Abstract
Therapeutic device for providing intermittent flow of liquid to an incision or wound. A handpiece containing a suitable motor is supportingly connected to a pump unit containing a reciprocable plate. Operating means connect said motor to said plate for effecting reciprocation thereof in a direction perpendicular to the plane of the plate. A resiliently flexible tube extends through said pumping unit and adjacent said plate and is subjected to peristaltic pumping action as said plate reciprocates, thereby urging liquid within said tube to move intermittently therethrough. One end of the tube is connected to a source of liquid and the other end is connected to a suitable nozzle for directing such liquid into the wound or incision.
