Technological Characteristics

Manual aneroid sphygmomanometer. Materials: Aluminum/stainless steel gauge; PVC or natural latex bladder; Nylon or cotton cuff. Dimensions: Various cuff sizes (e.g., 510mm x 140mm to 260mm x 75mm). Sensing: Auscultatory Korotkoff sounds method. Energy: Manual. Connectivity: None. Sterilization: Not applicable.

Indications for Use

Indicated for measurement of systolic and diastolic blood pressure in children (2-12 years), young adults (12-21 years), and adults (>21 years). Used by medical professionals or at home. Anatomical sites include upper arm and leg (for children).

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.

Predicate Devices

# Discussion

Comparing with the predicate device, ANEROID SPHYGMOMANOMETER Model BK2002 (K043286), modified ANEROID SPHYGMOMANOMETER Model BK2002, BK2001-3001, BK2015 and BK2015-3001 have same product name, classification and product code, product physical design and operation, same Aneroid gauge, packaging

materials, performance parameter ranges, physical properties, mechanical properties, biocompatibility. The differences between those two devices are as following.

- . The AAMI SP9 standard which predicate device complied with is invalid to FDA recognized standard, and current recognized standard is ISO 81060-1:2010. All verification and validation activities, such as comparison test between modified device and original one was performed and the results demonstrated that predetermined acceptance criteria were met the requirement of standards.
- The Nylon cuff, PVC bulb and PVC bladder have been used with another predicate device (K111141, Bokang Digital Blood Pressure Monitor, Model BK6001 which use same bulb and cuff bladder). All the materials which contacts with body skin are no changed as predicate device, and meet the FDA requirement of Biocompatibility.
- The extended sizes of the cuffs are provided optionally in order to accommodate target population besides adults, such as infants, children and young adults. Based on the performance testing in this submission, the slight difference between these blood pressure cuffs does not raise any safety or effectiveness issue. All performance specification was verified to comply with the ISO81060-1 standard. (Please see section 18 of this submission)

# Non-Clinical Testing

Non-clinical testing included biocompatibility and bench testing. The tests listed in the ISO10993 and ISO81060-1, were included. Results of testing were acceptable.

# Clinical Study

No clinical study is included in this submission.

#### CONCLUSION

ANEROID SPHYGMOMANOMETER. MODEL BK2002 have the same intended use and similar technological characteristics as the above predicate devices. Moreover, information contained in this submission supplied demonstrates that any differences in their characteristics do not raise any new questions of safety or effectiveness. Thus, ANEROID SPHYGMOMANOMETER, MODEL BK2002, BK2002-3001, MODEL BK2002a, BK2002a-3001, BK2015, BK2015-3001 MODEL are substantially equivalent to the predicate devices.
