Abstract

本发明涉及一种医用可吸收防粘连薄膜，包括由易被人体吸收材料制成的膜本体，所述膜本体上均匀排列设置有若干个孔，孔的孔径为0.01～0.02um，相邻孔之间的间距为0.1～0.15um。该薄膜不易受损，在其使用时，伤口不会被完全覆盖，伤口处透气性较好，有利于伤口的愈合。

Description

医用可吸收防粘连薄膜
技术领域
本发明涉及到医疗用品领域，特别是指一种医用可吸收防粘连薄膜。
背景技术
医用可吸收防粘连薄膜的材料通常为聚乳酸，聚乳酸(PLA)是一种无毒无刺激性的高分子材料，具有优异的生物相容性、生物可吸收性及较高的机械强度和可加工性，日渐成为重要的医用高分子材料，在临床上具有广泛的发展前景。作为一种重要的可生物降解高分子材料，已获得美国FDA的认可，目前聚乳酸及其共聚物在许多医学领域得到了应用，如：骨固定材料、外科手术缝合线、外科手术防粘连膜、细胞膜构建结构物、人工韧带或肌腱、人工血管、组织工程支架材料、药物释放系统、眼科植入材料、医用辅料等。
目前所使用的医用可吸收防粘连薄膜，通常为一张完整的薄膜，由于其材料本身的特性，所以该薄膜在常温下较硬较脆，容易受损；另外，在使用时，其将伤口完全覆盖，使得伤口处透气性较差，不利于伤口的愈合。
发明内容
本发明所要解决的技术问题是：提供一种不易受损、并且有利于伤口愈合的医用可吸收防粘连薄膜。
为解决上述问题，本发明采用的技术方案是：医用可吸收防粘连薄膜，包括由易被人体吸收材料制成的膜本体，所述膜本体上均匀排列设置有若干个孔，孔的孔径为0.01～0.02um，相邻孔之间的间距为0.1～0.15um。
所述的孔为大小相同的圆孔。
本发明的有益效果是：上述的医用可吸收防粘连薄膜，通过在其上设置若干个孔，孔的孔径为0.01～0.02um，相邻孔之间的间距为0.1～0.15um，该尺寸既不会影响膜的使用效果，也不会影响膜的强度，并且由于孔具有可变型性，从而增加了该薄膜的柔韧性，从而使得该薄膜不易受损，另外由于孔的存在，在其使用时，伤口不会被完全覆盖，伤口处透气性较好，有利于伤口的愈合。
附图说明
图1是本发明的结构示意图；
图中：1、膜本体，2、孔。
具体实施方式
下面通过具体实施例对本发明医用可吸收防粘连薄膜作进一步的详细描述。
如图1所示，医用可吸收防粘连薄膜，包括由易被人体吸收材料制成的膜本体1，所述膜本体1上均匀排列设置有若干个孔2，孔2的孔径为0.01～0.02um，相邻孔2之间的间距为0.1～0.15um。
作为优选方案，所述的孔2为大小相同的圆孔。从而使得孔2的可变形量达到最大化。
本发明的有益效果是：上述的医用可吸收防粘连薄膜，通过在其上设置若干个孔2，孔2的孔径为0.01～0.02um，相邻孔2之间的间距为0.1～0.15um，该尺寸既不会影响膜的使用效果，也不会影响膜的强度，并且由于孔2具有可变型性，从而增加了该薄膜的柔韧性，从而使得该薄膜不易受损，另外由于孔2的存在，在其使用时，伤口不会被完全覆盖，伤口处透气性较好，有利于伤口的愈合。
上述的实施例仅例示性说明本发明创造的原理及其功效，以及部分运用的实施例，而非用于限制本发明；应当指出，对于本领域的普通技术人员来说，在不脱离本发明创造构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。

Claims (2)
