Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an internal fistula training device for hemodialysis patients. Background Art

[0002] Chronic kidney disease is one of the important public health issues affecting my country and even the world. Once chronic kidney disease progresses to end-stage renal disease, renal replacement therapy such as hemodialysis, peritoneal dialysis or kidney transplantation is needed to maintain life, which brings heavy economic and social burdens.

[0003] Autologous arteriovenous fistula is the preferred long-term vascular access for maintenance hemodialysis patients. Usually, after undergoing arteriovenous fistula surgery, patients need to cooperate with functional exercises to promote the maturation of the fistula function. Currently, commonly used fistula training devices use grip balls or handgrips to rely on patients' independent training to promote the maturation of the fistula. For example, patent CN213252850U discloses an arteriovenous fistula functional training device, including a grip ball part and a booster part, the grip ball part includes a grip ball body, the booster part includes a cuff, an inflation tube and a shell, the inflation tube connects the cuff and the shell, the grip ball is detachably connected to the cuff through a connecting belt, so that the grip ball can be used alone or together with the booster part, thereby achieving the technical purpose of promoting upper limb blood circulation and increasing the blood pressure load in the blood vessels.

[0004] However, since the primary diseases of maintenance hemodialysis are mainly diabetes and hypertension, and most of the patients are middle-aged and elderly, the initial vascular conditions of the established autologous arteriovenous fistula are poor. On the one hand, it is difficult to complete independent training due to physical limitations, and on the other hand, the patient's vascular condition is poor, which can easily cause damage to the fistula.
