Patent granted for a medical device with grounding system
A recently granted patent (Publication Number: US11771808B2) describes a medical device with a unique power supply and treatment system configuration. The device includes a power supply with a power supply cable that has a first ground wire connected to a first ground prong. The treatment system, which is used for medical treatment of patients, includes a grounding cable with a second ground wire connected to a second ground prong.
The patent claims that the first ground prong and wire are electrically isolated from the second ground prong and wire. Additionally, the power supply cable and grounding cable are connected to a combined plug that can be plugged into an AC power outlet. This combined plug includes a line prong, a neutral prong, the first ground prong, and the second ground prong.
The first ground prong and wire are also electrically isolated from the second ground prong and wire. The patent further describes that the first ground prong and wire are in electrical communication with the second ground prong and wire behind a wall plate of an AC power outlet when the combined plug is plugged in.
The medical device also includes a handle on the combined plug to facilitate simultaneous connection of the power supply cable and grounding cable to an AC power outlet. The first ground wire and second ground wire do not share a common insulation, and they form separate grounding connections with their respective ground prongs.
The patent claims that the medical device complies with one or more requirements specified by a standards organization, specifically the International Electrotechnical Commission (IEC) and the requirements specified in IEC 60364-7-710, when the grounding connections are connected to different AC sockets of an AC power outlet.
The device is described as a hemodialysis ("HD") machine, and the power supply cable and grounding cable connect to separate locations on the housing of the device. Additionally, the device may include an adapter that can be used to connect the power supply cable and grounding cable to an AC power outlet.
Overall, this patent describes a medical device with a unique power supply and treatment system configuration that ensures proper grounding and compliance with relevant standards. The device is specifically designed for use in hemodialysis treatment and may include a hydraulic system as part of the treatment system.
