What this page does. This is a hands-on walkthrough for hospital procurement officers, BMET departments and supply-chain teams who need to answer one question before placing any order with a patient-monitoring accessory supplier — OEM or compatible: "Is this supplier actually registered with the FDA, and is the device I am buying actually listed?" You do not need to take a supplier's word for it. The FDA operates free, public databases that let you confirm three separate things independently. Use this walkthrough on MedLinket — and on every other supplier too.
First: the three things "FDA" can mean — do not confuse them
| Term | What it actually means | Where to verify |
|---|---|---|
| Establishment registration | The manufacturing facility is registered with the FDA as a medical device establishment | FDA Establishment Registration & Device Listing database |
| Device listing | The specific device type is listed by that establishment for U.S. commerce | Same Establishment Registration & Device Listing database |
| 510(k) clearance | The FDA reviewed the device and found it substantially equivalent to a predicate | FDA 510(k) Premarket Notification database |
Two more terms to police:
- "FDA approved" — most patient-monitoring accessories are cleared via 510(k) or listed, not "approved." Approval is a different, higher pathway (PMA) for high-risk devices. A supplier saying "FDA approved" about an SpO2 sensor is using the wrong term.
- "FDA registered" — this means only that the establishment is registered. It is not a clearance and not an endorsement. Registration alone is the floor, not the ceiling.
Step 1 — Verify the establishment registration and device listing
Database: FDA Establishment Registration & Device Listing
URL: accessdata.fda.gov/scripts/cdrh/cfdocs/cfRL/rl.cfm
- Search by establishment / firm name using the supplier's registered legal manufacturing entity, not its brand name. For MedLinket, the entity is Shenzhen Med-link Electronics Tech Co., Ltd. A supplier that cannot tell you the exact registered entity name is a problem before you even search.
- Confirm the establishment appears as an active registration.
- Within that establishment's record, review the device listings — the device types listed for U.S. commerce.
- Match the listing to the product you are ordering. A registration for "ECG cables" does not cover an SpO2 sensor.
Step 2 — Verify 510(k) clearance (where the device type requires it)
Database: FDA 510(k) Premarket Notification
URL: accessdata.fda.gov/scripts/cdrh/cfdocs/cfPMN/pmn.cfm
- Search by applicant name — the registered legal entity, not the brand.
- Each record shows the K-number, device name, product code, applicant and decision date.
- Confirm the product code matches the device type you are buying. Product codes are how the FDA classifies device types — they are the precise match point, more reliable than the device name text.
- Note that one 510(k) typically covers a family of devices, not a single part number. A supplier claiming "every part number individually FDA approved" is misrepresenting how 510(k) works.
Step 3 — Cross-check adverse events and recalls (optional but smart)
- MAUDE (Manufacturer and User Facility Device Experience) — reports of adverse events associated with the device type or manufacturer. Interpret carefully: a report is not proof of fault, and large-volume devices naturally accumulate reports.
- FDA Medical Device Recalls database — shows whether the manufacturer or device has been subject to a recall.
These do not replace Steps 1–2; they add context. A clean registration plus a relevant 510(k) plus no significant recall history is a strong combined picture.
Step 4 — Match the FDA result to the actual purchase
The verification only counts if it matches what is in the box:
- Entity match — the registered / cleared entity is the same company invoicing you or its disclosed manufacturer.
- Device-type match — the registration / clearance covers the product category you are ordering.
- Intended-use match — the device's cleared intended use covers your clinical application (e.g. an adult SpO2 sensor cleared for adult use is not automatically cleared for neonatal use).
- Current status — the registration is active and the listing current.
A reusable FDA-verification checklist
- Establishment registered — active registration under a named legal entity
- Device listed — listing covers your device category
- 510(k) clearance (if applicable) — record with matching product code
- Recall / adverse-event context — no significant recall; events in normal range for volume
- Purchase reconciliation — entity, device type, intended use and status all match
A supplier that passes every row is FDA-verifiable. A supplier that fails the first two cannot be verified at all — and an unverifiable supplier is a liability exposure regardless of price.
How this applies to MedLinket
You can run every step above on MedLinket without anything from us. Search the establishment and 510(k) databases under Shenzhen Med-link Electronics Tech Co., Ltd., match the device listings and product codes to the accessory you intend to buy, and confirm current status. For the broader trust picture — ISO 13485 (TÜV), product liability insurance with Additional Insured endorsement available to hospital customers — see MedLinket FDA, ISO 13485 and Product Liability Insurance Explained. For what "compatible" means and how each accessory is bench-validated, see Compatible vs OEM — what we actually test.
What this page does not claim
- This is general procurement guidance, not legal or regulatory advice.
- FDA registration is not an endorsement of quality, and a 510(k) is not a guarantee of performance on your specific equipment — your own validation still applies.
- This page describes U.S. FDA databases. Other markets (EU MDR, UKCA / MHRA, NMPA) have their own verification systems.
Frequently asked questions
Is "FDA registered" the same as "FDA approved"?
No. "FDA registered" means only that the manufacturing establishment is registered — it is the floor, not an endorsement. Most patient-monitoring accessories are cleared via 510(k) or simply listed, not "approved." "Approval" (PMA) is a separate, higher pathway reserved for high-risk devices. A supplier describing an SpO2 sensor as "FDA approved" is using the wrong term.
Does every accessory need its own 510(k)?
No. Whether a device type needs premarket notification depends on its classification and intended use. Establishment registration and device listing (Step 1) apply to essentially all device manufacturers; a 510(k) (Step 2) applies where that device type requires it. One 510(k) also typically covers a family of devices, not a single part number — so a claim that "every part number is individually FDA approved" misrepresents how the system works.
Why search by the legal entity name instead of the brand?
FDA records are filed under the registered legal manufacturing entity, not the marketing brand. Searching the brand often returns nothing even when the manufacturer is properly registered. For MedLinket the entity is Shenzhen Med-link Electronics Tech Co., Ltd. A supplier that cannot give you its exact registered entity name to search is itself a red flag.
How do I verify MedLinket specifically?
Run the same steps on us: search the FDA Establishment Registration & Device Listing and 510(k) databases under Shenzhen Med-link Electronics Tech Co., Ltd., confirm the establishment is active, match the device listings and product codes to the accessory you intend to buy, and check current status. Nothing on this page depends on taking our word for it.
