  • Patent number: 8851866
    Abstract: Embodiments are described for engaging a pumping cartridge with a pump drive. In certain embodiments, the cartridge, including a cylinder and a movable piston assembly, is initially assembled or subsequently positioned so that the distance between the attachment point on the piston assembly for coupling to a drive assembly, and a reference point on the cylinder, is greater than the maximal distance that will be encountered during normal oscillation of the piston during use. The cartridge, in certain embodiments, may be pressed into a drive assembly that immobilizes the cartridge and couples the piston assembly to the driveshaft. In certain embodiments, when the cartridge is fully inserted into the drive assembly, the piston is pressed into the cylinder sufficiently to establish a selected distance so that the piston shaft is in the proper position to engage with a coupling mechanism carried on the driveshaft.

  • Patent number: 7951107
    Abstract: A method and apparatus are provided for quickly connecting a handpiece to a pressurized fluid source. A hollow tube on the handpiece is inserted through an aperture in an annular gasket which is held in a chamber in a body. On application of pressurized fluid to the body, the gasket is pressed against the walls of the chamber, and against the tube, thereby channeling the pressurized fluid through the hollow tube. The handpiece is retained in connection with the body by a releasable connector, such as a latch. The handpiece can be removed and replaced by releasing and remaking the connection.
