[0039] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the invention. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present invention are not shown or described in the specification. This is to avoid obscuring the core parts of the invention with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0040] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0041] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages).

[0042] In modern clinical laboratories, fully automated analyzers are core equipment. Their operation is complex, involving real-time monitoring of various consumables (such as cleaning solutions, reaction vessels, and substrate solutions) and potential malfunctions (such as needle blockage, photometer abnormalities, and mechanical jamming). Currently, instrument status is obtained primarily through two methods: 1. Fixed status indicator lights: A few critical alarms (such as serious malfunctions) are equipped with indicator lights, but the information provided is extremely limited, failing to indicate specific consumable levels or general warnings. 2. Software menu query: Operators must access the instrument's software interface and navigate through multiple menus to view detailed consumable status, error logs, and other information. This method suffers from deeply hidden information and cumbersome operation. When the operator is not near the instrument, global status information is not on the main interface, making it easy to miss warning messages (such as "cleaning solution is running low"), leading to test interruptions and impacting laboratory efficiency. Related technologies typically employ instruments with simple screensavers or standby interfaces, which usually only display the time, logo, or fixed text, failing to dynamically reflect the instrument's real-time status. Alternatively, the analyzers may have conventional touchscreen operating software, requiring users to actively query for status information. In summary, these technologies lack an intelligent display solution that can automatically optimize information presentation based on the usage scenario, enabling convenient perception of instrument status without interfering with normal operation.

[0043] The main shortcomings and deficiencies of the related technologies include: 1. Poor instrument status visibility: Key consumable reserves and general fault warning information are buried deep within the software. Operators cannot quickly and intuitively grasp the overall health of the instrument when not in operation, which can easily lead to unexpected downtime caused by consumable depletion or the accumulation of minor faults. 2. Low human-computer interaction efficiency: When operators are loading samples or querying results in front of the instrument, they must interrupt the current workflow, switch to the status query interface, and then switch back afterward if they want to check the status, thus disrupting the process. 3. Lack of scene adaptability: The existing display modes are fixed, either a full-function operation interface (interfering with status browsing) or a simple standby screen (lacking information), and cannot automatically provide the most appropriate information presentation based on the two typical scenarios of "manned operation" and "unmanned inspection".

[0044] To address the aforementioned issues, this application proposes a display control method for an in vitro diagnostic analyzer. The in vitro diagnostic analyzer includes a human-machine interface (HMI) for displaying the analyzer's status information. The display control method involves: acquiring the distance between a target object and the analyzer; determining whether the target object meets a preset first distance condition based on the distance; controlling the HMI to display a first display interface when the distance meets the first distance condition; wherein the first display interface includes at least several interactive controls for the analyzer, which perform at least one function: sample entry, item selection, test start, result query, and report printing; and controlling the HMI to display a second display interface when the distance does not meet the first distance condition; wherein the second display interface displays at least the real-time remaining quantities of various consumables used by the analyzer.

[0045] Figure 1 A flowchart of a display control method for an in vitro diagnostic analyzer provided in an embodiment of this application is shown. The in vitro diagnostic analyzer includes a human-machine interface, which is used to present the status information of the in vitro diagnostic analyzer. The following is a detailed description.

[0046] Step S10: Obtain the distance between the target object and the in vitro diagnostic analyzer.

[0047] In some embodiments, at least one non-contact sensor can be used to continuously or periodically acquire signals, and the distance between the target object and the in vitro diagnostic analyzer can be obtained by data processing and feature extraction of the signals. Alternatively, a monocular camera combined with a lightweight human detection algorithm can be used to replace the aforementioned non-contact sensor, or a single, lower-cost infrared pyroelectric sensor can be used to roughly determine whether the relationship between the target object and the in vitro diagnostic analyzer is "close" or "far" by detecting the movement area of ​​the target object.

[0048] For example, a time-of-flight (ToF) sensor can be used to calculate the distance between the target object and the in vitro diagnostic analyzer by emitting light pulses and measuring the time it takes for them to reflect back.

[0049] Step S20: Determine whether the target object meets the preset first distance condition based on the distance.

[0050] In some embodiments, an effective operating distance threshold D is set, for example, D = 1.2 meters. When the distance between the target object and the in vitro diagnostic analyzer is less than D, it is determined that the preset first distance condition is met; otherwise, it is determined that the preset first distance condition is not met. The effective operating distance threshold D can be configured via software according to the instrument installation environment (e.g., the size of the laboratory space).

[0051] Step S30: When the distance meets the first distance condition, control the human-computer interaction interface to present the first display interface.

[0052] In some embodiments, when the distance meets a first distance condition, it is determined to be a "manned state." At this time, the human-machine interface displays a first display interface, which can be considered as entering a "detailed operation interaction mode." The first display interface is a rendered and displayed standard graphical user interface of the in vitro diagnostic analyzer. The first display interface includes at least a number of interactive controls of the in vitro diagnostic analyzer. The interactive controls are used to implement at least one function among sample entry, item selection, start test, result query, and report printing. The detailed operation interaction mode is a display mode defined in this application. In this mode, the main content of the human-machine interface consists of interactive controls for various functions.

[0053] Step S40: If the distance does not meet the first distance condition, control the human-computer interaction interface to present the second display interface.

[0054] In some embodiments, when the distance does not meet the first distance condition, the system is determined to be in an "unmanned state." At this time, the human-machine interface displays a second display interface, which can be considered as entering a "global status overview mode." The second display interface is used to display at least the real-time remaining quantities of various consumables used by the in vitro diagnostic analyzer. Specific consumable items can be customized according to the configuration of different instrument models. The global status overview mode is a display mode defined in this application. In this mode, the main content of the human-machine interface is a centralized, visual summary of the instrument's key operating parameters and status, rather than operation buttons for direct control of the instrument.

[0055] For example, a status card is generated for each key consumable in the second display interface. In the "Reaction Cup" status card, a graphical balance bar is displayed, such as 0% to 100%, and the number of remaining reaction cups is shown, such as "1500 remaining". In the "Cleaning Fluid" status card, a similar graphical balance bar is displayed, along with the estimated number of tests, such as "Approximately 500 times". The status cards for "Acid / Alkaline Solution" and "Substrate Solution" are similar and will not be described further here.

[0056] In some embodiments, both the first and second display interfaces generate final display frame buffer data by invoking different display rendering logics and obtaining corresponding status data from the real-time data bus of each functional module of the in vitro diagnostic analyzer. The display frame buffer data can be output to the display driver circuit to drive the human-machine interface (i.e., the display screen) to refresh, and can also synchronously control the audible and visual alarm for subsequent alarm functions. A frame buffer, in computer graphics, is a memory area used to temporarily store a frame of image data, which will be sent to the human-machine interface for display.

[0057] According to the display control method for an in vitro diagnostic analyzer described in the above embodiments, the distance between the target object and the in vitro diagnostic analyzer is used to determine whether the target object meets a preset first distance condition. Based on the result of this determination, the display interface of the human-machine interface is dynamically switched to achieve scene-adaptive information presentation. When the distance meets the first distance condition, the human-machine interface is controlled to display a first display interface. This first display interface includes at least several interactive controls for the in vitro diagnostic analyzer. These controls enable at least one function: sample entry, item selection, start testing, result query, and report printing, allowing users to perform corresponding operations through the first display interface. When the distance does not meet the first distance condition, the human-machine interface is controlled to display a second display interface. This second display interface displays the real-time remaining quantities of various consumables used by the in vitro diagnostic analyzer, allowing passersby to visually check the remaining quantities. The different display interfaces switch based on the distance between the target object and the in vitro diagnostic analyzer, eliminating the need for manual switching and making the human-machine interaction process more natural, efficient, and consistent with actual laboratory workflows.

[0058] In some embodiments, the in vitro diagnostic analyzer further includes a first sensor for detecting the distance between the target object and the in vitro diagnostic analyzer, wherein the first distance condition includes a distance threshold.

[0059] Determine whether the target object meets the preset first distance condition based on distance, including:

[0060] Determine if the distance is less than the distance threshold.

[0061] For example, the first sensor is a ToF sensor with a distance threshold of 1.2 meters. The distance between the target object and the in vitro diagnostic analyzer is obtained in response to the detection signal of the ToF sensor, and it is determined whether the distance is less than 1.2 meters.

[0062] In some embodiments, the in vitro diagnostic analyzer further includes a second sensor for identifying whether the target object is a human body;

[0063] Determine whether the target object meets the preset first distance condition based on distance, including:

[0064] The system acquires the recognition results from the second sensor, determines whether the distance is less than the distance threshold, and determines whether the target object is a human body based on the recognition results.

[0065] In some embodiments, a combination of a first sensor and a second sensor is used. The first sensor is used to detect the distance between the target object and the in vitro diagnostic analyzer, and the second sensor is used to identify whether the target object is a human body. That is, the first sensor is used to accurately measure the distance between the target object and the in vitro diagnostic analyzer, while the second sensor is used to detect human movement and the presence of a human body. When the first sensor detects that the distance between the target object and the in vitro diagnostic analyzer is less than a distance threshold, and the second sensor confirms that the target object is a human body, then it is determined that a preset first distance condition is met, that is, it is determined to be a "person-occupied state".

[0066] For example, the first sensor is a ToF sensor, and the second sensor is an infrared pyroelectric sensor.

[0067] In some embodiments, when the distance meets a first distance condition, controlling the human-computer interaction interface to display a first display interface includes:

[0068] When the distance meets the first distance condition and the duration of meeting the first distance condition is greater than the preset first time threshold, the human-computer interaction interface is controlled to display the first display interface.

[0069] When the distance does not meet the first distance condition, the human-computer interaction interface is controlled to display a second display interface, including:

[0070] When the distance does not meet the first distance condition and the duration of the failure to meet the first distance condition is greater than the preset second time threshold, the human-computer interaction interface is controlled to display the second display interface.

[0071] In some embodiments, to prevent frequent interface switching on the human-machine interface caused by a target object briefly passing by the in vitro diagnostic analyzer, a first time threshold T1 and a second time threshold T2 can be set. These two time thresholds are essentially state confirmation delays and can be configured via software according to the instrument installation environment (such as the size of the laboratory space). For example, T1 can be 2 seconds. Display is triggered only after the distance meets the first distance condition and the duration of meeting the first distance condition is greater than 2 seconds, i.e., the state is maintained for 2 seconds, thus controlling the human-machine interface to display the first display interface. Especially during interface switching, if a user briefly passes by the in vitro diagnostic analyzer and the duration of their stay does not exceed 2 seconds, the current display interface of the in vitro diagnostic analyzer will remain unchanged, and the interface will not switch due to changes in the user's distance.

[0072] In some embodiments, the second display interface includes multiple consumable status display cards, each consumable status display card being used to display the real-time remaining quantity of the corresponding consumable; the display control method further includes:

[0073] In response to the real-time remaining amount of consumables in the consumables status display card being less than a preset remaining amount threshold, the alarm card is triggered to display and an alarm signal is issued.

[0074] In some embodiments, the alarm card includes an alarm code, a consumable status description, an alarm notification time, and suggested operating steps. The consumable status description indicates that if the consumable balance is 0, the message "Balance 0, cannot test" will be displayed; if the balance is less than a preset threshold, the message "Insufficient consumable usage, needs replenishment" will be displayed. This status description prompts the user to replace the consumable in a timely manner to ensure the instrument can operate normally. The alarm notification time indicates the moment the alarm occurred, presented to the user. Suggested operating steps refer to the alarm status information, such as suggesting replacing the reaction cup consumable, replacing the cleaning solution consumable, or requiring a shutdown and re-initialization restart. The instrument automatically performs filling and maintenance to ensure the tubing is full of liquid and prevent abnormal instrument testing. The background color of the alarm card can be set according to the alarm level; for example, red represents a serious fault, and yellow represents a warning. The second display interface can set an instrument alarm queue to arrange pending alarm information sequentially. If any alarm information remains unresolved or uneliminated, the corresponding alarm card will be displayed full-screen to maximize the warning and reminder effect. The presentation style of alarm information (cards, lists, icon colors) can be customized according to the configuration of different instrument models.

[0075] In some embodiments, when the alarm card is displayed in full screen, an audible and visual alarm will also be triggered simultaneously, controlling the buzzer to emit a sound mode corresponding to the alarm level, and the alarm indicator light will also flash.

[0076] Please refer to Figure 2 In some embodiments, the display control method further includes steps S50 to S60, which are described in detail below.

[0077] Step S50: In response to the first alarm signal, a prompt bar is displayed at a preset position on the first display interface.

[0078] When a user clicks on the notification bar, step S60 is executed: display the alarm card corresponding to the notification bar.

[0079] In some embodiments, the notification bar displays an alarm icon and consumable balance. Its preset location is the top or side of the first display interface. The first alarm signal is the highest priority alarm signal. Highest priority indicates that during the period when the first alarm signal is triggered, all other alarm information and / or user operations are suspended until the first alarm signal is cleared. The consumable balance is presented as a percentage, for example, 10% of the cleaning fluid remains, meaning new samples cannot be tested, or 0% of the cleaning fluid remains, meaning the instrument stops testing. The first alarm message can be positioned at 0% consumable balance, indicating that the instrument cannot continue testing and manual intervention is required to reassemble the consumables.

[0080] In some embodiments, considering that the first display interface usually displays user operations, but if there is a highest priority alarm, a semi-transparent persistent alarm bar will be retained at the top or side of the first display interface to display the alarm icon and brief information. Clicking the bar will expand the full-screen alarm card, ensuring that even if the interface that displays user operations is presented, the alarm information will still be retained on the interface so that the user can always pay attention to the alarm information and avoid the alarm affecting the normal operation of the in vitro diagnostic analyzer.

[0081] Please refer to Figure 3 In some embodiments, the display control method further includes steps S70 to S80, which will be described in detail below.

[0082] If the distance does not meet the first distance condition and no alarm signal is received within the preset first duration period, then step S70 is executed: control the display brightness of the second display interface to the first brightness value.

[0083] Step S80: In response to an alarm signal or when a distance is detected that meets a preset second distance condition, control the display brightness of the second display interface to a second brightness value.

[0084] In some embodiments, the second brightness value is greater than the first brightness value. The first duration can be configured via software according to the instrument installation environment (e.g., laboratory space size). The second distance condition can be the same as the first distance condition, and will not be described further here.

[0085] For example, in an "unattended state," if no alarm signal is received for a period of time, such as 5 minutes, the brightness of the second display interface can be reduced to save energy while keeping the status information visible. Once personnel are detected approaching or a new alarm is generated, the brightness of the second display interface should be immediately restored to the maximum brightness.

[0086] In some embodiments, during the switching process between the first display interface and the second display interface, smooth transition animations such as fade-in / fade-out and sliding can be added to enhance the user experience.

[0087] In some embodiments, voice queries can be supported in an "unmanned" state, for example, a voice query to determine how many reaction cups are left.

[0088] In some embodiments, this application proposes an intelligent display control method for in vitro diagnostic analyzers. The core of this method lies in sensing the positional relationship between personnel and the instrument using non-contact sensors and dynamically switching the display mode accordingly to achieve scene-adaptive information presentation. Specific innovations include: 1. Personnel-based display mode decision-making: Utilizing infrared, ToF, or vision sensors, the system determines in real-time whether the operator is in the "operable area" in front of the instrument and automatically decides whether to enter the "global status overview mode" or the "detailed operation interaction mode." 2. Enhanced information presentation in unoccupied states: When unoccupied, the display automatically switches to the global status interface, highlighting and centrally displaying the real-time remaining levels of all key consumables, the instrument's self-test status, and any active alarm / warning information in a graphical and card-based manner, making it readily apparent to passersby. 3. Seamless interface switching and intelligent prompts in occupied states: When personnel are detected approaching, the display automatically and seamlessly switches back to the full-function operation software interface. Simultaneously, if there are unprocessed high-priority alarms, a non-intrusive, persistent prompt bar can be provided at the edge of the operation interface to ensure that critical anomalies are not ignored. Based on the above innovations, this application has the following advantages: (1) It achieves "panoramic transparency" and "convenient accessibility" of instrument status: Through the global overview interface in "unmanned state", the most critical status information is freed from the multi-layer menu and transformed into visual information that can be seen at a glance, which greatly facilitates the inspection and status control of multiple instruments by laboratory staff and effectively prevents unexpected shutdowns caused by failure to detect the depletion of consumables or potential faults in time; (2) It optimizes the human-computer interaction process and improves the operating efficiency: The display mode automatically switches according to the intention of the personnel. When the operator approaches, they directly enter the working interface, and after leaving, it automatically switches to the status dashboard without any manual switching operation, making the interaction process natural and efficient, which is in line with the actual workflow of the laboratory; (3) It enhances the timeliness and effectiveness of alarms: In "unmanned state", the alarm information can be presented in the most eye-catching way (full screen + sound and light) to ensure that even if no one is operating, it can be immediately discovered by nearby personnel. In "manned state", the persistent prompt bar ensures that the key alarms are not missed during the operation, thereby shortening the fault response time and ensuring laboratory safety and testing quality.
