Liquid drug medical device
The present invention relates to liquid drug medical devices for enabling the administration of liquid drugs, and also a needle shield removal device for safely removing needle shields.
1. A liquid drug medical device for use with a syringe having a syringe tip with a distal end with a laterally projecting lip having an external diameter D 2 , and a medicinal vial with a rubber stopper, the device comprising an adapter for snap fitting onto the vial and including a hollow puncturing member rigidly connected to said adapter for puncturing the rubber stopper on snap fitting said adapter on the vial,
characterized in that
the device further comprises a short elastomer tubing in flow communication with said puncturing member, and having a distal end with a nominal internal diameter D 1 <D 2 and of at least 3 mm configured to sealingly stretch over the syringe's laterally projecting lip for effecting fluid communication between the syringe and the medicinal vial.
2. The device according to claim 1 wherein said tubing has a length L=10-20 mm.
3. The device according to claim 2 wherein said vial adapter has an upright nipple and said tubing is mounted on said nipple.
4. The device according to claim 3 wherein said vial adapter is over molded on said tubing.
5. The device according to claim 3 wherein said liquid drug medical device is manufactured by two material injection molding.
6. The device according to claim 1 wherein the vial adapter has an upright nipple and the tubing is mounted on said nipple, and wherein a proximal end of the tubing contacts a top wall of the vial adapter.
7. The device according to claim 1 wherein a proximal end of the tubing extends at least partially into a top wall of the vial adapter.
