Internal arteriovenous fistula monitoring bracelet

Abstract

The internal arteriovenous fistula monitoring bracelet comprises a wrist strap and a monitoring host, the monitoring host comprises a host shell, a display screen, a monitoring system and a power supply, and the monitoring bracelet is characterized in that connecting lugs are symmetrically arranged on the two sides of the host shell, and the two ends of the wrist strap are connected to the connecting lugs through adjustable connecting mechanisms respectively; a storage, a reminding unit and a display screen in the monitoring system are connected with a processor, the display screen is a touch display screen with an interaction function, a power source is connected with the processor, the storage and the reminding unit through a switch to supply power, and a blood flow sensor is arranged in the center of the bottom of a shell. A plurality of temperature sensors are evenly distributed around the blood flow sensor in the circumferential direction, and the blood flow sensor and the temperature sensors are connected with the processor. Whether the internal arteriovenous fistula part of a patient is infected or not can be found in time through skin temperature monitoring, whether the internal arteriovenous fistula part of the patient is narrow or not and blood flow is unsmooth or not can be found in the early stage through blood flow monitoring, and internal fistula occlusion is reduced.

Description

technical field [0001] The invention relates to an arteriovenous fistula monitoring bracelet, which belongs to the technical field of medical monitoring equipment. Background technique [0002] Uremic patients need a vascular access to connect to the blood line for dialysis during dialysis treatment, and arteriovenous fistula is currently the preferred type of vascular access for end-stage renal disease patients undergoing hemodialysis. Usually, before dialysis, the doctor will surgically anastomose the arteriovenous to form an arteriovenous fistula. After 4-8 weeks, the fistula matures and can be used for puncture for dialysis. The blood vessels of the arteriovenous fistula need to provide sufficient blood for the hemodialysis treatment, so as to guarantee the adequacy of the dialysis treatment. [0003] However, clinically, due to factors such as abnormal vascular anatomy, dialysis hypotension, and excessive pressure on the puncture point after dialysis, problems such as ...

Problems solved by technology

[0004] At present, clinical monitoring is mainly to detect whether the arteriovenous fistula is unobstructed by auscultating the tremor of the fistula opening and the venous end with a stethoscope, but this detection method requires certain professional skills, and patients usually need to go to the hospital for detection, and real-time detection is not possible. The phenomenon of untimely monitoring and incomplete monitoring often occurs, which poses certain safety hazards for patients
