Description

一种具有自动报警装置的可折叠麻醉机 技术领域
本发明涉及一种具有自动报警装置的可折叠麻醉机，属于医疗器械领域。
背景技术
医院在给病人做手术进行麻醉的时候，大多数是使用一次性的注射器多次穿刺进行麻醉，不仅操作起来非常麻烦，费时费力，麻醉药物扩散慢，严重影响手术进度，给医务人员增加了工作量，而且，这种注射的针体比较平直，给病人进行麻醉时，对表面组织进行麻醉比较容易，对于某些腔道类的器官则比较困难，给医务人员增加了工作难度和强度，而且达不到预计的麻醉效果，也会增加患者手术的痛苦程度。
一般小型的简单手术，采用点滴法给患者麻醉，但是这种麻醉方式的麻醉深度不容易控制，对呼吸道有刺激作用，麻醉时间也不容易控制，影响手术的进行，对手术后的恢复也带来了诸多不稳定的因素。
麻醉机是目前医院经常用到的设备，是通过机械回路将麻醉药送入患者的肺泡，形成麻醉药气体分压，弥散到血液后，对中枢神经系统直接发生抑制作用，从而产生全身麻醉的效果。不仅能适用于对患者进行全身麻醉，而且患者在麻醉过程中失去意识的时候能辅助患者的呼吸从而保证其生命安全，还能复合使用其他麻醉药物，以不同形式做复合麻醉，是一种能将麻醉和非麻醉气体提供给病人使用的医疗设备。
在进行麻醉的过程中，由于设备中设置有多个流量计，用于监测麻醉的进行状况，以保证患者的安全，但是医务人员必须要同时监测多个流量计的变化，并且与安全值进行比对，防止出现事故，这样就增加了医务人员的工作难度，有时还会造成监测不及时出现问题，安全性低。另外传统的麻醉机整个机体较 大，显示屏和麻醉呼吸装置会突出在机架的外面，不方便移动和放置。
发明内容
本发明要解决的技术问题是：为了克服现有技术的不足，提供一种具有自动报警装置的可折叠麻醉机。

氧气供气装置的出口处、氧化亚氮供气装置的出口处、麻醉蒸发罐的出口处、呼吸机的出口处和二氧化碳吸收瓶的入口处的流量计接入信号采集电路中，通过信号处理电路传递到控制器单片机中，单片机将信号进一步处理，反馈到报警电路中，当流量计的流量处于非正常状态，报警电路将启动报警器7和报警显示灯组6，针对每一个流量计均设置有单独的报警显示灯，便于医务人员针对性的查看回路的问题，并及时的调整。
显示屏5用于监测患者的各种生命特征参数，以保证手术的进行，提高安全性。由于麻醉呼吸装置和显示屏5均是铰接在机架1上，在移动机器或者不使用的时候便可以将麻醉呼吸装置折叠放置在置物箱3内，将显示屏5折叠放置在报警装置的前面，节省空间，降低机器的损坏率。
与现有技术相比，该具有自动报警装置的可折叠麻醉机通过控制系统和报警装置可以准确的针对每一个流量计进行报警监控，减少了医务人员的工作量和工作难度，提高麻醉的安全性，由于麻醉呼吸装置和显示器均是铰接在机架上，在不使用的过程中，便于把它们折叠起来，便于放置和移动，降低机器的损坏率，节省空间。
