Description

FIELD OF THE INVENTION

This invention concerns a bar code generation and processing system for associating a bar code with a particular bar code scanner and a data destination associated with a particular executable application and communicating data acquired using the particular bar code scanner to the data destination.

BACKGROUND OF THE INVENTION

In known systems, a single barcode is typically directly associated with a barcode data receiving device to support an association between bar code and the device in a computer system, for example. Barcode readers are used with a medical device or other non-PC systems that incorporate embedded software. In industry and healthcare settings, barcode readers are used to capture information from a bar code label and insert it into a software system. This is usually done by using a barcode reader which is connected to a computer system or device. In this case, the data is read from a paper printed barcode label and inserted into an appropriate data field in storage in a system to which the barcode reader is attached.

In known systems a barcode reader typically needs to be physically connected to the system receiving the barcode data. If a wireless barcode reader is deployed, the barcode reader is still required to be matched with a specific device and the device is required to support a driver or connection option for a barcode reader (Serial, USB, or keyboard). In known systems that use a Bluetooth wireless barcode reader, for example, a user needs to use the barcode to scan a particular PC with which to setup a Bluetooth connection. The barcode reader is then associated to that PC. A system according to invention principles addresses these deficiencies and related problems.

SUMMARY OF THE INVENTION

A system enables wireless barcode readers to be used in a processing environment including different devices and different software applications by dynamic assignment of a barcode reader device to a software application using a barcode system server and “association” barcodes including both physical barcodes and dynamically created on-screen software generated barcodes. A bar code generation and processing system for medical and other use comprises at least one repository and a bar code processor. The at least one repository of information includes, identification data of multiple bar code scanners and also associates a bar code displayed in an image associated with an executable application and presented on a device with, the executable application and at least one of, (a) the device and (b) a data destination associated with the application. The bar code processor receives identification data of a bar code scanner and data representing the bar code displayed in the image and uses the information in associating the bar code with the data destination associated with the application and a particular bar code scanner of the multiple bar code scanners. The bar code processor communicates data acquired using the particular bar code scanner to the data destination in response to the association.

DETAILED DESCRIPTION OF THE INVENTION

A system enables wireless barcode readers to be used throughout a software system and on different devices using different software applications by dynamic assignment of a barcode reader device to a software application and elements of the application as well as to associated tasks and processes. The system utilizes a barcode system server and “association” barcodes which might include both physical barcodes and dynamically created on-screen software generated barcodes.

The system enables multiple barcode readers to be deployed throughout an organization. The devices receiving the barcode data are not required to support barcode readers with particular types of driver or connection. This means existing devices may employ firmware modified according to invention principles to take advantage of the barcode system without requiring new hardware or hardware modifications. Also the system enables provision of a barcode reader association for a specific software application or image, not just an entire processing device or PC, for example. Specifically, the system advantageously enables association of a barcode reader with a specific software application, image, or text field allowing greater flexibility than associating the reader to a complete processing device.

FIG. 1 shows bar code generation and processing system 10 for medical and other use. System 10 includes one or more processing devices on network 21 (e.g., medical device, infusion pump, workstation, computer or portable devices such as notebooks, Personal Digital Assistants, phones) 12 that individually include a user interface enabling user interaction with a Graphical User Interface (GUI) and display 14 supporting GUI and executable application display image presentation. Processing device 12 executes Application 34 and includes communication processor 16 and the display 14. System 10 also includes bar code scanners 26 including scanners 41 and 42 in wired or wireless communication with server 30 via network 21 or another communication link. Bar code server (processor) 30 includes at least one repository 17, a general system settings function 23 and interface 19 to executable applications (e.g. Application 34).

At least one repository 17 includes identification data of multiple bar code scanners 26 and includes information associating a bar code displayed in an image with executable application 34 and with at least one of, (a) device 12 and (b) a data destination associated with Application 34. The image is associated with Application 34 and is presented on device 12. Bar code processor (server) 30, receives identification data of bar code scanner 41 and data representing the bar code displayed in the image and uses the information in associating the bar code with the data destination associated with application 34 and particular bar code scanner 41 of multiple bar code scanners 26. Bar code processor 30 communicates data acquired using the particular bar code scanner to the data destination in response to the association. Wireless barcode readers 26 operate over a standard wireless network in an enterprise such as a hospital. Processor 30 manages unique onscreen association barcodes and uses repository 17 in tracking mapping between currently associated barcode reader devices and active software sessions. Processor 30 enables addition of wireless barcode readers to the system and change of system configuration. Interface 19 provides an interface that operates over different types of network to send and receive information to software applications which use the barcode system.

Display 14 on device 12 presents an image associated with executable application 34 including a bar code. Communication processor 16 communicates a request for the bar code to a remote system (server 30). Communication processor 16 receives data representing the bar code for presentation in the image from the remote server system 30 in response to the request. The bar code is associated in at least one repository 17 of information, with a data destination associated with application 34 and particular bar code seamier 41 of multiple bar code scanners 26. Processor 16 receives data acquired using particular bar code scanner 41 for incorporation in the data destination in response to bar code scanning of an item with particular bar code scanner 41. Application 34 employs communication processor 16 in requesting from processor 30 unique bar codes associated with data destinations of application 34 and in receiving the barcode data.

System 10 uses barcode reader server 30 to send barcode data to a receiving system or device, such as device 12. An environment has n wireless barcode readers 26 which transmit their data to receiving server 30. Barcodes are generated and presented in an image provided by Application 34 (for example, on a patient header in a healthcare related system). The software generated onscreen barcodes are unique. When a user is ready to scan barcode data for a software application on a terminal or device, the user first scans the barcode on the screen of device 12. This unique barcode is recognized by barcode server 30 as representing a particular instance of a software application user interface image (by a specific session identifier of a webpage, by an identifier associated with the image or by another unique method of recognizing the specific image of images provided by multiple software applications). Data scanned by a barcode reader is transmitted to a software application 34 image to which the reader has been associated. Subsequently, if the image changes, the onscreen barcode is changed or is removed (and the association is discarded). In this case, system 10 requires a changed bar code to be rescanned to re-associate the barcode reader with application 34. A barcode which is scanned by the reader, while the reader is in an unassociated state, is ignored.

A healthcare or other hospital information system using Application 34 employing the barcode system uses a bidirectional interface with the barcode system for transmitting a unique one time barcode being used in an assigned location in an application image or workflow. In addition to transmitting the barcodes which are being displayed, Application 34 transmits to barcode server 30 a location ID (Session ID or other unique identifier) identifying where that unique barcode is being used. Application 34 has a receiving interface for receiving barcode data from the barcode server. This is data which starts with an association barcode and is followed by barcode data. When an association barcode is received by a receiving system, the subsequent associated barcode data is used in the context of the application workflow to which the association barcode belongs.

FIG. 2 shows a flowchart of a process for generating and processing bar code data. In one embodiment, following the start at step 203, Application 34 that is modified to acquire data from bar code processor 30 in step 206, employs lookup table 400 of FIG. 4 for associating a unique location, task or process type of associated executable Application 34 with a bar code scanner 41 acquired bar code data item. Table 400 of FIG. 4 shows a lookup Table linking a unique location identifier, task identifier or process identifier (ULID) (column 403) with unique location, task or process type (column 405) of an associated executable application and with a description (column 407). A unique location associated with an executable application may comprise, a displayed data field, text field, single display image, displayed button or displayed option list item or a memory location (not shown in Table 400), for example. A unique task associated with an executable application and having a task identifier, may comprise an individual workflow task performed by a user or processing device. A unique workflow process, or executable process associated with an executable application and having a process identifier, may comprise an individual workflow process performed by a user or processing device.

FIG. 6 shows display image 603 associated with barcode 607 presented in an Application 34 operation session and the system employs a barcode associated with particular text data field 605 in image 603. In one embodiment, image 603 uses a barcode for a whole computer operation or application operation session and in another embodiment uses a barcode associated with a particular text data field that is not associated with a complete operation session. Application 34 in step 209 (FIG. 2), employs lookup table 400 of FIG. 4 for associating a unique location, task or process type of associated executable Application 34 with a bar code scanner 41 acquired bar code data item. Specifically, Application 34 associates a unique location, drug name text data field 605 associated with executable Application 34 with a bar code scanner 41 acquired bar code data item. In step 211 Application 34 sends a particular unique location identifier (ULID) derived from Table 400 and assigned to text data field 605 to server 30 in a request for display of a bar code associated with data field 605. In step 214 Application 34 receives the requested bar code associated with data field 605 and in step 217 displays the bar code in data field 605 in image 603.

Application 34 in step 220 listens for data from server 30 that is tagged with the particular ULID and in response to receiving data representing a drug name, for example, populates data field 605 of image 603 with the drug name in step 223 and uses the drug name in an associated drug administration workflow. In step 225 Application 34 after a predetermined timeout period actively discards the particular ULID being used and disassociates the particular ULID from data field 605. In step 227 Application 34 sends a message to server 30 to initiate discarding the association of the particular ULID with data field 605. The text data field 605 association is used and inactivated substantially when the data barcode is scanned and populated in text data field 605 as shown in FIG. 7. Specifically, FIG. 7 shows display image 603 associated with Application 34 having particular text data field 605 associated and populated with particular barcodes. The barcode system is also usable in embedded systems and in one embodiment a firmware upgrade enables use of the barcode system with a device in associated relevant workflows.

FIG. 8 shows display image 803 associated with a particular application and infusion pump device having a bar code 805 associated with particular text data field and infusion pump data item. In this example, the bar code system is used with an embedded device, an infusion pump. An infusion pump may employ firmware for controlling pump settings and other operational parameters of a device. The pump may also communicate with a pump server which monitors and communicates with multiple pumps. Modified pump firmware displays a barcode in an image on a pump display screen. The barcode is unique and generated by the system for one time use. A clinician, in response to connecting a pump to a patient scans the barcode on the image of the pump (the association barcode) presented on a pump display and scans the barcode on the wristband of the patient (the data barcode). Upon receiving both the association barcode and data barcode scans, the barcode server transmits to the pump gateway, information about the scan. The pump gateway is programmed to send the patient ID information to the pump and set that information in the pump memory. Future data from the pump is transmitted tagged with the correct patient identification information. FIG. 9 shows a display of patient monitoring data of a particular patient associated with a patient monitoring device via a bar code association made using a bar code displayed on an image on the patient monitoring device.

FIG. 3 shows a flowchart of a process for processing bar code data by remote processor (server) 30 (FIG. 1). In one embodiment, following the start at step 303, processor 30 interface 19 in step 306 receives a particular unique location identifier (ULID) from Application 34. In step 309, processor 30 generates a unique bar code or retrieves the unique bar code from storage and sends the unique bar code associated with the received ULID to Application 34 via interface 19. Processor 30 in step 311 stores the received ULID in table 500 of FIG. 5 in association with the generated or predetermined associated barcode. Table 5 (FIG. 5) links the received unique location identifier, task identifier or process identifier (ULID) (stored in column 503), with unique location, task or process type (column 505) of an associated executable application, the generated or predetermined associated bar code (column 507) sent to Application 34, bar code scanner identifier (column 509) and with an identifier of the executable application (Application 34, column 511).

In step 314, in response to scanner 41 scanning the unique bar code associated with the received ULID sent to Application 34 and displayed in text field 605 (FIG. 6), for example, scanner 41 is associated with the scanned unique bar code by storage of a scanner 41 identifier in Table 500. Scanner 41 is used in step 317, to scan an item of data e.g. a patient name in a wrist band bar code and in step 320 processor 30 sends the patient name to an Application (Application 34) associated with the ULID of the location associated with the unique bar code. In step 323, processor 30 receives a message commanding processor 30 to discard the association of the unique bar code and with the ULID. In one embodiment this message is generated in response to elapse of a timeout period, in another embodiment the message is generated in response to a command by Application 34. Processor 30 in step 325 updates Tables 400 and 500 to remove the association of the unique bar code with the ULID.

FIG. 10 shows a flowchart of a process employed by a bar code processing system e.g. processor 30 (FIG. 1) for processing bar code (e.g. bar code or a QR (quick response) code) data. Processor 30 in step 752 following the start at step 751, stores in at least one repository 17, information including, identification data of multiple bar code (e.g. wireless) scanners and also data associating a bar code displayed in an image associated with an executable application and presented on a device with, the executable application and at least one of, (a) the device and (b) a data destination (e.g. a data field in a displayed image) associated with the application. In one embodiment, the device is an infusion pump and processor 30 uses the information in associating the bar code with the infusion pump. In another embodiment, the device is an electronic device with a graphical user interface, and processor 30 uses the information in associating the bar code with the electronic device.

The information associates the bar code displayed in the image with elements including, at least one of, (a) a text field, (b) a workflow process, (c) a task identifier of a workflow process, (d) an image associated with the application, (e) a selectable button in the image associated with the application and (f) a value to be entered in an option list in the image associated with the application. Processor 30 uses the information in associating the bar code with at least one of the elements. In step 755, processor 30 receives identification data of a bar code scanner and data representing the bar code displayed in the image and uses the information in associating the bar code with the data destination associated with the application and a particular bar code scanner of the multiple bar code scanners. In one embodiment a bar code scanner is a phone, computer or watch, for example.

Processor 30 in step 758, communicates data acquired using the particular bar code scanner to the data destination in response to the association. Processor 30, receives identification data of a first bar code scanner and data representing the bar code displayed in the image and identification data of a second bar code scanner and data representing the second bar code displayed in the image (or a second image). Processor 30 uses the information in associating the first bar code with a first data destination associated with the application and the first bar code scanner of the multiple bar code scanners and in associating the second bar code with a second data destination associated with the application and the second bar code scanner. Also processor 30 communicates data acquired using the first and second bar code scanners to the respective first and second data destinations in response to the association. In one embodiment, processor 30 dynamically generates the bar code displayed in the image and the bar code is acquired by the application. In step 760, processor 30 discards the association with the dynamically generated bar code displayed in response to completion of use of the bar code. Alternatively, processor 30 discards the association in response detection of completion of a workflow task. The process of FIG. 10 terminates at step 763.

FIG. 11 shows a flowchart of a process employed by a bar code processing Application e.g. Application 34 (FIG. 1) for processing bar code data. Application 34 in step 772 following the start at step 711, displays an image associated with executable Application 34 and the image includes a bar code. In one embodiment, Application 34 operates on a computer in a medical device and the display resides on the medical device (e.g., an infusion pump). In step 775, Application 34 communicates a request for the bar code to a remote system (processor 30). In one embodiment Application 34 includes a communication processor and is within a computer provided on a mobile unit for use in patient rooms in a hospital. Application 34 in step 778, receives data representing the bar code for presentation in the image from the remote system in response to the request. The bar code is associated in at least one repository of information, with a data destination associated with the application and a particular bar code scanner of multiple bar code scanners. The at least on repository of information is within the computer or within the remote system. In step 780, Application 34 receives data acquired using the particular bar code scanner for incorporation in the data destination in response to bar code scanning of an item with the particular bar code scanner. The process of FIG. 11 terminates at step 783.
