Embodiment 1

[0027] Example 1: A non-invasive hemoglobin concentration level measurement device based on color properties using transmitted light beams, such as figure 2 shown.

[0028] The light source assembly adopts a halogen lamp or LED light source with continuous emission power in the range from visible light to near-infrared spectrum; the light source is collimated and irradiated to the fingertips of the human body to generate a transmitted beam; the transmitted beam is then produced by The color sensor assembly receives; the color sensor assembly consists of two beam splitting prisms plus three independent X, Y, Z sensors, where the spectral sensitivity responses of the X, Y, Z sensors are the same as the standard observer spectral sensitivity of the CIE1931XYZ system, Therefore, the CIEXYZ standard tristimulus value XYZ signal can be obtained in real time. The tristimulus value XYZ signal is processed by the data processing and calculation unit: first calculate the standard chro...

Embodiment 2

[0032] Embodiment 2: A non-invasive hemoglobin concentration level measurement device based on color characteristics using reflected light beams, such as image 3 shown.

[0033] The light source component adopts a halogen lamp with continuous emission power in the range from visible light to near-infrared spectrum, and adopts a set (3 pieces in total) of XYZ filters that can be switched quickly; the spectral transmittance of the XYZ filters is The curve is the same or similar to the standard observer spectral sensitivity curve of the CIE1931XYZ system; the above-mentioned light source is collimated and illuminates the surface of the human palm, and generates a reflected beam; the reflected beam is then received by a unit photoelectric sensor, and the spectral sensitivity of the unit photoelectric sensor The response curve is as flat as possible in the visible spectrum, and it can produce XYZ signal of tristimulus value of CIEXYZ standard after it is combined with light source...

Abstract

The invention discloses a noninvasive Hb (haemoglobin) concentration level measurement device based on color characteristics, belongs to the fields of novel digital medical detection and monitoring instruments, spectral measurement, chroma measurement, photometric measurement and the like, and particularly relates to non-intrusive human Hb concentration level measurement. According to the noninvasive Hb concentration level measurement device based on the color characteristics, information about the human Hb concentration level can be rapidly obtained in real time by color measurement for partssuch as fingertips, palms, limbs, face, eyelids and the like of a human body. Based on the device, a completely noninvasive Hb monitoring or detecting instrument can be designed and manufactured, andhas the advantages of being real-time, rapid and convenient, needing no consumables and being free of adverse side effects. The measurement device mainly comprises a light source assembly, a color sensor assembly, a data processing and calculating unit and the like.

Description

technical field [0001] The invention belongs to the fields of novel digital medical detection instrument, photoelectric detection instrument, spectrum measurement, chromaticity measurement and the like, and particularly relates to a non-invasive detection or monitoring technology of human hemoglobin Hb (Haemoglobin) level. Background technique [0002] Detection or monitoring of human hemoglobin concentration level is one of the routine inspection items in clinical diagnosis and treatment, and it has high clinical value in anemia diagnosis, disease assessment, treatment guidance and curative effect observation. At present, invasive laboratory testing methods are mainly used to measure hemoglobin concentration clinically. The measurement results are accurate and reliable, which is the standard for clinical hemoglobin concentration detection. However, it is painful and the analysis cycle is long and it is difficult to monitor in real time. In recent years, with the vigorous de...
