Carotid duplex ultrasound hemodynamic monitoring system

Abstract

The invention relates to the technical field of medical automatic equipment, particularly a carotid duplex ultrasound hemodynamic monitoring system. The carotid duplex ultrasound hemodynamic monitoring system comprises a supporting structure, and an input output apparatus and a central program type control apparatus in mutual connection; a monitoring program is preset in the central program type control apparatus; the input and output apparatus comprises a probe; and a flow speed probe comprises a Doppler flow speed sensor, type B ultrasonic wave two-dimensional image sensor, a pre-amplification electric circuit, a filtering circuit, a main amplifier, an A/D conversion circuit, a controller and a wireless transmission module. According to the scheme, under accurate guidance of color ultrasound, internal carotid blood flow speed is measured by using a hemodynamic method, so that the problem of blind measurement of a brain blood vessel hemodynamic detection flow speed probe is solved; apedal type freezing method of a probe detection operation is added, so that stability and reliability of a detected pattern are ensured; by virtue of a wireless transmission module, signal wireless transmission is realized; and the carotid duplex ultrasound hemodynamic monitoring system is simple in structure, convenient to operate, and high in practicability.

Description

technical field [0001] The invention relates to the technical field of medical automation equipment, in particular to a neck blood vessel color ultrasound hemodynamic monitoring system. Background technique [0002] As we all know, with the continuous improvement of people's living standards, changes in lifestyle and diet structure, changes in habits and high-paced life lead to cardiovascular diseases such as hypertension and coronary heart disease becoming common and frequently-occurring diseases. Cardiovascular and cerebrovascular diseases seriously threaten human life and health with its high morbidity, high mortality and younger trend. Vascular diseases are the number one killer of human health. The number of people who die of cardiovascular and cerebrovascular diseases in the world is as high as 15 million every year. The death caused by cardiovascular and cerebrovascular diseases also accounts for about 50% of the total death causes. [0003] At present, for patients ...

AI Technical Summary

Problems solved by technology

However, the current cardiovascular and cerebrovascular disease monitors are generally fixed together with other medical equipment, which is inconvenient when they need to be moved separately, especially when the monitor also has peripheral equipment (such as a printer), moving will become more difficult; The monitor is used to monitor carotid atherosclerotic plaque, carotid intima and media thickness, stenosis color ultrasound probe and cerebrovascular hemodynamics detection flow velocity probe and other probes are set separately, which often makes one monitor drag Several probes not only affect the appearance, but also easily cause waste of resources; the existing monitors usually use the cerebral blood vessel hemodynamics to detect flow rate probes for blind testing, which affects the monitoring accuracy; only supports the probe detection method, which needs to be held manually while pressing the button If the overall coordination is not good, it will easily affect the stability of the detection graphics generated by the terminal
