Description
本发明涉及一种用于测量耳温的温度计及使用该温度计来测量耳温的方法。具体来说，本发明揭示了一种用于改善温度计测量结果，以提高测定鼓膜温度的测量结果的正确性的方法。
红外耳温枪测量鼓膜温度的原理是将装有红外传感器的探头伸入耳内接收红外辐射能量，再将该能量转换为对应的温度值。理论上，探头直接对准鼓膜，则红外传感器接收的就是鼓膜的红外辐射能量，则转换出的温度值就是鼓膜的温度。
但实际上探头伸入耳内受到诸多因素的影响而不能直接对准鼓膜，或者接收的红外能量并不完全是鼓膜所辐射的，所以测量的温度读数就有了误差。这些因素包括：耳道的几何结构的复杂性、鼓膜周围受环境影响而温度相对较低、耳道内有毛发或耳垢等杂物。
为了解决此问题，美国专利5,626,147提出使用多个红外传感器来收集温度参数，并通过这多个参数来确定鼓膜的修正温度以校正探头不同深度和安放位置所引起的位置误差。但是，使用多个传感器不仅成本增加，而且结构设计和安装难度也增加，不利于工业生产。
另一美国专利6,358,216提出在设备上使用带有辐射源的检测器，辐射碰到组织会发生反射漫射，根据检测器所接收到的辐射强度判断探头是否对准鼓膜。虽然该专利中提到要降低辐射强度以减少对鼓膜红外测量的影响，但是使用了辐射源，用户多少会有影响，而且确保对准鼓膜需要花费一定时间，同时也依赖于机会。

图1是本发明的耳温测量装置的结构示意图；
图2是本发明的寻找最高耳温的方法的一个实施方案的流程图；
图3是本发明的寻找最高耳温的方法的另一实施方案的流程图；
图4是本发明的寻找最高耳温的方法的再一实施方案的流程图。
下面将参考附图和具体实施方案来详细说明本发明。
参见图1，示出了本发明的耳温测量装置的结构示意图。耳温测量装置包括红外传感器、信号输出装置和微处理器。红外传感器安装在一探头内，用来测量耳内的红外辐射能量，将所获得的信号通过放大电路放大后传输给微处理器。信号输出装置用于将所获得的信息传输给使用者。信号输出装置包括显示装置，例如用于直接显示温度或其它信息的LCD，或者是LED，可以发出光信号，例如频闪、持续性发光或者间隔时长不同的闪光，还可以是蜂鸣器，可以发出声音信号对使用者进行提醒、警示或告示。耳温测量装置可以具有按键，例如启动按键，或者可以在启动按键之外还具有工作按键，例如测量按键。可以通过启动按键启动装置后即使微处理器处于测量状态，还可以在启动后，通过另一按键的操作使
微处理器处于测量状态。
下面将通过图2-4进一步详细说明本发明的耳温测量装置的测量方法。
参见图2-4，启动温度计，温度计进入预定的工作模式，再将探头伸入耳道内，再按一下测量按键，则微处理器进入多次测量模式，此时维持探头在耳道内的角度和深度不变一段时间进入测量过程。
在该测量模式下，微处理器将执行包括以下步骤的测量过程：
A)通过所述红外传感器测量耳内的红外辐射能量，并根据所述红外辐射能量计算被测耳内的温度；
B)通过所述信息输出装置输出有关所获得的温度的信息，用以提醒使用者轻微调整耳温测量装置的测量角度，即探头在耳道内的角度；
C)再次通过所述红外传感器测量耳内的红外辐射能量，并根据所述红外辐射能量计算被测耳内的温度；
D)通过所述信息输出装置输出有关所获得的温度的信息，用以提醒使用者轻微调整耳温测量装置的测量角度和以便使用者决定是否继续测量；
E)判断使用者是否继续测量，如果是，则重复所述步骤C)和D)，否则，计算在耳温测量过程中所获得的耳温测量值中的最大值，并将所述最大值作为耳温测量过程的最终测量值，结束耳温测量过程。
在步骤B)中，输出有关所获得的温度的信息的同时，手柄内的声或光的元件可以提示该辐射区域的温度值测量完毕，以便提醒使用者轻微调整探头在耳道内的角度，使得探头对准另一个辐射区域，进行下一区域的测量。
在调整探头后再次获得温度数据并显示，使用者根据所显示的温度判断是否要继续测量，而这时温度计需要判断使用者是否还在继续测量。当使用者不再测量时，使用者从耳道中拿出温度计或者对按键进行相应的操作，这时温度计对使用者的意图的判断可以采用以下方法：
一是根据检测到的温度稳定程度来判定。当使用者从耳道中取出温度计时，所再次测得的温度将为体外温度，那么可以将本次温度与上一次测得的温度比较，如果上一次与本次测量结果之差大于2℃，则说明温度计已经被从耳道中取出，因此可以结束测量。反之，则说明温度计还在耳道中，那么可以继续测量。或者判断本次温度是否低于35℃，如果不低于35℃，说明还在耳道内，如果低于35℃，
则说明已经取出，可以结束测量。
二是需要结束测量时，由使用者通过按键操作来反映。在一种情况下，使用者在启动测量状态时按下按键不松开，因此当使用者决定不再测量时，松开按键，则结束测量，反之持续按下按键时继续测量。在另一种情况下，使用者在启动测量状态时按下按键，随后松开，即按下按键一次，温度计持续处于测量状态。当使用者决定结束时再按一次按键，在温度计退出测量状态结束测量。
每当显示一次数值时，温度计可以发出提示信号，例如提示音或提示性闪光，以便提醒使用者调整角度。在使用者决定继续测量的情况下，探头进入另一辐射区域，或者等待一定时间，比如1-3秒后，测量得出另一个温度值并存储。使用相同的方法，使用者多次调整探头，得出多个辐射区域的温度值。
在判断使用者不再继续测量时，温度计可以发出提示音或闪光提示，向使用者提示测量过程将结束，随后退出测量状态。这时，微处理器将前面所获得的结果进行计算和比较，得到最大值作为鼓膜的温度值，并在温度计上显示作为最终结果。
上面结合附图和具体实施例对本发明的实施方式作了详细的说明，但是本发明不限于上述实施方式，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下做出各种变化。
