Dear Wang Ray:
We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule").

Indication for use Statement:
SpO2 Extension Cables are intended to be used to connect SpO2 sensors, placed at appropriate sites on the patient to a monitoring device for SpO2 monitoring by health care professional.
Device Description:
SpO2 Extension Cable consists of two parts: the SpO2 patient cable and the adapter. The SpO2 patient cable is used for connecting the monitors, and the adapter is used for connecting the SpO2 patient cable and the SpO2 sensor.
The SpO2 Extension Cable is the replacements for similar cables manufactured by Original Equipment Manufacturers (OEM) and other third party after market manufacturers for their respective monitors.
By using the same types of construction and technological characteristics to the compatible patient monitor and SpO2 sensor, the SpO2 Extension Cable can avoid measured data corrupted.
The proposed device was modification from the legally marketed (existing) device "SpO2 Extension Cable"/K222370, manufactured by "Beijing Rongrui-Century Science & Technology Co., Ltd.", same as the sponsor of this submission.
Compared to the initial product (K222370), only the structure of the SpO2 Extension Cable has changed. Originally a non-separable complete extension cable, now an extension cable can be separated into two parts, called the SpO2 patient cable and the adapter.
The type of instrument connector (which connects one end of the monitoring device) for the SpO2 patient cable is 20pin, there are four types pairing interfaces between SpO2 patient cable and adapter, the pairing interfaces name for the SpO2 patient cable and adapter connection is DB9F-LNCS, MLNCS-MLNCS, LNOP-LNOP, RD-RD and the other end of the adapter connecting to SpO2 sensor is DB9F. Adapters are divided into two categories: with cable and without cable. Adapters for each type of interface are available with and without cables.
