Dear Charles Mack:

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.

### Device Description:

### Aneroid Sphygmomanometer

The Aneroid Sphygmomanometer is a non-invasive blood pressure measurement system for monitoring blood pressure levels. This Non-automated Sphygmomanometer uses an occluding cuff and an aneroid sphygmomanometer to measure pressure. The proposed device is OTC, non-invasive, non-automated, and non-sterile.

The proposed device consists of an aneroid qauge, cuff, bladder, and inflation bulb. There are four models, including AS-ND-001, AS-ND-001LG, AS-ND-001CH, and AS-D-001. The differences between models are in the size, color, and material of the cuff.

### Single Patient Use Aneroid Sphygmomanometer

The device is intended to be manually attached to a patient and manually inflated, along with a manual method for detecting Korotkoff sounds. The proposed device is OTC, non-invasive, non-automated, and non-sterile.

The proposed device consists of a manometer, cuff, and inflation bulb. There are four models: AS-SPU-W, AS-SPU-Y, AS-SPU-LG, and AS-SPU-CH. The differences between models are in the size and color of the cuff.

Both types of aneroid sphygmomanometers use the same measurement method of the Korotkoff sounds method; they are all reusable same measurement range and accuracy. The single-patient use type is for single-patient multiple uses only to avoid cross infection. Both types of aneroid sphygmomanometer can be sold with/without optioned stethoscopes which have been listed with the FDA.

The proposed device is Over-The-Counter use, non-sterile, reusable device.

### Principles of Operation/Measurement Method:

Auscultatory Korotkoff sounds method

### Discussion:

### Note 1: Indications for use

The subject devices, including the conventional type and single patient use type, are both reusable. The measurement method and intended use for both types are the same as our previously cleared predicate device and reference device, except the single-patients use type is for single-patient use only. Both conform to the same applicable performance standards.

The indication for use statement for the subject devices has been standardized to meet the requirements of most recently cleared devices under product code-DXQ and similar reference devices. The difference doesn't raise new questions of safety or effectiveness compared to the predicate.

### Note 2: Patient Population

The tarqet population of the subject devices is larger than the predicate device but still covered by the reference devices, the same as most recently cleared aneroid sphygmomanometer devices.

They conform to the same performance standards (ISO81060-1). Therefore, the difference in the target population does not raise new questions on the safety and effectiveness of the subject device.

### Note 3: Material

Although minor material differences exist among subject devices, predicate devices, and reference devices, they all conform to the same ISO10993-1 biocompatibility standards.

### Note 4: Cuff circumference

The arm circumference for the proposed cuff is 120 mm-508 mm, and the arm circumference for the predicate cuff is 240-320 mm, the arm circumference for the reference cuff is 100 mm - 620 mm. The range of arm circumferences for the subject device is covered by the reference device, and they conform to the same performance standards; therefore, the difference in cuff circumference does not raise new questions on the safety and effectiveness of the subject device.

{11}------------------------------------------------

# Note 5: Cuff sizes

The subject device's cuff sizes differ from the predicate and reference devices. However, the cuff size of the subject device is similar to the predicate device and the reference device. The Velcro on the cuff is designed to fit various arm circumferences. This difference doesn't raise new problems reqarding the safety and effectiveness of the subject device. Therefore, this difference in cuff size does not introduce new questions on the safety and efficacy of the subject device.

### Note 6: Cuff bladder size

The cuff bladder size is similar to the predicate device and reference device for Aneroid Sphygmomanometer. It could fit various requirements of users. For Sinqle Patient Use of an Aneroid Sphygmomanometer, the cuff bladder is integrated with the cuff and has no separate bladder.

However, the subject devices conform to ISO 81060-1. Therefore, this difference in cuff bladder size does not raise new questions on the safety and effectiveness of the subject device.

# Performance Testing

Performance testing was provided to support the substantial equivalence determination and to validate & verify that the subject devices met all requirements of related applicable standards. The results of these tests demonstrate compliance with the requirements of the consensus standards noted below.

### Non-Clinical Testing

Non-clinical testing was performed to verify substantial equivalence to the predicate device.

{12}------------------------------------------------

# K222652

# Performance:

Non-invasive sphygmomanometers performance testing per ISO 81060-1:2007; ISO 81060-1 First edition 2007-12-01 Non-invasive sphygmomanometers - Part 1: Requirements and test methods for non-automated measurement type

# Biocompatibility:

The biocompatibility evaluation for the patient contact reusable cuff was conducted in accordance with the FDA Guidance "Use of International Standard ISO-10993: Biological Evaluation of Medical Devices Part 1: Evaluation and testing with a risk management process, September 4, 2020, and International Standard ISO 10993-1 Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process, as recognized by FDA. The testing items included: ISO 10993-5: 2009 In Vitro Cytotoxicity ISO 10993-10: 2010 Skin Irritation

ISO 10993-10: 2010 Skin Sensitization

# Clinical Performance Data

No clinical data were required to demonstrate substantial equivalence.

# Conclusions:

The differences between the predicate and the subject device do not raise any new or different questions of safety or effectiveness. The Aneroid Sphygmomanometer and Single Patient Use Aneroid Sphygmomanometer is substantially equivalent to the Cardicare Company, Ltd., Aneroid Sphygmomanometer With Stethoscope Model HBPK-A cleared under K082542 and the Aneroid Sphygmomanometer, Aneroid Sphygmomanometer with stethoscope, manufactured by Shanghai Caremate Medical Device Co. Ltd, cleared under K211084 concerning the indications for use, target populations, treatment method, and technological characteristics.
