摘要:
Prefilled, disposable syringes for injecting preparations with a fill volume of less than 5 ml are typically made of glass. The disposable syringe in this invention avoids the use of glass as a construction material. The body of the syringe with barrel, grip and nozzle is made of transparent, glass-like plastic with a very low gas permeability and is designed to be resistant to gamma rays and/or ethylene oxide gas, whereby the hypodermic needle is directly integrated within the plastic nozzle.

The invention concerns a container for injection, infusion, and diagnostic preparations, serving, on the one hand, as a long-term storage container, and, on the other, as a device for directly dispensing the preparations. The container has a glass barrel with a glass headpiece with a connector cone that acts as a nozzle. This is molded onto a glass barrel, thereby forming a single unit. A separate plastic, threaded section of an interlocking, conical joint is mounted onto the connector cone, accommodating a secured sealing cap that can be removed from the connector cone. The other opening of the glass barrel is sealed by a plunger that has a connection spot for a plunger rod. Furthermore, the container has a plastic grip mounted onto the inner wall of the glass barrel. Since the container, including the external profile, is, on the whole, designed to resemble a standard syringe, it ensures that the invented container can be accommodated by all current syringe pumps.

The invention is a medicament magazine having at least one medicament chamber for use in a powder inhaler, wherein the magazine is formed from two foil strips applied to one another and the at least one medicament chamber is formed between the foil strips as depicted in exemplary FIGS. 1a and 1b. The medicament chambers have an internal structure (3) which comprises in its interior a space for receiving a powdered medicament and stabilizes this inner space against external mechanical influences. In another embodiment in which the internal structure preferably also has a stabilizing function, the structure has means for opening one foil strip. In addition, the medicament chamber contains a retaining device which holds the internal structure on the medicament magazine after the medicament chamber has been opened.

The invention is a glass container which can be sterilized for medical purposes, including the storage of pharmaceutical or diagnostic products, further including solutions. The container is made from glass containing a stabilizer which inhibits the deleterious effects of high energy radiation, wherein the surface which is in direct contact with the product or solution has a coating that has a thickness of less than 400 nm and is formed from oxides or nitrides of the elements Si, Ti, Ta, AI or a mixture thereof.
摘要:
A method for manufacturing a filled syringe body within a single continuous manufacturing line in a self-contained environment with controlled conditions. The method includes the steps of injection molding the syringe body, sealing the one end of the syringe body, siliconizing the barrel of the syringe body, filling it, sealing the other end of the syringe, and sterilizing it. With this new "injection mold-fill-seal" method, a syringe body can be manufactured as a mass-produced article in one manufacturing line in an inexpensive manner.
摘要:
A fully assembled dual chamber prefillable syringe cylinder for the administration of two components having a syringe barrel which, in both its single cylinder and dual chamber cylinder embodiments, is connected to both a syringe head featuring a tip cap as well as to the finger grips and which is closed at its base by means of a moveable plunger with a plunger rod and into which an intermediate plunger is positioned with the intent of separating first and second chambers from each other and which features a bypass located in a first chamber, as well as to a method for the manufacture and filling of said fully assembled prefillable syringe.
