Embodiment 1

[0035] like figure 1 As shown, the soft attachment and fixing device for ultrasonic scanning disclosed by the present invention has good sound permeability and elasticity, including the attachment and fixing device body 1, and the inner surface of the attachment and fixing device body 1 is suitable for the surface shape of the bonding part. Matching, attaching the outer surface of the fixing device body 1 is smooth, so that the ultrasonic probe can move smoothly on the irregular surface, improve the movement accuracy of the probe, form the smallest image transition difference, and minimize the image interpolation in image reconstruction; The surface of the device body 1 is attached with infrared or laser reflective material, the reflection coefficient of the infrared or laser reflective material is above 0.7, and the infrared or laser reflective material does not fully cover the front of the attached fixing device body 1 .

[0036] Among them, the material of the attaching and...

Embodiment 2

[0040] Ultrasound is a mechanical wave, produced by the mechanical vibration of an object. The ultrasonic frequency used in medicine is 2.5-10MHz, and the commonly used one is 2.5-5MHz. Ultrasound needs to propagate in the medium, and its speed varies with different media, the fastest in solid, the second in liquid, and the slowest in gas. It is about 150m / s in human soft tissue. The medium has a certain acoustic impedance, which is equal to the product of the density of the medium and the ultrasonic velocity.

[0041] Ultrasound propagates in a straight line in the medium and has good directivity. This is the basis for detecting human organs with ultrasound. When ultrasound passes through the interface of two adjacent media with different acoustic impedances, the difference in acoustic impedance is greater than 0.1%, and the interface is significantly larger than the wavelength, that is, when the interface is large, reflection occurs. The greater the difference in acoustic ...

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that the fixing belt is replaced by a clamping device, which includes a single-sided adhesive plaster 41, a matching clamping joint 42 and a bayonet 43; the bayonet 43 is located on the body 1 of the attachment fixing device On the inner surface, the clamp joint 42 is located on the non-adhesive surface of the single-sided adhesive plaster 41, and there are at least two clamp joints 42 and bayonet sockets 43 respectively.

Abstract

The invention relates to a soft attachment fixing device with good sound transmission and elasticity and for ultrasonic scanning. The device comprises an attachment fixing device body, the inner surface of the attachment fixing device body is matched with the surface of an attachment part in shape, and the outer surface of the attachment fixing device body is smooth or in a grid shape. Matter capable of reflecting infrared light or laser is attached to the surface of the attachment fixing device body. By means of the device, moving precision of a probe is improved, superficial organs are fixed, minimum image transition difference is formed, gas between the attachment fixing device body and the body surface is reduced to the largest extent, and image interpolation in image reconstruction is reduced to the largest extent. Meanwhile, stability and standardization of organic shape are guaranteed during ultrasonic scanning of easily-deformed organs; customized adaptation design in different shapes is conducted on different portions of a human body, the device is attached to the surface of the irregular human body or the organs to the largest extent, regular, smooth and continuous basic image sources are obtained on the irregular surfaces, image quality is improved, and the device can be used for automatic ultrasonic scanning.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a soft attachment and fixing device with good sound permeability and elasticity for ultrasonic scanning. Background technique [0002] 1. Ultrasonic examination (US examination) is to use the human body to observe the reflection of ultrasonic waves. Ultrasound examination, generally called US, is to irradiate the body with weak ultrasonic waves, and image the reflected waves (echo) of the tissues. [0003] 2. Ultrasonic imaging is to use ultrasonic beams to scan the human body, and obtain images of internal organs by receiving and processing reflected signals. There are many kinds of ultrasonic instruments commonly used: Type A (amplitude modulation type) indicates the strength of the reflected signal by the height of the amplitude, and what is displayed is a kind of "echogram". M type (spot scanning type) represents the spatial position from shallow to deep in the vertical d...
