Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular, to a portable ultrasonic detection device and a portable ultrasonic detection system. Background Art

[0002] Ultrasound imaging is a relatively cheap, safe and accurate examination method. The probes currently used in ultrasound examinations are mainly handheld, and during the examination, the probe needs to be placed against the skin. For some softer tissues (such as breast tissue), the shape may change as the probe is scanned during the examination, which makes it impossible to accurately image. In addition, different exploration angles and different users make ultrasound imaging very different, which is not conducive to the doctor's accurate grasp of the condition and location of the lesion.

[0003] Therefore, some ultrasound devices equipped with mechanical devices have appeared on the market. The mechanical devices can stably move the ultrasound probe to achieve the purpose of accurate imaging, which greatly reduces the skill requirements for users. To ensure that the tissue will not be displaced due to the movement of the ultrasound probe during the scanning process, a coupling piece can be set between the ultrasound probe and the part to be inspected to squeeze and position the part to be inspected, so that the position of the tissue remains unchanged during the inspection.

[0004] At present, this type of ultrasonic detection device that uses mechanical devices for scanning is usually a trolley type or a scanning bed type, which is large and bulky. Taking a trolley-type ultrasonic detection device as an example, the trolley is equipped with a mechanical arm, which presses the scanning component against the subject's breast. Since the mechanical arm is long and easily shaken when subjected to external force, a counterweight is set in the trolley to ensure stability during the inspection process. This further brings inconvenience to the equipment maintenance and transportation processes, and it is also more laborious for the operator to move it. Summary of the invention

DETAILED DESCRIPTION

[0044] In the following description, a large amount of details are provided so that the present application can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates the preferred embodiments of the present application, and the present application can be implemented without one or more such details. In addition, in order to avoid confusion with the present application, some technical features well known in the art are not described in detail.

[0045] In order to thoroughly understand the implementation of the present application, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present application is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the present application is described in detail below, but in addition to these detailed descriptions, the present application may also have other implementations.

[0046] The embodiment of the present application provides a portable ultrasonic detection device. The portable ultrasonic detection device according to the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0047] Taking the standard inspection form of the portable ultrasonic detection device of the present application as an example, during the inspection, the subject is usually in a supine position. The portable ultrasonic detection device can be placed vertically on the breast of the subject, or the portable ultrasonic detection device can be placed at a certain angle to the vertical direction (usually not more than ±15 degrees). For ease of description, the vertical direction ZZ, as well as the transverse direction XX and the longitudinal direction YY perpendicular to the vertical direction ZZ are defined. Among them, the transverse direction XX and the longitudinal direction YY are located on a horizontal plane and are perpendicular to each other.

[0048] like Figure 1 As shown, the portable ultrasonic detection device may include an ultrasonic probe 100 and a housing assembly 200. The housing assembly 200 defines a scanning cavity 210, and the ultrasonic probe 100 extends into the scanning cavity. Figure 5 , the detection surface 110 of the ultrasonic probe may face the opening 220. In the embodiment shown in the figure, the portable ultrasonic detection device is placed vertically. The detection surface 110 of the ultrasonic probe 100 may not extend out of the opening 220, in other words, the lowest point of the detection surface 110 is not lower than the lowest point of the opening 220. The ultrasonic probe 100 is movable along the scanning direction. In other embodiments, the detection surface of the ultrasonic probe 100 may also be flush with the opening 220, or protrude outside the opening 220.

[0049] The ultrasonic probe 100 is provided with array elements arranged in a predetermined direction, each array element can emit ultrasonic waves outward and receive reflected echoes. When the ultrasonic probe 100 does not move, the scanned area is close to a line. For example, the array elements in the ultrasonic probe 100 can be arranged horizontally along the transverse direction XX, and accordingly, the ultrasonic probe 100 can be moved along the longitudinal direction YY, so that the scanned area is rectangular. In other embodiments, the array element arrangement direction of the ultrasonic probe 100 may be different. For example, the ultrasonic probe 100 in which the internal array elements are arranged along the longitudinal direction YY can be moved horizontally along the transverse direction XX. In an embodiment not shown, the ultrasonic probe can also rotate around a point. In short, as long as the scanning area forms a surface. The shell assembly 200 can be constructed to form a rectangular scanning cavity, a circular scanning cavity or a scanning cavity of other shapes according to different scanning modes. In the specific embodiment shown in the figure, the shell assembly 200 forms a rectangular and closed scanning cavity 210. The ultrasonic probe 100 can be driven by a device such as a linear motor arranged in the shell assembly 200 and parallel to the scanning direction. In some embodiments, the scanning cavity 210 may not have a closed cross-section. Figure 5 As shown, the housing assembly 200 may include two independent and opposite faces, and the two faces are perpendicular to the scanning direction. The two housing assemblies 200 may be connected by a guide rail and / or a screw rod, and the ultrasound probe 100 moves along the guide rail or the screw rod in the scanning cavity 210 defined by the two opposite faces. In other embodiments, the housing assembly 200 with opposite faces may be connected to a top plate at its upper end or a bottom plate at its lower end so that the parts of the housing assembly 200 do not move relative to each other, thereby avoiding deformation of the scanning cavity 210.

[0050] The portable ultrasonic detection device may further include an ultrasonic coupling member 300. The ultrasonic coupling member 300 may be disposed at the bottom of the housing assembly 200, and the detection surface 110 of the ultrasonic probe 100 is opposite to the ultrasonic coupling member 300 and is movable across the ultrasonic coupling member 300. The ultrasonic coupling member 300 is sound-transmissive and is used to be pressed against the inspection site of the object, thereby positioning the relatively soft tissue. In this way, when the ultrasonic probe 100 is moved, the various parts of the tissue will not be displaced due to the friction of the ultrasonic probe 100, resulting in a part of the tissue being scanned repeatedly and another part of the tissue being missed, thereby affecting the accuracy of the diagnosis. The ultrasonic coupling member 300 may be constructed in a membrane, a mesh or a plate shape, and the ultrasonic coupling member 300 may be flat or have an appropriate curvature.

[0051] The portable ultrasonic detection device may include an ultrasonic host 20, which is disposed on the housing assembly 200 and electrically connected to the ultrasonic probe 100. The ultrasonic host 20 may analyze and process the raw data from the ultrasonic probe 100, and after processing, the raw data may be transmitted to the display 30 in the form of an image or data, or uploaded to a network database, an AI analysis model, a personal terminal, etc. The ultrasonic host 20 may be electrically connected to the ultrasonic probe 100 via a wired or wireless connection to obtain raw data and to supply power to the ultrasonic probe 100.

[0052] Figure 2-Figure 4 Three exemplary testing postures are respectively shown. Figure 2 The subject lies flat on his back and the portable ultrasound device is placed vertically above the subject's breast. Figure 1 Taking the portable ultrasonic detection device with a cubic structure as an example, the projection of the geometric center of the ultrasonic detection device on the horizontal plane can coincide with the nipple. Figure 3 A medial inspection posture is shown, where the subject can be raised sideways by a cushion so that the subject's body is 15° to the horizontal plane. Compared with tilting the portable ultrasonic detection device in the vertical direction for inspection, tilting the subject's body can effectively prevent the portable ultrasonic detection device from falling. The cushion is simplified in the figure. Figure 4 shows a lateral inspection posture, and Figure 3 The medial examination posture shown is relatively, and a pad can be placed on the other side of the subject's body to provide an inclination angle. Whether the subject's inclination angle meets the requirements can be further determined according to the indicator marks mentioned below.

[0053] The portable ultrasonic detection device may include a handle assembly 40, which may be arranged on opposite sides of the housing assembly 200 along the moving direction of the ultrasonic probe 100. In this way, when the operator carries the portable ultrasonic detection device through the handle assembly 40, the weight of the device can be dispersed on the two handle assemblies 40, and the center of gravity of the device is located between the handle assemblies 40 on both sides. In this way, the ultrasonic detection device will not rotate around the handle assembly 40 when moving because the handle assembly 40 is only arranged on one side. During the inspection process, the handle assemblies 40 on both sides can evenly transfer pressure to the ultrasonic coupling member 300, and different pressures can be applied to the two handle assemblies 40 so that the ultrasonic coupling member 300 is best fitted to the inspection site. The handle assembly 40 is used for the operator to press to apply pressure to the ultrasonic coupling member 300, and part of the pressure is also provided by the own gravity of the ultrasonic host 20, so that the pressure between the ultrasonic coupling member 300 and the object is within a preset pressure range. As described above, the portable ultrasonic detection device needs to apply sufficient pressure to the inspection site to ensure that the tissue of the inspection site will not be displaced during the inspection. Furthermore, the portable ultrasonic detection device itself may have a certain weight (about 2-5kg), and this weight is also applied vertically to the subject so that the pressure required for the inspection reaches the preset pressure range. In some embodiments, the portable ultrasonic detection device may be provided with a counterweight, which is detachably mounted on the main body of the portable ultrasonic detection device. For example, the main body of the portable ultrasonic detection device may have a weight of 3Kg, with a 2Kg counterweight or two 1Kg counterweights. This can avoid the operator having difficulty in moving the heavy portable ultrasonic detection device during the inspection, and can also enable the operator to press to reach the preset pressure range when placed on the subject's body. The preset pressure range meets the following conditions: it can ensure that the tissue in the inspection area will not move during the inspection, and will not cause a strong sense of discomfort to the subject.

[0054] In summary, the portable ultrasonic detection device is initially fixed and pressure is applied by the grip assembly 40, and the pressure is further ensured to meet the inspection requirements by its own weight, so that the portable ultrasonic detection device can achieve better inspection results without a bulky trolley and a heavy counterweight. The device is relatively simple to operate and can be used in scenarios with a high inspection frequency, such as community screening. It is more portable than equipment that is difficult to carry, such as trolleys and examination beds.

[0055] Exemplarily, the portable ultrasonic detection device may also include a display 30, which is mounted to the housing assembly 200 and electrically connected to the ultrasonic host 20. The display 30 can display the ultrasonic image processed by the ultrasonic host 20 for the operator to view. For example, the operator is a doctor, who can judge the inspection results based on the real-time image to confirm whether the current inspection results meet the diagnostic requirements. Puncture and other means can also be performed under ultrasonic guidance. Of course, the display 30 can also display other information, such as a preliminary analysis of the inspection results. Specifically, for example, the ultrasonic host 20 can preliminarily determine whether the position and applied pressure of the portable ultrasonic detection device meet the requirements, and give instructions during the inspection process so that the operator can correctly complete the acquisition to avoid the collected ultrasonic data not meeting the diagnostic requirements.

[0056] For example, the display 30 may be tilted upward in a rearward direction. Figure 2-Figure 4 As shown, during use, the operator usually stands at the side of the subject's body to operate. The subject lies on the bed, which makes the display 30 have a certain height. The inclined display 30 allows the operator to look directly at the display 30 in a standing state, avoiding seeing the wrong image due to the angle between the line of sight and the display 30, and there is no need to bend over or lean out to check, which is more convenient for the operator to use.

[0057] Exemplarily, the portable ultrasonic detection device may further include a power source, which is mounted to the housing assembly 200. The power source includes, but is not limited to, a battery and a power adapter. In other words, the portable ultrasonic detection device may be battery-powered. In other embodiments, the portable ultrasonic detection device may also be connected to a mains supply, and the ultrasonic host 20 and the ultrasonic probe 100 may be powered by a power adapter. The weight of the power source may also provide some pressure.

[0058] For example, the surface of the ultrasonic coupling element 300 in contact with the detection surface 110 may be called a coupling surface 310, and the coupling surface 310 may be smooth. The ultrasonic probe 100 may be in the form of a convex array, a concave array or a linear array, and correspondingly, the coupling surface 310 may also be constructed as a concave surface, a convex surface or a plane.

[0059] Exemplarily, the ultrasonic coupling member may include a bottom wall, a side wall extending upward from the bottom wall and surrounding the bottom wall, and an annular flange extending from the upper edge of the side wall to the outer peripheral side, and the annular flange is connected to the bottom of the shell assembly by a fastener. The fasteners can be used to fix the ultrasonic coupling member and the shell assembly more firmly, and a sealing ring can be provided between the two to ensure that the sound-conducting medium does not leak out of the scanning cavity 210.

[0060] Exemplarily, the portable ultrasonic detection device may further include a decorative frame 250, which may be mounted to the bottom of the housing assembly 200 and sleeved on the ultrasonic coupling member, with the bottom wall and side walls of the ultrasonic coupling member extending downwardly out of the decorative frame. The outer side surface of the decorative frame contracts inwardly from top to bottom so that the decorative frame covers the bottom surface of the annular flange. The decorative frame may be removably mounted to the housing assembly by snaps, magnetic suction or interference fit, thereby shielding the fasteners on the annular flange. This may make the portable ultrasonic detection device more beautiful on the one hand, and on the other hand protect the fasteners and prevent the burrs or edges of the fasteners from causing accidental damage to the subject. During use, the ultrasonic coupling member 300 is only coated with coupling agent on the portion protruding from the decorative frame 250 and in contact with the subject, so that the decorative frame may be prevented from contacting the subject and the coupling agent, and only the ultrasonic coupling member 300 needs to be replaced later, without replacing the decorative frame.

[0061] Exemplarily, the ultrasonic medium may be in liquid form. In order to avoid friction or pushing between the ultrasonic probe 100 and the ultrasonic coupling member 300 during movement, the size of the gap may be set slightly larger (e.g., 1 mm-2 mm), and the gap may not be uniform. At this time, a paste-like semi-solid ultrasonic medium is used, and bubbles may be drawn into the gap during the movement of the ultrasonic probe 100. The bubbles in the semi-solid are difficult to discharge, which may have a serious impact on the inspection. Preferably, an ultrasonic medium with good fluidity such as water or oil may be used. In this way, the ultrasonic medium can completely fill the gap, and the slow movement of the ultrasonic probe 100 will hardly cause bubbles to form in the gap.

[0062] Exemplarily, the shell assembly 200 can enclose a scanning cavity 210, the ultrasonic coupling member 300 is sealed and connected to the shell assembly 200, the bottom of the scanning cavity 210 has an opening 220, the ultrasonic coupling member 300 closes the opening 220, and the scanning cavity 210 is filled with a sound-conducting medium. As described above, compared with a coupling agent with poor fluidity, the use of a sound-conducting medium with good fluidity can improve the sound-conducting effect. The sealed connection between the ultrasonic coupling member 300 and the shell assembly 200 can avoid contamination caused by leakage of the sound-conducting medium.

[0063] like Figure 5 As shown, illustratively, the ultrasonic coupling member 300 may also include a coupling frame 310 and a coupling film 320, wherein the coupling frame 310 is mounted to the bottom of the housing assembly 200, and the coupling film 320 is fixed to the coupling frame 310 and closes the opening 220. During the inspection, the coupling agent may be applied to both side surfaces of the coupling film 320 to form an ultrasonic path of the detection surface 110--coupling agent--coupling film--coupling agent--subject. In some embodiments, the coupling frame 310 is fixed to the housing assembly 200 by fasteners, so that the coupling frame 310 and the housing assembly 200 are sealed. On this basis, a sound-conducting medium with good fluidity may be added to the coupling frame 310.

[0064] Exemplarily, the coupling frame 310 is detachably connected to the opening. This makes it easier to replace and maintain the ultrasonic coupling member 300. In some embodiments, the coupling frame 310 may be provided with a flange, which allows the ultrasonic coupling member 300 to be inserted into a corresponding slot of the housing assembly 200 like a drawer, and a seal is formed by a seal on the flange. In this way, the ultrasonic coupling member 300 can also be quickly removed and installed to the housing assembly 200, and the sealing is ensured, so that it can be suitable for sound-conducting media with good fluidity.

[0065] Exemplarily, the coupling film 320 can be made of thermoplastic polyurethane elastomer material, which has strong tensile strength and low processing and production costs. Optionally, the coupling frame 310 can also be connected to the opening by magnetic attraction. For the embodiment in which the coupling agent is applied to the surfaces of both sides of the coupling film 320, due to the high viscosity of the coupling agent, after the ultrasonic probe 100 scans, the detection surface 110 will push all the coupling agent to one side. At this time, magnetic attraction allows the ultrasonic coupling member 300 to be quickly removed, so that the coupling agent can be evenly reapplied. Of course, because the magnetic connection may accidentally fall or leak, it is usually not used with a coupling agent with good fluidity.

[0066] Exemplarily, a filling port 230 connected to the scanning cavity 210 may be provided on the side wall of the housing assembly 200, and the sound-conducting medium may be added to the scanning cavity 210 through the filling port 230. The filling port 230 is in the shape of a longitudinal strip, and the lower end of the filling port 230 extends to be adjacent to the bottom edge of the housing assembly 200. The filling port 230 is sealed by a cover 231, and the cover 231 may be transparent. Before the inspection, the sound-conducting medium may be added from the filling port 230, such as adding water, glycerin or any other suitable coupling agent. When the portable ultrasonic detection device is not in use or needs to be transported (for example, on a flight), the sound-conducting medium in the scanning cavity 210 may be poured out through the filling port 230, thereby reducing the overall weight or meeting the transportation requirements. Pouring out the sound-conducting medium when not in use can also prevent it from deteriorating. After adding the coupling agent, the operator can determine through the transparent cover 231 whether the added sound-conducting medium covers the gap, and whether there is a gap between the detection surface 110 and the ultrasonic coupling element 300 when performing an inner or outer inspection.

[0067] In order to avoid cross infection caused by mixed use by multiple people, or to deal with the aging of the ultrasonic coupling part 300 due to long-term use or improper storage, illustratively, the ultrasonic coupling part 300 is detachably connected to the shell assembly 200. The ultrasonic coupling part 300 can be connected to the shell assembly 200 by any suitable means such as snap fit, interference fit, etc. In this way, there is no need to worry about damage to the ultrasonic probe 100 during the cleaning and disinfection process, and there are no dead corners during cleaning. After a period of continuous use, the operator can disassemble and replace the ultrasonic coupling part 300 with a new one according to the degree of aging of the ultrasonic coupling part 300, without returning to the factory or seeking help from professionals.

[0068] Exemplarily, the ultrasound probe 100 is provided with an indicator mark for aligning the inspection part of the object. The indicator mark can indicate the position of the portable ultrasound detection device to ensure that it can be aligned with the target during the inspection. For example, the indicator mark can be in the shape of a triangle or an arrow, and can be directly opposite the nipple. In the anteroposterior scan, the middle indicator mark can be aligned with the nipple; in the medial scan and the lateral scan, the indicator mark on the left can be aligned with the nipple, and the indicator mark on the right can be aligned with the nipple, respectively, to achieve positioning. In some embodiments, the ultrasound probe 100 can be located near the middle of the scanning cavity before the inspection, so that the indicator mark set thereon can be directly aligned with the nipple, and it is not easy to cause the position to shift due to visual errors. At this time, the ultrasound coupling member 300 can be transparent to facilitate the operator to view. In some embodiments, the shell assembly 200 can also be transparent.

[0069] Exemplarily, the grip assembly 40 may further include a first handle 41 and a second handle 42 respectively disposed on both sides of the housing assembly. Figure 6 As shown, a connection interface 240 may be provided on the rear side of the housing assembly 200, and the connection interface 240 may be electrically connected to the ultrasound host 20. The connection interface 240 is located between the first handle 41 and the second handle 42, and a cable harness 43 is provided on the rear side of the first handle 41 and the second handle 42. For the above-mentioned embodiment in which a power adapter is provided in the housing assembly 200, the connection interface 240 may include a power cord socket or a plug cord connected to the mains. For the embodiment in which a battery is provided inside, or the power adapter connected to the mains is externally provided, the low-voltage electricity output by the power adapter may also be connected to the connection interface 240 of the portable ultrasound detection device through a wire, thereby powering the ultrasound host 20, or charging and using. When examining both breasts, the portable ultrasound detection device has different orientations, and the wires may be fixed through different cable harnesses 43 to ensure that the wires do not fall on the body of the subject during the examination. The cable harness 43 may include a hook, Velcro, etc.

[0070] In an embodiment not shown, the ultrasound probe scans along the transverse direction XX, in other words, scans and moves between the outside and inside of the subject's body. In this case, setting the indicator mark on the ultrasound probe 100 does not provide good guidance. In these embodiments, the indicator mark may also be set on the shell assembly 200 or the ultrasound coupling member 300. The operator estimates that the indicator mark points to the projection of the nipple on the plane of the indicator mark, thereby determining the scanning position. The indicator mark can be set on two mutually perpendicular surfaces of the support device 200, for example, on the front and side of the shell assembly 200. In this way, the projections of the nipple on the two mutually perpendicular surfaces correspond to two indicator marks respectively, which is more convenient for the operator to position.

[0071] Exemplarily, the coupling surface 310 may be a plane, and the ultrasound probe 100 may be a linear array probe. The linear array probe has a higher resolution for superficial structures, and can improve the accuracy of diagnosis for examinations of organs such as breasts. Compared with concave array probes, the linear array probe has a higher yield rate and its cost can be effectively controlled. It is particularly suitable for examinations that do not require high resolution, such as community screening.

[0072] Exemplarily, the portable ultrasonic detection device can also be used for ultrasonic imaging of the liver, and the ultrasonic probe is a convex array probe. Compared with the breast organ, when scanning the liver area, due to the support of the ribs, it is not necessary to apply a lot of pressure, and the ultrasonic coupling member 300 only needs to be attached to the inspection area. The area that needs to be scanned in the liver is much larger than the scanning area required for the breast, and both the transverse direction XX and the longitudinal direction YY have large dimensions (for example, the scanning width may reach 15 cm). In this case, if the length of the ultrasonic probe is made very long, the yield rate of the ultrasonic probe may be seriously reduced, and the cost will be unacceptable. For this reason, a convex array ultrasonic probe can be used, and the ultrasonic beam scanned by it is fan-shaped and can produce a sufficient scanning width at a certain depth. In addition, the convex array ultrasonic probe has a lower frequency and a deeper penetration depth. The ultrasonic probe scans in a direction perpendicular to the scanning width to achieve a sufficient scanning area.

[0073] Another aspect of the present application also provides a portable ultrasonic detection system. Figure 8As shown, the system includes the above-mentioned portable ultrasonic detection device and a base device. The base device may include a receiving tray 400 and a support frame 500, and the support frame 500 has a supporting position for supporting the portable ultrasonic detection device. The receiving tray 400 can be installed to the receiving position below the supporting position, wherein when the portable ultrasonic detection device is located at the supporting position and the receiving tray 400 is in the receiving position, the projection of the ultrasonic coupling member 300 of the portable ultrasonic detection device on the plane where the receiving tray 400 is located completely falls within the projection of the receiving tray 400 on the plane. Optionally, the size of the support frame 500 in the left-right direction may be larger than the size of the portable ultrasonic detection device in the left-right direction, so that the support frame 500 and the portable ultrasonic detection device have a sufficiently large contact surface. Of course, the size of the support frame 500 in the left-right direction may also be less than or equal to the size of the portable ultrasonic detection device in the left-right direction. During the interval between the portable ultrasonic inspection device inspecting two adjacent subjects, or the interval between the inspection of different parts of a subject (such as the medial and lateral parts mentioned above), the operator can place the portable ultrasonic inspection device in a supporting position to prevent the coupling agent on the ultrasonic coupling member 300 from being contaminated, or the coupling agent from contaminating the desktop and other parts. The support frame 500 can make the ultrasonic coupling member 300 suspended in the air, which can also prevent the ultrasonic coupling member 300 from being worn. In the case of a large amount of coupling agent or a relatively thin coupling agent, the coupling agent flowing downward can be collected by the receiving tray 400.

[0074] Exemplarily, the support frame 500 may include a front support 510 and a rear support 520, and a first spacer 600 is provided between at least the upper portions of the front support 510 and the rear support 520, so that the front support 510 and the rear support 520 define a support position from the front side and the rear side, respectively. The portable ultrasonic detection device is located at the support position, the ultrasonic coupling member of the portable ultrasonic detection device is directly above the first spacer 600 or inserted into the first spacer 600, and the receiving tray 400 is located below the first spacer 600.

[0075] As described above, the ultrasonic coupling member 300 of some embodiments includes a coupling frame 310 and a coupling film 320, and the coupling agent is applied to the coupling film 320. When the portable ultrasonic detection device 10 is placed on the base device 20, the coupling frame 310 can be supported on the support frame 500. In this case, the coupling film 320 can be flush with the top surface of the support position. In other embodiments, the ultrasonic coupling member 300 can also be inserted into the first interval 600. As shown in the figure, the support frame 500 can be supported on the housing assembly of the portable ultrasonic detection device 10, and the support positions of the front bracket 510 and the rear bracket 520 are respectively located on both sides of the ultrasonic coupling member 300. In an embodiment not shown, the ultrasonic coupling member 300 can also be inserted into the first interval 600 from the side of the first interval 600.

[0076] In some embodiments, there is an open opening at the top of the first interval 600, and the receiving tray 400 can be put in and taken out from the upper opening, and the ultrasonic coupling member 300 is also accommodated in the upper opening. In the embodiment shown in the figure, the side of the first interval 600 can also be open. During the inspection, the operator may scrape off the excess coupling agent on the subject's body or the ultrasonic coupling member 300 and apply it on the receiving tray 400. Compared with applying from the upper opening, applying from the side is more convenient. Even if the portable ultrasonic detection device has been placed on the support frame 500, the coupling agent can be applied to the receiving tray 400 without picking up the portable ultrasonic detection device. At least one side of the first interval 600 is configured as an open structure, which can also reduce the weight of the base device and make the base device structure simpler and less expensive.

[0077] Exemplarily, the top surface of the rear bracket 520 is recessed downward to form a recessed portion 521, and the recessed portion 521 is used to accommodate the coupling agent container. The portable ultrasonic detection system also includes a heating body arranged in the rear bracket 520, and the heating body is arranged around the recessed portion 521, and is used to heat the coupling agent container. The heating body can adopt an existing or future heating element, such as an infrared heating element, a positive temperature coefficient (PTC) heating body, etc. The heating temperature of the heating body can be constant or adjustable. Optionally, the recessed portion 521 and the outer wall of the container containing the coupling agent can be adapted to achieve a higher heating efficiency. In some embodiments, the recessed portion 521 can be constructed as a plurality of recessed portions spaced from each other to heat multiple bottles of coupling agent at the same time. In some embodiments, multiple bottles of coupling agent can be placed in the recessed portion 521 and heated simultaneously. In short, by providing the recessed portion 521 and the heating body, the coupling agent container can be better positioned and efficiently heated, avoiding the coupling agent temperature being low and causing discomfort to the subject during use.

[0078] Exemplarily, the rear support 520 may be higher than the front support 510. A support protrusion 522 is provided on the front side of the rear support 520, and the support protrusion 522 together with the top of the front support 510 defines the support position. Since the fluidity of the coupling agent is generally poor, if only a portion of the coupling agent container is heated, it may cause a portion of the coupling agent to have a higher temperature and another portion of the coupling agent to have a lower temperature, resulting in a poor experience for the subject. The coupling agent container is generally a standard part, and therefore, the higher rear support 520 may form a sufficiently deep recess 521, and the heating body may cover the inner side wall of the entire recess 521, thereby heating the coupling agent in the entire coupling agent container. The vertically arranged recess 521 can be suitable for any viscous coupling agent, and even if a relatively thin coupling agent is used, the coupling agent will not spill. The front support 510 does not need to be set to the same height as the rear support 520, and when the operator places the portable ultrasonic detection device on the support frame 500, it can first be placed against the higher surface of the rear support 520 and then aligned downward, thereby playing a guiding role and preventing the coupling agent from being contaminated on the surface of the support frame 500 during the alignment process.

[0079] Exemplarily, the receiving tray 400 is detachable relative to the support frame 500. This makes it easier to clean the receiving tray 400. In some embodiments, the receiving tray 400 can be placed only at the first interval 600 without being connected to the support frame 500. In some embodiments, the receiving tray 400 can be connected to the support frame 500 through structures such as magnetic attraction and guide grooves. Preferably, the support frame 500 can limit the horizontal position of the receiving tray 400 so that it is positioned within the first interval 600. On this basis, Fig.10 As shown, the bottom of the front bracket 510 is telescopically connected to the bottom of the rear bracket 520. Wherein: when the front bracket 510 is in the extended position, a first interval 600 is formed between the front bracket 510 and the rear bracket 520; when the front bracket 510 is in the retracted position, a second interval is formed between the front bracket 510 and the rear bracket 520, and the receiving tray 400 removed from the receiving position can be accommodated in the second interval. The width of the receiving tray 400 is close to the first interval 600 and is greater than the height of the receiving tray 400. After the receiving tray 400 is removed, the interval between the front bracket 510 and the rear bracket 520 is reduced to the second interval, so that the volume of the base device is reduced, which is convenient for carrying the portable ultrasonic detection system. The receiving tray 400 can be inserted into the second interval upright, thereby improving the space utilization rate during storage.

[0080] Exemplarily, the left and right sides of the bottom of the rear bracket 520 have a pair of first telescopic parts 523 protruding forward, and the left and right sides of the bottom of the front bracket 510 have a pair of second telescopic parts 511 protruding backward. The pair of second telescopic parts 511 are telescopically connected to the pair of first telescopic parts 523. When the receiving tray 400 is in the receiving position, the receiving tray 400 is located between the pair of first telescopic parts 523 and between the pair of second telescopic parts 511. The pair of first telescopic parts 523 and / or the pair of second telescopic parts 511 are used to limit the receiving tray 400 in the receiving position along the left and right directions. Figure 7 , a portion of the second telescopic portion 511 is smaller than the first telescopic portion 523, so that it can be inserted into the first telescopic portion 523. Such a telescopic structure is relatively simple and reliable. In other embodiments, the first telescopic portion 523 can also be inserted into the second telescopic portion 511, or a portion of each of them is inserted into the other telescopic portion. When the receiving tray 400 is in the receiving position, the edge of the receiving tray 400 can abut against the opposite surfaces of a pair of first telescopic portions 523 and a pair of second telescopic portions 511, or a pair of first telescopic portions 523 and a pair of second telescopic portions 511 only block the movement of the edge of the receiving tray 400 in the left and right directions, and are not tightly fitted to the edge of the receiving tray 400.

[0081] Exemplarily, the front bracket 510 also has a U-shaped door frame with an opening facing downward. A pair of second telescopic parts 511 are respectively connected to the U-shaped door frame, and the receiving tray 400 is detachably mounted to the receiving position via the opening of the U-shaped door frame. The top of the U-shaped door frame is used to define the support position. In some embodiments, the U-shaped door frame may include a crossbeam 512, and a portion of the surface of the portable ultrasonic device may be supported on the upper surface of the crossbeam 512. In the embodiment shown in the figure, the upper surface of the crossbeam 512 may be provided with an extension in the direction of the support protrusion 522, and the upper surface is flush with the upper surface of the support protrusion 522, thereby defining the support position. The U-shaped door frame can save materials and reduce the weight of the base device. The receiving tray 400 can be pulled out or inserted from the bottom opening of the U-shaped door frame, and the operation is more convenient. When applying excess coupling members to the receiving tray 400, applying through the opening of the U-shaped door frame is not easy to contaminate the coupling agent on the support frame 500, and the operation is simpler and easier to clean. Optionally, the operator may also pull the receiving tray 400 out of the opening below the U-shaped door frame and then apply excess coupling members to the receiving tray 400 .

[0082] For example, a handle that is recessed inwards may be provided on the back of the base device. The handle may be substantially the same height as the front bracket, and the operator may hold the crossbeam 512 of the front bracket 510 and the handle and pull in two directions to unfold the base device from the stored state. This makes it easier for the operator to exert force and prevents slippage when pulling.

[0083] For example, along the left-right direction, the base device is approximately the same size as the portable ultrasonic detection device. Along the height direction, the base device is approximately the same size as the portable ultrasonic detection device. Fig.11 As shown, the size difference can be understood as no more than 5 cm. When the portable ultrasonic detection system is in the storage state, the front bracket 510 is in the retracted position and the receiving tray is accommodated in the second compartment, and the portable ultrasonic detection device and the base device are arranged along the front-to-back direction. Thus, the portable ultrasonic detection system can be accommodated in a container with a relatively regular shape, and there will be no corners that are prone to collision during transportation, making it more convenient to carry.

[0084] Exemplarily, when the portable ultrasonic detection system is in the storage state, the total length of the base device and the portable ultrasonic detection device in the front-to-back direction is not more than 520 mm, the total width in the left-to-right direction is not more than 400 mm, and the height of both is not more than 200 mm. This allows the portable ultrasonic detection system to be placed in a smaller suitcase after storage, and can follow the personnel on board or take other means of transportation. As shown in the figure, the support frame 500 of the base device and the portable ultrasonic detection device can be placed side by side, and the receiving tray 400 can be placed in the gap between the front bracket 510 and the rear bracket 520 of the base device. Not shown, filling material can also be provided in the suitcase to prevent the base device and the portable ultrasonic detection device from colliding with each other or colliding with the inner wall of the suitcase during transportation and being damaged.
