System for closed transfer of fluids

摘要

A system for the closed transfer of fluids that provides substantially leak-proof sealing and pressure equalization during engagement of a cannula with a vial, during transfer of a substance from a vial chamber to a barrel chamber via the cannula, and during disengagement of the cannula from the vial is disclosed. The leak-proof sealing of the system substantially prevents leakage of both air and liquid during use of the system. The system of the present disclosure also permits pressure equalization between a vial and the system when the system is attached to the vial. The system is compatible with a needle and syringe assembly for accessing a medication contained within a vial for administering the medication to a patient.

1. A system comprising:
a cannula having a proximal end and a distal end, the cannula attachable to a first container having a first chamber such that the cannula is in fluid communication with the first chamber; a syringe adapter having a housing and a cannula seal comprising a resilient sleeve, the cannula seal being disposed within the housing and moveable relative to the housing between a sealed position where the distal end of the cannula is enclosed by the cannula seal and a retracted position where the distal end of the cannula is positioned outside of the cannula seal, the housing including a first connection element; and a second container adapter attachable to a second container having a second chamber, the second container adapter having a second container seal and a second connection element, wherein with the first connection element of the syringe adapter engaged with the second connection element of the second container adapter, the syringe adapter is secured to the second container adapter, and wherein the cannula seal contacts the second container seal providing a substantially leak-proof seal during engagement of the cannula with the second container, during transfer of a first substance from the second chamber of the second container to the first chamber of the first container via the cannula, and during disengagement of the cannula from the second container.
