Noninvasive hemoglobin tester and detection method thereof

Abstract

The invention discloses a noninvasive hemoglobin tester. The noninvasive hemoglobin tester comprises a detection circuit, a near-infrared light source module, an image acquisition module, a display screen and a power module, wherein the near-infrared light source module, the image acquisition module, the display screen and the power module are connected with the detection circuit respectively . The invention further discloses a detection method for the noninvasive hemoglobin tester. According to the tester, near-infrared light sources are adopted for irradiating palpebrae conjunctiva superficial layer arterial rete, reflected light is acquired to carry out blood vessel shape analysis and red depth analysis, quantity conversion is carried out on analysis results, the analysis results and standard values are compared, and hemoglobin values can be obtained quickly and accurately and directly displayed on the display screen. According to the detection method, the steps are simple, blood samples are not needed, and needed measurement values can be displayed visually and quickly in a noninvasive optical measurement mode; for the same measurement object, high-frequency multiple metering can be achieved, pains of patients are relieved, medical resources are saved, and good social value and economic value are achieved.

Description

technical field [0001] The invention relates to the technical field of hemoglobin detection, in particular to a non-invasive hemoglobin measuring instrument and a detection method thereof. Background technique [0002] Hemoglobin is the main protein in erythrocytes in the blood. Because of a certain concentration of hemoglobin in the blood, the red color we see with the naked eye appears. The higher the hemoglobin content, the deeper the red color of the blood. The function of hemoglobin is to transport oxygen and carbon dioxide. It can carry oxygen from the lungs to tissues via arterial blood, and can carry carbon dioxide produced by tissue metabolism to the lungs through venous blood and then excreted. [0003] Hemoglobin is an indispensable and important substance for the body. When the hemoglobin content drops to a certain level, it often leads to various discomforts, diseases and even death in the body. Clinically, all hemorrhagic diseases need to know the content of ...

Problems solved by technology

However, this technology has obvious limitations. First, because the measurement is the subnail vascular network, when measuring patients with hemorrhagic diseases, it will be extremely difficult to reduce the blood supply to the extremities due to the adjustment of the systemic mechanism of the human body or the regulation of the system to close the terminal microcirculat
