Description
しかし、特許文献1では、検体液を重力によって流れさせていることから、例えば、検査キットの使用に際しては、一定の方向を下方にしなければならず、取り扱いに制約が生じる。また、特許文献1では、コックによって流れを制御していることから、例えば、検査キットの構成が大掛かりとなりやすい。このように、検査キットの構成が複雑化あるいは大型化したり、検査方法に制約が生じている。
図1は、本発明の実施形態に係るセンサ1(検体液センサ)を示す斜視図である。
図5(a)〜図5(e)および図6(a)〜図6(e)はセンサ1を用いた検体液の検査方法の手順を説明するための図である。これらの図では、フィルタ7、第1流路29および第2流路31の平面形状等を模式的に示している。
以上に説明したセンサおよび当該センサを使用した検査方法は種々変形可能であり、以下では、その変形例を列挙する。
