下面结合附图,对本申请的一些实施方式作详细说明。在不冲突的情况下,下述的实施例及实施例中的特征可以相互组合。
本申请的麻醉机属于医疗器械技术领域,麻醉机是手术室最常用的设备之一,主要在手术过程中对病人的意识水平、痛觉水平进行调节的医疗设备。
一般情况,麻醉机包括供气部分、控制部分、麻醉通气回路部分、废气排放部分及麻醉蒸发器等,其中,控制部分包括控制面板、电源输入模块、辅助输出模块、气体压力检测模块、麻醉蒸发器控制模块、插件模块、AGSS模块及 显示模块等,这些电子模块在在麻醉机运行过程中会产生热量,当热量累积过多容易引起电子或气路的部件失效,甚至引发火灾等风险。
目前,麻醉机通常会在热量聚集的部位设置散热孔及散热风扇,将麻醉机内部的热量强制吹出,并引入冷空气,从而使麻醉机内的各元器件能够在其规定的温度范围内正常工作。但是,散热风扇不仅有失效的缝隙,同时在运行过程中容易会产生噪音,给手术室环境带来不利。
如图1至图5所示,本申请提供了一种麻醉机,包括主机机箱10、显示装置20、麻醉蒸发器30、麻醉通气回路、主控板60、电源接口80以及气源接口90,其中,气源接口90和电源接口80均设置于主机机箱10上,麻醉蒸发器30与主机机箱10可拆卸连接,气源接口90与麻醉通气回路连接,并且至少部分麻醉通气回路设置于主机机箱10内。在本实施方式中,显示装置20包括显示设备21和用于固定显示设备21的显示壳体22,主控板60设置于显示壳体22上,且主控板60与电源接口80及显示设备21电性连接。
采用以上技术方案后,由于麻醉机在运行过程中,麻醉机内部各元器件的发热量不同,例如主控板60属于自身发热量大的元器件,而麻醉通气回路上的控制阀等属于发热量小或不发热的元器件,当主控板60和麻醉通气回路等元器件集成在主机机箱10内,主控板60和麻醉通气回路等元器件之间会产生干扰,放热量大的元器件就会影响发热量小或不发热的元器件,进而使发热量小或不发热的元器件的使用寿命缩短。而本申请将发热量大的主控板60设置在显示壳体22上,不仅可以避免主控板60工作时产生的热量影响到主机机箱10内各元器件的工作,确保主机机箱10内各元器件能够在一个安全工作温度下工作;而且也有利主控板60的散热,为主控板60提供充足的散热空间,确保主控板60能够通过显示壳体22向周围散热。
在一个可选的实施方式中,主控板60可以设置于显示壳体22的内侧,主控板60也可以设置于显示壳体22的外侧,其中,当主控板60设置于显示壳体22的外侧时,主控板60可以安装在盒子中而后将盒子固定在显示壳体22的外侧,盒子的形状及大小可以与显示壳体22的形状及大小相匹配,以确保麻醉机外部的结构形状。同时显示壳体22的外侧也可以设置一个凹槽,用于放置主控板60,然后盖上相应的盖子对主控板60进行保护等等,其目的主要为了将主控板60设置于显示壳体22上,至于采用什么方式进行固定,本申请并不限制。
在一个可选的实施方式中,麻醉机上设有散热结构,散热结构安装在显示壳体22上,且散热结构的位置与主控板60的位置相对应,以使得主控板60在工作时产生的热量能够通过散热结构快速扩散到空气中,起到降温效果。
具体的,散热结构可以包括设置在显示壳体22的进气孔和出气孔,进气孔与出气孔连通形成冷却风道,该冷却风道流经主控板60的外表面,在麻醉机工作时,主控板60因工作产生的热量能够通过冷却风道上的气流释放到空气中,确保主控板60能够在规定的温度下工作,延长主控板60的使用寿命。
其中,为了提高显示壳体22的降温散热效率,显示壳体22上还可以设置微型散热风扇,通过散热风扇能够加速显示壳体22内热空气的排出,同时也不会增加麻醉机的噪音,给手术室环境带来不利。
此外,散热结构还可以包括散热片,散热片紧贴主控板60上,能够最大程度地增加主控板60的散热面积,使主控板60上的电子元件充分散热。其中,散热片可以采用铝合金材质的散热鳍片,其大小及形状可以与主控板60的大小及形状,能够有效增加散热结构的散热效果。
在一个可选的实施方式中,散热结构包括导热垫,导热垫的一端抵接在主控板60上,导热垫的另一端抵接显示壳体22上,以使得主控板60工作时产生的热量能够通过导热垫传递至显示壳体22,再通过显示壳体22扩散到空气中;或者显示壳体22内侧设有金属框,导热垫与金属框连接并通过金属框将主控板60工作时产生的热量扩散到空气中等等。
采用以上技术方案后,由于显示壳体22上设置有散热结构,因此,散热结构能够将主控板60工作时产生的热量扩散到空气中,能够将显示壳体22内部的热量排送到外部的空气中,使得主控板60的散热效果更明显,确保了主控板60能够在其规定的温度下工作,提高了主控板60的使用寿命。
