What Is the Draeger 1275275 Compatible NIBP Air Hose?

The Draeger 1275275 compatible NIBP air hose is a reusable, aftermarket extension hose that connects a single-tube blood pressure cuff to the monitor’s non-invasive blood pressure port. During each measurement, the monitor inflates the cuff through this hose and reads cuff pressure oscillations back through it, so an airtight, correctly fitted hose is essential for accurate mmHg readings. It is a compatible replacement, not an original Draeger part, and it is built to the same fit, form, and function as the OEM 1275275 hose.

Compatible Monitor Models

This compatible hose is confirmed for use with the Draeger Infinity Delta, Infinity Gamma, Infinity Kappa, and Infinity Vista monitors, and with the SC 6000, SC 7000, SC 8000, and SC 9000. All of these share the Draeger single-tube NIBP port. The hose pairs with adult and pediatric single-tube cuffs that use a bayonet-style connector. Neonatal cuffs and dual-tube cuffs need a different hose.

Design and Construction

The hose runs 12 ft (3.7 m), a longer length suited to ICU and OR setups where the monitor sits well away from the patient or the cuff must reach across a bed or table. The monitor end has a Draeger mono plug built from copper and nylon for a secure, leak-free seat in the NIBP port. The cuff end has a metal female bayonet quick-disconnect that locks onto single-tube bayonet cuffs with a push-and-twist motion and resists accidental disconnection during patient movement. The PVC tubing has an inner diameter of about 0.12 in (3.1 mm) and an outer diameter of about 0.23 in (5.8 mm), which keeps airflow consistent while resisting kinks. The hose is latex-free, non-sterile, rated for adult and pediatric use, weighs about 0.7 lbs, and ships one per bag.

When to Replace Your Draeger NIBP Air Hose

NIBP hoses fail mostly through air leaks, which show up as slow or repeated cuff inflation, “cuff leak” or “measurement failed” alarms, readings that time out, or pressures that don’t match a manual check. Other signs include cracked or stiffened tubing near either connector, a bayonet fitting that no longer locks or sits loosely on the cuff, damaged O-rings, and a mono plug that wobbles in the monitor port. A quick leak test with a known-good cuff and simulator will confirm whether the hose is the cause. Replacing a worn hose is a low-cost fix that often clears alarms without taking the monitor out of service.
