The Antiperspirative Effect of the Silicon Socket：A Qualitative Study
矽膠套筒抗流汗效應之定性研究
摘要
傳統的義肢套筒及內套是由聚乙醚，聚乙烯，聚丙烯或特製海綿 （pelite） 等材料做成的，當患者穿戴著這些傳統義肢在走路或操作日常生活時，常常會因流汗而使殘肢味道難聞，但最近發明的以矽膠為內套之矽膠吸入型套筒 （silicon suction socket） ，則反而可以減少殘肢的流汗。究竟是什麼因素使矽膠減少患者殘肢皮膚之流汗？是矽膠本身的化學特性使然，抑或是矽膠所產生之機械效應引起的？因此，本研究乃針對上述問題，找來二十位健康受試者，其中男性9位與女性11位，年齡從10歲到72歲，平均37±8.4歲。每位受試者的前臂都要塗上甘油碘酒 （2：1）混合液，然後分梯次用3M膠布貼上下列物質 （每種物質的大小都是2×2×0.3cm 的薄方塊）：（1）第一梯次：右前臂矽膠方塊，左前臂特製海綿方塊；（2）第二梯次：右前臂聚乙烯方塊，左前臂橡膠方塊；（3）第三梯次：右側平面矽膠方塊，左側凹凸面矽膠方塊；（4）第四梯次：右側平面聚乙烯方塊，左側凹凸面聚乙烯方塊。然後要受試者慢跑十到二十分鐘直到流汗為止。接著取下上述物質，將澱粉平均灑在前臂上，立即觀察顏色變化情形，並拍照存證。 實驗結果顯示不但貼矽膠方塊的皮膚流汗減少，更令人意外的是連貼特製海綿、聚乙烯及橡膠的部份也會減少流汗。此外，平面方塊的止流汗效應遠比凹凸不平面方塊之止流汗效應為佳，因此吾人的結論是止流汗效應與物質的物性無關，而與上述物質經緊密黏貼之後所產生的機械效應有關。 而臨床上為何只有矽膠製成的義肢套筒才有止汗效果呢？主要是因為矽膠製成之內套可與皮膚產生完全密合的機械效應，而其它物質如特製海綿、聚乙烯或聚丙烯等，則在實際的日常環境裡沒有辦法與皮膚維持無時無刻密合的效果，因此無法有效地阻止流汗。本研究的缺點則是沒有使用定量方法來測流汗的程度，而僅使用定性的碘酒澱粉反應，此乃是後續研究極需要改進的地方。

In clinical prosthetic experience, profuse sweating was a major problem when conventional sockets or inserts were used. However, the newly developed silicon suction socket could prevent that. We doubted that these differences came from the different nature of the silicon, pelite and polyethylene. So using the starch iodine sweating test, the forearm skins of the twenty normal subjects were sealed with a piece of 2cm×2cm×0.3cm silicon, pelite or polyethylene respectively. Surprisingly, not only silicon but also pelite and polyethylene could inhibit sweating. This meant that decreased sweating of the silicon suction socket might not be due to the chemical property of the silicon, instead, due to the little amout of the dead space between the silicon socket and skin. In other word, the more intimate sealing existed between the socket and skin, the less sweating. This was the reason why conventional inserts, made of pelite or polyethylene, could not prevent sweating clinically though, they did decrease sweating under the experimental intimate sealed situations. In addition, the quantitative sweating test will be applied in the further related studies because the starch iodine sweating test is qualitative only.
