MEDICAL DEVICE HAVING INTEGRATED SEQUENCE CONTROL

摘要

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.
