具体实施方式
为使本发明的实施方式的目的、技术方案和优点更加清楚，下面将结合本发明的实施方式的附图，对本发明的实施方式的技术方案进行清楚、完整地描述。显然，所描述的实施方式是本发明的一部分实施方式，而不是全部的实施方式。基于所描述的本发明的实施方式，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施方式，都属于本发明保护的范围。
图1是根据本发明的一个实施方式的血氧仪的示意性结构图。
如图1所示，本实施方式的血氧仪1包括：

另外，微处理器4还可以包括开机启动画面处理单元41，所述开机启动画面处理单元41在所述开机按钮被按下后，基于所述存储单元存储的测量数据生成开机启动画面或读取所述存储单元存储的开机启动画面，并将开机启动画面发送给显示单元5。
本实施方式的血氧仪1可以是本领域公知的指夹血氧仪、腕式血氧仪或头戴式血氧仪等便携式血氧仪，也可以是医院使用的台式 血氧仪，本发明对此没有任何限制。
本实施方式的血氧仪1，在第一次使用时，开机时没有要显示的上一次的血氧饱和度的测量结果，开机后直接进入采集画面。
本实施方式的血氧仪1可以利用本领域公知的任何方法获得血氧饱和度。下面具体说明一个例子，但本实施方式并不限于此。
例如，如果测量时间小于1秒，则丢掉采集的数据，如果测量时间大于1秒，则记录数据。判断10秒采集的血氧数据的稳定性，主要根据波形的稳定性和数据的稳定性来判断，如果数据稳定则替换前10秒的数据，如果数据不稳定，则舍弃。
在第一次使用之后再次使用时，在开机时显示开机启动画面。
优选，开机启动画面包括上一次的血氧饱和度的测量结果和/或前几次的血氧饱和度的测量结果。进而优选，所述开机启动画面包括前几次的血氧饱和度的测量结果的趋势图。还优选，所述开机启动画面包括前几次的血氧饱和度的测量结果的平均值
图2是根据本发明的一个实施方式的血氧仪的开机启动画面的一例。如图2所示，开机启动画面的左侧为上一次的血氧饱和度的测量结果，右侧为前几次的血氧饱和度的测量结果的趋势图。另外，左侧的上一次的血氧饱和度的测量结果也可以被替换为前几次的血氧饱和度的测量结果的平均值。在图2所示的实例中，显示了前10次的血氧饱和度的趋势图，但是趋势图所包含的次数可以任意进行设置。
本实施方式中，开机启动画面处理单元41获得将前几次的血氧饱和度的趋势图的方法例如是，将每次测量的血氧饱和度作为纵轴，以次数作为横轴制作趋势图。在本实施方式中，趋势图以波浪线表示，但是也可以以本领域公知的其他方式表示。
图3是根据本发明的一个实施方式的血氧仪的开机启动画面的另一例。如图3所示，仅显示了前10次的血氧饱和度的趋势图，而没显示上一次的血氧饱和度。
另外，开机启动画面除了血氧饱和度，还可以包括脉搏、PI值等数据，本发明对此没有任何限制。
在本实施方式中，开机启动画面处理单元41基于本次的血氧饱和度的测量结果更新所述开机启动画面，并将更新后的开机启动画面发送给所述存储单元3，以供下次开机时进行显示。
另外，显示单元5以预定时间，例如10秒，显示述开机启动画面，在显示时间达到预定时间后，进入采集画面。
本实施方式的血氧仪1，在开机时可以显示上一次的血氧饱和度的测量结果和/或前几次的血氧饱和度的测量结果，让用户可以查看上一次的测量结果或前几次的测量结果的趋势，了解自身的身体参数水平和/或运动前后、吸氧前后的参数对比。
本实施方式的血氧采集单元2具有第一光发射单元21、第二光发射单元22和光接收传感器23。第一光发射单元21和第二光发射单元22例如是发光二极管即LED。第一光发射单元21发射例如660nm的红光，第二光发射单元22发射例如905nm、910nm或940nm的红外光。光接收传感器23例如是光敏传感器，接收第一光发射单元21和第二光发射单元22发射并未被人体吸收的光，并将其转换为电信号。
在具体工作过程中，可以是第一光发射单元21和第二光发射单元22交替发光，这样，光接收传感器23就能够交替接收到第一光发射单元21发射并未被人体吸收的红光和第二光发射单元22发射并未被人体吸收的红外光。另外，也可以是光接收传感器23包括两个传感器，每个传感器独立地接收第一光发射单元21和第二光发射单元22发射并未被人体吸收的光，这样，第一光发射单元21和第二光发射单元22就不需要交替发光，而可以连续发光。
另外，血氧采集单元2也可以包括三个以上光发射单元，以提高采集精度。
在血氧仪1是指夹血氧仪的情况下，血氧采集单元2包括可以 放入手指的内凹式血氧采集口，在所述内凹式血氧采集口内设置第一光发射单元21、第二光发射单元22和光接收传感器23。
在血氧仪1是腕式血氧仪的情况下，血氧采集单元2包括设置于壳体外部的血氧指夹，该血氧指夹与设置于所述壳体的接口连接。另外，腕式血氧仪的血氧采集单元2也可以设置在壳体内部。
具体地，图6是根据本发明的一个实施方式的腕式血氧仪的一例。如图6所示，腕式血氧仪1具有的血氧采集单元2即血氧指夹设置在外部，该血氧指夹与设置于所述壳体的接口连接。
在血氧仪1是头戴式血氧仪的情况下，血氧采集单元2也可以像腕式血氧仪那样设置在壳体外部或内部。在设置在外部的情况下，血氧采集单元2通过壳体上设置的接口进行连接。
血氧采集单元2将采集到的电信号发送给微处理器4，微处理器4基于接收到的电信号计算人体的血氧饱和度。微处理器4基于血氧采集单元2采集到的电信号计算血氧饱和度的方法可以本领域公知的任何方法，本发明不再赘述。
在本实施方式的显示单元5，在采集数据后，可以显示棒图、血氧值、脉率值、PI值和波形图的任意一种或多种，本发明对此没有任何限制。
具体地，图4是根据本发明的一个实施方式的血氧仪的显示单元所显示的画面的一例。图5是根据本发明的一个实施方式的血氧仪的显示单元所显示的画面的另一例。如图4所述，在显示单元5显示棒图、血氧值、脉率值和波形图。如图5所示，在显示单元5显示棒图、血氧值、脉率值和PI值。
本实施方式的血氧仪1优选还包括输入单元72，通过输入单元72设定所述开启启动画面的显示内容，即设定开机启动画面显示上一次的血氧饱和度的测量结果，还是显示前几次的血氧饱和度的趋势图，或者同时显示二者，或者代替上一次的血氧饱和度而显示前几次的血氧饱和度的平均值。
另外，通过输入单元72还可以设定上述预定时间、第一阈值、第二阈值、第三阈值、第一频率、第二频率、第三频率、第一持续时间、第二持续时间和第三持续时间中的至少一个。
输入单元72例如是按键，优选，按键是一个或多个在壳体内设置的从壳体表面凸起的弹性柱形按键，通过按下所述按键可以实现开关机、功能设置以及设置上述阈值、频率和持续时间。在输入单元72可以实现开关机功能的情况下，无需另外设置开机按钮71，即开机按钮71属于输入单元72的一部分。也就是说，输入单元72和开机按钮71可以接合为一个输入单元。
另外，也可以不设置输入单元72，而将输入功能设置在显示单元5。例如显示单元5具有触摸控制功能，用户通过显示单元5实现上述输入控制。
另外，本实施方式的血氧仪1优选还包括无线通讯单元8，其接收来自移动终端的参数设置指令，并将显示画面发送至移动终端。用户可以通过移动终端与无线通讯单元8实现通信，对血氧仪1进行控制，或将血氧仪1检测到的数据传送给移动终端。
另外，本实施方式的血氧仪1优选还包括电源单元6，电池单元6可以为干电池或者可充电电池，对血氧仪1的各个部件进行供电。
另外，本实施方式的血氧仪1优选还包括I/O接口9，I/O接口9例如是USB接口。在电池单元6为可充电电池的情况下，可以通过I/O接口9对电池单元6进行充电。
另外，I/O接口9可以作为外接其他血氧采集装置10的采集接口，这样可以连接传统的指夹式或者指套式的血氧采集装置，适合夜间或者长时监测。
另外，微处理器4在开机按钮被按下后，查询在存储单元中是否存储有测量数据，有则显示，没有则进入正常测量画面。
另外，所述微处理器基于用户信息，生成与所述用户相关的开机启动画面并发送给显示单元。优选，所述用户信息包括用户手动 选择的用户信息和/或经由传感器检测到的用户的生理信息。
具体地，在显示存储数据之前可以手动选择相应用户数据信息，也可以根据用户的生理信息识别用户。所述生理信息可以是光接收传感器转换输出的电信号，可以是输出信号的幅值信息，周期信息等信息，尤其是与脉搏波数据相关的信息，所述脉搏波数据信息可以是波形的特征值信息，也可以是脉率信息等其它可以由脉搏波获得的信息，根据所述信息搜索相对应的存储数据。所述存储数据包括用户非生理相关数据和生理相关数据，非生理数据包括但不限于年龄、性别、体重等，生理相关数据包括但不限于设置的阈值、测试时长、测试数据、测量数据的统计结果等。经过一定时间后，未搜索到匹配信息时采用默认设置，并更新存储用户相关信息；由于需要基于每次进行正常测试之前来识别用户，在每次测量结束后，用户可以关闭设备或设备退出正常测试。
另外，有可能用户只是为了查看测试的结果，此时，为了省电，在显示存储数据时不进行测试。
另外，所述微处理器，在达到所述预定时间之前，在检测到测量数据显示完毕，或者判定为所述光接收传感器的输出为有效信号的情况下，进入采集画面。
所述微处理器，在所述光接收传感器输出的频率信号的频率在预定的频率范围内，或者所述光接收传感器输出的电压信号的电压在预定的电压范围内时，判定为所述光接收传感器的输出为有效信号。
在所述光接收传感器输出的信号为频率信号的情况下：
在以第一级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则将发光强度降低到第二级发光强度，
在以第二级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则将发光强度降低到第三级发光强度，
在以第三级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则判定为所述频率信号不是有效信号，若小于等于第一频率，则判定为所述频率信号是有效信号。
具体地，显示测试数据的同时进行判定光接收传感器的输出是否是有效信号，检测到有效信号时则进入采集画面进行测试，或者当存储数据显示完成时进入采集画面，比等待固定时间T1再开始测试加快了数据的测量和显示速度。
有效信号的判断基于以下描述，光接收传感器接收的信号是未被人体组织吸收的信号，当人体血液充盈程度越大时，未被人体组织吸收的信号强度就会越小。设定阈值进行判定，例如当经过光接收传感器转换输出的电信号是频率信号时，可以设置大于某个频率范围时判定未检测到人体组织，进而判定此时输出不是有效信号；当输出的电信号是电压信号时，可以设置大于某个电压范围时判定未检测到人体组织，进而判定此时输出不是有效信号。由于不同的人体或人体组织存在差异，并且所述电信号与发光强度相关，当由于人体组织例如手指周长较小时，未被吸收的光信号就会较周长大的手指大很多，可以通过调整光强的办法来适应不同手指，扩大使用范围，比如当输出信号是频率信号时，当以第一级发光强度进行发光时，检测到传感器输出信号频率大于50KHz，将发光强度降低到第二级发光强度，再判断是否大于50KHz，如果是，将发光强度降低到第三级发光强度，进一步再判断是否大于50KHz，如果仍然是大于，则判定此时不是有效信号，否则可以判定此时是有效信号，以此来适应不同的人体组织。
进一步说，对于何时进入正常测量画面一般是设定一个固定时长，为了兼顾不同类型信息的显示，该固定时长需要按照最大时长进行设定。进而优选，为了提高开始测量的速度减少用户的等待时间，可以判定何时可进入正常测量画面，以此加快进入正常测量画面的速度，减少不必要的等待时间。具体是唤醒设备后显示存储数据的画面，设备实时检测是否可进入正常测量画面，当检测到可进 入正常测量画面后，停止存储数据画面的显示；
具体地，检测是否可进入测量画面由可进入标志进行指示，当微处理器检测到该标志后停止存储数据的显示，进入正常测量画面。进一步，在判断是否可进入正常测量画面之前包括，在显示存储数据时微处理器开始接收光接收传感器的输出信号，并对该信号进行判定是否是有效信号，当微处理器检测到存储数据的显示完成且检测到有效信号时即刻进入正常测量画面，或者是微处理器对光接收传感器去的输出信号进行处理，当获得测量数据且微处理器检测到存储数据的显示完成且检测到有效信号时即刻进入正常测量画面，所述测量数据可以是血氧饱和度数值或者脉率数值。为了防止存储数据显示完成但微处理器一直未检测到有效信号或有效数据时一直进行的等待，可以设定一默认时长，在唤醒设备时该计时同时开启，当微处理器检测到前述可即刻进入测量画面或所述计时时间到满足之一条件时即刻进入测量画面。
另外，所述微处理器基于存储的测量数据的统计结果，将显示单元的显示空间划分为多个子空间，以子空间的大小和统计结果正相关的方式进行显示。优选，对较小的子空间采用鲜艳的颜色进行显示。
具体地，根据存储的生理相关数据的类型来选取显示的方式，数据的类型指上N次测量的N个数据(特指每次获得一个存储数据)、上N次测量的N段时间的数据的统计结果，由于设备可以外接血氧单元，当需要测量一段数据时优选采用外接血氧单元，而设备内部的血氧单元优选在测量单次数据时采用。当显示的数据是生理相关的多个单次数据时可以采用切换显示或者趋势图显示，当显示生理相关数据的统计结果时优选采用面积图显示，按照段数N将显示空间划分为N个子空间，所述子空间的大小和数据的统计结果正相关，比如存储的数据中有3段血氧饱和度的数据，数值包含50个99％，30个98％，10个97％，10个96％，存储的数据包含了4个不同数值则将显示空间划分为4个子空间，数据的个数是 50+30+10+10＝100个，空间整体为100份，其中数值为99％的子空间占显示空间的50％，数值为98％的子空间占显示空间的30％，数值为97％的子空间占显示空间的10％，数值为96％的子空间占显示空间的10％。并在每个对应子空间上标注对应的数值信息。所述子空间进一步可以采用不同的颜色进行标注，对于空间占比较小的数据采用更加鲜艳的颜色进行标注，比如子空间为10％采用红色，50％的用绿色。基于该显示面积的显示更易于查看统计结果，加入颜色的区分标识之后对于少数可能的异常数据采用鲜艳颜色能更易于引起注意。
另外，所述微处理器在测量数据的趋势图中截取包括出现异常之前的数据和刚出现异常时的数据的部分，以及包括异常结束时的数据和异常结束之后的数据的部分，进行显示。
具体地，存储数据趋势图存在显示特例，当该图包含的数据量较大时尤其是当数据的个数超过一个屏幕所能显示的个数之后，需要切换到下一页继续显示数据，当用户想查看某段数据时需要挑选数据和切换显示，不便于操作，尤其是存在超过阈值数据时用户会关注超限数据之前和之后数据的变化趋势，在正常数据之间存在异常数据时，尤其异常数据持续的数据超过一屏显示，或者多次反复显示数据超过一屏显示时，查看数据比较麻烦，此时可以采用如下显示方式，调取异常数据之前的数据和刚出现异常时的数据段进行显示，同时调取异常数据之后和异常数据结束是的数据段进行显示，所述截取两段数据上下排列显示，便于对比。
另外，所述显示单元以预定的频率切换显示采集画面和对存储的测量数据进行显示的画面，或者在采集画面的子画面中显示存储的测量数据。优选，所述显示单元，在存储的测量数据中存在超过阈值的数据时，以闪烁的方式进行显示。
具体地，进入正常测量画面后，在测量画面的子画面中显示存储数据或者切换显示存储数据，以此便于对比查看此次的测量数据和存储数据的差异。数据的切换显示解决了由于显示空间限制的问 题。进而，当设置了阈值数据且存储数据中存在超过阈值的数据时，在显示所述数据时采用闪烁提醒注意上次的异常信息。
以上虽然通过一些示例性的实施方式详细地描述了本发明的血氧仪，但是以上这些实施方式并不是穷举的，本领域技术人员可以在本发明的精神和范围内实现各种变化和修改。因此，本发明并不限于这些实施方式，本发明的范围仅以所附权利要求为准。

    所述光接收传感器输出的信号为频率信号，
    在以第一级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则将发光强度降低到第二级发光强度，
    在以第二级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则将发光强度降低到第三级发光强度，
    在以第三级发光强度进行发光时，检测所述频率信号的频率是否大于第一频率，若大于第一频率，则判定为所述频率信号不是有效信号，若小于等于第一频率，则判定为所述频率信号是有效信号。
