Description

Technical Field

[0001] The present invention belongs to the technical field of ultrasound equipment, and specifically discloses a breast acoustic coupling wearable device for early screening of ultrasonic breast cancer. Background Art

[0002] Breast cancer is the most common malignant tumor in women worldwide. The 5-year survival rate for early detection (stage I) exceeds 95%, while that for late stage (stage IV) is less than 30%, highlighting the value of early screening. From the popularization of mammography in the 1960s to the addition of breast ultrasound / MRI after 2000 to the implementation of AI-assisted diagnosis in the 2020s, early screening for breast cancer has undergone a period of development. The current core means of early screening is to focus on screening people over 40 years old, using "mammography (mammography) combined with ultrasound" as the gold standard (Guidelines of the China Anti-Cancer Association). Driven by policies, China's upgraded "Breast Cancer Screening Work Plan" in 2022 mentioned that the core target population for early screening of breast cancer is high-risk women aged 45-70; the screening path is planned as initial screening with questionnaires → fine screening with imaging → pathological confirmation.

[0003] The breast ultrasound examination mentioned here is the most important means of early screening for breast cancer. During the entire early screening process, a qualified ultrasound physician is required to operate the ultrasound equipment and diagnose the ultrasound image results. It takes an average of 40 minutes to diagnose a case, including 20 minutes for collecting breast ultrasound images and 20 minutes for medical diagnosis of breast ultrasound images, a total of 40 minutes (average data).

[0004] Traditional volumetric ultrasound probes require repeated scanning and partitioned scanning when scanning one breast at a time. The adaptability of traditional volumetric ultrasound probes to breasts of different sizes and shapes in different patients solves the problem of insufficient contact between the device and the skin and the presence of air gaps when traditional volumetric ultrasound probes come into contact with different patients' breasts.

[0005] Therefore, there is an urgent need to propose an easy-to-use breast ultrasound-coupled wearable device for early screening of breast cancer. Summary of the Invention

[0006] In response to the above problems, the present invention discloses a breast acoustic coupling wearable device for early screening of breast cancer by ultrasound.

[0007] The purpose of the present invention is achieved through the following technical solutions.

[0008] A breast acoustically transparent coupled wearable device for early screening of breast cancer through ultrasound comprises an early screening device probe positioning strip, a scanning surface, a strap, a body-fitting surface, a constant temperature fluid filler connection port, and two breast fitting positions supported by the scanning surface and formed in cooperation with the body-fitting surface, wherein the strap is used to fix the device on the human body; the body-fitting surface adopts a soft and ductile ultrasonic acoustically transparent film that fits the human torso, and the strap is connected to the body-fitting surface; a scanning surface is provided on the outside of the body-fitting surface; a scanning surface is provided on the outside of the body-fitting surface, and an early screening device probe positioning strip for locating the position of the early screening device probe is provided on the scanning surface; a breast fitting position is provided on the inside of the fitting surface, and the breast fitting position is provided with a breast fitting cavity, and the breast fitting cavity is provided with a gap and connected to the constant temperature fluid filler.

[0009] Furthermore, the scanning surface adopts a hard ultrasonic sound-transmitting film.

[0010] Furthermore, the scanning surface matches the contour of the early screening device probe.

[0011] Furthermore, a pressure sensor is provided inside the breast fitting position.

[0012] Furthermore, a liquid filler connection port is provided on the scanning surface.

[0013] Furthermore, the gap of the breast adaptation cavity is formed by the cooperation of the scanning surface and the body-fitting surface.

[0014] The present invention discloses a glandular acoustic image self-collection auxiliary diagnosis system, which uses the breast acoustic coupling wearable device for ultrasonic breast cancer early screening, including a folding bed for carrying the screening object and positioning, an early screening probe is arranged above the folding bed, the early screening probe is connected to the early screening server, and the early screening server transmits the ultrasound image to the diagnosis service station.

[0015] Compared with the existing technology, the present invention has the following advantages and beneficial effects:

[0016] The constant temperature liquid filler in the breast acoustically transparent coupling wearable device provided by the present invention, combined with the breast adaptation cavity and the breast adaptation position deformation, can adapt to breasts of various shapes and sizes of different patients. Combined with the ultrasonic coupling agent in the breast adaptation cavity, it realizes lossless transmission of ultrasonic scanning images.

[0017] The scanning surface of the breast acoustically coupled wearable device provided by the present invention is a fixed shape that matches the external contour of the early screening probe, simplifying the scanning process. It is only necessary to place the probe in a specified position and wait for the ultrasonic array in the probe to actuate once to complete unilateral breast ultrasound scanning and imaging.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is described in further detail below. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the present invention.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the embodiments.

[0026] Combine Figure 1-3 The present invention provides a breast acoustic coupling wearable device for early screening of ultrasonic breast cancer, including a strap 1, an early screening probe positioning strip 4, a scanning surface 3, a body-fitting surface 2, a constant temperature liquid filler connection port 8, and two breast adaptation positions 5 formed by the scanning surface as a support and cooperating with the body-fitting surface.

[0027] Specifically, the strap 1 is the same as an ordinary bra strap. The strap 1 is connected to the body-contacting surface 2 that contacts the human body. The body-contacting surface 2 is made of a soft and ductile ultrasound-transparent film that adapts to different patients through its deformation, such as silicone material. A scanning surface 3 for ultrasound scanning is provided on the outside of the body-contacting surface 2. The scanning surface 3 is composed of a hard ultrasound-transparent film that is not easily deformed. The uniform shape is convenient for unifying the size of the early screening probe, such as a polymer-based hard sound-transparent material (PMMA). An early screening probe positioning strip 4 is provided in the center of the scanning surface 3 to locate the position of the early screening probe.

[0028] The ultrasound process requires an ultrasonic coupling agent. A gap exists where the soft film of the body-fitting surface 2 overlaps with the hard film of the scanning surface 3, allowing for the airless injection of a certain amount of ultrasonic coupling agent during the ultrasound process. This area is then shaped to form two breast-fitting areas 5. Furthermore, the gap where the soft film of the body-fitting surface 2 overlaps with the hard film of the scanning surface 3, combined with the shaped breast-fitting areas, forms a breast-fitting cavity 6. This cavity 6 is connected to a fluid filler connection port 8 on the scanning surface, through which a constant-temperature fluid filler 9 injects ultrasonic coupling agent.

[0029] As an embodiment of the present invention, refer to Figure 2-3 In order to ensure the accuracy of the judgment structure for whether the fitting is complete, a number of pressure sensors 7 are further provided on the inner side of the breast fitting position 5.

[0030] Another embodiment of the present invention also provides a glandular acoustic image self-acquisition auxiliary diagnosis system, which includes a portable folding bed 10, an early screening instrument server, an early screening instrument probe 12, a breast acoustic coupling wearable device, a liquid-filled nipple patch, a constant temperature liquid filler 9 and a diagnostic service station 11.

[0031] Among them, the portable folding bed 10 is used to carry the screening object and position it. The early screening instrument probe 12 is different from the ordinary ultrasound probe. Its width is wider and is used to cover the entire breast projection width, so as to realize a single scan of the entire left breast or right breast. The early screening instrument server is used to control the early screening instrument probe to move downward and position and fit the liquid-filled nipple to perform ultrasound imaging scanning, and collect ultrasound images and transfer them to the diagnosis service station. The breast acoustic coupling wearable device is used to fit the breast tightly to achieve the milk pressure function. Its filling function is used to adapt to different breast shapes and sizes to unify the scanning surface of the early screening instrument probe. The constant temperature liquid filler 9 adjusts the size of the stretch membrane on the wearing side of the breast acoustic coupling wearable device by heating and injecting liquid to adapt to different breast sizes and shapes of different patients, while avoiding the discomfort of low instrument temperature during ultrasound screening. The diagnosis service station 11 uses the obtained breast ultrasound image for auxiliary diagnosis and stores the results.

[0032] When using the present invention, refer to Figure 4-5 , including the following steps:

[0033] 1. Preparation before the examination

[0034] Clothing adjustments: Wear loose-fitting tops (to expose the chest) and remove jewelry or clothing accessories in the breast area.

[0035] Skin cleaning: Avoid applying skin care products or cosmetics on the breasts to prevent the coupling agent from coming into contact with the skin and affecting imaging.

[0036] Time selection: It is recommended to check during the non-menstrual period (preferably 7-10 days after menstruation, when the breast tissue is softer).

[0037] 2. Wear a breast-transmitting acoustic coupling wearable device

[0038] The patient wears the breast acoustic coupling wearable device, which is worn like a regular bra. (1 minute)

[0039] 3. Body Positioning

[0040] The patient lies flat on the designated position on the portable folding bed. Align the upper edge of the wearable breast acoustic coupling device with the indicator mark. Connect the constant temperature fluid inflator. Raise both arms to hold the head, fully exposing the wearable breast acoustic coupling device. (1 minute)

[0041] 4. Breast acoustic coupling wearable device adapts to breast contours

[0042] The constant temperature liquid filler heats the liquid for injection or aspiration (the liquid is the ultrasound coupling agent) to make the breast acoustic coupling wearable device fit tightly to the breast. (1 minute)

[0043] 5. Early screening device probe scans downward

[0044] The early screening device probe lowers to the scanning surface of the breast acoustic coupling wearable device and performs an ultrasound imaging scan, once for each breast, for a total of two scans from bottom to top. The early screening device server generates a breast ultrasound image and transmits it to the diagnostic service station. (4 minutes, 2 minutes for a single breast scan)

[0045] 6. Image-assisted diagnosis

[0046] The diagnostic service station diagnoses the transmitted breast ultrasound images based on the early screening model and provides auxiliary diagnosis results. (3 minutes)

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the present invention specification, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
