DETAILED DESCRIPTION OF THE INVENTION
[0059] With reference to FIG. 1 is shown a prefilled drug delivery device 1 having a longitudinal axis A. The prefilled drug delivery device 1 comprises a container 2 for receiving the drug 3 to be injected. In the example shown in FIG. 1, the container 2 comprises at its distal end a distal tip 8 bearing a needle 4. In the example shown, the needle 4 is directly born by the distal tip 8. The container 2 is closed at its proximal end by a stopper 5. In the before-use storage configuration of the drug delivery device 1, as shown in FIG. 1, the needle 4 is covered by a shield 6 so as to protect it from outside contamination and so as to ensure tightness with the drug 3 contained into the container 2. The shield 6 further protects the user from accidental needle-stick injuries. The shield 6 is preferably made from a rigid material. Suitable materials for forming the shield 6 may be selected from polyethylene, polypropylene, polycarbonate and/or combinations thereof. The shield 6 may further comprise a part made of a soft material such as rubber, elastomeric polymer and/or combinations thereof.
[0060] In the example shown, a piston rod 7 is attached to the stopper 5. In embodiments not shown, the piston rod could be separate from the stopper 5.
[0061] In the example shown in FIG. 1, the proximal end 6a of the shield 6 is attached to the distal tip 8 of the drug delivery device 1. Moreover, the container 2 is provided at its proximal end with a flange 9. The flange 9 may help the user hold the drug delivery device 1 with the index and middle fingers while his thumb is pushing on the piston rod 7.
[0062] With reference to FIG. 2, is shown a first embodiment of a packaging 10 of the invention. The packaging 10 comprises a support 11 and an envelope 12. The envelope 12 is shaped and dimensioned so as to enclose the prefilled drug delivery device 1 before use, when the shield 6 is received within first holding means or a first holding element described below, as well as to enclose the drug delivery device 1 after use, when at least a distal part of the needle is received within second holding means or a second holding element further described below.
[0063] The envelope 12 preferably extends proximally from the support 11 along a longitudinal axis B.
[0064] The envelope 12 preferably comprises: [0065] An open distal end 20 closed by the support 11, [0066] A proximal end 21 which is closed, [0067] A front side 22, and [0068] A back side 23.
[0069] In embodiments, instructions for use may be printed on the front side 22 of the envelope 12 or on a label attached to the front side of the envelope 12. Alternatively, instructions for use may be folded and inserted into the packaging such as shown on FIG. 14. Although not shown, the packaging 10 may further include medical items such as for example anesthetic pads, alcohol swabs or sticky plasters, that may be located within the envelope.
[0070] The packaging 10 is preferably configured to be:
[0071] open so a user may have access to the drug delivery device located within the packaging, and/or
[0072] closed to prevent access to a drug delivery device located within the packaging.
[0073] To that purpose, according to one embodiment, the envelope may be removably attached to the support. According to this embodiment, the envelope forms a removable closure from the support, the envelope being configured to be:
[0074] either attached to the support in order to form with the support a pouch enclosing the drug delivery device when it is at least partially inserted into one of the first or second holding means, or one of the first or second holding elements, of the support; or
[0075] removed from the support.
[0076] According to an embodiment, the envelope may be permanently fixed to the support. In such an embodiment, the envelope comprises an opening 13 allowing access to the drug delivery device enclosed into the envelope. In embodiments, the opening 13 is a resealable opening.
[0077] According to the embodiment of FIGS. 2-6, the envelope 12 may comprise a rigid part and a flexible part. For example, as represented on FIG. 2, the envelope 12 may comprise a rigid frame 24 supporting a flexible film 25. For example, the rigid frame 24 may present a U-shaped body supporting a front part 26 of the flexible film 25 closing the front side 22 of the envelope 12 and a back part 27 (see FIGS. 5 and 6) of the flexible film 25 closing the back side 23 of the envelope 12. Alternatively, in embodiments not shown, the envelope may comprise a rigid shell and an opening lid attached to the rigid shell via a hinge. Alternatively, the envelope may comprise a back rigid shell and a front flexible film. The flexible film may be for example a plastic film, such as a polypropylene film or a polyethylene film.
[0078] With reference to FIGS. 2-6, the support 11 has the shape of a rigid shell. The rigid shell has a bottom wall 11a. Suitable materials for forming the rigid shell may be selected from polypropylene, polyoxymethylene, polycarbonate, acrylonitrile butadiene styrene and/or combinations thereof.
[0079] With reference to FIGS. 2-6, the support 11 is configured so as to be able to stand in a substantially stable position when positioned on a horizontal surface, so that the drug delivery device 1 extends substantially vertically when it is at least partially inserted into one of the first or second holding means, or one of the first or second holding elements, of the support, as will appear from the description below.
[0080] The support 11 comprises first holding means or first holding element configured for receiving at least part of the shield 6 of a prefilled drug delivery device 1, such as the one shown in FIG. 1. The first holding means or first holding element may be configured to retain the shield of the drug delivery device when the drug delivery device is pulled out from the support. The first holding means or first holding element are then configured to remove the shield from a drug delivery device. To that purpose, the first holding means or first holding element may comprise a first cavity configured to receive the shield and first gripping means or first gripping element configured to retain the shield within the cavity.
[0081] On the example shown on FIGS. 3 and 4, the first holding means or first holding element comprise a first cavity 14a defined by an elongate casing 14 extending proximally from the support 11 along a first longitudinal axis C, the first cavity 14a being shaped and dimensioned so as to be capable of receiving the shield 6 of the prefilled drug delivery device 1, such as the one shown in FIG. 1, before use.
[0082] The distal end of the elongate casing 14 is closed by the bottom wall 11a as shown on FIG. 4. In the example shown, the elongate casing 14 has a cylindrical shape and is fixed to the bottom wall 11a of the rigid shell 11 in a permanent way. The elongate casing 14 is provided at its proximal end with flexible legs 15 provided with an inner rim 16. The shield 6 may therefore be retained within the first cavity 14a thanks to the flexible legs 15 being snap-fitted onto said proximal end of said shield 6.
[0083] The support 11 further comprises second holding means or second holding element configured for receiving at least a distal part of the needle and optionally a distal part of the distal tip after use, preferably permanently. To that purpose, the second holding means or second holding element preferably comprise a second cavity configured to receive the needle and a distal part of the distal tip and second gripping means or second gripping element configured to retain the needle and at least a part of the distal tip within the second cavity.
[0084] On the example shown on FIGS. 2-6, the second holding means or second holding element comprise a second cavity 17a, defined by an elongated lodging 17 extending proximally from the support 11 along a second longitudinal axis D, the second cavity 17a being shaped and dimensioned so as to be capable of receiving the used needle 4 and a distal part of the distal tip 8 of the drug delivery device 1 after use. On the example shown, the elongated lodging 17 has a cylindrical shape and is provided at its proximal end with radial flexible tongs 18 forming second gripping means or second gripping element for retaining the used needle and the distal tip 8 inside the elongated lodging 17 after use. In particular, the flexible tongs 18 may retain the distal tip 8 inside the elongated lodging 17 by friction-fit engagement or retention teeth engagement.
[0085] With reference to FIG. 4, the second cavity 17a comprises an inner plug 19 in which the distal end of the needle 4 may be embedded.
[0086] Suitable materials for forming the inner plug 19 may be selected from rubber, elastomeric polymers and/or combinations thereof.
[0087] The presence of the inner plug 19 allows maintaining the used drug delivery device 1 in a stable position once repositioned into the packaging 10.
[0088] In the example shown in FIGS. 3 and 4, the first cavity 14a and the second cavity 17a are located close to each other and their longitudinal axes are parallel to each other, in the support 11. The packaging 10 is therefore compact. Moreover, as appears from FIGS. 3 and 4, the proximal end of the elongate casing 14 extends beyond the proximal end of the elongated lodging 17 in the proximal direction and further extends beyond the proximal end of the support 11 in the proximal direction.
[0089] With reference to FIGS. 2-6, the use of the packaging 10 will now be described.
[0090] With reference to FIG. 2, the packaging 10 is shown before use. The shield of the drug delivery device 1 is retained within the first cavity 14a. The envelope 12 encloses the drug delivery device 1 and closes the packaging 10. As appears from this Figure, in the before-use position of this embodiment, the drug delivery device 1 extends substantially parallel to the longitudinal axis B of the packaging 10.
[0091] Once the user wishes to use the drug delivery device 1, he opens the envelope 12 via the opening 13. With reference to FIG. 5, the user then removes the drug delivery device 1 from the elongate casing 14, while the shield 6 remains retained within the first cavity 14a thanks to the flexible legs 15 being snap-fitted onto the proximal end of the shield 6. The user may pull on the drug delivery device 1 in the direction of the arrow F1 of FIG. 5 with one hand, while maintaining the support 11 with the other hand (not shown). The step of removing the shield from the needle is therefore facilitated for people suffering from arthritis for example. The needle is therefore uncovered and the user may use the device in order to proceed to the injection. In addition, since the proximal end of the elongate casing 14 extends beyond the proximal ends of the elongated lodging 17 and of the support 11, the risk that the drug delivery device 1 touch the support 11 and/or the elongated lodging 17 when the drug delivery device 1 is removed from the elongate casing 14 is reduced. The risk that the drug delivery device 1 be contaminated before injection is therefore decreased.
[0092] Once the injection is completed, the user may approach the distal end of the used needle to the elongated lodging 17, and insert at least a distal part of the needle inside the second cavity 17a and the inner plug 19, so as to embed the distal part of the needle therein. The distal end of the needle is therefore protected and accidental needle stick injuries are avoided. Moreover, the drug delivery device 1 is maintained in a stable position.
[0093] The user may then close the packaging by covering the used drug delivery device 1 with the envelope 12 and may reseal the opening 13. The user may then transport the used drug delivery device 1 safely until he is able to throw the whole packaging away in a specific container.
[0094] With reference to FIGS. 7-9 is shown a second embodiment of the packaging of the invention, in which the first longitudinal axis C and the second longitudinal axis D are inclined towards the central longitudinal axis B of the envelope and in which the support and the envelope form altogether a rigid case. Suitable materials for forming the rigid case may be selected from polypropylene, polyoxymethylene, polycarbonate, acrylonitrile butadiene styrene and/or combinations thereof.
[0095] The packaging 100 of FIGS. 7-9 comprises a support 111 and an envelope 112, both made of a rigid material. The support 111 may be closed by the envelope 112 by friction fit engagement of the support 111 in the envelope 112. On FIGS. 7-9, the packaging 100 is shown in a closed configuration and therefore forms a rigid case capable of receiving a prefilled drug delivery device in a before-use storage configuration and/or in an after-use storage configuration.
[0096] With reference to FIGS. 7-9, the support 111 comprises a first cavity 114a defined by an elongate casing 114 extending proximally from the support 111 along a first longitudinal axis C. The first cavity 114a is configured to receive the shield 6 of the drug delivery device 1 in a before-use storage configuration of the drug delivery device 1, as shown in FIG. 8. The distal end of the elongate casing 114 is closed by a wall 111a of the support 111 and is therefore fixed to the support 111 in a permanent way. In the example shown, the elongate casing 114 has a cylindrical shape and is provided at its proximal end with flexible legs 115 provided with an inner rim 116. With reference to FIG. 8, the drug delivery device 1 is in its before-use storage configuration and is inserted in the support 111 via its shield 6 being retained within the first cavity 114a thanks to the flexible legs 115 being snap-fitted onto the proximal end 6a of the shield 6.
[0097] Still with reference to FIGS. 7-9, the support 111 comprises a second cavity 117a defined by an elongated lodging 117 extending proximally from the support 111 along a second longitudinal axis D. The second cavity 117a is shaped and dimensioned so as to be capable of receiving the used needle 4 and a distal part of the distal tip 8 of the drug delivery device 1 after use. On the example shown, the elongated lodging 117 has a cylindrical shape and extends from the wall 111a of the support 111. The elongated lodging 117 is provided at its proximal end with radial flexible tongs 118. At the distal end of the elongated lodging 117, the wall 111a of the support 111 is provided with an open channel 111b allowing the distal end of the second cavity 117a to communicate with the exterior of the packaging 100.
[0098] The second cavity 117a further includes an inner plug 119. The inner plug 119 is preferably made of a soft material such as rubber or an elastomeric polymer. In the example shown, the distal end of the inner plug 119 is provided with a protruding part, under the form of a peg 120. As will appear later in the description, the inner plug 119 is configured so as to be capable of sliding within the second cavity 117a along the second longitudinal axis D, and the peg 120 is shaped and dimensioned so as to be capable of circulating within the open channel 111b. In a before-use position of the packaging 100 or in the before-use storage configuration of the drug delivery device 1, the peg 120 is contained within the second cavity 117a and is neither visible nor feelable by a user.
[0099] With reference to FIG. 9, in the after-use storage configuration of the drug delivery device 1, the whole needle 4 and a distal part of the distal tip 8 of the drug delivery device 1 are received in the second cavity 117a. The distal part of the needle 4 is embedded in the inner plug 119. Moreover, the flexible tongs 118 retain the distal tip 8 inside the second cavity by 117a friction-fit engagement or retention teeth engagement.
[0100] In addition, the inner plug 119 has been pushed distally in the second cavity 117a, upon the pressure exerted by the distal tip 8 of the drug delivery device 1 coming in contact with a proximal end of the inner plug 119, thereby causing the peg 120 to move from a retracted position located within the second cavity 117a, as shown in FIG. 7 or 8, to an exposed position, at a distal end of the open channel 111b and close to the exterior of the packaging 100, where said peg 120 may be seen and/or felt by a user, as shown in FIG. 9.
[0101] As appears from FIGS. 7-9, the proximal end of the elongate casing 114 extends beyond the proximal end of the elongated lodging 117 in the proximal direction and further extends beyond the proximal end of the support 111 in the proximal direction.
[0102] As appears from FIG. 7, the envelope 112 extends proximally from the support 111 along a central longitudinal axis B. The first and second cavities (114a, 117a) are located on either side of a plane including the central longitudinal axis B. The first longitudinal axis C of the first cavity 114a and the second longitudinal axis D of the second cavity 117a are both inclined towards the central longitudinal axis B. As will appear from the description below, such an arrangement of the first and second cavities (114a, 117a) allow the drug delivery device 1 to be held sufficiently away from a wall of the envelope 112 when said drug delivery device 1 is stored within the packaging 100.
[0103] With reference to FIGS. 8-9, the use of the packaging 100 will now be described.
[0104] The packaging 100 is provided to a user in the before-use storage configuration of the drug delivery device 1, as shown in FIG. 8. The drug delivery device 1 is inserted in the support 111 via its shield 6 being retained within the first cavity 114a with the flexible legs 115 snap-fitted onto a proximal end 6a of the shield 6. In this configuration, the longitudinal axis A of the drug delivery device 1 and the first longitudinal axis C of the first cavity 114a are confounded. As a result, a proximal end of the container of the drug delivery device 1 is substantially located on the central longitudinal axis B of the envelope 112. As appears from FIG. 8, the drug delivery device 1 is as a consequence maintained at a certain distance away from the walls of the envelope 112. Moreover, the drug delivery device 1 is maintained in a stable position thanks to its shield 6 being safely secured within the first cavity 114a.
[0105] The user is therefore ensured that the drug delivery device 1 has not been in contact with the walls of the envelope 112 during the storage and that potential contamination of the drug delivery device has been avoided.
[0106] In this position also, the peg 120 is in a retracted position, within the second cavity 117a, where it is hidden from the view of the user.
[0107] When the user is ready to proceed to the injection, he may open the rigid case formed by the support 111 and the envelope 112 by removing the envelope 112 from the support 111. The user then removes the drug delivery device 1 from the first cavity 114a, while the shield 6 remains retained within said first cavity 114a thanks to the flexible legs 115 being snap-fitted onto the proximal end 6a of the shield 6. The user may pull on the drug delivery device 1 with one hand, while maintaining the support 111 with the other hand. The step of removing the shield 6 from the needle 4 is therefore facilitated for people suffering from arthritis for example. The needle 4 is therefore uncovered and the user may use the device in order to proceed to the injection. In addition, since the proximal end of the elongate casing 114 extends beyond the proximal ends of the elongated lodging 117 and of the support 111, the risk that the drug delivery device 1 touch the support 111 and/or the elongated lodging 117 when the drug delivery device 1 is removed from the elongate casing 114 is reduced. The risk that the drug delivery device 1 be contaminated before injection is therefore decreased.
[0108] Once the injection is completed, the user may approach the distal end of the used needle 4 towards the second cavity 117a. The user inserts the needle 4 inside the second cavity 117a and inside the inner plug 119 so as to embed the needle 4 therein. During this step, the distal end of the distal tip 8 comes in contact with the proximal end of the inner plug 119. While the user continues to push distally on the drug delivery device 1, the distal end of the distal tip 8 pushes the inner plug 119 which is caused to slide distally within the second cavity 117a. As a result, the peg 120 is caused to move distally and enters the open channel 111b of the wall 111a of the support 111.
[0109] As shown in FIG. 9, when the drug delivery device 1 is in its after-use storage configuration, the peg 120 protrudes outside the open channel 111b and becomes visible and feelable to the user. The peg 120 has therefore moved from its retracted position to its exposed position. In this configuration, the distal end of the needle 4 is protected and accidental needle stick injuries are avoided. Moreover, the drug delivery device 1 is maintained in a stable position thanks to the flexible tongs 118 retaining the distal part of the distal tip 8 within the second cavity 117a.
[0110] The user may then close the packaging 100 back by covering the used drug delivery device 1 with the envelope 112 and fit the envelope 112 on the support 111. In this configuration, as shown in FIG. 9, the longitudinal axis A of the drug delivery device 1 and the second longitudinal axis D of the second cavity 117a are confounded and a proximal end of the container of the drug delivery device 1 is substantially located on the central longitudinal axis B of the envelope 112, thereby allowing the used drug delivery device 1 to be maintained at a certain distance away from the walls of the envelope 112.
[0111] The arrangement of the first and second cavities (114a; 117a) in the support 111, with their respective longitudinal axes (C, D) inclined towards the central longitudinal axis B of the envelope 112 allows the drug delivery device 1 to be held sufficiently away from a wall of the envelope 112 when said drug delivery device 1 is stored within the packaging, while rendering the packaging 100 compact and easy to transport. In particular, the inclination of the elongate casing 114 and/or of the elongated lodging 117 allows obtaining a compact radial design for the packaging 100, even if the drug delivery device 1 stored therein comprises an extended flange.
[0112] The user may therefore transport the used drug delivery device 1 in the rigid case formed by the support 111 and envelope 112 safely until he is able to throw the whole packaging 100 away in an appropriate container.
[0113] The envelope of the packaging may further comprise information such as instructions for use.
[0114] With reference to FIG. 14, is shown the packaging 100 of FIGS. 7-9, further comprising a sheet 130, for example made of paper. The sheet 130 may contain information such as instructions for use. In the before-use storage configuration of the drug delivery device 1, the sheet 130 is folded on itself and over the piston rod 7 of the drug delivery device 1, so that it is made directly available to the user when the user proceeds to the opening of the packaging 100 as shown on FIG. 14. For example, the sheet 130 may be folded in a way so that said sheet 130 pops up from the packaging 100 when the user removes the envelope 112 from the support 111. The use of the packaging is therefore facilitated for the user, who will not waste time searching for the instructions for use.
[0115] With reference to FIGS. 15 and 16, is shown the packaging of FIGS. 7-9, further comprising a sheet 140, for example made of paper. The sheet 140 may contain information such as instructions for use. In the before-use storage configuration of the drug delivery device 1, the sheet 140 is folded on itself in a concertinaed way and sandwiched between a proximal end 7a of the plunger rod 7 and an inner surface of a proximal wall 112a of the envelope 112. A first glue dot 141 links a proximal end 140a of the folded sheet 140 to the inner surface of the proximal wall 112a. A second glue dot 142 links a distal end 140b of the folded sheet 140 to the proximal end 7a of the piston rod 7. The first glue dot 141 shows an attachment force greater than that of the second glue dot 142. As a result, when the user pulls on the envelope 112 in a view of opening the packaging 100, the sheet 140 slowly unfolds as its proximal end 140a remains attached to the inner surface of the proximal wall 112a of the envelope 112 and its distal end 140b is drawn in the distal direction together with the piston rod 7, as shown on FIG. 15. When the sheet 140 is completely unfolded, the user releases the second glue dot 142 from the plunger rod, as shown in FIG. 16. The user may then remove completely the sheet 140 from the envelope 112 by keeping on pulling on the distal end 140b of the sheet 140, until the first glue dot 141 comes off and separates from the inner surface of the proximal wall 112a of the envelope 112. The use of the packaging is therefore facilitated for the user, who will not waste time searching for the instructions for use.
[0116] With reference to FIGS. 10 and 11, are shown partial views of an alternative embodiment of a packaging 200 of the invention, when the distal tip 208 of the drug delivery device 201 is free of any needle in the before-use storage configuration of the drug delivery device 201. In such embodiments, the shield 206 of the drug delivery device 201 may be formed from a soft material, such as a rubber or an elastomeric polymer.
[0117] As shown in FIG. 10, the shield 206 covers the distal tip 208 of the drug delivery device 201 and is received within the first cavity 214a of the support 211 of the packaging 200 when the drug delivery device 201 is in its before-use storage configuration. The shield 206 may be retained within the first cavity 214a by means of flexible legs 215 forming first gripping means or first gripping element.
[0118] In such embodiments, the packaging 200 may therefore further comprise a needle hub 220, as shown in FIG. 11. The needle hub 220 comprises a hub 221 bearing a needle 4 and a proximal sleeve 222 defining a conical recess 223 configured to be fitted onto the distal tip 208.
[0119] In such embodiments, when the user is ready to proceed to the injection, he may remove the drug delivery device 201 from the first cavity 214a while the shield 206 remains retained within said first cavity 214a thanks to the flexible legs 215 being snap-fitted onto the shield 206. The user has therefore in hands a drug delivery device 201 provided with a distal tip 208 free of any needle. The user may then grasp the needle hub 220 provided in the packaging 200 and mount said needle hub 220 onto the distal tip 208 by fitting the conical recess 223 onto said distal tip 208. The user is thereby provided with a drug delivery device 201 provided with a needle 4 and he may proceed to the injection.
[0120] Once the injection is completed, the user may simply insert the used needle into the second cavity (not shown) in the same manner as described in the above description for embodiments of FIGS. 2-9, without having to remove the needle hub 220 from the distal tip 208.
[0121] With reference to FIG. 12 is shown an alternative embodiment of a first cavity 314a of a support 311 of a packaging 300 of the invention in which the first gripping means or first gripping element retain the shield 306 of the drug delivery device (not shown) fixed to said first cavity 314a thanks to a cooperation with a distal end of said shield 306.
[0122] With reference to this Figure, the first cavity 314a is defined by a port 314 comprising flexible legs 315. The shield 306 is provided with a distal outer rim 306a. As shown in this Figure, in the before-use storage configuration of the drug delivery device, the flexible legs 315 are snap-fitted onto the distal outer rim 306a of the shield 306, thereby forming first gripping means or first gripping element retaining the shield 306 fixed to the cavity 314a.
[0123] With reference to FIG. 13, is shown an alternative embodiment of a second cavity 417a of a support 411 of a packaging 400 of the invention in which the second gripping means or second gripping element are configured for being snap-fitted onto the needle 4. With reference to this Figure, the second cavity 417a is defined by an elongated lodging 417 configured for receiving at least a distal part of the needle 4. The elongated lodging 417 is provided at its proximal end with flexible legs 418 provided with inner rims 418a. The flexible legs 418 and their inner rims 418a are made of a flexible metal allowing and are capable of being snap-fitted to the needle 4 so as to retain said needle 4 within the second cavity 417.
[0124] The packaging of the invention allows safely storing and transporting a prefilled drug delivery device, before and after use.
