There appeared in the December 1935 issue of International Clinics1 an excellent article on the treatment of acute empyema in which attention was directed to the value of "tidal irrigation" in promoting early complete closure of an empyema cavity.
The procedure was accomplished by a series of two or more bottles so arranged as to hydrostatics that alternate irrigation and mild suction would be applied to the pleural cavity. The principle seemed excellent, but the recommended apparatus seemed quite intricate.
The apparatus here described is offered as a simplified method of carrying out tidal irrigations and has been found to function in an excellent manner.
Irrigating fluid is supplied from a reservoir through a drip, the flow of which is regulated by a screw clamp. As the fluid drips into the irrigating system, it flows into the pleural cavity and into the bottle as illustrated. This bottle carries an
