Abstract
Abstract An infusion device for medical purposes is described, comprising a container (10) with at least two chambers (14, 16), with their openings (20, 22) closable by means of sealing stoppers, in particular by a common stopper (12). The sealing stopper has a cavity (34) in the area of the opening (20) of the first chamber (14) which communicates with the second chamber (16). A cannula (42) may be pierced through the stopper (12) in the area of the opening (20) of the first chamber (14) and can simultaneously receive infusional solutions from the two chambers through two orifices (44, 46) spaced longitudinally from one another. The connection between the cavity (34, 40) in the stopper (12) may be established in one embodiment by means of a connecting cannula (56) with orifices (58, 60).

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
131 words
An infusion device which is adapted to receive a penetrating cannula for simultaneously infusing a plurality of liquids, comprising: a container having an orifice on the side which is the underside in the operational position, at least first and second chambers therein for holding a plurality of infusion liquids and first and second openings connecting said first and second chambers with said orifice; and a stopper member for inserting into said orifice and sealing said orifice as well as sealing said first and second openings from one another, said stopper member including therein a cavity which lies in the path of a penetrating cannula and which is adapted to provide codispensing communication between said first and second chambers upon insertion of a penetrating cannula for codispensing said plurality of infusion liquids.
Claim 2
Dependent Claim
131 words
An infusion device which is adapted to receive a penetrating cannula for simultaneously infusing a plurality of liquids, comprising: a container having an orifice on the side which is the underside in the operational position, at least first and second chambers therein for holding a plurality of infusion liquids and first and second openings connecting said first and second chambers with said orifice; and a stopper member for inserting into said orifice and sealing said orifice as well as sealing said first and second openings from one another, said stopper member including therein a cavity which lies in the path of a penetrating cannula and which is adapted to provide codispensing communication between said first and second chambers upon insertion of a penetrating cannula for codispensing said plurality of infusion liquids.
Claim 3
Dependent Claim
63 words
An infusion device according to claim 1, wherein said cavity in said stopper member is normally in communication with said first chamber and is normally sealed from said second chamber but lies in the path of a penetrating cannula into said second chamber, whereupon by insertion of a penetrating cannula into said second chamber communication is achieved between said first and second chambers.
Claim 4
Dependent Claim
62 words
An infusion device according to claim 1, wherein said cavity in said stopper member is normally sealed from both said first and second chambers but lies in the path of a penetrating cannula into both of said chambers, whereupon communication is achieved between said first and second chambers by insertion of a penetrating cannula into both of said first and second chambers.
Claim 5
Dependent Claim
49 words
An infusion device according to claim 1, 2 or 3, further comprising a first penetrating cannula inserted through said stopper member into said second chamber and intersecting said cavity, said first cannula including a first aperture opening into said second chamber and a second aperture opening into said cavity.
Claim 6
Dependent Claim
31 words
An infusion device according to claim 4, wherein said first and second apertures are each connected with a separate passageway in said first cannula for separately codispersing said plurality of liquids.
Claim 7
Dependent Claim
52 words
An infusion device according to claim 4, wherein said first and second apertures are interconnected with each other, and wherein said device further comprises a second penetrating cannula inserted through said stopper member into said first chamber and intersecting said cavity, said second cannula including a first aperture opening into said cavity.
Claim 8
Dependent Claim
49 words
An infusion device according to claim 6, wherein said second cannula includes a second aperture opening into said first chamber and wherein said first and second apertures of said second cannula are each connected with a separate passageway in said second cannula for separately codispensing said plurality of liquids.
Claim 9
Dependent Claim
27 words
An infusion device according to claim 1, further comprising a metering valve interposed in the connecting channel connecting said first and second apertures in said first cannula.
Claim 10
Dependent Claim
41 words
An infusion device according to claim 8, wherein said metering valve comprises a perforated disk, rotatable in a plane perpendicular to the connecting channel, with orifices of different diameters, said orifices being displaceable selectively into the path of the connecting channel.
Claim 11
Dependent Claim
22 words
An infusion device according to claim 6, wherein said first and second cannulas include ventilation channels entering said first and second chambers.
Claim 12
Dependent Claim
16 words
An infusion device according to claim 10, wherein each said ventilation channel comprises an air filter.
Claim 13
Dependent Claim
27 words
An infusion device according to claim 6, further comprising a metering valve interposed in the connecting channel connecting said first and second apertures in said first cannula.
Claim 14
Dependent Claim
41 words
An infusion device according to claim 12, wherein said metering valve comprises a perforated disk, rotatable in a plane perpendicular to the connecting channel, with orifices of different diameters, said orifices being displaceable selectively into the path of the connecting channel.
Claim 15
Dependent Claim
19 words
An infusion device according to claim 4, wherein said first cannula includes a ventilation channel entering said second chamber.
Claim 16
Dependent Claim
16 words
An infusion device according to claim 14, wherein each said ventilation channel comprises an air filter.
Claim 17
Dependent Claim
44 words
An infusion device according to claim 1, wherein said openings of said chambers are arranged adjacent to each other and may be closed with a common stopper member, said stopper member having at least one bung-like projection for insertion into one of said openings.
