What this page does. This page answers the most important question about any compatible-accessory supplier: "Can you prove the regulatory and liability claims you make — and can I verify them without taking your word for it?" It is a trust page, not a marketing page. Three things make a compatible medical accessory supplier safe to buy from: a real regulatory clearance, a real quality-management certification, and real financial backing if something goes wrong. This page explains each of the three — what it means, what it does not mean, and exactly how you verify it yourself.
1. FDA 510(k) — what it means and what it does not
What FDA 510(k) clearance is
A 510(k) is a premarket submission to the U.S. FDA demonstrating that a device is substantially equivalent to a legally marketed predicate device. For a patient-monitoring accessory such as an SpO2 sensor, ECG cable or NIBP cuff, 510(k) clearance means the FDA has reviewed the device and agreed it is as safe and effective as an existing cleared device of the same type.
MedLinket markets compatible patient-monitoring accessories that are listed with the FDA, and a number of MedLinket device types hold FDA 510(k) clearance. The 510(k) pathway is the same regulatory route used by most patient-monitoring accessory manufacturers, OEM and compatible alike.
What 510(k) clearance does NOT mean
- It is not "FDA approval." Class I and most Class II accessories are cleared, not approved. "FDA approved" is the wrong term for this device class and a sign of a vendor who is careless with regulatory language.
- It is not an endorsement of any OEM brand. A 510(k) for a "Philips-compatible" sensor does not mean Philips endorses it.
- Clearance is per device type, not per part number. One 510(k) typically covers a family of devices.
- It does not replace your own validation. Clearance is a regulatory floor, not a substitute for verifying performance on your specific monitor fleet.
- Go to the FDA 510(k) Premarket Notification database: accessdata.fda.gov 510(k) database
- Search by applicant / company name: Shenzhen Med-link Electronics Tech Co., Ltd.
- Cross-check the device type and product code against the accessory you are buying.
- Separately, the FDA Establishment Registration & Device Listing database confirms the manufacturing establishment is registered and the device is listed for U.S. commerce.
2. ISO 13485:2016 — the quality management system
What ISO 13485 certification is
ISO 13485:2016 is the international standard for a medical device quality management system (QMS). Certification means an accredited third-party body has audited the manufacturer's processes — design control, supplier control, production, traceability, complaint handling, corrective action — and confirmed they meet the standard. Without a certified QMS, a claim like "every unit goes through electrical continuity testing" is just words. With one, the testing is a documented, audited, repeatable process subject to external review.
MedLinket operates an ISO 13485:2016-certified QMS, certified by TÜV. MedLinket also holds ISO 9001, participates in MDSAP (the Medical Device Single Audit Program, recognised across multiple regulatory jurisdictions), and holds CE marking and MHRA registration for the EU and UK markets.
What ISO 13485 does NOT mean
- It certifies the system, not any individual product's performance.
- Certificates have an issue date and an expiry date; a current certificate matters, an expired one does not.
- "ISO 13485 certified" with no named certifying body and no certificate number is unverifiable.
- Request the ISO 13485:2016 certificate. A real certificate states the certificate number, the issuing body (TÜV, for MedLinket), the scope and the issue and expiry dates.
- Confirm the certificate is current and its scope covers your device type.
- Verify directly with the issuing body — TÜV operates an online certificate validation database where you enter the certificate number and confirm it is genuine and active.
3. $5 million product liability insurance — why it is the most practical trust signal
What product liability insurance covers
PLI covers claims arising from harm allegedly caused by a defective product. For a hospital, this is the part of supplier due diligence that risk management cares about most: if a compatible accessory is implicated in a patient-safety event, is there real financial backing behind it, or just a small company that disappears? MedLinket carries $5 million in product liability insurance — a meaningful figure for a patient-monitoring accessory manufacturer.
The detail that actually matters: Additional Insured
A PLI policy with a stated limit is good. A PLI policy under which your hospital can be named as an Additional Insured is what your risk department is really looking for. An Additional Insured endorsement extends certain protections of the supplier's policy to the named hospital. MedLinket can provide a Certificate of Insurance with an Additional Insured endorsement on request for hospital customers.
- Request a Certificate of Insurance. A genuine COI names the insurer, the policy number, the coverage type and limit, and the policy period.
- For hospital purchases, request the COI with your facility named as Additional Insured and confirm the endorsement language with your own risk / legal team.
- A COI can be confirmed with the issuing insurer or broker shown on the certificate.
4. Two more verifiable facts worth knowing
MedLinket is a publicly listed company
MedLinket (Shenzhen Med-link Electronics Tech Co., Ltd.) is listed on China's NEEQ market under stock code 833505. A public listing means audited financials and regulated disclosure — a level of transparency a private shell distributor cannot offer. You can confirm the listing through NEEQ's public records using the stock code.
MedLinket is a specialist manufacturer, not a trading company
MedLinket has operated since 2004 — over 20 years — exclusively in patient-monitoring accessories, manufacturing in a Class 100,000 cleanroom with 3,500+ tooling molds in service and serving 2,000+ hospitals across 117 countries. This distinguishes a manufacturer that controls its own design and QC from a reseller that simply rebrands whatever is cheapest.

5. The Magnuson-Moss Warranty Act — why compatible accessories do not void your monitor warranty
Under the U.S. Magnuson-Moss Warranty Act (15 U.S.C. § 2302(c)), a manufacturer generally cannot condition a warranty on the use of branded parts or accessories unless those parts are provided free of charge or the manufacturer obtains a waiver. In plain terms: an OEM cannot void your monitor warranty simply because you used a properly cleared compatible SpO2 sensor or ECG cable. This is covered in more depth in Magnuson-Moss Warranty Act and Compatible Medical Accessories.
A supplier-verification checklist you can use on any vendor
| What to verify | Good answer | Red flag |
|---|---|---|
| FDA status | Names the registered entity and product code; says "cleared," not "approved" | "FDA approved," no entity name, no product code |
| ISO 13485 | Current certificate with number, issuing body, scope, expiry | "ISO certified," no number, no body, expired |
| Product liability insurance | Provides a COI; offers Additional Insured endorsement for hospitals | No COI; vague "we're insured"; no policy number |
| Corporate transparency | Verifiable legal entity; public listing or auditable records | Untraceable trading company; no fixed entity |
| Performance data | Provides bench / clinical test data and the standard used | "Trust us, it works" with no data |
| Honesty about limits | States what it does NOT test or guarantee | Claims to test everything; no disclosed limitations |
What this page does not claim
- We do not claim FDA approval — patient-monitoring accessories of this class are FDA cleared or listed, and we use the correct term.
- We do not claim OEM endorsement. No statement on this page implies Philips, GE, Mindray, Dräger, Nihon Kohden, Masimo or Medtronic / Covidien endorses MedLinket.
- We do not claim that certification removes your obligation to validate accessories on your own equipment and within their cleared intended use.
- We do not publish live certificate numbers on a public page; we provide them to verified buyers and explain how to validate them with the issuing authority.
A supplier that admits what its certifications do not cover is more trustworthy than one that implies they cover everything.
Frequently asked questions
Is MedLinket "FDA approved"?
No — and no maker of this device class should say so. Class I and most Class II patient-monitoring accessories are FDA cleared (via 510(k)) or listed, not "approved." A number of MedLinket device types hold FDA 510(k) clearance, and the manufacturing establishment is FDA-registered with devices listed for U.S. commerce. You can confirm both yourself in the FDA 510(k) and Establishment Registration & Device Listing databases under "Shenzhen Med-link Electronics Tech Co., Ltd."
How do I verify the ISO 13485 certificate without relying on MedLinket?
Request the ISO 13485:2016 certificate — it states the certificate number, the issuing body (TÜV), the scope, and the issue/expiry dates. Then enter the certificate number directly into TÜV's online certificate validation database. Once you have the number, the validation step does not depend on MedLinket at all.
Can my hospital be named on the $5M product liability policy?
Yes. MedLinket can provide a Certificate of Insurance with an Additional Insured endorsement on request for hospital customers, naming your facility. A genuine COI names the insurer, policy number, coverage type and limit, and policy period, and can be confirmed with the issuing insurer or broker.
Does using a compatible accessory void my monitor's warranty?
Generally no. Under the U.S. Magnuson-Moss Warranty Act (15 U.S.C. § 2302(c)), an OEM cannot condition a warranty on the use of branded parts unless those parts are supplied free or a waiver is obtained. Using a properly cleared compatible SpO2 sensor or ECG cable does not, by itself, void a monitor warranty.
