Description

Technical Field

[0001] This invention relates to the field of touch screen technology, and in particular to a touch screen for preventing accidental touches suitable for medical device displays and a method for preventing accidental operation of the touch screen. Background Technology

[0002] With the maturity and popularization of touch screen technology, touch screens have been widely used in various electronic devices. Among them, medical device displays are also gradually adopting touch screen design to improve the ease of operation and interactive experience, especially suitable for medical scenarios such as doctors explaining the condition and treatment plan to patients.

[0003] Currently, conventional solutions for addressing touchscreen misoperations mostly rely on host-side software or the operating system to make judgments, using algorithms to identify invalid touch actions. However, in complex scenarios such as medical settings, these solutions still have significant drawbacks: on the one hand, due to electrical interference or the complexity of touch actions, host-side judgments are prone to misjudgment, leading to the blocking of valid operations or accidental touches triggering device responses; on the other hand, existing solutions often require additional software configuration or hardware adjustments to the host, which not only increases adaptation costs but may also affect the operational stability of medical devices, making it difficult to meet the stringent reliability requirements of medical scenarios.

[0004] Especially in scenarios where doctors explain things to patients using a touchscreen, accidental touches when hands are close to the screen occur frequently. Existing anti-accidental touch solutions cannot accurately meet the usage needs of this scenario. Misoperations may interfere with the continuity of the explanation and even affect the normal progress of the medical process. Summary of the Invention

[0005] This invention provides a method for preventing accidental touch operation of a touchscreen, comprising: turning on or off the anti-accidental touch function of an anti-touch zone defined on the touchscreen of the display by clicking a control button; in the on state, touch action data in the anti-touch zone is blocked and not transmitted to the host, and the host does not respond to the touch action; in the off state, touch action data of the entire touchscreen area is transmitted to the host normally, and the host responds normally.

[0006] According to one embodiment of the present invention, the effective operation area and the anti-touch area are pre-divided on the touch screen of the display, including: entering the anti-touch area division mode by long-pressing the control button, customizing the position, range and shape of the anti-touch area on the touch screen of the display, and dividing the effective operation area and the anti-touch area; after the setting is completed, saving the configuration and exiting the division mode.

[0007] According to one embodiment of the present invention, the control button is a physical button or a screen virtual button, wherein the physical button is integrated into the edge of the display, and the screen virtual button is displayed in a non-core display area of ​​the touch screen.

[0008] According to one embodiment of the present invention, the trigger duration of the long press control button is 1-3 seconds. During the long press, the touch screen displays a partition mode activation indicator, indicating that the anti-touch zone setting state has been entered.

[0009] According to one embodiment of the present invention, the shape of the anti-touch area includes a rectangle, a polygon, or an irregular shape. When customizing the settings, the boundary vertices of the anti-touch area are determined by touching the screen or the boundary is dragged to adjust the range.

[0010] The present invention also provides an anti-mistouch touchscreen, comprising: an auxiliary sensing area disposed on the outer edge of the touchscreen for assisting in identifying the start / stop status of the anti-mistouch function; a control module configured with control buttons for supporting single-click to start / stop the anti-mistouch function and long-press to enter the anti-mistouch zone division mode; a data acquisition module for acquiring touch action data of the entire area of ​​the touchscreen; a data configuration module for pre-storing custom configuration parameters of the anti-mistouch zone, and blocking touch data of the anti-mistouch zone when the anti-mistouch function is enabled; and a data transmission module for sending the valid touch data processed by the data configuration module to the host.

[0011] According to one embodiment of the present invention, the auxiliary sensing area is a ring or strip structure, which is arranged around the outer edge of the touch screen. When the anti-accidental touch function is confirmed to be enabled, the auxiliary sensing area emits a visual prompt signal.

[0012] According to one embodiment of the present invention, the long press trigger duration of the control module is preset to a range of 1-3 seconds. During the long press, the control module sends a partitioning mode start signal to the data configuration module.

[0013] According to one embodiment of the present invention, the shielding logic of the data configuration module is as follows: the collected touch data is compared with the pre-stored anti-touch zone parameters, and when it is confirmed that the touch position is located in the anti-touch zone, the touch data is discarded and not transmitted to the data sending module.

[0014] According to one embodiment of the present invention, if the anti-accidental touch function is confirmed to be off, the data configuration module does not perform a shielding operation, and the full-area touch data collected by the data acquisition module is completely transmitted to the host through the data sending module, and the host responds according to the normal logic.

[0015] This invention achieves precise and efficient anti-accidental touch effects. By dividing the effective operation area into an anti-touch area and in conjunction with a data shielding mechanism, it can effectively avoid accidental hand contact by doctors when explaining to patients in medical scenarios. At the same time, it can resist misoperation that may be caused by electrical environmental interference, completely improve the misjudgment problem existing in the prior art, and ensure the accuracy of medical device display operation.

[0016] This invention is highly adaptable and requires no additional cost. The relevant functions are directly integrated into the touch screen, without requiring any software configuration or hardware adjustment on the host side. It will not affect the operational stability of existing medical devices, can be adapted to various medical device displays, significantly reduces various costs in the adaptation and maintenance process, and successfully solves the pain point of existing solutions relying on host adaptation.

[0017] This invention is flexible, convenient and easy to use. It supports starting and stopping the anti-accidental touch function with a single click, and the position and shape of the anti-touch area can be customized by long press. It can adapt well to different explanation content and doctors' operating habits. The auxiliary sensing area on the outer edge of the touch screen can help identify the function status. Users can get started quickly without additional learning, effectively improving the efficiency of use in medical explanation scenarios.

[0018] This invention can fully guarantee the continuity of medical processes, effectively avoid problems such as interface jump parameter changes caused by misoperation, ensure that the process of doctors explaining the condition and treatment plan to patients is not disturbed, reduce the interruption of medical processes caused by misoperation, and further improve the smoothness of medical communication and diagnosis and treatment.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0026] The following is combined Figures 1-4 This invention describes a method for preventing accidental touch operation of a touchscreen and a touchscreen itself.

[0027] Figure 1 This is a flowchart of the anti-accidental touchscreen anti-misoperation method provided by the present invention. For example... Figure 1 As shown, the method includes the following: In step S100, by clicking the control button, the anti-mistouch function of the anti-touch zone 170 divided on the touch screen of the display is turned on or off; In step S200, in the turned-on state, the touch action data in the anti-touch zone 170 is blocked and not transmitted to the host, and the host does not respond to the touch action; In step S300, in the turned-off state, the touch action data of the entire area of ​​the touch screen is transmitted to the host normally, and the host responds normally.

[0028] Specifically, Figure 1 The illustrated process fully covers the entire process of preventing accidental touches, from operation triggering to data processing, and is suitable for medical explanation scenarios of medical device displays.

[0029] Step S100 enables quick activation and deactivation of the anti-accidental touch function through a simple single-click operation, with operation logic adapted to doctors' usage habits. The control button can be designed as a physical button or a virtual button on the screen, depending on the structure of the medical device display. Physical buttons are integrated into the edge of the display, while virtual buttons are displayed in non-core display areas of the touchscreen, avoiding obstruction of key explanatory screens. When the doctor needs to activate the anti-accidental touch function, a single click of the control button activates it. At this time, the auxiliary sensing area 110 on the outer edge of the touchscreen simultaneously emits a visual prompt signal, providing intuitive feedback that the function is activated. Clicking the control button again deactivates the anti-accidental touch function, and the prompt signal from the auxiliary sensing area 110 simultaneously terminates, allowing the doctor to monitor the function status in real time. It should be noted that the anti-touch area 170 here is pre-defined by entering the partitioning mode through a long press of the control button; its position, range, and shape are already adapted to specific explanatory needs, eliminating the need for repeated settings during activation and deactivation.

[0030] Step S200 corresponds to the data processing flow after the anti-mistouch function is enabled. After the function is enabled, the touch screen data acquisition module 130 will continuously collect touch action data of the entire area, and this data will be transmitted to the data configuration module 140 in real time. The data configuration module 140 has pre-stored the previously set anti-touch zone 170 parameters, and will accurately compare the collected touch data with the pre-stored parameters to determine whether the touch position is within the anti-touch zone 170. If it is confirmed that the touch action occurred in the anti-touch zone 170, the data configuration module 140 will directly discard the touch data and will not transmit it to the data sending module 150, thereby ensuring that the touch data cannot be sent to the host. Since the host does not receive the relevant data, it will not generate any response, effectively avoiding accidental operation such as interface jumps and parameter changes caused by the doctor's hand accidentally touching the anti-touch zone 170 during the explanation.

[0031] Step S300 corresponds to the normal operation procedure after the anti-mistouch function is turned off. When the doctor finishes explaining or needs to perform full-area operation on the touchscreen, the data configuration module 140 will stop performing data shielding after the anti-mistouch function is turned off. At this time, the touch data of the entire touchscreen area collected by the data acquisition module 130 will be completely transmitted to the data configuration module 140, which will then forward it directly to the data sending module 150, and finally to the host. After receiving the full-area touch data, the host will respond according to the normal operation logic to ensure that the doctor can perform normal clicks, swipes, and other operations on the touchscreen, meeting the normal usage requirements of the medical device display. The entire process does not require any additional configuration or hardware adjustment to the host; the flexible switching between anti-mistouch and normal operation can be achieved solely through the module collaboration of the touchscreen itself, balancing operational convenience and reliability in the medical scenario.

[0032] Figure 2 This is a flowchart illustrating the pre-defined effective operating area 160 and anti-touch area 170 on the touchscreen of the display. For example... Figure 2 As shown, according to an embodiment of the present invention, the effective operation area 160 and the anti-touch area 170 are pre-divided on the touch screen of the display, including: in step S110, by long-pressing the control button, entering the anti-touch area 170 division mode, the position, range and shape of the anti-touch area 170 are customized on the touch screen of the display to divide the effective operation area 160 and the anti-touch area 170; in step S120, after the setting is completed, the configuration is saved and the division mode is exited.

[0033] Specifically, Figure 2 The process shown focuses on the personalized division of the anti-touch zone 170 and the effective operation zone 160. The operation logic is simple and adaptable to the actual use needs of doctors in medical scenarios.

[0034] Step S110 is the operation step for dividing the anti-touch zone 170. Its design fully considers the convenience of operation and the flexibility of settings. When the doctor needs to customize the area, he can trigger the division mode by pressing and holding the control button. The trigger duration of the press is preset to 1-3 seconds. This duration avoids accidental triggering by short presses and does not affect the operation efficiency due to excessive duration, perfectly meeting the fast-paced use needs of medical scenarios. During the press and hold, the touch screen will simultaneously display a division mode activation indicator. This indicator can be manifested as a flashing screen border or a pop-up prompt icon, clearly informing the doctor that the anti-touch zone 170 setting state has been successfully entered. At the same time, the auxiliary sensing area 110 on the outer edge of the touch screen can also emit a slight visual signal, forming a double prompt with the activation indicator to avoid misjudgment of operation.

[0035] The shape of the control buttons can be flexibly selected according to the design of the medical device display. If they are physical buttons, they are integrated into the edge of the display; if they are virtual buttons, they are displayed in the non-core display area of ​​the touch screen. Neither form will interfere with the screen display content, ensuring that doctors can view the existing information on the screen during the setup process. After entering the partitioning mode, doctors can freely define the position, range, and shape of the anti-touch zone 170 according to the explanation needs: if the explanation content is concentrated in the center of the screen, such as lesion images or treatment plan diagrams, the easily accidentally touched areas around the screen can be set as the anti-touch zone 170; if specific areas need to be operated, such as the location of parameter adjustment buttons, the anti-touch range can be precisely defined to avoid that area. The anti-touch zone 170 supports rectangular, polygonal, or irregular shapes. Doctors can directly touch the screen to determine the boundary vertices of the anti-touch zone 170, or long-press the boundary and drag to adjust the range. The operation method is consistent with regular touch screen interaction, requiring no additional learning cost. For example, when defining a rectangular anti-touch zone 170, tapping two opposite corners of the screen will define the range. When defining an irregular shape, multiple vertices can be tapped consecutively to form a closed area. When defining a polygon, tapping a vertex and confirming will form the desired shape. As the anti-touch zone 170 is defined, the unselected area on the touchscreen automatically becomes the effective operating area 160. The boundary between the two can be distinguished visually using dotted lines, different colored shadows, etc., ensuring that doctors can clearly understand the division results.

[0036] Step S120 is the final step in the area division process, ensuring the stable reuse of the settings. After the doctor completes the adjustment of the position, range, and shape of the anti-touch zone 170, no additional complex operations are required. The system will automatically trigger the configuration saving process, accurately storing the set parameters of the anti-touch zone 170 into the data configuration module 140 of the touchscreen. When the anti-accidental touch function is enabled later, the data configuration module 140 can directly call this parameter for data masking judgment. After saving, the doctor can exit the division mode in two ways: one is to press the control button briefly to quickly return to the normal usage interface; the other is that no active operation is required, and the system will automatically exit the division mode and save the configuration if no area adjustment operation is detected within a set time (e.g., 3 seconds), avoiding configuration loss due to forgetting to operate. After exiting, the division mode activation indicator and the area boundary visualization indicator on the touchscreen will disappear simultaneously, restoring the normal display state without affecting subsequent explanations or operations. The saved configuration parameters can be reused for a long time. If the doctor needs to adjust the area division due to changes in the explanation content, they can press and hold the control button again to enter the division mode and reset it. The new configuration will automatically overwrite the original parameters, flexibly adapting to the usage needs of different medical scenarios. The entire area division process does not rely on any additional support from the host computer. It is achieved entirely through the collaborative operation of the touch screen's own control module 120 and data configuration module 140, which ensures both operational independence and configuration stability and reusability.

[0037] According to an embodiment of the present invention, the control button is a physical button or a screen virtual button. The physical button is integrated into the edge of the display, and the screen virtual button is displayed in the non-core display area of ​​the touch screen.

[0038] Specifically, both forms of the control buttons are designed around the medical explanation scenario of medical device displays. The goal is to achieve convenient control of the anti-accidental touch function without interfering with the core display content of the screen or increasing the complexity of operation, and to adapt to the structural design of different medical devices and the operating habits of doctors.

[0039] For the physical buttons, their integration into the monitor edge design has been optimized for specific scenarios: the monitor edge is a non-display area, not occupying the main screen space, thus avoiding obstruction of key explanatory content such as lesion images and treatment plan diagrams, ensuring visual continuity for doctors explaining to patients. The physical buttons are preferably installed on the left or right sides or bottom edge of the monitor. These areas allow doctors to easily operate them during explanations, even enabling blind operation without shifting their attention away from the screen content, meeting the fast-paced, high-focus requirements of medical settings. To further improve operational accuracy, the physical buttons can adopt a slightly raised structure with an anti-slip texture, allowing doctors to quickly locate them by touch and avoiding accidental triggering due to hand slippage. Simultaneously, the physical buttons provide clear tactile feedback and moderate pressure, preventing operational failure due to too light a touch and operational inefficiency due to too heavy a press, thus linking with the auxiliary sensing area 110. When the physical button triggers the anti-accidental touch function or the area division mode, the auxiliary sensing area 110 simultaneously issues a visual prompt, allowing doctors to intuitively confirm the operation result.

[0040] For on-screen virtual buttons, their design, displayed in non-core display areas, fully balances visual compatibility and ease of operation. Non-core display areas typically refer to the corners and narrow edges of the screen, where they are less likely to obscure key information. Virtual buttons are designed with a semi-transparent style or light colors, and their size is kept small and easily clickable. This ensures that doctors can quickly locate and operate the buttons without them being too conspicuous and interfering with the viewing of important information on the screen. Clicking a virtual button provides clear interactive feedback, such as a darkening color, a slight flash, or a brief tactile vibration, allowing doctors to immediately confirm that the operation has taken effect and avoid repeated clicks or misoperations. Furthermore, virtual buttons can be flexibly adjusted according to actual usage needs. They can be set to be permanently displayed or automatically hidden when idle. When hidden, they can be woken up by lightly touching the edge of the screen, further reducing interference with the screen display. Their position can also be fine-tuned in the system settings to adapt to different doctors' operating habits, ensuring convenient triggering for both left-handed and right-handed users.

[0041] Both button designs are deeply integrated with the accidental touch prevention function and the 170° anti-touch zone division mode: whether it's a physical or virtual button, a single click directly triggers the accidental touch prevention function, while a long press triggers the zone division mode. The unified operation logic allows doctors to switch between them without additional training. Furthermore, the button designs avoid areas prone to accidental touches. The edge layout of physical buttons and the non-core area layout of virtual buttons reduce the probability of accidental button touches during explanations, forming a closed loop with the overall accidental touch prevention solution to ensure the accuracy and reliability of functional control.

[0042] According to an embodiment of the present invention, the trigger duration of the long press control button is 1-3 seconds. During the long press, the touch screen displays a partition mode activation indicator, indicating that the anti-touch zone 170 setting state has been entered.

[0043] Specifically, the trigger duration for the long press control button is set to 1-3 seconds, a result of precise optimization based on practical needs in medical scenarios. This balances safety against accidental touches with operational efficiency. This duration range effectively distinguishes between "intentional long presses" and "unintentional touches": the lower limit of 1 second prevents accidental triggering due to slight hand slips or brief touches, preventing doctors from inadvertently entering the partitioning mode during explanations; the upper limit of 3 seconds avoids disrupting the operational rhythm due to excessive waiting time, aligning with the fast-paced and high-efficiency characteristics of medical scenarios, allowing doctors to switch modes without prolonged waiting. The trigger duration can be fine-tuned within a preset range, flexibly adapting to different medical device display usage scenarios or doctors' operating habits, further enhancing the solution's compatibility. When the long press time reaches the set threshold, the control module 120 immediately sends a partitioning mode activation signal to the data configuration module 140, simultaneously triggering the subsequent area setting process, ensuring timely operational response.

[0044] The key design feature of the mode activation indicator displayed during the long press is its intuitive presentation without interfering with core operations. The indicator's presentation aligns with the touchscreen's display logic, employing methods such as a cyclical flashing of the screen border, a simple pop-up icon in the corner of the interface, or text prompts at the bottom of the screen. These methods are both eye-catching and easily noticeable, without obscuring lesion images, treatment plan diagrams, or other explanatory content, ensuring doctors can still view key information on the screen during setup. The indicator's visual style is consistent and simple, with colors chosen to have moderate contrast with the screen display content, avoiding distractions due to overly glaring colors or ineffective prompts due to insufficient contrast. Simultaneously, this indicator, along with the auxiliary sensing area 110 on the outer edge of the touchscreen, forms a dual prompting mechanism. The activation indicator is displayed on the screen, while the auxiliary sensing area 110 simultaneously emits a subtle visual signal, allowing doctors to visually confirm successful entry into the anti-touch zone 170 setup state, avoiding operational confusion caused by a single, unclear prompt.

[0045] Regardless of whether the control button is physical or virtual, the long-press trigger duration and the display logic of the start indicator remain consistent. This ensures that doctors can develop a unified operating habit when operating on different types of medical device displays, without needing additional adaptation. The start indicator will remain displayed until the doctor completes the area settings and exits the partitioning mode. If the doctor releases the button but the set duration has not been reached, the indicator will disappear immediately, and the control module 120 will not send a start signal. This prevents accidental entry caused by incomplete long-press operations, further enhancing the accuracy and reliability of the operation, perfectly adapting to the stringent requirements of precision in medical scenarios.

[0046] According to an embodiment of the present invention, the shape of the anti-touch area 170 includes a rectangle, a polygon, or an irregular shape. When customizing the settings, the boundary vertices of the anti-touch area 170 can be determined by touching the screen or the boundary can be dragged to adjust the range.

[0047] Specifically, the anti-touch zone 170 supports diverse shape designs such as rectangles, polygons, and irregular shapes, adapting to different screen display needs and accidental touch areas in medical explanation scenarios, allowing doctors to accurately define the anti-accidental touch range based on the actual explanation content; while the operation method of determining the boundary vertices by touching the screen or dragging the boundary to adjust it takes into account both ease of operation and flexibility of settings, perfectly matching the touch screen usage habits of doctors.

[0048] The rectangular shape is suitable for most common scenarios, especially for regular, easily accidental touch areas such as the edges and corners of the screen. For example, when doctors are explaining something, their hands are often close to the sides or bottom of the screen. They can directly tap the two opposite corners of the screen in the corresponding direction, and the system will automatically generate a rectangular anti-touch zone of 170, quickly covering the area prone to accidental touch. Setting this shape requires no complicated operations and can be completed in one step, adapting to the needs of fast-paced medical scenarios. At the same time, the rectangular boundaries are clear, and subsequent adjustments or reuse are more convenient.

[0049] Polygonal shapes are designed for easily accidental touch areas scattered across the screen, or scenarios requiring precise avoidance of operation points. For example, if a portion of the screen contains parameter adjustment buttons surrounded by multiple easily accidental touch points, the doctor can sequentially click on multiple vertices on the screen to create a polygonal anti-touch zone (170°). This effectively covers all easily accidental touch points while precisely avoiding the core area requiring operation, thus preventing the blocking of effective actions. The number of vertices in the polygon is not fixed and can be flexibly increased or decreased according to actual needs to adapt to complex screen layouts.

[0050] The irregular shape addresses the personalized needs of specific explanation scenarios. For example, when explaining lesion images, the image edges are irregular, and the doctor's hand may move randomly around the image, leading to accidental touches. In this case, continuous tapping of the screen can create an irregular closed area, completely enclosing the area around the image that is prone to accidental touches, without affecting the use of the image itself or surrounding operation buttons. This shape breaks the limitations of regular shapes, allowing the anti-touch zone 170 to perfectly fit the actual usage scenario, achieving a more precise anti-accidental touch effect.

[0051] Both operation methods in the custom settings are simple and intuitive, requiring no additional learning cost. The method of determining boundary vertices by touching the screen is consistent with the logic of regular touchscreen drawing operations. Doctors simply need to tap the screen sequentially as needed to define the range. During the tapping process, the screen displays the selected vertices and temporary boundaries in real time, facilitating timely adjustments. The method of adjusting the range by dragging the boundary is suitable for scenarios requiring fine-tuning after definition. Doctors can long-press the generated boundary line or vertex and drag it to the target position. The system simultaneously updates the anti-touch zone 170° range. During the adjustment process, the boundary changes in real time following hand movements, and the screen visually distinguishes the anti-touch zone 170° from the effective operation zone 160° using light shadows, dotted lines, and other visual methods, allowing doctors to clearly understand the adjustment results.

[0052] The two operation modes can be flexibly switched. Doctors can first define the initial range by determining the vertices, and then fine-tune it by dragging the boundaries to ensure that the anti-touch zone 170 fully meets expectations. The entire setup process does not rely on complex tools or professional operations; it can be completed simply through regular touchscreen interaction, making it suitable for doctors of different ages and operating habits. At the same time, it works in conjunction with the activation indicator of the partitioning mode and the prompt signal of the auxiliary sensing zone 110 to ensure the accuracy of the setup process, further improving the convenience and reliability of use in medical scenarios.

[0053] The present invention also provides a touch screen that prevents accidental touches. Figure 3 This is a block diagram of the anti-accidental touchscreen provided by the present invention. Figure 3 As shown, the anti-mistouch touchscreen 100 provided by the present invention includes: an auxiliary sensing area 110, disposed on the outer edge of the touchscreen, used to assist in identifying the start / stop state of the anti-mistouch function; a control module 120, configured with control buttons, used to support single-click to start / stop the anti-mistouch function and long-press to enter the anti-mistouch area 170 division mode; a data acquisition module 130, used to acquire touch action data of the entire area of ​​the touchscreen; a data configuration module 140, used to pre-store custom configuration parameters of the anti-mistouch area 170, and to block touch data of the anti-mistouch area 170 when the anti-mistouch function is enabled; and a data sending module 150, used to send the valid touch data processed by the data configuration module 140 to the host.

[0054] Specifically, the five components of the anti-accidental touchscreen 100 work together to form a complete workflow from operation triggering, status feedback, data processing to accurate transmission. All module functions are designed around the anti-accidental touch requirements of medical scenarios, without relying on additional configuration of the host, ensuring both ease of operation and operational stability.

[0055] The auxiliary sensing area 110 serves as a visual feedback unit for functional status, employing a ring or strip structure to adapt to different display designs. The ring structure can surround the entire outer edge of the touchscreen, providing comprehensive status indication; the strip structure can be flexibly positioned on the left, right, or bottom edges of the screen, avoiding the occupation of critical display space. This area provides real-time feedback on the anti-mistouch function status. When the anti-mistouch function is activated, it emits a soft visual prompt signal, such as a continuously lit light or a bright screen bezel. The prompt signal uses a low-saturation color scheme, making it both eye-catching and easily noticeable without being glaring or distracting. When the function is deactivated, the prompt signal turns off simultaneously, allowing doctors to quickly confirm the function status visually and avoid misoperation due to unclear status. The auxiliary sensing area 110 is linked to the control module 120. When the control module 120 triggers the anti-mistouch activation / deactivation or area division mode, it simultaneously switches the prompt status, creating an immediate response between operation and feedback.

[0056] The control module 120 is the core of the touchscreen operation, playing a crucial role in function activation / deactivation and mode switching. The module's control buttons support both physical and virtual buttons. Physical buttons are integrated into the edge of the display and feature a raised, anti-slip design for easy blind operation during explanations. Virtual buttons are displayed in non-core areas of the touchscreen and are semi-transparent, ensuring they do not interfere with viewing the core content. The control module 120 operates with highly unified logic. A single button click sends an anti-accidental touch function activation / deactivation signal to the data configuration module 140, enabling rapid function switching. A long press enters the anti-touch zone 170 partition mode. The long press duration is preset to 1-3 seconds and can be flexibly adjusted, preventing accidental triggering with short presses without affecting operational efficiency. During the long press, the control module 120 simultaneously triggers the touchscreen to display a partition mode activation indicator, creating dual feedback with the prompt signal from the auxiliary sensing area 110, ensuring the doctor accurately perceives the operational status.

[0057] The touch area of ​​the touchscreen perfectly matches the display area of ​​the monitor, ensuring precise correspondence between touch operations and screen display. The data acquisition module 130 possesses full-area, high-precision touch data acquisition capabilities, capturing all touch actions on the touchscreen in real time. The acquisition range covers the entire effective display area of ​​the touchscreen, with no blind spots, ensuring no touch actions are missed. Acquired data includes key information such as touch position coordinates and action type, with acquisition accuracy meeting the requirements of medical scenarios, avoiding failure of anti-mistouch judgment due to acquisition errors. This module adopts a real-time acquisition mechanism, immediately capturing data when a touch action occurs and transmitting the raw data to the data configuration module 140 immediately, providing a timely and accurate data source for subsequent shielding judgments, ensuring timely anti-mistouch response, and meeting the fast-paced usage needs of medical scenarios.

[0058] The data configuration module 140 is the key processing unit for the anti-mistouch function, responsible for parameter storage, data comparison, and shielding decision-making. The module pre-stores doctor-defined parameters for the anti-touch zone 170, including its location coordinates, boundaries, and shape. These parameters are stably stored and reusable; new configurations automatically overwrite existing parameters when adjustments are needed. When the anti-mistouch function is enabled, the data configuration module 140 receives raw touch data from the data acquisition module 130, accurately compares the touch location coordinates with the pre-stored anti-touch zone 170 parameters, and quickly determines whether the touch action occurred within the anti-touch zone 170. If the touch data is determined to be within the anti-touch zone 170, the module discards the data without transmitting it to the data sending module 150; if the touch data is determined to be within the valid operation area 160, the data is retained and forwarded to the data sending module 150. The entire process requires no host intervention and is completed autonomously by the touchscreen, ensuring operational independence and stability.

[0059] The data transmission module 150 is responsible for accurately transmitting the touch data processed by the data configuration module 140 to the host, ensuring the accuracy and timeliness of data transmission. When the anti-mistouch function is enabled, the data transmission module 150 only receives and transmits touch data from the valid operation area 160, ensuring that the host only responds to reasonable operations and avoids interface jumps or parameter changes caused by accidental touches. When the anti-mistouch function is disabled, the data transmission module 150 receives and completely transmits the full-area touch data collected by the data acquisition module 130, allowing the host to respond to all operations according to normal logic, meeting the doctor's needs for full-area touchscreen operation. The transmission logic of the data transmission module 150 is closely linked with that of the data configuration module 140, ensuring accurate data transmission in both states and adapting to the stringent requirements of device response reliability in medical scenarios.

[0060] The five modules work together to form an organic whole. From the doctor's operation of the control button to trigger the function, to the feedback status of the auxiliary sensing area 110, and then to data acquisition, configuration processing and precise transmission, no additional configuration is required from the host. This not only adapts to the operating habits of doctors when explaining in medical scenarios, but also ensures the stability and accuracy of the medical device display.

[0061] Figure 4 This is a structural diagram of the anti-accidental touchscreen and its connection to the host computer. (For example...) Figure 4 As shown, the auxiliary sensing area 110 is a ring or strip structure, which is set around the outer edge of the touch screen. When the anti-mistouch function is confirmed to be enabled, the auxiliary sensing area 110 emits a visual prompt signal.

[0062] Specifically, Figure 4 The layout of the anti-accidental touchscreen 100 and its collaborative relationship with the host are presented through a combination of structural and connection diagrams.

[0063] The structural diagram illustrates the external shape and internal area division of the anti-accidental touchscreen 100. The auxiliary sensing area 110 surrounds the outer edge of the touchscreen in a ring or strip structure. The ring structure completely encloses the entire screen, while the strip structure can be flexibly arranged on the left, right, or bottom edges of the screen, without occupying core display space and ensuring no blind spots in status prompts. Inside the screen, the effective operation area 160 and the anti-accidental touch area 170 are clearly distinguished by dotted lines or varying shades of shadow. The clear boundary markings between the two areas allow doctors to intuitively understand the customized division results. If the control buttons of the control module 120 are physical, they will be marked near the auxiliary sensing area 110 at the edge of the display for easy observation of status prompts during operation; if they are virtual, they will be marked in a non-core display area of ​​the touchscreen using a semi-transparent style to avoid interfering with content viewing, always maintaining consistency with the functional positioning of the control module 120.

[0064] The connection diagram illustrates the communication link between the anti-mistouch touchscreen 100 and the host. The anti-mistouch touchscreen 100 establishes a connection with the host through the data transmission module 150. The connection method is compatible with conventional interfaces or wireless transmission protocols, requiring no software configuration or hardware modification to the host. The data transmission process is strictly linked to the functional status: when the anti-mistouch function is enabled, the data transmission module 150 only transmits touch data from the valid operating area 160 to the host, ensuring that the host only responds to reasonable operations; when the anti-mistouch function is disabled, touch data from the entire area is collected by the data acquisition module 130 and then completely transmitted to the host through the data transmission module 150, and the host responds to all operations according to normal logic. The connection diagram uses arrows to indicate the direction of data transmission, clearly showing the transmission logic from the data transmission module 150 of the anti-mistouch touchscreen 100 to the host.

[0065] The visual prompts in the auxiliary sensing area 110 are triggered synchronously with the anti-accidental touch status. When a doctor clicks the control button on the control module 120 to activate the anti-accidental touch function, the auxiliary sensing area 110 immediately emits a soft visual prompt, such as a continuously lit low-saturation light or a slowly cycling highlight on the border. When the function is deactivated, the prompts in the auxiliary sensing area 110 are simultaneously turned off, allowing the doctor to quickly confirm the current status of the anti-accidental touch touchscreen 100 visually, avoiding misoperation due to unclear status. This prompting mechanism, along with the division of the effective operating area 160 and the anti-accidental touch area 170, and the data transmission logic between the data transmission module 150 and the host, forms a closed loop, ensuring that the entire process from operation triggering to status feedback and data transmission is visually presented through clear annotations in the attached diagrams, adapting to the dual requirements of reliability and convenience in medical scenarios.

[0066] According to an embodiment of the present invention, the long press trigger duration of the control module 120 is preset to be 1-3 seconds. During the long press, the control module 120 sends a partitioning mode start signal to the data configuration module 140.

[0067] Specifically, the long-press trigger duration of control module 120 is preset to 1-3 seconds. This range is precisely set based on the practical characteristics of medical scenarios and the need to prevent accidental triggering, ensuring both operational safety and efficiency in the fast-paced medical environment. The lower limit of 1 second effectively filters out unintentional operations such as slight hand swipes and brief touches, preventing doctors from accidentally triggering the partition mode by pressing the control button during explanations. The upper limit of 3 seconds avoids reducing operational smoothness due to excessive waiting time, allowing doctors to quickly enter the anti-touch zone 170 setting state without additional time, meeting the operational convenience requirements of medical scenarios. Furthermore, this duration range can be fine-tuned according to the usage scenarios of different medical device displays or the operating habits of doctors, further improving the adaptability of the solution and ensuring accurate triggering under different usage needs.

[0068] During the long press, the control module 120 and the data configuration module 140 establish real-time communication. When the doctor presses and holds the control button on the control module 120 for a preset duration, the control module 120 immediately generates and sends a partitioning mode activation signal. This signal transmission is delay-free, ensuring that the data configuration module 140 can respond promptly and quickly switch to the anti-touch zone 170 setting state. The activation signal activates the parameter receiving and storage functions of the data configuration module 140, preparing for the doctor to customize the position, range, and shape of the anti-touch zone 170. This allows the data configuration module 140 to capture and store various parameters during the setting process in real time, ensuring the accuracy of the configuration results.

[0069] This interactive logic forms a closed loop with the overall anti-mistouch solution: While the control module 120 sends a start signal, it simultaneously triggers the touchscreen to display a mode-specific start indicator, and the auxiliary sensing area 110 emits a slight visual prompt signal, creating a dual feedback mechanism. This allows doctors to clearly confirm visually that they have successfully entered the setting state, avoiding operational confusion caused by unclear signal transmission or status feedback. Regardless of whether the control buttons on the control module 120 are physical or virtual, the long-press trigger duration and start signal sending logic remain consistent, ensuring that doctors can develop a unified operating habit when operating on different types of anti-mistouch touchscreens 100 without additional adaptation. The entire process requires no host intervention, relying entirely on the autonomous collaboration of the control module 120 and the data configuration module 140. This ensures both operational independence and the stability and reliability of the anti-mistouch area 170 setting process, perfectly adapting to the dual requirements of medical scenarios for device operation accuracy and stability.

[0070] According to an embodiment of the present invention, the shielding logic of the data configuration module 140 is as follows: the collected touch data is compared with the pre-stored anti-touch zone 170 parameters, and when it is confirmed that the touch position is located in the anti-touch zone 170, the touch data is discarded and not transmitted to the data sending module 150.

[0071] Specifically, the shielding logic of the data configuration module 140 revolves around comparison and judgment and data discarding. It executes autonomously throughout the process with immediate response, adapting to the precision requirements of medical scenarios for preventing accidental touches. Once the accidental touch prevention function is enabled, this logic starts, and the data configuration module 140 continuously receives touch data from the data acquisition module 130 covering the entire touchscreen area. This data includes key information such as touch location coordinates and action type. Simultaneously, the module pre-stores parameters for the doctor-defined anti-touch zone 170, covering configuration content such as location information, boundary range, and shape type. These parameters are stored stably, and new configurations automatically overwrite the original content upon subsequent resets.

[0072] The comparison process is efficient and accurate. The data configuration module 140 matches the real-time received touch position coordinates with the pre-stored anti-touch zone 170 parameters point by point. Regardless of whether the anti-touch zone 170 is a rectangle, polygon, or irregular shape, the module can quickly determine the location of the touch position using parameters such as boundary vertices and range thresholds. Once it is confirmed that the touch position is within the anti-touch zone 170, the module immediately identifies and discards the touch data, and no longer transmits any related information to the data sending module 150.

[0073] This logic ensures the directness and thoroughness of the anti-accidental touch effect from the root. Discarded data cannot enter the subsequent transmission process, and the host will not generate any response because it has not received the touch data, effectively avoiding misoperation caused by accidental hand touch or electrical interference during the doctor's explanation. The entire comparison, judgment and discarding process does not require the host's participation, but is completed autonomously by the data configuration module 140. The response speed is fast and there is no delay, which not only ensures the accuracy of operation, but also does not affect the normal smoothness of touch screen use, forming an efficient and collaborative working closed loop with components such as the control module 120 and the data acquisition module 130.

[0074] According to an embodiment of the present invention, if the anti-accidental touch function is confirmed to be off, the data configuration module 140 does not perform a shielding operation, and the full-area touch data collected by the data acquisition module 130 is completely transmitted to the host via the data transmission module 150, and the host responds according to the normal logic.

[0075] Specifically, the anti-accidental touch function is disabled by the doctor clicking the control button on the control module 120. After the operation is triggered, the visual prompt signal on the auxiliary sensing area 110 is simultaneously turned off, intuitively informing the doctor that the anti-accidental touch state has been exited without any additional confirmation steps. At this time, the data configuration module 140 stops performing any data shielding operations. Although the previously stored parameters of the anti-touch area 170 are still retained for later reuse, they no longer participate in data judgment, ensuring that all touch data can flow normally.

[0076] The data acquisition module 130 maintains full-area, high-precision acquisition, continuously capturing all touch actions on the effective operating area 160 and the original anti-touch area 170 of the touchscreen. The acquired content includes key information such as touch position coordinates and action type, with no blind spots or data omissions. The acquisition accuracy always meets the usage requirements of medical scenarios. This full amount of raw data is transmitted to the data configuration module 140 in real time. Since the shielding logic is not activated, the data configuration module 140 does not filter or discard the data and directly forwards it completely to the data sending module 150.

[0077] After receiving the full-area touch data forwarded by the data configuration module 140, the data transmission module 150 transmits the data completely to the host according to the conventional transmission logic. The transmission process is delay-free and data loss-free, ensuring that the host can obtain all touch information. After receiving the data, the host responds according to the conventional logic. Regardless of the type of touch action, such as clicking or swiping, and regardless of where it occurs on the touchscreen, timely and accurate feedback is provided. This meets the full-function usage needs of doctors in routine operating scenarios. For example, operations such as parameter adjustment, interface switching, and file retrieval can all be completed smoothly without affecting the normal operation of the medical device display. It also allows for flexible switching between the anti-accidental touch state and the active state, fully adapting to the diverse usage needs of medical scenarios.

[0078] The present invention provides an anti-accidental touchscreen and anti-misoperation method that, through module collaboration and process optimization, constructs a complete anti-accidental touch solution adapted to medical scenarios. From customizable area division to flexible function start / stop, from precise data shielding to full data transmission switching, all designs revolve around ease of operation, accurate anti-accidental touch, and device compatibility. It can operate stably without additional host configuration, solving the pain points of misjudgment and compatibility in existing solutions, and fully meeting the diverse needs of doctors' explanations and routine operations, providing reliable protection for the touchscreen use of medical device displays.
