Patent Application
20220093243
The present invention relates to systems for controlling, managing and enhancing operation of devices. It relates particularly, but not exclusively, to systems that are operable with mobile and other computerised devices, to access data and control signals from laboratory devices namely, instrumentation and related devices used in the processing of tissue and other specimens for pathology testing and the like.
Laboratory instruments are used to perform specimen processing, typically for diagnostic purposes. They are often high cost instruments using high value reagents and other consumables. The tests that they perform often can be critically important in the diagnosis and effective treatment of disease and disorders, but they are often expensive. Errors in processing, delays and instrument down time can add to the cost of operating laboratories in which these instruments are used.
Most modern laboratory instruments are automated in some way and computer control is becoming commonplace. Nevertheless, each instrument may have a unique operating system and use different data schema and control signals. This is beneficial in that advancement is not limited by a requirement to adhere to standards that may be outdated. However, it inhibits integrated management of multiple instruments. This problem is exacerbated in laboratories containing instruments from different manufacturers and of significantly different age.
It would be desirable to provide a platform or system that permits integrated and streamlined management of multiple instruments in a laboratory. It would also be desirable to provide a system that provides users with customised interaction with an instrument in a laboratory.
The discussion of the background to the invention included herein including reference to documents, acts, materials, devices, articles and the like is included to explain the context of the present invention. This is not to be taken as an admission or a suggestion that any of the material referred to was published, known or part of the common general knowledge in Australia or in any other country as at the priority date of any of the claims.
Viewed from one aspect, the present invention provides a system for customising management of one or more instruments in a laboratory, the system including: a user device adapted to receive inputs from a user, the user device having a device processor for processing the received inputs and instrument data from the one or more instruments, and a device display for displaying instrument information; an interface module communicatively coupled with the user device and the one or more instruments and configured to convert instrument data in a first format generated by an instrument processor to a second format for processing by the device processor; and an instrument module configured to cause the device processor to provide customised instrument information on the device display.
Preferably, the user device is configurable with an instrument module by: a user requesting application software corresponding to the instrument module from a remotely located vendor; the vendor approving the request and operating a distribution software program to deliver the requested application software to the user device; and the user installing the application software on the user device to activate the instrument module. Typically this is enabled in a cloud computing environment.
Preferably, the instrument module is selectable from a suite of instrument modules with which the user device may be configured including, but not limited to: an inventory management module; an instrument management module; a statistics module; a workflow module; a maintenance module; and a reporting module.
An inventory management module may be configurable for customised inventory management by performing functions on the device processor selected from the group including: interrogating for and/or receiving automatically from one or more instruments inventory levels for individual ones of the instruments; interrogating for and/or receiving automatically from instruments in the laboratory aggregated inventory levels across a plurality of instruments in the laboratory; interrogating for and/or receiving automatically from one or more instruments in the laboratory an estimated time at which supply of a consumable in the laboratory will be critically low; automatic ordering of one or more consumables used by an instrument in the laboratory; tracking an order status for consumables ordered by the inventory management module; presenting on the device display inventory management information; and automatically invoicing an entity for consumables ordered by the inventory management module.
Additionally, the inventory management module may be configurable to determine automatically when the user device is in close physical proximity to an instrument in the laboratory that has an inventory management issue and automatically issue a notification to the user device advising the operator to perform an inventory management operation on the instrument.
An instrument management module is configurable for customised instrument management by performing functions on the device processor selected from the group including: interrogating for and/or receiving automatically instrument status information from one or more instruments and presenting on the device display status information for the one or more instruments; interrogating for and/or receiving automatically alert data from one or more instruments and presenting on the device display an alert symbol or notification, for respective ones of the instruments; interrogating for and/or receiving automatically an urgent specimen signal and presenting on the device display an urgency symbol or notification for one or more of the instruments associated with the urgent specimen signal; receiving from the user customisation rules, and customising the instrument management module according to the customisation rules. Typically, the instrument status is represented by an icon.
The customisation rules may include e.g. user-defined instrument naming, user-defined instrument positioning on the display, user-defined instrument parameters for presentation on the display and user-defined instrument control features controllable by the user device using the instrument management module to name a few.
A workflow module may be configurable for customised management of specimen processing steps performed by one or more instruments in the laboratory, by performing functions on the device processor selected from the group including: receiving electronically a request for a specimen processing step not already scheduled on an instrument and causing scheduling of the requested processing step on an instrument. Ideally, the scheduling performed by the workflow module optimises use of instruments, and timing of processing steps, across instruments in the laboratory. The workflow module may include further functions such as receiving specimen data from one or more instruments and presenting on the device display a related image or result of a processing step; processing specimen data received from one or more instruments and automatically presenting on the device display a recommended action; receiving specimen processing schedules from a plurality of instruments and automatically re-scheduling one or more processing steps to optimise one or more constraints selected from the group including scheduled completion time, consumables used, operational cost, staffing requirements and specimen processing value; and presenting current status information for specimen processing steps.
A maintenance module may be configurable for customised instrument maintenance by performing functions on the device processor selected from the group including: interrogating for and/or receiving automatically maintenance data from one or more instruments in the laboratory and causing the user device to display a prompt when ones of the instruments have a scheduled maintenance event; interrogating and/or receiving automatically aggregated maintenance data from a plurality of laboratories and adjusting a scheduled maintenance event based on the aggregated data; aggregating scheduled maintenance events for a plurality of instruments in the laboratory and creating new maintenance schedule which optimises one or more constraints selected from the group including scheduled instrument downtime, technician availability, and impact on scheduled or expected specimen processing; and transmitting to a remote processing device maintenance data from the one or more instruments for aggregation with maintenance data from one or more other laboratories.
A reporting module may be configurable for customised reporting of instrument related performance data, by performing functions on the device processor selected from the group including: receiving operator defined specifications for data analysis; receiving operator defined specifications for data reporting; aggregating instrument performance data for a plurality of instruments in the laboratory and presenting on the device display laboratory performance information based on the aggregated instrument performance data; and transmitting to a remote processing device instrument and/or laboratory specific performance data for aggregation with performance data from one or more other laboratories.
The user device may be a handheld device such as a smart phone or tablet computer although a notebook computer, netbook computer, body-worn computer (including devices such as Google™ glasses, smartwatches, virtual reality goggles and the like or various other mobile computing devices are contemplated. Non-mobile computing devices may also be suitable for achieving user device functionality.
In some embodiments, the instrument module is configurable to determine automatically when the user device is in close physical proximity to an instrument in the laboratory; and automatically issue a notification to the user device which is relevant to an instrument in close proximity. Similarly, the instrument module may be configurable in accordance with customisation rules received from the user as inputs to the user device, to customise the user's interaction with instruments through the user device.
Viewed from another aspect, the present invention provides a method of deploying a platform for integrated management of instruments in a laboratory, the platform including one or more instrument modules deployable to user devices operated by users, the method including the steps of: a user operating a user device to request application software corresponding to an instrument module from a remotely located vendor; the vendor approving the request and operating a distribution software program to deliver the requested application software to the user device; and installing the application software on the user device to activate the requested instrument module.
Typically, after approval of a first request associated with a laboratory, the method includes causing installation of an interface module in the laboratory to permit transmission of laboratory instrument information from the instruments to the user device.
The present invention will now be described in greater detail with reference to the accompanying drawings. It is to be understood that the embodiments shown are examples only and are not to be taken as limiting the scope of the invention as defined in the claims appended hereto.
Where the terms “comprise”, “comprises”, “comprised” or “comprising” are used in this specification (including the claims) they are to be interpreted as specifying the presence of the stated features, integers, steps or components, but not precluding the presence of one or more other features, integers, steps or components or group thereof.
Referring firstly to
A user 1100 may interact with instruments 1500 by controlling a user device 1200 as required. Typically, the user device 1200 is a handheld or mobile computing device such as a smartphone, tablet or laptop computer, desktop computer or the like although it is to be understood that the functionality of user device 1200 may be incorporated into any suitable appliance capable of at least the user device functionality as described herein. For simplicity, such devices are referred to generically as “user device” 1200.
A schematic illustration of components of a typical user device 1200 is shown in
System 1000 has an interface module 2700 which is communicatively coupled (through a communications infrastructure such as the internet, Wi-Fi or other communication network, Bluetooth, RFID, cellular and others) with user device 1200 and the one or more instruments 1500. Typically, the interface module 2700 is provided on a secure computing device 1300 located in the laboratory. Alternatively, the functionality of interface module 2700 may be incorporated into a remote processor located “in the cloud” (as shown in
The first data format 1590 produced by instruments 1500 may be of a schema or type which is common to all instruments in the laboratory (but not common to user device 1200) although that may not always be the case. The format of the instrument data may depend on the make, model, age and/or type of instrument. However the interface module 2700 is configurable to receive instrument data 1590 in the format it is created by the instrument, and convert it to a second format 1290 which is receivable and understood by an instrument module 2000 installed on the user device 1200. In another embodiment, the functionality of interface module 2700 may be brought into effect in software operating on one or more of the instruments 1500 and/or on the user device 1200 adapted to receive instrument data in a first format 1590 and convert and transmit instrument data in a second format 1290, via a communications infrastructure, to one or more user devices 1200.
An advantage of embodying interface module 2700 on secure computing device 1300 located in a laboratory, is that critical instrument data conversions are secure. Additional functionality relating to patient data security may also be incorporated into the secure computing device 1300 which may further be configured to encrypt patient data for transmission to the user device 1200 for use by particular instrument modules 2000.
System 1000 includes an instrument module 2000 which causes the device processor 1210 to provide, among other things, customised instrument information on the device display 1220. In
In one embodiment, to obtain access to an instrument module, a user 1100 instigates a process of selecting and purchasing application software for installation on user device 1200. This is similar to purchasing an “app” from online marketplaces such as Google Play Store, Apple App Store and Windows Phone Marketplace, to install functionality on an Android phone or tablet, iPhone or iPad, Windows phone or tablet, a body wearable device including computer glasses, virtual reality headset, or similar device.
In embodiments of the present invention, a user 1100 requests application software 1400 corresponding to an instrument module 2000 from a remotely located vendor 1600. In one embodiment, vendor 1600 approves the request and operates a distribution software program (akin to those used by online market places as referred to above) to deliver the requested application software 1400 to the user device 1200. Approval may be contingent upon the user fulfilling an event, for example making payment or entering into some other arrangement with vendor, for the requested instrument module 2000. User 1100 installs the application software 1400 on the user device 1200 to activate the instrument module 2000. In another embodiment, user 1100 can download the application software 1400 corresponding to an instrument module 2000 without prior approval of the request from the vendor 1600. However, the application software 1400 will remain inactive until such time that vendor approval is sought and obtained by the user 1100.
Typically, the process also includes, at least for an initial instrument module purchase for access to an instrument 1500 in a laboratory, the vendor instigating a process for shipment of an interface module 2700 to the laboratory and arranging for a service technician to install the interface module in the laboratory. Alternatively, the system may be provided as a plug and play system, or a combination of plug and play and service technician installation. Installation may be in relation to a hardware or a software version of the interface module 2700 which, once installed, provides the necessary interface and data conversion functionality between instruments 1500 and user device 1200. In some embodiments, a laboratory may authorise access by more than one user device 1200, to instruments 1500 using the interface module 2700. Typically, each user 1100 of a device 1200 requests and installs application software 1400 for the installation of an instrument module on that device although it is to be understood that some devices may be sold or offered to some users with one or more instrument modules pre-installed.
Various instrument modules according to embodiments of the present invention will now be described. These may include, by way of example, an inventory management module 2100, an instrument management module 2200, a statistics module 2300, a workflow module 2400, a maintenance module 2500 and a reporting module 2600. Other examples of instrument modules that may be installed on the display device include but are not limited to:
An inventory management module 2100 is configurable for customised management of inventory such as reagents and other consumables (such as covertiles and coverslips) used by instruments in the laboratory.
An example of a Home screen 2122 for an inventory management module 2100 according to an embodiment of the present invention is presented in
A ‘cart’ screen (not shown) may be viewed by selecting Cart icon 2116. When the order is finalised, a product order is transmitted, by inventory management module 2100, from user device 1200 to the product supplier. The order can be tracked by selecting Order Status tab 2115.
Selection of tab 2124 presents a list of consumables that require refilling (i.e. are empty) or have expired (past their useful date). Selection of tab 2125 presents a watchlist of products that the user wishes to track. The watchlist may be configured by the user and/or populated automatically, at least in part. For example, when the user orders a product that is ‘out of stock’ with the supplier, that product is automatically added to the watchlist. The watchlist may also be viewed by selecting Watchlist icon 2112 in menu zone 2110.
Also in menu zone 2110 is any inventory item, reagent or consumable that is automatically tracked by a connected instrument, for example, the RTU icon 2113 which takes the user to a filtered view of RTU reagent status only. Inventory items, reagents or consumables include items such as covertiles, coverslips, cleaning kits, detection systems and theranostic devices (e.g. Leica BOND Oracle). Use of covertiles may be tracked using a usage chip applied to the covertile. Reagents are tracked by a unique product identifier. A Reagents & Consumables icon 2114 takes the user to a filtered view of non-RTU consumables and reagents status only including anything that is not automatically tracked such as individual items in boxes of gloves, boxes of slide, tubes, and the like which are tracked at supply order level rather that individual item. An Order Status icon 2115 takes the user to a screen where the user can view the status of orders placed through the inventory management module (or using other ordering processes). The Order Status screen may be embodied in a number of different formats, where orders may be viewed at the aggregate level, or at the individual product level.
An example of an Order Status screen 2132 for an inventory management module 2100 according to an embodiment of the present invention is presented in
Information presented to user 1100 by inventory management module 2100 is obtained by the module causing the device processor 1210 communicate with one or more instruments 1500 in the laboratory to receive or interrogate for inventory data for individual instruments, or for a plurality of instruments in the laboratory. This enables inventory management module 2100 to ascertain aggregated inventory levels across a plurality of instruments and, in preferred embodiments, to estimate based on current inventory levels and specimen processing steps scheduled to be performed by the one or more instruments, a time at which supply of a consumable will become critically low or exhausted. This may be communicated to user 1100 by symbols 2127 and 2129. Alternatively/additionally ‘push’ communication can be created by the inventory management module 2100 and delivered to the device display 1220 to alert the user 1100 that there is a critically low level of a particular consumable and prompting the user to take appropriate action such as attending the laboratory to refill or re-stock an instrument or reschedule one or more tests to avoid instrument downtime.
Ordering of one or more consumables for which there is no/low stock may be automated by inventory management module 2100, based on user-configurable ordering rules. Optionally, the rules may include prior finance approval from an account manager for a supplier of products used by the instruments, in which case invoicing to the laboratory may be automated.
In a preferred embodiment, inventory management module 2100 utilises a location service, such as a geolocation based on a WiFi connection, GPS, or assisted GPS (cellular location system) module 1230 in the user device 1200 to determine automatically when the user device 1200 is in close physical proximity to an instrument 1500 in the laboratory that has an inventory management issue (e.g. low/no stock) and to issue automatically a ‘push’ notification to the device display 1220 advising the operator to perform an inventory management operation (such as re-filling/restocking a reagent on board an instrument) while they are conveniently close to the problematic instrument.
Preferably, user 1100 can set rules for push communications which need not be limited to proximity to an instrument 1500. Push notifications may also be permitted e.g. to communicate when a reagent has reached a critically low level and/or to communicate how many tests may be performed based on current inventory, and suggesting that the user place an order through the inventory management module 2100. Push notifications may also be used to communicate order status information to a user. Although referred to herein as a ‘push’ notification, it is to be understood that such notifications may be by way of a message on device display 1220, and/or SMS and/or email or using a range of other communications platforms with which the inventory management module 2100 may integrate.
An instrument management module 2200 is configurable for customised management of one or more instruments 1500 in a laboratory.
Instrument management module 2200 may be configured to interrogate instruments for and/or receive automatically, status information, alert data, urgent specimen signals and the like. Module 2200 may also receive from user 1100 customisation rules for one or more of the instruments, for customisation of the instrument management module. The customisation rules may include but are not limited to user-defined instrument naming, user-defined instrument positioning on the device display, user-defined instrument parameters for presentation on the device display, and user-defined instrument control features.
Statistics module 2300 may be configured to calculate and display statistics pertaining to usage of instruments 1500 in the laboratory. Statistics may be user-definable, or there may be a standard statistics suite in the module. The statistics module provides an overview to a user based on summary statistics of variables and data collected by the laboratory instruments as part of a usual archiving process. Sample case statistics are shown in
Menu zone 2310 provides other options for viewing performance statistics relating to e.g. cases processed in a particular month, cases processed for a particular panel, (e.g. an antibody panel, a diagnostic panel, a breast cancer, or the like), cases processed for a particular pathologist, cases performed by a particular operator, for example a histotechnologist and a workload/predictor tool for projecting the number of cases likely to be processed in a particular future time period, based on current orders and/or historical statistics. This can be utilised by user 1100 (who may be e.g. a laboratory manager) to inform workforce management decisions and ensure adequate staffing (whilst minimising overstaffing) for operation of instruments 1500. The user may customise the statistical reporting by electing and modifying preferences.
A workflow module 2400 may be configured for customised management of specimen processing steps performed by one or more instruments in the laboratory. One feature of workflow module 2400 is a facility to receive, via a communications infrastructure, test orders placed by one or more pathologists who have sent a specimen to the laboratory for testing. The test request may be received using a schema that is automatically scheduled into an appropriate instrument 1500 by the workflow module e.g. where the pathologist has access to a “test request” via an online portal that uploads the request to the system 1000 via a communication infrastructure. Alternatively, the pathologist may request tests using electronic forms such as SMS, email, web-based form or the like that are automatically uploaded to the workflow module 2400 for manual scheduling by the user 1100. The workflow module 2400 also presents current status information for specimen processing steps requested using the workflow module.
The workflow module 2400 may also be configured to receive data pertaining to a specimen already processed on one of the instruments 1500 and automatically present to user 1200 a notification that results are available. Optionally, an image of the specimen or the results themselves, may be presented on device display 1220. In some embodiments, workflow module 2400 is configured to receive specimen data from one or more instruments 1500 and automatically present on the device display 1220 a recommended action (e.g. for further processing, an additional protocol, troubleshooting, suggestion to refer to website or information portal or the like). In some embodiments, workflow module 2400 is configured to receive specimen processing schedules from a plurality of instruments 1500 in the laboratory and automatically re-schedule one or more processing steps for one or more of the instruments to optimise one or more constraints. The constraints may include, but are not limited to, one or more of scheduled completion time, amount of consumables used, operational costs, staffing requirements and specimen processing value to the laboratory (e.g. financial versus reputational).
A maintenance module 2500 is configured for customised instrument maintenance functions and reporting. This may include interrogating and/or receiving automatically maintenance data from one or more instruments 1500 in the laboratory and prompting a user 1100 by notification or a message on device display 1220 when ones of the instruments have a scheduled maintenance event due or approaching. A calendar feature may present visually when ones of the instruments are due for a service call or maintenance event and the user 1100 may request re-scheduling by the maintenance module to avoid or minimise instrument downtime and/or scheduling conflicts e.g. with urgent slide processing requests. Thus, maintenance module 2500 may be configured to interrogate for, receive or generate aggregated maintenance data from a plurality of laboratories, and revise a scheduled maintenance event based on the aggregated data or create a new maintenance schedule which optimises one or more constraints that may include e.g. scheduled instrument downtime, technician availability, impact on scheduled or expected specimen processing and the like.
A reporting module 2600 may be configured for customised reporting of instrument related performance data. This may include receiving at the user device 1200 user-defined specifications for data analysis and/or reporting. Reporting module 2600 may aggregate instrument performance data for a plurality of instruments 1500 in the laboratory and present on the device display 1200 laboratory performance information based on the aggregated instrument performance data. Reporting module 2600 may also cause transmission of laboratory and/or instrument specific performance data to a third party 1650 for aggregation with corresponding data from one or more other laboratories.
Aggregation of data by a third party 1650 can relate to any data that is collected or created by the instrument module 2000, or by instrument processors 1510. Aggregated data may be used to monitor across multiple sites (and multiple laboratories, potentially in multiple countries): laboratory performance and patterns in instrument usage, consumption of reagent and other consumables, popularity of tests, common maintenance issues and other information that may be useful to a third party. Aggregated data may be used to model performance and improve maintenance schedules, lead to proactive maintenance activities anticipating e.g. component wear on instruments that have not yet been used to the same extent as other instruments that have encountered a wear error and many other advantages are contemplated.
The third party 1650 may be a back-office associated with the proprietor of the system 1000 and/or instrument modules 2000 and may perform license management functions for software applications 1400 distributed by the system 1000. Typically, system 1000 is implemented in a “cloud computing” environment, although interface module 2700 is ideally provided in hardware, embedded in the laboratory in which the instruments 1500 are located. The cloud environment enables additional functionality to be added to instrument modules 2000 by wireless deployment of software patches on a “push” or “pull” basis, and upgrades of features over time. Additionally, software patches and additional functionality for one or more instruments 1500 may be purchased using an instrument module 2000 and, once unlocked, deployed from servers 1700 to the instruments via interface module 2700.
The functionality may further include asset tracking of instruments and customers that are using those instruments by instrument vendors. Any technical issues pertaining to an instrument may be directed to the instrument vendor together with user information, instrument identification and logged data, such that the instrument vendor can triage the instrument before a service call is requested.
It is to be understood that various modifications, additions and/or alterations may be made to the parts previously described without departing from the ambit of the present invention as defined in the claims appended hereto.
