Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ultrasound device and an ultrasound system. Background Technology

[0002] Medical ultrasound equipment must be used in conjunction with an ultrasound workstation. The ultrasound system consists of the workstation and the equipment, which work together to examine and diagnose patients. The doctor uses the ultrasound equipment to perform the examination and the workstation to complete the report. However, the ultrasound equipment and the workstation are two relatively independent systems. Without an assistant, if the doctor needs to review the patient's medical history during an ultrasound examination, they must move from the ultrasound equipment to the workstation to operate and review the information. After the examination, the doctor must return to the workstation to compile and write the report, switching between the two systems again.

[0003] Such switching operations increase the complexity of the doctor's work and can also affect the patient's trust in the doctor. Copying data from the ultrasound workstation to the ultrasound device raises concerns about compatibility with the device's functions and could also lead to information insecurity due to confidentiality issues. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, an ultrasound device is provided, including an ultrasound host and an ultrasound display. The ultrasound device further includes a signal control module, which includes a first signal input interface connected to the ultrasound host, a second signal input interface for connecting to an external signal device, and a first signal output interface connected to the ultrasound display. The signal control module is configured to select the first signal input interface to connect to the first signal output interface in a first mode, and to select the second signal input interface to connect to the first signal output interface in a second mode.

[0005] For example, the ultrasound device further includes a first external input device, and the signal control module further includes: a first control input interface connected to the first external input device; a first control output interface connected to the ultrasound host; and a second control output interface for connecting to an external signal device. The signal control module is further configured to: select the first control output interface to connect to the first control input interface in a first mode; and select the second control output interface to connect to the first control input interface in a second mode.

[0006] For example, the signal control module is configured to select, in the third mode, both the first signal input interface and the second signal input interface are connected to the first signal output interface, and to select, either the first control output interface or the second control output interface is connected to the first control input interface.

[0007] For example, the signal control module is configured to select, in the third mode, both the first signal input interface and the second signal input interface to be connected to the first signal output interface.

[0008] For example, the first external input device includes one or more of a mouse, keyboard, trackball, and touch control device.

[0009] For example, the first external input device includes a touch control device disposed on the ultrasonic display.

[0010] For example, the touch control device is an infrared touch control device.

[0011] For example, the first signal input interface and the first control output interface are constructed as two parts of the same interface.

[0012] For example, the second signal input interface and the second control output interface are constructed as two parts of the same interface.

[0013] For example, the ultrasound device also includes an additional display, and the signal control module also includes a second signal output interface connected to the additional display. The signal control module is also configured to select a corresponding interface of the first signal input interface and the second signal input interface to connect to the second signal output interface in different modes.

[0014] For example, the ultrasound device further includes a second external input device, and the signal control module further includes a second control input interface connected to the second external input device; the signal control module is also configured to: when only the first signal input interface is connected to the second signal output interface, select the first control output interface to connect to the second control input interface; when only the second signal input interface is connected to the second signal output interface, select the second control output interface to connect to the second control input interface.

[0015] For example, the signal control module is further configured such that when both the first signal input interface and the second signal input interface are connected to the second signal output interface, the first control output interface and the second control output interface are selectively connected to the second control input interface.

[0016] For example, an additional display and a second external input device are configured together as a touch screen.

[0017] For example, the signal control module includes a toggle switch configured to enable selective connectivity between interfaces.

[0018] For example, the ultrasound device has a control panel, and a switch is set on the control panel.

[0019] According to another aspect of this application, an ultrasound system is provided, including the ultrasound device described above. The ultrasound system includes an external signal device connected to a second signal input interface.

[0020] For example, the external signal device includes a computer host.

[0021] For example, the ultrasound system also includes an image storage device for storing images generated by the ultrasound host, the signal input interface of the image storage device being connected to the ultrasound host, and the signal output interface of the image storage device being connected to an external signal device.

[0022] For example, the image storage device includes an image acquisition card, and the external signal device also includes a computer host, with the image acquisition card connected to the computer host.

[0023] For example, the image storage device includes an activation switch, and the ultrasound device has a control panel on which the activation switch is located.

[0024] In the above technical solution, the signal control module allows the ultrasound monitor to view information from both the ultrasound host and the ultrasound workstation. This enables doctors to remain at the location of the ultrasound equipment throughout the examination, facilitating convenient review of the patient's medical history. While achieving these functions, it eliminates the need to import internal information from the ultrasound workstation into the ultrasound host, ensuring information security. Furthermore, doctors can easily control the displayed information on the ultrasound monitor with simple operation, requiring no learning of operating procedures and allowing for adjustments based on personal preferences, resulting in a superior user experience.

Detailed Implementation

[0035] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0036] like Figure 1 As shown, this application provides an ultrasound device. Typically, the ultrasound device includes an ultrasound host 23 and an ultrasound display 21. The ultrasound host 23 can acquire ultrasound information through a connected ultrasound probe (not shown), and obtain real-time ultrasound images after processing. The ultrasound display 21 can display various images, such as the ultrasound images described above. The images can include static images, such as photographs, dynamic images, such as videos, or both. The ultrasound device may also include a signal control module. The signal control module can be located inside the ultrasound device, for example, below the control panel 3. Figure 3 and Figure 4As shown, the signal control module 1 may include a first signal input interface 122 connected to the ultrasound host 23, a second signal input interface 123 for connecting to an external signal device 22, and a first signal output interface 121 connected to the ultrasound display 21. The first signal input interface 122, the second signal input interface 123, and the first signal output interface 121 may include analog signal interfaces such as VGA or S-Video, or digital signal interfaces such as HDMI or DP. The external signal device 22 may include any device capable of outputting signals such as images; for ease of understanding, it will be referred to as such below. Figure 1 The computer host 51 inside the ultrasound workstation 5 is described in detail as an example of the external signal device 22. Typically, the ultrasound workstation 5 is also equipped with a computer monitor 52, which can display signals such as images transmitted by the computer host 51.

[0037] For example, the signal control module 1 can be constructed using electronic components such as comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0038] The signal control module 1 is configured to select the first signal input interface 122 to connect to the first signal output interface 121 in a first mode, and to select the second signal input interface 123 to connect to the first signal output interface 121 in a second mode. The signal control module 1 can operate in either the first mode or the second mode.

[0039] Reference Figure 1 and Figure 2For ultrasound equipment including signal control module 1, doctors can perform preparatory work before starting a diagnosis using the ultrasound equipment. This preparation may include opening necessary data, such as medical history information, in the ultrasound workstation 5 beforehand. After completing the preparation, the examination can begin at the ultrasound equipment. During the examination, signal control module 1 can be in a first mode, with the first signal input interface 122 connected to the first signal output interface 121. The image signal from the ultrasound host 23 can be transmitted sequentially through the first signal input interface 122 and the first signal output interface 121 of signal control module 1 to the ultrasound display 21 connected to the first signal output interface 121. This allows doctors to view ultrasound images in real time on the ultrasound display 21, just as with existing ultrasound equipment. Optionally, the signals transmitted from the ultrasound host 23 to the ultrasound display 21 sequentially through the first signal input interface 122 and the first signal output interface 121 may also include non-image signals, such as measurement information obtained from images, annotation information, medical record data, etc. Doctors can adjust the operating mode of signal control module 1 using any suitable method, such as a power switch, remote control, pedal, timer, or keyboard combination keys. When the signal control module 1 is in the second mode, and the signal control module 1 selects the second signal input interface 123 to connect to the first signal output interface 121, the image signal of the ultrasound workstation 5 can be transmitted sequentially through the second signal input interface 123 and the first signal output interface 121 to the ultrasound display 21 for display. Optionally, the signal transmitted from the ultrasound workstation 5 to the ultrasound display 21 sequentially through the second signal input interface 123 and the first signal output interface 121 may also include non-image signals, such as one or more of measurement information, annotation information, and medical records obtained from images. This allows doctors to view information from the ultrasound workstation 5 through the ultrasound display 21 when they need to access the data from the ultrasound workstation 5. The image transmitted from the ultrasound workstation 5 to the second signal input interface 123 can be exactly the same as the image displayed on the computer monitor 52 within the ultrasound workstation 5. Specifically, for example, the ultrasound workstation 5 can display the computer desktop on the computer monitor 52 and synchronously output the computer desktop to the second signal input interface 123. The image transmitted from the ultrasound workstation 5 to the second signal input interface 123 for display on the ultrasound monitor 21 can be different from the image displayed on the computer monitor 52 within the ultrasound workstation 5. The ultrasound workstation 5 can display the computer desktop on the computer monitor 52, simultaneously generate an extended desktop parallel to the computer desktop, and output the extended desktop to the second signal input interface 123. For example... Figure 4In the illustrated embodiment, the signal control module 1 may include a first switching switch 1111, which is connected to the signal control module 1 via a switching switch connection line 111. The first switching switch 1111 can switch between signals by turning on and off the transistor array inside the chip. The first switching switch 1111 can connect the first signal input interface 122 to the first signal output interface 121, or connect the second signal input interface 123 to the first signal output interface 121.

[0040] In the above technical solution, through the signal control module 1, information from the ultrasound host 23 and information from the ultrasound workstation 5 can be viewed on the ultrasound display 21, allowing the doctor to remain at the location of the ultrasound equipment during the examination and conveniently review the patient's medical history. While achieving the above functions, it is not necessary to import the internal information of the ultrasound workstation 5 into the ultrasound host 23, ensuring information security. Furthermore, doctors can easily control the information displayed on the ultrasound display 21 with simple operation, without needing to learn the operating methods, and can adjust it according to their own habits, resulting in a good user experience.

[0041] In some embodiments, the signal control module 1 may also have a third mode, in which the first signal input interface 122 and the second signal input interface 123 can be simultaneously connected to the first signal output interface 121. Taking the signal from the ultrasound workstation 5 including medical history information as an example, in this case, the ultrasound image from the ultrasound host 23 and the medical history information from the ultrasound workstation 5 can be simultaneously displayed on the ultrasound display 21 using the dual-screen display function (PBP). Specifically, for example, the ultrasound image obtained in real time can be displayed on the left half of the ultrasound display 21, and the medical history information can be displayed on the right half of the ultrasound display 21, thereby allowing for real-time comparison of the development of the condition, the effect of treatment, etc. For the signal control module in some embodiments, doctors can adjust the position and size ratio of the two screens according to their habits to achieve the best diagnostic effect and user experience. Figure 5As shown, the ultrasound host can output a signal of a first image (see upper left figure) including a functional area, an ultrasound image area, and an image storage area. The ultrasound workstation can output a signal of a second image (see upper right figure) including medical records and blank areas on both sides. The signal control module can extract a portion of the first image output by the ultrasound host, such as the ultrasound image displayed in the ultrasound image area, and display it on the left half of the ultrasound monitor. Simultaneously, it can extract a portion of the second image output by the ultrasound workstation, such as only the medical records, and display it on the right half of the screen (see lower figure). That is, in some embodiments, the signal control module can output a portion of the image to the ultrasound monitor, instead of outputting the received image to the ultrasound monitor unchanged. In other embodiments, the ultrasound workstation can transmit a portion of its displayed second image to the signal control module, which then directly transmits this portion of the image to the ultrasound monitor. Similarly, the ultrasound host can also transmit a portion of its displayed first image to the signal control module, which then directly transmits this portion of the image to the ultrasound monitor.

[0042] Ultrasound images from the ultrasound host 23 and medical history information from the ultrasound workstation 5 can also be simultaneously displayed on the ultrasound monitor 21 via a picture-in-picture (PIP) function. For example, the real-time ultrasound image can be used as the main screen, while the medical history information can be displayed in a small window. In some embodiments, the signal control module 1 allows doctors to adjust the position and size of the small window according to their preferences. Alternatively, the medical history information can be used as the main screen, while the real-time ultrasound image is displayed in a small window. The PBP and PIP functions can be... Figure 5 Use the knob shown to switch.

[0043] For example, the ultrasound device may further include a first external input device. The signal control module 1 may also include a first control input interface 131, which is connected to the first external input device. Figure 2 As shown, exemplarily, the first external input device may include one or more of a mouse, keyboard 32, trackball 31, and touch control device. Using a mouse and keyboard 32 to complete tasks such as writing examination reports is more convenient. For abnormal areas in the examination images, the trackball 31 provides more precise annotation. The touch control device allows doctors to directly annotate on the screen, which is more intuitive and faster. Ultrasound equipment can be configured with one or more first external input devices according to daily usage scenarios to meet different needs. Exemplarily, the first control input interface 131 may include a USB interface, PS / 2 interface, etc., and may have one or more interfaces. In cases where the first control input interface includes multiple interfaces, such as... Figure 2As shown, the trackball 31 and keyboard 32 can be simultaneously connected to the signal control module 1. The trackball 31 and keyboard 32 can also be mounted together on the control panel of the ultrasound device. Even when the first control input interface 131 includes only one interface, this application does not exclude embodiments in which multiple first external input devices are connected to the first control input interface 131 via a USB hub.

[0044] The signal control module 1 may further include a first control output interface 134 and a second control output interface 133. The first control output interface 134 is connected to the ultrasound host 23, and the second control output interface 133 is used to connect to an external signal device 22. In some embodiments, the interface forms of the first control output interface 134 and the second control output interface 133 may be the same as those of the first control input interface 131. For example, the first control input interface 131 is connected to a first external input device of type USB, and the first control output interface 134 and the second control output interface 133 may also be connected to the USB interfaces of the ultrasound host 23 and the ultrasound workstation 5 respectively via cables. In other embodiments, the interface forms of the first control output interface 134 and the second control output interface 133 may be different from those of the first control input interface 131. For example, the first control input interface 131 is connected to a first external input device of type USB, and one or both of the first control output interface 134 and the second control output interface 133 correspond to the PS / 2 interfaces of the ultrasound host 23 and the ultrasound workstation 5, or vice versa. In summary, the first external input device can control either the connected ultrasound host 23 or the ultrasound workstation 5 via the signal control module 1. (Continue to refer to...) Figure 4 The signal control module 1 may include a second switching switch 1112. The second switching switch 1112 can also achieve switching through the on and off states of the transistor array inside the chip. The second switching switch 1112 can connect the first control input interface 131 to the first control output interface 134, or connect the first control input interface 131 to the second control output interface 133.

[0045] The signal control module 1 is also configured such that, in the first mode (i.e., when the first signal input interface 122 is connected to the first signal output interface 121), the first control output interface 134 is selected to connect to the first control input interface 131. It is easy to understand that when operating the ultrasound host 23, the doctor needs to confirm whether their operation has been correctly executed based on the image feedback from the ultrasound host 23. If the second signal input interface 123 is connected to the first signal output interface 121, that is, the ultrasound monitor 21 does not display an image from the ultrasound host 23 but displays an image from the ultrasound workstation 5, controlling the ultrasound host 23 may result in clicking the wrong icon or entering the wrong character. Similarly, in the second mode (i.e., when the second signal input interface 123 is connected to the first signal output interface 121), the second control output interface 133 is selected to connect to the first control input interface 131. This allows the doctor to operate either the ultrasound host 23 or the ultrasound workstation 5 through the ultrasound monitor 21 and the first external input device, just like using the ultrasound host 23 or the ultrasound workstation 5 normally, without needing to move between the two devices, and allowing real-time operation without preparation.

[0046] In the third mode (i.e., when both the first signal input interface 122 and the second signal input interface 123 are connected to the first signal output interface 121), the first control output interface 134 and the second control output interface 133 are selectively connected to the first control input interface 131. Since the software interfaces and shortcut key configurations of the ultrasound host 23 and the ultrasound workstation 5 may differ, controlling both simultaneously may lead to unexpected malfunctions. Selectively connecting the first external input device to either the ultrasound host 23 or the ultrasound workstation 5 allows for separate, non-interfering control of both, resulting in a better user experience.

[0047] Exemplarily, when the first external input device includes a touch control device, the touch control device can be located on the ultrasound display 21. In some embodiments, the ultrasound display 21 has built-in touch functionality, which is implemented by the touch control device on the ultrasound display 21. In this case, the touch control device on the ultrasound display 21 can be reused as the first external input device, enabling it to control the ultrasound workstation 5 via the signal control module 1. This reduces the number of first external input devices. In some embodiments, the touch control device on the ultrasound display 21 can also be used to switch the signal control module between a first mode and a second mode. For example, a switching control icon can be displayed on the ultrasound display 21, and when the touch control device is clicked at the location corresponding to the switching control icon, the signal control module can switch between the first mode and the second mode. In other embodiments, as described above, the ultrasound display 21 may be a regular computer monitor without touch control functionality. In this case, an additional touch control device can be added to achieve touch control functionality. This improves the ease of operation. Touch control devices include, but are not limited to, resistive touchscreens, capacitive touchscreens, and infrared touch frames.

[0048] For example, the touch control device can be an infrared touch control device. In this way, the infrared touch function is implemented by an infrared emitting and receiving frame positioned around the ultrasonic display 21 and above the screen. The infrared touch control device does not obstruct the native ultrasonic display 21. Taking an infrared frame touchscreen as an example, when a finger or other object touches the screen, it will block the infrared light. The processor of the infrared touch frame recognizes the input signal, such as single click, double click, stretch, rotate, long press, etc., based on information such as the position, movement, speed, time, and frequency of the infrared obstruction. Compared with other overlay touchscreens (such as the capacitive and resistive touchscreens mentioned above), infrared frame touchscreens can avoid the impact of the touchscreen on the display image quality. Furthermore, the hardware cost of infrared frame touchscreens is lower, and the maintenance cost is relatively low because the touch device is not highly integrated with the display.

[0049] For example, the first signal input interface 122 and the first control output interface 134 are constructed as two parts of the same interface. Specifically, the ultrasound host 23 may employ an interface that supports simultaneous transmission of image and control signals, such as a Thunderbolt interface. The first signal input interface 122 and the first control output interface 134 can also be formally integrated into the same interface, for example, using a dedicated cable. This dedicated cable includes a connector for the signal control module 1, with the middle section being a single strand, and only the ends connecting to the signal and control interfaces of the ultrasound host 23, respectively. Alternatively, the first signal input interface 122 and the first control output interface 134 may not be physical interfaces, but rather connected to the ultrasound host 23 wirelessly. In short, this reduces the number of cables connecting the signal control module 1 to the ultrasound host 23, instead of having the first signal input interface 122 and the first control output interface 134 connected between the signal control module 1 and the ultrasound host 23 via separate cables. This effectively avoids excessive cable tangling and reduces cable management difficulty.

[0050] By way of example, the second signal input interface 123 and the second control output interface 133 can also be constructed as two parts of the same interface. (Refer to reference...) Figure 1 and Figure 2 The cable 222 includes a connector for connecting to the ultrasonic workstation 5. The middle portion of the cable 222 can be a single strand, separating at the connection point 221, and can be connected to the second signal input interface 123 and the second control output interface 133 respectively. It has the same technical effect as the above-described technical solution that constructs the first signal input interface 122 and the first control output interface 134 as the same interface, and will not be described again here.

[0051] Exemplarily, the ultrasound device may also include an additional display 4, see [link to documentation]. Figure 1The ultrasound display 21 is mainly used to display ultrasound images generated by the ultrasound host 23. The auxiliary display 4 usually serves as a display for the lower-level machine, used to display equipment parameters, current information, etc., of the ultrasound equipment. The signal control module 1 may also include a second signal output interface, which is connected to the auxiliary display 4. The signal control module 1 may also be configured to select a corresponding interface from the first signal input interface 122 and the second signal input interface 123 to connect to the second signal output interface in different modes. For example, the signal control module 1 may have two or three of the following three modes: 1. Selecting the first signal input interface 122 to connect to the second signal output interface; 2. Selecting the second signal input interface 123 to connect to the second signal output interface; 3. Selecting both the first signal input interface 122 and the second signal input interface 123 to connect to the second signal output interface simultaneously. The auxiliary display 4 may display synchronously with the ultrasound display 21 or asynchronously. In different modes, the auxiliary display 4 displays different images, which facilitates doctors in viewing medical records and current ultrasound images. It can also achieve real-time comparison through PBP and PIP modes, which will not be elaborated further here. Unlike the ultrasound monitor 21, the auxiliary monitor 4 is typically positioned relatively low, and in some embodiments, it is detachable and movable. Compared to the non-detachable and higher-positioned ultrasound monitor 21, in certain usage scenarios, the operator is in a lower position, requiring them to tilt their head back to operate the ultrasound probe and view the ultrasound monitor 21 simultaneously, which is inconvenient and may limit their field of vision. Displaying information via the auxiliary monitor 4 effectively meets this need. Furthermore, medical record information and the current ultrasound image can be displayed on both the ultrasound monitor 21 and the auxiliary monitor 4, ensuring that both the image size and the current ultrasound image are adequate for real-time comparison.

[0052] Exemplarily, the ultrasound device may further include a second external input device, and the signal control module 1 further includes a second control input interface connected to the second external input device. As described above, the additional display 4 typically serves as a display for the lower-level machine and can also be used to display controls of the ultrasound device, including buttons, scroll bars, etc. The functions of the controls may include mode switching, region of interest (ROI), etc. Therefore, a second external input device is typically configured. The second external input device may include a small input device such as a keypad. The signal control module 1 is also configured such that: when only the first signal input interface 122 is connected to the second signal output interface, the first control output interface is selected to connect to the second control input interface 134; and when only the second signal input interface 123 is connected to the second signal output interface, the second control output interface is selected to connect to the second control input interface 133. Optionally, when both the first signal input interface 122 and the second signal input interface 123 are connected to the second signal output interface, the signal control module 1 may select either the first control output interface 134 or the second control output interface 133 to connect to the second control input interface 131. In other words, the cooperation relationship between the second external input device and the auxiliary display 4 has the same logic as the cooperation relationship between the first external input device and the ultrasound display 21. That is, the second external input device can control the ultrasound host 23 when the auxiliary display 4 displays an image from the ultrasound host 23, or control the ultrasound workstation 5 when the auxiliary display 4 displays an image from the ultrasound workstation 5, or choose to control one of them when both images are displayed at the same time.

[0053] For example, the additional display 4 and the second external input device can be configured as a touch screen. The controls on the additional display 4 are most conveniently operated via touch, and this is a widely used technical solution in current ultrasound equipment. By using the touch screen as the second input device, not only is it easier to operate the ultrasound equipment, but it can also be used to view medical records and current ultrasound images, offering richer functionality and greater flexibility.

[0054] For example, the signal control module 1 may include a switch 11, which is configured to enable selective communication between interfaces. Switching via the switch 11 presents virtually no barrier to entry. Furthermore, the switch 11 can be configured in various forms, such as a pedal switch or a touch switch. For example, the ultrasound device has a control panel 3, and the switch 11 is mounted on the control panel 3. This unified arrangement of various control switches on the control panel 3 facilitates operation. Since the models and specifications of the various control switches are similar, placing the switch 11, whose model and specifications are similar to other control switches, here does not appear abrupt, increases the overall integrity of the device, and avoids accidental activation.

[0055] This application also provides an ultrasound system, which may include any of the ultrasound devices described above. The ultrasound system may also include an external signal device 22. The external signal device 22 may include the ultrasound workstation 5 described above, or other suitable devices capable of outputting signals including images. Exemplarily, the external signal device 22 includes a computer host. Taking the ultrasound workstation 5 described above as an example of the external signal device 22, the ultrasound workstation 5 typically uses a computer, enabling functions such as writing and printing examination reports and calling numbers, and has good compatibility.

[0056] For example, the ultrasound system may further include an image storage device for storing images generated by the ultrasound host 23. The signal input interface of the image storage device is connected to the ultrasound host 23, and the signal output interface of the image storage device is used to connect to an external signal device 22. As mentioned above, storing the patient's ultrasound images in the ultrasound host 23 may pose information security issues. Furthermore, the ultrasound host 23 may not have the function of storing ultrasound images. Therefore, to facilitate the generation of medical record information and the import of new ultrasound images into the medical record system of the ultrasound workstation 5, images generated by the ultrasound host 23 can be obtained through the image storage device connected to the ultrasound workstation, including original images, videos, or images with body markers. The image storage device can always be connected to the ultrasound host 23 without going through the signal control module 1. In some embodiments, the image storage device can complete the image storage work simultaneously with body marker confirmation, reducing the doctor's workload.

[0057] For example, the image storage device may include an image acquisition card, and the external signal device 22 may also include a computer host, with the image acquisition card connected to the computer host. The image acquisition card may include a USB image acquisition card, a PCIe interface image acquisition card, etc. Taking the commonly used PCIe interface image acquisition card as an example, it can be installed inside the computer host chassis, is not easily lost, has rich functionality, and has stronger acquisition performance.

[0058] For example, the image storage device may include an activation switch, which may be set on the control panel 3. Figure 1 The activation switch allows doctors to activate or deactivate image storage as needed, reducing the space occupied by stored images. The activation switch can be connected to the image storage device via wired or wireless means. In some embodiments, doctors can save the current image when the activation switch is pressed, or start recording video after pressing the activation switch. Placing the activation switch on control panel 3 is also unobtrusive and reduces the risk of accidental activation. In some embodiments, the activation switch can work with ultrasound equipment to automatically save images after body marker labeling, preventing doctors from forgetting to save images and simplifying operation.

[0059] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0060] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0061] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0062] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.
