摘要: | 自從2015年的八仙塵暴事件發生,燒燙傷在臺灣受到高度的重視。其復健方式是利用壓力衣施予皮膚壓力以抑制增生疤痕。此外,燒燙傷患者主要以兒童與青少年居多。若燒燙傷產生之疤痕未受到良好的治療與復健,不僅會面臨永久性的增生疤痕造成關節攣縮及變形等問題,還會造成心理上的傷害。對於正值發育期間之兒童與青少年,壓力衣之過度施力對於皮膚與骨骼生長會造成影響。壓力衣之製作乃基於過去之文獻,而這些資料皆是大人的數據,其適用於兒童與青少年與否依然有待商確。
為達成可量測孩童指關節等小型部位之壓力衣的施力,本研究目標即是開發一個微型壓力動態量測系統。本研究參考了目前臺灣之陽光基金會的醫療人員使用之感測儀器Pico Press® (MICROLAB),將其可攜式與簡易操作之優點納入考量,並再增加感測微小化與動態量測之功能,開發出適用的壓力量測系統。 除了感測元件之微小化外,本論文利用液壓達成遠比Pico Press®壓力感測器更高的頻寬,且以市售9V乾電池供電達成低功耗、可攜式且具備壓力信號輸出之功能,所有特性也均已校正及證實合乎當初設計之目標規格。所完成的量測設備對未來設計更新型的的壓力衣將不可或缺。 A total of 15 persons had been killed and 484 persons were severely burned since the explosion of Formosa Fun Coast water park in 2015. Treatments of burns have gained much more attention in Taiwan. The rehabilitation for patients burned is to wear pressure garment to prevent hypertrophic scars recovery on the wounded skin. The major population of burn accident is among children and teenager. The scar in this population should be carefully treated not only to prevent joint contracture or deformity but also to prevent mental or psychological suffering, due to their immatureness yet rapid growth in body size and mind. However, the pressure garment design is usually based on adult data. To meet the requirement of this young population the pressure garment should be modified frequently to adapt their rapid change of body size. The goal of this study is to develop a miniature system for measuring the pressure in small body part such as children's knuckles. The Pico Press® (MICROLAB) which have been used to measure pressure garments in Taiwan is used for comparison. The Pico Press® has the advantages of portability, simple user interface, and direct readout. In addition to portability, simple user interface and direct readout, our design can measure any small part such as a children’s knuckle. Further, the pressure measurement of our device possess wider bandwidth that is helpful for dynamic measurement of pressure change during motion or rehabilitation exercise. Moreover, an analog BNC output is provided in our design. This makes future signal processing possible. In addition to the minimization of the sensing element, a wideband recording of the pressure signal is achieved by our device. This device is supplied by 2 popular 9 V batteries and packed in a small case for portability. All the specifications were calibrated and fulfilled the requirements of the initial design goals. This device could be indispensable for the design of more advance pressure garments in the near future. |
