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 transfer guard providing a fluid path for transferring fluidic media from a vial to the reservoir when the holding unit is holding the reservoir; and

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

wherein the transfer guard and the reservoir are removable from the holding unit upon the reservoir being at least partially filled with the fluidic media;

wherein the transfer guard has a first end that selectively connects with the vial and a second end that selectively connects with the reservoir; and

wherein the holding unit has an interior in which at least a portion of the reservoir is received, when the holding unit is holding the reservoir and the second end of the transfer guard is connected with the reservoir, the reservoir being removable from the interior of the holding unit upon the reservoir being at least partially filled with the fluidic media.

2. The system of claim 1, wherein the holding unit has an interior in which at least a portion of the reservoir is received, when the holding unit is holding the reservoir, and wherein the transfer guard is located outside of the interior of the holding unit when the holding unit is holding the reservoir.

3. The system of claim 1, the vibrator being 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.

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, wherein the first holder and the second holder are connected to the vibrator.

6. The system of claim 1, the holding unit being 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.

7. 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 transfer guard providing a fluid path for transferring fluidic media from a vial to the reservoir when the holding unit is holding the reservoir;

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

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;

wherein the transfer guard and the reservoir are removable from the holding unit upon the reservoir being at least partially filled with the fluidic media.

8. 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 transfer guard providing a fluid path for transferring fluidic media from a vial to the reservoir when the holding unit is holding the reservoir, and

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

wherein the transfer guard and the reservoir are removable from the holding unit upon the reservoir being at least partially filled with the fluidic media; and

wherein the holding unit is 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.

9. A method for transferring fluidic media, comprising:
