Indications for Use
The Intended Use of the Pride Mobility T3 Lift Chair is to provide lift assistance for persons who have difficulty rising from a seated position to a standing position.
Device Story
T3 Lift Chair is an upholstered electric positioning chair with a welded steel frame. It utilizes a dual-actuator system powered by a low-voltage DC motor (24/39V DC) converted from standard household AC (110V/240V). The user operates the chair via a hand control switch to transition between reclining, sitting, and standing positions. The dual-actuator design allows independent movement of chair components for improved comfort. The device is intended for use in home or clinical settings to assist individuals with mobility limitations in standing up. It includes an external transformer and battery backup for safety. The chair benefits patients by providing mechanical lift assistance, reducing the physical effort required to transition from a seated to a standing position.
Clinical Evidence
No clinical data. Bench testing only, including flammability (CAL 117, BS5852), electromagnetic emissions/immunity (EN 61000-6-3, EN 61000-6-1), electrical safety (EN60601-1), and mechanical fatigue/cycle/impact/downward force testing.
Technological Characteristics
Welded steel frame; foam and fabric upholstery compliant with CAL 117 and BS5852; dual-actuator DC motor system (24/39V DC); external transformer with battery backup; hand control switch; electrical safety per EN60601-1; electromagnetic compatibility per EN 61000-6-3/6-1.
Indications for Use
Indicated for persons having difficulty rising from a seated position to a standing position.
Regulatory Classification
Identification
An electric positioning chair is a device with a motorized positioning control that is intended for medical purposes and that can be adjusted to various positions. The device is used to provide stability for patients with athetosis (involuntary spasms) and to alter postural positions.
Special Controls
(1) Appropriate analysis and non-clinical testing must demonstrate that the safety controls are adequate to ensure safe use of the device and prevent user falls from the device in the event of a device failure; (2) Appropriate analysis and non-clinical testing must demonstrate the ability of the device to withstand the rated user weight load with an appropriate factor of safety; (3) Appropriate analysis and non-clinical testing must demonstrate the longevity of the device to withstand external forces applied to the device and provide the user with an expected service life of the device; (4) Appropriate analysis and non-clinical testing must demonstrate proper environments of use and storage of the device to maximize the longevity of the device; (5) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of ANSI/AAMI/ES60601-1, “Medical Electrical Equipment—Part 1: General Requirements for Basic Safety and Essential Performance,” and ANSI/AAMI/IEC 60601-1-2, “Medical Electrical Equipment—Part 1-2: General Requirements for Basic Safety and Essential Performance—Collateral Standard: Electromagnetic Disturbances—Requirements and Tests”) must validate electromagnetic compatibility and electrical safety; (6) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of ANSI/AAMI/ISO 10993-1, “Biological Evaluation of Medical Devices—Part 1: Evaluation and Testing Within a Risk Management Process,” ANSI/AAMI/ISO 10993-5, “Biological Evaluation of Medical Devices—Part 5: Tests for In Vitro Cytotoxicity,” and ANSI/AAMI/ISO 10993-10, “Biological Evaluation of Medical Devices—Part 10: Tests for Irritation and Skin Sensitization”) must validate that the skin-contacting components of the device are biocompatible; (7) Appropriate analysis and non-clinical testing (such as that outlined in the currently FDA-recognized editions of IEC 62304, “Medical Device Software—Software Life Cycle Processes”) must validate the software life cycle and that all processes, activities, and tasks are implemented and documented; (8) Appropriate analysis and non-clinical testing must validate that the device components are found to be non-flammable; (9) Appropriate analysis and non-clinical testing must validate that the battery in the device (if applicable) performs as intended over the anticipated service life of the device; and (10) Adequate patient labeling is provided to the user to document proper use and maintenance of the device to ensure safe use of the device by the patient in the intended use environment.
