Embodiment 1

[0043] see figure 1 , the present embodiment is a human body microcirculation blood perfusion detector, which includes a laser module 10, an optical probe 20, a detection module 30, a signal processing module 40 and a user interface module 50; wherein,

[0044] The laser module 10 is configured to transmit a laser signal of a preset wavelength to the optical probe 20;

[0045] The optical probe 20 is used to contact the surface of human tissue, transmit the laser signal emitted by the laser module 10 to the human tissue, and transmit the optical signal with Doppler frequency shift signal reflected by the human tissue to the detection module 30 ;

[0046] The detection module 30 is used to convert the optical signal with the Doppler frequency shift signal transmitted by the optical probe 20 into a corresponding electrical signal, and transmit it to the signal processing module 40;

[0047] The signal processing module 40 is configured to extract a Doppler frequency shift sign...

Embodiment 2

[0063] see image 3 , corresponding to Embodiment 1, Embodiment 2 proposes a human microcirculation blood perfusion detection method, which mainly includes the following steps S100 to S500:

[0064] S100, emitting a laser signal of a preset wavelength for detecting blood perfusion of human tissue;

[0065] S200. Receive reflected optical signals with Doppler frequency shift signals from multiple directions;

[0066] S300. Convert the optical signal with the Doppler frequency shift signal into a corresponding electrical signal;

Abstract

The invention relates to a human microcirculation blood perfusion detecting instrument and method. The detecting instrument comprises a laser module, a light probe, a detecting module, a signal processing module and a user interface module. The laser module emits laser signals of preset wavelength to the light probe. The light probe transmits the laser signals emitted by the laser module to human tissue and transmits light signals reflected by the human tissue to the detecting module. The detecting module converts the light signals transmitted by the light probe into corresponding electric signals and transmits the electric signals to the signal processing module. The signal processing module extracts Doppler shift signals from the electric signals and calculates blood perfusion according to the Doppler shift signals. The user interface module displays the blood perfusion visually. The detecting instrument can help doctors or related medical staff find the situation in time and take effective treatment measures when microcirculation disturbance happens to a patient, and therefore health of the patient is ensured.

Description

technical field [0001] The invention relates to the technical field of biomedical detection, in particular to a human body microcirculation blood perfusion detection instrument, which can non-invasively detect the microcirculation blood perfusion of human tissue, and also relates to a detection method correspondingly. Background technique [0002] Microcirculation is the blood circulation in capillaries between arterioles and venules. It is the most basic structural and functional unit in the human circulatory system. As a way for human blood to exchange substances with various tissues and cells, it is responsible for supplying , Each tissue cell provides oxygen, nutrients, transfers energy, discharges carbon dioxide and metabolic waste, etc. Therefore, the clinical measurement of human microcirculation plays an important guiding and auxiliary role in judging whether various tissues of the human body are healthy and in treating diseases. [0003] Especially in the Intensive ...
