The provided text is a 510(k) premarket notification approval letter for the Bruno Electra-Ride™ Models SRE-1540 and SRE-1550, which are powered patient transport devices (stairlifts). This document focuses on regulatory approval rather than a detailed study evaluating specific acceptance criteria for device performance. Therefore, it does not contain the information required to answer your request regarding acceptance criteria and a study proving those criteria were met.
Specifically, the document does not include:
- A table of acceptance criteria and reported device performance.
- Sample size, data provenance, number or qualifications of experts, or adjudication methods for a test set.
- Information on multi-reader multi-case (MRMC) comparative effectiveness studies or standalone algorithm performance.
- The type of ground truth used.
- Sample size for the training set or how ground truth for the training set was established.
This document confirms that the device is "substantially equivalent" to legally marketed predicate devices, meaning it has similar indications for use and safety/effectiveness profiles to existing products on the market, but it does not detail the specific performance metrics or studies used to demonstrate this equivalence.
§ 890.5150 Powered patient transport.
(a)
Powered patient stairway chair lifts —(1)Identification. 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.(2)
Classification. Class II. The stairway chair 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 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.
(b)
All other powered patient transport —(1)Identification. 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.(2)
Classification. Class II.
