    • The construction machine according to the invention is distinguished by the fact that an air-processing apparatus (28) is arranged outside the cab (9) on the machine frame (2), wherein a device (13, 22) for feeding processed and/or fresh air into the cab and used air from the cab is provided, said device having a feed air duct for processed air for the cab and a discharge air duct for used air from the cab. The feed air duct of the air-processing apparatus (13, 22) is connected to the outlet (28C) of the air-processing apparatus (28) and the discharge air duct is connected to the inlet (28B) of the air-processing apparatus. In a construction machine whose control station is rotatably arranged on the machine frame, the arrangement with the air-processing apparatus outside the cab has the decisive advantage that it is not necessary to run hoses and/or lines between the rotatable cab and the machine frame. A preferred embodiment of the construction machine provides for the feed and discharge air duct of the air-processing apparatus (13, 22) to have an outer section (30) which is formed by a component connected to the machine frame in a rotationally fixed manner and an inner section (31) which is formed by a component connected to the cab in a rotationally fixed manner, wherein the outer section encloses the inner section. Thus concentric air conduction via the swivel joint of the control station is possible.
    • 根据本发明的施工机器的特征在于,在机架(2)上的空气处理设备(28)布置在驾驶室(9)的外部,其中,用于将加工和/ 或新鲜空气进入驾驶室并且使用来自驾驶室的空气,所述装置具有用于驾驶室的加工空气的进给空气管道和来自驾驶室的用过的空气的排放空气管道。 空气处理装置(13,22)的送风管与空气处理装置(28)的出口(28C)连接,排气管与空气处理装置(28B)的入口 仪器。 在其控制站可旋转地布置在机架上的施工机械中,与驾驶室外的空气处理设备的布置具有决定性的优点,即不需要在可旋转驾驶室和机架之间运行软管和/或线 。 施工机械的优选实施例提供了空气处理设备(13,22)的进料和排出空气管道,其具有由旋转固定的方式连接到机架上的部件形成的外部部分(30) 以及由旋转固定的方式连接到驾驶室的部件形成的内部部分(31),其中外部部分包围内部部分。 因此,可以通过控制站的旋转接头进行同心的空气传导。

    • A disposable seal assembly for use with a reusable cannula preferably includes a flapper valve fluid seal and at least one instrument seal. The instrument seal has a sacrificial flange and a sealing flange that protrude from an inner baffle connected to the assembly's main body by a flexible outer baffle, and at least one elastomeric rib extending between the inner baffle and the body to prevent inversion of the inner baffle. Preferably, a surface of the sacrificial flange is configured to prevent the flanges from sticking together during use. An adaptor, tethered to the assembly's main body, has a central channel with an hourglass profile, a concave distal flange, distal bumpers for preventing the adaptor from translating too far into the main body, and a grip portion shaped to allow a user conveniently to separate the adaptor from the main body. Other aspects include systems with a reusable cannula, and methods for using such systems.
    • 与可重复使用的套管一起使用的一次性密封组件优选地包括挡板阀流体密封件和至少一个仪器密封件。 仪器密封件具有牺牲凸缘和密封凸缘,其从通过柔性外挡板连接到组件主体的内挡板突出,并且至少一个弹性肋在内挡板和主体之间延伸以防止内挡板反转 。 优选地,牺牲凸缘的表面构造成防止凸缘在使用期间粘在一起。 连接到组件主体的适配器具有一个具有沙漏轮廓的中心通道,一个凹形的远端凸缘,用于防止适配器平移到主体太远的远侧缓冲器,以及一个形状适于使用户方便地 将适配器与主体分开。 其他方面包括具有可重复使用的套管的系统以及使用这种系统的方法。
