Problems solved by technology

However, the instrument is still cumbersome to operate, time-consuming and has poor patient experience, and cannot obtain a complete full-breast image at one time
[0007] Logically, it is possible to use a silicone sheet or mesh with good sound permeability as a material for attaching and fixing the breast, but the silicone sheet is prone to air gaps and wrinkles, which will cause artifacts in ultrasound imaging
Silicone mesh is easy to form a large number of sound shadows due to the rotation, folding and clustering of the mesh cables, resulting in unclear ultrasound images
[0008] In addition, the patent document (CN 105596029 A) discloses a "soft attachment and fixing device with good sound permeability and elasticity for ultrasonic scanning", which uses a silica gel mesh structure, but it is difficult to make the silica gel fine and not Fractured mesh, which causes the silicone strips to form acoustic shadows on ultrasound imaging and reduce imaging quality

preparation example Construction

[0054] The preparation method of the standardized fixed bionic sound-permeable membrane adopts silk, polyvinyl acetal fiber, polyester cotton, combed cotton, mercerized cotton, polyurethane fiber, 3D polyurethane fiber, polyamide fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl chloride fiber, polyester fiber, polyolefin elastic fiber, cotton polyester blend, acrylic blend, fine wool blend, polyurethane fiber, velvet, polyester resin, ultra-thin One or more blends of type velvet, Lilion fiber, MODAL modal fiber, polyester amine fiber and polyamide fiber silk form elastic fiber bionic microporous sound-permeable membrane, and elastic fiber bionic microporous sound-permeable membrane A bionic sound-permeable membrane for standardized breast ultrasound scans was fabricated.

[0055] Further, carrying out the blending dense weaving process according to any one or one or more fibers in the above-mentioned elastic fiber materials may include the following steps:

Embodiment 1

[0063] Embodiment 1: the preparation method of elastic fiber membrane of the present invention

[0064] The elastic fiber membrane is made of any elastic fiber densely woven, and the Lycra nylon wrapping yarn used is wrapped with Lycra spandex yarn, so that the fixed bionic sound-permeable membrane has both the elasticity of spandex and the smoothness and smoothness of nylon yarn. Transparent and delicate. In order to improve the elasticity and comfort of the device, the material of the straight wire is Lycra. Lycra Choose one of the following Lycra filaments: A7, A13, 7.7dTex136C Lycra, 11dTex156C Lycra, 14.3dTex136C Lycra, 16.5dTex156C Lycra and 22dTex146C Lycra.

[0065] The MATEC loom with 7mm needle latch is used, and the speed is set at 600-800r / min. Use one or three lines and two lines to enter the line, and increase the pressure needle triangle. After the conventional elastic fiber weaving process: twisting raw materials→dyeing→winding→weaving wire mesh→inspection→s...

Embodiment 2

[0076] Embodiment 2: Standardized wearing method of the bionic sound-permeable membrane of the present invention

[0077] Choose a female volunteer with large breasts on both sides. The size of the breast shield is G cup. Due to the large breast volume, the probe pushes and shifts the breasts during routine ultrasound examination. It is difficult to ensure a complete and comprehensive breast scan for this large breast patient It is difficult to accurately locate the lesion when checking at different times. In order to ensure that the breast position of the examiner can be in the same position and complete a comprehensive scan at different times, a standardized fixed bionic sound-transmitting membrane is worn for the female volunteer before the examination. time, such as Figure 6 As shown in (B), first of all, fasten the buckle from the back side to achieve preliminary fixation; in order to achieve accurate left-right symmetry, as shown in Figure 6 As shown in (A), the assi...

Abstract

The invention relates to a bionic acoustic transmission membrane for realizing mammary gland ultrasonic standard scanning and a preparation method thereof. The bionic acoustic transmission membrane comprises a wearable attaching and fixing accessory which comprises an elastic fiber membrane, and the elastic fiber membrane is formed by blending and weaving one or multiple of polyester resin, real silk, polyvinyl acetal, polyester cotton, combed cotton, mercerized cotton, polyurethane fiber, 3D polyurethane fiber, polyamide fiber, polyamide fiber, polyacrylonitrile fiber, polyvinyl chloride fiber, polyester fiber and polyolefin elastic fiber. A standard flexible frame for mammary gland scanning examination is built by mainly using the elastic fiber microporous acoustic transmission membrane,the bionic acoustic transmission membrane has excellent acoustic transmissivity, does not form an acoustic shadow like a silica gel stripe during ultrasonic scanning and enables mammary gland to be free of obvious displacement to form smooth ultrasonic image transition for reducing image interpolation in image reconstruction to greatest extent and improve imaging quality during three-dimensionalreconstruction.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bionic sound-permeable membrane with excellent sound permeability and elasticity and full of fine pores, which is used for standardizing breast ultrasound scanning images and positions, and a preparation method thereof. Background technique [0002] Ultrasonic diagnosis has become the main means of clinical diagnosis because of its non-invasive, safe and rapid characteristics. Among them, breast ultrasonography has become a routine breast tumor screening technique, which is widely accepted and recognized in clinic. However, the accuracy of breast ultrasound diagnosis and the completeness and standardization of breast scan are restricted by the following factors: [0003] High mobility: The mammary gland is a superficial organ with high mobility, especially for women after breastfeeding. Due to the increase in fat content, atrophy or excessive hyperplasia of the gland, ...
