the LED module is used for driving an LED lamp on the LED module to emit light according to the light control signal.
9. The arteriovenous fistula cardio-protective belt of claim 8, wherein the pressure hemostasis and the means for activating the pressure hemostat to perform the pressurized hemostasis when the processor determines that the venous dialysis flow rate, the arterial dialysis flow rate, and the differential flow rate reach the hemodialysis hemostasis state reference value.
10. The arteriovenous fistula cardio-therapeutic belt of claim 9, further comprising a sound alarm module for triggering alarm processing and outputting alarm information through the sound alarm module when the processor judges that the venous dialysis flow rate, the arterial dialysis flow rate and the differential flow rate reach the hemodialysis danger state reference value.
