It will thus be appreciated that aspects and features of apparatus and methods discussed herein which are not described in detail may be implemented in accordance with any conventional techniques for implementing such aspects and features.

[0056] Exemplary embodiments of the present invention provide an adapter for a fluid transfer device as shown in FIGS. 1-5. In use, adapter 150 may facilitate the use of pen 100 with a fluid transfer device. Specifically, adapter 150 may couple to pen 100, which stores a specific amount of a drug in fluid form. Adapter 150 may allow for pen 100 to be used with a fluid delivery device, such as the Ez Fill product. In use, adapter 150 may be placed within the vial receptacle of the Ez Fill product. Adapter 150 may allow pen 100 to align with a needle of the Ez-Fill product to allow the needle to puncture septum 160 of pen 100. When the transfer of the fluid from pen 100 to the desired vial via the Ez-Fill product is completed, pen 100 and adapter 150 may be removed from the Ez-Fill product. Adapter 150 may be configured to not be removable from pen 100. Further, Adapter 150 may be configured to prevent the coupling of a needle to pen 100, thereby preventing pen 100 from being used to directly inject the fluid stored in pen 100.

[0057] Referring to FIG. 1, adapter 150 may be configured to couple to a first fluid storage device, such as pen 100. Fluid storage device/pen 100 may store a specific amount of a drug. For example, pen 100 may store insulin that is to be injected into a user. Pen 100 may include proximal end 100b and distal end 100a. Distal end 100a may in some embodiments include a cover 101 when the fluid storage device/pen 100 is not in use, and may include a tip 102, which may be configured to couple to a needle or other device for transferring the fluid from pen 100 to the user or another storage container. Where a cover 101 is provided, the cover 101 may in accordance with some embodiments comprise an attachment means 101a, such as a resilient clip, for attaching the fluid storage device 100 to another object (e.g. a user's shirt pocket). During the operation of fluid storage device/pen 100, the cover 101 may be first removed to expose the tip 102. Distal end 100a of the fluid storage device/pen 100 may further include septum 160. Septum 160 may be punctured by a needle to allow for the fluid stored within pen 100 to be transferred to another device. Septum 160 may be configured to prevent the fluid stored within pen 100 from exiting pen 100 unless septum 160 is punctured. Tip 102 may include threads 190, which allow pen 100 to be coupled to a syringe or other device. Adapter 150 may be configured to couple to pen 100 such that adapter 150 is disposed around distal end 100a. Adapter 150 may include first end 175, second end 180, side wall 185, and retaining member 170. First end 175 may include a first cylinder which may include aperture 165. Aperture 165 may be configured to receive distal end 100a and tip 102 of pen 100. In some embodiments, side wall 185 is disposed around distal end 100a when distal end 100a and tip 102 are received by aperture 165. Aperture 165 may have a diameter larger than the diameter of retaining member 170. Second end 180 may include a second cylinder. In some embodiments, the first cylinder of first end 175 may taper down to the second cylinder of second end 180. First end 175 and second end 180 may be open on both ends creating through-bore 172. In some embodiments, retaining member 170 may be configured to engage with threads 190 of tip 102 to couple adapter 150 to pen 100. Retaining member 170 may include barbs 155. Barbs 155 may be configured to engage with threads 190 to allow pen 100 to be only rotated in one direction relative to adapter 150. For example, barbs 155 of retaining member 170 may be oriented to allow pen 100 to be rotated in only one direction for coupling adapter 150 to pen 100, preventing adapter 150 from being removed from pen 100 once coupled together. Barbs 155 may be oriented to be angled downwards away from tip 102 when retaining member 170 is being coupled to pen 100. Barbs 155 may engage with threads 190 to prevent adapter 150 from being removed from pen 100 by preventing rotation of pen 100 relative to adapter 150 in the direction necessary for removal of adapter 150 from pen 100. In some embodiments, adapter 150 remains permanently coupled to pen 100 and disposed of when pen 100 is disposed of. In alternative embodiments, a special tool may be used to remove adapter 150 from pen 100. In some embodiments, barbs 155 are a separate assembly component.

[0058] Referring to FIG. 2, there is shown a second embodiment of the adapter, generally designated 250. Adapter 250 is similar to the first embodiment of adapter 150 except that adapter 250 includes retaining member 270 instead of retaining member 170. Retaining member 270 may include integrated barbs 255, which may be integrated with threads 245 of adapter 250. Integrated barbs 255 may be formed with the molding of retaining member 270 or other fabrication of the retaining members 270. In some embodiments, integrated barbs 255 are oriented such that they are angled downwards when adapter 250 is coupled to pen 100. Integrated barbs 255 may be configured to engage with threads 190 when adapter 250 is pulled in a direction away from tip 102 of pen 100, preventing adapter 250 from becoming de-coupled from tip 102. In some embodiments, adapter 250 remains permanently coupled to pen 100 and disposed of when pen 100 is disposed of. In alternative embodiments, a special tool may be used to remove adapter 250 from pen 100. In some embodiments, integrated barbs 255 are a separate assembly component.

[0059] Referring to FIG. 3, there is shown a third embodiment of the adapter, generally designated 350. Adapter 350 is similar to the first embodiment of adapter 150 except that adapter 350 includes retaining member 370 instead of retaining member 170. Retaining member 370 may include attached barbs 355. In some embodiments, attached barbs 355 are a separate assembly component. Attached barbs 355 may be formed of a separate material inserted into a provided space within retaining member 370. Attached barbs 355 may be oriented such that they are angled down when adapter 350 is coupled to pen 100. Attached barbs 355 may be configured to engage with threads 190 when adapter 350 is attempted to be pulled away from tip 120 of pen 100. In some embodiments, adapter 350 remains permanently coupled to pen 100 and disposed of when pen 100 is disposed of. Attached barbs 355 may be comprised of a metal such as steel, stainless steel, nickel, brass, Nitinol or a plastic such as poly(phenylene sulfide) (PPS), polyetheretherketone (PEEK), polyether ketones (PEK), Polysulfone (PSU), poly(ethersulfone) (PES), polyetherimide (PEI), cyclo olefin polymer (COP), polycarbonate, or composites such as fiber filled materials including thermoplastics and thermosets such as epoxies.

[0060] In some embodiment, if enough force is applied to adapter 150, 250, or 350 in an attempt to remove them from tip 102, extensive damage may be done to threads 190 preventing a needle or other device from being coupled to tip 102 of pen 100.

[0061] Referring to FIG. 4, there is shown a fourth embodiment of the adapter, generally designated 450. Adapter 450 is similar to the first embodiment of adapter 150 except that adapter 450 includes retaining member 470 instead of retaining member 170. Retaining member 470 includes inner ring 430 and outer housing 420. Inner ring 430 may be disposed within outer housing 420 may include threads 437, which may be configured to mate with threads 190 of pen 100. In some embodiments, inner ring 430 is configured to only rotate in one direction. When adapter 450 is being coupled to tip 102, inner ring 430 may be locked with outer housing 420 and thus does not rotate relative to outer housing 420. This allows threads 437 of inner ring 430 to engage with threads 190 of tip 102. Rotating tip 102 of pen 100 in the opposite direction to attempt to remove pen 100 from adapter 450 results in inner ring 430 rotating within outer housing 420, thereby preventing pen 100 from de-coupling with adapter 450. Pen 100 is prevented form de-coupling from adapter 450 since instead of rotating relative to inner ring 430, inner ring 430 and pen 100 rotate together, preventing pen 100 from disengaging with inner ring 430, and thus adapter 450

[0062] In some embodiments, outer housing 420 may include pawl features 425, and inner ring 430 may include catch features 435. Catch features 435 may be disposed on an exterior surface of inner ring 430 and may be configured to engage with pawl features 425 of outer housing 420. In some embodiments, outer housing 420 may include catch features 435, and inner ring 430 may include pawl features 425. In some embodiments, the rotational force of coupling inner ring 430 to tip 102 is transferred through pawl features 425 to catch features 435. When adapter 450 is rotated to couple to tip 102 of pen 100, pawl features 425 engage with catch features 435 thereby locking inner ring 430 with outer housing 420. When the rotation is reversed in an attempt to de-coupled adapter 450 from tip 102, pawl features 425 do not engage with catch features 435 and thus inner ring 430 rotates with tip 102 relative to outer housing 420, preventing inner ring 430 from de-coupling from tip 102 of pen 100. For example, pawl features 425 of outer housing 420 and catch features 435 of inner ring 430 may engage with each other in a relative clockwise motion, but may slip past each other in relative counter-clockwise motion. In some embodiments, pawl features 425 and catch features 435 may be complementary ratchet teeth axially stacked or concentric to each other.

[0063] Referring to FIG. 5, there is shown a fifth embodiment of the adapter, generally designated 550. Adapter 550 may include transfer element 552. Transfer element 552 may be configured to transfer the fluid from pen 100 to a vial or other container with a septum seal. For example, transfer element 552 may be a continuous needle to transfer the fluid stored within pen 100 to a vial (not shown). Adapter 550 may also include concentric outer needle 555 surrounding the lower part of transfer element 552. In some embodiments, extended side wall 554 may be configured to shield transfer element 552 from a user to prevent injury. Pen 100 may be screwed into the threads 510. Adapter 550 may be placed over the neck of a vial with side wall 554 surrounding the vial seal and the ends of transfer element 552 and concentric outer needle 555. The user depresses a button located on pen 100, forcing the contents of pen 100 through transfer element 552 into the receiving vial while the air from the vial can egress/escape through the annular space between transfer element 552 and concentric outer needle 555 via port 559. Once the liquid is transferred, the vial can be used in any system that utilizes the vial format. Port 559 may include a fluid trap or filter to prevent over fill from escaping. Port 559 may include a filter to prevent odor from escaping. Port 559 may include a variable volume chamber to trap excess fluid without creating an increase in the system pressure.

[0064] Referring to FIG. 6, there is shown a sixth embodiment of the adapter, generally designated 650. Adapter 650 may include first end 652, second end 654, and inner ring 660. As with a number of the previous embodiments, first end 652 and second end 654 may be open on both ends creating through-bore 672. First end 652 may be flared and may have an outer diameter greater than the outer diameter of second end 654. In some embodiments, the outer diameter of first end 652 may be greater than the outer diameter of pen 100. First end 652 may include a first cylinder that tapers down to a second cylinder. Second end 654 may be cylindrical in shape and may be in open communication with first end 652. Second end 654 may include engagement features 656. Engagement features 656 may be configured to engage with locking features 658 of inner ring 660.

[0065] Inner ring 660 may be configured to sit within second end 654, whereby a portion of the second end 654 forms an outer housing 620, against which the inner ring 660 engages. In the embodiment shown in FIG. 6, an end wall 659 of the inner ring 660 is configured to sit on an inwardly projecting shoulder 621 of the outer housing 620. Inner ring 660 may include threads 662 which mate with threads 190 of pen 100. In some embodiments, inner ring 656 is configured to only rotate in one direction. When adapter 650 is being coupled to tip 102, engagement features 656, such as ratchet teeth located on the inwardly projecting shoulder 621 (as shown in the embodiment of FIG. 6), may engage with locking features 658, such as complementary ratchet teeth located on the end wall 659 of the inner ring 660 (as shown in the embodiment of FIG. 6), to lock inner ring 660 with second end 654 and preventing rotation of inner ring 660 relative to adapter 650. This allows threads 662 of inner ring 656 to engage with threads 190 of pen 100. Rotating pen 100 in the opposite direction to attempt to remove pen 100 from adapter 650 results in inner ring 660 rotating within second end 654, as engagement features 656 no longer engage with locking features 658. When inner ring 660 is coupled to pen 100 and allowed to rotate relative to adapter 650, pen 100 cannot be de-coupled from adapter 650.

[0066] Referring to FIGS. 7A-7C, adapter 650 may be used with fluid transfer device 800. Fluid transfer device 800 may include slot 700 and members 702, alongside a needle 704 (shown in FIG. 6) if applicable for piercing any septum 160 from the fluid storage device/pen 100. Slot 700 may be configured to move between an open position or closed position to allow access to fluid transfer device 800. Slot 700 may be biased to remain in a closed position using a biasing member, such as a spring. For example, as illustrated in 7A, slot 700 may be in a closed position preventing access to opening 704. In some embodiments, the flared configuration of first end 652 may engage one or more actuation members 702, which in the particular embodiment of FIG. 7 are shown as one or more actuation projections, as adapter 650 enter slot 700 of fluid transfer device 800. Referring to FIG. 7B, the flared configuration of first end 652 causes the actuation members 702 to separate from each other as adapter 650 is moved proximate to fluid transfer device 800, thereby opening slot 700. As first end 652 engages with actuation members 702 and causes them to be moved apart relative to each other, slot 700 may open to allow adapter 650 to enter opening 704. In the particular embodiment of FIG. 7B, it can be seen that the actuation members 702 may notionally extend around a circumference/perimeter of the slot 70. In this way, the slot can be actuated from a number of different positions around the slot using the different actuation members 702 located around the slot 700. Referring to FIG. 7C, adapter 650 has been fully inserted into opening 704 through slot 700 as members 702 are fully spaced apart due to engagement with the flared configuration of first end 652. Although the embodiment from FIGS. 7A-7C comprise more than one actuation member, it will be appreciated that in some other embodiments that there may be only one actuation member 702 provided/needed for moving the slot 702 from its closed position to its open position.
