(21) As mentioned, the mobile container system 105 includes the drug rack 305, which is configured to manage the storage, access, and distribution of drugs. FIG. 3 shows a perspective view of an example embodiment of the drug rack 305. The drug rack 305 includes an outer housing 310 that is sized and shaped to contain and/or store one or more drug vials 315. The outer housing 305 can be any of a variety of shapes including the rectangular shape shown in FIG. 3. In a non-limiting example embodiment, the drug rack 305 has a size of 5 inches wide by 2.5 inches tall, by 2.5 inches deep and weighs no more than about 0.6 pounds. In another embodiment described below, the drug rack 305 is contained within or otherwise includes a housing with a lid that can be opened to exposed contents of the drug rack 305.

(22) In the illustrated embodiment, the drug rack 305 is sized to contain four drug vials 315, which can be of equal or varying size relative to one another. In an example, the vials can be 10 mL multi-dose or 2 mL single-dose vials although the size of the vials can vary. It should be appreciated that the housing 310 can be sized to contain any quantity of vials although the preference is that the quantity be limited so that the housing is of a size than can be transported and/or easily carried by a user. In an example embodiment, the housing 310 contains no more than three, four, five, six, and up to ten vials although this may vary.

(23) The housing 310 is configured such that it defines at least one slot or seat for each of the drug vials 315. The seats can be configured to receive therein a drug vial of various sizes, such as a large drug vial and a smaller drug vial. The drug vials 315 are arranged in one or more rows of drug vials as shown in FIG. 3 although the spatial arrangement of the drug vials can vary. A retaining member, such as a lock bar 320 is movably attached to the housing 310 such that, in a closed state, the lock bar 320, retains or secures the vials 315 within their respective seats in the housing 310. The lock bar 320 can move relative to the housing 310, such as in a pivoting or rotating manner, to an open state wherein the lock bar 320 does not impede or otherwise prevent the drug vials 315 from being removed from the housing 310. The lock bar 320 is positioned such that a vial, when seated in its seat, is interposed between the lock bar 320 and the seat so that the lock bar 320 prevents the vial from being removed from the seat when the lock bar is properly positioned.

(24) The drug rack 305 can include a single lock bar 320 that collectively secures all the drug vials 315 as shown, or it can include a separate, dedicated lock bar for each of (or a subset of) the drug vials in the drug rack 305. The lock bar 320 can be lockingly secured in the closed state such as via a mechanical or electromechanical lock for security of the drugs contained within the drug rack 305.

(25) With reference still to FIG. 3, the drug rack 305 can include a mounting clip 325 that is attached to the housing 310. The mounting clip 325 can be used to secure or otherwise mount the drug rack 305 to another object. FIG. 4 shows the mounting clip 325 and FIG. 5 shows the drug rack 305 mounted to a MOLLE as an example.

(26) FIG. 6 shows a bottom view of the drug rack 305. FIG. 7 shows a bottom view with the drug rack being partially transparent so as to illustrate internal components of the drug rack. As shown in FIG. 6, an opening or port 605 is associated with each of the drug vials 315 at the bottom wall of the housing. Each port 605 provides an accessway by which a user, such as a medic, can access the contents of the respective drug vial 315. Each port 605 can transition between an open state and a closed state. Port 605a is shown in the open state while port 605b is shown in the closed state. When the port is in the open state, the contents of the respective drug vial are accessible by the user. When in the closed state, the contents of the respective drug vial are inaccessible by the user, as described below. The port(s) can include or be coupled to mechanical and/or electrical components, such as one or more electro-mechanical servo devices that enable control of the port(s).

(27) The transparent view of FIG. 7 shows an example mechanism by which the ports 605 can transition between the open and closed states. Each port 605 has an associated door 705 that is movably positioned within the drug rack 305. Each door 705 can slidably transition between the closed state wherein the door 705 covers or otherwise blocks the respective port, and an open state wherein the door 705 does not cover or otherwise block the respective port. In FIG. 7, the door 705a is in the open state while the remainder of the doors 705 are in the closed state.

(28) The drug rack 305 can include electromechanical components that are coupled to the doors 705 and the lock bar 320 for controlling these components between the open and closed states. The drug rack can also include software to automatically control these components, such as via interaction with a user and/or based upon satisfaction of predetermined conditions. In addition, the drug rack 305 can include features such a lights, sounds, and tactile feedback to provide the user with indications as to the availability of the drug, type of drug, dosage information for the drug, how much drug has been used, etc.

(29) The drug rack can include, for example, one or more multi-color LED drug indicator lights that provide a color coded back light depending on the type of drug contained in the vials. For example, the lights can be color-coded such as Blue/Pain, Orange/Sedative, Purple/Paralytic.

(30) The software can be coupled to a user interface, such as the example user interface shown in FIG. 8. The user interface can include data related to the drug vials and can also include features that enable the user to interact with the drug rack, such as to open/close/lock/unlock features of the drug rack. The access doors and/or the lock bar can be configured via software to automatically open after the care provider selects a drug to administer via the user interface. The software can also include a weight-based recommended drug calculator that can read weight automatically from a digital/wireless scale coupled to the system. The drug rack software can also automatically detect the drug type in a vial via a bar code scan and also the volume/dosage pulled from a vial.

(31) FIGS. 9 and 10 show perspective views of another embodiment of the drug rack 305. This embodiment includes an outer housing 910 with a movable lid 920 that transitions between an open and closed state. When in the closed state, the lid 920 covers the drug vials so as to prevent access to the drug vials. When in the open state, the lid does not cover the drug vials and does not prevent access to the drug vials. Rather, the lid provides a platform or surface that provides a location where a user can place instruments, such as needles, when accessing the drug vials. FIGS. 9 and 10 show the lid 920 in the closed state. In an example embodiment, the lid 920 is at least partially made of a transparent material such that a user can view the drug vials contained therein even when the lid is closed. As shown in FIG. 9, the drug rack 305 can include components such as a power (or “on/off”) switch 925. The drug rack 305 can also include a port 930, such as a USB port, for charging the drug rack and or coupling a USB device to the drug rack 305.

(32) As shown in FIG. 9, the outer housing 910 and lid 920 can include an interface such as a pair of holes through which a tie element can be inserted and tied for locking the lid closed. The outer housing 910 can also include other components such as magnets for securing the lid 920 in the closed state.

(33) As shown in FIG. 10, the drug rack 305 can include a tightening mechanism 1005 that a user can actuate to tighten and to also release tension on one or more elongated members such as cables or wires 1012 (or other actuation component) that individually or collectively serve as a retaining member or locking element for vials contained within the drug rack 305, as described more fully below. The wires 1012 wrap around vials contained within the drug rack 305 and can be tightened to lockingly secure the vials within the drug rack 305. In an embodiment, the tightening mechanism includes a ratcheting device that can be actuated, such as via rotation or other movement, to place the wires in tension and/or release the wires from tension. In a non-limiting example, the ratcheting device includes a rotatable knob.

(34) FIG. 11 shows the drug rack 305 with the lid 920 in the open state wherein the lid is open relative to the outer housing 910 so as to expose the vials 315. In FIG. 11, the drug rack 305 is in an example orientation in which a user, such as a medic, can use the drug rack 305. The lid 920 is coupled to the outer housing 910 via one or more hinges 1105 that enable the lid 920 to rotate between the open state and the closed state. It should be appreciated that other mechanisms aside from rotatable hinges can be used to enable the transition of the lid between the open and closed states.

(35) The lid 920 defines a flat or substantially flat, horizontal platform or surface 1110 that defines a space where a user, such as a medic, can rest his or her hands as the vials are being accessed. The surface 1110 also provides a platform upon which the user can also place one or more items, such as a needle. The flat surface 1110 aids in the medic inserting a needle into a vial such as during a high vibration environment. The lid 920 and/or the outer housing 910 can include one or more securing elements, such as magnets, to maintain the lid 920 in an open or closed state. The vials 315 are positioned relative to the surface 1110 such that ends of the vials 315 are facing and immediately adjacent to the surface 1110. That is, an open or access portion (such as where a needle can be inserted) of the vial 315 is immediately adjacent the surface 1110, such as abutting and/or contacting the surface or within an inch or two of the surfaces. This permits the user to easily access both the surface 1110 and the vials 315.

(36) As mentioned with respect to the prior embodiment, each vial 315 is seated within a corresponding slot or seat. When seated as such, the drug rack 305 orients each vial 315 so that a top portion or access portion of the vial is presented to a user for convenient access. The seat can be shaped to correspond or complement the shape of the vial so that the vial can sit flush within the respective seat. Each vial has a corresponding saddle 1120 that abuts, grabs, or otherwise stabilizes or the vial when seated in its seat. The saddle 1120 can be tightened about its respective vial to lock the vial within its seat. The saddle 1120 can be made of a material that is flexible or malleable such that the saddle can conform to the shape of the respective vial when the saddle is tightened over the vial.

(37) As mentioned, the saddles 1120 can be tightened about their respective vials to lock the vials within their seats. In this regard, the wires 1012 (FIGS. 10 and 11) are threaded through the saddles and also threaded through at least a portion of the drug rack so as to secure the drug vials 315 relative to the drug rack. The wires 1012 can be placed in tension to exert a force that constrains the saddles 1120 and their respective vials in place within their seats. The actuator 1005 (FIG. 10) can be used to tighten and release the tension on the wires 1012. In a non-limiting embodiment, the actuator 1005 is part of a tightening mechanism, such as the tightening mechanism described in U.S. Pat. No. 5,934,599, which is incorporated herein by reference in its entirety.

(38) FIG. 12 shows another view of the drug rack 305. The lid and a portion of the outer housing are not shown in FIG. 12 for clarity of illustration. As mentioned, the drug rack 305 can include one or more multi-color LED drug indicator lights that provide a color coded back light depending on the type of drug contained in the vials. As shown in FIG. 12, the one or more LEDs 1205 can be located on the drug rack 305 at or near a bottom region of each vial 315. When illuminated, an LED emits light through a clear bottom region of the drug vial. The light refracts in the material of the vial (such as glass) and within the material inside the vial (such as liquid) so as to make the vial glow. The drug rack can include infrared capabilities and/or night vision capabilities that utilize infrared LEDs for illumination of the vial(s).

(39) In a method of use, a user, such an emergency medic, is transported via a mobile vehicle 110 to a location that requires medical treatment for a patient. The location can be an emergency location such as a disaster site or a battle site. The user can carry the mobile container system 105 or a portion thereof during transport or can also mount the mobile container system 105 on the vehicle. Upon reaching a location, the user can carry the mobile container system 105 or a portion thereof on his or her body without assistance from a transport device such as a cart. The user can then treat a patient by accessing the user interface. The user can gain access to the contents of one or more drug vials of the drug rack via interaction with the user interface, which may request credentials or other security access requirements. Upon accessing the content(s) of the drug vial(s), the mobile container system 105 can locally or remotely records or otherwise memorialize data related to the drug or contents accessed via the vial. For example, the system can record, via the drug rack, that a specific drug was administered at a certain time, the time the drug was given, the name or other data related to the patient, the dosage amount, etc.
