Quickie manual wheelchairs empower physically chailenged persons by Quickle manual whicelonano chaptires includes temporary and permanent conditions in all ages such as : Arthritis Amputee Paraplegic Cerebral Palsy Hemiplegic Tetraplegic Quadriplegic Spina Bifida Head Injury or Trauma Muscular Dystrophy Multiple Sclerosis Polio Geriatric condition and other Immobil- ing or debilitating condition
Claim being added: A wheelchair with the Bus Transport option, may be used for motor vehicle transportation, with the use of Wheelchair tiedown and occupant restraint systems (WTORS) that meet the requirements of SAE J2249.
For people with disabilities who are unable to transfer from their wheelchairs when traveling in motor vehicles, the wheelchair must serve as the vehicle seat. Therefore, the wheelchair must be secured to the vehicle so that it does not impose forces on its occupant and/or become a hazard to other vehicle occupants in a collision or sudden vehicle maneuver. Providing occupant protection for the wheelchair-seated occupant, therefore, requires that equipment be installed to secure the wheelchair and restrain the user. The bus transport models of the Zippie, Quickie, and Breezy Series manual wheelchairs are chairs that can be used in motor vehicle transport. The key change covered by this submission is the addition of securement hardware to the wheelchairs so that they can be used in motor vehicle transport. Each bus transport model includes securement hardware that is bolted to the wheelchair or installed at the factory. The securement hardware is identified by proper labeling. The labeling identifies the locations to which the wheelchair tiedown and occupant restraint systems or WTORS secure to the vehicle. WTORS are complete restraint systems for wheelchair-seated occupants. They are comprised of a system or device for wheelchair tiedown as well as a separate system for restraining the occupant. WTORS include all anchorage hardware and anchorage fasteners (or specifications for anchorage fasteners) required for installing and using the system in a vehicle. These WTORS secure the wheelchair and the occupant to the vehicle; they do not secure the occupant to the chair. WTORS will not be supplied by Sunrise Medical.
The provided text describes specific details about a wheelchair product rather than an AI/ML powered device. As such, information regarding AI/ML-specific criteria like multi-reader multi-case studies, standalone performance, training set details, or expert consensus for ground truth establishment is not present. Therefore, I can only extract information relevant to the device described.
Here's an analysis of the provided text:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Performance Requirements) | Reported Device Performance |
|---|---|
| Meet SAE J2249 Recommended Practice (Issued October 1996), "Wheelchair Tiedown and Occupant Restraint Systems for Use in Motor Vehicles" for design, test methods, and performance regarding dynamic performance in a 48-km/h, 20-g frontal impact. | The wheelchairs made by Sunrise Medical "have been thoroughly tested and have been shown to sustain the forces of a frontal impact crash test acceptably." |
| Structural integrity of the chair during a crash. | The wheelchairs "have been throughly tested and have been shown to sustain the forces of a frontal impact crash test acceptably." |
| Wheelchair travel determined by chair securement points. | The chairs include securement hardware that is bolted to the wheelchair or installed at the factory; labeling identifies securement locations. |
| Wheelchair travel determined by the performance of the WTOR. | This is explicitly stated not to be the product of Sunrise Medical; the WTORS are separate systems. |
| Proper product labeling for bus transport models. | Bus transport models include securement hardware identified by proper labeling. Labeling identifies locations for WTORS securement. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The text does not specify a distinct "test set" sample size in terms of the number of wheelchairs tested or the number of crash tests performed. It states "The wheelchairs made by Sunrise Medical have been throughly tested," but provides no quantitative details on the number of units or tests. The data provenance is not mentioned.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
No information is provided regarding experts or ground truth establishment in this context. The acceptance criteria are based on the SAE J2249 standard, which dictates test methods and performance requirements.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
No adjudication method is mentioned. The testing performance is evaluated against the SAE J2249 standard.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable as the submission is for a physical medical device (wheelchairs) and not an AI/ML-powered device or a diagnostic tool involving human readers.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
This is not applicable as the submission is for a physical medical device (wheelchairs) and not an AI/ML algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for the device's performance is compliance with the SAE J2249 Recommended Practice for "Wheelchair Tiedown and Occupant Restraint Systems for Use in Motor Vehicles," specifically its requirements for dynamic performance in a frontal impact crash test. This standard-based performance is the benchmark.
8. The sample size for the training set
This is not applicable as the submission is for a physical medical device and not an AI/ML model that requires a "training set."
9. How the ground truth for the training set was established
This is not applicable as the submission is for a physical medical device and not an AI/ML model.

510(k) SUMMARY OF SAFETY AND EFFICACY 13.0
Submitter: Rebecca Andersen September 16, 1997 Date:
Name(s) of the device(s):
Multiple
Identification of predicate device(s):
Sunrise Medical's Zippie, Quickie, and Breezy Series Wheelchairs
Description of the device:
For people with disabilities who are unable to transfer from their wheelchairs when traveling in motor vehicles, the wheelchair must serve as the vehicle seat. Therefore, the wheelchair must be secured to the vehicle so that it does not impose forces on its occupant and/or become a hazard to other vehicle occupants in a collision or sudden vehicle maneuver. Providing occupant protection for the wheelchair-seated occupant, therefore, requires that equipment be installed to secure the wheelchair and restrain the user.
The bus transport models of the Zippie, Quickie, and Breezy Series manual wheelchairs are chairs that can be used in motor vehicle transport. The key change covered by this submission is the addition of securement hardware to the wheelchairs so that they can be used in motor vehicle transport. Each bus transport model includes securement hardware that is bolted to the wheelchair or installed at the factory. The securement hardware is identified by proper labeling. The labeling identifies the locations to which the wheelchair tiedown and occupant restraint systems or WTORS secure to the vehicle.
WTORS are complete restraint systems for wheelchair-seated occupants. They are comprised of a system or device for wheelchair tiedown as well as a separate system for restraining the occupant. WTORS include all anchorage hardware and anchorage fasteners (or specifications for anchorage fasteners) required for installing and using the system in a vehicle. These WTORS secure the wheelchair and the occupant to the vehicle; they do not secure the occupant to the chair. WTORS will not be supplied by Sunrise Medical.
{1}------------------------------------------------
The SAE J2249 Recommended Practice (Issued October 1996), "Wheelchair Tiedown and Occupant Restraint Systems for Use in Motor Vehicles", applies to WTORS comprised of a system or device for wheelchair tiedown and a system or device for restraining the wheelchair-seated occupant. It specifies design requirements, test methods, and performance requirements for WTORS, requirements for manufacturer's instructions to installers and users, and requirements for product marking and labeling. SAE J2249 places particular emphasis on the design requirements, test procedures, and performance requirements for the dynamic performance of WTORS in a 48-km/h, 20-g frontal impact.
Sunrise chairs are configured to customer orders when sold. Configuration to order allows flexibility. Features such as width, depth, and back height are specified and may range from 14 to 22 inches. Specific configuration includes chair accessories and desired safety features. Any combination of features from the approved matrix may be configured to create the chair features needed by a given rider It is the rider and the health care professional that determine the appropriate configuration for the users needs. As the individuals condition or size change, other components or accessories may be ordered and the chair reconfigured to meet the evolving needs of its user.
Warnings, cautions and contraindications that apply to the use of WTORS are detailed in the users manual supplement, included in Appendix A
COMPARISON OF DEVICE CHARACTERISTICS TO PREDICATE(S):
This device has the same technological and performance characteristics as the predicated devices. There are no new issues of safety or efficacy introduced by the bus transport models of the Zippie Quickie, or Breezy Series wheelchairs, other than the safe and effective performance of the wheelchair securement hardware. The safety of the occupant is controlled by the independent occupant restraint system. The chair related issues of safety for the occupant during a crash are related to the structural integrity and travel of the chair. The travel of the chair is determined by 1) the chair securement points, and 2) the performance of the WTOR (not our product). The wheelchairs made by Sunrise Medical have been throughly tested and have been shown to sustain the forces of a frontal impact crash test acceptably. The wheelchairs can be used in bus transport if they have the securement hardware, proper product labeling and are properly secured to the vehicle.
