摘要： A line mount includes a treatment machine having a housing and one or more magnets or ferromagnetic elements mounted thereon, a line holder having at least one complementary one of magnets and ferromagnetic elements such as to cause the line holder to be attachable magnetically to the housing. The one or more magnets or ferromagnetic elements being numbered and arranged to permit the line holder to be supported thereby in multiple positions and orientations relative to the housing.

摘要： A cartridge insertion system includes a chassis supporting a fluid circuit, the chassis having a forward end with key pins projecting from the forward end and a rear end. The system also includes a medical treatment device with a slot opening closed by doors having a major dimension and having key openings spaced apart a same distance as the key pins on the chassis, such that when the chassis is pushed toward the slot opening, the key pins enter the key openings before the forward end meets the doors. The key pins push against latches that hold the door locked shut, so that the doors will not open if a cartridge without key pins is pressed against the door. When a cartridge with key pins is used, the doors unlock and allow the cartridge to be inserted.

摘要： A peristaltic pump actuator includes a rotor element supporting rollers, the rotor element being configured to rotate about a rotor axis and the rollers each being configured to rotate about a roller axis that is parallel to the rotor axis. The rotor element and each of the rollers is constrained such that the rotor element and rollers are able to rotate only about their respective axes. A shoe having a displacement axis perpendicular to the rotor axis is forced against the rollers by an urging element without rotation in any axis. A tube may be placed between the shoe and the rollers.
