Abstract

The invention discloses a flexible wearable pulse blood oxygen measuring probe, belonging to the field of biological information detection. The invention aims to solve the problem that an existing pulse oximeter is difficult to realize flexible wearing. The flexible wearable pulse blood oxygen measuring probe comprises a flexible substrate, at least two light emitting units arranged on the flexible substrate, a detection unit arranged on the flexible substrate, and a packaging layer arranged on the flexible substrate. According to the invention, organic light-emitting diodes serve as the light-emitting units, an organic photoelectric detector serves as the detection unit, and oxyhemoglobin saturation is obtained through photo plethyamo graphy; and the probe has the characteristic of full flexibility, is accurate in testing, and better meets the requirements of wearable equipment.

Description

technical field [0001] The invention belongs to the technical field of biological information detection, and in particular relates to a flexible and wearable pulse oximetry probe. Background technique [0002] Whether the human body can dissolve enough oxygen in the blood is crucial to sustaining life. Timely monitoring whether the oxygen content in the arterial blood is sufficient is the key to judging whether there are obstacles in the human respiratory system and circulatory system or whether the surrounding environment is hypoxic. In the circulatory system, hemoglobin is an important part of blood cells that are responsible for transporting oxygen from the lungs to other tissues in the body. The amount of oxygen contained in hemoglobin at any moment is called blood oxygen saturation (OxygenSaturation, abbreviated as SO2), and blood oxygen saturation is expressed as a percentage. It is the ratio of the oxygen content of hemoglobin to the oxygen-carrying capacity of hemogl...
