Microcirculation in meridian skin tissue real-time monitoring method, system and probe head

Abstract

The utility model is applicable to the field of medical device and provides a microcirculation in meridian skin tissue real-time monitoring method, system and probe head. The method comprises the following steps: firstly, computer controls laser device to output laser according to certain frequency; secondly, the laser is conducted to probe head through optical fiber so as to irradiate tissue to be measured; thirdly, ultrasonic transducer inside the probe head receives ultrasonic signals generated by the tissue, and then transmits the ultrasonic signals back to computer; finally, the computer generates images according to the ultrasonic signals in the tissue. The embodiment can obtain microcirculation information in meridian skin tissue by utilizing photocoustic imaging technology, solve the problem of real-time monitoring of microcirculation in meridian skin tissue and provides basis or guidance for early diagnosis and treatment of related diseases. The microcirculation in meridian skin tissue real-time monitoring method, system and probe head is characterized in that photocoustic imaging is performed towards the meridian skin tissue in the process of acupuncture without moving the probe head and tissue so that real-time monition of microcirculation in meridian skin tissue is achieved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a real-time monitoring method, system and probe for microcirculation in skin tissue at acupoints. Background technique [0002] According to the classical theory of traditional Chinese medicine, acupuncture must target specific parts (acupoints) for treatment. Therefore, it has been the core issue of research in this field to study the changes of microcirculation characteristics of acupoint tissues during the treatment process, and to establish an evaluation model based on these indicators. Scholars have made a lot of progress in this field by using optical methods. At present, the main methods are laser speckle imaging (LASCI, Laser speckle contrast imaging) and laser Doppler imaging (laser doppler perfusion imaging). However, the detection depth of laser speckle imaging and laser Doppler imaging cannot reach the centimeter level, so the above methods can only be use...

Problems solved by technology

At the same time, because the light source needs to irradiate the acupuncture area, it is impossible to realize real-time monitoring of the microcirculation in the skin tissue of the acupuncture points.

Solution C, although a good solution to the problem of signal detection, but because the transducer is placed directly above the tissue and close to the tissue, the light source and transducer must be removed during the acupuncture project, which brings 2 A question: 1. It can only detect changes in tissue microcirculation before and after acupuncture, but cannot monitor changes in tissue microcirculation during acupuncture
