Abstract
Abstract A device for providing fluid communication between two sealed vessels to allow the contents of the vessels to be mixed together in one of the vessels without having to break the seal. The device is particularly useful in the medical field where it is extremely important to maintain a sterile environment when mixing substances together. The device comprises two cannula members disconnectably attached to each other, one of the cannula members being insertable into one of the vessels through the sealed opening thereof and the other of the cannula members being insertable in the other of the two vessels through its sealed opening. Each of the two cannula members comprises an air passageway and a liquid passageway. The liquid passageways of the two cannula members communicate with each other to provide a means of fluid communication between the two vessels. Further, after the ingredients of the two vessels have been mixed together in one of the vessels, the fluid passageway of the cannula member associated with that vessel provides a means for withdrawing the mixture therefrom. A plug is attached to the cannula member of the vessel containing the mixture to close the fluid passageway therein when the vessel containing the mixture is stored.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
130 words
A device for providing fluid communication between two sealed vessels, comprising: a first cannula member, said first cannula member having an air passageway and a liquid passageway, said passageways extending longitudinally wherein one end of said air passageway is longitudinally displaced from the corresponding end of said liquid passageway; a second cannula member, said second cannula member having an air passageway and a liquid passageway, said passageways of said second cannula member extending longitudinally wherein one end of said air passageway is longitudinally displaced from the corresponding end of said liquid passageway; means for removably connecting said first cannula member to said second cannula member with said liquid passageways in registry whereby the liquid passageway of said first cannula member communicates with the liquid passageway of said second cannula member.
Claim 2
Independent Claim
130 words
A device for providing fluid communication between two sealed vessels, comprising: a first cannula member, said first cannula member having an air passageway and a liquid passageway, said passageways extending longitudinally wherein one end of said air passageway is longitudinally displaced from the corresponding end of said liquid passageway; a second cannula member, said second cannula member having an air passageway and a liquid passageway, said passageways of said second cannula member extending longitudinally wherein one end of said air passageway is longitudinally displaced from the corresponding end of said liquid passageway; means for removably connecting said first cannula member to said second cannula member with said liquid passageways in registry whereby the liquid passageway of said first cannula member communicates with the liquid passageway of said second cannula member.
Claim 3
Dependent Claim
83 words
A device as defined in claim 1, wherein: said liquid passageway of said first cannula member has an opening to the wall of said first cannula member and another opening to said means for removably connecting said first cannula member to said second cannula member; and said liquid passageway of said second cannula member has an opening to the wall of said second cannula member and another opening to said means for removably connecting said first cannula member to said second cannula member.
Claim 4
Dependent Claim
71 words
A device as defined in claim 1, wherein said means for removably connecting said first cannula member to said second cannula member comprises: an open cavity defined in one of said cannula members; and an extension member complementary in shape to said open cavity, projecting from the other of said cannula members, said extension being received in said cavity to removably connect said first cannula member to said second cannula member.
Claim 5
Dependent Claim
66 words
A device as defined in claim 3, wherein: said defined passageway in said other cannula member opens to said means for removably connected said first and second cannula members at the free end of said extension; and said liquid passageway in said one cannula member opens to said means for removably connecting said first and second cannula members at the bottom wall of said open cavity.
Claim 6
Dependent Claim
38 words
A device as defined in claim 4, wherein: said extension member is generally frusto-conical in shape tapering outwardly from said other cannula member; and said cavity is generally frusto-conical in shape tapering inwardly of said other cannula member.
Claim 7
Dependent Claim
101 words
A device as defined in claim 1, further comprising: a first flange connected to and disposed around said first cannula member proximate one end thereof, the plane of said first flange being generally perpendicular to the longitudinal axis of said first cannula member; and a second flange connected to and disposed around said second cannula member proximate one end thereof, the plane of said second flange being generally perpendicular to the longitudinal axis of said second cannula member, such that when said first and second cannula members are connected together said first and second flanges are disposed in relative abutting juxtaposition.
Claim 8
Dependent Claim
126 words
A device as defined in claim 1, wherein: said first cannula member further comprises one pointed end; said air passageway in said first cannula member has an opening to the wall of said first cannula member proximate said pointed end; said air passageway in said first cannula member has another opening to the wall of said first cannula member spaced from said first mentioned opening; said second cannula member further comprises one pointed end; said air passageway in said second cannula member has an opening to the wall of said cannula member proximate said pointed end; and said air passageway in said second cannula member has another opening in said cannula member to the wall of said second cannula member spaced from said first mentioned opening.
Claim 9
Dependent Claim
45 words
A device as defined in claim 7, further comprising: a filter media disposed over said other opening of said air passageway of said first cannula member; and a filter media disposed over said other open end of said air passageway of said second cannula member.
Claim 10
Dependent Claim
47 words
A device as defined in claim 7, wherein: said liquid passageway of said first cannula member is inclined to the longitudinal axis of said first cannula member; and said liquid passageway of said second cannula member is inclined to the longitudinal axis of said second cannula member.
Claim 11
Dependent Claim
23 words
A device as defined in claim 1, further comprising means for selectively opening and closing said liquid passageway in said second cannula member.
Claim 12
Dependent Claim
63 words
A device as defined in claim 3, further comprising: a plug having a shape complementary to said open cavity, and being selectively insertable into said cavity; and a flexible strap connected at one of its ends to said cannula member having said cavity, and connected at its other end to said plug thereby connecting said plug to said cannula member having said cavity.
Claim 13
Dependent Claim
