摘要：
The invention is provided a carrier structure for dynamically adjusting pressure distribution, which comprises a plurality of sensing units and gasbags, an air-pressure unit and a control circuit. The sensing units set in the carrier sense the pressure made by a body at one of a plurality of pressed points upon the carrier to generate a plurality of sensing signals. The gasbags set in the carrier are arranged correspond to the sensing units and adjusted for changing the pressure supported by the one pressed point. The air-pressure unit adjusts the air pressure of the gasbags for changing the pressure supported by the one pressed point in response to a control signal. The control circuit coupled to the sensing units and the air-pressure unit signals the control signal to the air-pressure unit in response to the sensing signal. Thereby, the invention is provided to prevent the body with the pressure ulcer.本發明為一種動態調整壓力分佈之載體結構,其包含複數感測單元、複數氣囊、一氣壓驅動部及一控制電路。複數感測單元設置於載體內用以感測一人體位於載體之至少一受力點的壓力或剪力而產生複數量測訊號;該些氣囊設置於載體內並對應該些感測單元排列,該些氣囊用以調整人體位於載體之該受力點的壓力;氣壓驅動部連接該些氣囊並依據一控制訊號而調整該些氣囊的氣壓以調整該受力點的壓力;控制電路耦接該些感測單元與氣壓驅動部並依據該些量測訊號而產生並傳送控制訊號至氣壓驅動部。如此,本發明改變人體位於載體之受力點的壓力而避免人體產生壓瘡。10‧‧‧墊子21‧‧‧感測單元23‧‧‧氣囊25‧‧‧氣壓驅動部27‧‧‧控制電路29‧‧‧儲存單元VAIR‧‧‧氣壓驅動訊號VC‧‧‧控制訊號VIN‧‧‧外部控制訊號VM‧‧‧量測訊號VTH-P‧‧‧壓力門檻訊號VTH-PT‧‧‧壓力門檻時間訊號VTH-S‧‧‧剪力門檻訊號VTH-ST‧‧‧剪力門檻次數訊號
