Embodiment 1

[0040] Please refer to figure 1 , the present application discloses a detection device for effective liver blood flow, which includes a probe 11, a detector 12 and a display 13, which will be described separately below.

[0041] The probe 11 is used to be clamped on the part of the human body to be inspected, and has functions of transmitting and receiving various types of detection light. In this embodiment, the probe 11 measures the corresponding light transmittance when the detection light of the first type of wavelength, the detection light of the second type of wavelength and the detection light of the third type of wavelength respectively pass through the human body to be inspected.

[0042] It should be noted that in order to measure the absorption of detection light by substances such as hemoglobin and indocyanine green (ICG) in the blood, the parts of the body with a small tissue layer thickness and rich blood vessels in the tissue should be selected as the body parts...

Embodiment 2

[0059] Please refer to Figure 4 , this embodiment discloses a method for detecting effective liver blood flow, which includes steps S210-S240, which will be described respectively below.

[0060] Step S210, acquiring spectroscopic detection data of the probe. The spectroscopic detection data here include the transmittances of the detection light of the first type of wavelength and the detection light of the second type of wavelength respectively passing through the tested parts of the human body after the start of the ICG removal test.

[0061] For example, see figure 1After the ICG removal test starts, the detector 12 controls the probe 11 to continuously emit the detection light L1 of the first type of wavelength and the detection light L2 of the second type of wavelength at a certain period, and then the detector 12 receives the light intensity signal fed back by the probe 11 , so as to process the transmittance of the detection light L1 of the first type of wavelength p...

Embodiment 3

[0136] see Figure 11 , this embodiment discloses a detection device for effective liver blood flow, which includes a memory 21 and a processor 22 .

[0137] Wherein, the memory 21 is used to store programs, and the memory 21 can be regarded as a computer-readable storage medium, and the internally stored program can be the software code corresponding to the detection method in the second embodiment.

Abstract

The invention discloses a detection method and device for effective effective hepatic blood flow, and a storage medium. The method includes the following steps: obtaining the spectrophotometric detection data of a probe; calculating the ICG real-time concentration and ICG clearance rate in human blood according to the spectrophotometric detection data; calculating the circulating blood volume of ahuman body according to the ICG dosage and ICG real-time concentration in ICG clearance tests; and obtaining the effective hepatic blood flow through the analysis of the product of circulating bloodvolume and ICG clearance rate. Through the technical schemes, the measuring formulas of the effective hepatic blood flow (EHBF) can be simplified to a certain extent, so that calculation errors causedby some calculation parameters can be avoided, the precision of EHBF detection can be enhanced, and the reference values of EHBF indexes in clinical application can be increased; and addition, by firstly calculating the ICG clearance rate and circulating blood volume and then calculating the EHBF indexes, reliable solutions can be provided for the current clinical monitoring on the EHBF indexes by only measuring with one time.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a detection method, device and storage medium of effective liver blood flow. Background technique [0002] The main method for evaluating effective liver function is the Indocyanine Green Clearance Test (ICG Test). The detection principle of the indocyanine green clearance test is based on the pharmacological properties of indocyanine green, that is, after indocyanine green is injected into the human body through the peripheral vein, it can be combined with plasma proteins, quickly distributed to various circulatory organs, and then circulated by liver cells. discharge. In normal people, only 3% of ICG remains in the blood after 20 minutes of injection. Since ICG is only cleared in the body through the liver, the clearance rate of ICG is only closely related to the liver function status of the subject. In addition, the non-toxic property of ICG has no side effects on ...
