Abstract

一次性医用气垫密封口罩是一种橡塑制品,属医疗器材。本实用新型采用有凸楔5的外压环4和有凹槽3的内压环2与胶泡9制得气垫1,硬面盘6喇叭状环缘上压制有接口槽7,经粘合硬面盘6与气垫1制得气垫密封口罩。其结构简单可靠,成本低廉,在医疗中可达一次性使用程度。

Description

医用气垫密封口罩,是一种橡塑制品,属于医疗器材行业。
在治疗过程中,为使需要输氧或者需要强迫呼吸的病人,特别是危急病人获得足够的氧气,通常都用专用的口罩。口罩与面部的接触必须既紧密贴合又舒适,又不致于使空气从口罩和面部接触的贴合处泄漏、逃逸。
现有的医用口罩不论是用橡胶制作成气垫,还是用硅胶或塑料制成软垫,它们的制造工艺所造成的成本,使这些产品的价格非一次性使用所能承受。近年来美国Respironics公司推出一次性医用气垫口罩于市场,其制造工艺是以模塑制造气垫(Cushion)和面盘(Faceplate),然后将它们粘合,成为口罩(mask)。如此的制造工艺较前已有长足的进步,但仍有较高的原料消耗,故其销售价格仍然比较贵,还远不能达到中国市场接受的一次性使用的程度。
本发明旨在提供一种新的医用气垫口罩。在结构上气垫以及气垫和面盘结合简单可靠,得以实现生产成本的低廉,达到一次性使用的目的,且其密封性能和舒适效果良好。
下面给出本发明的实施例:
图1  一次性医用气垫密封口罩示意图
图2  气垫的半成品:胶泡的示意图
图3  制气垫用模塑外压环示意图
图4  制气垫用模塑内压环示意图
图5  气垫的示意图
图6  硬面盘的示意图
其中:1.气垫    2.内压环    3.内压环凹槽
4.外压环    5.外压环凸楔    6.硬面盘
7.硬面盘上与压环的接口槽
8.硬面盘上与供气系统接口    9.胶泡
附图中A、B、C、D、E、F分别是各示意图中的局部放大部分。
将气垫的半成品胶泡9予充气至适当程度,下置内压环2上置外压环4,在外压环4上有凸楔5,其弧楔尺寸与内压环2上的凹槽3相配合,内压环2与外压环4的配合间隙应小于胶泡二倍壁厚。当内压环2与外压环4压接后,再切割去内外压环上面胶泡9的多余部份后,就制得气垫1。模塑的硬面盘6其喇叭状环缘压制有可与内外压环相配合的接口槽7,接口槽7的槽深相等于压环的高度,槽宽则相等于压环(内外压环)的厚度,此时,在硬面盘6的接口槽7内壁涂上粘合剂,将气垫1上的压环对准硬面盘6上的接口槽7压紧粘合后,即制得本实用新型发明所述的一次性医用气垫密封口罩。

Claims (1)
