Embodiment Construction

[0051] Where relative expressions such as "upward" and "downward" are used in the following relative expressions, these refer to the drawings and not necessarily to actual usage situations. The shown figures are schematic diagrams, for which the configuration of the different structures as well as their relative dimensions are intended for illustrative purposes only.

[0052] figure 1 is an exploded perspective view of a mixing device 1 for reconstituting a powder drug in a vial 20 using solvent from a syringe 10 . The vial 20 includes a wall 21 having an opening bounded by a vial stop 23 (see figure 2 ) and sealing cap 22 seals. The tower 25 projects axially from the sealing cap 22 in a direction away from the vial 20 . The tower 25 has at its end portions an inner circumferential sealing rim 26, the purpose of which is explained below.

[0053] The vial 20 is arranged in a vial protector 2 for protecting the vial 20 . In the disclosed embodiment, the wall 21 is made of...

Abstract

The present invention relates to a medical device comprising a base member (2), a container (20) comprising a container interior (28) adapted to accommodate a substance, and a container closure (23) for fluidly sealing the container interior, and fluid connection means (50) for establishing fluid connection to the container interior. A cover (4) removably mountable on a cover receiving portion (36) is operatively coupled with the fluid connection means (50) to cause a relative motion between the fluid connection means (50) and the container closure (23) in response to a relative motion between the cover (4) and the base member (2). The medical device further comprises a cover engagement mechanism (9, 37, 46, 49) configured to prevent movement of the cover in a dismounting direction relative to the cover receiving portion when the cover and the base member are in a first relative position in which the fluid connection means (50) and the container interior (28) are fluidly separated and to allow movement of the cover (4) in a dismounting direction relative to the cover receiving portion (36) when the cover and the base member are in a second relative position in which the fluid connection means and the container interior are fluidly connected.

Description

technical field [0001] The present invention relates to fluid transfer devices, and more particularly to medical mixing devices. Background technique [0002] In drug delivery, it can be very important to maintain sterility of the product to be administered from its manufacture to its administration. Many drug substances are therefore supplied in sealed containers having penetrable access means, such as rubber septa, adapted to be pierced by a suitable implement, such as a hollow needle. [0003] For example, people with IDDM typically attach an injection needle to their insulin pen, piercing the self-sealing rubber septum of the cartridge containing the insulin, and creating a delivery line for subcutaneous administration. Needles and insulin are stored in a corresponding sterile environment until connection is made. [0004] Some drugs suitable for parenteral administration are only stable for short periods of time in an administrable form. For reasons of convenience an...
