Intended Use

Air Pressure Therapy System (Model:VU-IPCAM) is intended for home to temporarily relieve minor muscle aches and or pains, and to temporarily increase circulation to the treated areas in people who are in good health.

Device Story

Air Pressure Therapy System (Model: VU-IPC4M) is a home-use powered inflatable tube massager. It consists of an air pump, air pressure sensor, microprocessor, and inflatable sleeves (leg, arm, hip, or pant styles). The device operates by sequentially inflating and deflating air chambers within the sleeves to simulate kneading and stroking of tissues, moving from the limb end toward the body center. The user controls the device via a hand controller or mobile app (Bluetooth). The microprocessor manages inflation cycles, pressure levels, and timing based on selected modes. By providing graduated compression, the device aims to relieve minor muscle aches and pains and improve local circulation. The system includes safety features to prevent over-pressurization and ensures biocompatibility of sleeve materials.

Clinical Evidence

No clinical data. Bench testing only, including electrical safety (IEC 60601-1, IEC 60601-1-11), EMC (IEC 60601-1-2), battery safety (IEC 62133-2), biocompatibility (ISO 10993-5, ISO 10993-10), wireless coexistence (ANSI C63.27), pressure/time accuracy, seam strength, and software failure mode verification.

Technological Characteristics

Powered inflatable tube massager; 4-chamber design; molded ABS enclosure; 11.1V/1600mAh Li-ion battery; sleeves made of nylon cloth and polyether amine; microprocessor-controlled pneumatic system; Bluetooth connectivity; sterilization not specified; software-controlled inflation sequences.

Indications for Use

Indicated for healthy individuals for temporary relief of minor muscle aches/pains and temporary increase in circulation to treated areas (leg, arm, hip, back).

Regulatory Classification

Identification

A powered inflatable tube massager is a powered device intended for medical purposes, such as to relieve minor muscle aches and pains and to increase circulation. It simulates kneading and stroking of tissues with the hands by use of an inflatable pressure cuff.

Dear Libray Chang:

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.

{1}------------------------------------------------

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).

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 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-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 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.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
