Pressure-regulating vial adaptors
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.

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.
2. The combination of the adaptor of claim 1 and the sealed vial.
3. The adaptor of claim 1 , wherein the flap portion of the regulator valve comprises a concave side and a convex side.
4. The adaptor of claim 1 , wherein the first regulator lumen and the second regulator lumen are in fluid communication with each other.
5. The adaptor of claim 1 , wherein the regulator valve is positioned in a plug portion that is inserted into the first regulator lumen.
6. The adaptor of claim 5 , wherein the plug portion is flexible.
7. The adaptor of claim 6 , wherein the plug portion is retained within the first regulator lumen by a friction fit.
8. The adaptor of claim 6 , wherein a cap portion limits the extent to which the plug portion is inserted into the regulator lumen.
9. The adaptor of claim 8 , wherein the first filter is positioned in the plug portion.
10. The adaptor of claim 1 , wherein the first filter is positioned within the first regulator lumen.
11. The adaptor of claim 10 , wherein the second filter is positioned within the second regulator lumen.
12. The adaptor of claim 1 , wherein the first and second filters are positioned along a common line that is generally perpendicular to the regulator channel.
13. The adaptor of claim 12 , wherein the regulator valve is positioned along the common line.
14. A method of manufacturing a vial adaptor comprising the steps of:
providing a connector interface;
providing an access channel in fluid communication with the connector interface;
providing a regulator assembly comprising:
