Description

变频式移动体外反搏装置
技术领域：
本实用新型涉及一种体外反搏装置，尤其涉及一种变频式移动体外反搏装置，属于医疗器械技术领域。
背景技术：
缺血性疾病，特别是心脏缺血引起的冠心病，脑缺血引起的中风、瘫痪，对于人类健康的危害性与日俱增。采用体外反搏治疗缺血性疾病，具有不用药物、无创伤性、安全高效等特点，逐渐成为近年来治疗冠心病、脑中风等疾病的常用有效方法之一。随着进入老令化社会，老年痴呆和脑缺血病的加剧以及无创伤性治疗的发展，对体外反搏有进一步的需求。
目前国内外常用的体外反搏装置有固定式和移动式两种。固定式体外反搏装置是由固定在治疗病房的专用反搏床体、控制部分和一个专用泵房组成，全部装置要经过预先安装调试，治疗病人必须在专用床上进行。这对于病人来说很不方便，尤其是对于急性发作的病人来说，不能在抢救室经CT确诊后就及时进行体外反搏治疗，难以取得更快更及时的疗效，因此在一定程度上影响了体外反搏装置的推广使用。移动式体外反搏装置，将反搏装置的主要部件：反搏阀组、泵体、控制计算机等全部集成在一台小车上，可方便地移动到普通病房为病人进行体外反搏治疗，但反搏过程中装置所产生的噪声较大、温升比较明显，进而影响到病人的感觉。
实用新型内容：
本实用新型针对现有技术的上述不足，设计提供一种新型变频式移动体外反搏装置，集成计算机控制、心电遥控接收、变频、散热抗噪等技术，使反搏装置进一步提高各项性能指标。
本实用新型的技术方案中，将体外反搏装置的所有主要部件，包括计算机控制系统、泵体、反搏阀组等集成安装在一台可移动的小车上，在此基础上，通过采用心电遥控技术，变频控制的泵体，解决噪声和散热问题，并进一步提高安全性和疗效。小车的底座上紧凑排列安装了控制箱、泵体和气容立柱，气容立柱的上端安装有可自由活动的悬臂和反搏阀组。本实用新型采用心电无线遥控技术，由计算机控制反搏阀组的工作状态，变频控制的泵体加装消声装置。计算机控制、心电遥控接收及变频器等均安装在控制箱内。反搏阀组下的快速接口经软塑管与预先包在患者肢体上的气囊袋接通。
本实用新型设计的体外反搏装置可自由移动，有利于在医院各病区内自由推动、车载和进入家庭，患者无论是躺着还是坐着，在任何位置上，通过小车的移动、悬臂的上下左右调节，使反搏阀组贴近患者腹部，再经反搏阀组下的快速接口、软塑管和预先包在患者肢体上的气囊袋接通，即可对病人实施体外反搏。
本实用新型采用变频器控制驱动反搏装置的泵体，以保证用多少气供多少气，使泵的工作处在最佳状态，并大大降低功耗和原始噪声。气泵、反搏阀组装在一台小车上，保证其间的最短距离，从而大大减少了管道传输的压差损失。心电的无线遥控接入，做到了患者和装置之间无任何金属连线，不存在漏电流之虑，并进一步提高安全性和疗效。
附图说明：
以下结合附图对本实用新型的技术方案作详细描述。
图1为本实用新型的结构示意图。
如图所示，整个治疗装置为一台可移动的小台车，在治疗装置的底座上排列安装了控制箱1、泵体2和气容立柱，气容立柱的上端安装有可自由活动的悬臂4和反搏阀组3，计算机控制、心电遥控接收及变频器等均安装在控制箱1内，治疗装置底座下的万向轮使小车可方便随意地移动。
图2为本实用新型的控制系统框图及其工作状态示意图。
如图所示，心电发送装置与病人身体连接，心电遥控装置的输出连接计算机的输入端，计算机的输出分别与反搏阀组及变频控制器连接，变频控制器的输出连接泵体，泵体的输出经消声装置连接到反搏阀组。
工作时，心电发射装置发送病人的心电信号，由心电遥控接收装置将接收到的心电信号传送到计算机，控制反搏阀组的工作状态。同时，计算机通过变频器控制装有消声装置的泵体启动关闭，进而控制向反搏阀组提供的供气量。反搏阀组的快速接口经软塑管与预先包在患者肢体上的气囊袋接通。。
本实用新型的实施例中，变频器型号为TD1000，心电遥控接收器型号为DTY-104。
