Aortic artery measuring probe, device and method of measuring diameter of aortic artery

Abstract

An aortic artery measuring probe, device and a method of measuring the diameter of the aortic artery are provided. The aortic artery measuring device includes the aortic artery measuring probe and a signal processing module electrically connected to the aortic artery measuring probe. The aortic artery measuring probe includes a flexible substrate and a sensor array disposed thereon, wherein the sensor array includes M×N ultra-wideband sensors. The ultra-wideband sensors is positioned on a subject and the flexible substrate is deformed to a profile conforming to the profile of the subject. The ultra-wideband sensors transmit a radio wave into the subject and then the radio wave is reflected by a tissue interface of the artery wall of the aortic artery to form a reflected signal. The ultra-wideband sensors receive the reflected signal and the signal processing module analyzes the reflected signal to define the diameter of the aortic artery.

Description

technical field [0001] The invention relates to a measuring probe, a device and a measuring method, and in particular to an aortic vessel measuring probe, an aortic vessel measuring device and a measuring method for the diameter of the aortic vessel. Background technique [0002] In advanced European and American countries, aortic aneurysm has been listed as the top ten cause of death for people over 55 years old. Taking the United States as an example, about 15,000 people die each year from aortic aneurysm rupture or dissection. In a large-scale screening study, male smokers showed a high risk of aortic aneurysm (abdominal aortic aneurysm diameter > 3cm up to 6.3%), compared with never smokers (abdominal aortic aneurysm diameter > 3cm approximately 1.3%), the risk is five times higher; while the diameter of abdominal aortic aneurysm > 3cm is only about 1.5% in the female smoking group. [0003] Currently, there are three types of measurement devices for the aorta...

Problems solved by technology

[0005] (1) Although the ultrasound measurement is accurate and the cost of the health examination is low (only about 55 US dollars), it is not easy to screen obese people due to the interference of the air in the stomach, and there will be image interpretation during the implementation Difficulties and other problems require the experience and expertise of technicians

Moreover, when ultrasound examinations are generally performed, most of the organs located in the abdomen are examined, and the abdominal aorta is not specifically measured;

[0006] (2) CT and NMRI examinations are expensive and time-consuming, and there are problems such as radiation and drug allergies, which are not suitable for general health examination screening, and currently national health insurance does not pay for these two screenings. You need to pay for expensive inspections at your own expense, so it is difficult for the public to accept these two detection methods
