What Is the Nihon Kohden YN-921P Compatible Neonatal NIBP Air Hose?

The IPR Medical BPH-ND35-15N-S06 is a compatible aftermarket (not OEM) NIBP air hose that replaces the Nihon Kohden YN-921P. It is a reusable neonatal hose with two tubes and an 11.5 ft (3.5 m) length, and it is used with 1-tube male Luer slip cuffs.

Compatible Monitor Models

Listed equipment for this neonatal hose spans select Nihon Kohden models such as the BSM-1101, BSM-2351, BSM-3500, BSM-4100, BSM-6501, and BSM-8800, as well as Life Scope J, Life Scope TR, Life Scope SVM 7200 Series, and PVM 2700 entries. Certain entries name a monitor together with another Nihon Kohden part, for example BSM-6000 with AY 653P or BSM-5100 with YJ 510P. Use the Compatible Monitor Models table on the Specifications tab to verify your model and configuration before ordering.

Design and Construction

This replacement hose uses a 2-tube (double tube) layout with a Neonate Red Block BP plug and is paired with a 1-tube male Luer slip cuff. It is specified for neonate patients, measures 11.5 ft (3.5 m), and ships one per bag. Since the hose is reusable, it can be cleaned between patients following facility protocol and kept on the unit as long as it passes inspection.

When to Replace Your Neonatal NIBP Air Hose

Pull the hose from service if you find cracked, split, or stiffened tubing, persistent kinks, or a connector that wobbles, leaks, or will not seat. On the monitor, recurring leak alarms, cuffs that are slow to inflate, and NIBP readings that fail or time out are typical warning signs. A side-by-side check with a known-good hose helps biomedical staff confirm the fault before the next patient.

Cross Reference and Interchange Part Numbers

This compatible hose replaces the Nihon Kohden YN-921P and also cross-references to Nihon Kohden S04, S05, and S905. Refer to the Cross Reference / Interchange Part Numbers table on the Specifications tab for the remaining interchange number.
