    Midmark 631 Procedure Chair

    The right procedure room equipment can make a crucial difference in both patient outcomes and caregiver safety. Particularly for patients with mobility limitations, accessible in-office procedure environments are essential. Unfortunately, many procedure chairs on the market today can create barriers to patient access. That's why we designed the Midmark 631 Procedure Chair.

    Accessibility

    • The Midmark 631 has a US Access Board compliant 17-inch low seat height (while maintaining a 39-inch high seat height.)
    • Transfer patients onto the 28 or 32-inch wide transfer surface with assistance from compliant Patient Support Rails.
    • The chair is compatible with patient lifts and helps ensure safe patient transfer with no interference.
    • Utilize US Access Board compliant Knee Crutches to support the patient's thigh, knee, and calf during lower body exams and procedures.

    Comfort

    • Position patients up to 650 pounds effortlessly and comfortably with 8-way powered positioning.
    • The Motion Profiling® feature allows patients to adjust comfortably while seated on the chair without the need to readjust.
    • Extend the footrest to accommodate the needs of taller patients.

    Safety

    • The 631 is designed with features that help ensure ample access to the patient while helping the caregiver maintain an ergonomic working position whether seated or standing.
    • Avoid impact or disruption while moving the chair. Active Sensing Technology® pauses chair movement when disrupting impact is detected.
    • Several accessories are available to help ensure safety and security while on the chair.

    The future of patient care starts now.
