  • Patent number: 9121411
    Abstract: A motor-driven compressor includes a compression mechanism compressing and discharging fluid, an electric motor driving the compression mechanism, a drive circuit controlling the electric motor, a drive circuit chamber accommodating the drive circuit and a hermetic sealing inspection port that allows the drive circuit chamber to be in communication with the outside thereof. The hermetic sealing inspection port includes a valve opening and closing the hermetic sealing inspection port. The drive circuit chamber can be pressurized or depressurized through the hermetic sealing inspection port. The hermetic sealing inspection is conducted by connecting an outside fluid machine to the hermetic sealing inspection port through a detachable tube. The fluid machine is operated so as to depressurize or pressurize the drive circuit chamber through the hermetic sealing inspection port. The pressure in the drive circuit chamber is measured by a pressure meter provided in the tube.

  • Patent number: 9022969
    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the one or more lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.
