Carotid duplex ultrasound hemodynamic monitor

Abstract

The invention discloses a carotid duplex ultrasound hemodynamic monitor, comprising a support structure and an input-output device and a central programmed controller connected with each other. A monitoring program is preset in the central programmed controller. The input-output device comprises a probe. A flow speed probe comprises a Doppler flow speed sensor, a type B ultrasound two-dimensional image sensor, a continuous wave generator, a receiving / amplifying / detecting circuit, a first ultrasonic chip transducer and a second ultrasonic chip transducer. The carotid duplex ultrasound hemodynamic monitor saves medical resources and improves stroke warning accuracy; internal carotid arterial blood speed is measured under the accurate navigation of color Doppler ultrasound by using a hemodynamic method, thus solving the problem of blind detection for a cerebrovascular hemodynamic detection flow speed probe; detection image stability and reliability are guaranteed by adding a foot-operated freezing method of probe detection operations; stroke warning sensitivity is improved by integrating morphological examination to hemodynamic examination.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a cervical blood vessel color ultrasound hemodynamic monitor. Background technique [0002] At present, cardiovascular and cerebrovascular diseases are a serious threat to human life and health with their high morbidity, high mortality and younger trends. 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. In my country, the death caused by cardiovascular and cerebrovascular diseases also accounts for about 50% of the total death causes. [0003] At present, for patients who have had a stroke, commonly used clinical diagnostic methods such as MRI (magnetic resonance imaging), CT (computed tomography), etc., are instruments for detecting morphological changes in brain tissue through imaging. The lesion and nature of stroke can be located...

Problems solved by technology

[0004] 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 has peripheral devices (such as printers) at the same time, moving will become more difficult; monitoring The instrument is used to monitor carotid atherosclerotic plaque, carotid intima, media thickness, diameter stenosis color ultrasound probe and cerebrovascular hemodynamics detection flow velocity probe and other probes are set separately, which often makes a monitor drag several times. A probe not only affects the appearance, but also easily causes a waste of resources; the existing monitors usually use the cerebral blood vessel hemodynamics to detect the flow velocity probe for blind testing, which affects the monitoring accuracy; only supports the probe detection method, and needs to be held while pressing the button manually Probes, if the overall coordination is not good, it is easy to affect the stability of the detection graphics generated by the terminal
