Abstract

Liquid transfer devices with an integral telescopic vial adapter for use with an infusion liquid container and an initially non-punctured intact discrete injection vial. The integral telescopic vial adapter is configured for initial telescopic snap mounting on a discrete injection vial leaving its injection vial stopper non-punctured until a subsequent compaction for puncturing the injection vial stopper. The integral telescopic vial adapter includes a safety catch mechanism for precluding advertent compaction from a pre-compacted state to a compacted state. The integral telescopic vial adapter includes a clamping arrangement for irreversibly clamping same in its final compacted state.

First claim

The invention claimed is:

1. A liquid transfer device for use with an infusion liquid container containing an infusion liquid and having an intravenous (IV) port for administering the infusion liquid, a discrete injection vial having a closed end vial tube containing a medicament, a tubular vial crown with a crown opening stopped by a non-punctured injection vial stopper, and an uppermost injection vial surface, and an infusion set including an infusion set IV spike for sealing insertion into a substitute IV port and a connector for administration purposes to a patient,
the liquid transfer device comprising a trifurcated connector body having a liquid transfer device IV spike for sealing insertion into the infusion liquid container's IV port, a vial adapter port with an integral telescopic vial adapter for telescopic snap fit mounting on the discrete injection vial, and the substitute IV port for sealingly receiving the infusion set IV spike,
said liquid transfer device IV spike, said vial adapter port and said substitute IV port being in 3 way direct and continuous fluid communication thereby enabling an initial forming of a medicated infusion liquid in the infusion liquid container and a subsequent administration of the mediated infusion liquid to a patient,
said integral telescopic vial adapter having a longitudinal vial adapter centerline and comprising:
an inner vial adapter body having an inverted cup shape with an uppermost transverse annular inner vial adapter body wall and a downward depending vial crown sleeve with a lowermost vial crown sleeve rim,
said inner vial adapter body bounding a vial crown cavity for snugly receiving the tubular vial crown on telescopic mounting said inner vial adapter body thereon,
an outer vial adapter body having an inverted cup shape with an uppermost transverse outer vial adapter body wall and a downward depending skirt,
said outer vial adapter body bounding an inner vial adapter body cavity for snugly telescopically receiving said inner vial adapter body therein on compacting said integral telescopic vial adapter from an initial pre-compacted state having a pre-compacted height H 1 to a final compacted state having a compacted height H 2 where H 1 >H 2 , wherein said pre-compacted height H 1 and said compacted height H 2 are between said uppermost transverse outer vial adapter body wall and said lowermost vial crown sleeve rim,
a downward puncturing cannula with a proximal puncturing cannula opening in flow communication with said vial adapter port and a distal puncturing cannula tip for puncturing the injection vial stopper for flow communication with the vial tube,
a safety catch mechanism for preventing inadvertent user compaction of said vial adapter from said pre-compacted state to said compacted state, and
a clamping arrangement for irreversibly clamping said vial adapter in said final compacted state,
said vial adapter being configured such that in said pre-compacted state, said distal puncturing cannula tip overlies the non-punctured injection vial stopper and, in compacted state, said distal puncturing cannula tip punctures through the injection vial stopper for flow communication with the vial tube.

2. The device according to claim 1 wherein said safety catch mechanism is constituted by a twist release safety catch mechanism including:
a diametric pair of L-shaped tracks in said outer vial adapter body,
each said L-shaped track having a major track leg co-directional with said longitudinal vial adapter centerline, a minor track leg transverse to said longitudinal vial adapter centerline, a start track end adjacent said lowermost downward depending skirt rim and a finish track end adjacent said uppermost transverse outer vial adapter body wall,
each said minor track leg including a one-way passage arrangement for irreversibly priming said integral telescopic vial adapter in an intermediate primed state,
a diametric pair of radial outward projections on said inner vial adapter body for travelling along said diametric pair of L-shaped tracks from said start track end in said pre-compacted state to said finish track end in said compacted state,
said twist release safety catch mechanism requiring an initial manual rotation of said inner vial adapter body with respect to said outer vial adapter body about said longitudinal vial adapter centerline for priming said vial adapter from an initial pre-compacted state to said intermediate primed state for enabling said compaction of said vial adapter from said pre-compacted state to said compacted state.

3. The device according to claim 2 wherein each said finish track end includes a one-way passage arrangement for irreversibly clamping said vial adapter in said final compacted state.

4. The device according to claim 2 wherein said inner vial adapter body has a diametric pair of radial outward finger grips towards said lowermost downward depending vial crown sleeve rim and said outer vial adapter body has a diametric pair of anti-slip surfaces orthogonal to said diametric pair of radial outward finger grips in said initial pre-compacted state for assisting said manual rotation of said inner vial adapter body with respect to said outer vial adapter body.

5. The device according to claim 1 wherein said safety catch mechanism is constituted by a pull release safety catch mechanism requiring an initial manual extension of said inner vial adapter body with respect to said outer vial adapter body co-directional with said longitudinal vial adapter centerline to an intermediate primed state to release said safety catch mechanism for enabling said compaction of said vial adapter from said pre-compacted state to said compacted state.

6. The device according to claim 1 wherein said safety catch mechanism includes a safety catch transversely extending through said outer vial adapter body in said pre-compacted state thereby blocking said compaction of said integral telescopic vial adapter from said pre-compacted state to said compacted state whereby a manual withdrawal of said safety catch from said outer vial adapter body enables said compaction of said integral telescopic vial adapter from said pre-compacted state to said compacted state.

7. The device according to claim 1 for use with an intact discrete injection vial release tool with an opposite pair of inward directed protrusions for applying a pincers-like compression for releasing a non-punctured intact discrete injection vial from said integral telescopic vial adapter,
said vial crown sleeve including a major vial crown sleeve surround and a diametric pair of injection vial holding members pivotal with respect thereto such that each said vial crown holding member has a proximal vial crown holding member section and a distal vial crown holding member section,
each said distal vial crown holding member section having a radial inward vial crown holding projection towards said lowermost vial crown sleeve rim for snap fitting under the vial crown on telescopic snap fitting said inner vial adapter body on the initially non-punctured intact discrete injection vial,
said diametric pair of proximal vial crown holding member sections being pivotal with respect to said major vial crown sleeve surround such that application of the pincers-like compression on said diametric pair of proximal vial crown holding member sections distances said diametric pair of radial inward vial crown holding projections from said longitudinal vial adapter centerline for releasing the non-punctured intact discrete injection vial from said inner vial adapter body.

8. The device according to claim 7 wherein said downward depending skirt includes a diametric pair of through going discrete injection vial release apertures for providing acce
