A needle assembly structured to facilitate substantially complete removal, if not the complete removal, of a pharmaceutical or other composition from a vial or like container. The needle assembly comprises a delivery needle having an elongated first portion of sufficient length to extend within and along the entire length of the interior of the vial. A distal end of the delivery needle is disposable in confronting engagement with an interior floor portion of the vial. The delivery needle is connected to a base and is concurrently movable relative thereto while maintaining the distal end of the first portion in confronting relation to the vial floor. Complete removal of the pharmaceutical composition from the vial is thereby facilitated.

What is claimed is: 1. A needle assembly structured to facilitate at least substantially complete removal of a composition from a container, said needle assembly comprising: a) a base movable exteriorly of the container, b) a delivery needle including a first portion and a second portion, and a first intermediate portion and a second intermediate portion disposed in interconnecting relation to said first and second portions, c) said first portion being of sufficient length to extend into and along substantially an entire interior length of the container, d) said second portion connected in substantially transverse relation to said first portion and movable therewith, said second portion disposed exteriorly of the container, e) a passage assembly formed in said base, said passage assembly disposed and structured to allow axial movement of said first portion and transverse movement of said second portion through corresponding portions of said passage assembly, f) a stop structure including a first stop member and a secondary stop member disposed within said passage assembly in spaced relation to one another, g) said first intermediate portion movable through and within said passage assembly into and out of movement restricting engagement with said first stop member, h) said second intermediate portion movable through and within said passage assembly into and out of movement restricting engagement with said secondary stop member, and i) a vent assembly including a vent needle fixedly secured to said base and movable therewith relative to the container, said vent needle including a distal tip disposed interiorly of the container and a proximal end disposed exteriorly of the container. 2. A needle assembly as recited in claim 1 further comprising said passage assembly formed on said base, said first portion movable in an axial direction through said passage assembly and second portions movable through said passage assembly in a transverse direction relative to said base. 3. A needle assembly as recited in claim 1 further comprising a filter structure disposed adjacent said proximal end of said vent needle and structured to filter gas passing through said vent needle. 4. A needle assembly as recited in claim 1 wherein said vent needle comprises a substantially angular configuration. 5. A needle assembly as recited in claim 1 wherein said first stop member is disposed to prevent axial movement of said first portion through said passage assembly in a first direction when said first portion is disposed into engagement with said first stop member. 6. A needle assembly as recited in claim 5 wherein said secondary stop member is disposed to prevent axial movement of said first portion in a second direction, opposite to said first direction, and concurrently prevent transverse movement of said second portion within and through said passage assembly in said second direction. 7. A needle assembly structured to facilitate complete removal of a liquid from a container, said needle assembly comprising: a) a base movably disposable exteriorly of the container and including a needle assembly connected thereto, b) said needle assembly comprising a delivery needle including a first portion having an open distal end disposable within the container in fluid communication with the liquid therein, c) said first portion having a sufficient length to extend into and along substantially an entire interior length of the container, d) said delivery needle including a second portion connected to said first portion in substantially transverse relation thereto and disposed exteriorly of the container, said delivery needle further including a first intermediate portion and a second intermediate portion disposed in interconnecting relation with said first and second portions, e) said base including a passage assembly comprising a first opening and a second opening disposed in spaced relation to one another and dimensioned to movably receive said first portion and said second portion therethrough, f) said first opening cooperatively disposed with said first portion to allow passage of said first portion therethrough in an axial direction, g) said second opening cooperatively disposed with said second portion to allow passage of said second portion therethrough in a transverse direction, h) said first and second portions integrally connected to one another and relatively disposed to pass through corresponding ones of said first and second openings, i) a stop structure including a first stop member and a secondary stop member disposed within said passage assembly in spaced relation to one another, j) said first intermediate portion of said delivery needle being movable through and within said passage assembly into and out of movement restricting engagement with said first stop member, k) said second intermediate portion of said delivery needle movable through and within said passage assembly into and out of movement restricting engagement with said secondary stop member, l) said base movable along an axis of said first portion to confronting engagement of a distal end of said first portion with a floor portion of the container, and m) a vent needle fixedly connected to said base and movable with said base relative to the container. 8. A needle assembly as recited in claim 7 further comprising said vent needle fixedly connected to said base in spaced relation to and independently of said delivery needle, said vent needle disposed to define a path of fluid flow between the interior and exterior of the container. 9. A needle assembly as recited in claim 8 further comprising a filter structure disposed adjacent an exterior end of said vent needle and structured to filter fluid passing through said vent needle.
