Individuals who have undergone lower limb amputation often struggle with excessive heat and sweating in their prosthetic sockets. This is due to the closed environment of the socket, which disrupts the body's natural cooling mechanisms and can lead to increased skin temperature, sweating, and various skin problems. This study aimed to develop a new socket to alleviate heat buildup in those with below-knee amputation.
A positive residual limb model of a below-knee amputee was used to create a new socket made of copper metal through electroforming. A cooling system was programmed so that if the temperature exceeded a predetermined threshold, the system would be activated to prevent further temperature increase. The participant wore the conventional and new socket with the cooling system, and his residual limb skin temperature was monitored using a temperature data logger.
Implementing the new socket led to a significant 5°C to 6°C reduction in temperature within the socket, greatly enhancing thermal comfort and reducing heat sensation for the users.
By incorporating the new socket and cooling system, substantial reductions in heat accumulation within the prosthetic socket can be achieved.
接受下肢截肢的个体常常在假肢接受腔内面临过热和出汗的困扰。这是由于接受腔的封闭环境扰乱了身体的自然散热机制，可能导致皮肤温度升高、出汗以及各种皮肤问题。本研究旨在开发一种新的接受腔，以减轻膝下截肢者接受腔内的热量积聚。
使用一名膝下截肢者的正位残肢模型，通过电铸工艺制作了一个由铜金属制成的新接受腔。对冷却系统进行编程，使其在温度超过预定阈值时启动，以防止温度进一步升高。参与者分别佩戴带有冷却系统的传统接受腔和新接受腔，使用温度数据记录器监测其残肢皮肤温度。
使用新接受腔后，接受腔内温度显著降低了5°C至6°C，极大地提高了热舒适度，并减轻了使用者的热感。
通过采用新接受腔和冷却系统，可以大幅减少假肢接受腔内的热量积聚。
