Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
103 words
A transfer adaptor for fluid communication between a vial and a syringe, comprising a cannula having a proximal end for piercing a septum of the vial, the distal end of the cannula comprising a female receptor to receive the male exit nozzle of a syringe, a collar being provided between the proximal and distal ends of the cannula to prevent the adaptor passing entirely into the vial through the septum, characterised in that there is further provided, at the distal end of the cannula, a male receptor for the female opening of a reservoir whose contents are intended for transfer into the vial.
Claim 2
Dependent Claim
15 words
A transfer adaptor according to Claim 1, wherein the reservoir is a blow-fill seal ampoule.
Claim 3
Dependent Claim
28 words
A transfer adaptor according to Claim 1 or 2, wherein the male receptor of the transfer adaptor is so designed as to fit snugly into the female opening.
Claim 4
Dependent Claim
33 words
A transfer adaptor according to any preceding Claim, wherein the male receptor of the transfer adaptor is configured such that the contours of the male receptor exactly fit those of the female opening.
Claim 5
Dependent Claim
60 words
A transfer adaptor according to any of Claims 1 to 3, wherein the male receptor is elongated so that the base of the receptor is broader than it is expected to encounter with a female opening of an ampoule, while the tip of the receptor is narrower than it is expected to encounter with a female opening of an ampoule.
Claim 6
Dependent Claim
18 words
A transfer adaptor according to any preceding Claim, wherein the opening, receptors and nozzle are all essentially luer-shaped.
Claim 7
Dependent Claim
22 words
A transfer adaptor according to any preceding Claim, wherein the exit of the cannula bore is in the side of the cannula.
Claim 8
Dependent Claim
20 words
A transfer adaptor according to any preceding Claim, wherein the entire transfer adaptor is formed as an integral, injection-moulded unit.
Claim 9
Dependent Claim
25 words
A transfer adaptor according to any preceding Claim, wherein the female receptor of the transfer adaptor is contoured to fit exactly with the syringe nozzle.
Claim 10
Dependent Claim
19 words
A transfer adaptor according to any preceding Claim, wherein the collar is sufficiently wide to cover the entire septum.
Claim 11
Dependent Claim
36 words
A transfer adaptor according Claim 10, wherein the vial has a septum retaining collar and the collar of the adaptor is further provided with a dependent flange which extends down a wall of the septum-retaining collar.
Claim 12
Dependent Claim
33 words
A transfer adaptor according Claim 11, wherein at the extent of the flange there is provided an inwardly directed finger or catch which is adapted to snap over the septum-retaining collar in use.
Claim 13
Dependent Claim
18 words
A transfer adaptor according Claim 11 or 12, wherein the flange extends beyond the extent of the cannula.
Claim 14
Dependent Claim
25 words
A transfer adaptor according to any preceding claim, wherein an upwardly directed wall is provided about the male and female receptors of the transfer adaptor.
Claim 15
Dependent Claim
16 words
A transfer adaptor according to claim 14, wherein the upstanding wall is provided with a cover.
Claim 16
Dependent Claim
17 words
A transfer adaptor according to any preceding claim, wherein the adaptor forms a part of the ampoule.
Claim 17
Dependent Claim
54 words
A transfer adaptor for effecting fluid communication between a vial and another container, the adaptor comprising a connector for the container and a cannula for piercing a septum of the vial and for allowing passage of fluid between the vial and container, the cannula being provided with an opening in a side wall thereof.
Claim 18
Dependent Claim
21 words
An injection reconstitution system comprising a blow-fill-seal ampoule which contains liquid and a transfer adaptor as defined in any preceding Claim.
Claim 19
Independent Claim
56 words
A method of preparing an injectable composition, the method comprising transferring a reconstitution liquid from a blow-fill-seal ampoule to a vial containing an unreconstituted composition by means of a transfer adaptor as defined in any of Claims 1 to 17, and subsequently drawing reconstituted injectable composition into a syringe from the vial via the transfer adaptor.
