Abstract

Various embodiments of the present invention are directed to transferring fluidic media from a vial to a reservoir. In various embodiments, fluidic media may be transferred from the vial to the reservoir by moving a housing portion to move a plunger head located in the reservoir to draw fluidic media from the vial to the reservoir. In other embodiments, fluidic media may be transferred from the vial to the reservoir while the reservoir is held by a holding unit and vibrated by a vibrator to remove air from the fluidic media. In some embodiments, fluidic media may be transferred from the vial to the reservoir by moving a handle operatively connected to a bias member for assisting with the transfer of fluidic media. In other embodiments, the transfer of fluidic media may be assisted by a bias member and a needle connecting atmosphere and the vial.

Claims

1. A system for transferring fluidic media, the system comprising:

a housing portion for receiving a reservoir connected to a vial through a transfer guard;

a bias member held by the housing portion and arranged to provide a bias force directed to change a relative position of a plunger head within an interior volume of the reservoir, when the reservoir is received by the housing portion;

wherein the housing portion and the bias member are configured to transfer fluidic media between the vial and the reservoir, through the transfer guard, when the transfer guard is connected to the reservoir and the vial, the reservoir is received by the housing portion, and the bias force of the bias member changes the relative position of the plunger head within the interior volume of the reservoir.

2. A system according to claim 1, further comprising the transfer guard, wherein the transfer guard is connected to and provides a fluid flow path between the reservoir and the vial.

3. The system according to claim 1, further comprising:

a latch for holding the bias member in a first state, and for selectively releasing the bias member to move to a second state under the bias force to change the relative position of the plunger head within an interior volume of the reservoir.

4. The system according to claim 1, wherein the bias member comprises a spring.

5. The system according to claim 1, further comprising a handle movably held by the housing portion and operatively engageable with the plunger head, the handle arranged to receive the bias force from the bias member for moving the handle to change the relative position of the plunger head within the interior volume of the reservoir.

6. The system according to claim 5, wherein the housing portion and the bias member are configured such that fluidic media is transferred from the vial to the reservoir in a case where the reservoir is received by the housing portion, the handle is operatively engaged with the plunger head, and the handle is moved to change the relative position of the plunger head within the interior volume of the reservoir.

7. The system according to claim 5, further comprising:

a latch for supporting the handle when the latch is in a first position, and for releasing the handle to allow the handle to move when the latch is moved to a second position;

the bias member biased toward an expanded position and held compressed by the handle in a case where the latch is in the first position and the latch is supporting the handle; and

the bias member pushes on the handle so as to move the handle in a case where the latch is moved to the second position to release the handle.

8. The system according to claim 5, further comprising:

a plunger arm having a first end and a second end, the first end of the plunger arm connectable to the plunger head, the second end of the plunger arm connectable to the handle.

9. The system according to claim 5, wherein the bias member comprises a spring.

10. The system according to claim 1, further comprising a second housing portion for supporting the transfer guard, wherein the bias member is arranged to provide the bias force in a direction to change a relative position of the second housing portion and the housing portion for receiving the reservoir.

11. The system according to claim 10, wherein the housing portion for receiving the reservoir is coupled to hold the plunger of the reservoir while the bias member changes the relative position of the second housing portion and the housing portion for receiving the reservoir.

12. The system according to claim 11, further comprising the transfer guard, wherein the transfer guard is connected to and provides a fluid flow path between the reservoir and the vial, and wherein the transfer guard is configured to connect to a body of the reservoir, to move the body of the reservoir relative to the plunger of the reservoir, when plunger of the reservoir is held by the housing portion for receiving the reservoir and the bias force changes the relative position of the second housing portion and the housing portion for receiving the reservoir.

13. A method for transferring fluidic media, the method comprising:

receiving a reservoir by a housing portion;

connecting a transfer guard to provide a fluid path from a vial to the reservoir;

arranging a bias member in the housing portion to provide a bias force directed to change a relative position of a plunger head within an interior volume of the reservoir, when the reservoir is received by the housing portion;

changing the relative position of the plunger head within the interior volume of the reservoir by the bias force of the bias member to transfer fluidic media between the vial and the reservoir, when the transfer guard is connected to the reservoir and the vial, and the reservoir is received by the housing portion.

14. The method according to claim 13, further comprising:

holding the bias member in a first state with a latch, and selectively releasing the bias member with the latch, to move the bias member to a second state under the bias force to change the relative position of the plunger head within an interior volume of the reservoir.

15. The method according to claim 13, further comprising:

holding a moveable handle with the housing portion;

operatively engaging the handle with the plunger head;

arranging the handle to receive the bias force from the bias member for moving the handle to change the relative position of the plunger head within the interior volume of the reservoir.

16. The method according to claim 15, further comprising moving the handle under the bias force of the bias member to change the relative position of the plunger head within the interior volume of the reservoir.

17. The method according to claim 15, further comprising:

supporting the handle against the bias force of the bias member with the latch is in a first position;

moving the latch to a second position to release the handle to allow the handle to move under the bias force of the bias member, to change the relative position of the plunger head within an interior volume of the reservoir.

18. The method according to claim 15, wherein the bias member comprises a spring, the method further comprising:

providing a latch having a first state and a second state;

holding the spring in a compressed state by the handle in a case where the latch is in the first state; and

releasing the spring from the compressed state to move the handle in a case where the latch is in the second state.

19. The method according to claim 13, further comprising supporting the transfer guard with a second housing portion, wherein the bias member is arranged to provide the bias force in a direction to change a relative position of the second housing portion and the housing portion receiving the reservoir.

20. The method according to claim 19, further comprising coupling the plunger of the reservoir to the housing portion receiving the reservoir;

and operating the bias member to change the relative position of the second housing portion and the housing portion receiving the reservoir.
