Quick answer. Nihon Kohden's monitoring portfolio is wide — Life Scope bedside platforms, the BSM transport-capable bedside family, the PVM compact bedside, and the extensive SVM family. Across all of it, three decisions drive accessory selection: the SpO2 connector (14-pin Nihon Kohden native, 9-pin OxiMax when specified with Nellcor-licensed SpO2, or legacy 7-pin OxiSmart); the ECG trunk type (12-pin on most current units, 6-pin on legacy and compact units); and an English-market vs China-market part-number prefix difference on disposable SpO2 sensors. Configuration variance across this portfolio is significant — per-unit confirmation is essential before ordering. Jump to the accessory list by family.

How to identify your Nihon Kohden SpO2 generation
Three ways to confirm:
- Look at the SpO2 connector on the monitor: 14-pin Nihon Kohden native is the original round 14-pin standard; 9-pin OxiMax (Nellcor-licensed) is a 9-pin connector present when the monitor was specified with Nellcor SpO2; 7-pin OxiSmart is the legacy round connector on older BSM and Life Scope units.
- Check the SpO2 sensor cable currently in use — the OEM part number on the label identifies the generation.
- Check the unit's purchase order or biomedical record — Nihon Kohden documents the SpO2 technology on the original quote.
SpO2 accessories by connector generation — the rule
- 14-pin native — the most common connector on Life Scope, BSM, PVM and SVM. MedLinket 14-pin compatible sensors cover reusable direct-connect and short-cable styles plus the full TL-series disposable range below.
- 9-pin OxiMax (Nellcor-licensed) — when Life Scope, BSM or SVM was specified with Nellcor SpO2, the OxiMax algorithm runs on the licensed Nellcor board. MedLinket OxiMax-compatible cables transmit the optical waveform and do not replicate Nellcor's signal processing — the DS-100A-style reusable adult finger clip and the Nellcor family serve these units.
- 7-pin OxiSmart legacy — older Life Scope and early BSM units shipped with the legacy 7-pin OxiSmart standard; confirm the connector per unit and request a configuration review for these.
- 14-pin to 9-pin adapter cables — for a mixed Nihon Kohden fleet that wants to use newer 9-pin sensors on older 14-pin monitors. Two distinct adapters exist — one routing OxiMax technology, one routing NK technology — they look similar but are not interchangeable.
Compatible accessories by family — direct links
Confirm each unit's SpO2 connector generation before ordering sensors (see above), the ECG trunk pin count (12-pin vs 6-pin) and colour code (AHA vs IEC), and the NIBP cuff connector. For anything not listed, browse the full Nihon Kohden compatible accessories collection.

Temperature probes YSI-400
All temperatureNihon Kohden uses YSI-400 thermistor probes. Confirm the monitor-end connector per unit (an adapter may be required) and select the YSI-400 probe by site:
| Product | Site / patient |
|---|---|
| YSI-400 adult skin (409B) | Adult, skin |
| YSI-400 adult eso/rectal | Adult, eso/rectal |
| YSI-400 pediatric skin | Pediatric, skin |
| YSI-400 pediatric eso/rectal | Pediatric, eso/rectal |
Confirm your thermistor standard with the YSI 400 vs YSI 700 compatibility test.
BIS anesthesia-depth & EEG
All anesthesia EEG| Product | Type |
|---|---|
| BISx anesthesia EEG adapter cable | BIS adapter cable |
| 186-0106 EEG sensor | Disposable non-invasive EEG sensor |
| 186-0107 adapter cable | Anesthesia EEG adapter cable |
BIS depth-of-anesthesia interpretation is performed by the BIS algorithm in the host module — MedLinket adapters and sensors transmit the EEG signal and do not replicate or modify BIS signal processing.
EtCO2 & water traps
All EtCO2Nihon Kohden monitors with the EtCO2 option module accept third-party mainstream and sidestream sensors, airway adapters, CO2 nasal cannulas and a waterlock with the appropriate NK-protocol adapter. Confirm the module protocol per unit and browse the EtCO2 collection.
Reading path by clinical scenario
Adult ICU on Life Scope / BSM-6701C (fixed bedside)
5-lead 12-pin ECG trunk plus adult solid-gel electrodes; 14-pin reusable adult finger-clip SpO2 (NK native) or 9-pin OxiMax if Nellcor-licensed; adult-standard reusable NIBP cuff plus dual-tube extension; 1–2 IBP channels with a 12-pin NK-to-Edwards or NK-to-Utah cable; NK skin temperature probe; BIS if the anesthesia-depth option is installed.
Cardiac surgery OR on Life Scope G7 / G9
10-lead diagnostic 12-pin ECG plus diagnostic leadwires plus radiolucent electrodes; 14-pin or 9-pin OxiMax reusable adult finger-clip SpO2; adult-large NIBP cuff; 3–4 IBP channels with closed blood sampling; dual-site temperature; mainstream EtCO2; BIS for anesthesia depth.
ED triage and step-down on BSM-1700 / PVM-2703 / BSM-3562
5-lead 12-pin or 6-pin ECG trunk (per model) plus adult solid-gel electrodes; reusable or disposable SpO2 by turnover; NIBP cuffs in 2–3 sizes per unit; optional temperature probe. IBP and EtCO2 are typically not on these models.
NICU on Life Scope with neonatal module
Neonatal DIN 3-lead trunk plus neonate radiolucent electrodes; 14-pin neonate wrap reusable or neonate adhesive disposable SpO2; neonate NIBP sizes 1–5 with single-tube extension; pediatric / neonate NK-compatible temperature probe; IBP umbilical artery monitoring if needed. Clinical reminder: 2-hourly site rotation and skin inspection are the primary defence against medical-device-related pressure injury (MDRPI) — see the NK neonate / adult SpO2 sensor page for detail.
Transport on SVM-7000 series
Add a 6 m NIBP interconnect tube and a strain-relief-reinforced SpO2 extension cable to the unit's standard configuration, and verify the monitor battery within its service interval.
Common procurement pitfalls
- English vs China-market code mismatch. The same disposable sensor carries different MedLinket part-number prefixes in the two regional catalogues — the product is identical. Confirm which catalogue your sourcing channel uses; when in doubt, photograph the existing product code.
- Ordering a 14-pin sensor for a 9-pin unit, or vice versa. The Nihon Kohden portfolio spans both connector generations. Identify the connector before ordering.
- Confusing the 14-pin-to-9-pin OxiMax adapter with the 14-pin-to-9-pin NK adapter. They look mechanically similar but route different SpO2 technologies. Confirm the SpO2 technology of the source sensor before ordering the adapter.
- Mixing AHA and IEC ECG leadwire colour codes. Standardise the colour code by department.
- Ordering a 12-pin ECG trunk for a compact BSM that has a 6-pin port. Use a model-specific purchase order.
- Treating SVM-series accessories as identical across the family. The SVM models differ — write the exact model name on the purchase order, not "SVM-series accessories."
How to get a configuration review
Whether you run a Life Scope, BSM, PVM, SVM or mixed Nihon Kohden fleet, MedLinket's configuration team will review your inventory. Provide your model list, the SpO2 generation per model, the installed option modules, your disposable transducer brand standard, your sourcing region, and your current accessory inventory. There is no obligation to purchase.
Frequently asked questions
How do I tell which SpO2 connector my Nihon Kohden monitor uses?
Look at the SpO2 connector on the monitor, check the OEM part number on the SpO2 cable currently in use, or check the original purchase order. 14-pin native is the most common; 9-pin OxiMax is present when the monitor was specified with Nellcor SpO2; 7-pin OxiSmart is the legacy connector. Per-unit confirmation is essential because the portfolio spans all of these.
Why do the disposable sensor part numbers differ between catalogues?
MedLinket uses different internal part-number prefixes for Nihon Kohden-compatible disposable sensors in English-market versus China-market documentation. The physical product is identical — only the prefix differs by region. Confirm which catalogue your sourcing channel uses, or photograph the existing product code.
Can I use newer 9-pin sensors on our older 14-pin Life Scope monitors?
Yes, with a 14-pin-to-9-pin adapter cable. Note that two distinct adapters exist — one routes OxiMax technology, one routes NK technology — and they are not interchangeable. Confirm the SpO2 technology of the source sensor before ordering the adapter.
