Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
102 words
A device for facilitating the transfer of the contents of a tubular receptacle to at least a pair of successive fluid suction members, each suction member having a suction chamber and a stem communicating with the chamber, the receptacle having an open end sealably closed by an injectable closure, comprising: a cannula adapted to pierce the closure and having a passaway adapted to pass a suction member stem through the closure to vent the interior of the receptacle to the atmosphere, the cannula having an outer shroud adapted to slide over the open receptacle end closure to guide the cannula during piercing.
Claim 2
Independent Claim
102 words
A device for facilitating the transfer of the contents of a tubular receptacle to at least a pair of successive fluid suction members, each suction member having a suction chamber and a stem communicating with the chamber, the receptacle having an open end sealably closed by an injectable closure, comprising: a cannula adapted to pierce the closure and having a passaway adapted to pass a suction member stem through the closure to vent the interior of the receptacle to the atmosphere, the cannula having an outer shroud adapted to slide over the open receptacle end closure to guide the cannula during piercing.
Claim 3
Dependent Claim
14 words
A device of Claim 1 wherein the cannula is formed of a rigid plastic.
Claim 4
Dependent Claim
26 words
A device of Claim 2 wherein the cannula has a tip which is formed at an angle to define a sharp tip for piercing the closure.
Claim 5
Dependent Claim
12 words
A device of Claim 2 wherein the cannula and shroud are integral.
Claim 6
Dependent Claim
25 words
A device of Claim 1 wherein the cannula has a tip which is formed at an angle to,define a sharp tip for piercing the closure.
Claim 7
Dependent Claim
28 words
A device of Claim 1 wherein the shroud has an inside diameter greater than the outside diameter of the closure to facilitate expansion of the closure during piercing.
Claim 8
Dependent Claim
27 words
A device of Claim 1 wherein the shroud has a lower end with an internal flange adapted to engage lightly the closure for positioning prior to piercing.
Claim 9
Dependent Claim
14 words
A device of Claim 7 wherein the cannula is formed of a rigid plastic.
Claim 10
Dependent Claim
28 words
A device of Claim 1 wherein each fluid suction member is a pipette having an integral hollow bulb and connected hollow stem constructed of a flexible plastic material.
Claim 11
Dependent Claim
20 words
A device of Claim 9 wherein one of the pipette stems has a length less than that of the receptacle.
Claim 12
Dependent Claim
26 words
A device of Claim 10 wherein the other one of the pipette stems has a length at least as long as the receptacle and closure together.
Claim 13
Dependent Claim
11 words
A device of Claim 9 wherein the stems have rounded ends.
Claim 14
Dependent Claim
25 words
A device of Claim 1 wherein the cannula is positioned a-axially of the shroud in a position opposite that of the point of the cannula.
Claim 15
Independent Claim
147 words
A method for transferring the contents of a tubular receptacle to at least a pair of successive fluid suction members, each suction member having a suction chamber and a stem communicating with the chamber, the receptacle having an open end sealably closed by an injectable closure, using a transfer device having a cannula whose passageway is adapted to pass a suction member stem and an outer shroud adapted to fit over the receptacle closure comprisng the steps of: fitting the shroud over the closure, piercing the closure with the cannula while being guided by the shroud to permit access to the interior of the receptacle, inserting one of the suction members into the receptacle through the cannula, withdrawing fluid from the receptacle into the one suction member, removing the one suction member from the receptacle, and filling a second suction member from the receptacle through the cannula.
Claim 16
Independent Claim
147 words
A method for transferring the contents of a tubular receptacle to at least a pair of successive fluid suction members, each suction member having a suction chamber and a stem communicating with the chamber, the receptacle having an open end sealably closed by an injectable closure, using a transfer device having a cannula whose passageway is adapted to pass a suction member stem and an outer shroud adapted to fit over the receptacle closure comprisng the steps of: fitting the shroud over the closure, piercing the closure with the cannula while being guided by the shroud to permit access to the interior of the receptacle, inserting one of the suction members into the receptacle through the cannula, withdrawing fluid from the receptacle into the one suction member, removing the one suction member from the receptacle, and filling a second suction member from the receptacle through the cannula.
Claim 17
Dependent Claim
16 words
A device of claim 1 wherein the cannula has a penetrable, reclosable member closing the passageway.
Claim 18
Dependent Claim
14 words
A device of claim 15 wherein the penetrable member is a hydrophillic polyurethane foam.
Claim 19
Dependent Claim
26 words
A device of claim 15 wherein the cannula has an upper rim defining a caplike receptacle and which includes an annular retainer securing said penetrable member.
