    • A pressure pad (1) has two sets of cells (11, 12) with a sensor pad (8) positioned under the pad (1). During inflation, part of the flow goes to the sensor pad (8) to exhaust and the rest fills the cells (11 or 12). Any change in patient position/weight causing a change in airflow in tube (10) will alter the differential pressure measured at the pressure transducer (16). Based on this feedback the microprocessor directly controls the power level to the pump (6) thus adjusting the airflow to the cells to prevent bottoming or to rung at a minimum pressure. The pressure pad (1) is segmented into a heel section, upper leg section, torso section, and a head section. The heel, head and upper leg sections are maintained at a lower pressure P1 and the torso section at a higher pressure P2. A control module (50) to control the flow in the segments is provided inside the pressure pad (1). The pressure pad (1) can be an alternating or static pad.
    • 压力垫(1)具有两组带有位于垫(1)下方的传感器垫(8)的单元(11,12)。 在充气过程中,部分流体流向传感器垫(8)排出,其余部分充满电池(11或12)。 导致管(10)中的气流变化的患者位置/重量的任何变化将改变在压力传感器(16)处测量的压差。 基于这种反馈,微处理器直接控制泵(6)的功率水平,从而调节流向单元的气流以防止触底或在最小压力下流动。 压垫(1)分成后跟部分,大腿部分,躯干部分和头部分。 脚跟,头部和大腿部分保持在较低的压力P1,躯干部分保持在较高的压力P2。 在压力垫(1)内部设置有控制模块(50),用于控制区段中的流动。 压垫(1)可以是交替的或静态的垫。
