    • An optical sensor based on a broadband light source and cascaded waveguide filters comprises a broadband light source, an input waveguide, a reference ring resonator coupled with the input waveguide, a common bus waveguide coupled with the reference ring resonator, a sensing ring resonator coupled with the common bus waveguide, an output waveguide coupled with the sensing ring resonator, and two optical power detectors. At least a portion of the sensing ring resonator is influenced by the physical parameter to be measured or in contact with an analyte. The variation of the physical parameter to be measured or the variation of the analyte induces a shift of the transmission spectrum of the sensing ring resonator. By using the cascaded filtering effect of the double resonators, the wavelength shift can be translated into a variation of the total output power. Consequently the physical parameter to be measured can be easily deduced.
    • 基于宽带光源和级联波导滤波器的光学传感器包括宽带光源,输入波导,与输入波导耦合的参考环形谐振器,与参考环形谐振器耦合的公共总线波导,耦合到 公共总线波导,与感测环谐振器耦合的输出波导和两个光功率检测器。 感测环谐振器的至少一部分受被测物理参数或与分析物接触的影响。 要测量的物理参数的变化或分析物的变化引起感测环形谐振器的透射光谱的偏移。 通过使用双谐振器的级联滤波效应,波长偏移可以转化为总输出功率的变化。 因此,可以容易地推导要测量的物理参数。

    • A mono cusped patch for repairing cardiac outflow tract is disclosed in the present invention, which comprises an inner patch, an external supporting patch and a leaflet. An approximate semicircular slit is provided on the inner patch. The inferior border of the leaflet is set between the inner patch and the external supporting patch along the slit. The inner patch, the inferior border of the leaflet and the external supporting patch are stitched together along the slit edge of the inner patch with sutures. The inferior border of the leaflet is fixed between the inner patch and the external supporting patch. According to this special stitching structure, the present invention also provides a valved conduit of good performance. The leaflets of mono cusped patch and valved conduit are sutured with the inner patch/conduit and external supporting patch/conduit to repair cardiac outflow tract, and the inferior border of leaflet is provided between the inner patch/conduit and external supporting patch/conduit, so that the present invention avoids fixing leaflet only with sutures, makes leaflets more durable and improves postoperative longtime treatment effect of patients significantly.
    • 在本发明中公开了一种用于修复心脏流出道的单色贴片,其包括内部贴片,外部支撑贴片和传单。 在内贴片上提供近似的半圆形狭缝。 小叶的下边界沿着狭缝设置在内部贴片和外部支撑贴片之间。 内部贴片,小叶的下边界和外部支撑贴片通过缝合线沿着内部贴片的狭缝边缘缝合在一起。 传单的下边界固定在内部补丁和外部支撑补丁之间。 根据这种特殊的缝合结构,本发明还提供了具有良好性能的阀门导管。 用内部贴片/导管和外部支撑贴片/管道缝合单孔贴片和瓣膜导管,以修复心脏流出道,并且在内部贴片/导管和外部支撑贴片/导管之间提供小叶的下边缘, 使本发明避免仅用缝线固定传单,使传单更耐用,显着提高患者术后长期治疗效果。
