    • A mattress has a sensor pad affixed on a top surface thereof. The sensor pad has (i) a matrix array of plural pressure sensors, (ii) plural row conductors, and (iii) plural column conductors. Each intersecting row and column conductor provides an electrical signal from a corresponding sensor when pressure is applied thereto. The sensor pad has plural through-holes therein disposed between the plural row conductors the plural column conductors, respectively. Preferably, at least one patient-mounted physiological sensor is configured to provide an output signal corresponding to a patient physiological parameter. An electronic unit is mounted inside the mattress and is configured to receive signals from the sensor pad. The electronic unit has a data storage unit preferably storing (i) patient identification information, (ii) patient physiological information, and (iii) mattress information. A wireless transmitter is coupled to the electronic unit and is configured to wirelessly communicate at least the stored patient physiological information to an off-mattress device.
    • 床垫在其顶表面上固定有传感器垫。 传感器垫具有(i)多个压力传感器的矩阵阵列,(ii)多个行导体和(iii)多个列导体。 当对其施加压力时,每个相交的列和列导体提供来自相应传感器的电信号。 传感器衬垫具有多个通孔,分别设置在多个列导体之间,多个列导体。 优选地,至少一个患者安装的生理传感器被配置为提供对应于患者生理参数的输出信号。 电子单元安装在床垫内部并被配置为从传感器垫接收信号。 电子单元具有数据存储单元,优选地存储(i)患者识别信息,(ii)患者生理信息和(iii)床垫信息。 无线发射器耦合到电子单元,并且被配置为至少将所存储的患者生理信息无线地传送到离床装置。

    • Force or pressure transducer arrays have elastically stretchable electrically conductive polymer threads disposed in parallel rows and columns that contact at intersections thereof a piezoresistive material which has an electrical resistivity which varies inversely with pressure or force exerted thereon to form a matrix array of force or pressure sensor elements. The threads are fixed to a single one or pair of flexible elastically stretchable substrate sheets made of thin sheets of an insulating polymer such as PVC, or for greater elasticity and conformability to irregularly-shaped objects such as human body parts, an elastically stretchable fabric such as LYCRA or SPANDEX. Elastic stretchability of the sensor arrays is optionally enhanced by disposing either or both row and column conductive threads in sinuously curved, serpentine paths rather than straight lines.
    • 力或压力传感器阵列具有弹性拉伸的导电聚合物丝线,其设置成平行的行和列,其在其交点处接触压电材料,该压阻材料具有与施加在其上的压力或力反向变化的电阻率,以形成矩阵阵列的力或压力传感器 元素。 螺纹被固定到由绝缘聚合物如PVC的薄片制成的单个或一对柔性弹性可拉伸基底片上,或者对于诸如人体部位的不规则形状物体,弹性伸缩性织物 作为LYCRA或SPANDEX。 传感器阵列的弹性可拉伸性可选地通过将行和列导电丝布置在弯曲曲线的蛇形路径中而不是直线来增强。
