国内医疗企业推出无PVC蠕动泵管

邻苯二甲酸二辛酯(2-乙基己)(简称DEHP)是一种用于软化PVC的化学物质,它会危害人类健康吗?虽然科学界对此争议目前尚无定论,但是,公众却已经表明了反对DEHP、反对PVC的立场。济南医用硅橡胶制品厂(www.jn-siliconerubber.com)在这其中发现了巨大的商机。

济南医用硅橡胶制品厂建于1978年,据称是中国首家专业生产医用聚合物产品的企业。2005年改组为私营企业后,更加重视技术研发,加大了产品创新投入。

蠕动泵管通常采用PVC材料制造,但除了健康上的疑虑以外(DEHP可能会侵入人体),还有一些性能缺陷,例如:回弹力低、使用后容易变形。济南医用硅橡胶厂的总经理葛正礼先生了解到高端非PVC管蠕动泵设备的最佳商机已经到来。因此,他们开始不断地寻找性质合适的材料、以及具有相关技术的供应商。

起初,公司测试了各种普通硅树脂材料,希望替代PVC,但试验结果均不理想。葛经理认为主要的问题是这些材料的泵管回弹力低、压缩变形大。最后,他找到GE高新材料集团的子公司-GE东芝有机硅公司(上海; www.gesilicones.com)生产的Tufel III硅树脂弹性体,其中的Tufel III 92506具备了各种合适的性质。

Tuffel III材料由两种成分构成,是一种铂金固化硅树脂弹性体,具有挥发性低、回弹力高的的特点。 这种具生物相容性的材料压缩变形小,无需二次固化。济南医用硅橡胶厂对其进行了严格的检验测试,结果表明该材料十分适合所需应用。

葛经理说:“与其他铂金体系硅橡胶管比较,Tufel III制成的管件使用寿命更长。试验显示,在1000-1200转/分的情况下,Tufel III制成的管件使用寿命达几百小时。”此外,此硅树脂弹性体回弹力为72%,且压缩形变率仅为10%。

葛经理表示,该蠕动泵自从去年3月投放中国医疗市场以来,备受欢迎。该厂目前有30%的订单来自国外,包括呼吸机及麻醉机专用硅橡胶波纹管、硅橡胶引流管、硅橡胶医用导管等等。无PVC蠕动泵管的研发成功将使其成为业内更具竞争力的企业。
