## Background
RELATED APPLICATION
This application claims priority to U.S. Pat. App. Ser. No. 61/349,878 filed on May 30, 2010 and entitled: “Medication Identification Encoding and Verification”, the contents of which are hereby incorporated by reference.


FIELD
The subject matter described herein relates to a medication identification, encoding and verification for use in scanning, verifying and/or marking medication containers so the medications in those containers can be properly identified and documented during the process of patient medication preparation, administration, and disposal. Medication containers can include syringes, bags, vials, medication transfer apparatus as well as medical packaging with marking applied during various manufacturing and pharmacy processes.
BACKGROUND
Many health care procedures involving the preparation, administration and wasting of medication involve a clinician manually reading labeling applied to various medication containers. Such an arrangement is fraught for user error resulting in over-medication, under-medication, administration of non-compatible medications and/or administration of medications to which a patient is allergic. In addition, problems also arise in properly labeling medication containers during manufacture and preparation (whether in the pharmacy or otherwise). Proper labeling is of particular import when there are multiple components bundled together.
SUMMARY
In one aspect, data characterizing medication within a medication container is received. Thereafter, an identifier encapsulating data characterizing the medication is generated and applied to the medication container. The identifier can be positioned such that it is automatically readable by a medication administration device when the medication is administered to a patient and/or by a medication disposal device when the medication is wasted.
The medication container can take a variety of forms. The medication container can be a syringe comprising a barrel portion and a tip portion comprising a fluid outlet such that the identifier is applied to the tip portion. The tip portion can comprise a cylindrical or conical outer surface terminating at the fluid outlet such that the identifier is applied to the outer surface. The tip portion can comprise a Luer lock fitting such that identifier is positioned on the Luer lock fitting.
The medication container can be a vial having a stopper or a corresponding stopper closure to which the identifier is applied. The medication container can be a medication bag containing a medication solution having a Luer fitting and/or a spikeable port to which the identifier is applied. The medication container can be an envelope having a Luer fitting or a tubing set extending therefrom to which the identifier is applied. The medication container can comprise a fluid transfer device for transferring the medication from a first receptacle to a second receptacle. The medication container can comprise packaging including a medication receptacle containing the medication. The medication container can be a fluid tubing set having a fluid outlet such as a Luer fitting to which the identifier is applied.
The medication administration device can take a variety of forms. For example, the medication administration device can comprise: a housing, a medication port accessible via an outer surface of the housing, an identification sensor disposed within the housing to generate information indicative of contents of the medication container when the fluid outlet of the medication container is fluidically coupled to the medication port, and a transmitter disposed within the housing and in communication with the identification sensor to transmit the information generated by the identification sensor to a remote data collection system.
The encapsulated data can comprise a reference to data accessible via a communications network. In such cases, the encapsulated data can include a a Uniform Resource Locator, a database path, a pointer to a look-up table, or a file path such that the medication administration device accesses such remote information (which can be used, for example, for more informed patient treatment, etc.). In addition or in the alternative, the medication administration device can comprises a memory storing data corresponding to the encapsulated data which is accessed when the medication administration device reads the identifier.
The encapsulated data can be formatted using an industry standard representation of the medication being characterized or a proprietary representation of the medication being characterized. The referenced data accessible via a communications network can include one or more of: an NDC code (National Drug Code), a segment of the NDC code identifying the drug product, a segment of the NDC code identifying the drug package, a unique identifier code, a human readable alphanumeric, a machine readable code, a name of the medication, a manufacturer of the medication, a re-packager of the medication, a distributor of the medication, a strength of the medication, a dosage form of the medication, dose instructions for the medication, administration instructions for a specific patient, medication formulation, medication package form, medication package size, medication contained volume, medication package serial number, medication lot number, and medication expiration date. The encapsulated data can additionally or alternatively also include such information.
The identifier can take a variety of forms. For example, the identifier can be any of: optical identifiers, magnetic identifiers, RFID identifiers, and mechanically encoded identifiers. The identifier can be etched on an outer surface of the medication container. The identifier can be a mechanical element secured to or extending from the medication container. The identifier can include a coded disc or coded ring secured to the medication container.
The medication container can be bundled with at least one other item (e.g., second medication container, fluid adapter, tubing set, packaging, etc.) bearing a second identifier corresponding to the identifier. In such cases, it can be verified, after the bundling, that the identifier on the medication container corresponds to the second identifier on the at least one other item.
In a further aspect, data is read from a medication source characterizing medication contained by the medication source. Thereafter, an identifier encapsulating data characterizing the medication is generated and is applied to a medication container filled or to be filled with the medication from the medication source. The identifier can be positioned such that it is readable by a medication administration device when administering the medication to a patient or when disposing the medication without deliberate effort on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device or the medication wasting device.
In a further aspect, a medication identification encoding and verification apparatus is provided that includes a medication information source, an identification information reader (ID reader), an identification information writer (ID writer), a verification method to check the read information and a medication identification target (ID target). The ID reader includes a detector, scanner or imaging element to receive the medication identification information. The ID writer includes a marking element to deposit or encode identification information onto the ID target. The ID target receives the encoded identification information mark, image, code or other information rich media content. If the medication container is a syringe, the encoded information on the target is positioned such that it can be read by a medication administration device when administering the medication to a patient without deliberate effort on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device.
In another aspect, a medication identification encoding and verification apparatus is provided with a second ID reader, a verification comparator, an identification information verification writer (IDV writer) and a second identification information target on packaging materials. The second ID reader includes a scanner element to receive medication information from a medication container or associated medical packaging. The verification comparator includes means for comparing desired identification information to medication container identification information. The IDV writer includes a marking element to deposit or encode identification information on a second ID target. The second ID target receives the second identification information mark. The second ID target can be packaging material. A read-write instrument can be provided for reading a medication identification code source and writing information to a target for encoding the target with the medication identification information used, for example, in a pharmaceutical manufacturing facility. In a further variation that can be used in a pharmaceutical repacking operation or in-hospital pharmacy, the reader can identify medication information from a multi-dose container and the writer can then encode single or partial dose information on the target. In this variation, the written information can be different from the original read information in that it can indicate smaller volumes, lower concentrations or be a patient specific dose. Multiple writes can be made on multiple targets to encode information about aliquots of medication written onto multiple single dose containers.
The information reader aspect of the read-write instrument can be any one of a linear bar-code reader, a 2D barcode reader, a magnetic strip reader, an image capture device, a camera, a manual data input information string, a stored alpha numeric character string, a unique symbolic identifier.
The information writer aspect of the read-write instrument can be any one of a laser, a printer, a hot stamp, a magnetic coding element, an electronic coding element, an RFID writer, a printed label, a coded disc, or coded ring element to be affixed to a medication container or packaging.
The information target can be any one of a syringe including but not limited to an empty and/or a prefilled syringe, a bag, a vial, a medication transfer apparatus including but not limited to an fluid administration set, a vial transfer apparatus, packaging, a medication container ID label marking element or coded disc, or coded ring to be affixed to the medication container. The information element can be applied to the tip portion (i.e., the portion of the medication container having the fluid outlet and a diameter smaller than or equal to the chamber of the medication container, etc.) or fluid outlet of the medication container.
The medication container and or the vial transfer apparatus can be enveloped in a sterile pouch (i.e., enclosure, etc.). The sterile pouch can contain information indicative of the encoded information on the information transfer element. The medication information transfer element can be part of a kit that also contains the vial and medication instructions for use. The kit can be manufactured complete by a pharmaceutical company including the medication in the vial and the information transfer apparatus. The kit can be packaged by a local pharmacy, a pharmaceutical repackaging operation or an in-hospital pharmacy and can include a pharmaceutical company packaged vial and the information applied to a fluid transfer apparatus.
In the pharmacy and/or pharmaceutical repackaging kit configuration the pharmacy can match and verify the medication information on the vial and vial packaging with the medication information on the transfer apparatus packaging and the information transfer element. The encoded information on the transfer apparatus can be positioned such that it can be read by a medication administration device when administering the medication to a patient without deliberate effort on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device. Once matched and verified the pharmacy can join the vial and information transfer apparatus into a secondary package and label the kit. The secondary package can provide a tamper evident element providing assurance of maintaining the matched elements. The secondary package can contain pharmacy specific information including lot number, packaging date, medication expiration date, dosage, patient information and/or container serial number.
In a pharmacy and/or pharmaceutical repackaging operation, the read-write instrument can be provided for reading a medication identification code source and writing information to multiple targets with the medication identification information encoded on multiple medication containers. In this variation, a multi-dose medication container (vial, Act-O-VialTM, bag, bottle, ampoule, syringe, etc.) is provided to the pharmaceutical filler. Using the method, the pharmaceutical filler can encode multiple containers, or transfer elements, sub-dividing the contents of a multi-dose container into more than one dose administration sub-container. The multi-dose container information can be read and verified with an identification code. Then multiple sub-containers can be written (encoded) with sub-container information. The written sub-container information can contain the same or different information than the multi-dose medication container. The sub-container information can include any information useful for characterizing the contents of the sub-container (such as the data described above). If the sub-container is a syringe, the encoded information on the target can be positioned such that it can be read by a medication administration device when administering the medication to a patient without deliberate effort on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device.
The encoded information can be selected from a group comprising: optically encoded information, optical image information, magnetically encoded information, radio frequency detectable information, and mechanically detectable information. The encoded information can include a unique identifier, NDC information, dose, concentration, package serial number, lot number, expiration date. The encoded information can be based on an industry standard representation of information content or a proprietary representation of the content.
The current subject matter provides many advantages. For example, by allowing for the automatic identification of the contents of medication containers (whether during administration of such medication or as part of a verification process during manufacture/preparation), medication administration errors can be greatly reduced. In addition, adverse effects from drug allergies and incompatible medications can be significantly minimized by providing a medication container that can be automatically identified. Providing a medication container labeled in a way that is automatically readable by a medication administration device without deliberate effort on the part of the clinician, greatly reduces the possibility of human error or that the label identification step will be skipped or adversely abbreviated in an effort to focus on immediate patient care needs. Lastly, proper record keeping can be maintained with regard to wasted medication (which is especially important with regard to controlled substances).

DETAILED DESCRIPTION
FIG. 1A is a diagram illustrating a medication identification information read and write apparatus 2 that can be used to implement a medication container encoding and identification method. Apparatus 2 can include a read-write instrument 4 that can include one or more information readers 10, an information writer 16 and an information target 8. With such an arrangement, an entity or device such as a pharmaceutical manufacturer, a pharmaceutical repackager, a local pharmacy or an in-hospital pharmacy can access or read medication identification information 14 from medication code source 6. This read medication identification information 14 can be subsequently written, applied (e.g., deposited, encoded, etc.) in the form of medication identification information 20 onto or into information target 8 for the purpose of encoding target 8 at the fluid outlet. The encoded medication identification information on the target (sometimes referred to herein as an “identifier”) can be positioned such that it can be read by a medication administration device when administering the medication to a patient without deliberate effort on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device. This is further described below in connection with FIG. 10.
The medication identification information 20 can be displayed on a variety of locations on an information target 8 (i.e., a medication container, etc.). For example, when the information target 8, the medication identification information 20 can be positioned on a tip of the syringe. More specifically, in some implementations, the medication identification information 20 can be placed on a tapered portion of the tip, a Luer lock fitting on the tip, and a portion of the tip interposed between the tapered portion and the cylindrical chamber of the syringe.
The current subject matter is applicable to a wide variety of medication containers. Examples of medication containers include: a pre-filled or empty needle-less syringe having a fluid outlet at a tip of the syringe, a vial having a fluid outlet corresponding to the stopper at the vial closure, a bag containing a premixed solution having a Luer fitting connector or an IV set spikeable port, an envelope (e.g., disposable, rigid, semi-rigid or flexible envelope, etc.) having an integral Luer fitting or tubing extended therefrom, a fluid transfer device used with medication vials having a luer fitting connector, and/or a fluid delivery tubing set having an integral luer fitting at one end of the tubing.
The medication code source 6 can be/include any one or more of a barcode (one or two dimensional), an optical image (e.g. picture, symbol, image, hologram, etc.), an NDC code (National Drug Code), a segment of the NDC code identifying the drug product, a segment of the NDC code identifying the drug package, a unique identifier code, human readable code, a machine readable code, a manually entered code or other codes that can be created to uniquely identify one or more of a medication's name, manufacturer, re-packager, distributer, strength (concentration), dosage form, dose instructions (whether generic for all patients or specifically prescribed for a particular patient), formulation, package form, package size, contained volume, package serial number, lot number, expiration date.
Additional complementary information can also be included within the medication code source 6 such as a reference to a database or document (via, for example, a URL, etc.) which can include additional information regarding the medication such as how it interacts with other medications and/or information regarding medications that are often administered along with the specified medication. As an example, before and/or coincident to the medication being administered, such complementary information may be accessed by a reader (whether at the point of administration or otherwise) so that additional information can be presented regarding the medication (including which medications should not be administered concurrently). In addition, in some implementations, it can be determined whether there is a possibility of an adverse reaction if the medication is delivered (whether via overmedication or interaction with previously delivered medications or due to some potential patient adverse condition). Such complementary information can also identify other medications that are often administered with the identified medication (especially in the case of complex protocols).
During use, the operator of read-write instrument 4 first determines which medication code source 6 is to be used and positions it in range of reader 10. Alternately, the operator can manually enter medication code source 6 information by using user interface 26. Secondly, the operator positions target 8 in range of writer 16. This positioning of target 8 may be a manual process or facilitated by automated equipment. The scanner element 12 of the reader 10 reads medication code source 6 and produces read information 14. Instrument control 24 receives read information 14 and prepares for a writing operation. Writer 16 receives read information 14 from instrument control 24 and writing element 18 of the writer 16 produces written information 20 to be written or deposited on target 8's fluid outlet 22. Writing element 18 can be one of a laser writer, a hot stamp, a printer, a magnetic encoder, an electronic data packet message, or a surface treatment facilitating optical, magnetic, electronic or proximity recognition. Once written, target 8 is encoded with information from medication code source 6.
As a first alternative, the writer 16 can deposit the encoded information on an adhesive backed element which can then be applied to target 8 (e.g., an RFID tag or other machine readable label applied to target). As a second alternative, writer 16 may apply a coded article such as a coded ring to target 8. As a third alternative the coded information or article can be radially written on the syringe surface 50 or take the form of coded disc 52 applied to surface 50.
FIG. 1B is a diagram illustrating a medication identification information read and write apparatus 2 for use with a vial. Similar to FIG. 1A, apparatus 2 can include a read-write instrument 4 that can include one or more information readers 10, an information writer 16 and an information target 30. With such an arrangement, an entity or device such as a pharmaceutical manufacturer, local pharmacy or in-hospital pharmacy can access or read medication identification information 14 from medication code source 6. This read medication identification information 14 can be subsequently written, deposited or encoded in the form of medication identification information 20 onto or into information target 30 for the purpose of encoding target 30 at the fluid outlet (vial septum, stopper or stopper closure).
Similar to FIG. 1A, additional complementary information can also be included within the medication code source 6 such as a reference to a database or document (via, for example, a URL, etc.) which can include additional information regarding the medication such as how it interacts with other medications and/or information regarding medications that are often administered along with the specified medication.
As a first alternative, the writer 16 can deposit the encoded information on an adhesive backed element which can then be applied to target 30 (e.g., an RFID tag or other machine readable label applied to target). As a second alternative, writer 16 may apply a coded article such as a coded disk 52 to target 30. As a third alternative the coded information or article can be radially written on the vial surface 54 in a pattern similar to disc 52.
FIG. 2 is a diagram illustrating an alternative medication identification information read and write apparatus. In this variation, the scanner element 12 of reader 10 reads medication code source 6a from vial 30 and produces read information 14. Instrument control 24 receives read information 14 and prepares for a writing operation. Writer 16 receives read information 14 from instrument control 24 and the writing element 18 of writer 16 produces written information 20 to be written or deposited on target 8a's fluid outlet 22a. Writing element 18 can be one of a laser writer, a printer, a magnetic encoder, an electronic data packet message, or a surface treatment facilitating optical, optical image, magnetic, electronic or proximity recognition. Once written, target 8a is encoded with medication code source 6a's information. In this variation, target 8a is part of vial adapter and ID transfer element 32 designed for use with empty container 34 (shown here as a syringe) for the withdrawal and transfer of medication to a patient. As an alternative, the writer can deposit the encoded information on a adhesive backed element which can then be applied to target 8a. As a second alternative, writer 16 may apply a coded article such as a coded plastic ring to target 8a. 
Other variations of medication containers and information targets can be incorporated that use various forms of medication code source 6a to provide information about the contents of the container and different target 8a with alternate fluid outlet 22a configurations. Targets can be encoded as separate parts and then grouped with other parts as assemblies.
The apparatus and process depicted in FIG. 2 customizes medication vial 30 to improve accuracy and safety of medication delivery. Vial 30 can be customized to be utilized by a self-auditing medication delivery system including a fluid input (not shown) that is coupled to a patient. During medication delivery to a patient, fluid outlet 22a is coupled to container 34 (e.g., a syringe). Fluid outlet 22a can be coupled to a fluid input (not shown) and then medication within container 34 is dispensed through fluid outlet 22a and into the fluid input. The fluid input (not shown) includes a reading device that reads encoded information 20 from fluid outlet 22a and can then utilize the information 20 to verify that a type and quantity of medication delivered by container 34 is proper for the patient. Thus, the current subject matter provides an advantageous way of customizing medication containers to enable a verification of proper medication delivery.
In a further implementation, vial 30 can be customized to provide a particular dosage of medication for a patient. Container 34 may be configured to hold a fraction of the entire volume of medication held in medication vial 30 as will be discussed later regarding FIG. 7. Information 20 may include information that is indicative of a dosage to be delivered to the patient from container 34. Such an implementation is advantageous in that it allows customization of medication to enable dosing to a particular patient without error. One example of such customization may be providing a dose for pediatrics or for a patient of a given weight class. In another variation, container 34 may be a “multi-dose” syringe configured to hold multiple doses of medication from vial 30. In yet further variations, medication in container 34 may be diluted and information 20 may additionally be indicative of dilution parameters. In yet further variations, medication in container 34 may be divided into multiple sub-container targets and repackaged by a pharmacy as will be discussed later.
FIGS. 3, 4 and 5 illustrate arrangements to read encoded medication information from various medication code sources and encoded targets and to verify their identity and write identifying information on packaging. FIG. 3 illustrates a first variation of apparatus 2 wherein the medication container is a prefilled or empty syringe. In this case medication code source 6 is read by reader 10 providing a desired identification. A second reader 40 (or a second read operation/position of first reader 10) can scan medication code source 6a and produces read information 42. Instrument control 24 compares information 14 to information 42 and verifies that their identity matches. Writer 16 receives information 42 from instrument control 24 and writing element 18 writes information 44 onto package 46. A human readable indication of the verification, “V”, can be part of written information 44. Package 46 can be a box, envelope, pouch or other medical product packaging forming fully packaged and labeled syringe 48. Alternately, reader 10 can scan medication code 6a instead of medication code 6 and reader 40 can scan encoded information 22 instead of medication code source 6a. Here, instrument control 24 compares medication code 6a to information 22 and verifies identity before writing information 44.
FIG. 4 describes a second variation of apparatus 2 wherein the medication container is vial 30 to be used with vial adapter and transfer apparatus 49. In this case medication code source 6 is read by reader 10 providing a desired identification. A second reader 40 (or a second read operation/position of first reader 10) scans medication code source 6a and produces read information 42. Instrument control 24 compares information 14 to information 42 and verifies their identity. Writer 16 receives information 42 from instrument control 24 and writing element 18 writes information 44a onto package 46a. A human readable indication of the verification, “V”, can be part of written information 44a. Package 46a can be a box, envelope, pouch or other medical product packaging forming fully packaged vial adapter and transfer apparatus 49. Alternately, reader 10 can scan medication code 6a instead of medication code 6 and reader 40 can scan encoded information 22a instead of medication code source 6a. Here, instrument control 24 compares medication code 6a to information 22a and verifies identity before writing information 44a. 
FIG. 5 is a third variation of apparatus and method 2 wherein the medication container is vial 30 to be used with vial adapter and transfer apparatus 49. In this case medication code source 6a is read by reader 10 providing a desired identification. A second reader 40 (or a second read operation/position of first reader 10) scans medication code source 6b and produces read information 42. Instrument control 24 compares information 14 to information 42 and verifies their identity. Writer 16 receives information 42 from instrument control 24 and writing element 18 writes information 44b onto package 50. A human readable indication of the verification, “V”, can be part of written information 44b. Package 50 can be a box, envelope, pouch or other medical product packaging forming fully packaged vial 30 and vial adapter and transfer apparatus 49. Alternately, reader 40 can scan information 22a instead of medication code 6b. Here, instrument'control 24 compares medication code 6a to information 22a and verifies identity before writing information 44b. 
FIG. 6 is a process flow diagram relating to the use of a medication identification encoding and verification apparatus 2 such as is shown in FIG. 5.
Step 1—Initialize instrument 4, locate medication code source 6a, initialize first reader 10; locate, scan and read medication code source 6a, and send medication code 6a to instrument control 24.
Step 2—Locate encoded element 6b or 22a, initialize second reader 40, scan and read encoded element, and send information to instrument control 24.
Step 3—Compare first read information (e.g., medication code 6a) to second read information (encoded element 6b or 22a) and verify information identity. Reject container or transfer element if there is not a match.
Step 4—Locate packaging element 46b, initialize writer 16, write verified information 44b, and repeat from step 1 thru step 4 if needed/desired.
FIG. 7 is a diagram illustrating a fourth variation medication identification information read-write and verification apparatus and method. This variation can be used in a pharmacy to read information from multi-dose medication container 60 and write information 20 onto multiple medication containers 62, 64, 66, 68, 70 (or onto multiple medication transfer elements 8a with cap 82 and attached to medication containers 72, 74, 76, 78, 80 as shown in the upper left). Encoded information 22A, 22B, 22C, 22D, and 22E can be written multiple times onto multiple containers 62, 64, 66, 68, 70 (or transfer elements 72, 74, 76, 78, 80) respectively. Any number of multiple doses and multiple medication containers can be used; there are five containers (A-E) shown in this example. The written information 20 can be the same for each medication container or it can be different. When different, the pharmacy operator can use user interface 26 to customize information 20 which can contain the same or different dose amounts (dose volume, concentration, etc.), different patient identifiers, different serial numbers, etc. In multi-dose container 60 arrangements, the reader 40 and/or instrument controls 24 can record the amounts introduced into each medication container 62-70 (or 72-80) and/or the amount remaining in the multi-dose medication container 60. This recorded information can be used for pharmacy records.
The method and apparatus of FIG. 7 depicts customization of medication container 60 for dosages that are smaller than the amount of medication held in medication container 60. This customization can provide a convenience to a caregiver and avoids error. A fluid receiving port (not shown here but can be seen in FIG. 10) coupled to a patient includes a reader that is configured to read the information 22 to verify and record a proper dose as being provided to a patient. The method and apparatus depicted in FIG. 7 along with the fluid receiving port connected to a patient and medication container coded fluid outlet reader provides an effective combination of dosage customization and electronic auditing to prevent error and to provide an automated form of electronic record keeping. The encoded information 20 on the target can be positioned such that it can be read by a medication administration device (fluid receiving port) when administering the medication to a patient without deliberate effort or work flow interruption on behalf of a clinician to facilitate information transfer between the medication container and the medication administration device.
FIG. 8 is a process flow diagram relating to the use of a medication identification encoding and verification apparatus 2 such as is shown in FIG. 7.
Step 1—Initialize instrument 4, locate medication code source 6, initialize first reader 10, locate, scan and read medication code source 6, and send medication code 6 to instrument control 24.
Step 2—Locate multi-dose vial 60, initialize second reader 40, scan and read multi-dose code 6a, and send information to instrument control 24.
Step 3—Compare first read information (e.g., medication code 6a) to second read information (code 6a) and verify information identity. Reject multi-dose container if there is not a match.
Step 4—Locate medication container, customize information 20 as required, initialize writer 16, write information 22A, and repeat from steps for additional containers B-E and information 22B-E as needed/desired. When all containers are encoded, END the process.
FIG. 9 is an alternate process flow diagram to that shown in FIG. 6 relating to the use of a medication identification encoding and verification system 2 such as is shown in FIG. 1. The process can be organized in any number of sequential or parallel steps to accomplish the read ID Code and write ID Code method. One such process is described showing the application of the ID Code to an empty container before a medication is filled into the container. Other process variations can be envisioned that fill the medication into the container before the ID Code is written onto the container (not shown).
Step 1—Prepare empty containers by application of encoded information element and prepare medication for container filling. Empty medication containers are received and inspected for use. Identification ID Code element is received and prepared for application. The ID Code element is written (applied) to the empty container (syringe, vial, bag, etc.). Medication is received and the medication ID Code determined. The ID Code is associated with the medication.

Step 2—Empty encoded containers and coded medication are delivered to an assembly operation. Prior to filling the empty containers with medication, the identity of the medication ID Code can be verified to determine if the ID Code on the empty container is the same as that associated with the medication. If they are the same, proceed to the filling operation. Each and every medication container can be verified or a lot sample can be verified.

Step 3—Empty encoded containers and coded medication are prepared for the filling process. Medication is filled into the empty containers.

Step 4—After filling the empty containers with medication, the identity of the medication ID Code can be verified to determine if the ID Code on the filled container is the same as that associated with the medication.

FIG. 10 illustrates caregiver workflow for administration of medication from the encoded medication container 8. A patient is receiving fluid delivery through an administration tubing set. A fluid receiving port for medications is attached to the administration tubing close to the patient. During execution of medication delivery, a health care provider obtains a medication container 8 from storage (medication dispensing unit, medication cart, medication kit, etc.). The health care provider takes the medication to the patient and inserts the medication container into the fluid receiving port. Upon attachment the fluid receiving port identifies the medication ID code 20 and transmits the information to an Information Capture and Recordkeeping System. The health care provider then administers the medication to the patient and the medication information encoded within the label is transmitted to the Information Capture and Recordkeeping System, time stamped and recorded. In addition, in some implementations, remaining medication is wasted/disposed in a Medication Wasting Device which can read the medication ID code 20 when the medication container 8 is coupled thereto.
FIG. 11 is a process flow diagram illustrating a method 1100 in which, at 1110, data characterizing medication within a medication container is received. Thereafter, at 1120, an identifier encapsulating data characterizing the medication is generated. This identifier is applied, at 1130, to medication container and is positioned such that it is automatically readable by a medication administration device when administering the medication to a patient and/or automatically readable by a medication wasting device when the medication is disposed therein (i.e., the identifier is read without deliberate effort on behalf of a clinician administering the medication to facilitate information transfer between the medication container and the medication administration device).
Features and functions of a sample medication container encoded fluid outlet and the use of same by a medication injection site/medication administration device are detailed in the U.S. patent application Ser. Nos. 12/614,276, 12/765,707, and 12/938,300 all entitled “MEDICATION INJECTION SITE AND DATA COLLECTION SYSTEM”.
