Medical coupling device
First Claim
1. A medical coupling device for transferring a fluid between a first reservoir and a second reservoir having a slit-less diaphragm, comprising:
- a connector having a port; and
a blunt cannula in fluid communication with the port and adapted to puncture and sealingly engage the diaphragm and thereby transfer fluid between the first reservoir and the second reservoir.

Abstract
A medical coupling device is provided which is used for transferring fluid between a first reservoir and a second reservoir having a slit-less diaphragm. The device includes a connector having a port and a blunt cannula in fluid communication with the port. The cannula is adapted to puncture the diaphragm on the second reservoir and thereby facilitate the transfer of fluid between the first reservoir and the second reservoir. The cannula can be a hollow tube having an end which is substantially perpendicular to an axis extending longitudinally through the tube. The device may further include a shroud of a predetermined configuration associated with the connector. The shroud defines a recess for receiving the reservoir and inhibits inadvertent contact with the cannula which extends within the recess. The shroud defines a suction opening which tends to inhibit the formation of an undesirable suction upon removal of the reservoir. The shroud also defines a tapered sidewall which facilitates alignment of the reservoir with the cannula and guides the cannula into contact with the diaphragm.

22. A medical coupling device for transferring a fluid between a first reservoir and a second reservoir having a slit-less diaphragm, comprising:
-
a connector having a port; a blunt cannula of between 14 and 30 gauge in fluid communication with the port and adapted to puncture and sealingly engage the diaphragm and thereby transfer fluid between the first reservoir and the second reservoir; and a shroud defining a recess for receiving the second reservoir, and a suction opening, the shroud further being associated with the connector and having a tapered sidewall for aligning the second reservoir with the cannula and guiding the cannula into contact with the diaphragm.
