Currently, doctors often need to use multiple probes to complete the examination work due to different organs, different parts and different examination requirements when using ultrasonic machines. However, the current portable ultrasonic imaging device generally has only one probe interface. If the doctor needs to use multiple probes for examination, the doctor generally needs to replace the probe through manual plugging and unplugging, which is troublesome and not conducive to the doctor's use. If the doctor does not replace the probe through manual plugging and unplugging, the doctor generally needs to purchase an additional probe extender, which will increase the cost burden. In addition, some portable ultrasonic imaging devices support two or three probe interfaces, but generally achieve this through independent probe board cards. Each probe interface needs a probe board card, that is, multiple circuit boards are needed to achieve multiple probe interfaces, which is not conducive to the doctor's mobile carrying in terms of form, volume and weight.

[0020] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein. Based on the embodiments of this application described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this application.

[0021] Figure 1 A schematic structural block diagram of a portable ultrasound imaging device 1 according to an embodiment of this application is shown. Figure 1 As shown, the portable ultrasound imaging device 1 may include an ultrasound host 11, a control panel 12, and a display screen 13. The control panel 12 is connected to the ultrasound host 11 and is used to input ultrasound commands. The display screen 13 is connected to the ultrasound host 11 and is used to display ultrasound images. The ultrasound host 11 includes a housing 111, a circuit board 112 located within the housing 111, and a power supply 113. The circuit board 112 is provided with a probe interface circuit 1121, a probe switching circuit 1122, a transmitting circuit 1123, a receiving circuit 1124, a data processing and uploading circuit 1125, and a processor interface circuit 1126. The power supply 113 is used to power the circuit board. The housing 111 has at least two probe interface positions 114, through which an ultrasound probe (not shown) is connected to the probe interface circuit 1121. For simplicity, ... Figure 1 The diagram shows two probe interfaces 114. In practice, there may be three or more probe interface positions 114. Correspondingly, the probe interface circuit 1121 may include three or more probe interface terminals. On the circuit board 112: the probe interface circuit 1121 is located between the probe switching circuit 1122 and the transmitting circuit 1123; the receiving circuit 1124 is located between the transmitting circuit 1123 and the data processing and uploading circuit 1125; the data processing and uploading circuit 1125 is located between the receiving circuit 1124 and the processor interface circuit 1126.

[0022] The probe interface circuit 1121 is mainly used to realize the connection function of the ultrasonic host 11 and an external ultrasonic probe. The probe switching circuit 1122 is mainly used to realize the switching function between multiple probe interfaces. Exemplarily, the probe switching circuit 1122 can include a relay or a high-voltage analog switch chip. The transmitting circuit 1123 realizes the signal transmitting function, which is used to control the ultrasonic wave transmitting of the ultrasonic probe, and generally adopts a pulse type transmitting scheme. The receiving circuit 1124 realizes the signal receiving function. The ultrasonic probe converts the received ultrasonic echo into an electric signal, which is received by the interface circuit. The interface circuit converts the analog electric signal into a digital electric signal and sends it to the data processing uploading circuit 1125. The data processing uploading circuit 1125 is used to perform post-processing on the received data and provide it to a processing unit (such as a central processing unit) through the processor interface circuit 1126. The processor interface circuit 1126 includes a carrier connector, which is used to support the communication, control, power supply and the like between the processing unit and the circuit board 112. Exemplarily, the processor interface circuit 1126 can include a serial communication interface circuit, such as a COME (COM Express) interface, or other connectors.

[0023] In the embodiment of the present application, the circuit board 112 is included in the shell 111 of the ultrasonic host 11. The probe interface circuit 1121, the probe switching circuit 1122, the transmitting circuit 1123, the receiving circuit 1124, the data processing uploading circuit 1125 and the processor interface circuit 1126 are all arranged on the circuit board 112, that is, the layout scheme of realizing multiple probe interfaces by a single main board can be realized in the present application. For this layout scheme, the relative position relationship of the probe interface circuit 1121, the probe switching circuit 1122, the transmitting circuit 1123, the receiving circuit 1124, the data processing uploading circuit 1125 and the processor interface circuit 1126 is mainly considered. Through the relationship between the circuit functions and the physical minimum spacing layout, it is ensured that the functions of imaging, control and multiple probe interfaces can be realized on a single main board.

[0024] Specifically, on the circuit board 112: the probe interface circuit 1121 is arranged between the probe switching circuit 1122 and the transmitting circuit 1123; the receiving circuit 1124 is arranged between the transmitting circuit 1123 and the data processing uploading circuit 1125; and the data processing uploading circuit 1125 is arranged between the receiving circuit 1124 and the processor interface circuit 1126. From the layout scheme, it can be known that the probe switching circuit 1122 is closer to the edge of the circuit board 112 relative to the probe interface circuit 1121, that is, the probe switching circuit 1122 is on the outside and the probe interface circuit 1121 is on the inside. This layout has the advantage of being conducive to product miniaturization.

[0025] This is because, due to the need of the probe interface circuit 1121 to provide interface terminals, reserved interface space, so that the ultrasonic probe is inserted from the interface, therefore, the area of the bottom of the probe interface circuit 1121 (i.e. the first surface located on the circuit board 112) is small, but the area of the surface formed after extending vertically from the bottom to the circuit board 112 (i.e. the second surface parallel to the first surface) is large. The probe switching circuit 1122 is arranged on the inner side, and the probe interface circuit 1121 is arranged on the outer side, due to the above-mentioned area relationship, the probe interface circuit 1121 occupies a large space, because it is necessary to reserve space according to the area of the second surface. The layout scheme of the present application arranges the probe switching circuit 1122 on the outer side, and the probe interface circuit 1121 on the inner side, so that the probe interface circuit 1121 occupies a small space, because it is necessary to reserve space according to the area of the first surface, and the second surface is located higher than the surface of the probe switching circuit 1122, so the second surface can cover part of the space of the probe switching circuit 1122, in this way, the layout scheme of saving space is realized, which is beneficial to the miniaturization of the product, and the miniaturization of the product provides the possibility for the single main board to realize multiple probe interfaces.

[0026] In addition, the transmitting circuit 1123 is close to the probe interface circuit 1121, which is more convenient for the transmitting circuit 1123 to control the transmission of the ultrasonic probe connected to the probe interface circuit 1121. The receiving circuit 1124 is closer to the data processing and uploading circuit 1125, which is more convenient for it to transmit the received signals to the data processing and uploading circuit 1125 after processing. The data processing and uploading circuit 1125 is close to the processor interface circuit 1126, which is more convenient for it to transmit the processed signals to the processor interface circuit 1126 for transmission to the processing unit for processing.

[0027] Overall, the portable ultrasonic equipment according to the embodiments of the present application can realize single main board to realize multiple probe interfaces, without manual plugging and unplugging to replace the probe, and compared with the scheme of additionally purchasing a probe expander, and compared with the scheme of realizing multiple probe interfaces through multiple independent probe board cards, both can not only reduce the cost, but also realize the miniaturization of the product, which is beneficial to the doctor to move and carry from the form, volume and weight.

[0028] The layout scheme of the circuit on the circuit board 112 in the shell 111 of the ultrasonic host 11 of the portable ultrasonic equipment of the present application will be described below in combination with different examples.

[0029] In one example, as shown in FIG. 7, the probe switching circuit 1122 is arranged on the outer side of the circuit board 112, and the probe interface circuit 1121 is arranged on the inner side of the circuit board 112. Figure 2As shown, circuit board 112 has a first side and a second side opposite to the first side. Portable ultrasound imaging device 1 is connected to an ultrasound probe from the first side. Probe switching circuit 1122 is located closest to the first side. The circuits on circuit board 112, from the first side to the second side, are as follows: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126.

[0030] In this example, taking the orientation when facing the circuit board 112 as a reference, the first side is the right side of the object facing the circuit board 112, and the second side is the left side. That is, the probe is inserted into the ultrasound host 11 from the right side. This probe insertion orientation is common and suitable for the operating habits of right-handed users. In this example, the circuits on the circuit board 112, from the right side to the left side, are: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126. As mentioned above, this allows for multiple probe interfaces on a single motherboard, with the probe switching circuit 1122 on the outer side (far right) and the probe interface circuit 1121 on the inner side, which is beneficial for product miniaturization. Furthermore, providing a probe insertion method from the right side satisfies the usage habits of most users (since most people are right-handed), resulting in a good user experience.

[0031] In another example, such as Figure 3 As shown, circuit board 112 has a first side and a second side opposite to the first side. Portable ultrasound imaging device 1 is connected to an ultrasound probe from the second side. Probe switching circuit 1122 is located closest to the second side. The circuits on circuit board 112, from the second side to the first side, are as follows: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126.

[0032] In this example, taking the orientation when facing the circuit board 112 as a reference, the first side is the right side of the object facing the circuit board 112, and the second side is the left side of the object facing the circuit board 112. That is, the probe is inserted into the ultrasound host 11 from the left, which is more suitable for the operating habits of left-handed users. In addition, human-computer interaction devices, such as mice, are generally on the right side of the object, so inserting the probe on the left side can also avoid affecting the operation of the human-computer interaction device. In this example, the circuits on the circuit board 112, from the left side to the right side, are: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126. As mentioned above, a single motherboard can realize multiple probe interfaces, and the probe switching circuit 1122 is on the outside (leftmost side), while the probe interface circuit 1121 is on the inside, which is beneficial for product miniaturization. In addition, the option to insert the probe from the left side caters to the usage habits of left-handed users and avoids affecting the operation of human-computer interaction devices, resulting in a good user experience.

[0033] In another example, such as Figure 4 As shown, circuit board 112 has a third side and a fourth side opposite to the third side. Portable ultrasound imaging device 1 is connected to an ultrasound probe from the third side. Probe switching circuit 1122 is located closest to the third side. The circuits on circuit board 112, from the third side to the fourth side, are as follows: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126.

[0034] In this example, taking the direction when facing the circuit board 112 as a reference, the third side is the upper side (also called the far side, or the top or upper side of the circuit board 112 from the angle of the circuit board 112), and the fourth side is the lower side (also called the near side, or the bottom or lower side of the circuit board 112 from the angle of the circuit board 112). That is, the probe is inserted into the ultrasound host 11 from the top, and this probe insertion direction also avoids affecting the operation of the human-computer interaction device. In this example, the circuits on the circuit board 112, from the above-mentioned top side to the above-mentioned bottom side, are: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126. As mentioned above, a single motherboard can realize multiple probe interfaces, and the probe switching circuit 1122 is on the outside (topmost side), while the probe interface circuit 1121 is on the inside, which is beneficial for product miniaturization. Furthermore, the top-insertion method of the probe caters to both left- and right-handed users and avoids interfering with the operation of human-computer interaction devices, resulting in a good user experience and flexible use.

[0035] In yet another example, such as Figure 5 As shown, circuit board 112 has a third side and a fourth side opposite to the third side. Portable ultrasound imaging device 1 is connected to an ultrasound probe from the fourth side. Probe switching circuit 1122 is located closest to the fourth side. The circuits on circuit board 112, from the fourth side to the third side, are as follows: probe switching circuit 1122, probe interface circuit 1121, transmitting circuit 1123, receiving circuit 1124, data processing and uploading circuit 1125, and processor interface circuit 1126.

[0036] In this example, with the direction of facing the circuit board 112 as a reference, the third side is the upper side of the object facing the circuit board 112 (also referred to as the distal side, or from the perspective of the circuit board 112, it can also be referred to as the top side or the upper side of the circuit board 112), and the fourth side is the lower side of the object facing the circuit board 112 (also referred to as the proximal side, or from the perspective of the circuit board 112, it can also be referred to as the bottom side or the lower side of the circuit board 112). That is, the probe is inserted into the ultrasound host 11 from the lower side, and the access direction of such a probe can also avoid affecting the operation of the human-computer interaction device. In this example, the circuits on the circuit board 112 from the above-mentioned lower side to the above-mentioned upper side are respectively: the probe switching circuit 1122, the probe interface circuit 1121, the transmitting circuit 1123, the receiving circuit 1124, the data processing upload circuit 1125, and the processor interface circuit 1126. As described above, a single main board can realize multiple probe interfaces, and the probe switching circuit 1122 is on the outer side (the lowermost side), and the probe interface circuit 1121 is on the inner side, which is conducive to product miniaturization. In addition, since the probe is inserted from the lower side, the use habits of left-handed and right-handed users can be met at the same time, and the operation of the human-computer interaction device is not affected, the user experience is good, and the use is flexible.

[0037] In the above example, the power supply 113 is not shown, and the power supply 113 can be arranged on the left side or the lower side of the probe interface circuit 1121, or any other suitable position.

[0038] In further embodiments of the present application, the transmitting circuit 1123, the receiving circuit 1124, the data processing upload circuit 1125, and the processor interface circuit 1126 are arranged approximately in parallel on the circuit board 112 (as shown in Figures 1 to 5 The approximate parallel arrangement of these circuits on the circuit board 112 makes the transmission and flow of signals more smooth.

[0039] In the embodiments of this application, the data processing and uploading circuit 1125 can be implemented by a programmable device. The programmable device is electrically connected to the probe interface circuit 1121, the probe switching circuit 1122, the transmitting circuit 1123, the receiving circuit 1124, and the processor interface circuit 1126. In this embodiment, the probe interface circuit 1121, the probe switching circuit 1122, the transmitting circuit 1123, the receiving circuit 1124, and the processor interface circuit 1126 are all electrically connected to the programmable device that implements the data processing and uploading circuit 1125, so that the programmable device can control the probe interface circuit 1121, the probe switching circuit 1122, the transmitting circuit 1123, the receiving circuit 1124, and the processor interface circuit 1126, thereby realizing the control of the entire ultrasound imaging process by a single programmable logic device. Specifically, the programmable device can implement corresponding data receiving functions, data sending functions, command transmission functions, and / or status monitoring functions for the probe interface circuit 1121, probe switching circuit 1122, transmitting circuit 1123, receiving circuit 1124, and / or processor interface circuit 1126.

[0040] For example, the programmable device can be any of the following: Field Programmable Gate Array (FPGA), Complex Programmable Logic Device (CPLD), Microcontroller Unit (MCU), or Reduced Instruction Set Machine (ARM).

[0041] In a further embodiment of this application, electromagnetic shielding covers (not shown) may be provided on the processor interface circuit 1126, the transmitting circuit 1123, the interface circuit, and the data processing and uploading circuit 1125. A centralized heat dissipation circuit is also provided on the circuit board 112. The centralized heat dissipation circuit includes a first heat-conducting component and a second heat-conducting component, wherein: the first heat-conducting component is disposed on the electromagnetic shielding cover of the processor interface circuit 1126; and the second heat-conducting component is disposed on the electromagnetic shielding covers of the transmitting circuit 1123, the interface circuit, and the data processing and uploading circuit 1125. Because the data uploading and processing circuit and the processor interface circuit 1126 are relatively close in the layout scheme of this application, centralized heat dissipation is more convenient.

[0042] In a further embodiment of this application, a probe channel expansion circuit (not included) is also provided on the circuit board 112. Figures 1 to 5 As shown in the figure (and will be illustrated in the embodiments below), the probe channel expansion circuit is disposed between the probe interface circuit 1121 and the transmitting circuit 1123. The probe channel expansion circuit enables probe channel expansion to meet different scenario requirements. For example, the probe channel expansion circuit can expand 64 channels to 128 channels, or 32 channels to 64 channels, or 64 channels to 80 channels, 96 channels, or 128 channels, etc.

[0043] The following is combinedFigures 6 to 10 A portable ultrasound imaging device 2 according to another embodiment of this application is described. It is generally similar to the portable ultrasound imaging device 1 described above, except that the portable ultrasound imaging device 2 has a probe expansion circuit added to its circuit board, enabling it to not only perform the functions of the portable ultrasound imaging device 1 but also meet the needs of more scenarios. Those skilled in the art can understand the structure and circuit board layout of the portable ultrasound imaging device 2 in conjunction with the foregoing description. For the sake of brevity, details are not repeated here, only some key aspects are described.

[0044] Figure 6 A schematic structural block diagram of a portable ultrasound imaging device 2 according to one embodiment of this application is shown. Figure 6 As shown, the portable ultrasound imaging device 2 may include an ultrasound host 11, a control panel 12, and a display screen 13. The control panel 12 is connected to the ultrasound host 11 and is used to input ultrasound commands. The display screen 13 is connected to the ultrasound host 11 and is used to display ultrasound images. The ultrasound host 11 includes a housing 111, a circuit board 112 located within the housing 111, and a power supply 113. The circuit board 112 is equipped with a probe interface circuit 1121, a probe switching circuit 1122, a transmitting circuit 1123, a receiving circuit 1124, a data processing and uploading circuit 1125, a processor interface circuit 1126, and a probe channel expansion circuit 1127. The power supply 113 supplies power to the circuit board. The housing 111 has at least two probe interface positions 114, through which an ultrasound probe (not shown) is connected to the probe interface circuit 1121. For simplicity, ... Figure 6 The diagram shows two probe interfaces 114. In practice, there may be three or more probe interface positions 114. Correspondingly, the probe interface circuit 1121 may include three or more probe interface terminals. On the circuit board 112: the probe interface circuit 1121 is located between the probe switching circuit 1122 and the transmitting circuit 1123; the receiving circuit 1124 is located between the transmitting circuit 1123 and the data processing and uploading circuit 1125; the data processing and uploading circuit 1125 is located between the receiving circuit 1124 and the processor interface circuit 1126; and the probe channel expansion circuit 1127 is located between the probe interface circuit 1121 and the transmitting circuit 1123.

[0045] In the embodiment of the present application, the circuit board 112 is included in the shell 111 of the ultrasonic host 11, the probe interface circuit 1121, the probe switching circuit 1122, the probe channel expansion circuit 1127, the transmitting circuit 1123, the receiving circuit 1124, the data processing uploading circuit 1125 and the processor interface circuit 1126 are arranged on the circuit board 112, that is, the layout scheme of the single main board realizing the multi-probe interface can be realized. For the layout scheme, the relative position relationship of the probe interface circuit 1121, the probe switching circuit 1122, the probe channel expansion circuit 1127, the transmitting circuit 1123, the receiving circuit 1124, the data processing uploading circuit 1125 and the processor interface circuit 1126 is mainly considered, through the relationship between the circuit functions, the physical minimum spacing layout is realized, and the functions of imaging, control and multi-probe interface on the single main board can be realized.

[0046] Specifically, on the circuit board 112: the probe interface circuit 1121 is arranged between the probe switching circuit 1122 and the transmitting circuit 1123; the receiving circuit 1124 is arranged between the transmitting circuit 1123 and the data processing uploading circuit 1125; the data processing uploading circuit 1125 is arranged between the receiving circuit 1124 and the processor interface circuit 1126; and the probe channel expansion circuit 1127 is arranged between the probe interface circuit 1121 and the transmitting circuit 1123. From the layout scheme, it can be known that the probe switching circuit 1122 is closer to the edge of the circuit board 112 relative to the probe interface circuit 1121, that is, the probe switching circuit 1122 is on the outside and the probe interface circuit 1121 is on the inside, and the layout has the advantage of being beneficial to product miniaturization.

[0047] In addition, the probe channel expansion circuit 1127 is close to the probe interface circuit 1121, which is more convenient for expanding the probe channel.
