Abstract

本发明的一种含有富勒烯的医用手术石膏衬垫，在与皮肤接触的一侧设有包括含有富勒烯及衍生物的无纺布层。当使用衬垫时，无纺布层与人体皮肤表面进行接触，此时富勒烯涂层与人体皮肤表面进行密切接触，富勒烯及衍生物疏水表面很容易与微生物细胞膜脂相互作用并能够插入膜内，诱导细胞膜损伤，并与细胞内生物大分子相互作用，表现出优异的抗菌、抗病毒活性，可以对皮肤表面进行有效的杀菌抗病毒作用，可以防止患处在包裹石膏的时间由于不清洁带来的细菌滋生的情况。

Description

一种含有富勒烯的医用手术石膏衬垫
技术领域
本发明属于医疗器械技术领域，具体来说是一种含有富勒烯的医用手术石膏衬垫。
背景技术
医用手术石膏衬垫一般用于预防因石膏压迫可能导致的压疮、缺血性挛缩、溃烂和感染等症状；避免因石膏更换不及时造成骨折重新移位的可能；表面多空状的设计，增加了对皮肤的透气性，增加了患者的舒适感。避免二次或多次更换石膏，既减轻了患者的痛苦也减少了治疗费用；减轻了患者复查时医生的劳动强度。
然而现有的医用手术石膏衬垫难以对石膏进行有效支撑，且石膏在固化过程中会散发热量，难以对热量进行隔离。同时，医用手术石膏衬垫在与皮肤接触时，难以对皮肤表面保持干燥卫生和进行灭菌。
发明内容
1.发明要解决的技术问题
本发明的目的在于解决医用手术石膏衬垫与皮肤接触时，难以对皮肤表面保持干燥卫生和进行灭菌问题。
2.技术方案

优选的，还包括依次设置的隔热层、弹性支撑层、过滤层、吸水层和无纺布层，所述无纺布层远离吸水层的一侧为富勒烯涂层，该富勒烯涂层为含有富勒烯及衍生物的无纺布层。
优选的，所述富勒烯涂层为浸渍或喷涂有质量分数为0.1％～10％富勒烯及衍生物悬液的无纺布，所述富勒烯及衍生物为C60及其衍生物或C70及其衍生物中的至少一种。
优选的，所述弹性支撑层、过滤层、吸水层内设有充气支撑机构。
优选的，所述弹性支撑层为海绵层，所述弹性支撑层内设有半圆形的弹性凸起和空心柱，所述弹性凸起和空心柱在宽度方向上的截面为半圆形截面和圆形截面，所述半圆形截面和圆形截面同心。
优选的，所述过滤层内设有活性炭填充物，所述吸水层为吸水棉。
优选的，所述充气支撑机构包括相互连通的中段气囊、末段气囊、前段气囊，所述末段气囊和前段气囊相互平行设置，所述中段气囊两端分别连通于末段气囊和前段气囊的中端，所述中段气囊的长度方向与末段气囊的长度方向相互垂直。
优选的，所述充气支撑机构设有若干个，沿着衬垫的宽度方向上设有裁剪缝，该裁剪缝设置于相邻的充气支撑机构之间。
优选的，所述前段气囊的一侧设有进气嘴，所述进气嘴通过单向气阀与前段气囊连通，所述中段气囊、末段气囊、前段气囊外侧均包裹有密封层。

为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述，附图中给出了本发明的若干实施例，但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例，相反地，提供这些实施例的目的是使对本发明的公开内容更加透彻全面。
需要说明的是，当元件被称为“固设于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件；当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件；本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同；本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明；本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
实施例1
参照附图1-附图3，本实施例的一种含有富勒烯的医用手术石膏衬垫，在与皮肤接触的一侧设有包括含有富勒烯及衍生物的无纺布层。还包括依次设置的隔热层100、弹性支撑层200、过滤层300、吸水层400和无纺布层500，无纺布层500远离吸水层400的一侧为富勒烯涂层600，所述无纺布层500远离吸水层400的一侧为富勒烯涂层600，该富勒烯涂层600为含有富勒烯及衍生物的无纺布。所述富勒烯涂层600为浸渍或喷涂有质量分数为0.1％～10％富勒烯及衍生物悬液的无纺布。当使用本实施例的衬垫时，无纺布层500与人体皮肤表面进行接触，此时富勒烯涂层600与人体皮肤表面进行密切接触，富勒烯及衍生物疏水表面很容易与微生物细胞膜脂相互作用并能够插入膜内，诱导细胞膜损伤，并与细胞内生物大分子相互作用，表现出优异的抗菌、抗病毒活性，可以对皮肤表面进行有效的杀菌抗病毒作用，可以防止患处在包裹石膏的时间由于不清洁带来的细菌滋生的情况。
本实施例的富勒烯及衍生物为C60及其衍生物或C70及其衍生物中的至少一种。
本实施例的过滤层300内设有活性炭填充物，活性炭填充物可以对衬垫使用期间接触的杂质进行过滤，防止杂质污染患处。吸水层400为吸水棉，可以对衬垫使用期间接触的水分和人体皮肤表面排出的水分进行良好吸收，保证患处干燥。
本实施例的弹性支撑层200为海绵层，弹性支撑层200内设有半圆形的弹性凸起220和空心柱210，弹性凸起220和空心柱210在宽度方向上的截面为半圆形截面和圆形截面，半圆形截面和圆形截面同心。
本实施例的弹性支撑层200、过滤层300、吸水层400内设有充气支撑机构700。充气支撑机构700包括相互连通的中段气囊710、末段气囊720、前段气囊730，末段气囊720和前段气囊730相互平行设置，中段气囊710两端分别连通于末段气囊720和前段气囊730的中端，中段气囊710的长度方向与末段气囊720的长度方向相互垂直。中段气囊710、末段气囊720、前段气囊730构成工字型支撑，可以有效的对衬垫进行支撑，空心柱210的长度方向和末段气囊720的长度方向相互垂直，可以组成支撑网络，进一步提高衬垫的支撑性能。
本实施例的充气支撑机构700设有若干个，沿着衬垫的宽度方向上设有裁剪缝760，该裁剪缝760设置于相邻的充气支撑机构700之间。可以便于衬垫的裁剪使用。前段气囊730的一侧设有进气嘴740，进气嘴740通过单向气阀750与前段气囊730连通。通过进气嘴740对充气支撑机构700进行充气，单向气阀750可以防止充气支撑机构700从进气嘴740处漏气。
本实施例的中段气囊710、末段气囊720、前段气囊730外侧均包裹有密封层770，密封层770对中段气囊710、末段气囊720、前段气囊730进行二次密封，防止中段气囊710、末段气囊720、前段气囊730破损带来的漏气而影响使用安全性。
本实施例的隔热层100远离弹性支撑层200的一侧设有防水膜110，防水膜110防止石膏在固化的过程中有水分渗入衬垫，影响衬垫使用。
以上所述实施例仅表达了本发明的某种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制；应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，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；因此，本发明专利的保护范围应以所附权利要求为准。
