Patent Application
20200312448
This application is a continuation of EP 19166340.0, filed Mar. 29, 2019, which is hereby incorporated by reference.
The present disclosure generally relates to an analytical laboratory, in particular, an in-vitro diagnostic laboratory, a computer implemented method of operating an analytical laboratory, as well as a computer program product comprising instruction for operating an analytical laboratory.
In vitro diagnostic testing can have a major effect on clinical decisions, providing physicians with pivotal information. In analytical laboratories, in particular, in-vitro diagnostic laboratories, a multitude of analyses on biological samples are executed by laboratory instruments in order to determine physiological and biochemical states of patients, which can be indicative of a disease, nutrition habits, drug effectiveness, organ function and the like.
Conventionally, laboratory users/technicians have to physically observe all laboratory instruments to ensure proper operation. With rising complexity and scale of analytical laboratories, there is a need to provide productivity tools to manage the multitude of laboratory instruments within large analytical laboratories. One particular requirement of such productivity tools is to provide up-to-date and aggregated information on the operational status of the laboratory instruments to enable laboratory users/technicians to monitor the laboratory instruments with reduced effort and less risk of oversight.
Several productivity solutions are known which provide a dashboard type consolidated monitor of laboratory instruments. Such productivity solutions are of great use for the laboratory users/technicians only if they allow monitoring of most—or even all—laboratory instruments within large analytical laboratories. Otherwise, the laboratory users/technicians would still need to individually monitor a subset of instruments, a sub-optimal solution. However, known solutions require a data connection to the laboratory instruments monitored, in particular, access to the internal data stream(s) to and from the laboratory instruments. In practice, a data connection to all laboratory instruments is difficult to establish for several reasons: In most large analytical laboratories, the various laboratory instruments are from different vendors/providers. One particular provider of a productivity tool to monitor a laboratory is often not allowed access to the data connection of laboratory instruments of other vendors, for technological or security reasons or because certain instruments are designed as closed systems. Technological reasons—for not having access to the internal data stream to/from an instrument—comprise legacy instruments, which have not been designed with connectivity in mind, incompatible communication technologies, and the like. On the other hand, certain vendors intentionally design their instruments as closed systems to prevent competitors' access to instrument data. In addition, privacy regulations/concerns also pose limitations to access to the internal data stream of laboratory instruments.
Hence, there is a need for a productivity tool for a laboratory system that provides aggregated operational status of all laboratory instruments within an analytical laboratory, even without access to their respective internal data stream such as for legacy and/or third party instruments.
According to the present disclosure, a system and method for determining operational status of a plurality of laboratory instrument are disclosed. The method can comprise communicatively connecting a control unit to one or more laboratory instrument(s) of a first group, capturing one or more external surveillance stream(s) of one or more of a second group of laboratory instrument(s) by a surveillance device, and receiving an internal data stream from one or more laboratory instrument(s) of the first group by the control unit. The internal data stream(s) can comprise data indicative of an operational status of one or more laboratory instrument(s) of the first group. The method can also comprise receiving the external surveillance stream(s) of the laboratory instrument(s) of the second group by the control unit, processing the internal data stream(s) from the laboratory instrument(s) of the first group by the control unit to extract an operational status of one or more laboratory instrument(s) of the first group, processing the external surveillance stream(s) of the laboratory instrument(s) of the second group by the control unit to detect an operational status of one or more laboratory instrument(s) of the second group, outputting the operational status of any one of the laboratory instrument(s) of the first group via a lab monitoring interface, and outputting the operational status of any one of the laboratory instrument(s) of the second group via a lab monitoring interface.
Accordingly, it is a feature of the embodiments of the present disclosure to provide a productivity tool for a laboratory system that provides aggregated operational status of all laboratory instruments within an analytical laboratory, even without access to their respective internal data stream such as for legacy and/or third party instruments. Other features of the embodiments of the present disclosure will be apparent in light of the description of the disclosure embodied herein.
The following detailed description of specific embodiments of the present disclosure can be best understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:
In the following detailed description of the embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration, and not by way of limitation, specific embodiments in which the disclosure may be practiced. It is to be understood that other embodiments may be utilized and that logical, mechanical and electrical changes may be made without departing from the spirit and scope of the present disclosure.
The embodiments herein disclosed address the need for a productivity tool for a laboratory system that provides aggregated operational status of all laboratory instruments within an analytical laboratory, even without access to their respective internal data stream such as for legacy and/or third party instruments by combining determining operational status of a first group of instruments by capturing and processing internal data streams comprising data indicative of an operational status, determining operational status of a second group of instruments by capturing and processing external surveillance stream(s) of one or more laboratory instrument(s) of the second group, and outputting the operational status of any one of the laboratory instrument(s) of the first and/or second group via the lab monitoring interface.
The operational status of a laboratory instrument can comprise indications related to the instrument's readiness to process biological samples, including but not limited to
According to some embodiments, the productivity tool for an analytical laboratory can comprise a control unit, a surveillance device and a lab monitoring interface. The control unit can be communicatively connectable to one or more laboratory instrument(s) of a first group in order to capture an internal data stream from the laboratory instrument(s) of the first group.
According to some embodiments, the internal data stream(s) can comprise signals from a user interface of the instrument, signals of human interaction devices of the instrument (such as a keyboard, a mouse and/or a touchscreen), log files of the laboratory instrument(s), external data communication to and from a laboratory middleware or laboratory information system (LIS), and/or alert signals of the laboratory instrument. The internal data stream(s) can, for example, comprise any kind of signal and data, which directly indicates an operational status of an instrument.
Surveillance device(s) external to the laboratory instrument(s) can be arranged to capture one or more external surveillance stream(s) of one or more of a second group of laboratory instrument(s). The second group of laboratory instrument(s) can, for example, comprise instruments for which a communicative connection to capture an internal data stream indicative of their operational status is impeded or not possible (closed systems, different vendors or legacy instruments).
According to some embodiments, the laboratory instrument(s) of the first group can provide a type of data connection for internal data stream(s) that can be different from a type of data connection for internal data stream(s) of the laboratory instrument(s) of the second group. ‘Type of data connection’ here can refer to external accessibility to the internal data stream(s), e.g. type of interface, type of data format, type of encryption, and/or type of access control. In one example, a type of data connection for internal data stream(s) of the of the laboratory instrument(s) of the first group can differ from a type of data connection for internal data stream(s) of the of the laboratory instrument(s) of the second group in that the laboratory instrument(s) of the first group may provide a data connection for accessing internal data stream(s) and the laboratory instrument(s) of the second group may not provide a data connection for accessing internal data stream(s), as it, for example, can be the case for legacy devices. In another example, the first group can comprise of laboratory instrument(s) of a first vendor and the second group can comprises of laboratory instrument(s) of other vendors, wherein each vendor can control the access to internal data stream(s) using a different access control so that the first vendor cannot readily access the internal data stream(s) of the other vendors.
In order to collect operational status of both groups of laboratory instruments, the control unit can be configured to receive and process both the internal data stream(s) from the laboratory instrument(s) of the first group and the external surveillance stream(s) of the laboratory instrument(s) of the second group. In processing the internal data stream(s) from the laboratory instrument(s), the control unit can be configured to extract the operational status of one or more laboratory instrument(s) of the first group, wherein the internal data stream(s) can, for example, readily comprise data indicative of the operational status. In processing the external surveillance stream(s) of the laboratory instrument(s) of the second group, the control unit can be configured to detect an operational status of one or more laboratory instrument(s) of the second group, wherein the processing can, for example, comprise processing of the external surveillance stream(s) to identify elements of the internal data stream(s) which can be representative of a particular operational status.
As it is determined, the operational status of any one of the laboratory instrument(s) of the first and/or second group can be output via the lab monitoring interface.
These embodiments can be advantageous as they can allow overall (all-inclusive) monitoring of an entire laboratory comprising instrument(s) both with access to their internal data stream (e.g. fully integrated or open systems) and without access to their internal data stream (e.g. legacy systems or closed systems).

Thereafter, in a step 100, the control unit can receive the internal data stream(s) from the laboratory instrument(s) of the first group, the internal data stream(s) comprising data indicative of an operational status of one or more laboratory instrument(s). In subsequent steps 102 and 104, the control unit can process the internal data stream(s) from the laboratory instrument(s) of the first group in order to extract (in step 104) an operational status of one or more laboratory instrument(s) of the first group.
In a—possibly parallel—sequence of steps 200 to 204, the operational status of the laboratory instrument(s) of the second group can be determined. Firstly, in step 200, one or more external surveillance stream(s) of one or more of a second group of laboratory instrument(s) can be captured by one or more surveillance devices. Thereafter, in step 202, the control unit can receive and process the external surveillance stream(s) of the laboratory instrument(s) of the second group to detect (in step 204) an operational status of one or more laboratory instrument(s) of the second group.
In step 300, the operational status of any one of the laboratory instrument(s) of the first and/or second group can be outputted via the lab monitoring interface.
According to further embodiments, the method can compromise capturing a video signal, e.g., a video image, of one or more of the second group of laboratory instrument(s). Accordingly, the step of processing the external surveillance stream(s) of the laboratory instrument(s) of the second group to detect an operational status of one or more laboratory instrument(s) of the second group can comprise one or more of the following: detecting changes of a user interface of the laboratory instrument(s), e.g., changes of color and/or the appearance of one or more icons of bright color; and/or detecting movement and/or position of a part of the laboratory instrument(s), e.g., an open or closed position of compartments for loading consumables of the laboratory instrument(s); and/or detecting visual status indicators, e.g., an emission of status LEDs arranged on a housing of the laboratory instrument(s); and/or capturing a thermal image of one or more of the second group of laboratory instrument(s) and determining an operational temperature of at least a part of the laboratory instrument(s) to determine the operational status of a laboratory instrument, e.g., distinguishing between a normal and abnormal operational status of the respective laboratory instrument(s).

The first time interval and the second time interval can be overlapping (e.g., identical) or non-overlapping. In an example where the lab monitoring interface 40 comprises an OHMD, the productivity tool can be configured to display the operational status of all the laboratory instrument(s) of the first and of the second group that are currently in the in the field of view of a wearer of the OHMD.
According to further embodiments, the productivity tool 5, e.g., a wearable device (e.g., an OHMD) comprised in the productivity tool 5, can be designed to detect a proximity of an operator to a surveillance device 30. The productivity tool 5, e.g., a wearable device thereof, can e.g., be configured to temporarily disable a surveillance device 30 arranged to capture an external surveillance stream of that particular laboratory instrument(s) 10. This can support protecting the privacy of the operator. According to some embodiments, the productivity tool 5 can be configured to re-enable the surveillance device 30 after the productivity tool 5, e.g., a wearable device thereof, no longer indicates proximity of an operator and/or after expiry of a specified timeout period.
In addition, or alternatively, the productivity tool can be designed to detect, e.g., using a wearable device such as an OHMD, the proximity of an operator to a laboratory instrument(s) 10 being monitored by a surveillance device 30. The productivity tool can be configured to temporarily disable the respective surveillance device 30 if the productivity tool detects that an operator is in proximity (e.g., within 2 meters) of the laboratory instrument(s) 10. In an example, the surveillance device 30 can comprise a video camera and if the productivity tool 5 detects that an operator is in proximity to a laboratory instrument 10 and that the video camera monitoring could have the operator could come into the field of vision of the video camera, the productivity tool 5 can temporarily disable the video camera. According to some embodiments, the productivity tool can be configured to re-enable the surveillance device 30 after the productivity tool no longer detects the operator in the proximity of the laboratory instrument 10.

The method can further comprise generating an overlay 46 on the field of view of an operator using an augmented reality device 44. The overlay can be generated such as to display operational status of a laboratory instrument in the field of view of the operator. The positioning of the operational status can allow the operator to associate the operational status with the respective laboratory instrument.
The method can further comprise detecting proximity of an operator to a laboratory instrument 10 and temporarily disabling the surveillance device 30 arranged to capture an external surveillance stream of that particular laboratory instrument(s) 10 to protect privacy of the operator.
A computer program product is proposed. The computer program product can comprise instructions which, when executed by a control unit 20 of an analytical laboratory 1, can cause the analytical laboratory 1 to perform the above method.
Furthermore, a productivity tool 5 for an analytical laboratory 1 having a plurality of laboratory instrument(s) 10 is proposed. The productivity tool can comprise one or more surveillance device(s) 30 external to the laboratory instrument(s) 10 arranged to capture one or more external surveillance stream(s) of one or more of the plurality of laboratory instrument(s) 10, a lab monitoring interface 40, and a control unit 20 communicatively connectable to the one or more surveillance device(s) 30 and to the lab monitoring interface 40. The control unit 20 can be configured to receive one or more external surveillance stream(s) of one or more of the plurality of laboratory instrument(s) 10, to process the external surveillance stream(s) of the one or more of the plurality of laboratory instrument(s) 10 to detect an operational status of at least one laboratory instrument(s) 10 of the one or more of the plurality of laboratory instrument(s) 10, and to output the detected operational status via the lab monitoring interface 40.
The one or more surveillance device(s) can comprise a camera that can be arranged to monitor a display on which data indicative of an operational status of a laboratory instrument is displayed. This productivity tool can be combined—if compatible and with the according adjustments—with any feature of the other productivity tools proposed herein, in particular with any feature that is connected to the second group (of laboratory instruments) of the other productivity tools proposed herein.
