According to a first embodiment of the present invention, there is provided a vibration transmitting device for detecting surface vibrations of muscle tissue:
a vibration transmission device for detecting surface vibrations of muscle tissue, the vibration transmission device comprising: a central vibration transmission part 1; a noise reduction part 2 covering the outside of the central vibration transmission part 1; the mounting part 3 is covered on the outer side of the noise reduction part 2, and the mounting part 3 is used for being connected with an external structure; the central vibration transmission part 1, the noise reduction part 2 and the mounting part 3 are positioned on the same horizontal plane.
The application provides a technical scheme of a vibration transmission device for detecting the surface vibration of muscle tissues. In the technical scheme, the whole vibration transmission device is connected with an external mechanism through a mounting part; the mounting portion is connected with an external mechanism, and the central vibration transmission portion is connected with the mounting portion through the noise reduction portion, so that the mounting state of the mounting portion cannot be directly transmitted to the central vibration transmission portion. One side of the central vibration transmitting portion is in contact with an external vibration source and transmits vibration to one side of the central vibration transmitting portion. In the process of transmission, because the installation part and the central vibration transmission part are not in direct connection, the vibration signal transmitted by the central vibration transmission part is basically not influenced by the post-installation state of the connection between the installation part and the outside. The technical scheme that this application provided can effectual improvement vibration signal transmission's quality, reduces the influence to vibration transmission under different installation condition or the state.
In the prior art, the acoustic signal inside the biological tissue is generally detected by closely attaching a thin film to the surface of the biological tissue. That is, when the membrane vibrates, sound is generated in a space adjacent to the membrane and is transmitted to the listening area through the duct. Because the film is installed, whole relatively gentle, if the part installation too tight or make the film produce deformation with the laminating of external mechanism, all can influence the vibration signal that the film transmitted.
In the prior art, there is also a korotkoff sound monitoring device that identifies the vibration signal by monitoring the position of the point of reflection of the directed light on the vibration source. In the prior art, however, the vibration conduction is only carried out through a common flexible film; since the flexible film is susceptible to the effects of its mounting state (creases, pre-stress, deformation), errors occur in the vibrations that are ultimately transmitted. For another example, if the film is tensioned, the film itself is not easily vibrated, i.e., the amplitude is reduced; if the film is loose, the recovery speed of the film is insufficient, namely the film cannot sensitively monitor the high-frequency vibration.
The external vibration source is epidermal vibration of a biological tissue.
Specifically, in the embodiment of the present invention, the noise reduction part 2 is a flexible noise reduction part.
Specifically, in the embodiment of the present invention, the noise reduction part 2 is a noise reduction part made of an elastic material.

It should be noted that the fine tuning fluid disposed in the fine tuning cavity may not be a fixed relationship between the collision structure and the vibrating body, that is, in a specific implementation situation, since the surface of the biological tissue contacted by the collision structure is not necessarily a flat surface, the biological tissue may have an additional force on the collision structure, so that the collision structure may deviate to some extent. Through the characteristics of the fine tuning cavity, the fine tuning fluid and the flexible or elastic connection of the collision structure and the vibrated main body, the influence of the deviation of the collision structure on the vibrated main body is reduced, and the vibration signal can be transmitted to the maximum extent by the vibrated main body.

It should be noted that the clamping band can facilitate the fixing of the mounting portion to the external structure.
