Name of the Procedure:

Replacement of Power Wheelchair Accessory: Solid (Rubber/Plastic) Caster Tire with Integrated Wheel (E2392)

Summary

This procedure involves replacing a damaged or worn-out solid caster tire and its integrated wheel on a power wheelchair, ensuring continued safe and smooth operation.

Purpose

To maintain the functionality and safety of power wheelchairs by replacing compromised caster tires. The goal is to ensure mobility, prevent accidents, and enhance the user’s quality of life by providing stability and reliable movement.

Indications

• Significant wear and tear or damage to the existing caster tire.
• Reduced maneuverability and stability of the power wheelchair.
• Audible noise or visible wobbling during wheel movement.

Preparation

• Inspect the wheelchair to confirm the necessity of tire replacement.
• Ensure the new caster tire and wheel (size and type) match the wheelchair specifications.
• Gather all required tools, such as wrenches, screwdrivers, and a jack for lifting the wheelchair.

Procedure Description

1. Preparation:
   • Position the wheelchair on a stable, flat surface.
   • Use the jack to slightly lift the wheelchair to relieve pressure on the caster tire.
2. Removal:
   • Unscrew and remove the bolts/nuts holding the old caster tire and wheel.
   • Carefully remove the damaged caster tire and wheel from the fork.
3. Replacement:
   • Align the new caster tire and wheel with the fork.
   • Secure the new component by fastening screws and bolts.
4. Final Adjustments:
   • Lower the wheelchair and ensure it sits evenly on all wheels.
   • Conduct a test roll to verify proper installation and smooth operation.

No anesthesia or sedation is involved in this procedure.

Duration

Typically takes 30 minutes to 1 hour, depending on the availability of tools and the condition of the wheelchair.

Setting

Usually performed in an outpatient clinic or at home by a qualified technician or caregiver.

Personnel

Qualified technician or caregiver familiar with wheelchair maintenance and repairs.

Risks and Complications

• Improper installation leading to wheelchair instability.
• Use of incorrect tire size or type causing functional issues.
• Potential minor injuries from handling tools.

Benefits

• Restored wheelchair mobility and functionality.
• Enhanced safety and stability for the user.
• Improved quality of life with reliable wheelchair operation.

Recovery

• Immediate usability post-installation.
• No significant recovery time required.
• Periodic checks to ensure the tire remains in good condition.

Alternatives

• Use of air-filled (pneumatic) or foam-filled tires as replacements.
  • Pros: Better shock absorption (pneumatic), prevention of flats (foam-filled).
  • Cons: Pneumatic tires require regular maintenance; foam-filled tires can be heavier and more expensive.
• Consideration of a new wheelchair if multiple components are worn out.

Patient Experience

• Minimal discomfort during replacement.
• Immediate improvement in wheelchair maneuverability.
• Enhanced comfort due to restored smooth operation.
