    • The invention relates to a sensor probe (100,110,120,130,140,150) for detecting an environmental state within a bodily lumen. The sensor probe (100,110,120,130,140,150) having an elongated body (9) comprises an optical guide (1) having an outcoupling surface (11),which is part of an end surface (3) of the elongated body (9), facing a reflective surface of an overhanging part (22,42,52,62), a photodetector which detects a property of light which is composed of light (32) in the optical guide (1) that is reflected from the outcoupling surface (11) of the optical guide (1) and of light (33) in the optical guide (1) that is reflected from the overhanging part (22,42,52,62), and a hydrogel material(2) of which a property changes when getting into contact with an environmental material and/or when detecting an environmental change, and which is provided between the end surface (3) of the elongated body (9)and the overhanging part (22,42,52,62). In this way a sensor probe (100,110,120,130,140,150) is provided that, because of its compactness, can be applied inside the bodily lumen for detecting and characterizing parameters that are vital indicators for the state of the human or animal body, and to which the hydrogel material (2) is responsive.
    • 本发明涉及一种用于检测体腔内的环境状态的传感器探针(100,110,120,130,140,​​150)。 具有细长主体(9)的传感器探针(100,110,130,140,​​150)包括具有外耦合表面(11)的光导(1),该外耦合表面(11)是细长主体(9)的端表面(3)的一部分,面向反射表面 突出部分(22,42,52,62)的光检测器,其检测由光导(1)中的光(32)组成的光的属性,所述光从光耦合表面(11)反射 在导光体(1)中从突出部分(22,42,52,62)反射的导光体(1)和光(33)以及在接触时性质发生变化的水凝胶材料(2) 和环境材料和/或当检测到环境变化时,并且设置在细长体(9)的端面(3)与伸出部分(22,42,52,62)之间。 以这种方式,提供传感器探针(100,110,120,130,140,​​150),由于其紧凑性,可以在身体内部施加以检测和表征作为人或动物体状态的重要指标的参数,并且将水凝胶材料 (2)有反应。
