Intended Use

The Convertible® I-1000 I-Series Positioning and Transfer Chair is an electric positioning chair with motorized positioning control that can be adjusted to various positions. The device is used to alter postural positions and to provide a means of transferring a patient horizontally from a height adjustable bed or trolley, to the chair and vice versa. The chair can then be transformed from a supine position into the sitting position without ever lifting the patient.

This device may be used on a wide range of patients, including adults and children up to 1000 pounds.

Device Description

The Convertible® Positioning and Transfer Chair construction is made of steel tubular components, on to which is fitted foam filled upholstery. The mechanism allows the Convertible® Positioning and Transfor Chair to transform from the horizontal supine position into a chair, which can then be tilted. This is accomplished through the hand-held controller, which in turn operates two DC linear actuators. The first DC actuator allows the Chair and patient profile to change from a sitting position to a horizontal or supine position suitable for transferring. The second DC linear actuator allows the I-1000 to be independently inclined to the rear (Tilt-in-Space). A hand-held push button controller is used to engage actuator motion and vary the I-1000's position. The electric system is composed of a 24-volt rechargeable battery, an external battery charger, and a control unit. Recharging of the battery is accomplished via the external battery charger.

The Convertible® Positioning & Transfer Chair is ideal for moving those patients who are unable to move themselves. The Convertible® Positioning and Transfer Chair have been specifically designed to provide a means of transferring a patient horizontally from a height adjustable bed or trolley, to the chair and vice versa. The patient will always be supported either on the bed and/or the chair and is never suspended. To achieve this, The Barton® Positioning and Transfer System (PTS®) must be used.

AI/ML Overview

The provided text is a 510(k) Summary for a medical device called the "Convertible® I-1000 Positioning and Transfer Chair." This summary focuses on demonstrating substantial equivalence to predicate devices and adherence to general safety standards, rather than defining specific performance acceptance criteria for a diagnostic or AI-based device.

Therefore, many of the requested elements for acceptance criteria and a study proving device performance (e.g., sample size for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone algorithm performance, types of ground truth) are not applicable or not present in this type of submission.

The document describes performance in terms of mechanical and electrical safety and materials biocompatibility.

Here's a breakdown of the available information based on your request:

(Passed, details not specified)
Intended Use / Patient CapacityCapable of supporting adults and children up to 1000 pounds.The device is described as being used on a wide range of patients, including adults and children up to 1000 pounds, indicating it meets this capacity. (Implied by description and intended use, not a specific test result).

2. Sample size used for the test set and the data provenance:

  • Sample Size: "Representative sample for the device" was used for load and repeatability testing. No specific number is provided.
  • Data Provenance: The tests appear to have been conducted by Barton Medical Corporation or its contracted lab (Intertek Testing Services NA, Inc.) as part of the submission process, likely in the US (where the submitter is based) or Japan (where the manufacturer is located). This is a prospective engineering/device testing approach, not a retrospective analysis of clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Not applicable. This device is a mechanical positioning and transfer chair, not a diagnostic device or AI system requiring expert-established ground truth for its functional performance. The "ground truth" for its performance is determined by adherence to engineering standards and safety tests.

4. Adjudication method for the test set:

  • Not applicable. See point 3. Testing involves objective measurements against engineering standards.

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:

  • No. This is not a diagnostic device or an AI-assisted system. No MRMC study was performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

  • Not applicable. This is a mechanical device, not an algorithm.

7. The type of ground truth used:

  • Engineering Standards and Objective Measurements: The "ground truth" for the device's performance is established by its compliance with specified international and national engineering safety and performance standards (e.g., IEC 60601-1, IEC 60601-1-2, ISO 10993-10, EN 12531-12, JIS T9201, JIS Z0237) and internal load/repeatability requirements. Biocompatibility was assessed via laboratory testing (skin irritation evaluation).

8. The sample size for the training set:

  • Not applicable. This is a hardware device, not a machine learning model, so there is no "training set."

9. How the ground truth for the training set was established:

  • Not applicable. See point 8.
