    • A drive mechanism for a hospital bed effects relative vertical movement of a base and a patient litter. The drive mechanism includes spaced, telescoping threaded screw assemblies, which are driven by a single electric motor through a train of gears having helical teeth oriented to offset inherent frictional forces of the screw assemblies. A support for the motor and a component of the drive train are made of electrically nonconductive materials to electrically isolate the motor, and are arranged to damp vibrations produced by the motor. Two coiled electrical cords extend between the base and patient litter, and are each received in a recess in the patient litter when the patient litter is adjacent the base. A sensor arrangement provides an electrical signal indicative of the relative vertical positions of the patient litter and base, and a manual drive arrangement is provided to permit the gear train to be manually driven.
    • 用于医院床的驱动机构影响基部和患者垫料的相对垂直运动。 驱动机构包括间隔开的伸缩螺纹组件,其由单个电动机通过一系列齿轮驱动,其具有定向成抵消螺钉组件的固有摩擦力的螺旋齿。 电动机和传动系的部件的支撑件由不导电材料制成,以使电动机电隔离,并且被布置成阻尼由电动机产生的振动。 两条卷绕的电线在基部和病人垃圾之间延伸,当患者垃圾与基部相邻时,它们都被接收在病人垃圾中的凹槽中。 传感器装置提供指示病人垃圾和底座的相对垂直位置的电信号,并且提供手动驱动装置以允许手动驱动齿轮系。

    • A patient support incorporates a patient retention device includes frame, a rotatable shaft, a torque-producing device, and a flexible restraint member. The shaft has a cantilevered portion that extends from the frame and windably receives the flexible restraint member at the cantilevered portion. Optionally, a winding member is releasably coupled to the cantilevered portion of the shaft for receiving the flexible restraint member. The winding member is non-rotatable relative to the shaft, and is readily removable and replaceable. The torque-producing device applies a torque to the shaft to wind the flexible restraint member onto the shaft or winding member.
    • 患者支架包括患者保持装置,包括框架,可旋转轴,扭矩产生装置和柔性约束构件。 轴具有从框架延伸的悬臂部分,并在悬臂部分可变地容纳柔性约束件。 可选地,卷绕构件可释放地联接到轴的悬臂部分以接收柔性约束构件。 绕线构件相对于轴不能旋转,并且易于拆卸和更换。 扭矩产生装置向轴施加扭矩以将柔性约束件卷绕到轴或卷绕构件上。

    • A hospital bed has an articulated patient support surface with four air outlet housings mounted thereon at spaced locations. An air supply arrangement supplies temperature-controlled air to an air outlet opening in each of the housings. Associated with each housing is an elongate tubular fabric diffusion member having an O-ring which encircles one end thereof and is removably received in a circumferential groove in the air outlet opening. Each diffusion member can be tucked completely into its housing when not in use. Each housing has a cap movable between open and closed positions with respect to the air outlet opening, and an arrangement yieldably urging the cap toward its closed position. A valve arrangement is provided below two of the housings in order to automatically discharge fluids which happen to enter the air supply system through the air outlet openings. In a variation, two of the elongate diffusion members can be replaced with an inflatable underlay or overlay having two inlet sleeves with O-rings which are each releasably coupled to a respective one of the air outlet devices.
    • 医院病床具​​有铰接的患者支撑表面,在间隔开的位置处安装有四个出气口壳体。 空气供应装置将温度控制的空气供应到每个壳体中的出气口。 与每个壳体相关联的是细长的管状织物扩散构件,其具有围绕其一端的O形环,并且可移除地容纳在空气出口开口中的周向凹槽中。 当不使用时,每个扩散构件可以完全卷起到其外壳中。 每个壳体具有能够相对于空气出口开口在打开和关闭位置之间移动的盖子,以及可靠地将盖子推向其关闭位置的装置。 在两个壳体的两个下方设置阀装置,以便自动排出通过出气口进入供气系统的流体。 在一个变型中,两个细长漫射构件可以用可膨胀的底层或覆盖层代替,其具有两个具有O形环的入口套筒,每个入口套管可释放地联接到相应的一个空气出口装置。
