Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an arteriovenous fistula thrombosis detection and early warning processing device. Technical Background

[0002] Arteriovenous fistula is one of the surgical procedures, mainly used for hemodialysis treatment, that is, through surgical anastomosis of the patient's superficial veins and peripheral arteries, arterial blood can flow through the superficial veins, thereby establishing extracorporeal circulation during hemodialysis and achieving the required blood flow. After the operation, the arterial blood flowing in the superficial veins continuously impacts the blood vessel wall, causing the venous wall to expand and thicken, and the venous blood vessels to arterialize. This process is called fistula maturation. The mature veins are easy to puncture, and hemodialysis can generally be performed 4 to 8 weeks after the operation.

[0003] However, some patients are prone to occlusion within 7 days after arteriovenous fistula surgery because their blood vessels are too thin or blood clots form in their blood vessels, which can block the arteriovenous fistula and make it unable to perform its function. Therefore, it is necessary to monitor the blood flow rate at the patient's arteriovenous fistula. Normally, blood flows fast in arteries and slow in veins, while blood flows directly from arterial blood into veins at the arteriovenous fistula, forming turbulence. Through this impact turbulence, it can be confirmed whether the blood flow at the arteriovenous fistula is unobstructed and whether the blood flow rate is normal. If the blood flow is too slow, it means that there is a risk of blockage at the arteriovenous fistula, and measures need to be taken to eliminate the blood clots and keep it unobstructed.

[0004] The traditional method of detection and thrombus elimination is that medical staff regularly use a stethoscope to monitor the sound of blood impact turbulence at the fistula site flushing the inner wall of the blood vessel and touch the arterial pulse at the fistula site. Based on this, they judge whether the blood circulation at the fistula site is unobstructed and whether there is a risk of blockage based on personal experience. In the early stages of thrombus formation, medical staff can use external force to massage and pat the fistula site to vibrate away the tiny blood clots in time to achieve the purpose of clearing the blood clot.

[0051] When the device is implemented, the medical staff needs to first pass the flexible fixing belt 112 through the fixing belt loop 1133, and fix the adjustable combined fixing frame 111 on the upper limb on the fistula side. Then, by changing the position of the plug-in card 11117 inserted into the plug interface 1119, the distance between the first fixing frame 1111 and the second fixing frame 1112 can be changed, that is, the width of the adjustable combined fixing frame 111 is changed to adapt to the thickness of the upper limb on the fistula side of different patients, thereby improving the patient's experience; the blood transfusion hose is clamped in the groove of the inflatable airbag 11115 to facilitate placement and prevent the blood transfusion hose from falling off due to external force pulling, and the columnar airbag 1131 is clamped between the adjustable combined fixing frame 111 and the flexible fixing belt 112 to avoid compression on the blood vessels on the upper limb on the fistula side, and the tightness of the airbag filling is adjusted according to the patient's own experience to improve the patient's experience. The number of airbags is selected by the medical staff according to the patient's needs, and then the corresponding number of groups are installed according to the area of ​​the patient's upper limb on the fistula side that needs to be heated. The magnetic legs 114 on the component installation shell 14 are inserted and adsorbed in the strip grooves to fix the component installation shell 14 on the adjustable combined fixing frame 111, and the component installation shell 14 is connected using the connecting component 17. Then, the patch piezoelectric sensor 1232 and the vibration generating module 1332 are attached above the blood vessel on the internal fistula side, and the corresponding information collection interface 143 and the vibration interface 142 on the component installation shell 14 are connected. The patch piezoelectric sensor 1232 can receive the impact turbulence in the internal fistula blood vessel and generate different amplitudes. The digital-to-analog conversion module 122 converts these amplitude signals into digital signals, which are displayed as waveforms on the display module 121 through the microcontroller module 131. Medical staff can observe the impact turbulence in the internal fistula blood vessel, and adjust the infrared heating temperature, the amplitude frequency of the vibration generating module 1332 and other related settings through the control button 18 set on the component installation shell 14 to make adaptive adjustments for different patients and improve patient comfort.
