AI Technical Summary
Existing arteriovenous fistula exercisers rely on patients to clench their fists and exercise, which makes it difficult to ensure compliance and control of force, resulting in slow fistula maturation and increased risk of complications. They are particularly impractical for special patients such as the elderly or those who are physically weak.
A fistula exerciser is designed to simulate the clenching motion of the hand through joints and elastic components. The elastic deformation of the elastic components provides resistance, promotes blood circulation and vasodilation, and includes elastic components, stabilizing pads and soft finger sleeves to adapt to the needs of different patients.
It can improve blood flow and maturity of arteriovenous fistulas, reduce the risk of thrombosis and vascular stenosis, prolong the lifespan of arteriovenous fistulas, and increase patients' exercise experience and compliance.
