The new Ohio Medical 7700 series brass medical gas flowmeter product line features optional configurations for the new, safer “Second Look” nut and nipple connector. The “Second Look” nut and nipple is made of clear plastic as opposed to green for Medical O2, and yellow for Medical Air. The “Second Look” clear plastic nut and nipple connector helps remind the clinician to take a second look ensuring they are attaching the nut and nipple connector to the appropriate medical gas flowmeter. Ohio Medical has also added a white background to the flowmeter tube to enhance visibility of the flow indicator ball. The new 7700 series is available in 0-1, 0-31/2, and 0-15 liter/minute configurations for medical O2 and medical air that can be used in Neonatal, Pediatric and Adult applications.
