    摘要： A two-component elastomeric enclosure surrounding a mechanical device can effectively attenuate the noise and vibration associated with the device. The outer shell of the enclosure comprises a castable polyurethane elastomer, while the inner shell of the enclosure comprises polymeric foam. The inner foam layer of the enclosure can contact both vertical and horizontal surfaces of the enclosed device in order to immobilize it within the enclosure, and to enhance the dampening effect of the enclosure on acoustic and mechanical vibrations. The enclosure can act as a vertical and horizontal supporting structure for the enclosed mechanical device. The enclosure may in turn be fastenable to a housing or frame member via relatively stiff elastomeric bushings, pads or mounts, in order to further reduce the transmission of vibrations originating from the mechanical device. The enclosure can be molded in a two-stage pour-molding process using a cavity mold and two forming dies—one for each layer of the enclosure. The second stage of the molding process allows the inner foam layer to bond to the outer shell of the enclosure during the curing process, and to have inner dimensions that can make close contact with pre-determined portions of the device for which the enclosure is being produced. Highly customized cavity molds and forming dies can be created using rapid manufacturing or prototyping techniques.

    摘要翻译： 围绕机械装置的双组分弹性体外壳可以有效地衰减与装置相关的噪声和振动。 外壳的外壳包括可浇铸聚氨酯弹性体，而外壳的内壳包括聚合物泡沫。 外壳的内泡沫层可以接触封闭装置的垂直和水平表面，以便将其固定在外壳内，并且增强外壳在声学和机械振动上的阻尼作用。 外壳可用作封闭式机械装置的垂直和水平支撑结构。 外壳可以通过相对刚性的弹性衬套，衬垫或安装座而可以紧固到壳体或框架构件，以便进一步减少源自机械装置的振动的传递。 外壳可以使用腔模和两个成形模 - 在外壳的每一层的两阶段浇铸 - 成型工艺中模制。 模制过程的第二阶段允许内部泡沫层在固化过程中结合到外壳的外壳，并且具有内部尺寸，其可以与外壳的外壳的预定部分紧密接触 生产。 可以使用快速制造或原型技术创建高度定制的模腔和成型模具。

    摘要： The present invention generally relates to occluders and, in particular, to occluders for use in medical infusion systems. In one aspect, the occluder contains one or more tubes through which fluid can flow, and the occluder can be automatically controlled to allow or at least partially prevent fluid flow. In some cases, the occluder may be constructed and arranged to fail (e.g., due to loss of power) in a “closed” position, i.e., a position that at least partially prevents fluid flow. In addition, in one embodiment, the occluder may be manually overridden, even when in a failed state, by a user. For instance, in the event of a power failure, a user may be able to manually override the occluder to remove tubing from the occluder. Such occluders may find use, for example, in medical devices such as hemodialysis machines, medical infusion pumps, plasmapheresis devices, and the like.
