Abstract

A transfer guard for use by an individual for transferring contents from a supply container into a receiver container includes a supply adapter, a receiver adapter, a support structure and a needle. The supply adapter connects the supply container to the transfer guard, and the receiver adapter connects the receiver container to the transfer guard. The support structure couples the supply adapter with the receiver adapter, and the needle passes through the supply adapter and the receiver adapter. The needle is attached to one of the adapters for support and provides a passage for the contents to transfer from the supply container into the receiver container. The needle also includes at least one pointed end that is substantially protected by the transfer guard from contact with the user.

Claims

1. A transfer guard for use by an individual for transferring contents from a supply container to a receiver container that accepts the contents, the transfer guard comprising:

a supply adapter that is adapted to be mated with the supply container;

a receiver adapter that is adapted to be mated with the receiver container;

a support structure coupled between the supply adapter and the receiver adapter to support the supply adapter and the receiver adapter;

a locking mechanism engagable to substantially limit the supply adapter and receiver adapter from moving relative to each other; and

a needle that passes through the supply adapter and the receiver adapter, wherein the needle is attached to one of the adapters for support, wherein the needle provides a passage for the contents to transfer from the supply container through both of the adapters into the receiver container, wherein the needle includes at least one point that is substantially protected by the adapters from contact with the individual, and wherein the at least one needle point is exposed to the air after the containers are mated with the adapters and before the transfer guard is compressed.

2. A transfer guard according to claim 1, wherein the support structure facilitates movement of the adapters from a first more distant position relative to each other second closer position relative to each other.

3. A transfer guard according to claim 2, wherein the transfer guard includes a locking mechanism that may be engaged to keep the adapters from moving from a first more distant position relative to each other to a second closer position relative to each other.

4. A transfer guard according to claim 1, wherein the support structure includes a foam member that is compressible to move the adapters in closer proximity to each other.

5. A transfer guard according to claim 1, wherein the support structure is comprised of at least two threaded parts that are screwed together to move one adapter in closer proximity to the other adapter.

6. A transfer guard according to claim 1, wherein the support structure is comprised of at least two parts, one of the at least two parts has at least one slot and another of the at least two parts has at least one pin that slides in the at least one slot to move one adapter in closer proximity to the other adapter.

7. A transfer guard according to claim 1, wherein the support structure is comprised of at least two parts that slide together to move one adapter in closer proximity to the other adapter.

8. A transfer guard according to claim 1, wherein the locking mechanism engages when the adapters are moved from a first more distant position relative to each other to a second closer position relative to each other.

9. A transfer guard according to claim 1, wherein the needle has two ends and wherein each end of the needle extends into a container when the containers are mated with the adapters and the adapters are moved from a first more distant position relative to each other to a second closer position relative to each other.

10. A transfer guard according to claim 1, wherein the transfer guard is free of a septum.

11. A transfer guard for use by an individual for transferring contents from a supply container to a receiver container that accepts the contents, the transfer guard comprising:

a supply adapter that is adapted to be mated with the supply container;

a receiver adapter that is adapted to be mated with the receiver container;

a support structure coupled between the supply adapter and the receiver adapter to support the supply adapter and the receiver adapter;

a locking mechanism engagable to substantially limit the supply adapter and receiver adapter from moving relative to each other; and

a fluid conducting element that provides fluid communication through the supply adapter and the receiver adapter, wherein the fluid conducting element provides a passage for the contents to transfer from the supply container into the receiver container, wherein the fluid conducting element includes at least one end that is substantially protected by the adapters from contact with the individual, and wherein the at least one end is exposed to the air after the containers are mated with the adapters and before the transfer guard is compressed.

12. A transfer guard according to claim 11, wherein the fluid transfer conduit is a needle and wherein the needle is attached to one of the adapters for support.

13. A transfer guard for use by an individual for transferring contents from a supply container through a fluid conducting element to a receiver container that accepts the contents, wherein the fluid conducting element is protected from contact with the individual, the transfer guard comprising:

a supply adapter that is adapted to be mated with the supply container;

a receiver adapter that is adapted to be mated with the receiver container;

a locking mechanism engagable to substantially limit the supply adapter and receiver adapter from moving relative to each other; and

a support structure coupled between the supply adapter and the receiver adapter to support the supply adapter and the receiver adapter,

wherein the support structure facilitates movement of the adapters from a first more distant position between the adapters to a second closer position between the adapters, and wherein the support structure includes hinges that fold to move one adapter in closer proximity to the other adapter.

14. A transfer guard according to claim 13, further including a locking mechanism that may be engaged to keep the adapters from moving apart from each other.

15. A transfer guard for use by an individual for transferring contents from a supply container to a receiver container that accepts the contents, the transfer guard comprising:

a supply adapter that is adapted to be mated with the supply container;

a receiver adapter that is adapted to be mated with the receiver container;

a support structure coupled between the supply adapter and the receiver adapter to support the supply adapter and the receiver adapter;

a locking mechanism engagable to substantially limit the supply adapter and receiver adapter from moving relative to each other; and

a needle that passes through the supply adapter and the receiver adapter, wherein the needle is attached to one of the adapters for support, wherein the needle provides a passage for the contents to transfer from the supply container through both of the adapters into the receiver container, wherein the needle includes at least one point that is substantially protected by the adapters from contact with the individual, and wherein the support structure includes hinges that fold to move the adapters in closer proximity to each other.

16. A transfer guard for use by an individual for transferring contents from a supply container to a receiver container that accepts the contents, the transfer guard comprising:

a supply adapter that is adapted to be mated with the supply container;

a receiver adapter that is adapted to be mated with the receiver container;

a support structure coupled between the supply adapter and the receiver adapter to support the supply adapter and the receiver adapter, wherein the support structure includes bands that bend to move one adapter in closer proximity to the other adapter; and

a needle that passes through the supply adapter and the receiver adapter, wherein the needle is attached to one of the adapters for support, wherein the needle provides a passage for the contents to transfer from the supply container through both of the adapters into the receiver container, and wherein the needle includes at least one point that is substantially protected by the adapters from contact with the individual.

17. A transfer guard for use by an individual for transferring contents from a supply container to a receiver container that accepts the contents, the transfer guard comprising:
