No
The device description clearly states it is a "mechanical wheelchair" and a "manually operated device." There is no mention of AI, ML, or any computational components that would suggest the use of such technology. The performance studies focus on mechanical and biocompatibility standards.
No.
This device is a manual wheelchair, which provides mobility, but does not provide therapy or treatment for any disease or condition.
No
Explanation: The device, a manual wheelchair, is intended to provide mobility to persons restricted to a sitting position. It is a mechanical device for physical assistance and does not perform any diagnostic functions like detecting, monitoring, or diagnosing a medical condition.
No
The device description clearly states it is a "mechanical wheelchair" and details physical components like a frame, seat, footrests, and wheels, indicating it is a hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide mobility to persons limited to a sitting position. This is a physical function, not a diagnostic test performed on samples taken from the human body.
- Device Description: The description details a mechanical wheelchair with wheels, frame, seat, and footrests. This is a physical assistive device.
- Lack of IVD Characteristics: The description does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.) to diagnose, monitor, or screen for diseases or conditions.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens from the human body. This wheelchair operates in vivo (on the body) to provide physical support and mobility.

Device Description
The YJ- K1,K2 series are mechanical wheelchairs which are a manually operated devices with wheels that are intended for medical purposes to provide mobility to persons restricted to a sitting position. It can be folded for transport by bring the two sides together. The manual wheelchair incorporates a main frame, a seat, two adjustable footrests and four wheels. The larger rear wheels have hand rims of slightly smaller diameter projecting just beyond the tire. These allows the user to manoeuvre the chair by pushing them on without requiring them to grasp the tires. The manual wheelchairs have brakes that bear on the tires of the rear wheels and two push handles at the upper rear of the frame to allow for manual propulsion by an assistant.

Dear Eva Li:
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.

| Similar*1: | Compare the predicate device, the subject device add two skirt guards which installed to the sides of the seat frame under the arm rests to provide a barrier between the occupants and the wheels. This feature can prevent occupant s' clothes from getting caught in the wheels. And the subject device equipped Anti-tipper (selected models), brake extender(selected models). This feature will not raise any new risk of safety or effectiveness. |
|---|---|
| Different*2: | Compare the predicate device, the subject device have different value on the unfold size, stowage size, device weight, Capacity, Seat Width, Seat height, Seat depth, Tires size. However the subject has pass the and , so the above different will not raise any new risk of safety or effectiveness. |
| Different*3: | Compare the predicate device, the subject device armrest have various options. These difference will not raise any new risk of safety or effectiveness. |
| Similar*2 | The Safe Operational incline is not identical, the subject device pass the bench performance. So it will not raise any new risk of safety or effectiveness. |
7. Summary of Non-Clinic Performance Testing
