Indications for Use
ThyssenKrupp Accessibility's Battery Operated Stair Lift is intended to mechanically transport one mobility impaired person in a fold-down seat, up and down curved stairs, indoors.
Device Story
Battery-operated stair lift for indoor transport of one mobility-impaired person on curved stairs. Device consists of a fold-down seat with integrated footrest mounted to a rail system anchored to stair treads. Operates via planetary motor with worm gear drive; powered by two 7AH 12V batteries. Features include joystick control, safety belt, anti-squeeze mechanism, and patented electronic leveling system. Unique "en route" swiveling capability allows navigation of narrow staircases. Operated by the user via joystick; intended for home use. Provides ergonomic seating with reduced knee flexion. Benefits include energy conservation for users and safe, comfortable mobility within the home.
Clinical Evidence
No clinical data. Substantial equivalence is based on bench testing, design specifications, and compliance with international stair lift standards (ASME 18.1, IEC 60601-1-2:2007) and third-party certifications (ETL Listing, Lift Institute Type Approval).
Technological Characteristics
Materials: 80mm bended round steel tube. Drive: Planetary motor with worm gear. Power: 2x 7AH 12V batteries; 24VDC/2A charger. Connectivity: RF for call/send. Safety: Multiple safety devices, anti-squeeze, safety belt. Leveling: Electronic, sensor-controlled. Swiveling: "En route" electronic. Standards: ASME 18.1, IEC 60601-1-2:2007.
Indications for Use
Indicated for one mobility-impaired person requiring mechanical transport up and down curved indoor stairs.
Regulatory Classification
Identification
Powered patient stairway chair lifts: A powered patient stairway chair lift is a motorized lift equipped with a seat and permanently mounted in one location that is intended for use in mitigating mobility impairment caused by injury or other disease by moving a person up and down a stairway. All other powered patient transport: A powered patient transport is a motorized device intended for use in mitigating mobility impairment caused by injury or other disease by moving a person from one location or level to another, such as up and down flights of stairs (e.g., attendant-operated portable stair-climbing chairs). This generic type of device does not include motorized three-wheeled vehicles or wheelchairs.
Special Controls
(i) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized edition of American Society of Mechanical Engineers (ASME) A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must demonstrate that the safety controls are adequate to prevent a free fall of the chair in the event of a device failure; (ii) Appropriate analysis and nonclinical testing must demonstrate the ability of the device, including armrests, to withstand the rated load with an appropriate factor of safety; (iii) Appropriate restraints must be provided to prevent the user from falling from the device (such as that outlined in the currently FDA-recognized edition of ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”); (iv) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized editions of AAMI/ANSI/IEC 60601-1-2, “Medical Electrical Equipment—Part 1-2: General Requirements for Safety—Collateral Standard: Electromagnetic Compatibility—Requirements and Tests,” and ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must validate electromagnetic compatibility and electrical safety; and (v) Appropriate analysis and nonclinical testing must demonstrate the resistance of the device upholstery to ignition.
