Description

具有超声扫描监测功能的监护设备、超声装置及相应方法 技术领域
本发明涉及医疗设备领域，尤其涉及一种具有超声扫描监测功能的监护设备、超声装置及相应方法。
 背景技术
在急危重症患者的诊断和临床监护中，经常会使用可以监测病人生命体征的监护仪。现有监护仪提供的心脏监测信息，包含有心电监护（ECG或EKG）、血压、血氧饱和度（SPO2）等参数。其中，EKG参数很容易受到干扰，例如电极接触不良、人为操作不当等都可能导致心电测量参数偏离实际情况，从而产生的虚警会导致报警疲劳，影响医生对突发状况处理的及时性。另一方面，血压参数一般以数值型参数出现在监护仪显示界面上，存在不连续的问题，且不能直观的反应心动状态。例如出现低血压时，无法判断出是心衰还是血容量不足。而SPO2参数存在不稳定及不实时的缺陷。
在一些临床场合，例如非心脏的手术中对心脏的监测、转运病人的监测、重症监护（ICU）科室中的监测等，需要长时间监测病人心脏组织运动的实时参数，如对射血分数、左室短轴缩短率等血流动力学参数进行无创监测。另外，还需要在第一时间准确判断病人的心动状态。这类参数不能通过一般的监护仪检测到，需要靠超声诊断系统才能获得。
而传统的超声诊断系统仅设置在超声科室内，其需要医生手持超声探头对病人检查部位进行扫描后获得超声图像，供进行短时间诊断使用。对于上述一些需要对病人各项生理参数（其中包括器官组织的实时信息，如血流动力学参数）进行长时间的监测的临床场合，现有这种超声诊断系统尚不能应用到这类的长时间监护中，很难满足临床更广泛的需求。另外，在现有技术中，对心脏的血流动力学的超声扫描，其探头常采用放置于病人食道的探头，如果长时间采用经食道的探头对病人进行监护，会给病人带来很大的不舒适性。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明一种具有超声扫描监测功能的监护设备的一个实施例的结构示意图；
图2为图1中超声功能模块进行周期性扫描的示意图；
图3为本发明一种用于监护的超声装置的一个实施例的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，是本发明一种具有超声扫描监测功能的监护设备的一个实施例的结构示意图；该具有超声扫描监测功能的监护设备，其包括包含有监护功能模块10及超声功能模块12的监护主机1、监护探头20、超声探头22以及显示设备3，其中：
监护功能模块10，用于监测常规生理参数，常规生理参数包括诸如：ECG参数（心电监护参数）、血压、血氧饱和度参数及呼吸等；具体地，监护功能模块为集成有监测上述至少一种参数的功能模块，具体例如集成有ECG监护的功能、监护血压功能、监护血氧饱和度参数功能及监护呼吸功能等的模块。其中，ECG参数进一步包括诸如心率参数、室性早搏参数等；
超声功能模块12，用于对被测对象在指定时间间隔下进行超声扫描监测，获得被测对象的回波信号并进行处理；其中，超声功能模块对被测对象的回波信号进行处理后得到诸如血流动力学参数及心动参数等，具体地，包括诸如心脏射血分数、左室内短轴缩短率、每搏排血量、心排血量、心脏指数、左室舒张末期容积及左室收缩末期容积中至少一个，其中，超声功能模块12对被测对象的回波信号进行处理可以具体为：根据回波信号进行计算，获得数值型参数、波形或趋势图，数值型参数即为血流动力学参数及心动参数等生理参数信息；在另一个实施例中，超声功能模块12对被测对象的回波信号进行处理可以具体为：超声功能模块可以对回波信号进行数字处理以生成数字处理环节信号，并可选择性的进一步生成所选或者所支持成像模式的超声图像，超声功能模块根据数字处理环节信号或超声功能模块所支持的成像模式获得的超声图像进行自动计算分析，获得数值型参数、波形或趋势图；数字处理环节信号为如下的至少一种：射频信号、基带信号、包络信号；超声功能模块所支持的成像模式为如下的至少一种： B型（Brightness，辉度）成像模式、M型（Motion，一维空间多点运动时序图）成像模式、彩色成像模式、脉冲波（PW）成像模式、弹性成像模式、3D（三维）成像模式及4D（四维）成像模式。
监护探头20耦接于监护功能模块10上，超声探头22耦接于超声功能模块12上；
显示设备3，其耦接于监护主机1上，接收监护功能模块10输出的常规监护生理参数以及超声功能模块12输出的经处理后的回波信号并显示。
具体地，显示设备上进一步设置有：
常规监护信息显示单元30，用于显示监护功能模块10所监测到的常规生理参数；
超声信息显示单元32，用于显示超声功能模块12所获得的经处理后的回波信号。
在一个具体的实施中，通过在显示设备3的显示屏幕上设置不同的显示窗口，来分别显示常规生理参数及经处理后的回波信号（图像、波形或数值型参数）。
进一步的，监护主机1还包括：
存储模块16，用于存储预设时间内监护功能模块10所监测到的常规生理参数和/或 超声功能模块12所获得的经处理后的回波信号，上述存储的常规生理参数及经处理后的回波信号，可以在显示设备3的不同显示窗口上进行回放，供临床诊断参考。
其中，超声探头22为可紧密贴合在被监护者（病人）体表的超声探头，该探头可以长时间地贴合在被测对象（如病人）体表的固定位置上，可以保证每次对被测对象固定位置处的扫描都是在同一切面上，使获得的超声图像更加准确。
另外，在一个实施例中，在超声功能模块12上可连接多个超声探头22，其中每一超声探头22均可紧密贴合在被监护者体表的不同部位，从而便于对被测者的多个部位同时进行超声扫描监测。
在上述的实施例中，超声功能模块12可以与监护功能模块10集成为一体，集成在监护主机1中。可以理解的是，在另外的实施例中，超声功能模块12可以与监护功能模块10为相互独立的模块，例如，超声功能模块12与监护功能模块10均固定连接在一监护主机上；或者，超声功能模块12与监护功能模块10也可以是相互独立的可拆卸的模块，其均与一监护主机实现插拨连接，在该监护主机上相应位置上预留有相对应的插拨接口，当需要使用某个/某些测量模块时，只需将相应的测量模块插接到该监护主机上即可。
可以理解的是，在其他的实施例中，超声功能模块12可独立于监护功能模块10工作，超声功能模块12可作为便携超声设备单独使用。
在一些实施例中，可以对超声功能模块12启动周期以及持续时间进行设置，具体地，监护主机1包括有：
扫描周期设置模块14，用于设置超声功能模块12启动扫描的时间间隔和/或每次扫描的持续时间。当然，扫描周期设置模块14也可以仅用于设置启动扫描的时间间隔或者每次扫描的持续时间。设置上述与扫描相关的时间参数时，可以通过显示设备的触摸屏装置或者键盘、主控板等装置直接输入想要设定的参数，也可以在系统中存储多个备选的配套参数供使用者选择，每一配套的扫描时间参数（包括每次扫描时间和扫描间隔）进一步可以对应预设为某一种应用场景下的默认扫描时间参数，比如根据不同监护对象预设不同类型备选扫描时间参数，医生通过选择不同监护对象即对应选择不同的扫描时间参数。另一方面，这里所说的扫描周期，可以理解为将其设定成固定间隔时间、固定扫描时间，也可以是根据一定规则进行变化的间隔时间和扫描时间。
可参见图2所示，示出了图1中超声功能模块进行周期性扫描的一个示意图；从图2中可以看出，该超声功能模块12周期性地进行启动（每隔T1时间），且每次持续扫描T2时间。使用者（如医生或护士）在B/M模式下可以通过上述的扫描周期设置模块14设置上述T1及T2的值。例如，在一种特定应用场合中，使用者可以将该T1设置为30分钟，该T2设置为30秒，则该超声功能模块12就会每隔30分钟启动扫描测量，每次扫描测量持续30秒，每次扫描测量的结果均可以在存储模块16中存储。
相应地，本发明实施例提供了一种监护方法，其在如前述结合附图1及附图2所说明的监护设备上实现，用于同时实现常规监护生理参数监测以及超声扫描监测，其包括如下步骤：
通过监护功能模块10对被监测对象的常规生理参数进行监测，并对所获得的常规生理参数在显示设备上进行显示；
