Abstract

In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a housing and a bag. In some embodiments, an initial volume of a regulating fluid can be contained within the bag. In some embodiments, the regulating fluid flows into the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In some embodiments, a vial adaptor is coupled with the vial in order to remove the liquid. In some embodiments, as the liquid is removed from the vial via the adaptor, the bag expands, and in other embodiments, the bag contracts.

Claims

1. An adaptor configured to couple with a sealed vial containing a volume of a medical fluid, the adaptor comprising:

a housing member including a distal extractor aperture configured to permit withdrawal of the medical fluid from the sealed vial when the adaptor is coupled to the sealed vial, wherein at least a portion of an extractor channel and at least a portion of a regulator channel pass through the housing member; and

a reservoir in fluid communication with the regulator channel, the reservoir containing an initial volume of a regulating fluid that is equal to or greater than the volume of medical fluid contained in the vial, the reservoir configured to contract when the medical fluid is withdrawn from the sealed vial via the extractor channel,

wherein the reservoir is configured to supply at least some of the initial volume of regulating fluid to the vial via the regulator channel prior to any fluid being introduced into the sealed vial via the extractor channel, thereby facilitating immediate withdrawal of the medical fluid from the sealed vial and compensating for such withdrawal of the medical fluid from the vial.

2. The adaptor of claim 1, wherein further comprising a medical connector interface in fluid communication with the extractor channel.

3. The adaptor of claim 2, wherein the medical connector interface is configured to interface with a needle-less connector.

4. The adaptor of claim 1, wherein the reservoir is outside of the vial.

5. The adaptor of claim 1, wherein the reservoir is within the housing member.

6. The adaptor of claim 1, wherein the reservoir comprises a balloon.

7. The adaptor of claim 1, wherein the housing member comprises a plurality of components attached in substantially airtight engagement.

8. The adaptor of claim 1, wherein the initial volume of regulating fluid comprises sterilized air.

9. The adaptor of claim 1, further comprising a filter in communication with the regulator channel.

10. The adaptor of claim 9, wherein the filter is hydrophobic.

11. A method of manufacturing an adaptor configured to couple with a sealed vial containing a medical fluid, the method comprising:

forming a housing member, the housing member including a distal extractor aperture configured to permit withdrawal of the medical fluid from the sealed vial when the adaptor is coupled to the sealed vial, wherein at least a portion of an extractor channel and at least a portion of a regulator channel pass through the housing member; and

placing a reservoir in fluid communication with the regulator channel, the reservoir containing an initial volume of a regulating fluid that is equal to or greater than the volume of medical fluid contained in the vial, the reservoir configured to contract when the medical fluid is withdrawn from the sealed vial via the extractor channel,

wherein the reservoir is configured to supply at least some of the initial volume of regulating fluid to the vial via the regulator channel prior to any fluid being introduced into the sealed vial via the extractor channel, thereby facilitating immediate withdrawal of the medical fluid from the sealed vial and compensating for such withdrawal of the medical fluid from the vial.

12. The method of claim 11, further comprising inserting sterilized air into the reservoir, the sterilized air being the regulating fluid.
