下面将参考附图并结合实施例来详细说明本申请的技术方案。
实施例1
本实施例提供一种全自动化学发光免疫分析仪液路中气泡检测 系统，如图1所示，包括：
液路管道1，由透光材料制成，比如常见的医用透明塑料；
密封安装座2，套设在所述液路管道1上；
红外线发生器3，设置在密封安装座2内位于液路管道1的一侧，用于发出红外线；
红外线感应器4，设置在密封安装座2内位于液路管道1的另一侧，用于接收红外线发生器3发出的并穿过所述液路管道1的红外线，并输出电流信号；
微型处理器5，用于接收红外线感应器的电流信号，并将电流信号与设定的气泡大小与电流信号的关系式进行匹配，并输出气泡的大小。
本实施例的全自动化学发光免疫分析仪液路中气泡检测系统，在液路管道1上设置密封安装座2，密封安装座2起到安装其他部件的作用，同时又时液路管道1上形成一个“暗室”部分，红外线发生器3发出红外线，红外线感应器4接收红外线发生器3发出的并穿过所述液路管道1的红外线，当液路管道1内有气泡时，其整体透光性就会增强，也即红外线感应器4会感应到更多的红外线，其电流信号也更强，微型处理器5还可以根据过大的电流信号来进行警报，提醒使用者通过的液体中含有气泡，从而实现了对管道中气泡的检测。
需要指出的是，这里的暗室只是针对一般而言，阻挡了大部分的光线，不可能也没有必要做到无任何光线的完全暗室。
优选地，所述红外线感应器6输出电流信号先经过放大器放大电 流后再与微型处理器5连接。放大器为常见的电路，能够放大所述红外线感应器6的输出电流，提高灵敏度。
实施例2
本实施例提供一种全自动化学发光免疫分析仪液路中气泡检测系统，如图2所示，包括：
液路管道1，由透光材料制成，比如常见的医用透明塑料；
密封安装座2，套设在所述液路管道1上，形成红外暗室空间；
红外线发生器3，设置在密封安装座2内位于液路管道1的一侧，用于发出红外线；
红外线感应器4，设置在密封安装座2内位于液路管道1的另一侧，用于接收红外线发生器3发出的并穿过所述液路管道1的红外线，并输出电流信号；
微型处理器5，用于接收红外线感应器的电流信号，并将电流信号与设定的气泡大小与电流信号的关系式进行匹配，并输出气泡的大小。
微型处理器5还可以与警报器连接，当电流信号过大时(存在气泡)发出警报告知相关人员。
所述液路管道1包括管道本体10，分布在密封安装座2所包围空间的位于红外线发生器3两侧的玻璃制成的折光体11，所述折光体11为凹透镜(折光体11整体为一凹透镜，只不过中心成型有供液体通过的流道，该流道与管道本体10的流道直径相等)。也即在液路管道1的密封安装座2内嵌入了一段折光体11，通过凹透镜将光线 发散，从而使得密封安装座2外部沿液路管道1射入的环境中的红外线(外部光线不可避免地从两侧射入到密封安装座2内)，能够被凹透镜发散，而无法到达红外线感应器4区，从而克服红外线感应器4接收到环境中的红外线，降低环境中红外线对检测结果的影响。
所述折光体11的两侧均为凹面，也可以是朝向外的一侧为凹面，另一侧为平面。
作为一种替代的实施方式，如图3所示，所述液路管道1包括管道本体10，分布在密封安装座2所包围空间的位于红外线发生器3两侧的玻璃制成的折光体11，所述折光体11为凸透镜，且两个凸透镜对于红外线的交点位置位于红外线感应器4接收范围之外。
也即通过调整折光体11的焦点和设置位置，使密封安装座2外部沿液路管道1射入的环境中的红外线，能够在红外线感应器4接收范围之外汇聚，从而避免环境中的红外线射入红外线感应器4，降低环境中红外线对检测结果的影响。
实施例3
本实施例提供一种全自动化学发光免疫分析仪液路中气泡检测方法，使用上述的全自动化学发光免疫分析仪液路中气泡检测系统；
包括以下步骤：
S1：建立红外线感应器输出电流信号与气泡大小的关系曲线；

其中k表示红外线感应器输出电流信号与气泡大小的关系曲线中，在一个管道横截面内，气泡所占的面积与红外线感应器输出电流信号的比例系数。
