Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 62 / 740,490, filed October 3, 2018, which is incorporated by reference in its entirety under 35 U.S.C. § 119(e).

[0002] The disclosed embodiments relate to packaging for multiple containers. [Background technology]

[0003] Medicated fluids are often manufactured and packaged separately prior to use to preserve their chemical and physical stability. Medicated fluids may be combined at the time of administration, either by mixing the medicated fluids immediately prior to administration, or by administering the medicated fluids in parallel or sequentially.

[0004] Typically, these additional steps during administration are performed by a nurse or other medical personnel who may need to administer the medicated fluid to the patient according to a specific procedure. If additional medicated fluid is required, the method of administration may be performed by the nurse or other medical personnel multiple times for a given dosage.

[0005] Conventional packaging for medicated fluids can be bulky and cumbersome. When multiple medicated fluids are used in the administration process, separate containers must be procured and handled individually. Thus, administration methods and systems that combine medicated fluids with conventional packaging may lack efficient procedures and require many steps to connect and disconnect components and move fluids through various components in a specific manner. The inventors have recognized the need for a container unit that simplifies the administration of medicated fluids from multiple containers to a patient.

[0036] During a typical administration process, multiple syringes may be used to mix medicated fluids in a series of steps prior to injection into a patient. At each step, a nurse, doctor, or other medical professional takes care to ensure sterility as each fluid is withdrawn from its individual packaging and discharged into a mixing container. Even if the medicated fluids do not need to be pre-mixed prior to injection into a patient, each fluid is typically withdrawn from its individual container by a pump, syringe, or other suitable tool. If a larger dosage is required for a particular patient than that contained in a typical container, the process is typically repeated multiple times until the required dosage is reached. Thus, conventional administration methods performed by medical professionals typically use multiple individual containers of medicated fluids, which can be time-consuming and complicated.

[0037] In some treatments, multiple medicated fluids are administered to a patient in a mixture or sequentially in predetermined volumetric ratios. Containers of medicated fluids are typically supplied separately, and specific dosages can be measured out by a healthcare professional. Thus, significant time and effort is expended in procuring and preparing specific dosages for a patient. This time and effort can be further complicated for some patients who may require larger dosages than those supplied in standard containers, and healthcare professionals may be required to pool the medicated fluid across a range of differently sized containers. Upon completion of the fluid administration process, healthcare professionals may manage large volumes of containers and medicated fluid waste as a result of a single treatment.

[0038] In some cases, due to the frequency of treatments using some medicated fluids, self-administration is a preferred option for convenience and cost. A difficult procedure that is already time-consuming when performed by a medical professional can be difficult for patients to practice self-administration. For example, a patient may need to obtain and handle multiple containers of medicated fluid for a single administration process, which can be difficult and time-consuming. Therefore, reducing the time consumption and complexity of medicated fluid administration is desirable for self-administering patients because of improved convenience and reduced impact on daily life.

[0039] In light of the above, the inventors have recognized the advantages of a container unit that allows a patient to administer multiple medicated fluids contained separately in different containers. Compared to conventional administration processes, the container unit may enable the use of a simpler medicated fluid administration process having fewer steps. The container unit may also enable administration of a dosage with a predetermined ratio of medicated fluids so that medicated fluid preparation for a predetermined dosage is simplified. The container unit may include a first container, a second container, and a carrier configured to store the first container and the second container and hold them stationary relative to each other. The carrier may include features that allow the container unit to cooperate with a storage device, further simplifying administration of medicated fluids from one or more container units.

[0040] The inventors have also recognized the advantage of a container unit including a lip for attaching the container unit to an associated storage device. The lip may engage a latch on the associated storage device to attach the container unit to the storage device. Thus, a patient may quickly and reliably attach a container of medicated fluid to the storage device and administer multiple doses of medicated fluid for treatment.

[0041] In some embodiments, the container unit includes a first container, a second container, and a carrier configured to hold the first container and the second container stationary relative to one another. The carrier may include a lip protruding from at least a portion of the carrier's periphery. The lip may be configured to engage with a latch of an associated storage device when the container unit is connected to the storage device. After the lip engages with the latch, the lip may resist separation of the container unit from the storage device so that the container unit is secured to the storage device. In some embodiments, the lip may protrude from a portion of the periphery disposed around the first opening of the first container and / or the second opening of the second container. Such an arrangement may provide separation resistance near the interface between the first and second containers and the storage device.

[0042] The inventors have also recognized the advantages of a container unit including a carrier with a slot disposed between a first container and a second container. The slot may be configured to receive an insert from an associated storage device. Such an arrangement may prevent accidental removal of the container unit during use and may also facilitate secure and rapid connection of the container unit to the storage device to administer a medicated fluid for treatment.

[0043] In some embodiments, the container unit includes a first container, a second container, and a carrier configured to hold the first and second containers stationary relative to one another. The carrier may also include a slot disposed between the first and second containers. The slot may be configured to receive an insert of an associated storage device and may have a shape complementary to the shape of the insert. According to this embodiment, when the insert is received by the slot, the slot can resist forces applied to the container unit in one or more lateral directions. The slot may be used to guide the container unit as it is moved toward the storage device and connect the container unit to the storage device. By guiding the container unit, the slot can promote a secure fluid connection between the first and second containers and the storage device. In some embodiments, the slot may include an interior wall configured to engage a channel in the insert, thereby providing an additional guiding surface between the container unit and the associated storage device.

[0044] The inventors have also recognized the advantages of a container unit including a carrier with a first portion and a second portion, the first portion having an outer circumferential surface with a first shape and the second portion having an outer circumferential surface with a second shape, such an arrangement may facilitate attachment of the container unit in a proper orientation to an associated storage device and may facilitate secure and rapid connection of the container unit to the storage device.

[0045] In some embodiments, the container unit includes a first container, a second container, and a carrier configured to hold the first container and the second container stationary relative to one another. The carrier may include a first portion with a first shape and a second portion with a second, different shape. The first and second portions may be configured such that their combined shapes are complementary to the shape of a port on an associated storage device. Because the first and second shapes are different, the container unit may have a predetermined orientation in which the container unit is connectable to the storage device. In some embodiments, the first and second portions may be shaped to be complementary to the shape of the port of the storage device, so that the port can engage with the first and second portions and guide the container unit as it is connected to the storage device. In some embodiments, the first and second shapes may be elliptical, with the first shape having a first radius and the second shape having a different second radius.

[0046] The inventors have also recognized the advantages of a container unit including a first container, a second container, and a carrier with an extension. The extension may extend away from the first interior volume of the first container to at least the same height as the first stop of the first container. The extension may contact an associated storage device and resist insertion of the container unit into the storage device. Such an arrangement may facilitate reliable insertion depth of the spike of the storage device.

[0047] In some embodiments, the container unit includes a first container with a first stop, a second container with a second stop, and a carrier configured to hold the first and second containers stationary relative to one another. The carrier may have an extension extending away from the first container at least as high as the first stop. More specifically, according to these embodiments, the extension may extend away from the first interior volume of the first container at least as high as the end of the first stop facing away from the first interior volume. Thus, the offset between the extension and the end of the first stop may be greater than or equal to zero. The extension may be configured to contact a surface on an associated storage device and, when the extension contacts the storage device, to resist further insertion of the spike of the storage device into the first container. Thus, the extension may set a predetermined insertion (ie, puncture) depth for the spike of the reservoir device and facilitate an effective seal and fluid connection between the first and second containers and the reservoir device.

[0048] In some embodiments, the appropriate offset between the extension of the container unit and the first stop of the first container held by the carrier (i.e., the distance the extension extends beyond the end of the first stop in a direction away from the first container) may be greater than or equal to about 0 mm, 0.25 mm, 0.75 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or any other suitable offset. Correspondingly, the offset between the extension of the carrier and the first stop may be less than or equal to about 2.75 mm, 2.25 mm, 1.75 mm, 1.25 mm, 0.75 mm, 0.5 mm, 0.1 mm, or any other suitable offset. Combinations of the above ranges are also contemplated, including, for example, offsets of 1 mm to 2 mm, 0 mm to 2 mm, 0.5 mm to 1.5 mm, and 1.5 mm to 2.5 mm or equal thereto. Of course, any suitable offset may be used, including distances both greater than and less than those noted above, and the present disclosure is not so limited.

[0049] In some embodiments, the container unit includes a first container, a second container, a carrier, and a lid. The first and second containers may each include an interior volume, a stop, and a seal. The stop may be disposed within the container opening, and the seal may cover the stop and provide protection for the stop prior to use of the container unit. The first and second containers may have different interior volumes and may hold different medicinal fluids for administration to a patient. In some embodiments, the volumes of the first and second containers may be related by a predetermined ratio. The carrier may be configured to hold the first and second containers stationary relative to each other. The carrier may include a first section and a second section that may be connected to the peripheries of the first and second containers to secure the first and second containers within the carrier. The first and second sections may include a section latch and a section latch receptacle configured to secure the first section to the second section when they are mated. The first and second sections may also include one or more alignment members to guide and facilitate proper alignment of the section latch and section latch receptacle. In some embodiments, the carrier may include a base disposed over and extending between the lowermost portions of the first and second containers. The lid may be disposed over an upper portion of the carrier where the stops and seals of the first and second containers are disposed so that the lid can protect the seals and stops of the first and second containers. In some embodiments, the lid may be disposed at least partially around the seals of the first and second containers so that removal of the lid can also remove the seals and expose the stops. The lid may include a tab configured to facilitate lift-off and removal of the lid and, in some embodiments, the seals.

[0050] In some embodiments, the medicated fluid storage device includes a housing with multiple ports and at least one fluid distribution system. The multiple ports may include spikes or other fluid connectors suitable for fluidly connecting one or more containers of medicated fluid to at least one fluid distribution system. The ports may include multiple spikes, which may be used to fluidly connect multiple containers packaged together in a container unit. The fluid distribution system may include a fluid interface air filter, tubing, and fluid connectors used to draw fluid from one or more containers once they are fluidly connected to the fluid distribution system. The ports may be configured to receive one or more container units in an inverted position so that gravity can be used to feed the medicated fluid from the containers to the fluid connectors. The fluid distribution system may supply a single medicated fluid from multiple containers connected to different ports, or may supply a mixture of different medicated fluids connected to different ports. The air filter may allow air into the fluid distribution system to be replaced by any volume of fluid drawn from the fluid connector. The fluid connector may be configured to connect to any patient device that can be used to administer fluid to a patient, such as an infusion pump or syringe.

[0051] In some embodiments, a method for administering medicated fluid using a medicated reservoir device includes connecting one or more container units to one or more ports, coupling a patient device to a fluid connector of a fluid distribution system, and drawing medicated fluid from two or more containers disposed within the container units. The ports of the medicated reservoir device may include one or more spike assemblies, each including a hollow spike and a spike sheath covering the spike. Once the cover is removed to expose the spike assemblies, connecting the containers to the spikes may include pushing the containers of the container units onto the spikes, causing the spike sheaths and containers to be punctured by the spikes, allowing fluid communication between the spikes and the interior volumes of the containers. Once the container units are connected, medicated fluid from the containers may flow through the spikes and associated tubing to a fluid connector that may be used to connect the fluid distribution system to an infusion pump, syringe, or other device for administration of the fluid into the patient. When more than one container unit is connected to a fluid distribution system, the total volume of fluid in each of the connected containers of the container units may be combined and delivered as a single volume at the fluid connector. When multiple containers are used, the spike sheath may form a seal against the spike prior to the spike puncturing the container, allowing any medicated fluid to be contained within the spike sheath and spike, which may allow the containers to be punctured sequentially or non-sequentially without any loss of medicated fluid. In some embodiments, multiple fluid distribution systems may be used in a medicated reservoir device to deliver different medicated fluids or provide a mixture of different medicated fluids.

[0052] In some embodiments, a method for manufacturing a container unit includes obtaining a first container, a second container, and a carrier including a first section and a second section. The method further includes placing the first container and the second container in first and second recesses of the first section, respectively, configured to receive the first and second containers. Once the first and second containers are placed in the first section, the second section can be placed over the first and second containers such that the first and second containers are held stationary relative to each other within the carrier. In some embodiments, the method can include aligning the first and second sections such that a section latch on one of the sections aligns with a section latch receptacle on the other section. These section latches and receptacles can be used to secure the first and second sections together around the first and second containers. In some embodiments, the first and second sections may be secured together with a mechanical depression force, which applies a force to the first and second sections to engage corresponding section latches and receptacles. The method of manufacture may be performed manually, semi-autonomously, or fully autonomously, and the present disclosure is not so limited.

[0053] In some embodiments, the suitable volume of the container of the container unit may be greater than or equal to about 1.25 mL, 2.5 mL, 5 mL, 10 mL, 25 mL, 50 mL, 100 mL, 200 mL, 300 mL, or any other suitable volume. Correspondingly, the volume of the container may be less than or equal to about 350 mL, 250 mL, 150 mL, 75 mL, 35 mL, 15 mL, 7.5 mL, 3 mL, 1.5 mL, or any other suitable volume. Combinations of the above ranges are also contemplated, including, for example, volumes between 1.25 mL and 15 mL, between 25 mL and 300 mL, between 100 mL and 350 mL, and between 1.25 mL and 50 mL or equivalent. Of course, any suitable volume may be used, including volumes both greater than and less than those recited above, but the present disclosure is not so limited.

[0054] In some embodiments, the container unit may be used in conjunction with a storage device to dispense medicated fluid from multiple containers within the container unit. An example of a storage device that may be used in conjunction with the container units described herein is described in U.S. Patent and Trademark Office Application No. 15 / 186,061, entitled "POOLING DEVICE FOR SINGLE OR MULTIPLE MEDICAL CONTAINERS," filed June 17, 2016, and incorporated herein by reference. In the event that the present specification and any document incorporated by reference include conflicting and / or inconsistent disclosure, the present specification shall control. In the event that two or more documents incorporated by reference include conflicting and / or inconsistent disclosure with respect to each other, the document having the later effective date shall control.

[0055] Although the embodiments described herein may relate to a container unit in combination with a reservoir device, any suitable tool or mechanism may be employed to dispense medicated fluid from the container unit. For example, a pump, syringe, or other suitable tool may also be used to withdraw and dispense medicated fluid from the container unit. According to these examples, the pump, syringe, or other tool may be directly coupled to one or more reservoirs of the container unit. In such an arrangement, the container unit may provide simplified packaging and access to multiple medicated fluids. Of course, the container unit may be used in combination with any suitable dispensing device, tool, or system, and the present disclosure is not so limited.

[0056] FIG. 1 depicts one embodiment of a container unit 100 including a first container 110A, a second container 110B, and a carrier formed from a first section 120A and a second section 120B. The carrier includes a slot 122, a bottom 124, a rim 126, recesses 128A, 128B, and a handle 130. The slot 122 is formed in the carrier and is configured to receive an insert of a medicated storage device having a shape complementary to the container unit, leading into a port of the storage device. The bottom 124 covers and extends through the bottom portions of each of the containers (see, e.g., FIG. 3 ). Thus, the bottoms create a substantially continuous surface on the bottom portions of the first and second containers, which may be used by a patient or medical professional to apply force to the container unit. The rim 126 protrudes outward from the periphery of the container unit. More specifically, according to the embodiment of FIG. 1, a rim protrudes from the top portion of the carrier, positioned near the openings of the first and second containers. Recesses 128A, 128B are configured to receive and retain the first and second containers within the carrier. The recesses may comprise a high-friction material, a compressible material, or other suitable arrangement for holding the first container stationary relative to the second container. In some embodiments, the first and second containers may be rotatable about their longitudinal axes, but may also be translationally held stationary by the carrier. The handle 130 and / or the bottom 124 (including the hollow portion between the first and second containers) can be easily used by a patient or other medical professional to grasp the carrier and manipulate the container unit.

[0057] As shown in the embodiment of FIG. 1 , the container unit 100 also includes a lid 150 with a tab 152. The lid is removably attached to the carrier formed by sections 120A, 120B of the container unit and rests on edge 126. The tab may be used to lift and remove the lid from the carrier, revealing the first container and second container openings. In some embodiments, the first container and second container may each include a stop and a seal (see, e.g., FIG. 3 ) that covers and protects the stop. In this embodiment, one or more container engagement fingers (not shown) may engage the seal on the container and may be configured to remove the seal when the lid is removed from the carrier. That is, by lifting tab 152, the seal on each of containers 110A, 110B may be broken and / or removed, revealing the container and its associated stop. The lid 150 may provide protection for the first and second containers until the container unit is ready for use.

[0058] FIG. 2 is a front view of the container unit 100 of FIG. 1. As shown in FIG. 2, the slot includes a side wall 122A, a curved wall 122B, and an inner wall 122C. Thus, the slot, along with the inner and side walls, defines at least three sides of a rectangular pillar. The curved wall defines a horizontal cylindrical section positioned on the proximal end of the slot. According to the embodiment shown in FIG. 2, the associated storage device may have an insert with a shape complementary to that of the slot. That is, the insert may include at least three walls of a rectangular pillar and a horizontal cylindrical section positioned on the distal end of the insert. Thus, the slot may guide the container unit as it is connected to the associated storage device, facilitating effective alignment and orientation of the container unit.

[0059] As shown in FIG. 2 , the handles 130 provide adequate space for a patient or medical professional to grip the container unit. For example, the container unit may be gripped around the bottom 124, around the first container 110A, or around the second container 110B. Thus, the handles may allow the container unit to be more easily handled when inserted into a storage device, otherwise coupled to another medical device, or moved around. Stability provided by the handles may be desirable as the containers may each be punctured to gain access to the medicated fluid disposed therein. For example, the handles may be gripped while removing the lid 150, turning the container unit over, inserting the container unit into the storage device, and puncturing both containers. As shown in FIG. 2 , the handles are cylindrical in shape, but any suitable shape that simplifies handling of the container unit may be employed.

[0060] FIG. 3 depicts an exploded view of an embodiment of a first container 110A and a second container 110B. The first container includes a first opening 112A to a first interior volume, the first opening being defined by a first flat surface, a container rim 114A, a stop 116A, a seal 118A, a bottom portion 111A, and a reduced diameter portion 115A. The stop is configured to be inserted into the opening and fluidly seal the first interior volume and rests on the container rim. The seal is configured to fit over both the stop and the extension so that the stop remains seated within the opening. Thus, the seal 118A is a protective element that can be left in place until the container is ready to be coupled to another medical device. In some embodiments, the stop 116A may be made of a material suitable for being punctured by a needle or spike, such as natural or synthetic rubber. Of course, the stop may be made of any suitable material for sealing the opening 112A, and the disclosure is not so limited. In some embodiments, the stop may not rest on the container rim 114A, but may be located completely within the opening 112A, and the disclosure is not so limited.

[0061] As shown in FIG. 3, the second container 110B includes components similar to those of the first container 110A. The second container includes a second opening 112B defined by a second flat surface, a second container rim 114B, a second stop 116B, a second seal 118B, a second bottom portion 111B, and a second reduced diameter portion 115B. The second stop, like that of the first container, is configured to be inserted into the second opening and seal the second interior volume. The second seal is positioned around the stop and container rim prior to the container being ready for use during the administration process, securing the stop within the second opening. As shown in FIG. 3, the first stop 116A and the second stop 116B may include variations depending on the size of the container and the type of medicated fluid to be placed therein. Similarly, the seal may vary depending on the shape of the container edge of the container so that the stop can be securely held within the opening. For example, the second stop may include a ridge to facilitate sealing and marking. The stop and seal may use any suitable configuration that effectively seals and protects the opening of the container, and the present disclosure is not so limited.

[0062] According to the embodiment shown in FIG. 3, the dispensing process of medicated fluid from first container 110A and second container 110B may include manipulating seals 118A, 118B and / or stops 116A, 116B. In some embodiments, the dispensing process may include removing first seal 118A and second seal 118B from the first container and second container, respectively. Once the seals are removed, the stops may be exposed such that they can be punctured by a needle or spike of an associated medical device. Of course, the stops may also be removed to couple the container to an associated medical device or to dispense the contents of the container, and the present disclosure is not so limited.

[0063] FIG. 4 depicts an exploded view of an embodiment of a carrier including a first section 120A and a second section 120B. As shown in FIG. 4 and discussed above, the first section 120A includes a slot 122, a bottom 124, a rim 126, a first recess 128A, a second recess 128B, and a handle 130. The slot 122 includes a side wall 122A, a curved wall 122B, and an inner wall 122C. The bottom 124 extends between the first and second recesses, which are configured to hold first and second containers, respectively. The rim 126 protrudes outward from the periphery of the upper portion of the first section.

[0064] According to the embodiment of FIG. 4, the first section 120A includes two container neck holders 132A, 132B, a section latch 134, and an alignment member 138. The container neck holders 132A, 132B can cooperate with the first recess 128A and the second recess 128B to securely hold the first and second containers within the carrier. The container neck holders can engage the necks of the first and second containers (e.g., see FIG. 3) to prevent longitudinal movement of the first and second containers. The section latch 134 projects outward from the first section and is configured to engage a section latch receptacle 136 on the second section 120B to secure the first section to the second section. Alignment members 138 on the first section may similarly engage alignment members on the second section to properly orient the first section relative to the second section and align the section latch with the section latch receptacle.

[0065] As shown in FIG. 4 , the second section 120B of the carrier includes components complementary to those of the first section 120A. The second section includes a slot 122, a bottom 124, a rim 126, a first recess 128A, a second recess 128B, and a handle 130. According to the embodiment of FIG. 4 , the first and second sections can be combined to create a completed component. That is, the slot, bottom, upper rim, first recess, second recess, and handle of one of the first and second sections can be part of a larger whole that is completed when the first section is secured to the second section. For example, the slot 122 of the first section can be combined with a slot of the second section to create a single slot that is, in effect, disposed between the first container and the second container. Similarly, the edge 126 of the second section can mate with the edge 126 of the first section to create a substantially continuous upper edge that protrudes from the outer periphery of the carrier. As shown in FIG. 4 , the second section also includes container neck holders 132A, 132B, a section latch receptacle 136, and a matching member 138, which cooperate with corresponding components of the first section. The container neck holders 132A, 132B of the second section can mate with the container neck holders 132A, 132B of the first section to form an enclosed space for holding the container neck. The section latch receptacle 136 is configured to receive the section latch 134 so that the first and second sections can be mated and secured to one another. Similarly, the alignment members 138 of the second segment are configured to receive the alignment members of the first segment and guide and properly orient the first segment relative to the second segment. Note that in some embodiments, the alignment members 138 can be reversed such that the alignment members of the first segment are configured to receive the alignment members of the second segment.

[0066] According to the embodiment of FIG. 4 , the first section 120A and the second section 120B may be configured as equal parts of the carrier. That is, the carrier is divided into the first section 120A and the second section 120B approximately along a central longitudinal plane. Such an arrangement may allow first and second containers to be easily enclosed by the carrier by placing the containers in the recesses 128A, 128B of the first section and securing the second section around the containers. In some embodiments, the first and second sections may be asymmetric or otherwise divided into unequal parts. For example, the first section may form more than half of the carrier, and the second section may simply function as a cap to secure the containers in place. In some embodiments, the first and second sections may be divided along a transverse plane. For example, the carrier may be divided into a bottom and a top section such that the container may be placed in a first, bottom section and secured in place by a second section on top. Of course, any suitable arrangement for the first and second sections may be employed, and the present disclosure is not so limited.

[0067] FIG. 5 depicts an exploded alternative view of the receptacle unit of FIG. 4 , showing the inside of the first section 120A, including the section latch 134. As described above, the section latch 134 is configured to secure the first and second sections 120B together when the section latch is received by the section latch receptacle 136. According to the embodiment shown in FIG. 5 , the corresponding section latch and section latch receptacle pair each include a catch configured to secure in a recess or hole. As shown in FIG. 5 , the peripheral section latch includes a catch (e.g., a barbed end or distal protrusion) configured to be received by a recess or hole in the section latch receptacle (e.g., see FIG. 6 ). In contrast, the center section latch includes a hole configured to receive a triangular catch disposed in the corresponding center section latch receptacle (e.g., see FIG. 4 ). 5, the rectangular center segment latches may be larger than the peripheral latches and may provide the majority of the securing force for the first and second segments when inserted into corresponding segment latch receptacles. Of course, the segment latches and segment latch receptacles may have any suitable arrangement with any suitable securing force distribution, and the present disclosure is not so limited.

[0068] FIG. 6 depicts one embodiment of a segment latch 134 and segment latch receptacle 136 for a carrier. As shown in FIG. 6, the carrier is split into a first segment 120A and a second segment 120B. The segment latch 134 and segment latch receptacle 136 are disposed on the bottom 124 of the carrier. The segment latch 134 may include a barbed end or other distal protrusion that can be received by the segment latch receptacle 136. The segment latch 134 may be resiliently deflectable such that the barbed end deflects out of the way as the segment latch is inserted into the segment latch receptacle. Once the segment latch is fully inserted into the segment latch receptacle, a window in the segment latch receptacle may receive the barbed end so that the segment latch can return toward the rest position. Once the segment latch is returned toward the rest position, the barbed end can resist forces that can separate the first segment from the second segment. In the embodiment shown on FIG. 6, the segment latch 134 may be depressed to release the segment latch from the segment latch receptacle 136 .

[0069] Although latches are shown and described in the embodiment of FIG. 6 , any suitable fasteners may be used to secure a first segment of the carrier to a second segment of the carrier. For example, screws, bolts, tacks, rivets, adhesive, or any other suitable fasteners may be used to secure the first segment to the second segment. The fasteners may be removable or substantially permanent. In some embodiments, different fasteners may be used in combination to secure the first segment to the second segment. For example, combinations may include, but are not limited to, a segment latch and adhesive, a segment latch and a screw, and a screw and adhesive. The fasteners may be placed in virtually any suitable location between the first and second segments to secure the first segment to the second segment.

[0070] FIG. 7 depicts a partially exploded view of the container unit 100 of FIG. 1, including the lid 150. As shown in FIG. 7, the lid 150 is removed from the carrier formed by sections 120A and 120B. As described above, the lid includes a tab 152, which facilitates lid removal. The container unit includes a first container 110A and a second container 110B disposed within the carrier, with the openings of the first and second containers disposed adjacent to an interface portion 144 of the carrier. The lid may partially fit inside the carrier to removably attach the lid to the carrier. The first container includes a first seal 118A, and the second container includes a second seal 118B. According to the embodiment of FIG. 7, the lid engages with the first seal and the second seal. As the lid is removed from the carrier, the seals may also be removed with the lid. According to the embodiment of FIG. 7, the seals may be more easily removed by lifting the tab. That is, without wishing to be bound by theory, the lid may function as a second type of lever, with the seal acting as the load and the carrier acting as the fulcrum.

[0071] According to the embodiment of FIGS. 7-9, the lid 150 may engage the seals 118A, 118B to simplify its removal during the administration process. For example, container engagement fingers 154 (see FIG. 8) may be configured to engage the downwardly facing edge of the upper seal so that the lid can be used to apply an upward force to the seal. Alternatively, adhesive or other suitable fasteners may be used to physically couple the lid and seal so that they remain substantially stationary relative to one another. As shown in the embodiment of FIG. 7, the lid includes a tab 152, which may be used to apply force to the seal. In some embodiments, the tab may include a hinged portion that can extend to provide additional leverage to the patient or healthcare professional removing the lid. According to the embodiment shown in FIGS. 7 and 9, the lid also includes a rotation inhibitor 156, which prevents the lid from being rotated about either of the seals 118A, 118B prior to complete removal of the lid. That is, the rotation inhibitor contacts the inner wall 158 of the carrier interface portion 144 and prevents rotation away from the container 110A, 110B about an axis extending from either of the seals. Such an arrangement may allow the lid to be rotated about its longitudinal axis and / or lifted away from the container in a direction along an axis extending from either of the seals, such as when the lid is lifted by the tab 152. Of course, any suitable arrangement of the lid and seal may be employed, and the disclosure is not so limited.

[0072] FIG. 8 depicts a cross-sectional view of the container unit 100 of FIG. 1 taken along line 8-8 of FIG. 2. As shown in FIG. 8, the container unit includes a container 110 disposed within a carrier formed by sections 120A and 120B. The container 110 includes an opening 112 to an interior volume within which a stop 116 is disposed. A seal 118 is wrapped around the stop and a container rim 114 of the container. A bottom portion 111 of the container is retained within the carrier within the recess 128 and the container neck holder 132. A lid 150 is disposed partially inside the carrier and includes a tab 152 and a plurality of container engagement fingers 154. The container engagement fingers 154 are disposed around and in contact with the seal 118. Thus, when the lid is removed (e.g., by lifting the tab), the container engagement fingers 154 will engage the downwardly facing edge of the seal 119 and apply a removal force to the seal. Thus, the seal 118 will be completely removed along with the lid 150.

[0073] In the embodiment of FIG. 8 , the container engagement fingers 154 may be angled toward the seal 118 and may be made of a flexible material. Thus, when the lid 150 is placed over the container 110 and carrier 120, the container engagement fingers may deflect (i.e., flex) out of the path of the seal so that the lid can be removably secured to the carrier. Once the lid is secured, the container engagement fingers may be biased toward the seal so that the container engagement fingers remain in contact with the seal. Thus, when the lid is lifted, the container engagement fingers do not flex out of the path of the seal, but rather engage the seal and apply a removal force. Such an arrangement may provide simplified manufacturing and ensure that the seal is removed when the lid is removed with a simple motion. The lid may be made of any suitable flexible material, including, but not limited to, plastic and metal. Of course, the lid may employ any suitable arrangement that covers and protects the opening of the container, and the present disclosure is not so limited.

[0074] FIG. 9 depicts a bottom view of the lid 150 of the container unit of FIG. 7. As described above, the lid includes tabs 152 configured to allow an operator to apply force to a seal engaged by the lid. In particular, container engagement fingers 154 engage the seal of the container and remove the seal when the lid is removed. In some cases, the lid may be made of a flexible material so that one side of the lid can be removed (with corresponding removal of the container seal on the same side) without removing the seal engaged by the opposite side of the lid. For example, a first portion of the lid can be pulled up along axis 155A to remove the first seal and then rotated about axis 155B, while a second portion of the lid remains engaged with the second seal, which remains within opening 112B. As shown in FIG. 9, the lid includes one or more rotation inhibitors 156. The rotation inhibitor is configured to engage one or more components of the carrier (e.g., see interior wall 158 in FIG. 7 ) and prevent rotation of the lid about either axis 155A or 155B when the corresponding portion of the lid is lifted and spaced away from the carrier, preventing an operator from accessing one container while maintaining the integrity of the seal on the other container. More specifically, the rotation inhibitor prevents lifting one side of the lid, removing the seal on the first container, and rotating the lid about the seal on the second container to expose the first container, while maintaining the seal on the second container. According to the embodiment shown in FIG. 9 , the rotation inhibitor prevents rotation of the lid about either axis 155A or 155B without preventing translation of the lid along that axis. 9 does not prevent translation of the lid in the removal direction away from the carrier (i.e., in the direction of axes 155A, 155B toward the far side of the page) or rotation of the lid about its longitudinal axis 153 or any axis parallel to longitudinal axis 153. Thus, an operator can use tab 152 to remove the lid from the carrier by translating the lid and / or rotating the lid about its longitudinal axis or any axis parallel to longitudinal axis 153, removing both seals from the rotation inhibitor without interference.

[0075] As shown in FIG. 9 , rotation inhibitor 156 is configured as two walls shaped to complement and fit tightly with the shape of the inner walls (see, for example, inner wall 158 in FIG. 7 ) so that rotation about axes 155A and 155B is prevented. When the lid is rotated about either axis 155A or 155B, at least one of the rotation inhibitors contacts a portion of the carrier and prevents further rotation. That is, the rotation arc traced by the rotation inhibitor about either axis 155A or 155B overlaps with a portion of the carrier such that the rotation inhibitor interferes with the carrier when the lid is rotated about either axis. However, when moved in other directions (e.g., rotation about longitudinal axis 153, an axis parallel to axis 153, or translation along axes 155A and 155B), the rotation arc and / or translation path of the rotation inhibitor may not overlap with the carrier in those directions so that no interference occurs and the lid is free to move in those directions. In some cases, a tight fit between the rotation inhibitor and the carrier may improve prevention of rotation about axis 155A or 155B by reducing rotational clearance in those directions. Of course, while the rotation inhibitor shown in FIG. 9 is configured as two walls that fit tightly against the inner wall of the carrier, the rotation inhibitor may be configured as any suitable structure that impedes lid rotation. In some embodiments, the rotation inhibitor may be positioned between two container-engaging fingers proximate the geometric center of the lid. Such an arrangement may ensure that rotation is suitably prevented when either side of the lid is lifted, by ensuring that the rotational arc of the rotation inhibitor is greater than the rotational clearance of the carrier in the direction of rotation about axis 155A or 155B. In some embodiments, the rotation inhibitor may be positioned outside the inner wall of the container and configured to engage the outer wall of the carrier and prevent lid rotation.

[0076] FIG. 10 depicts a bottom view of the receptacle unit 100 of FIG. 1. As shown in FIG. 10, the receptacle unit includes a carrier formed from a first section 120A and a second section 120B. The carrier includes a bottom 124, which is substantially continuous and extends in a plane. According to the embodiment of FIG. 10, the bottom covers the lowermost portion of the receptacle held within the carrier (see, e.g., FIGS. 3 and 8). The bottom also spans any lateral (i.e., transverse) gaps or spaces between the lowermost surfaces of the receptacle within the carrier. Thus, the bottom can provide a surface against which a force can be applied. According to the embodiment of FIG. 10, the receptacle unit can be configured to connect with a storage device along an upper portion of the receptacle unit. In some embodiments, force can be used to engage one or more latches of the receptacle unit and the storage device and puncture the receptacle of the receptacle unit with one or more spike assemblies. Therefore, it may be desirable to provide a smooth surface on the receptacle unit, which can be used to apply a uniform force to the carrier and each of the receptacles disposed therein. In some embodiments, the bottom surface may at least partially cover the bottom portion of each of the receptacles disposed within the carrier. According to this embodiment, the portion of the carrier that can be used to apply a force to each of the bottom portions of the receptacles may be suitable for connecting the receptacle unit to a storage device. In some embodiments, the bottom 124 of the receptacle unit may be substantially flat. Such an arrangement may be desirable if the receptacle unit is to be set upright on a flat surface. For example, a flat bottom may be desirable for the receptacle unit to be set upright on a tabletop. A flat arrangement of the bottom may also facilitate the application of force to the receptacle unit. Of course, the bottom of the receptacle unit may adopt any suitable arrangement with an appropriate shape, and the present disclosure is not so limited.

[0077] FIG. 11 depicts a top view of the container unit 100 of FIG. 1 with the lid 150 removed, revealing the interface portion 144. As shown in FIG. 11, seals 118A, 118B are positioned across the stops and openings of the first and second containers. The containers are positioned within a carrier formed from a first section 120A and a second section 120B and have an interface portion 144. The interface portion includes a slot 122 positioned between the first and second containers. As described above, the slot includes a side wall 122A, a curved wall 122B, and an inner wall 122C. The inner wall 122C divides the slot into two portions, each with an equally sized side wall and a curved wall. As shown in FIG. 11, each portion of the slot forms at least three walls of a rectangular pillar. As described above, a storage device or other medical device may have an insert with a shape complementary to that of the slot. The insert may include protrusions separated by channels configured to receive the inner walls 122C of the slot, so that the slot can guide and orient the container unit into the correct position as the container unit is coupled to a storage device or other medical device.

[0078] As shown in FIG. 11 , the carrier interface portion 144 formed by sections 120A and 120B includes a first outer circumferential surface 140A with a first shape and a second outer circumferential surface 140B with a second shape. The first outer circumferential surface 140A is disposed around the first container and first seal 118A, while the second outer circumferential surface 140B is disposed around the second container and second seal 118B. The first and second surfaces are separated by a slot 122. According to the embodiment shown in FIG. 11 , the first and second shapes are each generally elliptical with different radii. That is, the first shape has a radius R1 extending from the center of the first container that is less than a radius R2 extending from the center of the second container. Of course, the first and second shapes may be any suitable shapes, including a triangle, a rectangle, a polygon, a circle, or any combination thereof, and the present disclosure is not limited to such. In some embodiments, the first and second shapes may correspond to the shape of a port on an associated reservoir device or other medical device. That is, in some embodiments, the combined first and second shapes may be substantially identical to the shape of a port on the reservoir device. The combined shapes may be asymmetric due to differences between the first and second shapes.

[0079] However, it should be understood that the receptacle unit may be used with storage devices having differently shaped ports and is not limited to use with storage device ports having substantially the same shape as the receptacle unit, for example, the receptacle unit may be used with storage devices having rectangular shaped ports, square shaped ports, oval shaped ports, or any other suitable shape.

[0080] It should also be understood that different container unit shapes may be used with the storage devices shown in Figures 12 and 13. In some embodiments, the shape of the container unit does not match the shape of the storage device port. For example, the outer periphery may form a symmetrical oval or rectangular shape. In some embodiments, the container unit shape simply needs to be smaller than the shape of the storage device port in order to be received by the port.

[0081] In some embodiments, the reservoir device used in conjunction with the container unit is a reservoir bag. A hollow spike may be used to puncture the container unit and place the container unit in fluid communication with the reservoir bag. In some embodiments, fluid can be drawn from the container unit into a syringe, where the needle of the syringe will puncture into the container unit.

[0082] FIG. 12 depicts one embodiment of a medicated reservoir device 10. The medicated reservoir device includes a housing 12, a first fluid distribution system 300, a second fluid distribution system 350, and four ports 24 for receiving container units. In the embodiment depicted in FIG. 12, the medicated reservoir device is configured to deliver two medicated fluids, which may be delivered from up to four containers per fluid. The first medicated fluid may be packaged with the second medicated fluid so that each port can receive both medicated fluids simultaneously (i.e., each of the four container units may include two containers). According to this embodiment, the medicated fluids are not mixed, but rather are independently delivered to fluid interfaces 302, 352, which may connect to a fluid administration device, such as a syringe or infusion pump, that can deliver the fluids sequentially to a patient. The first and second medicated fluids may each be transported to each of the fluid interfaces by separate tubing. As shown in FIG. 12, the fluid interface may be removably connected to an interface holder 14 for storage and transport.

[0083] As shown in FIG. 12 , four ports 24 of the medicated storage device are exposed. Each port includes a recess 16 configured to receive a container unit having a container of medicated fluid for storage and / or administration to a patient. As shown in FIG. 12 , each port includes two spike assemblies 200. In each port, one spike assembly is connected to a first fluid distribution system and one spike assembly is fluidly connected to a second fluid distribution system. Thus, each port accommodates multiple containers of separate medicated fluid for storage and administration. In the embodiment shown in FIG. 12 , when a container unit is inserted into a port, the containers disposed within the container unit may be punctured by the spike assemblies 200, fluidly connecting each of the containers to one of the fluid distribution systems, which terminate in the fluid interfaces 302, 352.

[0084] As shown in FIG. 12 , each port 24 may include components configured to align an inserted container unit or otherwise simplify the medicated administration process. For example, the port may include a recess 16 formed in the housing 12 of the medicated storage device that allows the container unit to be guided by the port as the container unit is pushed onto the spike assembly 200 by the patient or medical professional. That is, a container unit with an outer circumferential surface shape complementary to that of the periphery of the port may be aligned and guided by the periphery of the port as each container of the container unit is pushed onto the spike assembly. The port may also include an insert 20 and a guide channel 22 configured to provide additional guiding and alignment surfaces for insertion of the medicated fluid containers. The insert 20 and the guide channel 22 may have shapes complementary to the shapes of the slot and inner wall of the container unit. Thus, the guide protrusions and guide slots may contact the slot and / or inner wall to guide and align individual containers placed within the container unit with the spike assembly 200. 12, the port includes at least one latch 18 configured to removably or permanently couple any received container unit to the port and prevent removal. In some embodiments, the latch may be configured to removably couple with the container unit. The port may include any suitable matching or locking feature, and the present disclosure is not so limited.

[0085] In some cases, it may be desirable to maintain the sterility of the container unit and / or medicated storage device by preventing subsequent use of the container unit. Thus, in some embodiments, the container unit and / or storage device may be configured for single use as a disposable device. That is, the container unit and / or storage device may be configured to hinder or prevent reuse of the medicated storage device. For example, as shown in FIG. 12 , the latch 18 of the medicated storage device 10 may be configured to substantially prevent removal of a container unit attached to the port 24. Thus, an operator (e.g., a patient or medical professional) may be unable to replace the container unit and initiate a second administration process. It should be understood that any other suitable components may be used to prevent multiple use of the container unit and / or storage device, including mechanical restraints and self-closing valves.

[0086] FIG. 13 depicts an exploded view of the container unit 100 of FIG. 1 when used with the storage device 10 of FIG. 12. As shown in FIG. 13, the container unit is inverted so that the bottom 124 of the container unit faces away from the port 24 of the storage device and is above the interface portion 144, including the edge 126. With the container unit in the inverted position, the openings (not shown) and stops of the first container 110A and the second container 110B face the spike assembly 200. The container unit lid and container seal have been removed so that the container unit is ready for connection to the storage device. As shown in FIG. 13, the interface portion 144 includes a slot 122 that aligns with the insert 20 and guide channel 22 of the port. The slot has a shape complementary to that of the insert and guide channel so that, in the position shown, the container unit can be connected to the port. If the container unit is not in the proper orientation shown, the insert may contact the container unit and resist connection of the container unit to the port. Similar to the insert and slot described above, the first and second outer circumferential surfaces 140A, 140B of the container unit interface portion are aligned with the recess 16 of the storage device. The recess 16 has a shape complementary to that of the first and second outer circumferential surfaces 140A, 140B so that the container unit can be properly guided and oriented as it is connected to the port. If the container unit is not properly oriented and aligned with the recess, the housing 12 of the storage device may contact the container unit and resist connection to the port.

[0087] As shown in FIG. 13 , the edge 126 of the container unit 100 may be configured to engage a latch 18 disposed within the port 24 of the storage device. The latch 18 may include a barbed end configured to deflect as the edge passes the barbed end, which may then return to its original position and engage the edge. Such an arrangement may allow the container unit to be fully inserted into the recess 16 while providing resistance to removal of the container unit. The latch is not limited to a barbed end; however, any suitable arrangement for securing the container unit to the storage device may be used. According to the embodiment of FIG. 13 , the port includes two latches disposed on opposite sides of the recess 16. In other embodiments, the port may include a single latch or more than two latches secured to the container unit; the present disclosure is not so limited.

[0088] FIG. 14 is a block diagram of one embodiment of a method for combining a container unit and a storage device. In block 400, a patient or a medical professional may remove a lid from the container unit to expose a first container and a second container of medicinal fluid. In block 402, the patient or a medical professional may remove a first seal and a second seal that cover a first stop on the first container and a second stop on the second container, respectively. In some embodiments, blocks 400 and 402 may be combined into a single step. For example, the lid may be coupled to the first seal and the second seal such that removal of the lid also removes the first seal and the second seal from the container. In block 404, the patient or a medical professional may align the outer circumferential surface of the carrier of the container unit with the port of the storage device. In block 406, the patient or a medical professional may align an insert of the storage device with a slot in the container unit. In some embodiments, the order of the steps in blocks 404 and 406 may be reversed, depending on the particular geometry of the container unit and the storage device. In block 408, the patient or medical professional may connect the container unit to the storage device at a port. Blocks 400-408 may be repeated as many times as necessary to arrive at a particular dosage of medicated fluid connected to the storage device. That is, additional container units may be connected to the storage device for increased dosages.

[0089] FIG. 15 is a cross-sectional view of the container unit 100 of FIG. 1 taken along line 15-15 of FIG. 1. As shown in FIG. 15 and discussed above, the container unit carrier 120 holds a first container 110A and a second container 110B using recesses 128A, 128B and container neck holders 132A, 132B. The first container includes a first stop 116A disposed within the first opening 110A, which is defined by a first plane. The second container includes a second stop 116B disposed within the second opening 110B, which is defined by a second plane. According to the embodiment shown in FIG. 15, the first plane and the second plane are coplanar (i.e., the first opening and the second opening are disposed at the same height). As shown in FIG. 15 , the lid of the container unit and the container seal have been removed. The extension 142 forms the top portion of the carrier, extending away from the container's internal volume. Each stop includes a first end 160A, 160B and a second end 162A, 162B, with the second end facing away from the container's internal volume within which the stop is disposed. According to the embodiment shown in FIG. 15 , the extension 142 extends away from the first container 110A's internal volume at least as high as the second end 162A of the first stop 116A. That is, the offset between the extension and the second end of the first stop is greater than or equal to zero. In the embodiment shown in FIG. 15 , the extension extends a distance A away from the container neck holder 132A. The extension may be configured to contact a storage device when the container unit is connected to the storage device. The extensions can resist force applied to the carrier bottom 124 so that any spikes or needles of the reservoir device do not extend further into the first container. Thus, the extensions can set a predetermined penetration depth for any spikes or needles that may extend into the first container. Such an arrangement can facilitate proper evacuation of the first container via the spikes or other couplings. For example, if the spikes are inserted too far into the container, the medicated fluid disposed therein may not be able to be fully extracted via the spikes.According to this embodiment, it may be desirable to have an optional internal channel of the spike located adjacent to or near the first end of the first stop so that the medicinal fluid can be completely extracted (i.e., drained) from the first container.

[0090] As can be seen from FIG. 15 , the second ends 162A, 162B of the first stop 116A and the second stop 116B of the containers 110A, 110B are positioned at the same height. That is, the second ends of the stops are positioned in the same plane, at a distance (i.e., the same distance in the vertical dimension) from the bottom 124 of the carrier 120. This is true according to the embodiment shown in FIG. 15 , regardless of the size difference between the containers 110A, 110B in the vertical dimension. As shown in FIG. 15 , the extension 142 extends a distance B away from the container neck holder 132B, which exceeds distance A, compensating for the container size difference and the position of the container neck holders 132A, 132B. As a result, the extension 142 of the carrier can extend at least as high away from the interior volume of the second container 110B as the second end 162B of the second stop 116B. That is, the extension 142 of the carrier may be offset from the second end of the second stop by a distance outward from the second end that may be greater than or equal to zero. As a further consequence, features of the container, such as a seal (not shown), may also be located at the same height. The alignment of the second ends of the seals at the same height may simplify the construction of the lid, facilitate its use, and potentially facilitate the administration of fluids placed within the container. Of course, the second ends of the stops (or other features) may be located at different heights, and the present disclosure is not so limited.

[0091] According to the embodiment shown in FIG. 15 , the extension 142 of the carrier forms at least a portion of the edge 126. Thus, in the embodiment of FIG. 15 , the edge 126 forms at least a portion of the top portion of the carrier. In other embodiments, the extension and edge may be separate and independent from one another. For example, the extension may not extend from the outer periphery, but rather from a central region of the carrier. While the extension 142 in FIG. 15 extends around a substantial portion of the outer periphery of the carrier, the extension may have any suitable arrangement such that the extension is at least flush with the second end 162A of the first stop 116A. For example, the extension may be formed as a post, spacer, or any other suitable standoff configured to resist forces that may over-insert the spike into the first container.

[0092] 15, the top portion of extension 142 may have a constant offset relative to at least one of the second ends of stops 116A, 116B. For example, extension 142 may form multiple top points or regions disposed in the same plane. Each of the multiple top points or regions may have an equal offset from stop second ends 162A, 162B in a direction away from the interior volume of container 110A, 110B. That is, extension 142 may form a flat top portion such that a predetermined penetration depth can be set for at least one of the stops at each of the multiple top points or regions of the carrier.

[0093] FIG. 16 depicts another embodiment of the container unit 100. Similar to the embodiment of FIG. 1, the container unit includes a first container 110A, a second container 110B, and a carrier formed from a first section 120A and a second section 120B. The container unit also includes a lid 150, which covers the openings of the first and second containers. In contrast to the embodiment of FIG. 1, the container unit of FIG. 16 has a second container 110B that is radially and longitudinally larger, with a correspondingly modified second recess 128B. While the second recess in FIG. 1 forms a perfect circle, the second recess 128B in FIG. 16 is cut into two partial arcs of a circle. Thus, the bottom 124 may only partially cover the lowest portion of the second container 110B.

[0094] FIG. 17 depicts a cross-sectional view of the container unit 100 of FIG. 16 taken along line 17-17 of FIG. 16. Similar to the embodiment shown in FIG. 15, the second end 162A of the first stop 116A is vertically aligned with the carrier extension 142. That is, the extension extends a distance A from the container neck holder 132A, resulting in an offset between the extension and the first stop second end that is approximately zero. Similarly, the second end 162B of the second stop 116B extends to approximately the same height as the extension 142. The extension 142 extends a distance B from the second container neck holder 132B, leaving the extension approximately the same height as the second stop second end. 17, the offset distance is approximately zero because the second end of the second stop is aligned with the carrier extension 142. Thus, the second end of the first stop and the second stop are disposed in the same plane.

[0095] FIG. 18 depicts yet another embodiment of the container unit 100. Similar to the embodiment of FIG. 1, the container unit includes a first container 110A, a second container 110B, and a carrier formed from a first section 120A and a second section 120B. The container unit also includes a lid 150, which covers the openings of the first and second containers. In contrast to the embodiment of FIG. 1, the second container 110B is smaller in the radial and longitudinal directions. As a result, the second recess 128B is smaller, while the bottom 124 is approximately the same size. Thus, the carrier is thicker around the second recess.

[0096] FIG. 19 depicts yet another embodiment of the container unit 100. Similar to the embodiments of FIGS. 1 and 16, the container unit includes a first container 110A, a second container 110B, and a carrier formed from a first section 120A and a second section 120B. The container unit also includes a lid 150, which covers the openings of the first and second containers. In contrast to the embodiment of FIG. 16, the second container 110B is larger in both the radial and longitudinal directions. As a result, the second recess 128B is even larger than that of FIG. 16 and forms two separate arcs, while the bottom 124 is approximately the same size. Thus, the carrier is thinner around the perimeter of the second recess, which allows for a larger volume of medicated fluid within the second container 110B.

[0097] FIG. 20 depicts yet another embodiment of the container unit 100. Similar to the embodiment of FIG. 1, the container unit includes a first container 110A, a second container 110B, and a carrier formed from a first section 120A and a second section 120B. The container unit also includes a lid 150, which covers the openings of the first and second containers. In contrast to the embodiment of FIG. 1, the second container 110B is larger vertically. As a result, the height of the container unit is larger, while the circumferential dimensions are approximately the same. Thus, the container unit of FIG. 20 may contain more medicated fluid for a given circumferential shape.

[0098] In some embodiments, the first and second sections of the carrier may each be made, in whole or in part, from a clear (e.g., transparent, translucent) material that allows a user to view the first and second containers through the first and second sections. In one example, the first and second sections may each be made from a plastic resin, such as a copolyester, that combines high visibility with acceptable mechanical properties. Of course, other materials that allow the first and second containers to be viewed through the first and second sections may also be used.

[0099] FIG. 21 depicts an embodiment of multiple container units 100A, 100B, 100C for use with the storage device 10. As shown in FIG. 21, each of the three container units is inverted and connected to a port 24 of the storage device. Thus, the container units are secured, and containers placed therein are fluidly connected to a fluid distribution system 300, 350, which terminates at a fluid interface 302, 352. The container units are supported by a port recess 16, which has a shape complementary to the outer circumferential shape of the container unit. In the embodiment of FIG. 21, the port 24 is uniformly sized to receive any container unit with a corresponding outer circumferential shape. That is, each of the container units shown has a matching interface portion suitable for fitting within the outer circumferential shape of the port. Thus, even if the container units hold different volumes of medicated fluid, they can be connected to the storage device. As shown in FIG. 21 , two container units 100A, 100C, each holding the same volume, are shown in conjunction with a container unit 100B having a smaller volume. The volumes of medicated fluid from each of the container units may be combined by a reservoir device and delivered to fluid interfaces 302, 352 to reach a specific dosage. In the embodiment of FIG. 21 , medicated fluid from a first container in each of the container units is combined and delivered at one fluid interface, and medicated fluid from a second container in each of the container units is combined and delivered at another fluid interface. Any suitable number of container units with any variation in medicated fluid volume may be used, alone or in combination, during the administration process. Additionally, any combination or mixing of medicated fluids may be performed by a reservoir device or other suitable medical device, resulting in delivery to one or more fluid interfaces; the present disclosure is not so limited.

[0100] While the present teachings have been described in conjunction with various embodiments and examples, it is not intended that the present teachings be limited to such embodiments or examples. On the contrary, the present teachings encompass various alternatives, modifications, and equivalents, as will be appreciated by those skilled in the art. Accordingly, the foregoing description and drawings are by way of example only.
