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, comprising:

a holding unit for holding a reservoir, the holding unit configured such that a plunger arm that is connected to a plunger head that is within the reservoir is moveable when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media;

a vibrator for vibrating the holding unit so as to vibrate the reservoir; and

a transfer guard for transferring fluidic media from a vial to the reservoir when the holding, unit is holding the reservoir, the transfer guard including a first end for at least partially surround in a port of the reservoir when a needle of the transfer guard pierces a septum in the port of the reservoir.

2. The system of claim 1, the vibrator configured to vibrate the holding unit when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media, so as to vibrate the reservoir and cause air bubbles within the fluidic media to travel upwards within the reservoir.

3. The system of claim 1, the vibrator configured to shake the holding unit sufficiently when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media so as to shake air bubbles free in the fluidic media.

4. The system of claim 1, the holding unit comprising:

a first holder; and

a second holder;

the plunger arm moveable within a space between the first holder and the second holder when the reservoir is being held by the first holder and the second holder and the reservoir is being filled with fluidic media.

5. The system of claim 4, the first holder and the second holder connected to the vibrator.

6. The system of claim 4, wherein said space is also at least partially between the plunger arm and the vibrator.

7. The system of claim 1, the holding unit configured such that, when the holding unit is holding the reservoir, fluidic media is fillable into the reservoir through a port of the reservoir that is located to an opposite side of said plunger head from said plunger arm.

8. The system of claim 1, the holding unit configured such that the plunger arm is moveable in a direction toward the vibrator when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media.

9. The system of claim 1, the system further comprising:

one or more latches for preventing the plunger arm from being moved when the holding unit is holding the reservoir and prior to a time when the reservoir is being filled with fluidic media.

10. The system of claim 1, the holding unit configured such that a handle connected to the plunger arm is moveable within a space between the reservoir and the vibrator when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media.

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

providing a holding unit for holding a reservoir, the holding unit configured such that a plunger arm that is connected to a plunger head that is within the reservoir is moveable when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media;

locating a vibrator for vibrating the holding unit so as to vibrate the reservoir; and

providing a transfer guard for transferring fluidic media from a vial to the reservoir when the holding unit is holding the reservoir, at least partially surrounding a ort of the reservoir with a first end of the transfer guard, and piercing a septum in the port of the reservoir with a needle of the transfer guard.

12. The method of claim 11, further comprising vibrating the holding unit with the vibrator when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media, so as to vibrate the reservoir and cause air bubbles within the fluidic media to travel upwards within the reservoir.

13. The method of claim 11, further comprising shaking the holding unit with the vibrator sufficiently when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media so as to shake air bubbles free in the fluidic media.

14. The method of claim 11, comprising:

providing the holding unit with a first holder and a second holder; and

moving the plunger arm within a space between the first holder and the second holder when the reservoir is being held by the first holder and the second holder and the reservoir is being filled with fluidic media.

15. The method of claim 14, her comprising connecting the first holder and the second holder to the vibrator.

16. The method of claim 14, wherein said space is also at least partially between the plunger arm and the vibrator.

17. The method of claim 11, further comprising adding fluidic media into the reservoir through a port of the reservoir that is located to an opposite side of said plunger head from said plunger arm when the holding unit is holding the reservoir.

18. The method of claim 11, further comprising moving the plunger arm in a direction toward the vibrator when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media.

19. The method of claim 11, further comprising providing one or more latches that prevent the plunger arm from being moved when the holding unit is holding the reservoir and prior to a time when the reservoir is being filled with fluidic media.

20. The method of claim 11, moving a handle connected to the plunger arm within a space between the reservoir and the vibrator when the holding unit is holding the reservoir and the reservoir is being filled with fluidic media.
