[0004] The technical problem to be solved by this utility model is to provide a probe and diagnostic device to address the issues that existing ultrasound diagnostic equipment is large in size, has poor portability, and has a limited range of applications.

[0005] To address the aforementioned problems, one embodiment of this utility model provides a probe, including a main body, a housing, a battery assembly, a control board, and buttons; The main body is located at one end of the outer shell and is electrically connected to the control board; The outer shell has an internal accommodating cavity; The battery assembly and the control board are disposed in the accommodating cavity, and the battery assembly and the control board are arranged sequentially along the first direction; The battery assembly includes a battery, a fixing member, and a button panel. Along the first direction, the fixing member has a first side and a second side opposite to each other. The battery is fixedly connected to the first side of the fixing member, and the button panel is fixedly connected to the second side of the fixing member. The battery is located between the control board and the button panel. The battery and the keypad are electrically connected to the control board, and the control board is provided with a communication module for communicating with external devices; The button is located on the outer wall of the housing and is positioned opposite to the keypad along the first direction. The button is used to trigger the keypad.

[0006] Optionally, the fastener includes a mounting plate, a first limiting plate, and a second limiting plate. The mounting plate has a first side and a second side. One end of the mounting plate is connected to the first limiting plate, and the other end of the mounting plate is connected to the second limiting plate. Along the first direction, the first limiting plate and the second limiting plate are located on the same side of the mounting plate, and the first limiting plate, the mounting plate and the second limiting plate form a limiting groove, and the battery is arranged in the limiting groove.

[0007] Optionally, the keypad is provided with mounting holes, and the second side of the mounting plate is provided with a protrusion, which is inserted into the mounting holes; The battery is adhered to the first side of the mounting plate.

[0008] Optionally, the first limiting plate is provided with a first connecting plate, the first connecting plate is provided with a first connecting hole, and the outer shell is provided with a second connecting hole; the first connecting hole and the second connecting hole correspond to each other and are used to connect the first connecting plate and the outer shell; The second limiting plate is provided with a second connecting plate, the second connecting plate is provided with a third connecting hole, and the outer shell is provided with a fourth connecting hole. The third connecting hole corresponds to the fourth connecting hole and is used to connect the second connecting plate and the outer shell.

[0009] Optionally, the outer casing includes a first housing and a second housing, the first housing having a first accommodating space, the second housing having a second accommodating space, the first accommodating space and the second accommodating space communicating to form the accommodating cavity; One end of the first housing and one end of the second housing form an installation space, and the installation space communicates with the receiving cavity; One end of the main body, near the outer casing, is located in the mounting space and connected to the outer casing.

[0010] Optionally, the communication module includes a WiFi module, which is electrically connected to the control board; The accommodating cavity is equipped with an antenna, which is fixed to the inner wall of the outer shell and electrically connected to the control board; Along the first direction, the antenna, the control board, the battery, and the keypad are arranged in sequence.

[0011] Optionally, the communication module includes a USB interface, which is located at the other end of the housing and is electrically connected to the control board.

[0012] Optionally, the outer wall of the housing is provided with an indicator light, the accommodating cavity is provided with an indicator light panel, and the button panel and the indicator light are both electrically connected to the indicator light panel; Along the first direction, the control board, the indicator board, and the indicator lights are arranged in sequence.

[0013] Optionally, the button is integrally formed with the housing.

[0014] According to the probe provided in this embodiment, the probe body is responsible for the core acoustic-electric conversion at one end of the outer shell. That is, after an external device (such as a tablet computer) issues a command via the control board, it emits ultrasonic waves and receives the echoes returned from human tissue, converting them into electrical signals. These electrical signals are then preliminarily processed by the control board and transmitted to an external device via wired or wireless means for imaging analysis. The internal structure of this application adopts a highly integrated stacking scheme: the battery assembly serves as the energy core, and its unique "sandwich" structure is key—with a fixing component as the central skeleton, the battery is fixed on one side, and the button panel is fixed on the other, allowing the battery to be cleverly suspended between the control board and the button panel. The fixing component enables bidirectional integrated installation of the battery and button panel, significantly reducing internal space occupation, effectively reducing probe size, improving portability, and expanding the applicability in scenarios such as outdoor emergency rescue and primary healthcare. Simultaneously, the buttons on the outer shell face the button panel, allowing user operations to be directly transmitted to the button panel via the buttons, and then transmitted to the control board via circuitry, thereby controlling the device. Through this compact layout, the entire system minimizes its overall size while ensuring the normal operation of all electronic functions. This application utilizes a stacked battery assembly that integrates the battery, mounting hardware, and control panel into a single unit, arranged side-by-side with the control board. This design maximizes the use of the probe's internal space, significantly reducing its overall size and creating a portable, handheld ultrasound probe. This allows the device to be easily carried to various scenarios, including bedside, emergency, field, and primary healthcare facilities, greatly expanding its applicability. Furthermore, the integrated structure simplifies internal cable connections and assembly, improving production efficiency and structural reliability. Therefore, this invention provides excellent portability while ensuring stability and ease of use, meeting the urgent needs of modern medicine for mobile and precise diagnosis.

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and 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 of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 8 As shown, one embodiment of this utility model provides a probe, including a main body 1, a shell 2, a battery assembly 4, a control board 3, and a button 5; The main body 1 is located at one end of the outer casing 2 and is electrically connected to the control board 3; The outer casing 2 has an internal accommodating cavity 6; The battery assembly 4 and the control board 3 are disposed in the accommodating cavity 6, and the battery assembly 4 and the control board 3 are arranged sequentially along the first direction. The battery assembly 4 includes a battery 41, a fixing member 42 and a button plate 43. Along the first direction, the fixing member 42 has a first side and a second side opposite to each other. The battery 41 is fixedly connected to the first side of the fixing member 42, and the button plate 43 is fixedly connected to the second side of the fixing member 42. The battery 41 is located between the control board 3 and the button plate 43. Battery 41 and button board 43 are electrically connected to control board 3 respectively. Control board 3 is equipped with a communication module for communicating with external devices. Button 5 is located on the outer wall of housing 2 and is positioned opposite to keypad 43 along a first direction. Button 5 is used to trigger keypad 43. By arranging battery assembly 4 and control board 3 sequentially along the "first direction" inside housing 2 and adopting an integrated battery assembly 4 design, the internal space utilization of the probe is significantly improved, the overall volume is reduced, and the portability of the device is enhanced. Fixture 42 connects battery 41 and keypad 43, achieving structural stability, easy assembly, and convenient maintenance. Button 5 is located on the outer wall of housing 2 and is opposite to keypad 43. When the user presses button 5 on housing 2, it triggers the microswitch on keypad 43, thereby sending commands such as start, mode switching, or image freeze to control board 3. Fixture 42, through its bidirectional design of "battery 41 on one side and keypad 43 on the other side," allows both to share the same fixing carrier, eliminating the need for separate installation structures. Battery 41 and keypad 43 are constrained on both sides of fixture 42 and can only be "stacked" along the first direction, rather than being "laterally dispersed" within the accommodating cavity. This design avoids the disorderly distribution of components occupying lateral space, allowing internal components to be more concentrated and significantly reducing the overall volume. The first direction is for attachment. Figure 3 , Figure 5 The probe in this application is an ultrasound probe, and the control board 3 communicates with external devices via a communication module. Its operation is as follows: the control board 3 inside the probe drives the transducer array in the main body 1 to emit ultrasonic waves. After the ultrasonic waves enter human tissue, reflection echoes are generated due to differences in acoustic impedance between different tissues. The probe receives the echo signals, which are then pre-amplified, filtered, and converted from analog to digital. The DSP then performs beamforming, image reconstruction, and other processing to generate ultrasound image data. Subsequently, the image data is transmitted to external devices (such as smartphones, tablets, or laptops) via a data cable or the built-in WiFi module. It is understood that the control board 3, main body 1, battery 41, button board 43, WiFi module, and corresponding circuit connections in the probe are existing mature technologies used to drive the probe, process echo signals, and wirelessly transmit data; these will not be elaborated upon in this application. Compared to traditional desktop devices, this probe, through its innovative internal structural layout, successfully develops a small, lightweight, easy-to-operate, and portable handheld color Doppler ultrasound probe, providing an efficient and reliable solution for mobile healthcare, remote diagnosis, and instant ultrasound examination.

[0023] like Figure 7 and Figure 8 As shown, in one embodiment, the fastener 42 includes a mounting plate 421, a first limiting plate 422 and a second limiting plate 423. The mounting plate 421 has a first side and a second side. One end of the mounting plate 421 is connected to the first limiting plate 422, and the other end of the mounting plate 421 is connected to the second limiting plate 423. Along the first direction, the first limiting plate 422 and the second limiting plate 423 are located on the same side of the mounting plate 421. The first limiting plate 422, the mounting plate 421, and the second limiting plate 423 form a limiting groove 424, in which the battery 41 is arranged. The battery 41 and the button plate 43 are respectively mounted on the first and second sides of the mounting plate 421. Together with the first limiting plate 422 and the second limiting plate 423 at both ends, the mounting plate 421 forms the limiting groove 424, and the battery 41 is precisely embedded in the limiting groove 424. This structure can mechanically limit the displacement of the battery 41 along the first direction and the vertical direction, preventing the battery 41 from becoming loose due to vibration during probe movement or use, ensuring the stability of the electrical connection between the battery 41 and the control board 3, and reducing equipment failures caused by poor contact. The integrated design of the limiting groove 424 (mounting plate 421 + side limiting plates) provides dedicated space for the battery 41 and, through its "embedded" structure, eliminates the need for additional fixing components (such as screws, clips, etc.). This simplifies the assembly process while compressing internal space, helping to improve assembly efficiency and reduce production costs during mass production. Furthermore, the connection between the mounting plate 421 and the side limiting plates forms a U-shaped, stable frame that not only supports the weight of the battery 41 but also disperses external impact forces on the probe housing 2, indirectly protecting core components such as the control board 3 and button board 43 within the accommodating cavity 6, extending the equipment's lifespan. This design is particularly suitable for outdoor and grassroots applications where frequent movement or complex environments are possible.

[0024] like Figure 7 and Figure 8 As shown, in one embodiment, the button plate 43 is provided with a mounting hole 431, and the second side of the mounting plate 421 is provided with a protrusion 427, which is inserted into the mounting hole 431. The battery 41 is bonded to the first side of the mounting plate 421. The button plate 43 is inserted into the protrusion 427 on the second side of the mounting plate 421 through the mounting hole 431, achieving quick positioning and mechanical fixation. This insertion structure ensures that the button plate 43 is precisely aligned with the button 5 along the first direction (avoiding trigger failure due to misalignment), while limiting the displacement of the button plate 43 in the direction perpendicular to the first direction, reducing loosening caused by vibration or pressing the button 5 during use, ensuring the reliability of the electrical connection between the button plate 43 and the control board 3, and improving the stability of the operation response. The battery 41 is fixed to the first side of the mounting plate 421 by bonding. Compared with rigid connections such as screws, the flexible properties of the adhesive can buffer the impact of vibration on the battery 41, and it also eliminates the need for additional fastening components, reducing the space occupied in the accommodating cavity 6 (adapting to the miniaturized design of the probe); at the same time, the bonding process is simple to operate, which can improve the assembly efficiency during mass production and reduce labor costs. Both plug-in and adhesive connection methods do not require complex additional structures, allowing the button board 43, mounting plate 421, and battery 41 to form an "integrated module" that is closely arranged along the first direction, further compressing the overall volume of the battery assembly 4 and reserving more space for the layout of components such as the control board 3 in the accommodating cavity 6, thus helping the probe achieve better miniaturization and portability.

[0025] like Figure 7 and Figure 8 As shown, in one embodiment, the first limiting plate 422 is provided with a first connecting plate 425, the first connecting plate 425 is provided with a first connecting hole 4251, and the outer shell 2 is provided with a second connecting hole; the first connecting hole 4251 corresponds to the second connecting hole and is used to connect the first connecting plate 425 and the outer shell 2; The second limiting plate 423 is provided with a second connecting plate 426, and the second connecting plate 426 is provided with a third connecting hole 4261. The outer shell 2 is provided with a fourth connecting hole, and the third connecting hole 4261 corresponds to the fourth connecting hole for connecting the second connecting plate 426 and the outer shell 2. The first connecting plate 425 of the first limiting plate 422 is connected to the second connecting hole of the outer shell 2 through the first connecting hole 4251, and the second connecting plate 426 of the second limiting plate 423 is connected to the fourth connecting hole of the outer shell 2 through the third connecting hole 4261, forming a "symmetrical fixed at both ends" structure. At the same time, the control plate 3 is fixed on the outer shell 2. This design can firmly anchor the fixing component 42 (and the battery 41 and button plate 43 assembled on it) in the housing cavity 6 of the outer shell 2, avoiding overall loosening of the probe under movement, use or vibration environment, ensuring the relative position stability of the battery 41, button plate 43 and control plate 3, and ensuring the reliability of electrical connection and signal transmission. The symmetrically distributed connection points (with the connecting plates at both ends fixed to the outer shell 2 respectively) can evenly distribute external impact forces (such as drops and collisions) to the outer shell 2 and the fixing member 42, reducing component deformation or damage caused by local stress concentration. In particular, it protects core components such as the control board 3 and battery 41 inside the accommodating cavity 6, extending the service life of the equipment and adapting it to scenarios that may face complex environments, such as outdoor emergency rescue. The corresponding design of the connection holes provides a precise positioning benchmark for the assembly of the fixing member 42 and the outer shell 2, avoiding positional deviations during manual assembly and ensuring the uniformity of the relative positions of components such as the battery assembly 4 and the control board 3 in each device. This, in turn, ensures the alignment accuracy of the button 5 and the button plate 43 (avoiding trigger failure) and the stability of the electrical connections of each component, which is beneficial for quality control during mass production and reduces the defect rate. In addition, the detachable connection achieved through the connection holes (such as screw holes) facilitates the disassembly and assembly of internal components of the probe (such as replacing the battery 41 and repairing the button plate 43) without damaging the structure of the outer shell 2 or the fixing member 42, reducing maintenance costs and improving the reusability of the equipment.

[0026] like Figure 3 and Figure 6 As shown, in one embodiment, the outer shell 2 includes a first shell 21 and a second shell 22. The first shell 21 has a first accommodating space 61, and the second shell 22 has a second accommodating space 62. The first accommodating space 61 and the second accommodating space 62 communicate with each other to form an accommodating cavity 6. One end of the first housing 21 and one end of the second housing 22 enclose each other to form an installation space 23, and the installation space 23 is connected to the accommodating cavity 6; One end of the main body 1, near the outer shell 2, is located in the mounting space 23 and connected to the outer shell 2. Button 5 is located in the first shell 21. The outer shell 2 is divided into a first shell 21 and a second shell 22, each forming a connected first and second accommodating space 62 (together constituting the accommodating cavity 6). This split structure facilitates the pre-installation of internal components such as the battery pack 4 and control board 3 into the two shells, followed by assembly by closing the shells. Compared to a one-piece outer shell 2, this design makes it easier to precisely install complex components, significantly reducing assembly difficulty and improving production efficiency. One end of the first shell 21 and the second shell 22 encloses the mounting space 23. The end of the main body 1, near the outer shell 2, is located in this space and connected to the outer shell 2. This "enclosed" structure firmly fixes the main body 1 (the core component of ultrasonic testing), preventing the main body 1 from shifting or loosening due to force when the probe contacts the human body, ensuring the accuracy of ultrasonic wave transmission and reception, and improving the stability of diagnostic imaging. After the split outer shell 2 is closed, the sealing design (such as sealing rings and snap-fit) enhances the airtightness of the accommodating cavity 6, reducing the entry of external dust and liquids (such as coupling agents and sweat) into the interior, and protecting electronic components such as the control board 3 and battery 41 from corrosion. At the same time, the enclosure structure of the installation space 23 on the main body 1 can also buffer the impact of external collisions on the main body 1, extending the service life of core components. If it is necessary to repair or replace internal components (such as battery 41, control board 3) or the main body 1, the target component can be quickly accessed by disassembling the first and second shells 22 without damaging the overall structure of the outer shell 2, reducing maintenance costs and improving the maintainability and reusability of the equipment.

[0027] like Figure 3 As shown, in one embodiment, the communication module includes a WiFi module, which is electrically connected to the control board 3; The accommodating cavity 6 is equipped with an antenna 7, which is fixed to the inner wall of the outer shell 2 and electrically connected to the control board 3; Along the first direction, antenna 7, control board 3, battery 41, and button board 43 are arranged sequentially. Control board 3 can communicate with external devices via WiFi module. The electrical connection between antenna 7 and control board 3 enhances signal transmission and reception capabilities, ensuring a more stable WiFi connection between the probe and external devices (such as tablets and mobile phones), avoiding image transmission interruptions or disconnections due to weak signals, and ensuring the continuity of the diagnostic process. Arranging antenna 7, control board 3, battery 41, and button board 43 sequentially along the first direction creates a "linear and compact layout" of wireless components (antenna 7, WiFi module), power supply components (battery 41), and operation components (button board 43), avoiding horizontal overlap and space occupation by each component within the accommodating cavity 6. This orderly arrangement further compresses the overall size of the probe, meeting the core requirement of "compact and portable" handheld color ultrasound equipment, while also facilitating component positioning during assembly and improving production efficiency. The antenna 7 is fixed to the inner wall of the housing 2, rather than being directly attached to the control board 3 or the battery 41. This reduces the impact of internal component vibration (such as when the probe moves) on the position of the antenna 7 and avoids signal fluctuations caused by the offset of the antenna 7. At the same time, the inner wall of the housing 2 can provide a stable mounting base for the antenna 7, reduce the risk of damage to the antenna 7 from external impacts, and extend the service life of the wireless transmission components.

[0028] like Figure 1 As shown, in one embodiment, the communication module includes a USB interface, which is located at the other end of the housing 2. The USB interface 8 is electrically connected to the control board 3. The control board 3 is connected to an external device via the USB interface 8 and a data cable. The housing 2 is provided with a USB protective cover, which is used to cover the USB interface 8. The USB interface added to the housing 2 is electrically connected to the control board 3, adding a "USB data cable connection" option to the probe in addition to WiFi wireless connection. When the WiFi signal is weak or unstable (such as in complex medical environments) or the device needs emergency power, the user can connect to an external device via the data cable, which not only ensures the stability of signal transmission (avoiding wireless disconnection affecting diagnosis) but also replenishes the probe's power, adapting to more clinical usage scenarios. The USB protective cover on the housing 2 can be closed when the interface is not in use, effectively preventing external dust and liquids (such as ultrasound coupling agents and disinfectants) from entering the interface, avoiding malfunctions such as poor contact and short circuits caused by contamination; at the same time, it can prevent oxidation of the interface's metal contacts or damage from physical impacts, significantly improving the durability of the USB interface and reducing later maintenance costs. The USB interface is integrated into one end of the outer shell 2, with a compact layout that does not increase the size of the probe, meeting the core requirements of "small and lightweight" handheld devices. The protective cover can adopt a flip-top or snap-on design, which is simple to open and close. Users can quickly switch between "use / protection" status without the need for tools, without affecting the efficiency of the diagnosis and treatment process.

[0029] like Figure 1, 3 and Figure 5 As shown, in one embodiment, the outer wall of the housing 2 is provided with an indicator light 9, the accommodating cavity 6 is provided with an indicator light board 10, and the button board 43 and the indicator light 9 are both electrically connected to the indicator light board 10. Along the first direction, the control board 3, indicator light board 10, and indicator light 9 are arranged sequentially. Indicator light board 10 is fixed to the outer casing 2, and indicator light 9 is electrically connected to indicator light board 10. The button board 43 is also connected to indicator light board 10. The device status (such as power on / off, WiFi / USB connection success / failure, battery level, etc.) can be fed back in real time through the color and flashing mode of indicator light 9. Users do not need to look at the external device; they can quickly determine the device's operating status simply by looking at the indicator light 9 on the outer wall of casing 2, reducing operational errors. This is especially suitable for scenarios requiring efficient operation, such as emergency care and primary care. The sequential arrangement of control board 3, indicator light board 10, and indicator light 9 along the first direction creates a linear and compact layout between the status feedback components (indicator light 9 and indicator light board 10) and the core functional components (control board 3). This ensures that each component operates independently and further reduces the probe size, meeting the core requirement of "compact and portable" handheld color ultrasound equipment. Meanwhile, the indicator light board 10 serves as an intermediate connecting component, electrically connected to the button board 43 and the indicator light 9 respectively, avoiding complex wiring between the indicator light 9 and the control board 3 and reducing cross-interference of the lines; at the same time, the indicator light board 10 is fixed in the accommodating cavity 6, which ensures stable position, reduces poor contact of the lines caused by vibration, and ensures the reliability of the status feedback function.

[0030] In one embodiment, button 5 is integrally formed with housing 2. In traditional split designs, button 5 needs to be mounted on housing 2 using independent fasteners 42 such as screws, clips, and brackets. These fasteners 42 not only occupy internal space in the accommodating cavity 6, but may also cause layout conflicts with core components such as battery 41 and control board 3. Integral molding directly integrates the structure of button 5 with housing 2 into a whole, eliminating the need for additional fasteners. This is equivalent to "saving" the space originally occupied by fasteners 42, allowing housing 6 to reserve more space for key components such as battery 41 and control board 3, or further compressing the overall volume of the probe without changing the component size. Specifically, button 5 can be integrally molded into housing 2 using a plastic process.

[0031] like Figure 6As shown, in one embodiment, the inner wall of the outer shell 2 has a groove corresponding to the button 5. The button 5 includes a power button and a function button. Two pressure plates 51 are provided in the groove. One pressure plate 51 corresponds to the power button, and the other pressure plate 51 corresponds to the function button. The pressure plates 51 serve to support the button and the button plate 43 and are electrically connected to the button plate 43. The power button is specifically responsible for turning the probe on, off, or into sleep mode, while the function button corresponds to specific operations (such as switching ultrasound modes, freezing images, adjusting parameters, etc.). The two have a clear division of labor. Users do not need to go through complex menus or rely on external devices. They can complete the core operations using only the two buttons on the probe itself. This is especially suitable for scenarios requiring rapid response, such as emergency care and primary care, reducing operational errors. The power button and function button can be manufactured as a single piece with the outer shell 2, without the need to add a separate fixing part 42 or increase the size of the outer shell 2 for the added button. The mold can directly reserve the structural positions of the two buttons on the outer wall of the outer shell 2. The two buttons are arranged compactly along the surface of the outer shell 2 (such as adjacent to each other vertically or horizontally), which not only expands the functionality but also maintains the compact size of the probe, meeting the portability requirements of handheld devices. Independent power and function keys can be distinguished by different pressing feedback (such as key travel and force) or visual markings (such as shape and texture), reducing the probability of users mistakenly operating the power key as a function key (for example, avoiding accidental power button activation during inspection, which could lead to device shutdown). Simultaneously, the separate design reduces the risk of a single button malfunction causing "all operations to fail," improving device stability. Two pressure plates 51 within the groove correspond to the switch button (such as the power button) and the function key, respectively, precisely connecting the button (outer wall of the housing 2) and the keypad 43 (within the accommodating cavity 6), forming a stable triggering link of "button - pressure plate 51 - keypad 43." The pressure plate 51's bearing function prevents misalignment or poor contact when the button is directly pressed, ensuring accurate transmission of commands with each press (such as precise power-on or mode switching), reducing operational interruptions due to trigger failure, and is particularly suitable for the high accuracy requirements in medical diagnostics. The recessed design houses the pressure plate 51 within the inner wall of the housing 2, eliminating the need for a separate mounting slot for the pressure plate 51 within the accommodating cavity 6. Furthermore, the two pressure plates 51 are compactly arranged within the same recess, achieving independent triggering of the switch button and function button (without interference), while avoiding the need to expand the size of the housing 2 or occupy space for core components (battery 41, control board 3) due to functional partitioning. This perfectly meets the design requirements for probe miniaturization and portability. The pressure plate 51 is hidden within the recessed inner wall of the housing 2, rather than being directly exposed within the accommodating cavity 6. This reduces the impact of vibration or displacement of components such as the battery 41 and control board 3 on the pressure plate 51. Simultaneously, the recess prevents dust and fine debris from accumulating on the surface of the pressure plate 51 within the accommodating cavity 6, avoiding poor contact caused by debris, extending the lifespan of the triggering components, and ensuring long-term stable operation of the equipment.

[0032] According to the probe provided in this embodiment, the probe body 1 is responsible for the core acoustic-electric conversion at one end of the outer shell 2. That is, after an external device (such as a tablet computer, corresponding to the host in the background art) issues a command through the control board 3, it emits ultrasonic waves and receives the echoes returned from human tissue, converting them into electrical signals. After preliminary processing by the control board 3, these electrical signals are transmitted to an external device for imaging analysis via wired or wireless means. The internal structure of this application adopts a highly integrated stacking scheme: the battery assembly 4 serves as the energy core, and its unique "sandwich" structure is key—with the fixing member 42 as the central skeleton, the battery 41 is fixed on one side, and the button panel 43 is fixed on the other side, so that the battery 41 is cleverly suspended between the control board 3 and the button panel 43. The bidirectional integrated installation of the battery 41 and the button panel 43 is achieved through the fixing member 42, which greatly reduces the internal space occupation, effectively reduces the probe volume, improves portability, and expands the applicability of outdoor emergency rescue, primary care, and other scenarios. Meanwhile, the button 5 located on the outer casing 2 faces the keypad 43. User operations are directly transmitted to the keypad 43 via the button 5, and then to the control board 3 via the circuit, thereby controlling the device. This compact layout ensures the normal operation of all electronic functions while minimizing the overall size of the system. This application integrates the battery 41, fixing member 42, and keypad 43 into a stacked battery assembly 4, arranged side-by-side with the control board 3. This design maximizes the use of the probe's internal space, significantly reducing the overall size of the probe and creating a portable, handheld ultrasound probe. This allows the device to be easily carried to various scenarios such as bedside, emergency rooms, field, and primary healthcare institutions, greatly expanding its applicability. Furthermore, the integrated structure simplifies internal cable connections and assembly processes, improving production efficiency and structural reliability. Therefore, this invention provides excellent portability while ensuring the stability and ease of use of the device, meeting the urgent needs of modern medicine for mobile and precise diagnosis.

[0033] Furthermore, this utility model provides a diagnostic device comprising an external device and the probe described in the above embodiment, with the probe connected to the external device via a signal connection. The device uses a miniaturized probe as its core functional carrier (integrating ultrasound signal acquisition, power supply, and wireless transmission components), paired with an external device (tablet, mobile phone, etc.) as a display and operation platform, replacing the traditional desktop / laptop host structure. It can be easily carried to outdoor emergency care, primary care clinics, and remote area outreach programs, overcoming the limitation of traditional devices being "fixed to use only in the department." On one hand, the external device can reuse existing tablets or mobile phones used by medical staff or medical institutions, eliminating the need for additional dedicated display equipment and significantly reducing overall procurement costs. On the other hand, the probe's simplified structure (no redundant components) makes subsequent maintenance (such as battery replacement and cleaning) more convenient, with lower maintenance costs than traditional devices. Simultaneously, the probe's integrated WiFi / USB dual connection allows for rapid and stable signal connection with the external device, avoiding the complex wiring and slow startup issues of traditional devices. The large-screen display of the external device (such as a tablet) clearly presents ultrasound images and supports image storage, annotation, and transmission (such as remote consultation), improving diagnostic efficiency. Meanwhile, the stable design of the probe's internal components (battery 41, control board 3, pressure plate 51, etc.) ensures the accuracy of ultrasound signal acquisition and transmission, with diagnostic results no less accurate than traditional equipment, meeting the reliability requirements of clinical diagnosis. During use, users need to install a dedicated ultrasound application (App) on the external device beforehand. This App (based on existing mature technology) is responsible for receiving, decoding, and displaying ultrasound images in real time, while also providing selection of multiple imaging modes such as B-mode, color Doppler, and spectral Doppler, as well as parameter adjustment functions. The probe of this application emits ultrasound waves, receives reflected signals, and after processing, transmits them to external devices such as mobile phones and tablets via WiFi or USB for image display, realizing B-mode imaging and blood flow analysis. The system supports two connection methods: one is a physical connection between the probe and the external device via USB data cable, which is plug-and-play and highly stable; the other is a wireless connection via WiFi. After the user turns on the probe power, they select the corresponding WiFi network name in the external device App to pair and connect, achieving wireless image transmission. After successful connection, the user applies ultrasound coupling gel to the examination area, places the probe firmly against the body surface for scanning, and the external device can then display real-time images of human tissue cross-sections for clinical diagnosis and blood flow analysis.
