Technical Field

The invention relates to an intelligent wireless monitoring technology, in particular to an intelligent wireless monitoring method and system for arteriovenous internal fistula blood vessels.

Background

The arteriovenous fistula is mainly used for hemodialysis treatment, the hemodialysis is one of kidney replacement treatment modes of patients with acute and chronic renal failure, and the purposes of purifying blood and correcting water electrolyte and acid-base balance are achieved by utilizing the principle of a semipermeable membrane and removing various harmful and redundant metabolic wastes and excessive electrolytes in a body out of the body through diffusion. The arteriovenous internal fistula is a fine operation for anastomosis of blood vessels, wherein an artery close to the wrist of a forearm and an adjacent vein are sutured by transplanting the blood vessels to form an arteriovenous internal fistula blood vessel, so that arterial blood flows in the anastomosed vein. The arteriovenous internal fistula blood vessel can provide sufficient blood for hemodialysis treatment and guarantee the sufficiency of the hemodialysis treatment. Arteriovenous internal fistula is the most common vascular access of patients with maintenance hemodialysis, so that the vascular patency needs to be kept for a long time, thrombus is found in time, the position of the thrombus is accurately judged, and measures are taken to avoid the generation of complications.

The traditional arteriovenous internal fistula blood vessel detection method mainly comprises the following steps:

1) touching the internal arteriovenous fistula blood vessel with hands feels whether internal fistula tremor exists. Internal fistula tremor is a continuous, rapid, subtle tremor that occurs when blood flow impacts the wall of an arteriovenous internal fistula that has already been arteriosclerotic. The method needs to judge according to personal experience, and has larger misjudgment probability.

2) The method can reduce the misjudgment probability to a certain extent by adopting a professional stethoscope for diagnosis, but the use occasion is limited, and the patient can not be diagnosed in real time when not in a hospital, so that the optimal diagnosis opportunity can be missed.

3) The diagnosis is carried out by using an ultrasonic instrument, the method needs instruments and doctors with abundant experience, the use occasions are limited to the diagnosis in hospitals, the cost is high, and the real-time detection can not be carried out at any time and any place.

At present, portability or wearable monitoring devices can provide a comparatively convenient internal arteriovenous fistula vascular detection for the patient, compare in above-mentioned method, and this type of device can let the patient carry out the internal arteriovenous fistula vascular detection at home, need not to touch the method or go to the hospital through the hand and diagnose, has improved the convenience that internal arteriovenous fistula vascular detected. However, this method also has certain disadvantages. Firstly, arteriovenous internal fistula blood vessels have a certain length, thrombus may exist in any part of the blood vessels, the device can only detect data of one part of the blood vessels at the same time usually, if a plurality of parts need to be detected, the device needs to be disassembled and assembled for many times, the operation is complex and tedious, and the data of one part of the blood vessels cannot represent the condition of the whole blood vessel and the position of the thrombus is difficult to judge, so the detection precision of the method cannot be ensured, and the intelligent degree is low. Secondly, the method requires the patient to manually and actively operate the device, the patient cannot be detected when the patient is in a sleep state, and if the blood vessel blockage occurs, the patient cannot be detected and found in real time, so that the patient is easily in a life danger state, and the detection real-time performance of the method cannot meet the requirement. Moreover, such devices are generally in a wrist strap type, and if a patient wears the device for a long time, the blood vessels are easily compressed, and the blood vessels at the compressed positions become narrow or even blocked, so that the body feeling of the patient is uncomfortable, and the user experience is seriously influenced. In addition, this kind of device adopts the buckle mode to fix at patient's wrist usually, and the structure is comparatively complicated, and the hardware cost is higher, and it is also inconvenient enough to operate and use.

Referring to fig. 2, the arteriovenous internal fistula 6 includes an artery anastomosis 61 and a vein anastomosis 62, three detection points, namely, a 1 st detection point, a 2 nd detection point and a 3 rd detection point, are sequentially arranged on the skin corresponding to the arteriovenous internal fistula 6 at certain intervals along the blood flow direction (i.e., from the artery anastomosis 61 to the vein anastomosis 62), each detection point is provided with a detection device 1, and blood flow data obtained by detection of each detection point are respectively D₁、D₂And D₃. Every detection device 1 conveys the blood flow data that obtain that detect to first terminal 2 through bluetooth communication mode, and first terminal 2 can be the intelligent device of smart mobile phone, panel computer or taking BLE bluetooth screen display.

Generally, the flow of blood through an arteriovenous internal fistula is constant, and the flow of blood through each test site is also constant over a time interval. The lower limit value of the blood flow index is f1, the upper limit value of the blood flow index is f2, and when the blood flow data is between f1 and f2, the blood flow in the arteriovenous fistula is considered to be normal. Thus, in a normal state of the arteriovenous internal fistula, that is, when no thrombus is present in the arteriovenous internal fistula, the blood flow index detected by the three detection devices should be between f1 and f2, see fig. 3.

For example, when D₁F2 and D₂If f2 indicates that thrombus exists before the 1 st detection point and between the 1 st detection point and the 2 nd detection point, the blood flow data sizes of the two detection points can be continuously compared, such as D₁＞D₂Indicating that the thrombus is located close to the 1 st detection point, e.g., D₁＜D₂The thrombus is indicated to be located close to the 2 nd detection point.
