The present disclosure relates generally to medical vial assemblies, and more particularly, to medical vials pre-attached with a vial adapter assembly for the transfer of gases/liquids/fluid or other substances to/from medical vials.
In one instance, hazardous medicines are frequently applied in the treatment of certain diseases, in particular, for example, in the treatment of cancer. Cytotoxic drugs have generally been used to kill cancer cells. However, the use of cytotoxic drugs, in the treatment of cancer cells, presents specific dangers to all cells, both in the patient and in healthcare providers. Although the exposure to a health care provider is normally very small for each cytotoxic drug dose administration, evidence suggests that chronic, low-dose exposure can produce significant health problems. Accordingly, a system that allows the safe handling of hazardous drugs while significantly reducing and/or eliminating the exposure to providers would be of great benefit.
Drugs are typically supplied in glass or plastic vials that are capped with a gas impermeable liquid seal or stopper. In some instances, the vial contents are a solid powder, such that a liquid needs to be injected for mixing (e.g., reconstitution). The injection of additional contents (e.g., liquid) into the vial produces an increased pressure which stresses the seal or stopper. Although the vial is intended to be sealed to liquid and gases, drug molecules in vapor phase can leak or pass around the sides of the stopper or through the stopper as the injection needle is withdrawn, thus presenting a hazard to the provider or clinician.
Accordingly, with the potential for aerosol leakage, leakage/spraying upon needle withdrawal, or spills, a means with which to prevent the accidental vapor phase drug egress is required.
Thus, a need exists for new components and systems capable of more efficiently transferring gases/fluids/liquids or other substances to/from a vial without leaking or spilling and without exposure of the liquids to substances outside the closed system. As such, healthcare personnel may more safely use and handle fluid substances including potentially hazardous liquids and the like.

Proximal gasket 415a may function as a retainer for retaining vial adapter assembly 400 connected to the neck of medical vial “V” while in the first position. Alternatively, annular stem 413 may include at least two pair of proximal-most retainers extending radially inwardly therefrom. The proximal-most retainers may be configured to connect vial adapter assembly 400 to the neck of medical vial “V” to form a connection, in the first position, between vial adapter assembly 400 and medical vial “V” when the neck of medical vial “V” is inserted into the central opening of annular stem 413.
Annular stem 413 also includes at least two pair of distal-most retainers 413b extending radially inwardly therefrom. Distal-most retainers 413b are disposed distal of proximal gasket 415a and distal gasket 415b. Distal-most retainers 413b of annular stem 413 are configured to connect vial adapter assembly 400 to the neck of medical vial “V” to form a connection, in the second position, between vial adapter assembly 400 and medical vial “V” when vial adapter assembly 400 is actuated from the first position to the second position. Each distal-most retainer 413b includes a shoulder or ledge 413c configured to engage the neck of the medical vial “V”.
A spike 405 of adapter assembly 400 extends away from proximal end 411 of vial adapter 410 and includes a tip configured to pierce the stopper or septum “S” provided on medical vial “V”.
As described above, a medical vial “V” is provided with vial adapter assembly 400 pre-connected, pre-loaded or pre-attached thereto with vial adapter assembly 400 in the first position, wherein spike 405 of vial adapter assembly 400 does not penetrate stopper “S” of medical vial “V”. When vial adapter assembly 400 is in the first position, the neck of the medical vial “V” extends through central opening 415c of gasket 415 wherein proximal gasket 415a forms a seal about the neck of the medical vial “V” and functions to help secure vial adapter assembly 400 to medical vial “V”.
In use, vial adapter 410 of vial adapter assembly 400 is actuated from the first position to the second position by proximally displacing vial adapter 410 relative to the neck of medical vial “V”. In so doing, spike 405 of vial adapter 410 is advanced to penetrate stopper “S” of medical vial “V”. When vial adapter assembly 400 is in the second position, distal gasket 415b may function to form a seal about the neck of the medical vial “V”.
For a more detailed discussion of the construction and operation of certain aspects, component and features of vial adapters 110, 210, 310 and 410, reference may be made to U.S. Pat. No. 9,107,809, the entire content of which is incorporated herein by reference.
It will be understood that various modifications may be made to the embodiments disclosed herein.
