Product Structure: Positioning wheels, steering wheels, chair frame

Front wheels: 7" PU foam wheels

Rear wheels: 24" PU non-inflatable solid wheels

Application: For use during MRI examinations (no movement or transfer in a strong magnetic field, no suction, no impact on MRI examinations).

Note: 1. Wheelchair users are strictly prohibited from being transported in any form of transport vehicle while in their wheelchair. 2. Do not sit on a wheelchair and tilt it backwards in a vehicle without an anti-tilt device.

3. When using a wheelchair, do not tilt it to one side or lift it.

4. Do not use the brakes while the vehicle is in motion.

5. Do not stand on the pedals, as this may cause the wheelchair to tip over.

An MRI wheelchair is a specialized chair made from non-magnetic materials to safely transport patients into an MRI suite, which has a powerful magnetic field. Unlike standard wheelchairs, MRI wheelchairs are constructed with non-ferrous components and often have prominent "MR" markings to prevent them from being confused with regular chairs.  

Key features and purpose

Non-magnetic materials: Built with non-ferrous metals and special polymers so they are not pulled into the MRI machine's magnetic field. 

Safety: Essential for patient and equipment safety, as standard wheelchairs can contain ferromagnetic materials that pose a serious hazard in an MRI environment. 

Identification: Clearly marked with "MR" labels or other distinctive colors to prevent accidental use in a non-MRI area and to distinguish them from magnetic wheelchairs. 

Variety of sizes: Available in a range of sizes and weight capacities to accommodate different patient needs. 

MR Conditional: The term "MR Conditional" indicates that the wheelchair is safe to use in an MRI environment under specific conditions, such as within a certain magnetic field strength (e.g., 3 Tesla or 7 Tesla). 

To use an MRI wheelchair, follow standard wheelchair operation while adhering to specific safety protocols for the MRI environment, such as ensuring the wheelchair is MR-safe and performing patient transfers outside of the strong magnetic field. MRI wheelchairs are made of non-magnetic materials like aluminum or titanium and are clearly marked to distinguish them from standard, magnetic wheelchairs. Use the hand rims to propel forward and backward, or to turn by pushing one wheel more than the other. Always secure the brakes and ensure footplates are clear when transferring. 

Before using the wheelchair

Check for MR safety: Ensure the wheelchair is labeled as "MR Safe" or "MR Conditional" and is made of non-ferrous, non-magnetic materials like aluminum or titanium. 

Perform pre-screening: Use Ferromagnetic Detection Systems at the entrance to the MRI area to ensure no ferromagnetic objects are entering the room. 

Follow safety protocols: Place the wheelchair in a designated, labeled area within Zone III (the controlled area before Zone IV, the scanner room). 

How to operate the wheelchair

To move forward: Place your hands on the metal rims on the outside of each wheel and push down on them simultaneously. 

To move backward: Pull the rims backward. 

To turn: To turn, push more vigorously with the hand on the side you want to turn toward, or hold one rim still while pushing the other forward. 

Patient transfer and safety

Position the wheelchair: Place the wheelchair near the boundary of Zone III and IV to allow for smooth patient transfers without bringing unnecessary items into the scanner room. 

Use the brakes: Always engage the brakes and ensure footplates are out of the way before and during any transfer to or from the chair.
