The utility model relates to an internal
arteriovenous fistula monitoring bracelet for a
hemodialysis patient. The internal
arteriovenous fistula monitoring bracelet comprises a bracelet main body and a bracelet
wrist strap, the bracelet main body is composed of a shell, a touch display screen, a power supply, a charging interface, a first photoelectric tube, a second photoelectric tube, a main
control circuit board, a
temperature monitoring chip and a heat insulation pad; a heat insulation pad is laid on one side, close to the inner side, of the bottom of the shell; a
temperature monitoring chip is mounted between the shell and the heat insulation pad; a sensing module is arranged on the first
wrist strap; the sensing module is provided with a first
laser, a second
laser, a third photoelectric tube, a fourth photoelectric tube, a sound sensor, a vibrating diaphragm and a
sponge. Scattering
light intensity signals generated after
laser passes through
thrombus are detected in real time through the photoelectric tube, and the
internal fistula tremor feeling is monitored in real time through the sound sensor; by adopting a photoacoustic combined detection mode, the reliability of detection is improved, the
false alarm rate of
internal fistula blockage is reduced, and the device has the advantages of simplicity in operation, portability and accurate diagnosis.
