In the prior art, medication is distributed in containers such as plastic vials, bottles, and packets. These containers are potentially expensive to manufacture and also produce considerable waste. Further, in a hospital or nursing home, ambulatory care facility, outpatient facility environment, or in another patient care facility (collective referred to herein as a “patient care facility”), individual servings of tablet form medications are typically dropped into a plastic cup and the tablets are later consumed. Typically, a piece of paper containing information directed to the patient and the medication, for example in the form of a tablet, is included in the cup. After the medication is consumed, the piece of paper and/or label is placed in the patient's medical record chart at the hospital or other medical related facility.
Also in the prior art, a pharmacy associated with a patient care facility typically prepares medications for patients in blister pack form, for example, a one month supply. Typically during rounds, a nurse arrives at a patient room and ensures that the patient is present. The charts for the patient are referenced, and the medication and/or procedures for the patient are noted and prepared. Tablets are removed from the blister pack and put in a paper cup and administered to the patient.
Bar codes are typically printed on individual items and on containers enclosing a number of items. Bar codes contain information encoded in bars and spaces of various widths and arranged in predetermined patterns. When a bar code is scanned by a bar code reading device (e.g., a laser scanner), the bars and spaces are usually crossed by the scanning beam along a horizontal plane, or alternatively, rastered or scanned omni-directionally. Bar code technology, including printers, scanners and decoders encompass symbologies (i.e., bar code languages) to encode data that are optically read, thus producing machine-readable symbols that capture visual images of the symbologies and convert them to computer-compatible digital data. The size of a bar coded label is determined in part by the type of coding used, by the size of the individual bars and spaces, or on the data-matrix or the composite symbology. The amount of information encoded in a bar code is constrained by the size limitations of the bar code.
There are many different bar code symbologies. Each symbology has its own set of rules for character (e.g., letter, number, punctuation) encoding, error checking, printing, and decoding requirements. The various bar code symbologies differ in the ways they represent data and in the type of data they can encode. Some only encode numbers, others encode numbers, letters and a few punctuation characters, still others encode the 128-character and even 256-character ASCII character sets. The newest symbologies include options to encode multiple languages and allow user-defined encoding of special or additional data. These new symbologies even allow, through deliberate redundancies, reconstruction of data if the symbol is damaged.
The conventional bar code symbol is “one-dimensional,” i.e., bars and spaces extend only in a single direction. One-dimensional bar codes are limited in the amount of data that can be encoded therein. Increasingly, a need exists for bar codes to contain more information than conventional bar code symbols. In response to this need, reduced space symbology (RSS) and composite symbology (CS) bar codes have been developed. RSS bar codes are one-dimensional, extending in one direction. Several variants of RSS exist including stacked, limited and expanded which have, inter alia, the ability to encode additional data beyond a basic, short identifier that is usually printed with bar codes. The second symbology, CS, consists of a one-dimensional symbol paired with, and in some cases logically linked, to a two-dimensional symbol printed directly above it. The composite, two-dimensional symbol is known in the art as a PDF 417 symbol or a UCC/EAN-128 specific variant of MICRO PDF 417. MICRO PDF 417 is a version of PDF 417 which is designed for small item marking. Currently, RSS/CS bar codes are defined having a data capacity ranging from 56 characters to 2,361 characters. In time, the data capacity is likely to increase.
RSS/CS bar codes effectively replace the need for external computer databases to be referenced after a value, for example an UPC item number, is extracted from a one dimensional bar code. Prior to the development of RSS/CS bar codes, after a value was extracted from a single dimension bar code, data were referenced in computer database(s) to provide associated details with the extracted value. RSS/CS bar codes, in contrast, contain much of the associated data previously stored in a collateral database. The RSS/CS bar code is, essentially, a database itself.
The present invention provides a foldable and sealable packet comprising folding perforations imprinted on the packet to define locations for folding, a sealant for maintaining the shape of the packet after the packet is folded at the folding perforations and a bar code, such as a RSS/CS barcode, containing information directed to at least contents of the packet. After the packet is folded and partially sealed, the packet is formed to become a container to receive the contents.
Other features of the foldable and sealable packet include storing the medication in the packet, wherein the medication includes at least one of capsules, tablets, gelcaps, dissolving strips, and caplets. Further, the foldable and sealable packet comprises human readable information printed thereon.

The foldable and sealable packet also comprises a tear off perforation portion that enables the removal of individual foldable and sealable packets in a strip of foldable and sealable packets.
In one example, the foldable and sealable packet, is formed as blister packs, wherein the blister packs are formed with at least one of a paper and film portion having an ink layer disposed thereon, and wherein the ink layer is adapted to be removed by a laser. Further, the RSS/CS bar code is formed in the at least one of paper and film by the removal of the ink by the laser.
Further, the foldable and sealable packet are formed in a plurality of foldable and sealable packets, wherein the first packet comprises information regarding the remaining ones of the foldable and sealable packets in the strip.
Further, the foldable and sealable packet comprises a removable tab portion. The removable tab portion comprises a CS portion of a RSS/CS bar code, and a RSS portion of the RSS/CS barcode and the portion of the foldable and sealable packet is adjacent to the tab portion comprises an identical CS portion and a portion of the RSS portion. When removed, the removable tab comprises a complete copy of the RSS/CS barcode on the portion of the foldable and sealable packet adjacent to the tab portion.
Also, the foldable and sealable packet further comprises a at least partially transparent window that enables a person to see the contents of the foldable and sealable packet.
Additionally, the foldable and sealable packet, further comprising at least one shape printed on the foldable and sealable packet, wherein the shape represents information directed to at least one of the contents of the foldable and sealable packet and the person who receives the foldable and sealable packet. The at least one shape is formed as at least one of a polygon, a bar, and a circle.
The information represented by the shape regards at least one of dosage, frequency of use, time of day for ingestion and warnings directed to the contents of the foldable and sealable packet.

The step of distributing the medication further comprises reading a bar code image on a wrist band worn by the patient to extract wrist band information, reading a bar code image on the foldable and sealable packet to extract content information representing the contents of the foldable and sealable packet, comparing the wrist band information with the content information, and providing the patient with the foldable and sealable packet containing the medication after confirming the wrist band information corresponds with the content information.
Other features and benefits are provided below.
For the purposes of illustrating the invention, there is shown in the drawings a form which is presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown. The features and advantages of the present invention will become apparent from the following description of embodiments of the invention that refers to the accompanying drawings, in which:
The present invention is directed to a system and method for improving distribution of medication. In accordance therewith, the present invention provides for a plurality of computer-related hardware and software applications to receive and process information directed to distribution of medication. Further, the invention is directed to providing a sealable bar coded label that is folded and glued or otherwise formed such that the label itself becomes a container for one or more tablet form medications.
Referring to the drawings in which like reference designators refer to like elements there is shown in
In the preferred embodiment, information processor 12 and user terminal 14 are any devices that are capable of sending and receiving data across communication network 16, e.g., mainframe computers, mini computers, personal computers, laptop computers, personal digital assistants (PDA) and Internet access devices such as Web TV. In addition, user terminals 14 are preferably equipped with a web browser, such as MICROSOFT INTERNET EXPLORER, NETSCAPE NAVIGATOR and the like. Information processor 12 and user terminals 14 are coupled to communication network 16 using any known data communication networking technology.
Also shown in
In accordance with the present invention, printer 18 produces sealable individual bar coded packets 20 that are used for medications. As used herein, the term medications generally refers to medicine that can be consumed by a patient. For example, medications include tablets, capsules, caplets, gelcaps and other types of medicine that is consumed orally.
As shown in
The various components of information processor 12 need not be physically contained within the same chassis or even located in a single location. For example, storage device 30 may be located at a site which is remote from the remaining elements of information processor 12, and may even be connected to CPU 22 across communication network 16 via network interface 28. Information processor 12 include a memory equipped with sufficient storage to provide the necessary databases, forums, and other community services as well as acting as a web server for communicating hypertext markup language (HTML), Java applets, Active-X control programs and the like to user terminals 14. Information processor 12 are preferably arranged with components, for example, those shown in
As used herein, the term “link” refers to a selectable connection from one or more words, pictures or other information objects to others in which the selectable connection is presented within the web browser. The information object can include sound and/or motion video. Selection is typically made by “clicking” on the link using an input device such as a mouse, track ball, touch screen and the like. Of course, one of ordinary skill in the art will appreciate that any method by which an object presented on the screen can be selected is sufficient.
The functional elements shown in
Of course, one of ordinary skill in the art will understand that the capabilities of the functional elements can be adjusted as needed. The nature of the invention is such that one skilled in the art of writing computer executable code (i.e., software) can implement the described functions using one or more of a combination of popular computer programming languages and developing environments including, but not limited to C++, Visual Basic, Java, HTML and web application development applications.
It is contemplated that system 10 is arranged such that user terminals 14 communicate with and display data received from information processor 12 using any known communication and display method, for example, using a non-Internet-browser viewer coupled with a local area network protocol such as the Internet Packet Exchange (IPX), dial-up, third-party, private network or a value added network (VAN).
It is further contemplated that any suitable operating system can be used on information processor 12 and user terminal 14, for example, DOS, WINDOWS 3.x, WINDOWS 95, WINDOWS 98, WINDOWS NT, WINDOWS 2000, WINDOWS ME, WINDOWS CE, POCKET PC, WINDOWS XP, MAC OS, UNIX, LINUX, PALM OS and any other suitable operating system.
As used herein, references to displaying data on user terminal 14 refers to the process of communicating data to the terminal across communication network 16 and processing the data such that the data is viewed on the display 34, for example by using a web browser and the like. As is common with web browsing software, the display screen on user terminals 14 present sites within the system 10 such that a user can proceed from site to site within the system by selecting a desired link. Therefore, each user's experience with system 10 is based on the order with which they progress through the display screens. Graphic controls are preferably available in the display screens and modules to initiate data processes, and to provide convenient navigation between the display screens and modules of system 10. In other words, because the system is not completely hierarchical in its arrangement of display screens, users can proceed from area to area without the need to “backtrack” through a series of display screens. For that reason, and unless stated otherwise, the following discussion is not intended to represent any sequential operation steps, but rather to illustrate the components of system 10.
Form of Sealable Individual Bar Coded Labels
The sealable individual bar coded packet 20 may be available in a plurality of forms.
In another embodiment, shown in
In a preferred embodiment and as shown in
In yet another embodiment, a series of labels are formed on a conventional paper sheet which is fed into, for example, a laser, impact, or ink jet printer, the sheet preferably is provided with perforations and scores for separating the labels and enabling folding of the labels and subsequent gluing to form individual packets. The labels can be formed into different sizes and shapes, depending upon the quantity and size of a medication that is to be inserted therein.
The front card sheet 48 is also preferably punched with holes in a regular pattern of rows and columns to create a thirty, sixty or ninety hole count. A sheet of blisters that protrude through the card holes is preferably created from a vacuum formed sheet of thermoplastic.
In order to use the blister pack, the user punches the medication through the rear hole of the card stock 56, breaking the foil/paper 52 backing in the process. The plastic blister is preferably thin and flexible such to allow this movement.
The black ink layer 54 that is printed on the back of the foil/paper 52 is preferably burned away by the laser printing thereby leaving an RSS/CS bar code and a human readable portion in each cell unit.
Contents of Sealable Individual Bar Coded Labels
Preferably, and as shown in the example sealable individual bar coded packet of
Moreover and as shown in
In a further alternative embodiment, not shown, the labels at least in part comprise an at least partially transparent window that enables a person to see the contents of the sealable individual bar coded packet 20. This window enables a user to at least see the shape and color of the medication that is contained in the sealable individual bar coded packet 20.
The sealable individual bar coded packet 20 preferably includes an RSS/CS bar code that is printed thereon. That bar code preferably contains information directed to the patient and the medication. For example, patient demographics, patient medical history, allergies and the like are included in the bar code. Information directed to the medication, including batch and lot number, drug interactions, and information generated from a host of medical databases available over a global communication network may also be included. Furthermore, since the RSS/CS barcode can contain a relatively larger amount of information than other types of barcodes, the information in the RSS/CS bar code is preferably comprised of the GTIN, LOT EXPIRY DATE, concentration, and prescription record number of the medication and patient. Also printed on the sealable individual bar coded packet 20 there may be directions for use and intake in a human readable form for the benefit of the patient or the patient's care provider, including the time, date and other instructions regarding consumption of the medication.
Furthermore, a roll comprising a web of preprinted sealable individual bar coded packets 20 can be obtained by a party for filling prescriptions or supplying medications, and the roll is easily inserted in a printer and printed and/or folded and/or filled with medication at high speed (see
Furthermore, and as shown in
For example, a single bar that is longer than the width of the RSS/CS bar code printed on the label represents a dosage of 10 mg. of a specific medication, for example, ibuprofen. A similar bar that is printed on a different label, which has the same width as the RSS/CS bar code represents a different dosage, e.g., 25 mg. of ibuprofen. A single bar that is half of the width of the RSS/CS bar code represents 50 mg. of medication, and a bar that has a narrow width, for example, one quarter of the width of the RSS/CS bar code, represents a dosage of 100 mg. of ibuprofen. In the above examples, the single bar can be printed in conjunction with a number, for example, 10, 25, 50 and 100, respectively, to represent, for example, the varying dosages, time of day, etc. can be indicated too (see page 14).
The present invention also utilizes different shapes, for example, circles, squares or other polygons, to represent different kinds of information. For example, a small circle with an embedded number 5 represents, e.g., a dosage, quantity, day of the month, or other pertinent information that physicians, pharmacists, patients, or anyone else associated with the medication requires. The present invention further prints larger circles associated with different numbers to represent other information. For example, a slightly larger circle embedding the number 10, a larger circle with the number 15 embedded therein, and yet a larger circle having the number 20 embedded therein represent specific information directed to the medication, e.g., type of medication and a milligrams dosage level per tablet (see page 14).
Moreover, the imprints are not limited to circles or bars. A variety of polygons including six-sided, five-sided, four-sided and three-sided polygons, each having embedded numeral values therein can represent a plurality of information types, for example, medications, dosages, dates, floors in a hospital, etc. In this way, errors that can frequently occur, for example, due to illegible handwriting, are avoidable since a person using the present invention can easily view the label of the medicine and see a five sided polygon rather than a three-sided polygon, to avoid an error. For example, a three sided polygon may represent a weaker dosage than a six sided polygon. A nurse, or other healthcare provider, viewing the three-sided polygon can easily see that an incorrect dosage has been distributed for the patient.
A plurality of shapes on a single label may represent information directed to the medicine. For example, a single circle on a single label represents the first week of a month that a medicine is to be consumed, while three circles on a single label represent the third week of a month in which a medicine is to be consumed. Alternatively, the number of shapes on the label may be employed to indicate the number of dosages per day. In this way, errors that occur, for example, due to illegible handwriting, can be prevented by merely looking at a label and seeing an incorrect number of shapes on the label.
The use of bars and other shapes on labels has many applications in addition to labels for medicine. Any requirement for labeling information can utilize the system of graphic shapes as described herein. For example, labels directed to parts and components, tools, etc. all simplify and reduce errors by using the system shapes and/or numbers as directed by the present invention.
In accordance with the principles of the present invention, the employment of a plurality of shapes and numbers, for example, bars, circles and polygons, are printed on the sealable individual bar coded packet 20 to further provide information, for example, instructions and warnings, to the viewer of the label. The human readable markings are typically provided in addition to the bar coding. In a preferred embodiment, both the removable tab contains the shape and/or number, and the sealable individual bar coded packet 20 has the identical shape and/or number printed thereon. In this way, redundant information can be used for patient charts, or other information sources, with very little effort from a healthcare provider.
System and Use of Sealable Individual Bar Coded Labels
In accordance with the present invention, a plurality of hardware and software modules are integrated to produce the sealable individual bar coded packet. In the examples shown in
Preferably, instructions received from a physician are transmitted to a server system which processes the instructions and directs instructions to a printing device to produce the sealable, individual bar coded packets. In a preferred embodiment, a physician or care provider at the patient's location may use a portable device, for example, a personal digital assistant (PDA) as a user terminal 14 to input or receive information and instructions regarding the patient's medication into or from the portable device. Thereafter, information entered into the portable device may be transmitted to a receiving device, for example, into a personal computer via an infrared port, via a communication network. The information in the personal computer is transmitted to a server system and used to direct the printing of the sealable individual bar coded packet 20.
A plurality of databases that are presently available over the communication network may be accessed, and information that is relative to the specific patient and/or medication is electronically stored that may be retrieved and included for printing on the sealable, individual bar coded label 20. For example, batch and lot numbers directed to the medication, warnings regarding potential harmful combinations with other medications, drug recall information and the like may be retrieved from the plurality of databases. The information gathered from these plurality of sources are preferably compiled and printed on the label in at least one of human readable and machine readable form. Other information, for example, special orders that are received from the physician, is also preferably transmitted and printed on the sealable individual bar coded label.
Additionally, the one or more software modules causing the production of the sealable individual bar coded packets also transmit instructions to at least one printing device that causes the sealable individual bar coded packets to be printed in accordance with one or more rules. For example, a series of packets can be printed that are directed to a single patient. In this example, sealable, individual bar coded packets for an entire week's worth of medications are printed in a single print operation, the packets are filled with the appropriate medication, and the specific packets are delivered to the patient. Alternatively, the print operation is directed to print a plurality of sealable individual bar coded packets for a single medication. Further to this example, the same packet is produced a number of times, and a person simply tears off the sealable individual bar coded packet containing the medication and delivers the packet(s) containing the medication to an appropriate party.
After a physician or care provider prescribes medication for a patient, the information is transmitted to a server system and the server system or other computer system is directed to print the sealable individual bar coded packet 20, to dispense the medication into the packet, and then finally to seal the packet. In this way, little human intervention is required to fill a prescription.
During the step of dispensing the medication, a caregiver preferably uses a bar code reading device, such as a scanner, wand or other device, to read the contents of the patient's wrist band. Thereafter, the bar code printed on the sealable individual bar coded packet 20 is read, and a comparison occurs to ensure the caregiver is with the correct patient and the medication matches the physician instructions. Moreover, the patient record is electronically updated prior to the distribution of the sealable individual bar coded packets 20. A comparison is further made with the patient's record to ensure the medicine is correct. Furthermore, preferably, the caregiver visually inspects the sealable individual bar coded packet 20 to determine that the contents of the packet 20 match an image that is printed on the packet that represents the contents. After the electronic and visual confirmations are made, then the patient preferably receives the medication.
In one preferred embodiment, the patient is wearing a bar coded wristband. The blister pack cells, typically 30, 60 or 90 cells per blister pack, are individually bar coded and sequentially numbered. When the caregiver administers medications, all information is entered into an electronic monitoring database which records the patient wristband, date, time, medications, dosage and any other incidents that might occur during rounds.
The present invention has many advantages over the prior art. For example, the medications are sealed in inexpensive, disposable and/or recyclable packets. This eliminates the need to produce plastic vials which are more expensive and potentially harmful to the environment in production and later disposed. Moreover, no separate label application step is needed to place a label on a separate container, for example, a vial, thus saving operator time and eliminating a human step which has potential for error.
Additionally, multiple sealable individual bar coded packets 20 can be produced on a single sheet or web or roll, thereby increasing productivity and decreasing costs. Additionally, the many interfaces with which drug databases via a global communication network can be accessed increases the amount of information that can be integrated and presented to physicians and patients via the present invention. Properly marked, individually wrapped bar coded medications allow for the medication to remain hermetically sealed, and delivered via an automated healthcare delivery system which may include all of the checks and safeguards a computerized system may allow.
Other advantages of the present invention include efficiency, a decrease of errors caused by human intervention, decreased costs and increased efficiency.
Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. For example, the sealable individual bar coded packets 20 can be used for hardware, such as screws, nuts, bolts and the like. Further, small parts that are included with items that require some assembly can be stored in sealable individual bar coded packets 20.
Therefore the present invention is not limited by the specific disclosure herein.
