<p>A disposable device (10) for controlling the rate of suction to and from a bodily organ, such as the stomach, during a lavage procedure that involves the use of a movable controller (32) that slides back and fort h over an opening (30) in the main body (18) of the device. The interior opening of the device which is placed in a flowline (12) that exten ds from the stomach upstream to a downstream (22) collection vessel has a tapered flow path (26) that allows for the uninterrupted flow o f pill fragments or stomach contents through the flowline. A lateral flow path (28) that extends from an opening (30) in the exterior of the main body to the main flow path (26) enables an operator to vary the suction pressure to or from the patient by varying the size of the exterior opening through the use of the movable controller.</p> |
