Indications for Use
RH non-Automated Blood Pressure Meter is intended to be used by medical professionals or in the home for the measurement of systolic and diastolic pressure on children or adults. The device is intended to a patient and manually inflated along with a manual method for detecting Korotkoff sounds. There are a variety of stethoscopes can be an optioned accessory, depending on the model.
Device Story
Manual non-invasive aneroid sphygmomanometer; consists of inflation cuff, manual inflation bulb, and aneroid gauge. Models Max0201, Max0202, Max0203 include optional stethoscopes (single head, dual head, or Sprague Rappaport). Used by medical professionals or patients at home/clinical settings. Operator wraps cuff around upper arm (or leg for children), manually inflates/deflates via bulb and valve, and uses stethoscope to listen for Korotkoff sounds to determine systolic/diastolic pressure. Output is visual reading on aneroid gauge. Assists healthcare providers in monitoring patient blood pressure; aids in hypertension management and cardiovascular assessment.
Clinical Evidence
No clinical data. Bench testing only, including biocompatibility (ISO 10993-1, -5, -10) and performance testing (ISO 81060-1).
Technological Characteristics
Aneroid sphygmomanometer. Materials: aluminum/stainless steel (manometer), PVC/natural latex (tubing, bulb, bladder), nylon/cotton (cuff). Manual inflation/deflation. Measurement range 0-300 mmHg, 2 mmHg intervals. Accuracy +/- 3 mmHg. Complies with ISO 81060-1. No software or electronic components.
Indications for Use
Indicated for measurement of systolic and diastolic blood pressure in children and adults. Used by medical professionals or at home. Manual inflation and auscultatory detection of Korotkoff sounds.
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.

## Discussion
Comparing with the predicate device, ANEROID SPHYGMOMANOMETER (K173246), RH non-Automated Blood Pressure Meter, MODEL Max02 and RH non-Automated Blood Pressure Meter with Stethoscope, MODEL Max0201, Max0202, Max0203 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, the subject cuffs are the same like our own cleared under predicate K173426 and that the biocompatibility standards compliance/reports are the same. The differences between those two devices are as following,

Image /page/9/Picture/1 description: The image contains the logo for Wenzhou Renhua Instruments Co., LTD. The logo features a stylized, cursive "RH" in a light blue gradient. To the right of the logo, the company name is written in blue, with "WENZHOU RENHUA INSTRUMENTS CO.,LTD" on a single line.
- Comparing the predicate device ANEROID SPHYGMOMANOMETER (K173246), the design of new device is same as BK2002/BK2002a except there are no Gray, Red, Green and yellow cuff color included.
- Design of Stethoscope for new device, there are added the combination of "Dual head" Stethoscope (Max0202) and "Sprague Rappaport" Stethoscope (Max0203). The different type of Stethoscopes didn't raise any safety or effectiveness issue.
- All performance specification of new devices for various cuff sizes were 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
RH non-Automated Blood Pressure Meter, MODEL Max02 and RH non-Automated Blood Pressure Meter with Stethoscope, MODEL Max0201, Max0202, Max0203 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, RH non-Automated Blood Pressure Meter, MODEL Max02 and RH non-Automated Blood Pressure Meter with Stethoscope, MODEL Max0201, Max0202, Max0203 are substantially equivalent to the predicate devices.
