Pressure-regulating vial adaptors
First Claim
1. An adaptor configured to couple with a sealed vial, the adaptor comprising:
- a connector interface;
an access channel in fluid communication with the connector interface;
a regulator assembly comprising;
a first regulator inlet in fluid communication with an ambient environment surrounding the adaptor;
a first regulator lumen;
a second regulator inlet in fluid communication with the ambient environment;
a second regulator lumen;
a first filter capable of fluid communication with the first regulator lumen and configured to filter fluid passing into the first regulator lumen;
a second filter in fluid communication with the second regulator lumen and configured to filter fluid passing from the second regulator lumen and into the ambient environment; and
a regulator valve in fluid communication with the first regulator lumen, the regulator valve configured to permit passage of fluid from the ambient environment into the first regulator lumen, the regulator valve further configured to prevent passage of fluid from within the vial to the first filter, the regulator valve comprising a valve stem and a flap portion;
a piercing member comprising a proximal end and a distal end, the distal end comprising a piercing tip; and
a regulator channel positioned at least partially within the piercing member and comprising a first regulator channel opening in fluid communication with the first regulator lumen,wherein the regulator assembly is configured to permit passage of fluid from the second regulator lumen to exit the adaptor and into the ambient environment.

Abstract
According to some embodiments of the present disclosure, an adaptor configured to couple with a sealed vial can include a connector interface. The adaptor can include one or more access channels (e.g., passages). In some cases the one or more access channels are in fluid communication with the connector interface. The adaptor can include a piercing member. The piercing member can include a regulator channel. The adaptor can include a regulator assembly. The regulator assembly can include a first regulator inlet. In some cases, the regulator includes a second regulator inlet. One or more of the first and second regulator inlets can include a filter configured to filter fluid passing into and/or out of the respective regulator inlets. One or more valves can be positioned between the first and/or second regulator inlets and the piercing member.
