This application is a Section 371 of International Application No. PCT/IL2010/000777, filed Sep. 21, 2010, which was published in the English language on Apr. 7, 2011, under International Publication No. WO 2011/039747 A1, and the disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

This invention relates to vial assemblages including a vial with a pre-attached fluid transfer device for use with a needleless syringe.

BACKGROUND OF THE INVENTION

Liquid drug reconstitution for reconstitution of medicaments supplied in vials generally involves multiple steps including inter alia opening a vial adapter package for preparing a vial adapter with a cannula for use, preparing a sealed vial for use, co-axial alignment of the vial adapter with the vial and subsequent manually snap fitting the vial adapter onto the vial such that the vial adapter's cannula punctures the vial's stopper. Such vial adapters are commercially available from, for example, Medimop Medical Projects Ltd, Ra'anana, Israel. Such multiple steps take considerable preparation time and introduce a margin for error in the procedure. Moreover, many users inadvertently misalign the vial adapter with the vial such that the former's cannula is unable to puncture the vial's stopper for flow communication purposes. Furthermore, some users initially accurately align the vial adapter with the vial but then incline the vial adapter while manually snap fitting the same for puncturing the vial, thereby precluding flow communication.

Vial assemblages with a vial and a pre-attached fluid transfer device are illustrated and described in inter alia EP 1 008 337, EP 1 029 526, FR 2 029 242, GB 1 442 210, U.S. Pat.

SUMMARY OF THE INVENTION

The present invention is directed towards vial assemblages with a vial and a pre-attached fluid transfer device for use with a needleless syringe for enabling flow communication between the syringe and the vial. Vials are typically sealed by a stopper in a conventional manner. Stoppers have a pre-formed axial blind bore with a bore end leaving a reduced stopper thickness between the bore end and the vial interior. Fluid transfer devices have an elongated tubular flow member including a connector and a spike for initial intimate sealing non-puncturing pre-insertion into the blind bore. Connectors are sealed by a closure for maintaining sterile conditions. Spike tips are in proximity to or possibly contacting a bore end for facilitating stopper puncturing for establishing flow communication with vial interiors. Connectors preferably have an external screw thread and closures are preferably constituted by a screw cap screw threaded thereon. Connectors can be either female or male for suitable sealing flow communication with a syringe with a mating connector. Connectors are preferably Luer connectors. Other suitable closures include inter alia a tear off seal, and the like.

Fluid transfers device are manually urged from an initial non-communication set-up position to a flow communication position. Fluid transfer devices preferably include a flow member arrest arrangement for stopping displacement of a flow member towards a vial on manual urging to its flow communication position such that its spike end protrudes a predetermined distance into a vial interior for flow communication purposes. Fluid transfer devices also preferably include a flow member securing arrangement for preventing manual removal of a closure inadvertently withdrawing a flow member from its blind bore. In the case of a screw cap, flow member securing arrangements prevent rotation of the flow member relative to the stopper during unscrewing of the screw cap and screwing a syringe onto the connector.

Fluid transfer devices may also include a safety catch mechanism requiring priming for subsequent manual depression of a fluid transfer device from a non-flow communication set-up position to a flow communication position for precluding inadvertent stopper puncturing. Safety catch mechanisms preferably lock a flow member so that its movement is substantially prevented towards or away from a vial until released. Safety catch mechanisms may also include a tamper-proof arrangement which prevents a user returning a safety catch mechanism to its initial position once a user has primed same ready for manually urging its flow member from an initial non-flow communication set-up position to a subsequent flow communication position.

Vial assemblages of the present invention afford convenient and sterile liquid drug reconstitution precluding the initial preparation steps of a vial and a vial adapter and the subsequent assembly steps of aligning a vial adapter with a vial before snap fitting the former on the latter. Moreover, by virtue of the stoppers having a considerably reduced thickness at their bore ends compared to conventional stoppers, the pre-inserted spikes are ensured to puncture through the stoppers to achieve flow communication with the vial interiors. Furthermore, the blind bores act to guide their pre-inserted spikes during aforesaid manual depression thereby reducing the likelihood of inadvertent inclination of a fluid transfer device with respect to a vial.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

FIGS. 1 to 5 show a vial assemblage 100A having a two part construction including a vial 101 and a pre-attached fluid transfer device 102. The vial 101 has a longitudinal axis 101A and includes a vial body 103 having a vial interior 104 for storing a powdered or liquid medicament 106, a vial rim 107 defining a vial opening, and an intermediate narrow diameter vial neck 108 between the vial interior 104 and the vial rim 107. The vial 101 is sealed by a stopper 109 having an exposed uppermost stopper surface 109A. The vial 101 is hermetically sealed by a band 111. The stopper 109 is formed with a blind bore 112 with a bore end 112A of reduced stopper thickness between the bore end 112A and the vial interior 104.

The fluid transfer device 102 has a longitudinal axis 102A substantially co-axial with the longitudinal axis 101A and includes an elongated tubular flow member 113. The flow member 113 includes a connector 114, a spike 116, and a single lumen 117 extending lengthwise between the connector 114 and the spike 116 for flow communication therebetween. The spike 116 is in intimate sealing contact with the stopper 109 and has a spike end 116A proximate the bore end 112A not puncturing the stopper 109 in an initial non-flow communication set-up position (see FIGS. 1 and 2) and puncturing through the bore end 112A in a flow communication position (see FIGS. 4 and 5). The connector 114 has an external screw thread 118 sealed by a closure 119 constituted by a screw cap for keeping the connector 114 sterile. The connector 114 shown in the drawings is a female Luer connector.

The fluid transfer device 102 includes a flow member arrest arrangement 120 for stopping displacement of the flow member 113 toward the vial 101 such that the spike end 116A punctures through the stopper 109 to a predetermined distance for flow communication purposes on manual urging of the flow member 113 from its non-flow communication set-up position (see FIGS. 1 and 2) to its flow communication position (see FIGS. 4 and 5). The flow member arrest arrangement 120 is constituted by an annular flange 121 intermediate the connector 114 and the spike 116 disposed above the uppermost stopper surface 109A in the non-flow communication set-up position and bearing thereagainst in the flow communication position.

The fluid transfer device 102 includes a flow member securing arrangement 130 for displacement of the flow member 113 from the stopper 109 on manual removal of the closure 119 from the connector 114. The flow member securing arrangement 130 prevents rotation of the flow member 113 relative to the stopper 109 during unscrewing of the screw cap 119 and subsequent screwing a syringe 140 onto the connector 114. The flow member securing arrangement 130 is constituted by a pair of opposite radial barbs 131 disposed above the stopper surface 109A in the vial assemblage 100A's set-up position (see FIGS. 1 and 2) and inserted into the stopper 109 in the vial assemblage 100A's flow communication position (see FIGS. 4 and 5).

FIGS. 6 to 8 show the use of the vial assemblage 100A with a syringe 140 having a male Luer lock connector 141 and containing a diluent 142 for reconstituting the vial's powder medicament 106 as follows:

FIG. 6 shows the vial assemblage 100A in its set-up position in which the spike 116 does not puncture the stopper 109 and the screw cap 119 seals the connector 114.

FIG. 7 shows the vial assemblage 100A in its flow communication position after depression of the flow member 113 towards the vial 101 as depicted by arrow A until it is stopped by the flange 121 bearing against the stopper surface 109A and the spike end 116A has punctured the stopper 109.

FIG. 8 shows the vial assemblage 100A after unscrewing the screw cap 119 in a counterclockwise direction B to expose the connector 114. The barbs 131 prevent rotation of the flow member 113 while unscrewing the screw cap 119 and also withdrawal of the flow member 113 from the stopper 109.

The syringe 140 is screwed in a clockwise direction C onto the connector 114 for enabling flow communication between the syringe 140 and the vial interior 104. The barbs 131 prevent rotation of the flow member 113 while screwing the syringe 140 onto the connector 114.

FIGS. 9 to 11 show a vial assemblage 100B similar to the vial assemblage 100A and therefore similar parts are likewise numbered. The vial assemblage 100B differs from the vial assemblage 100A insofar the former includes a fluid transfer device 102 with a pull ring type safety catch mechanism 150 for preventing inadvertent displacement of the flow member 113 from its set-up position towards its flow communication position leading to an inadvertent puncturing of the stopper 109.

The safety catch mechanism 150 includes a safety catch 151 having an upper near annular split flange grip 152 for gripping the flange 122, a lower near annular neck grip 153 for gripping the vial neck 108, and an upright rod 154 extending between the flange grip 152 and the neck grip 153. The safety catch mechanism 150 also includes a safety pull ring 156 for removing the safety catch 151 thereby allowing the flow member 113 to be manually depressed towards the vial 101. The safety pull ring 156 has an initial downward position co-directional with the vial's longitudinal axis 101A and is manually urged upwards into a subsequent transverse position relative to the vial's longitudinal axis 101A for enabling removal of the safety catch 151.

The safety catch mechanism 150 includes a tamper-proof arrangement 160 for preventing a user returning the safety catch mechanism 150 to its initial position once a user has primed same ready for manually urging the flow member 113 from its initial set-up position to its subsequent flow communication position. The tamper-proof arrangement 160 is constituted by the upright rod 154 being formed with a detent 161 for precluding the safety ring 156 to return from its subsequent transverse position to its initial downward position, thereby ensuring that the vial assemblage 100B is tamper proof.

The use of the vial assemblage 100B is similar to the vial assemblage 100A except in this case the safety catch mechanism 150 has to be initially primed and then removed before operation as per the steps shown in FIGS. 6 to 8. FIG. 12 shows initial priming of the vial assemblage 100B by manually urging the safety ring 156 upward from its initial downward position as depicted by arrow D to its transverse position shown in solid lines in FIG. 13. FIG. 13 shows final priming of the vial assemblage 100B ready for use following sideways removal of the safety catch mechanism 150 as depicted by arrow E.

FIGS. 14 to 16 show a vial assemblage 100C including a vial 101 and a fluid transfer device 201 having a longitudinal axis 201A substantially coaxial with the vial's longitudinal axis 101A. The fluid transfer device 201 includes an elongated tubular flow member 113 with a connector 114 with an external screw thread 118, a spike 116 with a spike end 116A, a lumen 117 and a screw cap 119. The fluid transfer device 201 includes a flow member arrest arrangement 120 for stopping displacement of the flow member 113 toward the vial 101 on manual urging of the flow member 113 from its non-flow communication set-up position to its flow communication position. The fluid transfer device 201 includes a flow member securing arrangement 130 for preventing upward displacement of the flow member 113 on manual removal of the closure 119 from the connector 114.

The fluid transfer device 201 includes a twist and depress safety catch mechanism 202 for preventing inadvertent downward displacement of the flow member 113 from an initial non-flow communication set-up position to a subsequent flow communication position for urging the spike end 116A through the stopper 109 into the vial interior 104. The safety catch mechanism 202 includes a cap-like member 203 integrally formed on the flow member 113 and telescopically mounted on a vial gripping member 204 having downward depending spaced apart flex members 206 for telescopically snap fitting onto the vial rim 107. FIG. 16 show the cap-like member 203 with a cut-away 203A to show the spike 116 which would otherwise be obscured from view. The fluid transfer device 201 further includes a tamper-proof arrangement 160 for preventing a user returning the safety catch mechanism 202 to its initial position once a user has primed same ready for manually urging the flow member 113 from its initial set-up position to its subsequent flow communication position.

The cap-like member 203 includes a top wall 207, and a downward depending skirt 208 formed with a pair of diametrically opposite slots 209 each having a generally U-shaped configuration disposed sideways with its open end facing in a counterclockwise direction. FIGS. 14, 16 and 17 show the front slot 209 only. The U-shaped slots 209 each include a substantially horizontal lowermost section 209A, a substantially horizontal uppermost section 209B and an upwardly inclined section 209C extending between the sections 209A and 209B. The skirt 208 is formed with a pair of latch members 211 at the junctions between the uppermost sections 209B and the inclined sections 209C for acting as part of the flow member securing arrangement 130 and the tamper-proof arrangement 160.

The vial gripping member 204 includes opposite side walls 212A and 212B and opposite upright resiliently flexible safety catches 213A and 213B interposed between the opposite side walls 212A and 212B. The safety catches 213 each have a radial outward pin 214 for traveling along their corresponding U-shaped slots 209. The safety catches 213 are intentionally capable of being flexed clockwise and counterclockwise relative to their unflexed upright positions. The pins 214 remain latched in the uppermost sections 209B by virtue of the latch members 211 thereby facilitating the counterclockwise unscrewing of the screw cap 119 as the pins 214 bear against the latch members 211. The pins 214 remain latched in the uppermost sections 209B on clockwise screwing of a syringe 140 onto the connector 114 as the pins 214 bear against the free ends of the uppermost sections 209B.

The safety catch mechanism 202, the flow member arrest arrangement 120, the flow member securing arrangement 130 and the tamper-proof arrangement 160 are operative with a single slot 209 and a safety catch 213. Provision of dual safety catches 213 ensures a more robust arrangement.

FIGS. 19 to 23 show the use of the vial assemblage 100C as follows:

FIG. 19 shows the vial assemblage 100C in its set-up position in which the cap-like member 203 is raised with respect to the vial gripping member 204, the safety catches 213 are in their upright positions and their pins 214 are located at the free ends of their lower sections 209As, the spike end 116A is pre-inserted in the stopper 109 proximate the bore end 112A, and the screw cap 119 seals the connector 114.

FIG. 20 shows priming of the vial assemblage 100C ready for use by manually rotating the cap-like member 203 in a clockwise direction depicted by arrow F relative to the vial gripping member 204 whereby the pins 214 are located at the junctures between the lower sections 209A and the upright sections 209C.

FIG. 21 shows the vial assemblage 100C in its flow communication position subsequent to depression of the cap-like Member 203 towards the vial gripping member 204 as depicted by arrow G to puncture the stopper 109. The safety catches 213 are initially flexed in a counterclockwise direction as the pins 214 are forcibly urged along the upright section 209C on depression of the cap-like member 203. The safety catches 213 are able to revert to their unflexed positions by urging their pins 214 to snap past the latch members 211 thereby preventing a user to return the cap-like member 203 to its initial position (see FIG. 19).

FIG. 22 shows the counterclockwise unscrewing of the screw cap 119 as denoted by arrow H to expose the connector 114.

FIG. 23 shows the clockwise screwing of a needleless syringe 140 in a clockwise direction J onto the connector 114 for enabling flow communication between the syringe 140 and the vial interior 104.

While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications, and other applications of the invention can be made within the scope of the appended claims.
