Abstract

A vial adapter element for use in a drug mixing system including a body, a vial connection port extending from the body, a hollow vial puncturing spike that protrudes into the vial connection port and is in fluid communication with a syringe-adapter-element connection port that extends from the body, and a plurality of resilient tongues spaced around an inner wall of the body, the tongues being located in gaps formed in the inner wall of the body.

Claims

1. A vial adapter element for use in a drug mixing system comprising:

a body;

a vial connection port extending from said body;

a hollow vial puncturing spike that protrudes into said vial connection port and is in fluid communication with a syringe-adapter-element connection port that extends from said body; and

a plurality of resilient tongues spaced around an inner wall of said body, said tongues being located in gaps formed in the inner wall of said body.

2. The vial adapter element according to claim 1, further comprising a biasing device arranged to create a biasing force towards said resilient tongues.

3. The vial adapter element according to claim 1, wherein said body comprises an outwardly extending proximal rim.

4. The vial adapter element according to claim 1, wherein each tongue comprises a cantilevered arm that terminates in a chamfered lug, and said cantilevered arms extend along the inner wall of said body.

5. The vial adapter element according to claim 1, wherein each tongue comprises a cantilevered arm that terminates in a chamfered lug, said cantilevered arms being as thick as the inner wall of body, and wherein said chamfered lugs are thicker than said cantilevered arms.

6. The vial adapter element according to claim 1, wherein each tongue comprises a cantilevered arm that terminates in a chamfered lug, and each chamfered lug extends radially towards a center of said body and is located at a proximal end of a cutout formed in said body.

7. The vial adapter element according to claim 2, wherein said biasing device comprises a coil spring.

8. The vial adapter element according to claim 2, wherein said biasing device comprises a flexible cylindrical element having a hole for said spike to pass therethrough.

9. The vial adapter element according to claim 3, wherein said body comprises a conical flange that extends inwards from said rim.

10. The vial adapter element according to claim 9, wherein each tongue comprises a cantilevered arm that terminates in a chamfered lug, and each cantilevered arm depends from a proximal end of a cutout formed in said conical flange, and an appendage extends from a distal edge of said cantilevered arm from which extends said chamfered lug.

11. The vial adapter element according to claim 1, wherein each tongue comprises a cantilevered arm that terminates in a chamfered lug, and each cantilevered arm extends from a floor of said body and is located in a cutout formed in said body, and an appendage extends from a distal edge of said cantilevered arm from which extends said chamfered lug.

12. The vial adapter element according to claim 2, wherein said hollow vial puncturing spike is mounted in a counterbore formed in said body and said biasing device is placed in said counterbore.
