Internal arteriovenous fistula maturation promoting training device

Abstract

The invention discloses an internal arteriovenous fistula maturation promoting training device, and relates to the technical field of medical instruments, the internal arteriovenous fistula maturation promoting training device comprises a supporting seat, a rotating assembly, a stretching assembly and a spacing adjusting assembly, two clamping assemblies are installed on the spacing adjusting assembly, and a driving assembly is installed between the two clamping assemblies; a training assembly is installed at the end, away from the rotating assembly, of the interval adjusting assembly. The clamping assembly comprises a clamping frame installed on the distance adjusting assembly, a first gear ring is installed on the clamping frame, a first supporting table and two clamping heads are installed on the clamping frame in a sliding mode, and adjusting units are installed on the first supporting table and the clamping heads. Through the clamping assembly, the training amplitude of the arms of the postoperative patient can be limited, and wound cracking caused by too large amplitude is prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a training device for promoting maturation of arteriovenous fistula. Background technique [0002] Arteriovenous fistula is the most commonly used vascular access for patients with maintenance hemodialysis. It can provide sufficient blood for hemodialysis treatment and guarantee the adequacy of dialysis treatment. Therefore, for many patients who need hemodialysis, arteriovenous fistula Surgery is very common. Whether the internal fistula can develop and mature within 1-2 months after the operation is the key to determining whether dialysis treatment can be carried out in the later stage; the traditional internal fistula exercise method is mainly a plastic grip ring, which is not effective enough during exercise. When the patient's training range is too large, it is easy to cause wound dehiscence, which is not conducive to the continued treatment after surgery. [0003] ...

Whether the internal fistula can develop and mature within 1-2 months after the operation is the key to determining whether dialysis treatment can be carried out in the later stage; the traditional internal fistula exercise method is mainly a plastic grip ring, which is not effective enough during exercise.

[0003] The patent with the publication number "CN205379605U" proposes an arteriovenous fistula functional trainer, which includes an arm bracket, a display panel, an electronic grip and an adjustment piece, the display panel is provided with a display, and the electronic grip is set on the arm bracket and connected with the display; the adjustment member is connected with the bottom surface of the arm bracket for adjusting the height of the arm bracket; although this patent can assist the patient to perform simple training, it cannot be used for training. If the range is limited, it is easy to cause the training range to be too large and cause the wound to dehisce. At the same time, the patented training method is less and cannot adapt to the needs of different patients.
