    • Fluid lens system, e.g. for medical imaging or medical treatment, with a container enclosing a fluid arranged to refract incoming waves. A pressure release mechanism is in contact with the fluid so as to compensate changes in its volume due to thermal variations, e.g. during high temperature medical cleaning. This pressure release mechanism is positioned within a pathway of incoming waves. In preferred embodiments a fluid container connected via a tube to the fluid as a reservoir, is arranged within or outside the container, e.g. beyond an image sensor. Alternatively, an easily compressible body, e.g. a small closed metal bellows enclosing a gas, is positioned inside the fluid to absorb volume changes by compression. In both embodiments, the pressure release elements are preferably positioned in a peripheral part of the pathway of incoming waves to not affect performance of the lens. In another aspect, a fluid lens includes a container with an inner container part that fits inside an outer container part, wherein the inner container part is in rigid connection to at least a one boundary arranged for penetration of incoming waves. The pressure release mechanism is positioned within the outer container part, and it is in contact with the fluid so as to compensate changes in volume of the fluid due to thermal variations. In one embodiment the inner and outer container parts are arranged for relative one-dimensional movement and fluid tight interconnected. In another embodiment, a fluid filled cavity is formed between the inner and outer container parts, and this cavity houses a compressible body. The lens systems are suited for applications such as medical endoscopes, catheters and needles, optically as well as acoustically based.
    • 流体透镜系统,例如 用于医疗成像或医疗处理,容器包围布置成折射入射波的流体。 压力释放机构与流体接触,以便补偿由于热变化引起的体积变化,例如, 在高温医疗清洗过程中。 该压力释放机构位于入射波的通路内。 在优选实施例中,经由管连接到作为储存器的流体的流体容器设置在容器内或外部,例如, 超越图像传感器。 或者,容易压缩的主体,例如, 围绕气体的小封闭金属波纹管位于流体内部以通过压缩吸收体积变化。 在两个实施例中,压力释放元件优选地定位在入射波通路的周边部分中,从而不影响透镜的性能。 在另一方面,一种流体透镜包括具有内部容器部分的容器,该内部容器部分装配在外部容器部分内部,其中内部容器部分刚好连接至布置成用于穿透入射波的至少一个边界。 压力释放机构位于外部容器部分内,并且与流体接触以便补偿由于热变化引起的流体体积的变化。 在一个实施例中,内部和外部容器部件布置用于相对一维运动并且流体密封互连。 在另一个实施例中,在内部和外部容器部分之间形成流体填充空腔,并且该空腔容纳可压缩体。 透镜系统适用于诸如医用内窥镜,导管和针的应用,光学和声学基础。

    • The present invention relates to a fluid sample take-up device for collection in a fast and controlled way, fluid samples such as body fluid ready for testing. In a first aspect, the present invention provides a fluid sample take-up device comprising a hollow tube having a first portion and a second portion remote from the first portion, an absorbent pad, e.g. for taking up a fluid sample such as for example a bodily fluid sample, within the first portion of the hollow tube, and extraction means for squeezing sample fluid from the absorbent pad towards the hollow tube so as to guide the sample fluid to the second portion through the hollow tube. The fluid sample is squeezed through the absorbent pad into the hollow tube. An advantage thereof is that the fluid sample is filtered by the absorbent pad, which allows particles and/or large proteins to be removed from the fluid sample, so that only the low viscosity part of the fluid sample is guided through the hollow tube.
    • 本发明涉及一种用于以快速和可控方式收集的流体样品收集装置,流体样品例如准备进行测试的体液。 在第一方面,本发明提供了一种流体样品收集装置,其包括具有第一部分和远离第一部分的第二部分的中空管,例如吸收垫。 用于在中空管的第一部分内吸收例如体液样品的流体样品,以及用于将样品流体从吸收垫挤压到中空管的提取装置,以将样品流体引导到第二部分 通过中空管。 流体样品通过吸收垫挤压入中空管。 其优点是流体样品被吸收垫过滤,吸收垫允许从流体样品中除去颗粒和/或大的蛋白质,使得仅液体样品的低粘度部分被引导通过中空管。
