Intelligent wireless monitoring method and monitoring system

Abstract

The invention discloses an intelligent wireless monitoring method and system, and the method comprises the following steps: S100, arranging a plurality of detection points at intervals on the skin corresponding to an internal arteriovenous fistula blood vessel, arranging a detection device at each detection point, and enabling the detection devices to be in wireless communication connection with a first terminal; S200, the first terminal obtaining the blood flow data and judging whether the blood flow data conforms to the blood flow index or not; if the blood flow data of all the detection points conform to the blood flow index, judging that the blood vessel state is normal; if the blood flow data of any detection point does not conform to the blood flow index, judging that the blood vessel state is abnormal, and entering the step S300; S300, the first terminal judging the thrombus position according to the distribution of the detection points which do not conform to the blood flow index and the blood flow data; and step S400, the first terminal sending out warning information. The blood vessel state and the thrombus position can be judged according to the blood flow data of different parts of the internal arteriovenous fistula blood vessel, and the blood vessel problem can be found in time.

Description

technical field [0001] The invention relates to intelligent wireless monitoring technology, in particular, an intelligent wireless monitoring method and monitoring system for arteriovenous fistula blood vessels are designed. Background technique [0002] Arteriovenous fistula is mainly used for hemodialysis treatment. Hemodialysis is one of the renal replacement therapy methods for patients with acute and chronic renal failure. Using the principle of semi-permeable membrane, through diffusion, various harmful and redundant metabolic wastes and excessive The electrolytes are removed from the body to purify the blood, correct the water-electrolyte and acid-base balance. Arteriovenous fistula is a fine operation of vascular anastomosis. The artery near the wrist of the forearm and the adjacent vein are sutured by grafting blood vessels to form an arteriovenous fistula vessel, so that arterial blood flows in the anastomotic vein. Arteriovenous fistula blood vessels can provide ...

Problems solved by technology

This method needs to be judged based on personal experience, and there is a greater chance of misjudgment

[0005] 2) Using a professional stethoscope for diagnosis. This method can reduce the probability of misjudgment to a certain extent, but its use is limited. When the patient is not in the hospital, real-time diagnosis cannot be performed, which may lead to missing the best time for diagnosis

[0006] 3) Use ultrasonic equipment for diagnosis. This method requires the help of equipment and experienced physicians. Its use is also limited to diagnosis in hospitals, which is expensive and cannot be used for real-time detection anytime and anywhere.

But this method also has some shortcomings

First of all, arteriovenous fistula blood vessels have a certain length, and thrombus may exist in any part of the blood vessel. Usually, this type of device can only detect the data of one blood vessel at the same time. It is more complicated and cumbersome, and the data of only one blood vessel cannot represent the whole blood vessel condition, and it is difficult to judge the position of the thrombus. Therefore, the detection accuracy of this method cannot be guaranteed, and the degree of intelligence is also low.

Secondly, this method requires the patient to actively operate the device, and when the patient is in a sleep state, it cannot be detected. If a blood vessel blockage occurs at this time, it cannot be detected in real time, and it is easy to cause the patient's life to be in a state of danger. Therefore, the detection of this method Real-time can not meet the requirements

Moreover, this type of device is generally wrist-worn. If the patient wears it for a long time, it is easy to cause compression on the blood vessel, but the blood vessel at the compressed place becomes narrow or even blocked, causing the patient to feel uncomfortable and seriously affecting the user experience.

In addition, this type of device is usually fixed on the patient's wrist by means of a buckle, the structure is more complicated, the hardware cost is higher, and the operation and use are not convenient enough.
