System and Method of Monitoring Blood Leaks During Hemodialysis Therapy Employing Wireless

摘要

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. 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 includes, or is coupled to, a wireless receiver having two or more antennas. Signals received at the two or more antennas are decoded at the wireless receiver. If decoded signals indicate a detected wetness, the hemodialysis machine is caused to halt blood flow in and out of the machine and generate an alarm.

1. A system comprising:
a wetness sensing device configured to wirelessly transmit information associated with an absence of a liquid or a presence of a liquid; and a hemodialysis machine comprising:
a first antenna in communication with a first receiver and a second antenna in communication with a second receiver, the first antenna and the second antenna being configured to:
simultaneously wirelessly receive the information; andsend the information to the first receiver and the second receiver, respectively;wherein the first receiver is configured to generate a first digital signal based on the information and the second receiver is configured to generate a second digital signal based on the information; anda processor configured to:
receive the first digital signal and the second digital signal;generate a first corrected digital signal based at least in part on the first digital signal, the first corrected signal representing an absence of a liquid or a presence of a liquid; andgenerate a second corrected digital signal based at least in part on the second digital signal, the second corrected signal representing an absence of a liquid or a presence of a liquid.
