【背景技术】
目前市场上尚未有具有自动预稀释功能的自动进样血液细胞分析仪。而具有自动预稀释功能的自动进样血液细胞分析仪中通常会使用到预稀释试管，由于预稀释试管没有试管帽，在自动进样过程中如果用其进行混匀操作，会造成样本的溅出，从而造成污染。因此，具有自动预稀释功能的自动进样血液细胞分析仪亟需解决预稀释试管的识别并根据试管类型控制自动进样流程的问题。
因此，现有技术还有待于改进和发展。
【发明内容】

本申请还提供一种自动进样血液分析仪，在所述分析仪中安装有上述的试管自动进样识别装置。
本申请通过提供一种自动进样血液分析仪，同时支持全血模式和自动预稀释模式，因此会涉及两类试管：全血试管和预稀释试管。全血试管有试管帽，支持自动进样过程中血液的混匀；预稀释试管没有试管帽，自动进样过程中是严禁混匀的。所述自动进样血液分析仪在自动进样过程中能够自动识别全血试管和预稀释试管，并根据不同的试管类型决定自动进样流程。
应当理解的是，本申请的应用不限于上述的举例，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，所有这些改进和变换都应属于本申请所附权利要求的保护范围。
