Abstract

发明专利的名称：抗磁阀。技术领域：医疗器械、潜水、航空、航天。所要解决的技术问题：以往对肌体缺氧病人在进行磁共振检查时，只能依靠氧气袋供氧，而氧气袋需要人按压，而且氧流量小且不易控制。用抗磁阀制成的医用供氧器，因不会对磁共振设备造成影响，而且可以根据病人需要调节氧流量，氧气自动稳定输出。次抗磁阀还可以与抗磁呼吸机配套，使不能自主呼吸的病人得以方便使用磁共振设备检查。抗磁阀还可用于潜水或救生设备，避免铁磁物质阀对仪表、指南针等设备造成影响。

Description

抗磁阀
一、技术领域：
医疗器械、潜水、航空、航天。
二、背景技术
一些病人，由于自主呼吸障碍或者是机体对氧气利用率降低，就需要为病 人吸氧，如果疾病较重，就可能时时刻刻离不开人为增加的氧气。当这样的病 人需要进行核磁共振检查或者是进行其他在强磁场环境下检查时，如果使用普 通供氧装置对病人进行供氧，就可能因为强磁场引起铁磁性物质受力运动而发 生事故。所以磁共振室都有避免推车、氧气瓶等金属物质进入的提示，但由于 疏忽等多种原因，在国内外都发生了不少因磁力吸引铁磁性物质造成人员伤亡、 设备损坏的案例。以往，为避免因铁磁性物质在强磁场环境下引起人员或设备 损害，吸氧时就用普通氧气袋，而氧气袋一方面需要一个人进行按压增加压力 使之流出氧气，另一方面输出流量小，对一些病情重一些的患者，氧流量不足，可以造成检查时肌体缺氧。
为满足磁共振室极其它强磁场环境对病人的供氧，避免铁磁性物质在强磁 场环境发生事故，发明了抗磁阀。抗磁阀采用非铁磁性物质制造，含铁磁性物 质非常少，在强磁场环境中没有明显的被磁化作用，因此避免了强磁场因磁引 力引起的事故发生，也避免铁磁性物质对核磁共振图像造成干扰。该抗磁阀可 以设计不同的输入输出接口，与相关零部件一起制成抗磁医用供氧器或抗磁呼 吸机。抗磁医用供氧器和抗磁呼吸机都可用于强磁环境对病人实施供氧，满足 了对病人在强磁场环境下的供氧需求。
抗磁阀可用于潜水或救生设备，避免铁磁物质阀对仪表、指南针等设备造
三、发明内容
用非金属材料和抗磁金属材料制作阀。
四、附图说明
图1是抗磁阀的基本结构。1与气瓶连接，通过开关手轮3控制气瓶气体是否输出；通 过活塞结构稳压器(或膜片结构稳压器)对气体压力进行降压和稳压，然后通过出气嘴7输 出。输出大小可通过流量调整手轮6进行调整。图中零件选用非金属材料或抗磁金属材料制 成，使抗磁性能符合使用要求。

Claims (1)

1.抗磁阀主要特征是：
1.阀的零部件，采用非金属材料和抗磁金属材料制成，因而阀不会明显被磁化。
2.抗磁阀可以是开关阀或带有减压、稳压功能的阀。稳压系统可采用活塞式或膜片式。
3.主要用于核磁共振室、潜水、航空、航天等对设备周围磁场环境要求高的场合。
