According to at least one example embodiment, a system of monitoring blood leaks during hemodialysis therapy includes a wetness sensing device and a hemodialysis machine (120). The wetness sensing device is configured to transmit information wirelessly, the information being indicative of an absence of a liquid or a presence of a liquid. The hemodialysis machine (120) includes, or is coupled to, a wireless receiver having two or more antennas (132a, 132b). Signals received at the two or more antennas (132a, 132b) are decoded at the wireless receiver. If decoded signals indicate a detected wetness, the hemodialysis machine (120) is caused to halt blood flow in and out of the machine and generate an alarm. |
