TECHNICAL FIELD
[0001] The utility model relates to the field of daily necessities, especially to a kind of auxiliary eating chopsticks for hand dysfunction patient. BACKGROUND
[0002] Stroke, brain trauma and other nervous system diseases have become a serious problem affecting the quality of life of the elderly population. Hand movement dysfunction caused by these diseases makes patients face problems such as finger fine dysfunction, insufficient grip strength, forearm supination dysfunction, wrist extension dysfunction, etc. when eating, which not only affects the dining experience, but also may cause malnutrition.
[0003] Under this background, many auxiliary eating tools have emerged on the market, aiming to help hand dysfunction patients solve the problem of eating. For example, auxiliary eating spoons with thickened handles, and auxiliary chopsticks that need to be held by finger fine grip. Although the auxiliary eating spoons on the market are suitable for liquid food, they are not suitable for solid food. The existing auxiliary chopsticks can help patients pick up solid food, but in the process of use, patients still need to have high hand fine function, such as finger extension and flexion, pinch, wrist rotation, etc. However, it is difficult for hand dysfunction patients to achieve this in actual situations. There are also other auxiliary eating tools, such as intelligent anti-shaking chopsticks, anti-shaking spoons, anti-shaking forks, etc. These devices use gyroscopes and acceleration sensors to detect hand movements and control DC motors and transmission devices through anti-shaking algorithms to achieve stable eating. However, these devices are mainly suitable for patients with hand tremors such as Parkinson's disease, and are high in cost and expensive in price, which limits their large-scale promotion in the market.
