The invention discloses a vascular endothelial function detecting device based on fingertip temperature change. The vascular endothelial function detecting device is used in the field of medical instruments and comprises a device main machine with a main control circuit board and a function module led out from the device main machine and connected with the main control circuit board. The function module comprises a blood blocking module for controlling of brachial artery blood flowing, a temperature measuring module for measuring fingertip temperature change and an oxyhemoglobin saturation measuring module for measuring fingertip oxygen content of blood. A complex algorithm using the fingertip temperature change to deduce blood vessel diameter change rate is built in the main control circuit board, complex processes of a measuring method achieve automation and intelligentization, detecting cost and device price are reduced, most people can achieve self-management of cardiovascular health state at home, monitoring cost is effectively reduced, operation process is simplified, support can be provided for families and primary hospitals to conduct cardiovascular disease early prevention and diagnosis, and the device has great significance for early prevention of cardiovascular diseases.
Description
technical field [0001] The invention is used in the field of medical devices, and in particular relates to a blood vessel endothelial function detection device based on fingertip temperature changes. Background technique [0002] The development of cardiovascular disease is a long process, from the initial arterial endothelial dysfunction and increased arterial hardness, to the appearance of lipid streaks and atheromatous plaques visible to the naked eye on the arterial wall, and finally causing vascular stenosis or even occlusion to cause acute cardiac and cerebrovascular disease. Vascular events take about ten years to decades. Cardiovascular disease is a lifestyle disease, most of which have nothing to do with genetics, but are caused by acquired bad living habits. Among them, fast pace of life, high fat intake, smoking, obesity, lack of exercise, mental stress, etc. are the main causes of cardiovascular disease. Therefore, it has gradually become the consensus of clini...
