    • An apparatus for measuring the concentration of an analyte in a sample extracted from the skin (10) of a patient comprises a collection chamber (3) adjacent to the skin; a radiation source (7) configured to irradiate the sample in the collection chamber (3); a reflector (4) configured to reflect incident radiation back through the sample; and a sensor (11) configured to measure the radiation emitted from the sample. The reflector (4) may shield the skin (10) from the incident radiation and have a convoluted or perforated shape to permit sufficient diffusion of the extracted analyte to all parts of the surface of the reflector from its edges. The reflector (4) may be a reflective surface of reverse iontophoresis electrodes (9) used to extract the sample from the skin. In a further apparatus the reflector (4) is implanted beneath an outer layer of the skin (10) so that instead of being extracted, the sample can be measured in vivo. An implanted reflector (4) may be formed from an assemblage of reflective particles. A mask (5) may be provided to prevent the incident radiation bypassing the reflector (4).
    • 用于测量从患者皮肤(10)提取的样品中的分析物的浓度的装置包括与皮肤相邻的收集室(3); 辐射源(7),被配置为将样品照射在收集室(3)中; 反射器(4),被配置为将入射的辐射反射回所述样品; 以及被配置为测量从样品发射的辐射的传感器(11)。 反射器(4)可以将皮肤(10)从入射的辐射屏蔽起来,并且具有回旋或穿孔的形状,以允许提取的分析物从其边缘向反射器表面的所有部分充分扩散。 反射器(4)可以是用于从皮肤提取样品的反向离子电渗电极(9)的反射表面。 在另一个装置中,反射器(4)被植入在皮肤(10)的外层之下,使得不是被提取,所以可以在体内测量样品。 植入的反射器(4)可以由反射颗粒的组合形成。 可以设置掩模(5)以防止旁路反射器(4)的入射辐射。
