[0032] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides an ultrasonic scanning device, comprising at least: a water injection system 1; a breast cup 2, wherein the inner bottom wall of the breast cup 2 is provided with a water inlet groove 201, the water inlet groove 201 being recessed relative to the inner bottom wall of the breast cup 2; a water inlet pipe 202 being provided at the inlet of the water inlet groove 201, the inlet end of the water inlet pipe 202 being connected to the outlet of the water injection system 1; a first groove wall 2011 of the water inlet groove 201 adapted to fit the outlet end of the water inlet pipe 202, being a curved surface, and the outlet end of the water inlet pipe 202 being arranged tangent to the first groove wall 2011. For example, the first groove wall 2011 may be a spherical surface, an arc surface, or other smooth curved surface.

[0037] The ultrasonic scanning device provided in this embodiment has a water inlet groove 201 provided on the inner bottom wall of the cup 2. The water inlet groove 201 is recessed relative to the inner bottom wall of the cup 2. A water inlet pipe 202 is provided at the inlet of the water inlet groove 201. A first groove wall 2011 of the water inlet groove 201 adapted to the outlet end of the water inlet pipe 202 is a curved surface. The outlet end of the water inlet pipe 202 is arranged tangent to the first groove wall 2011. When liquid enters the water inlet groove 201, because the outlet end of the water inlet pipe 202 is tangent to the first groove wall 2011, the liquid can flow along the first groove wall 2011, reducing turbulence and thus reducing the interference of bubbles introduced by mixing with air on ultrasonic imaging. Moreover, when the liquid overflows from the water inlet groove 201 into the cup 2, the liquid level in the cup 2 slowly rises, the water flow is smooth, and no bubbles are introduced.

[0038] like Figure 4 As shown, the water inlet groove 201 is a waist-shaped structure without right-angle turns. For example, the first groove wall 2011 is a convex groove wall of the waist-shaped structure. This configuration allows liquid to swirl and fill the water inlet groove 201. After the liquid has completely submerged the inlet of the water inlet groove 201, it enters the cup 2 without introducing air. The liquid does not mix or agitate with the air in the cup 2, and the entire cup 2 is slowly filled, which is beneficial for improving the bubble suppression effect.

[0039] like Figure 1 、 Figure 7 、 Figure 8As shown, the water injection system 1 includes a water tank 101, a first pump body 102, a first control valve 103, a second control valve 104, a third control valve 105, and a fourth control valve 106; the first control valve 103 and the second control valve 104 are both three-way valves; the first interface of the first control valve 103 is connected to the outlet of the first pump body 102, and the first interface of the second control valve 104 is connected to the inlet of the first pump body 102; the second interface of the first control valve 103 and the inlet of the third control valve 105 are both connected to the inlet of the fourth control valve 106; the third interface of the first control valve 103 and the second interface of the second control valve 104 are evenly connected to the first water inlet of the water tank 101; the third interface of the second control valve 104 is connected to the outlet of the third control valve 105; and the outlet of the fourth control valve 106 is connected to the inlet end of the water inlet pipe 202. The three-way valve can be switched between normally closed and normally open, so that the three interfaces can realize two different paths. When water needs to be added to the breast cup 2, the first control valve 103, the second control valve 104, and the fourth control valve 106 are powered on, the first and second interfaces of the first control valve 103 are connected, the first and second interfaces of the second control valve 104 are connected, and the fourth control valve 106 is connected. The first pump body 102 can pump water from the water tank 101 and output it to the breast cup 2 through the fourth control valve 106. When the water in the breast cup 2 needs to be withdrawn, the first control valve 103 and the second control valve 104 are de-energized. At this time, the first and third interfaces of the first control valve 103 and the first and third interfaces of the second control valve 104 are connected, and the third and fourth control valves 105 and 106 are powered on. The first pump body 102 can pump the water in the breast cup 2 back to the water tank 101.

[0040] The water injection system 1 also includes a filter 107, located in the pipeline between the second port of the first control valve 103 and the inlet of the fourth control valve 106. For example, the filter 107 contains PP cotton, activated carbon, and an RO reverse osmosis membrane. The PP cotton and activated carbon filter and absorb impurities from the recycled sound-conducting medium; the RO reverse osmosis membrane further filters impurities, salt compounds, and other substances from the sound-conducting medium, effectively improving the purity of the water injection medium. Furthermore, the filter 107 can also filter out some microbubbles, thereby suppressing bubbles.

[0041] The water injection system 1 further includes a heater 109 and a second pump body 108; the inlet of the second pump body 108 is connected to the second water inlet of the water tank 101, and the outlet of the second pump body 108 is connected to the third water inlet of the water tank 101; the heater 109 is disposed in the pipeline between the outlet of the second pump body 108 and the third water inlet of the water tank 101. The direction of the second pump body 108 remains unchanged, pumping water from the water tank 101, which then flows back to the water tank 101 after passing through the heater 109. The temperature of the heater 109 can be set to maintain a constant temperature in the water tank 101 through this cyclic heating method. For example, the heating temperature of the heater 109 can be set to a temperature close to human body temperature, which facilitates the release of bubbles and improves patient comfort. With this arrangement, the cooperation of the first pump body 102, the second pump body 108 and the heater 109 can circulate and heat the low-viscosity ultrasonic medium in the water tank 101, thereby maintaining a constant temperature and facilitating access. At the same time, it can reduce bubbles dissolved in the liquid, thereby preventing bubble precipitation during the process of being transported to the cup 2 and interfering with ultrasonic imaging.

[0042] like Figure 9 As shown, the third control valve 105 is a three-way valve; the first port of the third control valve 105 is connected to the inlet of the fourth control valve 106; the second port of the third control valve 105 is connected to the third port of the second control valve 104; and the third port of the third control valve 105 is connected to the fourth water inlet of the water tank 101. For example, when the first control valve 103 and the second control valve 104 are powered on, and the third control valve 105 and the fourth control valve 106 are powered off, the first port of the third control valve 105 is connected to the third port, and the fourth control valve 106 is disconnected. The first pump body 102 can circulate the warm water in the water tank 101 between the pipeline and the filter 107, ensuring that warm water is output.

[0043] like Figure 5 、 Figure 6 As shown, the breast pad 3 is also included. The breast pad 3 is an annular structure. For example, the breast pad 3 can be made of non-woven fabric with a certain thickness and cushioning properties. The breast pad 3 is arranged along the circumferential direction of the cup 2 at the open edge of the top of the cup 2 to fill the gap between the cup 2 and the chest wall when the breast 4 is compressed, thereby reducing the strong reflection of sound waves at the interface between water and the chest wall. For example, the breast pad 3 can be a disposable consumable. For example, the breast pad 3 can be connected to the cup 2 using double-sided adhesive tape to facilitate replacement.

[0044] When water is injected into the cup 2 via the water injection system 1, the amount of water injected should completely submerge the breast 4 submerged within the cup 2, leaving no air layer between the chest wall surrounding the breast 4 and the water surface. For example, before use, the system can automatically or manually adjust the amount of water injected into the cup 2 to appropriately increase the area covered by the sound-conducting liquid, avoid the appearance of a "cavity" between the water surface and the skin, and significantly reduce the risk of artifacts. For example, if a reflection of an air layer can be seen through the camera, water should be injected until the reflection disappears, confirming that there is no air layer between the chest wall surrounding the breast 4 and the water surface.

[0045] The inlet of the water inlet tank 201 also serves as its outlet. Because the cup 2 rotates, separate inlet and outlet configurations would require two water pipes, creating excessive rotational resistance, unstable rotation, and the risk of entanglement. Therefore, the fewer water pipes, the better. This configuration allows the cup 2 to inject and withdraw low-viscosity ultrasonic media even with only one inlet and outlet, allowing it to circulate throughout the system.

[0046] The ultrasonic sound-conducting medium stored in the water tank 101 in the present application may be water or other low-viscosity liquids.

[0047] Among them, the ultrasonic scanning equipment in this application also has a scanning system, an imaging system, etc., which are existing technologies that can be known to those skilled in the art and will not be described in detail here.

[0048] During use, the body part to be scanned is placed in the cup 2, and the system extracts the low-viscosity sound-conducting medium from the water tank 101 and injects it into the cup 2, immersing the body part to be scanned. The ultrasonic probe can image the body part by scanning the medium.

[0049] In summary, the ultrasonic scanning equipment provided by this application improves image quality, significantly reduces imaging distortion and signal obstruction caused by water bubbles and mirror artifacts, and improves image clarity and edge stability.

[0050] The ultrasonic scanning equipment provided in this application has enhanced system stability and multiple bubble removal and water flow slow-release mechanisms to ensure the long-term stability and uniformity of the sound-conducting medium and reduce the frequency of equipment maintenance.

[0051] The ultrasound scanning device provided in this application has strong adaptability and is suitable for different breast sizes and different device structures. The water injection speed, temperature, and pressure are adjustable, and it has good compatibility.

[0052] The ultrasound scanning equipment provided in this application is clinically friendly to operate. The system automatically controls the water flow path and medium processing, eliminating the need for frequent intervention by medical staff, thereby improving clinical efficiency and control experience.

[0053] The ultrasonic scanning equipment provided in this application is low-cost, and its structural design is mainly based on physical optimization, supplemented by a simple filter element and a low-cost cushion layer. It does not require expensive consumables and complex electronic control, and has a high cost-effectiveness.

[0054] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
