No
The description focuses on standard powered wheelchair components and control mechanisms (joystick, motor, battery) and explicitly states "Mentions AI, DNN, or ML: Not Found".
No.
The device is a powered wheelchair intended to provide mobility, which is a supportive function, not a therapeutic treatment for a medical condition.
No
The device is a powered wheelchair intended to provide mobility, not to diagnose a condition.
No
The device description explicitly lists numerous hardware components including batteries, motors, wheels, frame, and a control panel, indicating it is a physical device with integrated software for control.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide mobility to disabled or elderly individuals. This is a functional aid, not a diagnostic tool.
- Device Description: The description details the components of a powered wheelchair, all of which are related to physical movement and control. There are no components mentioned that would be used to examine specimens from the human body.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in the body
- Providing information for diagnosis, monitoring, or screening of diseases or conditions.
- Performance Studies: The performance studies focus on physical characteristics, safety standards, and compliance with wheelchair-specific ISO standards. They do not involve any diagnostic performance metrics like sensitivity, specificity, or AUC.
This device is clearly a medical device intended for mobility assistance, not an in vitro diagnostic device.

Device Description
The subject device, Powered Wheelchair, mainly powered by battery, motivated by DC motor, driven by user controlling joystick and adjusting speed.
The Powered Wheelchairs consist of two foldable armrests, a backrest, a seat cushion, a safety belt, a foldable frame, two rear driving wheels with hub motor/electromagnetic brake assemblies, two pivoting casters, two Li-ion batteries, an off-board battery charger, a control panel, and an electric motor controller.
The XFGW30-107 and XFGW25-203 Powered Wheelchair is intended to provide mobility to a disabled or elderly person limited to a seated position.
Folding design: This foldable electric wheelchair has main frame, rear frame, backrest frame, seat frame, front wheel frame and battery frame. Release the locking device of the backrest frame and the rear frame, push the backrest frame downward, drive the seat frame to rotate toward the backrest frame with the rotating mechanism, the two armrest frames rotate towards the direction of the seat frame. At the same time two front wheel frames move to the direction of the seat frame. When the back cushion is in contact with the seat cushion, the folding is completed.
Joystick: This controls the speed and direction of the wheelchairs. Push the joystick in the direction you wish to go. The further you push it, the faster the speed. Releasing the joystick stops the wheelchair and automatically applies the brakes.
Controller: The controller includes a power switch, speed adjustment/driving module Indicator, speed/driving module decreasing button, speed/driving module increasing button, a horn button and a direction joystick. The operation interface controller receives the operation signal and transmits it to the main board of the controller body, and sends a control signal to the electric wheelchair to adjust and operate the electric wheelchair.
Wheel and frame connection method: First, the left and right frames are connected to the motor respectively, and then the motor shaft is connected to the wheel. The motor rotates to drive the wheels to rotate to drive the wheelchair.
Frame design: 1. The frame of this product is aluminum tube. 2. The operation mode of the folding mechanism is to remove the locking device by someone else and manually push the backrest frame to complete the folding operation under non-riding state.

Summary of substantial equivalence discussion:
The Powered Wheelchair model XFGW30-107 and XFGW25-203 complied with the
11
requirements of ISO 7176-1:2014, ISO 7176-2:2017, ISO 7176-3:2012, ISO 7176-4:2008, ISO 7176-5:2008, ISO 7176-6:2001, ISO 7176-7:1998, ISO 7176-8:2014, ISO 7176-9:2009, ISO 7176-10:2008, ISO 7176-11:2008, ISO 7176-13:1989, ISO 7176-14:2008, ISO 7176-15:1996, ISO 7176-16:2012, ISO 7176-21:2009, ISO 7176-22:2014, IEC 60601-1-2: 2014, IEC 62133-2:2017, ISO 10993-1:2018, ISO10993-5:2009, ISO 10993-10:2010.
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. Maximum obstacle climbing 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 biocompatibility of the Predicate device and Subject device meet the requirements of the ISO 10993-5:2009 & ISO 10993-10:2010. The flame retardant test of the seat cushion/back cushion and armrest of both subject device and predicate device is carried out according to the ISO 7176-16 test. Therefore, both devices are assured to be under the same safety level.
