Abstract

The invention discloses a head and neck artery stiffness detecting system which comprises a measuring system, a photoelectric sensor, a signal processing device and a signal display device. The head and neck artery stiffness detecting system has the advantages that photoelectric pulse signals of intracranial arteries and extracranial arteries positioned in the heads and the necks of subjects can be acquired by the photoelectric pulse wave sensor for the first time, a novel idea is provided for the head and neck artery stiffness detecting system which is easy to operate and can make the subjects to feel comfortable, a plurality of different locations (such as the necks, the temple windows, the foreheads and the nose wings) which lead into the skulls of the subjects along the carotid arteries in an ascending manner can be detected by the aid of photoelectric plethysmograms, pulse wave oscillograms of the different segmental arteries can be synchronously recorded in the same cardiac cycle, accordingly, functional statuses of the intracranial arteries and the extracranial arteries can be accurately evaluated, and reliable reference foundations can be provided for warning, early screening and diagnosis for ischemic cerebrovascular diseases such as cerebral apoplexy.

Description

technical field [0001] The invention belongs to the technical field of cardiovascular and cerebrovascular detection equipment, in particular to a head and neck artery stiffness detection system. Background technique [0002] Cardiovascular and cerebrovascular diseases are major diseases that endanger human health. The World Health Organization has listed it as the number one killer that endangers human health in the 21st century. The China Cardiovascular Disease Report 2015 pointed out that there are about 290 million patients with cardiovascular diseases (including coronary heart disease, stroke, heart failure, and hypertension) in China, and they are showing a rapid growth trend. At present, the incidence of stroke in my country is at a relatively high level in the world, with an urban incidence rate of 219 / 100,000 and a rural incidence rate of 116 / 100,000 mortality. The stroke mortality rate is higher, 3.4 times that of coronary heart disease. About 75% of the 7 million...
