the drug.
Glass-forming processes do not yield the tight dimensional tolerances required for some of the newer auto-injectors and delivery systems.
Glass is also more difficult and expensive to fabricate into syringes than injection molded plastics.

Protocol for Coating Syringe Barrel Interior with SiOx

[0208]The apparatus and protocol generally as found in U.S. Pat. No. 7,985,188 were used for coating syringe barrel interiors with an SiOx barrier coating or layer, in some cases with minor variations. A similar apparatus and protocol were used for coating vials with an SiOx barrier coating or layer, in some cases with minor variations.

Protocol for Coating Syringe Barrel Interior with Primer Coating or Layer

[0209]Syringe barrels already interior coated with a barrier coating or layer of SiOx, as previously identified, are further interior coated with a primer coating or layer of SiOxCy as previously identified, generally following the protocols of U.S. Pat. No. 7,985,188 for applying the lubricity coating or layer, except with modified conditions in certain instances.

examples 1-3

[0221]Syringe samples 1-3, employing three different primer coatings or layers, were produced under the following PECVD conditions:[0222]OMCTS—2.5 sccm[0223]Argon gas—7.6 sccm (when used)[0224]Oxygen 0.38 sccm (when used)[0225]Power—3 watts[0226]Power on time—10 seconds

[0227]Syringe 1 had a three-component primer coating or layer employing OMCTS, oxygen, and carrier gas. Syringe 2 had a two component primer coating or layer employing OMCTS and oxygen, but no carrier gas. Syringe 3 had a one-component primer coating or layer (OMCTS only). The primer coatings or layers produced according to these working examples are contemplated to function as protective coatings or layers to increase the shelf life of the vessels, compared to similar vessels provided with a barrier coating or layer but no primer coating or layer.

examples 4-6

[0228][03] HMDSO was used as the precursor in Examples 4-6. The results are shown in Table 1. The coatings produced according to these working examples are contemplated to function as primer coatings or layers, and also as protective coatings or layers to increase the shelf life of the vessels, compared to similar vessels provided with a barrier coating or layer but no primer coating or layer.

Abstract

A syringe comprising a wall having a generally cylindrical interior surface defining a lumen with a primer coating or layer between 1 and 1000 nm thick of SiOx Cy Hz, in which x is from about 0.5 to about 2.4, y is from about 0.6 to about 3, and z is from about 2 to about 9, on at least a portion of the interior surface, the primer coating or layer having an outside surface facing the interior surface of the barrel and an inside surface facing the lumen. A deposit of fluid lubricant on the inside surface of the primer coating or layer is further provided.
