[0040] The present application provides a portable ultrasound device, which separates the IO interface from the main board and integrates one or more IO interfaces into one or more IO interface modules. The IO interface module can be detachably installed on the host and then connected to the main board through a connection terminal. Therefore, if the IO interface is damaged, there is no need to disassemble the main board casing or replace the main board. Instead, the IO interface module only needs to be removed and replaced with a new IO interface module and installed on the main board. This makes disassembly and assembly easy, the replacement cost is low, and it is convenient for customers to customize and select different models of IO interfaces.

[0041] The present invention will be further described in detail below through specific embodiments with reference to the accompanying drawings.

[0042] In one embodiment, a portable ultrasound device is provided, such as Figure 1 and Figure 3 As shown, the portable ultrasound device mainly includes a main body 10 and a flip cover 40. The flip cover 40 is flippably mounted on the main body 10 via a rotating shaft. Figure 1The main unit 10 is mounted on the upper end of the main unit 10. A control panel is mounted on the top surface of the main unit 10. The control panel may include buttons, a trackball, and / or a touch area, which can be used to operate the portable ultrasound device for testing, view ultrasound images acquired by the portable ultrasound device, and so on. The main unit 10 includes a main board 20, to which the control panel is connected. A first display screen is mounted on the surface of the flip cover 40 facing the main unit 10. The first display screen is connected to the main board 20 and is used to display information such as the operating interface and test results. The overall structure of the portable ultrasound device can be similar to that of a laptop computer.

[0043] The host computer 10 may include a housing, with the motherboard 20 mounted within the housing. An opening 11 is provided on the left side of the host computer 10 (housing). Opening 11 is rectangular. Opening 11 may also be provided on the right side, front side, or rear side of the host computer 10 (housing). Opening 11 may also have an oval shape or other configuration. One or more IO interface modules 30 are removably mounted in opening 11 of the host computer 10.

[0044] like Figure 2 and Figure 3 As shown, the IO interface module 30 mainly includes a circuit board 31 and IO interface terminals 32. There are one or more IO interface terminals 32, which are installed side by side on one side of the circuit board 31. A first connection terminal 33 is installed on the other side of the circuit board 31. Correspondingly, a second connection terminal 21 is provided on the side of the mainboard 20 near the opening 11, that is, near the IO interface module 30. The first connection terminal 33 and the second connection terminal 21 are adapted to each other.

[0045] The IO interface module 30 is installed within the opening 11 of the host 10. The IO interface module 30 is snap-fitted to the host 10 via a circuit board 31. The circuit board 31 is entirely located within the host 10, and first connection terminals 33 on the circuit board 31 connect to second connection terminals 21 on the mainboard 20 to enable communication. IO interface terminals 32 are exposed through the opening of the host 10 for connection to external devices. The IO interface module 30 is installed on the host 10 as a removable transition module, facilitating replacement and maintenance of the IO interface.

[0046] In this embodiment, the circuit board 31 and the mainboard 20 are arranged side by side on the same mounting surface, and the sum of their lengths is less than the width of the interior space of the host 10. The circuit board 31 and the mainboard 20 can also be installed in a staggered manner, for example, with the circuit board 31 on top and the mainboard 20 on the bottom, with the second connection terminals 21 on the mainboard 20 extending upward so that the second connection terminals 21 are aligned and connected with the first connection terminals 33 on the circuit board 31.

[0047] In one embodiment, the first connection terminal 33 on the circuit board 31 and the second connection terminal on the main board 20 can be a pair of board-to-board connection terminals, and the pair of first connection terminals 33 and second connection terminals 21 of the board-to-board can realize a detachable plug-in connection. The first connection terminal 33 is connected to all the IO interface terminals 32 through the circuit board 31, so that all the IO interface terminals 32 realize communication with the main board 20 through the connection of the first connection terminal 33 and the second connection terminal 21. The board-to-board connector formed by a pair of board-to-board connection terminals has a small contact impedance and thus has a good signal transmission capability. When the first connection terminal and the second connection terminal are formed as a board-to-board connector, it can be better suitable for application scenarios where portable ultrasound equipment needs to use a probe to collect image signals, thereby reducing the attenuation of the probe signal as much as possible.

[0048] In one embodiment, both the first connection terminal 33 and the second connection terminal 21 have metal contact ends with contact surfaces, and the first connection terminal 33 and the second connection terminal 21 are connected to each other through surface-to-surface contact. This surface-to-surface contact reduces the installation and positioning requirements of the IO interface module 30, allowing for a certain degree of tolerance between the first connection terminal 33 and the second connection terminal 21, thereby reducing the difficulty of production and installation.

[0049] To make the surface-to-surface docking more secure and stable, the contact end of one of the first connection terminal 33 and the second connection terminal 21 can be configured as a retractable elastic structure. For example, the retractable contact end on the first connection terminal 33 is used for illustration. In contrast, the contact end on the second connection terminal 21 is fixedly mounted. The end face of the first connection terminal 33 is provided with a groove, within which the contact end is mounted. A spring is also provided within the groove, one end of the spring being connected to the groove and the other end to the contact end. The spring is compressed. When the first connection terminal 33 and the second connection terminal 21 are connected, the contact end on the first connection terminal 33 is ejected by the spring and connected to the contact end of the second connection terminal 21, achieving a secure and stable connection and ensuring stable signal transmission.

[0050] In one embodiment, to further reduce the difficulty of production and installation, the first connection terminal 33 and the second connection terminal 21 are connected by a cable. The two ends of the cable have terminals that adapt to the first connection terminal 33 and the second connection terminal 21. The two ends of the cable are respectively connected to the first connection terminal 33 and the second connection terminal 21. The first connection terminal 33 and the second connection terminal 21 can be connected by plug-in or surface-to-surface contact, and the two ends of the cable can be arranged correspondingly. The first connection terminal 33 and the second connection terminal 21 are connected by a cable, so that the first connection terminal 33 and the second connection terminal 21 do not need to be aligned for installation. A gap for connection is reserved between the first connection terminal 33 and the second connection terminal 21.

[0051] In one embodiment, there are two IO interface modules 30, which are installed side by side in an opening 11 of the host 10, or the host 10 is provided with two openings 11. The two IO interface modules 30 are equipped with different types of IO interface terminals 32. If one IO interface terminal 32 is damaged, the module where it is located can be replaced, and the other module does not need to be removed and can continue to be used.

[0052] The IO interface terminals 32 may include a power interface terminal for connecting to an external power supply, a USB interface terminal for communicating with an external storage device, an HDMI interface terminal and a VGA interface terminal for transmitting video and audio data of a portable ultrasound device, a probe interface terminal for adapting to an ultrasound probe, an ECG interface terminal for adapting to an electrocardiograph, a video printer interface terminal for outputting ultrasound images 7 for printing, and an S-VIDEO interface terminal for outputting ultrasound images to, for example, a hospital workstation, etc. One or more of the above-mentioned IO interface terminals 32 may be integrated on one IO interface module 30.

[0053] The IO interface terminals 32 can be divided into commonly used IO interface terminals and uncommonly used IO interface terminals based on their frequency of use. For example, the power interface terminal and the probe interface terminal are commonly used IO interface terminals and must be connected every time they are used. The ECG interface terminal, the video printer interface terminal, and the S-VIDEO interface terminal are uncommonly used IO interface terminals and are only connected in special usage scenarios. Commonly used IO interface terminals are grouped together on one IO interface module 30, while uncommonly used IO interface terminals are grouped together on another IO interface module 30. Commonly used IO interface terminals are used more frequently and are more likely to be damaged. Therefore, grouping commonly used IO interface terminals on one IO interface module 30 allows only that IO interface module 30 to be replaced. The IO interface module 30 containing uncommonly used IO interface terminals does not need to be disassembled and can continue to be used, reducing replacement costs.

[0054] In other embodiments, the IO interface terminals 32 can be divided into general IO interface terminals and ultrasound-related IO interface terminals according to their functions. For example, the probe interface terminal, ECG interface terminal, video printer interface terminal and S-VIDEO interface terminal are ultrasound-related IO interface terminals, and the power interface terminal, USB interface terminal, HDMI interface terminal and VGA interface terminal are general IO interface terminals. The division by function is convenient for users to plug in and use, and can also reduce costs.

[0055] In other embodiments, IO interface terminals can be divided into fragile IO interface terminals and non-fragile IO interface terminals based on their fragility. Fragile IO interface terminals are grouped together in a single IO interface module, while non-fragile IO interface terminals are grouped together in a single IO interface module. By grouping IO interface terminals based on their fragility, it is possible to minimize the need to replace the entire IO interface module due to the fragility of individual terminals, thereby helping to control the maintenance costs of portable ultrasound equipment. For example, since the S-VIDEO interface terminal and the video printer interface terminal are very susceptible to damage, these two interface terminals can be grouped together separately.

[0056] In other embodiments, three or more IO interface modules 30 may be provided, and one IO interface module 30 may be installed with only one IO interface terminal 32 , and a corresponding number of second connection terminals 21 may be provided on the mainboard 20 .

[0057] In one embodiment, the circuit board 31 is a multi-layer design. For example, the circuit board 31 may include a power supply layer and a routing layer. The routing layer of the circuit board 31 includes one or more routing lines from each IO interface terminal to the first connection terminal 33. For the probe interface terminal, the routing layer of the circuit board 31 is correspondingly provided with a probe routing line connected to the probe interface terminal and the first connection terminal 33. The probe routing line is used to transmit the probe signal obtained by the probe interface terminal to the first connection terminal 33. The probe signal can be, for example, an image signal scanned and imaged using a portable ultrasound device. For the ECG interface terminal, the routing layer of the circuit board 31 is provided with an ECG routing line connected to the ECG interface terminal and the first connection terminal 33. The ECG routing line is used to transmit the electrocardiogram signal obtained at the ECG interface terminal to the first connection terminal 33.

[0058] The probe signal is relatively weak and susceptible to external interference. In one embodiment, the circuit board 31 of the present invention further includes a ground layer, which surrounds part or all of the probe traces of the trace layer to reduce the signal interference suffered by the probe signal. In one embodiment, the present invention provides grounding protection at all connections related to obtaining the probe signal to reduce the signal interference suffered by the probe signal through a good grounding method. For example, grounding protection is provided at the connection between the probe trace and the probe interface terminal, the connection between the probe trace and the first connection terminal, and the connection between the first connection terminal and the second connection terminal. Grounding protection can also be provided at the connection between the ultrasonic probe and the probe interface terminal. Those skilled in the art can select a specific grounding method according to actual needs, and the present invention does not impose any special restrictions.

[0059] In one embodiment, at least one IO interface module of the present invention includes a probe interface module, on which a probe interface terminal is separately provided. The probe interface module is then isolated from other IO interface modules by other shielding technologies to reduce interference of other signals on the probe signal.

[0060] In one embodiment, given that the degree of probe signal attenuation is related to signal transmission distance, the present invention also proposes minimizing probe signal attenuation by controlling the total length of the probe traces on the circuit board 31. For example, the probe interface terminals on both sides of the circuit board 31 can be arranged roughly aligned with the first connection terminal 33, which facilitates controlling the total length of the probe traces from the probe interface terminals to the first connection terminal 33. In one embodiment, through comprehensive control of the circuit layout on the circuit board 31, the total length of the probe traces is kept as short as possible, while ensuring that there are no or very few flying leads in the circuit board area where the probe traces are located.

[0061] In one embodiment, Figure 2 and Figure 3 As shown, to better install the IO interface module 30, the IO interface module 30 also includes a baffle 34. The baffle 34 is a rectangular structure that fits within the opening 11 of the host 10. The baffle 34 can block the opening 11, providing a sealing and locking effect. The baffle 34 is provided with at least one through-hole. The size, shape, and position of the through-hole correspond to the IO interface terminal of the IO interface module 30. After the IO interface terminal is installed on the circuit board 31, the connection terminal of the IO interface terminal 32 can be inserted into the through-hole of the baffle 34 and exposed through the through-hole of the baffle 34. Preferably, the baffle 34 is connected to the circuit board 31 perpendicularly, making the structure of the IO interface module 30 more stable. The IO interface module 30 is inserted into the host 10, and the baffle 34, circuit board 31, and IO interface terminal 32 are all located within the host 10. The surface of the baffle 34 is flush with the side of the host, and the connection terminal of the IO interface terminal 32 is exposed on the surface of the baffle 34.

[0062] In one embodiment, first clips extending toward the circuit board 31 are provided on both sides of the baffle 34. A second clip is provided near the opening 11 in the host 10. The first and second clips are adapted to fit together, and the baffle 34 is inserted and mounted in the host 10 through the engagement of the first and second clips. The first clip is a buckle with a certain degree of elasticity, and the second clip is a slot. The first clip and the baffle 34 are integrally formed, and the second clip is integrally formed with the host 10. When the baffle 34 is inserted into the opening of the host 10, the buckle elastically deforms and snaps into the slot to achieve a snap connection. During disassembly, it can be disassembled by simply prying with a tool. The structures of the first and second clips are interchangeable, and a snap connection can also be achieved.

[0063] In order to better remove the baffle 34, a notch or a sink is provided on the edge of the baffle 34 or the edge of the opening 11 of the host 10. The notch or sink forms a gap between the baffle 34 and the opening 11 of the host 10, which can be used by a workpiece to pry and remove the baffle 34.

[0064] In addition to the above-mentioned clamping method, the first clamping member and the second clamping member may be connected in other ways, such as a buckle structure or a lock structure.

[0065] In one embodiment, a pop-up mechanism is provided inside the host 10, which is similar to the pop-up mechanism of a mobile phone card. The pop-up mechanism has a pop-up end and a trigger end, which are connected by a connecting rod or other adapter. The baffle 34 is connected to the pop-up end of the pop-up mechanism. A through hole is provided on the host 10 or the baffle 34, and the trigger end of the pop-up mechanism is aligned with the through hole. After a needle is inserted into the through hole to squeeze the trigger end of the pop-up mechanism, the trigger end will drive the pop-up end to pop out the baffle 34, thereby facilitating the disassembly of the IO interface module 30.

[0066] In one embodiment, the baffle 34 is detachably mounted on the host 10 by screws, which is convenient for assembly and disassembly.

[0067] In one embodiment, a second display screen 41 is installed on the surface of the flip cover 40 facing away from the main unit 10. The second display screen 41 is smaller in size than the first display screen. The second display screen 41 is connected to the main board 20 and is used to display the power level and power on / off status of the portable ultrasound device. When the flip cover 40 is incorporated into the main unit 10, the second display screen 41 can be used to understand the power level and whether the main unit 10 is in the power on, power off or standby state. There is no need to open the flip cover 40 for operation, which is convenient for users to use.

[0068] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, the above specific embodiments can be modified.
