A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. This fluid transport mechanism generally aids in reducing wound maceration by removing excess fluid, and potentially even bacteria, and is carried out without loss of physical integrity of the wound care device itself. The absorbent material also is not subject to shifting of the absorbent gelling particles during or after swelling by fluids. The flat container has connecting holes through which adjacent cells communicate and an inlet hole for the working fluid to be poured from outside. Thus, a manufacturing process of the display device is simplified and a manufacturing process efficiency of the display device increases, thereby reducing a manufacturing cost. The locking mechanism may define a handle for supporting the device.
