摘要

冷療對物理治療而言是最常用的方法，大多運用在退燒與運動傷害上，其實它的應用可以更廣，泛指皮膚燒燙傷、肌肉痙攣、關節炎及腫脹疼痛等都可以巧妙運用，被抑制的原因在於市售冰敷袋的內容多為冷水或化學溶液經由冰箱冷卻後再開始使用，其冷敷的時效約為離冰箱後的半個小時以內，再次使用時又必須一小時以上的冷藏，再運用上十分不方便，且冷療過程中溫度運用不當是最常造成皮膚凍傷、神經麻痺、動作等的二次傷害主因。本研究旨在開發一新型冰敷裝置，利用致冷晶片(TEC: Thermo-Electric Cooler, 以下簡稱TEC)輕、小、無噪音等特性，裝置8051溫控套件，利用繼電器的ON/OFF來控制TEC 的溫度，再運用幫浦循環調節敷袋內的溫度，因為電力發動，只要一直供電即可達到長效的效果，且由於溫度有做控制不會造成二度傷害，經實驗測試系統在無負載時只要15分鐘即可由26℃下降至冷敷最適當的15℃，負載2瓦時也只需19分鐘，其便利性大為增加，應用範圍也較一般敷袋更廣。

The cold therapy, the most common physical therapy, is often used to bring down a fever and to cure sports injuries. Actually, the cold therapy can be used for skin burns, muscle spasms, arthritis, swellings, and pains, too.
Most of the ice packs, bought from the market, are restrained by the time duration because the cold water or phase change material in ice pack can sustain within half an hour when leaving the refrigerator. Before cold therapy, the ice packs must be stored in the refrigerator for at least an hour for the next therapy which is not convenient at all. Also, the inappropriate temperature span during the cold therapy is often the main cause of skin frostbite, nerve paralysis, motor posturing and other secondary injuries. This study aims to develop a new cooler, named “thermo-electric cooler” (TEC), which is light, small, and low noise. With the “ON/OFF” switch of the relay, the 8051 temperature control package can be installed to control the TEC temperature. Then, the temperature of the water degree inside the ice pack can be adjusted through the transport of the water pump. The continuous electricity supply helps the ice pack to maintain long performance, and the constant temperature control prevents secondary injuries from cold therapy. Without external thermal load, this cooler demonstrates that the water in ice pack takes within 15 minutes to lower the fluid temperature from 26℃ to 15℃ which is the most appropriate scale for the human body during cold therapy. When the external thermal load is 2 watts, this system takes only 19 minutes to do so. Therefore, this TEC can have broader applications than the common ice packs in a more convenient way.
