Description

一种医疗健康可穿戴设备防滑、防脱表面层结构
技术领域
本发明涉及一种防滑表面,更确切的说是一种新型可用于医疗可穿戴设备上的防滑、防脱表面,能够有效解决可穿戴设备与皮肤接触不紧密,容易打滑脱落的问题。
背景技术
随着医疗健康技术的发展,人们对健康要求的提高,各种生理健康信号检测传感器也应运而生,如穿戴式心率检测装置、血压监测仪以及动态心电图等。这些传感器通常直接长时间佩戴在人体表面,从而获取实时准确的生理信息,这就需要穿戴设备能够舒适稳定的固定于人体皮肤表面。对截肢者而言,假肢能够为他们恢复一定的生活自理和工作能力,其设计要求能够具备可靠的固定,舒适的穿戴。
在传统医疗健康可穿戴装置的使用中,通常通过人体皮肤直接将装置固定上。由于人体皮肤柔软,固定时需要大力夹紧才能防止脱落,这容易导致血流不通,影响穿戴的舒适程度。此外,过紧的夹持力以及人体持续运动使得汗液分泌,容易导致打滑脱落,影响使用的安全和体验。
本专利通过本专利通过对树蛙在潮湿环境中超强爬附能力的仿生研究,提出一种新型的医疗健康装置防滑防脱表面,其能够有效的增加器械与人皮肤之间的摩擦,即时在潮湿皮肤表面依然能够稳定固持,从而增加器械、设备的可靠性。
发明内容
1、目的:本发明设计一种新型防滑表面用于医疗可穿戴设备上,能够有效解决传统可穿戴设备与皮肤接触不紧密,容易滑脱的问题。
2、技术方案:本发明是一种医疗健康可穿戴设备防滑、防脱表面层结构,是由单元结构和表面层共同组成表面层结构;该单元结构按一定间隔密排于表面层上,从而形成相互连通的沟槽,通过这些连通沟槽,皮肤表面汗液能够排入沟槽,增大表面与皮肤接触面积,进而提高医疗可穿戴设备的装夹稳定性。
所述单元结构的形状为多边棱柱形或者圆柱形;该单元结构如果为多边棱柱形,则可选三棱柱、四棱柱或六棱柱形等,其高度(亦即厚度)为1μm至1mm之间,尺寸大小为外接圆直径1μm至2mm之间;该单元结构如果为圆柱形,其高度(亦即厚度)为1μm至1mm之间,直径为1μm至2mm之间;
该单元结构的材料为金属材质或者橡胶类高聚物材质;
所述表面层为现有医疗健康设备的表面层,也可以按照实际需要另行设计;该表面层另行设计时,其厚度与尺寸大小按实际需要裁制;
该表面层材料为金属材质或者橡胶类高聚物材质;
其中,该单元结构与表面层两者相结合的方式可通过胶粘、化学刻蚀或直接在表面层上压印得到。
3、优点及功效:相对于传统表面,密排六棱柱表面由树蛙脚掌湿环境摩擦仿生而来,其能够在人皮肤软、湿环境下能提供充足的摩擦力,从而减小固定所需要的压力,降低由此带来的血液流通不畅,肢体发麻,影响使用体验的问题。此外,由于设备与皮肤直接接触,导致皮肤表面汗液堆积,降低设备稳定性,而防树蛙脚掌表面能够在潮湿环境下提供充足的摩擦力,从而提高设备稳稳定性。

具体实施方式
通过仿生树蛙脚掌表面密排棱柱结构(图1),设计制作出了防滑、防脱表面层结构。下面将结合附图和实施例对本发明做进一步的详细说明。
第一实施例(1,图2)为人假上肢的防滑、防脱表面层结构(11,图3),单元结构为六棱柱(111)橡胶材质,其高度(亦即厚度)为30μm,外接圆直径为120μm,表面层为橡胶材质,大小覆盖整个与皮肤接触面积。通过将橡胶表面加热压印单元结构,获得表面层结构。
第二实施例(2,图4)为人假下肢的防滑、防脱表面层结构(21,图5),单元结构为变形六棱柱(211)橡胶材质,其高度(亦即厚度)为60μm,外接圆直径为200μm,表面层为橡胶材质,大小覆盖整个与皮肤接触面积。通过在模具浇铸复制,获得表面层结构。
第三实施例(3,图6,7)为可穿戴心率带的防滑、防脱表面层结构(31,图8),单元结构为六棱柱(311)橡胶材质,其高度(亦即厚度)为10μm,外接圆直径为300μm,表面层为橡胶材质,大小覆盖整个与皮肤接触面积。通过将微六棱柱单元结构粘接于表面层上,接获得表面层结构。
第四实施例(4,图9)为可测心率手表的防滑、防脱表面层结构(41),单元结构为六棱柱金属材质,其高度(亦即厚度)为5μm,外接圆直径为500μm,表面层为金属材质,大小覆盖整个与皮肤接触面积。通过在表面层上化学刻蚀出单元结构得到表面层结构。
其它结构类型包括三棱柱表面层结构(51,图10),圆柱表面层结构(61,图11),四棱柱表面层结构(71,图12)。通过以上表面层结构,可以达到可穿戴设备防滑、防脱的效果,从而提高可穿戴设备的可靠性和舒适性。
