Technological Characteristics
Aneroid manometer (aluminum or ABS); cuff bladder/tubing/bulb (neoprene, silicone rubber, natural latex, or PVC); nylon cuff. Manual inflation/deflation. Pressure range 0-300 mmHg, 2 mmHg intervals. Accuracy +/- 3 mmHg. Non-sterile, reusable. Biocompatibility per ISO 10993-1, -5, -10. Performance per ISO 81060-1.
Indications for Use
Indicated for measurement of systolic and diastolic blood pressure in newborns, infants, children, young adults, and adults. Used by medical professionals or in home settings. No specific contraindications listed.
Regulatory Classification
Identification
A blood pressure cuff is a device that has an inflatable bladder in an inelastic sleeve (cuff) with a mechanism for inflating and deflating the bladder. The cuff is used in conjunction with another device to determine a subject's blood pressure.

Dear Mark Chu:
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 (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 located 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.
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
{1}------------------------------------------------
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 of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-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 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

{7}------------------------------------------------
#### Different 1- Indications for use
The indications for use of proposed device include the target population, while the predicate device doesn't include this information. But they have the same target population, therefore, the proposed device and predicate device have the same indications for use.
#### Different 2- Material
The material of out shell of manometer, material of tubing and inflation bulb of proposed device is different from the predicate device. But these material is not the patient-contact material, therefore the difference on material does not raise new questions on safety and effectiveness of the proposed device.
#### Different 3 - Cuff sizes
The cuff sizes of proposed device are different from predicate device. However, the cuff size of proposed device is similar to the predicate device and the Cuff Circumference of the two devices is the same. The Velcro on cuff is designed to fit varies arm circumference. This difference doesn't raise new problems on the safety and effectiveness of the proposed device. Therefore, this difference on cuff size does not raise new questions on safety and effectiveness of the proposed device.
#### Different 4 - Cuff circumference
The arm circumferences for the proposed cuff is 100mm-620mm, and the arm circumferences for the predicate cuff is 100mm-660mm. The range of arm circumferences for proposed device is covered by that of the predicate device, the difference on cuff circumference does not raise new questions on safety and effectiveness of the proposed device.
#### Different 5 - Cuff bladder size
The cuff bladder size of the proposed device is partly different from predicate device. However, the cuff bladder size of proposed device is similar to the predicate device. It could fit varies requirements of users. This difference doesn't raise new problems on the safety and effectiveness of the proposed device. Therefore, this difference on cuff bladder size does not raise new questions on safety and effectiveness of the proposed device.
#### Conclusion
Based on the comparison and analysis above, the proposed devices are as safe, as effective, and performs as well as the legally marketed predicate device K192500.
