    摘要： There is provided a tracheal catheter designed so that a suction catheter may be used to suction out any secretions that accumulate in the zone above the balloon. There is further provided a tracheal catheter having a ventilation lumen with a flexible wall to provide a flexible lumen which takes up negligible volume when the catheter is not inserted. The suction catheter may be inserted into the flexible lumen, bending the flexible lumen wall that normally lies substantially flat against the ventilating lumen. As the suction catheter is inserted into the lumen, the lumen opens to accept it. When the catheter is removed, the wall of the flexible lumen moves back into position against the ventilating lumen wall, again taking up negligible volume. There is also provided a method of suctioning the subglottic space of an intubated patient. This involves providing a tube as described above, inserting a catheter into the flexible lumen from the proximal end, and providing suction to the proximal end of the catheter.

    摘要翻译： 提供了气管导管，其设计成使得可以使用抽吸导管来抽出积聚在气球上方的区域中的任何分泌物。 还提供了一种气管导管，其具有带柔性壁的通气腔，以提供柔性内腔，当未插入导管时，该内腔占据可忽略的体积。 吸引导管可以插入到柔性管腔中，弯曲通常基本上平坦地抵靠通气腔的柔性管腔壁。 当抽吸导管插入内腔时，管腔打开以接受。 当导管被移除时，柔性内腔的壁移动回到相对于通气腔壁的位置，再次占据可忽略的体积。 还提供了一种抽吸插管患者的声门下空间的方法。 这涉及提供如上所述的管，从近端将导管插入柔性管腔中，并且向导管的近端提供吸力。

    摘要： A manually actuated breast pump is provided. The breast pump has a breast cup, pump mechanism and a container. The components of the breast pump are easily assembled and disassembled to facilitate use, cleaning, manufacture and transport. The breast pump can apply a negative pressure, a positive pressure or both to a user's breast. The breast pump provides fluid isolation between the pressure source and the expressed milk.

    摘要： A multiple access communications system comprises a node spacecraft GEO and several user spacecraft LEO.sub.1 to LEO.sub.n. Each user spacecraft LEO.sub.1 to LEO.sub.n includes a transmit/receive terminal head 18.sub.1 to 18.sub.n, and the node spacecraft GEO includes n transmit/terminals 22 to 22.sub.n and a single beacon unit 24. The beacon beam may be operated to initiate acquisition phases which allow two-way communication to be established between the transmit/receive terminals 22.sub.1 to 22.sub.n on the node spacecraft and the transmit/receive terminals 18.sub.1 to 18.sub.n on the corresponding user terminals. The acquisition phases include a period during which the beacon scans an uncertainty cone associated with the node spacecraft. This scanning period is reduced for second and subseqeunt acquisitions by using the first and subsequently acquired communication links to provide a more accurate estimate of the angular attitude of the node spacecraft, thus reducing the extent of the uncertainty cone.

    摘要： This invention relates to mechanisms for steering or pointing transmitted optical radiation beams and/or the look directions from which optical radiation beams are received. It also relates to optical communications systems incorporating such mechanisms, more particularly but not exclusively interspacecraft communications systems.

    摘要： A satellite antenna arrangement for a satellite communication system comprising: a reflector for producing a far field pattern with near-zero field strength at a predetermined location to reject unwanted signals from said predetermined location or minimise signal power transmitted to said predetermined location, the reflector having a surface comprising a stepped profile arranged to generate the near-zero field strength in the predetermined location. The stepped profile may comprise a radial step. The location of the near-zero field strength can be steered by moving the reflector or by adjusting the amplitude and phase of an additional beam that covers substantially the same region as the main beam reflected by the reflector.
