Abstract

A portable ultrasonic imaging device comprises an ultrasonic host, the ultrasonic host comprising a first ultrasonic imaging module, a first energy storage module and a first energy storage management module. The first energy storage management module can control the ultrasonic host to charge the terminal device or the terminal device to charge the ultrasonic host to balance the remaining endurance time between the ultrasonic host and the terminal device. When the remaining endurance time of the ultrasonic host and the terminal device is inconsistent, the power of the party with higher remaining endurance time can be transmitted to the party with lower remaining endurance time, so that the remaining endurance time of both parties is greater than the minimum remaining endurance time of the initial party, thereby improving the endurance time of the portable ultrasonic imaging device and the terminal device in connection. The first ultrasonic image data is sent to the terminal device and displayed through the display module of the terminal device. The portable ultrasonic imaging device does not include a display module and other components, which is conducive to reducing the size of the portable ultrasonic imaging device.

[0001] This invention relates to the field of medical device technology, specifically to a portable ultrasound imaging device. Background Technology

[0002] Traditional ultrasound equipment mainly includes two types: desktop ultrasound equipment and portable ultrasound equipment. Desktop ultrasound equipment is large in size, has high imaging quality, and is suitable for fixed use locations, while portable ultrasound equipment is similar in shape to a laptop computer, is smaller in size, and can be more easily moved to other locations for use.

[0003] However, portable ultrasound devices are still relatively large and inconvenient to carry around. Furthermore, miniaturization of ultrasound devices limits their battery life, affecting the user experience. Summary of the Invention

[0004] This invention provides a portable ultrasound imaging device to solve the problems of large size and short battery life of ultrasound devices.

[0005] In one embodiment, a portable ultrasound imaging device is provided, comprising:

[0006] An ultrasound host is used to connect to an ultrasound probe and receive ultrasound echo signals sent by the ultrasound probe. The ultrasound host includes a first ultrasound imaging module, a first energy storage module, and a first energy storage management module.

The first ultrasound imaging module generates first ultrasound image data based on the ultrasound echo signals and sends the first ultrasound image data to a terminal device.

[0023] In one embodiment, the system further includes the ultrasonic probe, which is used to emit ultrasonic waves toward the imaging target and receive ultrasonic echo signals returned by the imaging target.

[0024] In one embodiment, the terminal device is also included.

[0025] The terminal device includes a second energy storage module and a display module. The display module is connected to the second energy storage module and is used to display the first ultrasound image data.

[0026] When the terminal device is connected to the ultrasound host, the first energy storage management module is used to control the first energy storage module to release electrical energy to the second energy storage module; and / or control the second energy storage module to release electrical energy to the first energy storage module.

[0027] In one embodiment, a portable ultrasound imaging device is provided, comprising:

[0028] An ultrasound host is used to connect to an ultrasound probe and receive ultrasound echo signals sent by the ultrasound probe. The ultrasound host includes a first ultrasound imaging module and a first energy storage module. The first ultrasound imaging module is connected to the first energy storage module. The first ultrasound imaging module generates first ultrasound image data based on the ultrasound echo signals.

[0029] A terminal device is used to connect to the ultrasound host. The terminal device includes a second energy storage module, a second energy storage management module, and a display module. The display module is connected to the second energy storage module and / or the second energy storage management module. The display module is used to display the first ultrasound image data sent by the ultrasound host.

[0030] When the terminal device is connected to the ultrasound host, the second energy storage management module is used to control the second energy storage module to release electrical energy to the first energy storage module, or to control the first energy storage module to release electrical energy to the second energy storage module, so as to balance the remaining battery life between the ultrasound host and the terminal device.

[0031] In one embodiment, a portable ultrasound imaging device is provided, comprising:

[0032] An ultrasonic probe is used to emit ultrasonic waves toward an imaging target and receive ultrasonic echo signals returned by the imaging target. The ultrasonic probe is used to connect to the ultrasonic host and send the ultrasonic echo signals to the ultrasonic host.

[0054] To achieve greater portability, portable ultrasound imaging devices are designed as handheld terminal products. These devices strip away modules such as displays and control panels, retaining only basic functions like power storage, ultrasound imaging, and communication. Therefore, portable ultrasound imaging devices need to be connected to terminal devices with display capabilities (such as mobile phones, tablets, and traditional ultrasound equipment with displays) to achieve complete ultrasound imaging.

[0055] Portable ultrasound imaging devices can be connected to different terminal devices to achieve ultrasound imaging. Portable ultrasound imaging and terminal devices have relatively independent power supply modules, resulting in different remaining battery life between them. Since the two need to work together, the lower remaining battery life in portable ultrasound imaging and terminal devices determines the usage time of ultrasound imaging.

[0056] Therefore, in this embodiment, the portable ultrasound imaging and terminal devices, which have independent power supplies, are configured to be able to charge and discharge each other. An energy storage management module is included in the portable ultrasound imaging device. This module can control the portable ultrasound imaging device to charge the terminal device, or control the terminal device to charge the portable ultrasound imaging device, thereby balancing the remaining battery life between the two devices and ultimately increasing the usage time of ultrasound imaging.

[0057] Of course, by incorporating an energy storage management module within the terminal device, it can also control the portable ultrasound imaging device to charge the terminal device, or vice versa, thus balancing the remaining battery life between the two. Alternatively, the energy storage management modules within both the portable ultrasound imaging device and the terminal device can work together to control mutual charging between them, also achieving a balance in their remaining battery life.

[0058] During the charging process, especially during wireless charging, the frequency used for power transmission of portable ultrasound imaging devices overlaps with the frequency range of the echoes received during ultrasound imaging. This causes electromagnetic interference to the echo signals during charging, resulting in a decrease in the image performance of ultrasound imaging.

[0059] In this embodiment, three solutions are provided to eliminate electromagnetic interference from charging on the echo signal, as follows:

[0060] The first method is to eliminate interference through physical isolation. The charging module and the echo receiving module are placed relatively far apart inside the ultrasound host. For example, the charging module and the echo receiving module are placed at opposite ends of the ultrasound host to increase the distance between them, thereby reducing or avoiding electromagnetic interference between the charging module and the echo receiving module during the charging process. Alternatively, a physical shielding structure is provided between the internal charging module and the echo receiving module, such as an electromagnetic shielding cover, to reduce or avoid electromagnetic interference between the charging module and the echo receiving module during the charging process through physical isolation.

[0061] The second solution is to eliminate interference by staggering the timing of the ultrasound machine's charging and ultrasound imaging scans. That is, ultrasound imaging scans are not performed while the machine is charging, and the machine is not charged while it is imaging scans, so that there is no electromagnetic interference generated by charging during ultrasound imaging scans.

[0062] The third solution is to eliminate interference through data processing. After receiving the echo signal affected by electromagnetic interference, the ultrasound host performs filtering and other processing on the echo signal to remove the interference signal and ensure the imaging quality of the ultrasound image.

[0063] The above solutions can be selected individually or in combination into a portable ultrasound imaging device.

[0064] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0065] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0066] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0067] In one embodiment, a portable ultrasound imaging device is provided. This portable ultrasound imaging device can be a handheld terminal. The portable ultrasound imaging device may not include components such as a display module and control panel. The portable ultrasound imaging device only includes basic functions such as ultrasound scanning, energy storage and charging, and signal communication, which makes the portable ultrasound imaging device smaller and greatly improves portability. For example, users can carry the portable ultrasound imaging device with them.

[0068] When performing ultrasound imaging tests, this portable ultrasound imaging device needs to work in conjunction with a terminal device with display capabilities to achieve complete ultrasound imaging functions. The terminal device can be a mobile phone, tablet computer, traditional desktop ultrasound equipment, or traditional portable ultrasound equipment. The terminal device can also have stronger image processing capabilities than the portable ultrasound imaging device to achieve higher-resolution ultrasound imaging.

[0069] This portable ultrasound imaging device has a bidirectional charging function, which enables mutual charging between the portable ultrasound imaging device and the terminal device to balance the remaining battery life of the portable ultrasound imaging device and the terminal device, and ultimately improve the duration of collaborative operation between the portable ultrasound imaging device and the terminal device.

[0070] Please refer to Figure 1 The portable ultrasound imaging device of this embodiment mainly includes an ultrasound host 1. The ultrasound host 1 can be used to connect an ultrasound probe 2 and a terminal device 3 via wired or wireless means. The ultrasound host 1 connects to the ultrasound probe 2 and receives the ultrasound echo signal sent by the ultrasound probe. The ultrasound host 1 generates first ultrasound image data based on the ultrasound echo signal. The ultrasound host 1 connects to the terminal device 3 and can send the first ultrasound image data to the terminal device 3. The terminal device 3 processes the first ultrasound image data into an ultrasound image and displays it. Of course, the first ultrasound image data generated by the ultrasound host 1 based on the ultrasound echo signal can also be directly used for imaging display. For example, the ultrasound host 1 can process ultrasound images with relatively low resolution and directly display them to the terminal device 3, which can meet the needs of ordinary scenarios such as home use.

[0071] The ultrasound host 1 can be a handheld terminal product, convenient for users to hold and use. The weight of the ultrasound host 1 shall not exceed 500g, and the external dimensions of the ultrasound host 1 shall meet at least one of the following conditions: length not exceeding 200mm, width not exceeding 100mm, and height not exceeding 50mm. The length and width of the ultrasound host 1 can be the same as or similar to the length and width of an existing mobile phone, so as to facilitate holding and stacking the ultrasound host 1 and the mobile phone, and at the same time facilitate wireless charging and discharging between the ultrasound host 1 and the mobile phone.

[0072] Please refer to Figure 1 The ultrasound host 1 mainly includes a first ultrasound imaging module 11, a first energy storage module 12, and a first energy storage management module 13. The first ultrasound imaging module 11 includes at least a control unit, an image processing unit, and a communication unit, so that the first ultrasound imaging module 11 has control, processing, and communication functions. The control unit of the first ultrasound imaging module 11 is used to control the ultrasound probe 1 to emit ultrasound waves and receive ultrasound echoes. The control unit of the first ultrasound imaging module 11 is also used to control the reception of ultrasound echo information. The image processing unit of the first ultrasound imaging module 11 generates first ultrasound image data based on the processing of ultrasound echo signals. The communication unit of the first ultrasound imaging module 11 includes one or both of wired and wireless communication. The communication unit of the first ultrasound imaging module 11 is used to transmit the generated first ultrasound image data to the terminal device 3 via wired or wireless means.

[0073] The first energy storage module 12 may include an energy storage battery. The first energy storage module 12 is used to store electrical energy and can be charged and discharged. The first energy storage module 12 is used to provide electrical energy to the ultrasound host 1.

[0074] The first energy storage management module 13 may include a charge and discharge control unit. The first energy storage management module 13 is connected to the first energy storage module 12. The charge and discharge control unit of the first energy storage management module 13 is used to control the charging and discharging of the first energy storage module 12. The first energy storage management module 13 may also be connected to the first ultrasound imaging module 11. The first energy storage management module 13 controls the first energy storage module 12 to provide power to the ultrasound probe 2.

[0075] The first ultrasonic imaging module 11, the first energy storage module 12, and the first energy storage management module 13 can be configured as relatively independent components and connected via data cables or power cables. Alternatively, the first ultrasonic imaging module 11, the first energy storage module 12, and the first energy storage management module 13 can be integrated into a single structure and connected via traces on a circuit board.

[0076] In one embodiment, the first energy storage management module 13 may further include a charging and discharging module, which may include one or both of a wireless charging coil and a wired charging and discharging interface. The charging and discharging module of the first energy storage management module 13 connects the first energy storage module 12 to a power source, thereby enabling the charging and discharging of the first energy storage module 12.

[0077] In one embodiment, the charging and discharging control units in the first ultrasonic imaging module 11 and the first energy storage management module 13 can be combined into a single control management module.

[0078] In this embodiment, the first energy storage management module 13 controls the charging and discharging of the first energy storage module 12, including: when the ultrasound host 1 is connected to the terminal device 3, the first energy storage management module 13 controls the first energy storage module 12 to release electrical energy to the terminal device 3; or, the first energy storage management module 13 controls the terminal device 3 to release electrical energy to the first energy storage module 12, so as to balance the remaining battery life between the ultrasound host 1 and the terminal device 3, so that the remaining battery life of the ultrasound host 1 and the remaining battery life of the terminal device 3 are equal or approximately equal.

[0079] The ultrasound host 1 has a bidirectional charging function, meaning it can charge the terminal device 3, and the terminal device can also charge the ultrasound host 1. The ultrasound host 1 can also have a unidirectional charging function, for example, it can charge the terminal device 3, or the terminal device can charge the ultrasound host 1. This unidirectional charging function can also meet the needs of some usage scenarios. For example, when the maximum capacity of the first energy storage module 12 of the ultrasound host 1 is greater than the maximum capacity of the terminal device 3 (a small terminal such as a mobile phone), the terminal device 3's battery will generally run out first when the ultrasound host 1 and the terminal device 3 work together. Therefore, unidirectional charging from the ultrasound host 1 to the terminal device 3 can balance the remaining battery life between the ultrasound host 1 and the terminal device 3. Conversely, when the maximum capacity of the first energy storage module 12 of the ultrasound host 1 is less than the maximum capacity of the terminal device 3 (a large terminal such as a tablet), the ultrasound host 1's battery will generally run out first when the ultrasound host 1 and the terminal device 3 work together. Therefore, unidirectional charging from the terminal device 3 to the ultrasound host 1 can balance the remaining battery life between the ultrasound host 1 and the terminal device 3.

[0080] The first energy storage management module 13 is used to calculate and compare the remaining battery life of the ultrasound host 1 and the remaining battery life of the terminal device 3. Based on the comparison result, the first energy storage management module 13 controls the first energy storage module 12 to release electrical energy to the terminal device 3; or, controls the terminal device 3 to release electrical energy to the first energy storage module 12. For example, when the ultrasound host 1 stores more electrical energy and its remaining battery life is greater than that of the terminal device 3, the first energy storage management module 13 controls the first energy storage module 12 to release electrical energy to the terminal device 3; when the terminal device 3 stores more electrical energy and its remaining battery life is greater than that of the ultrasound host 1, the first energy storage management module 13 controls the terminal device 3 to release electrical energy to the first energy storage module 12.

[0081] The first energy storage management module 13 can calculate the remaining driving time using the following formula:

[0082] T = E / V

[0083] Where T represents the remaining battery life, E represents the current battery level, and V represents the current rate of battery consumption.

[0084] The first energy storage management module 13 mainly detects the discharge current of the first energy storage module 12 and the discharge current of the terminal device 3. By detecting the discharge current, the consumed electrical energy can be calculated, that is, the current power E can be calculated. The current power consumption rate V is calculated by the difference between the power of the previous moment and the current power. Current consumption rate = (power of the previous moment - current power) / time difference between the two moments. Finally, the remaining battery life T is calculated by the formula T = E / V.

[0085] In one embodiment, if the terminal device 3 has its own power monitoring and display, such as mobile phones and tablets having their own monitoring and display of remaining power and remaining battery life, then the first energy storage management module 13 can directly obtain the remaining battery life information of the terminal device 3, and the first energy storage management module 13 does not need to monitor the power of the terminal device 3.

[0086] In one embodiment, the terminal device 3 may be equipped with a second energy storage management module. This second energy storage management module can execute the control of the first energy storage management module 13. Specifically, when the ultrasound host 1 is connected to the terminal device 3, the second energy storage management module controls the first energy storage module 12 to release electrical energy to the terminal device 3; or, the second energy storage management module controls the terminal device 3 to release electrical energy to the first energy storage module 12, thereby balancing the remaining battery life between the ultrasound host 1 and the terminal device 3. In other words, the ultrasound host 1 may not have a first energy storage management module 13; instead, the second energy storage management module of the terminal device 3 can control the charging and discharging process. Of course, the ultrasound host 1 can also retain the first energy storage management module 13. The first energy storage management module 13 and the second energy storage management module work together to control and balance the remaining battery life between the ultrasound host 1 and the terminal device 3. For example, the first energy storage management module 13 is used to control the first energy storage module 12 to release electrical energy to the terminal device 3, and the second energy storage module is used to control the terminal device 3 to release electrical energy to the first energy storage module 12; or, one of the first energy storage module 13 and the second energy storage module performs charging and discharging control, and the other serves as a backup.

[0087] In one embodiment, the first energy storage management module 13 is provided with a remaining battery life threshold. The remaining battery life threshold is used as a trigger value to determine the charge-discharge balance. If the threshold is not reached, it means that both the ultrasound host 1 and the terminal device 3 have enough power to perform ultrasound imaging detection. If the threshold is reached, it means that one of the ultrasound host 1 and the terminal device 3 has too low power, triggering mutual charging between the ultrasound host 1 and the terminal device 3 to achieve a balance of remaining battery life and improve the duration of collaborative operation between the ultrasound host 1 and the terminal device 3.

[0088] The principle of triggering mutual charging between the ultrasound host 1 and the terminal device 3 based on the remaining battery life threshold is as follows:

[0089] If the remaining battery life of the ultrasound host 1 is less than the remaining battery life threshold of the ultrasound host 1, then the first energy storage management module 13 controls the terminal device 3 to release electrical energy to the ultrasound host 1; if the remaining battery life of the terminal device 3 is less than the remaining battery life threshold of the terminal device 3, then the ultrasound host 1 controls the ultrasound host 1 to release electrical energy to the terminal device 3.

[0090] For example, if the remaining battery life threshold is set to 10 minutes, and the remaining battery life of the ultrasound host 1 is less than 10 minutes while the remaining battery life of the terminal device 3 is greater than 10 minutes, then the terminal device 3 is controlled to release power to the ultrasound host 1; if the remaining battery life of the terminal device 3 is less than 10 minutes while the remaining battery life of the ultrasound host 1 is greater than 10 minutes, then the ultrasound host 1 is controlled to release power to the terminal device 3.

[0091] In one embodiment, the remaining battery life threshold can also be set within the terminal device 3. The second energy storage management module within the terminal device 3 controls the terminal device 3 to release electrical energy to the ultrasound host 1, and controls the ultrasound host 1 to release electrical energy to the terminal device 3.

[0092] In one embodiment, the first energy storage management module 13 includes a wireless charging and discharging management module, which may include a wireless charging coil. The ultrasound host 1 with the wireless charging and discharging management module can wirelessly charge and discharge with the terminal device 3, which has a corresponding wireless charging and discharging management module. Using wireless charging and discharging allows the ultrasound host 1 and the terminal device 3 to be stacked vertically, reducing the use of cables and facilitating user operation.

[0093] Please refer to Figure 2 In one embodiment, the ultrasound host 1 further includes a wired power interface 14, which can be connected to the terminal device 3 via a cable 4. The ultrasound host 1 and the terminal device 3 can achieve wired charging and discharging via the cable 4. The wired power interface 14 can also serve as a communication interface, so that the cable 4 can also transmit information such as first ultrasound image data.

[0094] Two wired power interfaces 14 can be provided. One wired power interface 14 is used to connect to the terminal device 3 via cable 4, and the other wired power interface 14 can be connected to a mobile power supply or a fixed power supply via cable. This allows the ultrasound host 1 to be charged and the terminal device 3 to be charged indirectly when the ultrasound host 1 and the terminal device 3 are connected and working together, thereby increasing the remaining battery life.

[0095] The ultrasound host 1 may include one of a wireless charging and discharging management module and a wired power interface 14 to realize wired or wireless charging and discharging. The ultrasound host 1 may also include a wireless charging and discharging management module and a wired power interface 14 to realize wired and wireless charging and discharging, giving users more charging options.

[0096] Please refer to Figure 3In one embodiment, the ultrasound host 1 may further include a transmitting and receiving module 15. The ultrasound host 1 is connected to the ultrasound probe 2 through the transmitting and receiving module 15. The transmitting and receiving module 15 is used to control the transmitting and receiving operation of the ultrasound probe 2. The first ultrasound imaging module 11 can receive ultrasound echo signals through the transmitting and receiving module 15.

[0097] The first energy storage management module 13 and the transmitting and receiving module 15 inside the ultrasonic host 1 are electromagnetically shielded from each other so that the first energy storage management module 13 will not cause electromagnetic interference to the transmitting and receiving module 15 in receiving ultrasonic echo signals during the charging and discharging process.

[0098] The ultrasound host 1 can be a rectangular structure, with a first end and a second end opposite each other along its length. The first end of the ultrasound host 1 is used for connection with the terminal device 3, and the second end of the ultrasound host 1 is used for connection with the ultrasound probe 2. The first energy storage management module 13 is located at the first end of the ultrasound host 1, and the transmitting and receiving module 15 is located at the second end of the ultrasound host 1. The first energy storage management module 13 and the transmitting and receiving module 15 are located at opposite ends of the ultrasound host 1, and their relatively far apart arrangement ensures that charging and discharging occur at the first end of the ultrasound host 1, while the reception of the ultrasound echo signal occurs at the second end of the ultrasound host 1, thus minimizing electromagnetic interference from charging and discharging on the received ultrasound echo signal.

[0099] In one embodiment, an electromagnetic shielding structure may be provided inside the ultrasound host 1. This electromagnetic shielding structure is located between the first energy storage management module 13 and the transmitting / receiving module 15, physically separating them. For example, the first energy storage management module 13 is located at the first end of the ultrasound host 1, the transmitting / receiving module 15 is located at the second end, and the electromagnetic shielding structure is located in the middle of the ultrasound host 1. The electromagnetic shielding structure includes an electromagnetic shielding cover or an electromagnetic shielding film, which can be made of metal. The electromagnetic shielding cover or electromagnetic shielding film can shield against electromagnetic interference, eliminating electromagnetic interference to the received ultrasonic echo signal during charging and discharging.

[0100] In one embodiment, the ultrasonic host 1 is configured to have the transmitting and receiving module 15 transmitting and receiving and the first energy storage management module 13 charging and discharging at different times. Specifically, the transmitting and receiving module 15 and the first energy storage management module 13 cannot operate simultaneously. When the transmitting and receiving module 15 is in transmitting and receiving mode, it cannot charge or discharge even when an external power source is connected. Similarly, when the ultrasonic host 1 and the terminal device 3 are in a mutual charging and discharging state, or when the ultrasonic host 1 is connected to an external power source and is charging, the transmitting and receiving module 15 cannot transmit or receive. This staggered timing ensures that when the transmitting and receiving module 15 is in transmitting and receiving mode, there is no electromagnetic interference from charging and discharging, thus guaranteeing the quality of the received ultrasonic echo signal.

[0101] In one embodiment, when the first ultrasound imaging module 11 of the ultrasound host 1 generates first ultrasound image data based on ultrasound echo signals, it includes data processing operations such as filtering to eliminate interference signals generated by charging and discharging, so that the first ultrasound image data does not include interference data, and the quality of the ultrasound image can still be guaranteed.

[0102] Please refer to Figure 4 In one embodiment, the ultrasound host 1 may further include a probe interface 16 for detachably connecting different types of ultrasound probes 2. Each ultrasound probe 2 includes a probe 21 and a plug 22. The probe 21 is a transducer used to emit ultrasonic waves and receive ultrasonic echoes. The probe 21 and the plug 22 are connected by a cable. The plug 22 is adapted to the probe interface 16 and can be inserted into the probe interface 16 to achieve connection. Different types of ultrasound probes 2 have different probe 21 models and the same type of plug 22, allowing the probe interface 16 fixed on the ultrasound host 1 to be compatible with different types of ultrasound probes 2.

[0103] The probe interface 16 can be located on the second end face of the ultrasound host 1, and the probe interface 16 almost covers the second end face of the ultrasound host 1, so as to minimize the external volume of the ultrasound host 1 and achieve miniaturization.

[0104] Please refer to Figure 4 In one embodiment, the portable ultrasound imaging device includes an ultrasound host 1 and an ultrasound probe 2 as described in any of the above embodiments. The ultrasound probe 2 is used to emit ultrasound waves toward the imaging target and receive ultrasound echo signals returned by the imaging target.

[0105] The plug 22 of the ultrasound probe 2 is adapted to connect with the probe interface 16. The ultrasound probe 2 can include various different models, such as a linear array probe or a planar array probe. Different models of ultrasound probe 2 are used for different parts of the body. Different models of ultrasound probe 2 can be detachably connected to the ultrasound host 1. Users can select the required ultrasound probe 2 to connect to the ultrasound host 1 as needed.

[0106] The ultrasound host 1 and the ultrasound probe 2 can also be configured as an integrated, non-detachable structure. For example, the probe 21 of the ultrasound probe 2 can be directly connected to the transmitting and receiving module 15 inside the ultrasound host 1 via a cable; or, the probe 21 of the ultrasound probe 2 can be directly fixed to the outer shell of the ultrasound host 1.

The second energy storage module 31 is connected to the display module 33, and the second energy storage module 31 provides power to the display module 33. The display module 33 is used to display the first ultrasound image data sent by the ultrasound host 1.

[0108] When the ultrasound host 1 is connected to the terminal device 3 and works together, the first energy storage management module 13 controls the first energy storage module 12 to discharge to the second energy storage module 31, and the first energy storage management module 13 controls the second energy storage module 31 to discharge to the first energy storage module 12, so as to balance the remaining battery life between the ultrasound host 1 and the terminal device 3 and increase the total working time of the ultrasound host 1 and the terminal device 3.

[0109] Please refer to Figure 6 In one embodiment, the portable ultrasound imaging device includes the ultrasound host 1 and terminal device 3 as described in any of the above embodiments. The terminal device 3 is used to control the charging and discharging between the ultrasound host 1 and the terminal device 3.

The display module 33 may also not be connected to the second energy storage module 31.

[0111] The display module 33 can be a display component such as a monitor or a touch screen. The second energy storage module 31 is connected to the display module 33 and provides power to the display module 33. The display module 33 is used to display the first ultrasound image data sent by the ultrasound host 1.

[0112] When the terminal device 3 is connected to the ultrasound host 1 and works together, the second energy storage management module 32 is used to control the second energy storage module 31 to release electrical energy to the first energy storage module 12, or the second energy storage management module 32 is used to control the first energy storage module 12 to release electrical energy to the second energy storage module 31, so as to balance the remaining battery life between the ultrasound host 1 and the terminal device 3.

[0113] Please refer to Figure 7 In one embodiment, the portable ultrasound imaging device includes an ultrasound host 1, an ultrasound probe 2, and a terminal device 3 as described in any of the above embodiments. The ultrasound probe 2 is used to emit ultrasound waves towards the imaging target and receive ultrasound echo signals returned by the imaging target. The ultrasound probe 2 is also used to transmit the ultrasound echo signals to the ultrasound host 1. The ultrasound host 1 generates first ultrasound image data based on the ultrasound echo signals and sends it to the terminal device 3. The terminal device 3 is used to display the first ultrasound image data. The ultrasound host 1 and the terminal device 3 are detachably connected by a wired connection or a wireless connection; the ultrasound host 1 and the terminal device 3 can communicate via a wired or wireless channel, and can be wired or wirelessly charged and discharged.

[0114] In one embodiment, the portable ultrasound imaging device includes an ultrasound host 1. The ultrasound host 1 may not have bidirectional charging; instead, it has unidirectional charging functionality. The ultrasound host 1 can be connected to an external power source for charging, or it can be connected to a terminal device 3, which charges the ultrasound host 1. The ultrasound host 1 includes any of the above-mentioned methods to eliminate electromagnetic interference from charging on the echo signal, particularly eliminating electromagnetic interference from wireless charging on the received ultrasound echo signal.
