The Multilift Vertical Platform Lift is intended to mechanically transport an individual in a wheelchair directly between floors in a private residence.
The Multilift is similar to other products in commercial distribution. These products, like the Multilift, utilize electrically driven, wall-mounted on self-standing platform units to enable individuals in wheelchairs to travel up and down between floors in a residential or public setting.
I am sorry, but based on the provided text, there is no information about acceptance criteria, device performance, a study, sample sizes, data provenance, expert qualifications, adjudication methods, multi-reader multi-case studies, standalone performance, or ground truth.
The document is a 510(k) summary for a vertical platform lift (Multilift) and focuses on establishing substantial equivalence to a predicate device (Savaria V-1504 Vertical Platform Lift). It primarily discusses the device's description, intended use, and comparison to the predicate, as well as the FDA's regulatory decision. It does not contain details of a performance study or testing that would typically address the criteria you've outlined.
§ 890.3930 Wheelchair elevator.
(a)
Permanently mounted wheelchair platform lift —(1)Identification. A permanently mounted wheelchair platform lift is a motorized vertical or inclined platform lift device permanently installed in one location that is intended for use in mitigating mobility impairment caused by injury or other disease by providing a guided platform to move a person from one level to another, with or without a wheelchair.(2)
Classification. Class II. The permanently mounted wheelchair platform lift is exempt from premarket notification procedures in subpart E of part 807 of this chapter, subject to § 890.9 and the following conditions for exemption:(i) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized edition of 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 platform in the event of a device failure;
(ii) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized edition of ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must demonstrate the ability of the device to withstand the rated load with an appropriate factor of safety;
(iii) Appropriate analysis and nonclinical testing (such as that outlined in the currently FDA-recognized edition of ASME A18.1 “Safety Standard for Platform Lifts and Stairway Chair Lifts”) must demonstrate the ability of the enclosures to prevent the user from falling from the device; and
(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.
(b)
Portable wheelchair elevators —(1)Identification. A portable wheelchair elevator is a motorized lift device that is not permanently mounted in one location and that is intended for use in mitigating mobility impairment caused by injury or other disease by providing a means to move a person, with or without a wheelchair, from one level to another (e.g., portable platform lifts, attendant-operated stair climbing devices for wheelchairs).(2)
Classification. Class II.
