Connection arrangement and method for connecting a medical device to the improved connection arrangement
First Claim
1. A connection arrangement for providing at least a first medical device with a substantially tamper resistant connection, said connection arrangement comprising;
- a first connection member for connection to said at least one first medical device;
a second connection member having a membrane coupling having at least one guiding groove;
a body having a lock flange extending around the periphery of the body;
a supportive housing having a wedge protrusion;
wherein said first connection member and said body are connected via at least one designated ruptureable retaining member that is integrally formed with the body and a cylinder of the first connection member and is arranged to rupture when subjected to a predetermined breaking force, andwherein said first connection member, and thereby said first medical device after assembly, can be displaced with respect to said body after rupture.

Abstract
The present invention relates to a connection arrangement and a method of assembly, for providing a substantially tamper resistant connection with at least a first medical device. The connection arrangement having a center axis, the connection arrangement comprises; a first connection member for connection to the first medical device by means of a rotational motion in a first direction, and a body. Additionally the first connection member and the body are connected directly or indirectly together via at least one designated ruptureable retaining member, the designated ruptureable retaining member is arranged to rupture at a predetermined breaking force, wherein the first connection member, and thereby the first medical device after assembly, can be displaced with respect to the body after rupture. The present invention provides for a substantially tamper safe connection arrangement which disables accidents such as wrongly disengage a connected medical device. A safer handling is provided for the involved user(s).

20. A method for attaching a first medical device to a connection arrangement to form a substantially tamper resistant connection there between, said method comprising the steps of;
-
attaching said first medical device to a first connection member of said connection arrangement by moving in a first direction; rupturing at least one designated ruptureable retaining member which is integrally formed with the first connection member and a body of said connection arrangement in a fixed position, by subjecting said designated ruptureable retaining member to a predetermined breaking force, so that a supportive housing permits said first connection member and said body to be displaced around a centre axis with respect to each other. - View Dependent Claims (21)

22. A female or a male coupling device having a centre axis A for connection with at least a first medical device, said coupling device comprising a connection site comprising;
-
a cylinder member having threads for providing a threaded coupling with a first medical device by means of a rotational motion in a first direction, said cylinder member comprising an inner and an outer surface, a fluid transfer channel for enabling a fluid connection, wherein said cylinder member is arranged to at least partly encompass said fluid transfer channel, and a body having a lock flange extending around the periphery of the body, and a supportive housing having a wedge protrusion, said fluid transfer channel extending inside of said body, wherein said cylinder member is connected to said body via at least one designated ruptureable retaining member integrally formed with the body and the cylinder, wherein said at least one designated ruptureable retaining member is arranged to rupture at a predetermined breaking force whereafter said supportive housing permits said cylinder member to freely rotate around said centre axis (A) and with respect to said body. - View Dependent Claims (23, 24, 25, 26, 27, 28)
