The disclosure herein generally relates to a laboratory equipment interface and a method of associating empirical information for a laboratory animal from a plurality of animal laboratory devices within a data store.
An animal laboratory may have many pieces of laboratory equipment used to generate empirical information about experimental animal subjects. Some animal laboratories have thousands or millions of animals in the form of rodents, for example mice and/or rates. It is laborious to generate empirical information for large animal populations, especially when using many different pieces of laboratory equipment and manually entering the empirical data against a record for each animal.
Mistakes do occur in recording empirical values. An empirical value may be recorded against the wrong animal identity. This may effect the integrity of the experimental data and the experiment itself. Not only may this mask the outcomes of the experiment, it may be extremely costly for experiments involving a large number of animals and/or expensive animals. Some mice cost $1,000 or more.

Embodiments will now be described by way of example only with reference to the accompanying figures in which:
The processor 34 receives animal identification information by animal laboratory device 18 reading an identification tag 39, which in this embodiment is attached to the animal. In this embodiment, the identification tag 39 is a radio frequency identification tag implanted in the animal, however it may be an identification tag readable using machine vision, or generally any suitable form of identification tag. The radio frequency identification tag has stored therein the animal identification information in the form of a sequence of symbols. Multiple devices 18-28 can be simultaneously connected. In an otherwise identical embodiment, a tag identification (TID) is read and sent to the laboratory equipment interface 10, which sends a request and subsequently receives the animal identification information associated with the TID from the data store. The TID and the animal identity are preassociated in the data store. Because the TID and the animal identify information are both indicative of the one animal, the TID is merely a different form of the animal identity information.
An example of the text in an information transmission unit 36 in JSON format is:
The animal identification information is used as a key for relating data base records in the data store. This generally eliminates the possibility of human bias and error in experiments. The integrity of experimental studies may be improved. An incorrectly identified and/or processed animal may be euthanised.
When the identification tag is read and received by the laboratory equipment interface 10, the laboratory equipment interface may send the tag ID to the remote data store. The remote data store may respond by sending information back to the laboratory equipment interface 10 in the form of a text file, which in this embodiment is JSON formatted. An example of such information is:
The processor 34 receives user instruction information indicative of an instruction for a user in the form of an animal technician to initiate the generation of the empirical information relating to the laboratory animal 38. The processor communicates to the user the user the instruction. The user processor causes an electronic display 48 to display the instruction to the user.
Generally, but not necessarily, the laboratory comprises a plurality of animals and the instructions are for the user to initiate the generation of empirical data in relation to a specified animal of the plurality of animals. The user may inadvertently select the incorrect animal. The processer confirms that the user instruction information comprises the animal identification information generated by the at least one of the plurality of animal laboratory devices, so to ensure that the right animal has engaged the at least one animal laboratory device.
The processor 34 triggers an alert when the processor determines that the empirical information satisfies an alert condition. The alert may be in the form of, for example, an audible alert, a visible alert, for example an error icon and/or error message text displayed on the display 48, or a message sent via the communications interface 30 to another machine. For example, an alert condition may be that the animal's mass has decreased by more than a percentage value. The user may be alerted if the animal is at risk or there is an error.
The laboratory equipment interface 10 comprising pre-loaded animal laboratory device software in the form of animal laboratory device drivers for each of the plurality of animal laboratory devices 16-28.
Including the animal identification and the empirical data in the same data unit may improve the integrity of the data. It is less likely that empirical data will be recorded against the wrong animal identity in the data store. The information transmission unit is a text stream in the form of a text file holding information in a data-interchange format. In the present embodiment the information transmission unit is a JSON file, which is human readable and writable. A HTTP over transport layer security (HTTPS) session between the laboratory equipment interface 10 and the server 32 is started. A POST command is used to send the information transmission unit 36 from the laboratory equipment interface 10 to the server 32. In alternative embodiments, the information transmission unit 10 comprises a XML file, a CSV file, or generally be any suitable information transmission unit. FTP or any suitable service may be used instead of HTTPS.
The laboratory equipment interface has a network address in the form of a IEEE 802.3 MAC address and an internet protocol address, and the processor includes the network address in the information transmission unit. The network address is included by the processor 34 in the information transmission unit 36 and associated in the data store with the empirical information. This enables tracking of the source of the empirical information.
The at least one communication interface comprises at least one personal area network interface. For example, communications interface 12 may be a Blue Tooth interface, communications interface 14 may be a universal serial bus (USB) interface, and communications interface 16 may be a RS-232 interface. One of the plurality of communication interfaces may be, however, a different type of interface, for example an IEEE 802.11 (“Wi-Fi”) communications interface, a local area network interface in the form of an IEEE 802.3 (“Ethernet”) communications interface, or a LPWAN interface, for example Sigfox. The communications interface 30 is for a local area network that is connected to an internetwork, for example the Internet. The remote data store 32 comprises in this example a computer server running data base software connected to a respective local area network that is connected to the internet.
The laboratory equipment interface 10 comprises a housing in which the processor 34 is housed and a connected electronic touch screen display 48 that is hingedly mounted for user selection of the viewing angle. The laboratory equipment interface 10 comprises a power management system including mains to DC conversion and a battery. In the housing is a printed circuit board assembly to which is mounted non-volatile memory in the form of flash memory, random access memory and a central processing unit (CPU) in the form of a multicore intel processor. The CPU runs any suitable operating system, for example any of Windows, LINUX and IOS, for example. The non-volatile memory has factory preloaded device driver software for the plurality of animal laboratory devices, which may replace the need for the user to load device driver software. This embodiment of the laboratory equipment interface 10 includes a plurality of communication interface types, for example for a plurality of Blue Tooth Connections, multiple USB ports, and multiple RS232 ports.
An example of how a user interacts with the laboratory equipment interface 10 is now described. The user connects an identification tag reader 18 in the form of a RFID tag reader to the laboratory equipment interface 10 via a communications interface 12. The user then connects at least one animal laboratory device 24, and generally a plurality of animal laboratory devices, to one or more communications interfaces 14. The user then turns the laboratory equipment interface 10. The laboratory equipment interface 10 establishes communications with the remote data store. The user causes the identification tag reader 18 to read the RFID tag attached to an animal. The laboratory equipment interface 10 then displays at least one of the following:
The displayed information may be sent by the data store to the laboratory equipment interface 10, which is subsequently displayed.
The user then causes one of the animal laboratory devices 18-28 to generate empirical information about the animal, for example by weighing the animal or measuring a tumour size with electronic callipers, which the animal laboratory device sends to the laboratory equipment interface 10. The empirical information is displayed to the user on the electronic display. The user commands the laboratory equipment interface 10 to send the empirical information about the animal to the remote data store 32 by interacting with the user interface, in this embodiment by pressing the save button displayed on the tough screen. The laboratory equipment interface 10 generates the information transmission unit, and sends it to the remote data store via the communication interface 30 for association of the empirical information with the animal identification information.
