Abstract
一种智能输注工作站，包括：壳体（1）、多个输注泵（2）和控制系统（3），输注泵（2）可拆卸地安装在壳体（1）上，多个输注泵（2）均与控制系统（3）通信连接。控制系统（3）用于在相邻的两个输注泵（2）为中继切换输液时，控制两个输注泵（2）按照预设的速度逐步变化，以实现平滑中继切换。智能输注工作站能够在中继输液切换的过程中，使得输注速度匀速变化，实现平滑中继切换。
Description
本发明涉及医疗输液技术领域，特别涉及一种智能输注工作站。
一般，输注工作站包括模块化安装的输注泵(输液泵和/或注射泵)和控制系统。根据应用需要，输注泵可以全部都是输液泵，也可以全部都是注射泵，也可以部分输液泵部分注液泵。控制系统包括嵌入式系统，能通过CAN数据接口与各输注泵通讯链接，实现各输注泵泵状态数据采集及下发控制参数给各泵，工作站还能通过WIFI通讯接口与医院HIS(医院信息系统)和/或CIS(临床信息系统)等系统连接，将输注泵产生的输注数据上报给HIS和/或CIS。控制参数可包括KVO速度(keep vessel open：保持静脉开放)、注射速度、输液精度和输液速度等。输注泵在完成输液任务后自动按照一个很低的流速输液，防止回血而阻塞针头。
对于一次输入剂量较多的药液，一般采用中继输液来完成。中继输液是指两台以上的输注泵相互配合，按照预设的输液顺序依次进行输液，前面一台输注泵输完，后面一台输注泵接着输，中间不需要护士操作。现有的中继输液方案是，前一台输注泵停止输液后，然后再启动后一台输注泵，这种输液方式会产生中间可能有一个比较短的时间是断开的不连续的输液即输注泵的启动延时的问题，这会导致一些误差，让患者的治疗过程可能存在因设备的原因产生治疗药物浓度(尤其是半衰期短)的突变，这将会影响对患者的治疗。
目前的一种解决思路是优化输注泵的启动机构，将启动时间控制在毫秒级别，但这种处理方式会提高输出泵的制造成本。
因此，亟待需要提供一种能够让患者的治疗过程不存在因设备的原因产生治疗药物浓度的突变的中继输液方法。
