Internal arteriovenous fistula maturation trainer with protective structure

Abstract

The invention discloses an internal arteriovenous fistula maturation training device with a protective structure, which comprises a holding frame, a movable rod and a protective frame, the holding frame comprises an operating rod and an extension spring, the extension spring is mounted at the head of the operating rod and is rotatably connected with the operating rod, the movable rod is mounted in the middle of the operating rod, and the protective frame is mounted in the middle of the operating rod. The movable rod is rotationally connected with the operating rod, an adjusting mechanism for adjusting the length of the extension spring is further installed on the lower end face of the movable rod, the adjusting mechanism is rotationally matched with the movable rod through threads, the extension spring is sleeved with the protective frame, and the protective frame is fixedly connected with the operating rod; it is guaranteed that a patient can conveniently conduct holding training through running fit between the holding frame and the movable rod, and it is guaranteed that good elastic tension can be achieved between the holding frame and the movable rod by installing the extension spring between the holding rod and the horizontal plate, so that the good training effect of the patient can be guaranteed; and an adjusting mechanism is mounted in the transparent threaded sleeve.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training equipment for arteriovenous fistula patients, in particular to an arteriovenous internal fistula maturation trainer with a protective structure. Background technique [0002] Arteriovenous fistula is the most commonly used vascular access for maintenance hemodialysis patients, which can provide sufficient blood for hemodialysis treatment and provide guarantee for the adequacy of dialysis treatment. Therefore, arteriovenous fistula is aimed at many patients who need hemodialysis. Surgery is common. [0003] The Chinese patent with the patent number of CN205379605U discloses an arteriovenous fistula function trainer, which includes an arm bracket, a display panel, an electronic gripping device and an adjusting member. The display panel is provided with a display, and the electronic gripping device is provided with a on the arm bracket and connected with the display; the adjusting me...

Problems solved by technology

[0004] However, in the actual use process, the above-mentioned arteriovenous fistula training equipment has a simple structure, and can only be used for training with a fixed strength in the actual use process, so that when different patients and the same patient have different recovery periods, they cannot be trained according to needs. It is less flexible to use. At the same time, the traditional arteriovenous fistula training equipment has no corresponding protective structure. In this way, once the two ends of the spring are disconnected after long-term use, it is easy to cause the spring to splash, which is easy to give Patient use poses a greater threat, resulting in less secure equipment
