Intended Use
The Power Wheelchair, W5521, is a motor driven, indoor transportation vehicle with the intended use to provide mobility to a disabled or elderly person limited to a seated position.
Device Description
This Power wheelchair, W5521, is a motor driven, indoor transportation vehicle, which a device for assisting action handicapped people and disabled people to move. It is suitable for disabled people with mobility difficulties and elderly people. The device consists of front wheel, drive wheel, frame, controller, motor and drive devices, armrest, push-handle, backrest, seat cushion, footrest, battery box and charger. The device is powered by a Li-ion Battery pack (24V 10Ah, 240Wh) with 10 Km (6.2 miles) range, which can be recharged by an off-board battery charger that can be plugged into an AC socket outlet (100-240V, 50/60Hz) when the device is not in use. The user can activate the controller handle (joystick) to control the speed and direction of the wheelchair movement. In addition, when the patient releases the joystick will return back to the central position and the wheelchair will be automatically stopped soon due to automatic electromagnetic brake system. Once the joystick is activated again move to other position, the wheelchair will be re-energized.
More Information

No
The description focuses on basic electromechanical control via a joystick and an automatic braking system, with no mention of AI or ML terms or functionalities.

No
The device is described as an indoor transportation vehicle to provide mobility, not to treat, diagnose, or cure a disease or condition.

No

The device is described as a motor-driven transportation vehicle used for mobility, not for evaluating or diagnosing medical conditions.

No

The device description explicitly lists numerous hardware components including wheels, frame, controller, motor, battery, and charger, indicating it is a physical device with integrated software, not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to provide mobility to a disabled or elderly person. This is a physical assistance device, not a device used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
  • Device Description: The description details a mechanical and electrical device for transportation, not a device for analyzing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological specimen. There are no reagents, assays, or laboratory procedures described.

The device is clearly a power wheelchair intended for personal mobility.

The intended uses for both devices are the same. Mainframes of two devices are folded by way of front and rear close, and frame materials all meet the Tensile Strength, Yield Load, and Elongation tests. The design principles of the controller and Driving system are the same, and both meet the requirements of the ISO 7176-14:2008. Software validation is carried out on both control systems. Brake system and speed control are designed in the same way as well, and both meet the requirements of the ISO 7176-3:2012. Turning radius and Maximum safe operational incline are slightly different while such differences will not impact the safety and effectiveness of the subject device or raise new safety and effectiveness concerns as well as both meet the requirements of the ISO 7176-2:2001, ISO 7176-10:2008.

The flame retardant test of the seat cushion/backrest of the subject device is conducted according to ISO 16840-10, while the predicate device is carried out according to the ISO 7176-16 test. Both of the two testing methods are recognized consensus standards for flammability resistance. Therefore, both devices are assured to be under the same safety level.

In conclusion, the technological characteristics, features, specifications, materials, mode of operation, and intended use of the device substantially equivalent to the predicate devices quoted above. The differences between the subject device and predicate devices do not raise new issues of safety or effectiveness. The differences between the subject device and predicate devices do not raise new issues of safety or effectiveness.
