摘要： A fluidization level sensor and controller for use in a fluidized patient support surface has a controller coupled to a sensor and a compressor. The patient support surface contains a mass of granular particles housed in frame walls and supported by a diffuser. The compressor forces a fluid, typically air, into a plenum chamber and through the diffuser. The fluid flows through the mass of granular particles, causing the mass of granular particles to fluidize, and exits through a fluid permeable sheet. The fluidization level sensor produces an output signal proportional to the fluidization level of the mass of granular particles, and provides this output signal to the controller. The controller generates a compressor control signal in response to the output of fluidization level sensor, which in turn adjusts the compressor to maintain a substantially constant fluidization level.

摘要翻译： 用于流化患者支撑表面的流化度传感器和控制器具有耦合到传感器和压缩机的控制器。 患者支撑表面包含容纳在框架壁中并由扩散器支撑的大量颗粒状颗粒。 压缩机迫使流体（通常为空气）进入增压室并通过扩散器。 流体流过颗粒状颗粒，导致粒状颗粒物质流动，并通过流体可渗透的片材排出。 流化液位传感器产生与颗粒物质质量流化度成比例的输出信号，并将该输出信号提供给控制器。 控制器响应于流化液位传感器的输出产生压缩机控制信号，流量级传感器进而调节压缩机以保持基本恒定的流化水平。

摘要： A proportional flow control valve is provided for use with low air loss patient support systems. The valve includes a valve housing having an inlet and an outlet defined therein with a valve passage defined through the housing between the inlet and outlet. A chamber is defined in the housing, the chamber further including a nipple cavity defined in the bottom thereof and a cam stop extending from the bottom into the chamber. A valve spool is rotatably disposed within the chamber. The valve spool includes an alignment nipple fitting into the nipple cavity and a cam defined on the bottom thereof through a predetermined rotational arc. The cam and cam stop cooperate to limit the rotational arc of the valve spool within the chamber. A proportional flow control groove is defined in the valve spool. The flow control groove establishes linear air flow through the valve depending on the angular displacement of the spool within the chamber. A motor is provided mounted to the housing to rotate the valve spool within the chamber and, preferably, a torque limiting clutch is disposed between the motor and valve spool. The valve spool further includes a friction reducing substance coated thereon or impregnated therein, such as teflon or the like, to reduce binding of the valve spool within the chamber.

摘要： A method for turning a bed ridden patient uses a low air loss patient support system that includes a plurality of identical multi-chambered inflatable sacks. A restrictive flow hole connects two adjacent chambers disposed predominately to one side of the centerline of the sack, and each side is separately pressurizable under the control of a microprocess and a plurality of pressure control valves with pressure transducers and a plurality of flow diverter valves for switching between different modes of configuring the manner in which the sacks are pressurized. The support system effects a method of rotating or tilting the patient that depressurizes one side of the sacks while increasing the pressurization of the opposite side of the sacks. The end chamber of the depresurizing side of the sacks remains inflated while the intermediate chamber of the depressurizing side of the sacks becomes progressively deflated during depressurization to permit the end chamber to restrain the patient from sliding off the sacks during tilting.
