Configured w/Chemetron Inlets

The Push-To-Set™ Intermittent Suction Unit (PTS-ISU) exceeds clinical expectations in medical suction procedures, by offering technology breakthroughs plus the quality and simplicity you are accustomed to receiving from Ohio Medical Corporation’s products.  It retains the unique, patented unilogic module which provides a reliable, quiet means of cycling the regulator on and off during intermittent suctioning.  It also offers dual modes to provide the option of an intermittent mode for nasogastric drainage or the new CASS procedure and a continuous mode for tracheal, pharyngeal or surgical suctioning.

The PTS-ISU has an ergonomic design that contains two new exclusive safety features that simplify processes, minimize clinical errors and increases product performance. The patented Push-To-Set™ mechanism automatically establishes a vacuum limit with each vacuum level setting in both continuous and intermittent modes. A unique dual-spring regulator module ensures precision in the critical care range (0-200 mmHg) while also providing unusually fast adjustment (2 turns) up to full wall vacuum for emergency resuscitation procedures.
