Boehringer 7702-L Intermittent Suction Regulator

Boehringer Laboratories' 7702-L Intermittent Suction Regulator provides controlled negative pressure from hospital pipeline vacuum systems for operating rooms, intensive care units, recovery areas, bedside care, and GI drainage. It delivers a 0–200 mm Hg full‑scale range with a pin‑stop gauge and 2 mm Hg graduations, and supports both continuous and intermittent suction via a three‑way control valve (off, intermittent, continuous) with an adjustable cycle. The regulator features all‑metal construction with synthetic sapphire coatings on wear surfaces, self‑cleaning ports, and a filter‑protected timing circuit, making it fully serviceable without special tools. Disinfection and sterilization options include Steam, Cidex, EtO, and STERRAD, and it is designed for standard hospital vacuum line connections with available inlets/outlets; note that line vacuum is not available on the patient side for safety. Some listings note that the regulator ships with a vacuum adapter for integration with existing systems.
