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.

A manually manipulable pump unit for effecting a pulsating flow of liquid to a point of treatment in an operating or other surgically related room, the combination comprising: a housing having an elongated opening therethrough for the reception therethrough of a resilient flexible tubing; a hollow pedestal upstanding from said housing and a generally elongated tubular handle fixed to the upper end of said pedestal and having its centerline lying in a plane generally parallel with the centerline of the opening in said housing; a rotary prime mover within said handle and link means within said pedestal driven by said motor for effecting reciprocal motion in a direction generally perpendicular to the centerline of said opening; a plate within said opening engageable against tubing within said opening and caused to move toward and away from the opposite side of said opening by said link means in response to actuation of said motor; whereby said tubing will be ultimately squeezed and released for effecting a pulsating flow through said tubing in the manner of a peristaltic pump.
