     BACKGROUND 
     A refillable pump device which can accurately dispense multiple fluids has applications which span a wide variety of fields. For example, a refillable pump device could be used for the delivery of multiple pharmaceutical agents in the medical device industry, for the delivery of multiple part adhesives in the chemical industry, for the simultaneous delivery of colorants, seasonings, or preservatives during food products manufacturing, or the like. Although these applications do not represent the complete range of potential uses for a refillable pump device which can accurately dispense multiple fluids they are representative of applications for which, e.g., control of a volumetric flow rate of each individual fluid being delivered may be important. 
     In the context of drug or medicament delivery from multiple reservoirs, the possibility for human error exists as a user refills a multiple fluid pump device. In such a case, for example, a user incorrectly refilling the internal reservoirs of the pump device can result in an improper drug or medicament dosing for the user. In order to minimize the potential for these and other problems, what is needed are both (a) reliable refilling methods and (b) appropriate mechanical interfaces at each appropriate port of the reservoirs of a pump device or cartridge thereof as well as at each appropriate port of the external reservoir.

     DETAILED DESCRIPTION 
     As discussed above, a refillable pump device which can accurately dispense multiple fluids has applications which span a wide variety of fields. The ability of the refillable pump device to dispense multiple fluids (including liquids and/or gasses) may require multiple internal reservoirs within the pump device, each with distinguishable input and output ports in some cases. The input port for each internal reservoir may serve as an access site via which a user can refill the given internal reservoir. In turn, the output port for each internal reservoir may serve as a means by which a liquid or gas can exit the pump device and be delivered to a target area. Alternatively, either output port may be used in order to refill the respective internal reservoir in fluid communication with respectively therewith. 
     In the case where the refillable pump device is used as a medical device for the delivery of multiple agents or medicaments, including, e.g., multiple pharmaceutical or bioactive agents wherein different volumetric doses of the different agents may be delivered to a patient or caregiver, then the proper refilling of each internal reservoir of the pump device by the user may be particularly important. 
     When a pump device is activated, the volumetric flow rate of a fluid from each internal reservoir may be calibrated to deliver the appropriate distinguishable doses for each agent over a desired temporal period; e.g., the period during which the pump device is activated. For diabetic indications, the patient or caregiver is typically the user who refills the pump device with insulin or other suitable medications which may include Symlin®, Byetta®, Bydureon®, Victoza®, Glucagon®, saline, antibiotics, or any other suitable medications which may be delivered subdermally or by other suitable delivery methods. The patient or caregiver can refill the respective internal reservoirs of the pump device from a variety of different external reservoir configurations which can include drug vials, insulin pen vials, and insulin pen assemblies. 
     For a case where a pump device includes a disposable cartridge, it may be desirable to isolate agent reservoirs and agent ports in the cartridge which can detach from a body of the pump device. The ability of the user (e.g., the patient or caregiver) to detach the cartridge from the body of the pump device may allow, for example, cartridge replacement after a specified number of uses or after the agent has been partially or completely dispensed therefrom. The pump device body may contain features such as a fluid pumping mechanism, feedback control circuitry, and patient or caregiver user interface through which the pump device may be controlled. The accompanying cartridge may contain single or multiple agent reservoirs and a single or multiple input and output ports. In the case of a cartridge having multiple reservoirs, multiple input ports may be used in order to refill the multiple internal reservoirs, whereas the multiple output ports may be used to deliver multiple agents to the patient or caregiver. For some method embodiments, it may be desirable to refill one or more of the multiple internal reservoirs using one or more of the multiple output ports. 
     Transferring fluids from supply reservoirs such as, e.g., syringes, vials, and insulin pens to receptacle reservoirs such as, e.g., the internal reservoirs of a pump cartridge may be accomplished any number of methods. For instance, the fluid could be transferred from a supply reservoir to a receptacle reservoir by decreasing the fluid pressure within an interior volume of the receptacle reservoir with a pump device. The fluid could also be transferred from a supply reservoir into a receptacle reservoir by increasing the fluid pressure within an interior volume of the supply reservoir with a pump device. The fluid could also be transferred from a supply reservoir to a receptacle reservoir by decreasing an internal volume of the supply reservoir with a moveable plunger that is contained within the internal volume of the supply reservoir. The fluid also could be transferred from a supply reservoir to a receptacle reservoir by increasing the internal volume of the receptacle reservoir with a moveable plunger contained within the internal volume of the receptacle reservoir. 
       FIGS. 1-3B  illustrate an embodiment of a pump system including a multi-reservoir cartridge  10  having multiple input and output ports which can be inserted into the pump device in order to deliver multiple pharmaceutical agents to a patient or caregiver. For some embodiments, it may be possible for the pump device to simultaneously deliver different doses of the different agents to the patient or caregiver. In some cases, the patient or caregiver can refill the cartridge receptacle reservoirs with the different agents from multiple supply reservoirs. It may be desirable in some cases for the various ports of the supply reservoirs and receptacle reservoirs be configured such that the possibility of patient or caregiver filling a given receptacle reservoir with an agent from the wrong supply reservoir is mechanically prevented. 
       FIG. 1  is a perspective view a pump device embodiment  10  with a multiple reservoir cartridge embodiment  12  having multiple input and output ports. The multiple reservoir cartridge incorporates embodiments of a first input port  14 , a second input port  16 , a first output port  18 , and a second output port  20 .  FIG. 2  shows the pump device  10  of  FIG. 1  with the multiple reservoir cartridge  12  separated from the pump device body  22 .  FIG. 3  is a frontal view of the multiple reservoir cartridge  12  of  FIG. 2 .  FIG. 3A  is a transverse sectional view of the multiple reservoir cartridge  12  of  FIG. 3  showing the first input port  14  which is in fluid communication with a first pump reservoir  24 , and the second input port  16  which is in fluid communication with a second pump reservoir  26 .  FIG. 3B  is a transverse sectional view of the multiple reservoir cartridge  12  of  FIG. 3  showing the first output port  18  which is in fluid communication with the first pump reservoir  24 , and the second output port  20  which is in fluid communication with the second pump reservoir  26 . 
       FIG. 4  is a perspective view of a multiple reservoir cartridge  28  embodiment with a single input port and multiple output ports. The multiple reservoir cartridge  28  incorporates embodiments of an input port  30 , a first output port  32 , and a second output port  34 .  FIG. 5A  is a frontal view of the multiple reservoir cartridge  28  of  FIG. 4 .  FIG. 5B  is a transverse sectional view of the multiple reservoir cartridge  28  of  FIG. 5A  showing the input port  30  which is in fluid communication with a second pump reservoir  38 .  FIG. 5C  is a transverse sectional view of the multiple reservoir cartridge embodiment  28  of  FIG. 5A  showing the first output port  32  which is in fluid communication with a first pump reservoir  36 , as well as the second output reservoir  34  which is in fluid communication with the second pump reservoir  38 . 
     The multiple reservoir cartridges are distinguished by the configuration of each fluid interface port which is connected to each pump reservoir of the cartridge embodiment. A user may refill the pump reservoirs from multiple supply reservoirs with each fluid being delivered to its intended respective pump reservoir. Thus, the various fluid interface ports of the supply reservoirs and pump reservoirs may be mechanically configured such that the possibility of a user filling a given pump reservoir with an agent from the wrong supply reservoir is prevented.  FIGS. 6A-7B  illustrate such a fluid transfer system wherein multiple fluids may be transferred selectively from multiple supply reservoirs into the respective pump reservoirs of the multiple reservoir cartridge embodiment  28 . 
       FIGS. 6A and 6H  show the multiple reservoir cartridge  28  which may include a first pump reservoir  36  having a first pump reservoir body  40 , a first reservoir interior volume  42  disposed within the first pump reservoir body  40 , an input port  30  and a first output port  32 . The first pump reservoir body  40  may be fabricated from a thin flexible material. The input port  30  may include a reservoir septum  44  which is disposed within a multiple reservoir cartridge body  46 . The reservoir septum  44  may be configured to seal the first reservoir interior volume  42 . The first output port  32  is in fluid communication with the first reservoir interior volume  42 . The first output port  32  includes a first fluid line  48  which may be a flexible tube with an inner fluid lumen which connects the first reservoir interior volume  42  to a first output port adapter  52 . 
     The fluid transfer system may also include a second pump reservoir  38  of the multiple reservoir cartridge  28 , as illustrated in  FIGS. 6H and 6L . The second pump reservoir  38  may include a second pump reservoir body  54 , a second reservoir interior volume  56  disposed within a second pump reservoir body  54 , and a second output port  34  ( FIG. 6A ). The second pump reservoir body  54  may be fabricated from a thin flexible material. The second output port  34  may include a second output port adapter  60  which is in fluid communication with the second reservoir interior volume  56 . The second output port  34  may also include a second fluid line  50  which may be a flexible tube with an inner fluid lumen which connects the second reservoir interior volume  56  to the second output port adapter  60 . 
     The fluid transfer system may also include a syringe hub assembly  62  which is shown in  FIGS. 6C and 6E .  FIG. 6C  illustrates a syringe reservoir  64  and a hub assembly  66  in a decoupled state.  FIG. 6E  shows the syringe reservoir  64  coupled or releasable secured to the hub assembly  66  forming the syringe hub assembly  62 . The syringe hub assembly  62  may include a syringe body  68 , a syringe interior volume  70  disposed within the syringe body  68 , a first fluid  72  contained within the syringe interior volume  70 , and the hub assembly  66  which may be coupled to the syringe body  68 . As shown in  FIG. 6C , the syringe reservoir  64  has a syringe port  74  which may be in fluid communication with the syringe interior volume  70 . The syringe reservoir  64  also has a plunger  76 , which, when manipulated, can vary the volume of the syringe interior volume  70  and thereby draw a fluid into or out of the syringe interior volume  70 . As also shown in  FIG. 6C , the hub assembly  66  includes a tubular needle  78  sealingly secured to a hub distal section  80 , and a hub proximal section  82  which is capable of coupling to the syringe port  74 . The needle  78  of the hub assembly  66  shown in  FIG. 6E  is capable of penetrating the reservoir septum  44  of the first pump reservoir  36  but is mechanically incompatible with the second output port adapter  60  of the second pump reservoir  38 . 
     The fluid transfer system may also include a diabetic pen reservoir assembly  84  as shown in  FIGS. 6B, 6I, and 6J . The diabetic pen reservoir assembly  84  shown in  FIG. 6B  may include a diabetic pen reservoir body  86 , a pen interior volume  88  disposed within the diabetic pen reservoir body  86 , a second fluid  90  contained within the pen interior volume  88 , and a diabetic pen reservoir adapter  92 . The diabetic pen reservoir body  86  may include a pen port  94  which is in fluid communication with the pen interior volume  88 . The pen port  94  may be capable of coupling with the diabetic pen reservoir adapter  92 .  FIGS. 6B and 6I  show the diabetic pen reservoir adapter  92  and diabetic pen reservoir body  86  in a decoupled state, while  FIG. 6J  illustrates the diabetic pen reservoir adapter  92  as it is coupled to the diabetic pen reservoir body  86 . The diabetic pen reservoir adapter  92  is configured to be mechanically compatible with the second output port adapter  60  and mechanically incompatible with the input port  30  of the first pump reservoir  36 . For some embodiments, the second output port adapter  60  may be a male luer adapter and the diabetic pen reservoir adapter  92  may be a female luer adapter as shown in  FIGS. 6A and 6B , respectively. Additionally, the input port  30  may include a channel  96  (not shown) disposed within the multiple reservoir cartridge body  46 . In this case, the channel  96  transverse diameter may be too small to accept the diabetic pen reservoir adapter  92 , thus providing mechanical incompatibility and preventing the creation of a fluid communication junction between the diabetic pen reservoir assembly  84  and the first pump reservoir  36 . 
     Prior to being transferred into the first pump reservoir  36 , the first fluid  72  may be transferred from a vial reservoir  98  to the syringe reservoir  64  of the syringe hub assembly  62 .  FIG. 6D  shows the vial reservoir  98 . The vial reservoir  98  has a vial interior volume  100  which contains the first fluid  72 . A spigot port  102  disposed on the exterior of the vial reservoir  98  contains a vial septum  104  which seals the vial interior volume  100 .  FIG. 6E  shows the syringe hub assembly  62  of  FIG. 6C  and the vial reservoir  98  of  FIG. 6D .  FIG. 6F  depicts the needle  78  of the syringe hub assembly  62  penetrating the vial septum  104  disposed within the spigot port  102  of the vial reservoir  98  thereby creating a fluid communication junction between the vial reservoir  98  and the syringe reservoir  64 .  FIG. 6F  also depicts the plunger  76  being activated in order to transfer the first fluid  72  from the vial reservoir  98  to the syringe reservoir  64 . After the first fluid  72  has been transferred from the vial reservoir  98  to the syringe hub assembly  62 , it may then be transferred into the first pump reservoir  36 . Similarly, the second fluid  90  may be transferred from the diabetic pen reservoir assembly  84  to the second pump reservoir  38 . The fluid transfer system illustrated in  FIGS. 6A-6F  may be used to achieve these fluid transfers. 
     Some embodiments of a method for transferring fluids using the fluid transfer system are shown in  FIGS. 6H-6L . The method may include creating a first fluid communication junction between the first pump reservoir  36  and the syringe reservoir  64  by piercing the reservoir septum  44  of the first input port  30  with the needle  78  of the syringe hub assembly  62  as is shown in  FIG. 6G .  FIG. 6G  shows the needle  78  of the syringe hub assembly  62  inserted into the input port  30  of the multiple reservoir cartridge  28 .  FIG. 6H  is a sectional view of  FIG. 6G  showing the needle  78  having penetrated the reservoir septum  44 . The first fluid  72  is shown being transferred from the syringe reservoir  64  to the first pump reservoir  36  through the needle  30  which is in fluid communication with the first reservoir interior volume  42 . The first fluid  72  may be transferred by depressing the plunger  76  of the syringe reservoir  64 . The needle  78  may be configured such that it is mechanically incompatible with the second output port adapter  60  of the second output port  34  of the second pump reservoir  38  so as to mechanically prevent coupling between the syringe reservoir  64  and the second output port  34  and the creation of a fluid communication junction between the syringe reservoir  64  and the second output port  34 . 
     The method may also include creating a second fluid communication junction between the second pump reservoir  38  and the diabetic pen reservoir assembly  84  by coupling the second output port adapter  60  of the second output port  34  to the diabetic pen reservoir adapter  92 .  FIG. 6K  depicts the diabetic pen reservoir assembly  84  coupled to the second output port adapter  60 .  FIG. 6L  is a sectional view of  FIG. 6K  showing the second fluid  90  being transferred from the diabetic pen reservoir assembly  84  to the second reservoir interior volume  56  of the second pump reservoir  38 . The diabetic pen reservoir adapter  92  is configured such that it is mechanically incompatible with the input port  30  so as to prevent the creation of a fluid communication junction between the diabetic pen reservoir adapter  92  and the input port  30 . 
       FIGS. 6H-6L  depict the successful transfer of the first fluid  72  from the syringe reservoir  64  to the first pump reservoir  36 , and the transfer of the second fluid  90  from the diabetic pen reservoir assembly  84  to the second pump reservoir  38 . The method embodiment discussed may be performed by a patient or caregiver filling the multiple reservoir cartridge  28  of a pump device  10  with multiple pharmaceutical agents. In some cases it may be important that during the refilling procedure each agent is delivered to its appropriate respective receptacle due to the fact that the pump device  10  may deliver different agent doses from each receptacle. The existence of mechanical incompatibilities between the various interface ports in the method discussed may be used to prevent the user from transferring the wrong agent to the wrong receptacle reservoir. 
     In some cases the second output port adapter  60  of the fluid transfer system may be a male luer adapter and the diabetic pen reservoir adapter  92  may be a female luer adapter as shown in  FIGS. 6A and 6B , respectively. Additionally, the reservoir septum  44  may be disposed within a channel  96  of the multiple reservoir cartridge body  46 . In this case, if the user incorrectly attempts to transfer the second fluid  90  from the diabetic pen reservoir assembly  84  to the first pump reservoir  36 , this would necessitate the attempted creation of a fluid communication junction between the diabetic pen reservoir adapter  92  and the input port  30  of the multiple reservoir cartridge  28 .  FIG. 7A  illustrates how the mechanical incompatibility between the diabetic pen reservoir adapter  92  of the diabetic pen reservoir assembly  84  and the input port  30  (shown in the section view of  FIG. 6H ) prevents the creation of a fluid communication junction between the diabetic pen reservoir assembly  84  and the first pump reservoir  36 . 
     In order to establish a fluid communication junction between the diabetic pen reservoir assembly  84  and the first pump reservoir  36  the septum  44 , which seals the first reservoir interior volume  42 , needs to be penetrated or otherwise interrupted. As discussed above, this may be carries out by a sharpened tubular member such as the needle  78  which is configured to reach the septum  44  and has a sharpened end which is configured to penetrate the septum  44 . As shown in  FIG. 7A , the outer transverse diameter  108  of the diabetic pen reservoir adapter  92  is too large to insert into the interior transverse diameter  110  of the channel  96  of the input port  30 . In addition, the end of the diabetic pen reservoir adapter  92  is blunted and is not configured to penetrate the septum  44  even if the diabetic pen reservoir adapter  92  was small enough to pass through the channel  96  and reach the septum  44 . For some embodiments, the septum  44  and any other such septum embodiments discussed herein may be made from or may include a layer of resilient material that resists penetration by a blunt object. For some embodiments, the septum may be made from or may include a layer of any suitable elastomeric material, including rubber or suitable polymers. Thus, the creation of a viable fluid communication junction between the two embodiments is prevented by their mechanical incompatibility. 
     If a user attempts to transfer the first fluid from the syringe reservoir  64  to the second pump reservoir  38 , this would necessitate the attempted creation of a fluid communication junction between the needle  78  of the syringe hub assembly  62  and the second output port adapter  60  of the second output port  34 .  FIG. 7B  illustrates how the mechanical incompatibility between the needle  78  and the second output port adapter  60  mechanically prevents the creation of a fluid communication junction between the syringe reservoir  64  and the second pump reservoir  38 . As shown in  FIG. 7B , the outer transverse diameter  114  of the needle  78  is too small to form a fluid seal with the inner transverse diameter  116  of the second output port adapter  60 . Thus, the creation of a viable fluid communication junction between the components is prevented by their mechanical incompatibility. If the needle  78  were inserted into the second output port adapter  60 , any fluid dispensed from the needle  78  will leak from the gap between the outer transverse diameter  114  of the needle  78  and the inner transverse diameter  116  of the second output port adapter  60 . Thus, no pressure differential would be created between the syringe reservoir  64  and the second pump reservoir  38  and therefore no fluid would be transferred into the second pump reservoir  38 . 
     The components of an embodiment of fluid a transfer system are shown in  FIG. 8A-8C . The fluid transfer system may include a multiple reservoir cartridge  118  having a first pump reservoir  120  with a first pump reservoir body  122  and a first reservoir interior volume  124  disposed within the first pump reservoir body  122 . The first pump reservoir body  122  may be fabricated from a thin flexible material. The multiple reservoir cartridge may also have a multiple reservoir cartridge body  119 . The first pump reservoir  120  may include an input port  126  which has a reservoir septum  128  that seals the first reservoir interior volume  124 . The first pump reservoir  120  may also include a first output port  130  which is in fluid communication with the first reservoir interior volume  124 . The first output port  130  may include a first fluid line  132  (which may be, e.g., a flexible tube) which has an inner lumen and which connects the first reservoir interior volume to a first output port adapter  134 . 
     The multiple reservoir cartridge  118  of  FIG. 8A  may also include a second pump reservoir  136  which may have a second pump reservoir body  138  and a second reservoir interior volume  140  disposed within the second pump reservoir body  138 . The second pump reservoir body  138  as shown in  FIG. 8G  may be fabricated from a thin flexible material. The second pump reservoir  136  may also include a second output port  142  which may be in fluid communication with the second reservoir interior volume  140 . The second output port  142  may include a second fluid line  144  which may be a flexible tube which has an inner lumen and which connects the second reservoir interior volume  140  to a second output port adapter  146 . 
     The fluid transfer system may also include a syringe hub assembly  148  as shown in  FIG. 8D . The syringe hub assembly  148  includes a first syringe reservoir  150  and a hub assembly  152 , both of which are shown in  FIG. 8B . The first syringe reservoir  150  shown in  FIG. 8B  may include a first syringe body  154  and a first syringe interior volume  156  disposed within the first syringe body  154 . The first syringe body  154  may also include a first syringe port  158  which is capable of coupling with the hub assembly  152 . The first syringe reservoir  150  may also have a first plunger  160  which may form a slidable fluid tight seal against an inner surface of a bore of the interior volume and when manipulated can vary the volume of the first syringe interior volume  156  and thereby transfer a fluid into or out of the first syringe interior volume  156 . The hub assembly  152  includes a tubular needle  162  having an inner lumen, the tubular needle being sealingly secured to a hub distal section  164  and a hub proximal section  166  which is capable of coupling to the first syringe port  158 . The needle  162  of the hub assembly  152  shown in  FIG. 8B  is capable of penetrating the reservoir septum  128  of the first pump reservoir  120 , but is mechanically incompatible with the second output port adapter  146  of the second pump reservoir  136 .  FIG. 8D  shows the hub assembly  152  coupled to the first syringe reservoir  150  thus forming the syringe hub assembly  148 . The hub assembly  152  is coupled or releasably secured to the first syringe reservoir  150 . 
     A first vial reservoir  168  is shown in  FIG. 8B . The first vial reservoir  168  has a first vial interior volume  170 . A first spigot port  174  disposed on the exterior of the first vial reservoir contains a first vial septum  176  which seals the first vial interior volume  170 . The first vial interior volume  170  contains a first fluid  172 . 
       FIG. 8C  includes three more components of the fluid transfer system, a vial adapter  178 , a second vial reservoir  180 , and a second syringe reservoir  182 . The second vial reservoir  180  shown in  FIG. 8C  has a second vial interior volume  184  which contains a second fluid  186 . A second spigot port  188  disposed on the exterior of the second vial reservoir  180  contains a second vial septum  190  which seals the second vial interior volume  184 . The second syringe reservoir  182  may include a second syringe body  192  and a second syringe interior volume  194  disposed within the second syringe body  192 . The second syringe body  192  may also include a second syringe port  198  which is configured for coupling with the vial adapter  178 . The second syringe port  198  is contiguously formed into the second syringe body  192 . The second syringe reservoir  182  may also have a second plunger  200  which forms a fluid tight slidable seal against an inner bore of the interior volume and when manipulated can vary the volume of the second syringe interior volume  194  and thereby draw a fluid into or out of the second syringe interior volume  194 . 
     The vial adapter  178  shown in  FIG. 8C  has a proximal section  202  that is capable of coupling to the second vial reservoir  180  and forming a fluid communication junction with the second vial interior volume  184 . The vial adapter  178  also has a distal section  204  that is capable of coupling to the second syringe port  198 . The second syringe port  198  is configured such that it is capable of coupling to the second output port adapter  146  so as to form a fluid communication junction. The second syringe port  198  is also configured such that it is mechanically incompatible with the input port  126  so as to prevent a fluid communication junction between the two components. 
     Prior to being transferred into the first pump reservoir  120 , the first fluid  172  may be transferred from the first vial reservoir  168  to the first syringe reservoir  150  of the syringe hub assembly  148 .  FIG. 8E  shows the needle  162  of the syringe hub assembly  148  having penetrated the first vial septum  176  (shown in  FIG. 8B ) of the first vial reservoir  168 . Also shown in  FIG. 8E  is the first plunger  160  being drawn back, thereby transferring the first fluid  172  from the first vial reservoir  168  to the first syringe reservoir  148 . In a similar manner, before the second fluid  186  is transferred into the second pump reservoir  136 , the second fluid  186  may be transferred from the second vial reservoir  180  to the second syringe reservoir  182 .  FIG. 8H  depicts the coupling of the vial adapter  178  and the second vial reservoir  180 .  FIG. 8I  shows the second syringe port  198  of the second syringe reservoir  182  being coupled to the distal section  204  vial adapter  178 . After the vial adapter  178  has been coupled to the second syringe reservoir  182 , the second fluid  186  may be transferred from the second vial reservoir  180  to the second syringe reservoir  182 . 
     Some embodiments of a method for transferring fluids using the fluid transfer system are shown in  FIGS. 8F, 8G, 8J, and 8K . Some method embodiments may include creating a first fluid communication junction between the first pump reservoir  120  and the first syringe reservoir  150  by a piercing the reservoir septum  128  of the input port  126  of the first pump reservoir  120  with the needle  162  of the syringe hub assembly  148  as is illustrated in  FIG. 8F .  FIG. 8G  is a sectional view of  FIG. 8F  showing the needle  162  having penetrated the reservoir septum  128 .  FIG. 8G  also depicts the transferring of the first fluid  172  from the first syringe reservoir  150  to the first pump reservoir  120 . The needle  162  may be configured such that it is mechanically incompatible with the second output port adapter  146  of the second pump reservoir  136  so as to prevent the creation of a fluid communication junction between the first syringe reservoir  150  and the second output port  142 . 
     The method may also include creating a second fluid communication junction between the second pump reservoir  136  and the second syringe reservoir  182  by coupling the second output port adapter  134  of the second pump reservoir  136  to the second syringe port  198  of the second syringe reservoir  182  as is shown in  FIG. 8J .  FIG. 8K  is a sectional view of  FIG. 8J  showing the second fluid  186  being transferred from the second syringe reservoir  182  to the second pump reservoir  136 . The second syringe port  198  is configured such that it is mechanically incompatible with the input port  126  so as to prevent the creation of a fluid communication junction between the second syringe reservoir  182  and the first pump reservoir  120  if such a fluid communication junction is attempted by a user. 
     With regard to the method shown in  FIGS. 8E-8K , there may be mechanical compatibilities and mechanical incompatibilities configured into the various port interfaces which are used to transfer the fluids between the respective supply and receptacle reservoirs. The purpose of the mechanical incompatibilities is to prevent the user from transferring the first fluid  172  from the first syringe reservoir  150  to the second pump reservoir  136 , and/or from transferring the second fluid  186  from the second syringe reservoir  182  to the first pump reservoir  120 . These mechanical compatibilities and incompatibilities may be incorporated into structures such as second output port adapter  146  and the hub assembly  152 , as well as into the second syringe port  198  and the input port  126 . 
     In some cases, the second output port adapter  146  of the fluid transfer system may be configured as a female luer adapter as shown in  FIG. 8A  and the second syringe port  198  may be configured as a male luer adapter as shown in  FIG. 8C . Additionally, the reservoir septum  128  may be disposed within a channel  206  of the multiple reservoir cartridge body  119 . If a user incorrectly attempts to transfer the first fluid  172  from the first syringe reservoir  150  to the second pump reservoir  136 , this would necessitate the attempted creation of a fluid communication junction between the needle  162  of the hub assembly  152  and the second output port adapter  146  of the second output port  142 . 
       FIG. 9A  illustrates how the mechanical incompatibility between needle  162  and the second output port adapter  146  prevents the creation of a viable fluid communication junction between the first syringe reservoir  150  and the second pump reservoir  136 . As shown in  FIG. 9A , an exterior transverse diameter  208  of the needle  162  is too small to form a fluid seal with an interior transverse diameter  210  of the second output port adapter  146 . Thus, the creation of a viable fluid communication junction between the two embodiments is prevented by their mechanical incompatibility. In some cases, if the needle  162  is inserted into the second output port adapter  146 , any fluid dispensed from the needle  162  will leak from the gap between the exterior transverse diameter  208  of the needle  162  and the interior transverse diameter  210  of the second output port adapter  146 . 
     If the user attempts to transfer the second fluid  186  from the second syringe reservoir  182  to the first pump reservoir  120 , this would necessitate the attempted creation of a fluid communication junction between the second syringe port  198  of the second syringe reservoir  182  and the channel  206  of the input port  126 .  FIG. 9B  illustrates how the mechanical incompatibility between the second syringe port  198  and the input port  126  (shown in section view see  FIG. 8 ) prevents the creation of a fluid communication junction between the second syringe reservoir  182  and the first pump reservoir  120 . 
     In order to create a fluid communication junction between the second syringe reservoir  182  and the first pump reservoir  120 , the reservoir septum  128  which seals the first reservoir interior volume  124 , needs to be penetrated or otherwise interrupted. As discussed above, this may be carried out by a sharpened tubular member such as the needle  162  which is configured to reach the reservoir septum  128  and which has a sharpened distal end which is configured to penetrate the reservoir septum  128 . As shown in  FIG. 9B , the exterior transverse diameter  212  of the second syringe port  198  is too large to insert into the interior transverse diameter  214  of the channel  206 . In addition, the second syringe port  198  is blunted and is not configured to penetrate the reservoir septum  128  even if the if the second syringe port  198  was small enough to pass through the channel  206  and reach the reservoir septum  128 . The creation of a viable fluid communication junction between the two embodiments is thereby prevented by their mechanical incompatibility.

The multiple reservoir cartridge  216  may include a first pump reservoir  218  (as shown in  FIG. 14C ) having a first pump reservoir body  220  which may have a first reservoir interior volume  222  disposed within it.

FIG. 11B  shows the first hub assembly  302  separated from the first vial adapter  304  after the first engagement feature  324  has been disengaged. The first engagement feature  324  is shown in  FIG. 11A  as a break away rib; however, the first engagement feature  324  could also be configured as a threaded section on the first hub body  306  and a corresponding threaded section on the first vial adapter body  316  which would allow for the coupling of the two components.

FIGS. 12C and 12D  also show multiple dimensions including a second hub body diameter  384 , a second hub key feature diameter  386 , and a distance that the second needle extends from the second hub body  388 . The second circular array of bosses  378  which constitute the second hub key feature  338  are axially positioned such that they are substantially in axial alignment with the second circular array of slots  362  of the second port key feature  358  shown in  FIG. 10G . The axial alignment of the second circular array of bosses  378  and the second circular array of slots  362  are configured to allow for the insertion of the second hub assembly  326  into the second keyed port  244  with the bosses  378  sliding within respective slots  362 . If there is no corresponding slot  362  for each boss  378 , with a matched or paired circumferential spacing, a front edge of the impaired boss  378  will impinge upon the top surface of the keyed port  244  thereby creating mechanical incompatibility and preventing insertion of the hub assembly  326 . 
     The fluid transfer system embodiments discussed above may be used in order to safely transfer fluids from an appropriate supply reservoir to an appropriate receptacle reservoir.  FIG. 13A  shows the coupling the first vial adapter assembly  258  to the first vial reservoir  256  (both of  FIG. 10B ) by the insertion of the first spigot port  264  into the first distal cavity  318  such that the first needle  312  punctures the first vial septum  266  and the first vial adapter assembly  258  may be mechanically captured to the first vial reservoir  256  by the first hooked clip  322 .  FIG. 13A  also shows the coupling the second vial adapter assembly  268  to the second vial reservoir  270  (both of  FIG. 10C ) by the insertion of the second spigot port  276  into the second distal cavity  342  such that the second tubular needle  336  punctures the second vial septum  278  and the second vial adapter assembly  268  is mechanically captured to the second vial reservoir  270  by the second hooked clip  346  with an inner lumen of the tubular needle  336  in fluid communication with an interior volume of the second vial reservoir  270 . 
       FIG. 13B  depicts the coupling of the first syringe reservoir  282  of  FIG. 10D  to the first vial adapter assembly  258  by coupling the first syringe port  290  to the first hub body  306 .  FIG. 13B  also depicts the coupling of the second syringe reservoir  284  of  FIG. 10D  to the second vial adapter assembly  268  by coupling the second syringe port  298  to the second hub body  330 .  FIG. 13C  depicts the first fluid  262  being transferred from the first vial reservoir  256  to the first syringe reservoir  282  through the first vial adapter assembly  258 .  FIG. 13C  also shows the second fluid  274  being transferred from the second vial reservoir  270  to the second syringe reservoir  284  through the second vial adapter assembly  268 .  FIG. 13D  depicts the detachment of the first hub assembly  302  from the first vial adapter  304  after the disengagement of the first engagement feature  324 , thus creating the first syringe hub assembly  390 , with the first hub assembly  302  releasably secured to the first syringe reservoir  282 .  FIG. 13D  also depicts the detachment of the second hub assembly  326  from the second vial adapter  328  after the disengagement of the second engagement feature  348 , thus creating the second syringe hub assembly  392 , with the second hub assembly  326  releasably secured to the second syringe reservoir  284 . 
       FIGS. 14A-14C  show the multiple reservoir cartridge  216  of  FIG. 10A .  FIG. 14  A is a perspective view of the multiple reservoir cartridge  216 , while  FIG. 14B  is a sectional view of the multiple reservoir cartridge  216 .  FIG. 14C  is an enlarged detail view of  FIG. 14B ; the purpose of  FIG. 14C  is to illustrate the enlarged sectional views of the first keyed port  224  and the second keyed port  244 .  FIG. 15A  shows the first syringe hub assembly  390  and the first keyed port  224 .  FIG. 15B  is a transverse cross sectional view of the first hub body  306 , and  FIG. 15C  is a transverse cross sectional view of the first keyed port  224 . The first syringe hub assembly  390  may be inserted into the first keyed port  224  as shown in  FIG. 15D . The axial alignment and common circumferential spacing of the first circular array of bosses  366  and the first circular array of slots  354  allows for the insertion of the first hub assembly  302  into the first keyed port  224  with each boss  366  sliding within a respective slot  354 . Also a first channel diameter  396  may be configured to allow for the insertion of the first hub body  306  having first hub body diameter  372 . As shown in  FIG. 15D , the first tubular needle  312  has penetrated the first reservoir septum  230  thus creating a first fluid communication junction between the first syringe reservoir  282  and the first reservoir interior volume  222  through an inner lumen of the tubular needle  312 .  FIG. 15D  also shows the first fluid  262  being transferred from the first syringe reservoir  282  to the first reservoir interior volume  222 . 
       FIG. 16A  shows the second syringe hub assembly  392  and the second keyed port  244 .  FIG. 16B  is a transverse cross sectional view of the second hub body  330 , and  FIG. 16C  is a transverse cross sectional view of the second keyed port  244 . As shown in  FIG. 16D , the second syringe hub assembly  392  is mechanically compatible with the second keyed port  244  and may be inserted into the second keyed port  244 . The axial alignment and matching circumferential spacing of the second circular array of bosses  378  and the second circular array of slots  362  allows for the insertion of the second hub assembly  326  into the second keyed port  244 . Also, a second channel diameter  400  may be configured to allow for the insertion of the second hub body  330  having second hub body diameter  384 . As shown in  FIG. 16A , the second tubular needle  336  has penetrated the second reservoir septum  250  thus creating a second fluid communication junction between the second syringe reservoir  284  and the second reservoir interior volume  242  through the inner lumen of the second tubular needle  336 .  FIG. 1BD  also shows the second fluid  274  being transferred from the second syringe reservoir  284  to the second reservoir interior volume  242 . 
     A user of the fluid transfer system may attempt to transfer the first fluid  262  contained within the first syringe hub assembly  390  into the second pump reservoir  238   244 . Similarly, the user may attempt transfer the second fluid  274  contained within the second syringe hub assembly  392  into the first pump reservoir  218 . The user might also incorrectly attempt to couple the second vial adapter assembly  268  to the first vial reservoir  256 , or incorrectly attempt to couple the first vial adapter assembly  258  to the second vial reservoir  270 . With this in mind, the multiple fluid transfer interfaces used may be configured such that mechanical incompatibilities between interfaces which are not intended to be coupled prevent the creation of an incorrect fluid communication junction between two respective reservoirs. 
     In particular, a comparison of  FIG. 17B  and  FIG. 17C  shows that the first hub key feature embodiment  314  is mechanically incompatible with the second port key feature embodiment  358 . More specifically, the first hub key feature  314  includes  6  oblong bosses and the second port key feature  358  includes  4  oblong slots. Thus, as illustrated in  FIG. 17D , an attempt to insert the first syringe hub assembly  390  into the second keyed port  244  will result in the failure of the first hub body  306  to enter the second channel  248 . This is because the first hub key feature diameter  374  is larger than the second channel diameter  400 . As a result, as shown in  FIG. 17D  the first needle  312  does not penetrate the second reservoir septum  250  and therefore no fluid communication junction is created. 
       FIG. 18A  shows the second syringe hub assembly  392  and the first keyed port  224 . A comparison of  FIG. 18B and 18C  shows that the second hub key feature embodiment  338  is mechanically incompatible with the first port key feature embodiment  350 . The second hub key feature  338  comprises four oblong bosses and the second port key feature  350  includes six oblong slots. Thus, as illustrated in  FIG. 18D , an attempt to insert the second syringe hub assembly  392  into the first keyed port  224  will result in the failure of the second hub body  330  to enter the first channel  228 . This is because the second hub key feature diameter  372  is larger than the first channel diameter  396 . As a result, as shown in  FIG. 18D  the second needle  336  does not penetrate the first reservoir septum  230  and therefore no fluid communication junction is created. 
       FIG. 19A  shows the second vial adapter assembly  268  of  FIG. 10C  and the first vial reservoir  256  of  FIG. 10B . As shown in  FIG. 19A , the two embodiments are mechanically incompatible because the exterior transverse diameter  402  of the first spigot port  264  of the first vial reservoir  256  does not match the interior transverse diameter  404  of the second distal cavity  342  of the second vial adapter assembly  268 . Therefore, a mechanical coupling by the user between these two embodiments is impractical. The second hooked clip  346  would not engage the first spigot port  264 , therefore the second hub assembly  326  could not be separated from the second vial adapter  328  after the first vial reservoir  256  and second vial adapter assembly  268  have been coupled. Therefore, a mechanical coupling by the user between these two embodiments is impractical. 
     The first vial adapter assembly  258  of  FIG. 10B  and the second vial reservoir  270  of  FIG. 10C  are mechanically incompatible because the exterior transverse diameter  406  of the second spigot port  276  of the second vial reservoir  270  is too large to insert into the interior transverse diameter  408  of the first distal cavity  318  as shown in  FIG. 19B . The second spigot port  276  could not be inserted into the first distal cavity  318  so the first needle  312  cannot penetrate the second vial septum  190 . Therefore, a mechanical coupling by the user between these two embodiments is prohibited. 
       FIGS. 20A-20D  show the components of a fluid transfer system embodiment.  FIG. 20A  shows a multiple reservoir cartridge embodiment  410  which may include a first pump reservoir  412  (as shown in  FIG. 20M ) which has a first pump reservoir body  414  having a first reservoir interior volume  416  which is disposed within the first reservoir body  414 . The first pump reservoir body  414  may be fabricated from a thin flexible material. The first pump reservoir  412  may also include a first input port  418  which has a first channel  420  that is in fluid communication with the first reservoir interior volume  416 . The first input port  418  may also include a first septum  422  that is disposed within a multiple reservoir cartridge body  424  and which seals the first channel  420 . The first pump reservoir  412  may also include a first output port  426  which has a first fluid line  428  that is in fluid communication with the first reservoir interior volume  416 , and a first output port adapter  430  which is secured to and in fluid communication with the first fluid line  428 . 
     The multiple reservoir cartridge of  FIG. 20A  may also include second pump reservoir  432  (as shown in  FIG. 20M ) which may have a second pump reservoir body  434  having a second reservoir interior volume  436  which is disposed within the second pump reservoir body  434 . The second pump reservoir body  434  may be comprised of a thin flexible material. The second pump reservoir  432  may also include a second input port  438  which has a second channel  440  which is in fluid communication with the second reservoir interior volume  436 . A second septum  442  is disposed within the multiple reservoir cartridge body  424  and seals the second channel  440 , and a port key feature  444  is disposed on a perimeter  446  of the second channel  440 . The second pump reservoir  432  may also include a second output port  448  comprising a second fluid line  450  which is in fluid communication with the second reservoir interior volume  436 , and a second output port adapter  452  which is secured to and in fluid communication with the second fluid line  450 . 
       FIG. 20B  shows a diabetic pen reservoir  454  which may include a diabetic pen reservoir body  456  which has a pen interior volume disposed  458  within it. A first fluid  460  may be contained within the pen interior volume  458 . The diabetic pen reservoir  454  may also include a pen port  462  which is in fluid communication with the pen interior volume  458 .  FIG. 20B  also shows a bayonet needle adapter  464  which has a proximal section  466  that is capable of mating with the pen port  462  and a distal section  468  that is sealingly secured to a bayonet needle  470 . 
     A syringe reservoir  472  and a hub assembly  474  are shown in  FIG. 20C . The syringe reservoir  472  may include a syringe body  476  which may have a syringe interior volume  478  disposed within the syringe body  476 . The syringe reservoir  472  may also include a syringe port  480  and a plunger  482  which may be slidingly sealed to an inner bore of the syringe reservoir and when manipulated can vary the volume of the syringe interior volume  478  and thereby draw a fluid into or out of the syringe interior volume  478 . 
       FIG. 20C  also shows the hub assembly  474  which may include a hub body  484  having a proximal section  486  which is configured for coupling to the syringe port  480 , and a distal section  488  of the hub body  484  which is sealingly secured to a tubular needle  490  having an inner lumen extending along a length thereof. The needle  490  may be configured to pierce the second septum  442  in order to create a second fluid communication junction between the syringe interior volume  478  and the second reservoir interior volume  436 , but may also be configured to be mechanically incompatible with the second output port adapter  452  so as to prevent the creation of a fluid communication junction between the two components. The hub assembly  474  may also include a hub key feature  492  which is disposed on a perimeter  494  of the hub body  484 , and which is mechanically compatible with the second input port  438 , but is mechanically incompatible with the first input port  418 .  FIG. 20D  shows a vial reservoir  496  which may have a vial reservoir body  498 , and a vial interior volume  500  disposed within the vial reservoir body  498 . The vial reservoir  496  may have a spigot port  502 , and a vial septum  504  which may be disposed within the spigot port  502  and which seals the vial interior volume  500 . The vial interior volume  500  may contain a second fluid  506 . 
       FIGS. 20E-21B  illustrate a fluid transfer method for a fluid transfer system embodiment. The method may include inserting the tubular bayonet needle  470  into the first channel  420  such that it penetrates the first septum  422  as shown in  FIGS. 20F-20H . The method may also include creating a first fluid communication junction between the first pump reservoir  412  and the diabetic pen reservoir  454  by coupling the pen port  462  of the diabetic pen reservoir  454  to the bayonet needle adapter  464  as shown in  FIG. 20H . The bayonet needle adapter  464  is releasably secured to the diabetic pen reservoir  454 . The first fluid  460  may then be transferred from the diabetic pen reservoir  454  to the first pump reservoir  412  through the first fluid communication junction as is also shown in  FIG. 20H . 
       FIG. 20I  shows the vial reservoir  496  of  FIG. 20D .  FIG. 20I  also shows the hub assembly  474  and syringe reservoir  472 , both of  FIG. 20C , coupled together to form the syringe hub assembly  508 . The hub assembly  474  is releasably secured to the syringe reservoir  472 .  FIG. 20J  shows the tubular needle  490  of the syringe hub assembly  508  having penetrated the vial septum  504  (not shown) of the vial reservoir  496 , thereby forming a fluid communication junction between the vial interior volume  400  (not shown) and the syringe interior volume  478  (not shown) through an inner lumen of the tubular needle  490 .  FIG. 20J  also shows the plunger  482  of the syringe reservoir  472  being drawn back in order to transfer the second fluid  506  form the vial reservoir  496  to the syringe reservoir  472 . 
       FIGS. 20K-20M  show the multiple reservoir cartridge  410  of  FIG. 20A .  FIG. 20L  is a sectional view of  FIG. 20K .  FIG. 20M  is an enlarged view of  FIG. 20L  the purpose of which is to show detailed sectional views of the first input port  418  and the second input port  438 .  FIG. 20N  shows the syringe hub assembly  508  and the second input port  438 .  FIG. 20O  is a cross sectional view of the hub body  484 , and  FIG. 20P  is a cross sectional view of the second input port  438 .  FIG. 20O  shows the hub key feature  492  which consists of an array of oblong bosses  510  which run parallel to a hub central axis  512 .  FIG. 20O  also shows a hub body diameter  518  and hub key feature diameter  520 .  FIG. 20P  shows the port key feature  444  which consists of an array of oblong slots  514  which run parallel to a second channel central axis  516 .  FIG. 20P  also shows a second channel diameter  522  and a port key feature diameter  524 .  FIG. 20O  depicts the syringe hub assembly  508  inserted into the second input port  438 . The axial alignment and circumferential spacing of the array of oblong bosses  510  which comprise the hub key feature  492  and the matching circular array of oblong slots  514  which comprise the port key feature  444  allows for the insertion of the hub assembly  474  into the second input port  438 , with each boss  510  sliding within a respective slot  514 . Also, the second channel diameter  522  is configured to allow for the insertion of the hub body  484  having a hub body diameter  518 . As shown in  FIG. 20Q , the tubular needle  490  has penetrated the second septum  442  thus creating a second fluid communication junction between the syringe reservoir  472  and the second reservoir interior volume  436  through an inner lumen of the tubular needle  490 .  FIG. 20Q  also shows the second fluid  506  being transferred from the syringe reservoir  472  to the second reservoir interior volume  436 . 
     As exemplified in the method described in connection with, e.g.,  FIGS. 20A-20Q , there may be mechanical compatibilities and mechanical incompatibilities designed into the various port interfaces which are used to transfer the fluids between the respective reservoirs. The purpose of the mechanical incompatibilities is to prevent the user from transferring the first fluid  460  from the diabetic pen reservoir  454  to the second pump reservoir  432 , and/or from transferring the second fluid  506  from the syringe reservoir  472  to the first pump reservoir  412 . 
       FIGS. 21A and 21B  illustrate some mechanical incompatibility embodiments configured into the port interfaces for the embodiments described in  FIGS. 20A-20Q . In some cases the second output port adapter  452  of the fluid transfer system may be a female luer adapter as shown in  FIG. 20A , and the pen port  462  may be a male luer adapter as shown in  FIG. 20B . If a user attempts to transfer the first fluid  460  from the diabetic pen reservoir  454  into the second pump reservoir  432 , the exterior transverse diameter  526  of the pen port  462  is too large to insert into the second channel  440  which has a second channel diameter  552 . The ability to create a fluid communication junction between the diabetic pen reservoir  454  and the second input port  438  may be further hindered by the fact that the second reservoir septum  442  is located at a lower section of the second channel  440 . The second reservoir septum  442  must be penetrated in order to access the second reservoir interior volume  436 , and because the pen port  462  is too large to insert into the second channel  440  the second reservoir septum  442  cannot come into contact with the pen port  462  and therefore the second reservoir septum  442  will remain intact. A fluid communication junction between the diabetic pen reservoir  454  and the second pump reservoir  432  is therefore prevented by the mechanical incompatibility between the pen port  462  and the second channel  440 . 
     As shown in  FIG. 21C , the hub body  484  incorporates the hub key feature  492  which has a hub key feature diameter  520 . As shown in  FIG. 21D , the first channel  420  of the first input port  418  does not have a corresponding key feature embodiment. Therefore, the hub body  484  cannot be inserted into the first channel  420  of the first input port  418  as is shown in  FIG. 21B . This is because the hub key feature diameter  520  is larger than the first channel diameter  528 . This being the case, the tubular needle  490  of the hub assembly  474  cannot puncture the first reservoir septum  422  of the first input port  418  and therefore no fluid communication junction can be established between an interior volume of the syringe reservoir  472  and the first pump reservoir  412 .
