Abstract: Pump assisted vacuum therapy impotence treatment apparatus may be provided in either electric or manually operated embodiments. The axis of a pump housing affixed to a vacuum chamber via an elastomeric coupler is at an angle to the vacuum chamber axis, and turned towards a user's torso to be drawn into the user's body for better vacuum sealing. The pump cylinder of a manual embodiment has an enlarged annular rest area for receiving a resilient skirt around the piston head during nonuse of the pump. This prevents compression set of the resilient skirt, for more reliable subsequent use of the pump. The vacuum chamber is tapered and transitions from a relatively smaller round end for receipt of a male sex organ to a relatively larger oval shaped end for bayonet mounting on the resilient coupler. A pair of sizing inserts adjusts the vacuum chamber end which receives the male sex organ.

Abstract: A ring loader device is used for expanding an elastic cincture band prior to application to a user's male sex organ for cincturing an engorged condition thereof as a treatment for impotence. A cone component has a conical shaped pyramid with vertical grooves. A corresponding dome component has matable ribs which are received in the cone grooves. The ribs enter the grooves and align the cone and dome as they are matably pressed together. As a prior step, a suitable elastic ring is placed over the tapered smaller end of the cone component, and becomes expanded against the cone outer surface as the dome is pressed onto the cone. The cone may include particular surface contours for corresponding receipt of inside diameter features of the elastic ring, such as a urethra channel or radially inward points for added cincturing pressure. The cone and dome arrangement may be used to expand and align an elastic ring onto a transfer collar, or directly onto the outside diameter of a vacuum chamber.
