Embodiment Construction

[0027] The present invention will be further elaborated below through specific embodiments in conjunction with the accompanying drawings.

[0028] Such as figure 1 As shown, the arterial hemangioma rupture early warning system integrated with blood pressure and hemangioma deformation monitoring in this embodiment includes: the implanted part in the body includes a strain sensor, a pair of temperature sensors, a Wheatstone bridge and a near-field communication unit in the body; the strain sensor and The temperature sensors are all ultra-thin and flexible sensors. The strain sensor is attached to the surface of the hemangioma of the arterial vessel, and a pair of temperature sensors are respectively attached to the upstream and downstream surfaces of the hemangioma of the arterial vessel; the strain sensor and three resistance values The constant resistance forms a Wheatstone bridge, and the two output terminals of the Wheatstone bridge are electrically connected to the near-fie...

Abstract

The invention discloses an early warning system for ruptured artery hemangioma and an early warning method thereof. According to the invention, an ultrathin flexible sensor, ultrathin flexible temperature sensors and an ultrathin flexible strain sensor are implanted into the body through minimally invasive surgery; the strain sensor is wound and attached to the position of the hemangioma; the temperature sensors are wound and attached to the equidistant positions upstream and downstream the hemangioma; the early warning system has ultrahigh biological compatibility and will not cause internal rejection reaction; the sensors are directly and tightly attached to the measured positions and can be used for timely and accurately measuring the measured parameters; the ultrathin flexible characteristics of the sensors will not cause new focus by resulting in external damage to blood vessels and tissues; the signal is transmitted to a mobile terminal in the manner of near field communication; a microprocessor in the mobile terminal has an alarming function; when a deforming value or local blood pressure value of the hemangioma exceeds a threshold value, the microprocessor can alarm, so that the early warning system can conveniently monitor and measure early warning for a long time.

Description

technical field [0001] The invention belongs to the field of flexible medical devices, and in particular relates to an arterial hemangioma rupture early warning system and an early warning method for comprehensive monitoring of blood pressure and hemangioma deformation. Background technique [0002] Pathological expansion of the aorta, exceeding 50% of the normal vessel diameter, is called an aortic aneurysm. Once the aortic aneurysm ruptures, it will cause a "volcanic eruption" of aortic blood. Once it ruptures, it will cause severe internal bleeding. Most patients are often too late to be treated. They will go into hemorrhagic shock in a short period of time, and even die at the scene. The mortality rate is about 70%. Even if it is sent to the hospital, the success rate of the operation is only 50%, and the postoperative mortality rate of the patients who survived the rescue also reaches 40% to 70%. The incidence of abdominal aortic aneurysm has increased significantly in...
