Abstract: The present invention is directed to a harness system for supporting on a wearer, a portable chemotherapy treatment dispenser. The harness system includes a harness arranged and configured to removably surround a portion of the wearer. A container support means is mounted on the harness at a first location and is adapted to receive and hold a container of chemotherapy medication. A pump holding means is mounted on the harness at a second location and is adapted to receive and hold a pump. The harness may comprise a belt arranged and configured to be worn approximately about the wearer's waist. A shoulder strap may also be provided as part of the harness. The belt portion of the harness may be a brace, such as a back brace.

Abstract: A disconnect signal (e.g. 130 volts D.C.) is applied at the telephone central office to the tip and/or ring lines. A latching relay adjacent to the subscriber equipment operates directly responsive to the disconnect signal, i.e. without delay normally caused by capacitive or voltage buildup, to disconnect the line between the tip and/or ring lines to which the signal has been applied and the subscriber equipment. The relay simultaneously connects the signal to ground through a relatively large resistance to identify or confirm to the central office that the switching action has occurred, which in turn is indicative of line continuity. The relay also operates in a similar manner responsive to a reverse polarity signal (e.g. the re-establishment of the normal line voltage of -48 volts D.C.) to re-establish a normal operative condition.
