    • A patient support system having multiple patient support layers for reducing and preventing the development of bed sores in bedridden patients. A top patient support surface is provided by an anti-shear cover layer. The anti-shear cover layer being operable to reduce lateral shear forces experienced by a patient moving across the patient support surface. One or more fluid pouches or bladders are provided to form a fluid bladder layer for reducing normal pressures and forces experienced by the patient. The fluid bladder layer being releasably or integrally secured to the top surface of an inflatable air mattress. Means are provided operable to secure the anti-shear cover layer and fluid bladder layer in overlapping relation to the inflatable air mattress. Also provided is a means for adjusting the temperature of the fluid contained within the fluid bladder layer.
    • 一种具有多个患者支撑层的患者支撑系统,用于减少和预防卧床患者的床褥疮的发展。 顶部患者支撑表面由抗剪切覆盖层提供。 抗剪切覆盖层可操作以减少患者在患者支撑表面上移动所经受的横向剪切力。 提供一个或多个流体袋或囊以形成流体囊层,用于减少患者经历的正常压力和力。 流体囊层可释放地或一体地固定到可充气空气床垫的顶表面。 提供可操作以将抗剪覆层和流体囊层与充气空气床垫重叠的方式固定的装置。 还提供了一种用于调节包含在流体囊层内的流体的温度的装置。

    • Methods and apparatus for preventing bed sores in a bedridden patient. A patient-supporting low air loss bed includes a frame, a first set of air bags for supporting a patient thereon mounted transversely on the frame, and a second set of substantially rectangular air bags for supporting a patient thereon mounted substantially transversely on the frame, and all of the air bags are connected to a gas source. The configuration of the air bags is such that when the first set of air bags is inflated, the patient supported thereon in moved toward the first side of the frame of the low air loss bed and when the second set of air bags is inflated while the first set of air bags is deflated, the patient is moved toward the second side of the low air loss bed. The configuration of the air bags also retains the patient on the top surface of the air bags when the patient is rolled in one direction or the other.The operator of the low air loss bed defines the pressures in individual air bags corresponding to each of three positions to which the patient is rotated. The pressures are maintained by a feedback control system which actuates valves connecting the gas source to separate sets of air bags. The three positions to be sequentially attained thereby causing controlled oscillation of the patient from one side of the bed frame to the other. Because each rotation position corresponds to operator defined pressures, the oscillation is customized for individuals of different body weights.
    • 卧床病人防止褥疮的方法和装置。 患者支持的低空气损失床包括框架,用于支撑横向于框架的患者的第一组气囊和用于支撑患者的第二组大致矩形的气囊,所述第一组基本上矩形的气囊基本上横向安装在框架上, 并且所有气囊都连接到气源。 气囊的构造使得当第一组气囊膨胀时,支撑在其上的患者向低空气损失床的框架的第一侧移动,并且当第二组气囊膨胀时 第一组气囊被放气,患者向低空气流失床的第二侧移动。 当患者沿一个方向或另一个方向滚动时,气囊的构造还将患者保持在气囊的顶表面上。 低空气损失床的操作者限定了与患者旋转的三个位置中的每一个相对应的各个气囊中的压力。 压力由反馈控制系统维持,反馈控制系统致动将气体源连接到分离的气囊组的阀。 三个位置被顺序地获得,从而使得患者从床架的一侧到另一侧受到可控振动。 因为每个旋转位置对应于操作员定义的压力,因此针对不同体重的个体定制振动。

    • An air sac for use on a low air loss bed. The air sac is provided with a releasable connector for retaining the air sac to the low air loss bed and with a nipple for receiving air from a gas supply source to inflate the air sac. The air sac is also provided with a cutout which allows the patient to be rolled toward one end of the air sac when the air sac is inflated. A pillar is provided on the end of the air sac toward which the patient is rolled when the air sac is inflated to retain the patient on the air sac. The air sacs are arranged in sets with every other sac mounted to the frame of the low air loss bed in alternating arrangement whereby the patient is rolled first in one direction when the air sacs of one set are inflated and then back in the other direction when the air sacs in the first set are deflated and the air sacs in the second set are inflated.
    • 用于低空气损失床的气囊。 气囊设置有可释放的连接器,用于将气囊保持在低空气损失床上,并具有用于接收来自气体供应源的空气以使气囊膨胀的接头。 气囊还设置有切口,当空气囊膨胀时,允许患者朝向气囊的一端滚动。 当气囊被充气以将患者保持在气囊上时,在气囊的端部上设置有一个支柱,该气囊向病人滚动。 气囊被布置成一套,每隔一个囊以交替布置的方式安装在低空气损失床的框架上,由此当一组气囊膨胀然后在另一方向上向后方向时,患者首先在一个方向上滚动, 第一组中的气囊被放气,并且第二组中的气囊膨胀。
