Medicament vial assembly
The present disclosure relates to medical vials pre-attached with a vial adapter assembly for the transfer of gases/liquids/fluid or other substances to/from medical vials.
1. A vial adapter assembly for a closed fluid transfer system, the vial adapter assembly comprising:
a vial adapter, including:
a base defining an inner annular rim and an outer annular rim and a cavity therebetween;
an annular stem extending from the base and defining an opening having a plurality of fingers extending around the opening thereof, wherein each finger defines a proximal recess and a distal recess formed therein;
a cover supported on the outer annular rim, wherein an expansion chamber is defined within the cover and the base;
an adapter support situated within the cavity of the base, the adapter support including:
a male stem extending in a first direction from the base, the male stem selectively connectable to and insertable into an open distal end of a syringe adapter, the male stem defining a lumen extending therethrough;
a seal extending across the lumen of the male stem; and
a spike extending in a second direction from the inner annular rim and into the opening of the annular stem, wherein the spike includes a first lumen being in fluid communication with the lumen of the male stem, and wherein the spike includes a second lumen being in fluid communication with the expansion chamber; and
a bladder extending between the base and the cover; and
a vial collar including:
an annular body configured and dimensioned for sliding receipt within the annular stem of the vial adapter;
at least one tab projecting from an outer surface of the annular body and being configured for selective receipt in distal recess and proximal recess of a respective finger of the vial adapter; and
at least one retainer projecting from an inner surface of the annular body.
2. The vial adapter assembly according to claim 1 , wherein the vial adapter assembly includes a first position where the vial collar is extended relative to the annular stem, and a second position where the vial collar is retracted relative to the annular stem.
3. The vial adapter assembly according to claim 2 , wherein when the vial adapter assembly is in the first position, the at least one tab of the vial collar is disposed within the distal recess of a respective finger of the plurality of fingers of the annular stem.
4. The vial adapter assembly according to claim 3 , wherein when the vial adapter assembly is in the second position, the at least one tab of the vial collar is disposed within the proximal recess of a respective finger of the plurality of fingers of the annular stem.
5. The vial adapter assembly according to claim 4 , wherein the plurality of fingers of the annular stem of the vial adapter includes two pair of diametrically opposed fingers.
6. The vial adapter assembly according to claim 5 , wherein the at least one tab of the vial collar includes two pair of diametrically opposed tabs.
7. The vial adapter assembly according to claim 6 , wherein the at least one retainer of the vial adapter includes two pair of diametrically opposed retainers.
8. The vial adapter assembly according to claim 4 , wherein the plurality of fingers of the annular stem are resilient.
9. The vial adapter assembly according to claim 8 , wherein the spike of the vial adapter extends towards the annular body of the vial collar.
10. The vial adapter assembly according to claim 4 , wherein the spike of the vial adapter is configured to penetrate a stopper of a medical vial upon an actuation of the vial adapter assembly from the first position to the second position.
11. The vial adapter assembly according to claim 2 , wherein when the vial adapter assembly is in the second position, the at least one tab of the vial collar is disposed within the proximal recess of a respective finger of the plurality of fingers of the annular stem.
