Ultrasonic probe for measuring subcutaneous tissue thickness and measuring instrument

Abstract

The invention relates to the fields of medical equipment technology and health electronic products, and in particular provides an ultrasonic probe and a measuring instrument for measuring the thickness of subcutaneous tissue. The ultrasonic probe comprises: a separate transmitting chip and a receiving chip; a transmitting side backing layer arranged on the back side of the transmitting chip; a receiving side backing layer arranged on the back side of the receiving chip; and a partition made of insulating and Sound-absorbing material preparation, including: a first isolation section, sandwiched between the emitting wafer and the receiving wafer; and a second isolation section, sandwiched between the emitting side backing layer and the receiving side backing layer . The invention completely separates the lining of the transmitting chip from the backing of the receiving chip, avoids the excitation signal of the transmitting chip from affecting the receiving chip, thereby improving the signal-to-noise ratio of the receiving signal and facilitating signal interpretation.

Description

technical field [0001] The invention relates to the fields of medical equipment technology and health electronic products, in particular to an ultrasonic probe and a measuring instrument for measuring the thickness of subcutaneous tissue. Background technique [0002] With the improvement of people's living standards and changes in lifestyles, obesity is becoming more and more common. Obesity and the health problems it causes have become a hot spot that people pay attention to. [0003] The percentage of fat in the human body is an important indicator of health status. From the perspective of human anatomy, the human body includes superficial fascia and deep fascia throughout the body. Among them, superficial fascia, also known as subcutaneous fascia, is located under the skin and is composed of loose connective tissue, mostly containing fat; deep fascia, also known as intrinsic fascia, is located below the superficial fascia and is composed of dense connective tissue.

Problems solved by technology

[0009] However, for figure 1 For the four ultrasonic probes given, there are many useless signals in the received signals, which makes it difficult for later signal processing and interpretation, especially with detection blind spots, that is, for very thin tissue structures, it is impossible to combine useless signals with useful echo signals separate
