Multifunctional wristband for monitoring internal arteriovenous fistula of hemodialysis patient

Abstract

The invention relates to a multifunctional wristband for monitoring an internal arteriovenous fistula of a hemodialysis patient. The multifunctional wristband for monitoring the internal arteriovenousfistula of the hemodialysis patient comprises a wrist strap, wherein an internal fistula monitoring module and a temperature sensor are located on a skin side of the wrist strap, the internal fistulamonitoring module comprises an internal fistula natural blood flow volume monitor, a vascular wall thickness monitoring module and an internal fistula tremor and internal fistula pulsation monitoringmodule, and an alarming device, a display, a wireless communication module and a controller are arranged on the wrist strap. The multifunctional wristband for monitoring the internal arteriovenous fistula of the hemodialysis patient can detect the natural blood flow volume, tremors and pulsation of the internal fistula, the vascular wall thickness and the body temperature of the hemodialysis patient, and can protect the internal fistula from trauma at the same time to prevent pseudoaneurysm, so that the internal fistula is subjected to good monitoring, protection and remote management, and the life of a lifeline (vascular access) is prolonged; the multifunctional wristband for monitoring the internal arteriovenous fistula of the hemodialysis patient can give different alarming prompts according to different situations to remind the patient of timely medical treatment, so that timely rescue of the internal fistula is facilitated; and an elastic buffering layer is arranged on the innersurface of the wrist strap, and has a buffering function when the internal fistula part is under external attack, and then damage to functions of the internal fistula and local massive hemorrhage areprevented, so that the elastic buffering layer plays a role in effectively protecting the internal fistula.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional monitoring wristband for arteriovenous fistula of hemodialysis patients. Background technique [0002] The incidence of chronic kidney disease is increasing year by year, and maintenance hemodialysis is one of the important life-sustaining treatments for patients with end-stage renal disease. To carry out hemodialysis treatment, the first condition is to have a functioning vascular access. Without vascular access, hemodialysis patients cannot undergo dialysis treatment, so vascular access is called the "lifeline" of hemodialysis patients. Compared with other vascular access (such as temporary or long-term central venous catheter), autogenous arteriovenous fistula has the advantages of longer use time and fewer complications, and is the preferred vascular access method for dialysis treatment. [0003] At present, in order to monitor the condition of aut...

Problems solved by technology

[0005] Due to the low level of self-management of arteriovenous fistula in hemodialysis patients and poor compliance, resulting in occlusion and failure of arteriovenous fistula, hemodialysis cannot be performed, and re-catheterization and re-operation to establish arteriovenous fistula are required, which greatly increases the number of patients.
