An apparatus, intended to be mounted adjacent a patient, which supports an inspection chamber at a predetermined elevation with respect to the patient, the chamber being connected to the patient through an infusion supply tube. A container of intravenous infusion fluid supplies the fluid to the inspection chamber at a predetermined pressure, and at a selected rate, depending on the selection of one of several exit orifices and calculated to maintain the fluid at a predetermined level in the inspection chamber. Fluid level sensors give warning if the fluid level in the inspection tube rises or falls a preselected amount. In one embodiment, the fluid level in the container is maintained at a fixed level above the inspection chamber. In another embodiment, the infusion level is maintained under a predetermined pressure by a regulated pressure fluid.
