This invention relates to vial assemblages including a vial with a pre-attached fluid transfer device for use with a needleless syringe.
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. No. 2,326,490, U.S. Pat. No. 6,090,093, U.S. Pat. No. 6,681,946, US 2002/121496, WO 94/03373, WO 96/00053, WO 98/32411, WO 98/37854, WO 01/28490, WO 01/32524 and WO 2007/015233.
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.
In order to understand the invention and to see how it can be carried out in practice, preferred embodiments will now be described, by way of non-limiting examples only, with reference to the accompanying drawings in which similar parts are likewise numbered, and in which:
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
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
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
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.
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
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.
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.
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.
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.
