Embodiment 1

[0040]Please refer tofigure 1 The present application discloses an effective liver function detection device, 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 inspected part of the human body, and has the functions of transmitting and receiving multiple types of detection light. In this embodiment, the probe 11 measures the corresponding light transmittance when the detection light of the first wavelength, the detection light of the second wavelength, and the detection light of the third wavelength respectively pass through the inspected part of the human body.

[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, a body part with a small tissue layer thickness and abundant blood vessels in the tissue should be selected as the body part to be examined, such as a finger , Toes, nose w...

Embodiment 2

[0057]According to the detection device for effective liver function disclosed in the first embodiment, the calculation module in the detector needs to use a preset detection model to calculate the real-time concentration of ICG in human blood. In order to clearly understand the working principle of the calculation module, this embodiment will A detailed description of the preset detection model.

[0058]In this embodiment, the method for constructing the detection model needs to be carried out before the ICG removal test is carried out.figure 1 The probe 11 shown in Fig. 1 is connected to the body to be inspected. After the detector 12 is turned on, the detector 12 controls the probe 11 to automatically perform spectroscopic detection, and build a detection model for the human body P0 according to the detection result.

[0059]Please refer toFigure 4 The method for constructing the detection model disclosed in this embodiment may include steps S110-S130, which are described separately be...

Embodiment 3

[0099]Please refer toFigure 5 Based on the detection model disclosed in the second embodiment, this embodiment discloses an effective liver function detection method, which mainly includes steps S210-S230.

[0100]Step S210: Obtain the first spectroscopic detection data of the probe. The first spectroscopic detection data here includes the transmittance of the detection light of the first type of wavelength and the detection light of the second type of wavelength respectively passing through the inspected part of the human body after the ICG removal test is started.

[0101]For example, seefigure 1 After the ICG removal test starts, the detector 12 controls the probe 11 to continuously emit the detection light L1 of the first wavelength and the detection light L2 of the second wavelength in a certain period, and then the detector 12 receives the light intensity signal fed back by the probe 11 , Thus processed to the first type of wavelength of the detection light L1 through the human body...

Abstract

The invention discloses an effective liver function detection method and device and a storage medium. The detection method comprises the steps of obtaining first spectroscopic detection data of a probe, wherein the first spectroscopic detection data comprise the transmittance of detection light of a first type of wavelength and detection light of a second type of wavelength, passing through a detected part, after an ICG clearance test starts; inputting the first spectroscopic detection data into a preset detection model, and performing calculation to obtain ICG real-time concentration in humanblood; and carrying out linear regression analysis on the ICG real-time concentration under semi-logarithmic coordinates to obtain the ICG clearance rate in the human body. As long as the first spectroscopic detection data of the probe are input into the preset detection model, the ICG real-time concentration in the human blood can be calculated, so that the detection process of the ICG clearancetest is greatly simplified; and the detection method has the advantages that a patient is non-invasive and the real-time concentration detection performance is high.

Description

Technical field[0001]The invention relates to the technical field of medical detection, in particular to a detection method, detection device and storage medium for effective liver function.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 a peripheral vein, it can bind to plasma proteins, quickly distribute to various circulatory organs, and then circulate through liver cells. discharge. In normal people, only 3% of ICG remains in the blood after 20 minutes. Since ICG is only cleared in the body by the liver, the clearance rate of ICG is only closely related to the liver function status of the subject. In addition, the non-toxic properties of ICG also have no side effects on other organs, which greatl...
