摘要:
The present invention relates to a coating system, in particular to a coating system for articles where plastic materials slide against flexible rubber materials. The coating system is a silicone oil based coating having a viscosity of at least 200,000 centistokes, i.e. a high viscosity coating. The coating comprises in a preferred embodiment a silicone oil based block or graft copolymer, or segmented copolymer. Further the invention relates to a process of producing a component of an article coated as described above, comprising adding the coating material to the component material prior to molding and subsequently molding the component from the mixture, or molding the component from the component material and subsequently applying the coating material to the at least one surface of the component, as well as an article coated with a silicone oil based coating as defined above. Such an article is preferably a medical article, such as a container or an injection cylinder and a stopper. The coatings according to the present invention are especially suited to use for permanently coating internal surfaces of containers equipped with stoppers for storage and administration of liquid protein preparations. The coatings providing low friction between the two components, such as a container wall and a rubber stopper, result in high-precision dosing. The described coatings are particularly useful for coating containers for storage and administration of liquid protein solutions, such as insulin formulations.
摘要:
The present invention relates to a medical article for containing a pharmaceutical protein preparation comprising at least a first component and a second component, having at least one surface coated with a coating to reduce the friction between the two components and to reduce the protein adsorption to the coating. The coating is a hydrophilic coating whereby the hydrophilicity of the surface of the coating as measured by the water contact angle is below 90°, and the long term static friction forces between the first and the second component are below 14 N. The coatings according to the present invention are especially suited for permanently coating in ternal surfaces of containers equipped with stoppers for storage and administration of liquid protein preparations, such as insulin preparations. The coating is preferably a silicon-containing coating, such as a poly(dialkyl siloxane) oil or copolymer. The invention further relates to a process of producing a component of a medical article coated as described above, comprising adding the coating material to the component material prior to molding and subsequently molding the component from the mixture, or molding the component from the component material and subsequently applying the coating material to the at least one surface of the component, and hydrophilizing the coating material prior to the molding or after the molding. Also the invention relates to a coating as defined above for articles having at least a first component and a second component.
摘要:
A medicament container for storing a liquid medicament, such as insulin, comprises a wall with at least two opposite portions made of a polymer material having a light transmission at 400 nm of at least 25%, a glass transition temperature above 50° C., and a density of 0.95 g/cm3 or more. The polymer material comprises at least 70% by weight of a copolymer material composed of aliphatic cyclic or bicyclic hydrocarbons with 5 to 7 membered ring or rings and ethylene or propylene. The container is substantially inert to the medicament and, because it is either transparent or at least includes at least two opposed transparent portions, it is possible visually to inspect the contents of the container to make sure that the medicament has not crystalized or polymerized. The walls of the container provide a good barrier against m-cresol/phenol/benzyl alcohol preservatives and water.

摘要:
In an ampoule for a medicament the space accommodating the medicament is defined by an ampoule wall (1) a pierceable seal (5) closing one end of the ampoule and a piston (7) closing the other end of the ampoule. A metal containing fixation element (8) is secured to one of the parts defining the medicament accommodating space. A mixing element (9, 10) also containing a metal and having a density larger than 1,0 g/cm.sup.3 is movable in medicament accommodating space. At least one of the elements, the fixation element (8) and the mixing element (9, 10), can be attracted by a magnet, and at least one of these elements is a magnetic element, the magnetic strength being so that the mixing element (9, 10) can during normal handling of the ampoule be fixed relative to this ampoule by the magnetic attraction between the fixation element (8) and the mixing element (9, 10) but may be released from its fixed position by manual operation.

摘要:
A medicaments, container for storing a liquid medicament comprising one or more active medicaments, water and at least one preservative has a preferably cylindrical wall defining an interior space for such liquid medicament. The wall includes at least two opposed portions composed of a polymer material with a thickness of between 0.3 mm and 3 mm, a light transmission at 400 nm of 25% or more measured through the opposed container wall portions when the container is filled with water, using a standard spectrophotometer and air as reference. The polymer wall portions are of a material comprising at least 70% by weight of a linear optionally branched polyolefin material, the olefin monomer being selected from ethylene, propylene, butylene or a mixture thereof The polyolefin material has a crystallinity above 35% by weight, measured by differential scanning calorimetry, by cutting pieces from the container walls and heating them in an aluminum pan from 10.degree. C. to 270.degree. C. at the scanning rate of 10.degree. C./min, recording and integrating the melting endotherms, and using the value of 209 J/g for 100% crystalline polypropylene as a reference.
