This event or problem below is as described by the user facility: event or problem initially found by user facility on (b)(6) 2016.Event or problem reported to reliance medical products, inc.On 04/14/2016 as follows: (b)(6), biomed technician from (b)(6) contacted reliance medical products that the doctor initially stated, "their 7000 exam chair is raising up without pressing any of the switches randomly", resulting in the chair being raised up on its own.He was notified that this occurrence of the chair raising without requesting it to do so has led to the injury of a male elderly patient.He was told that the patient's top of his hand on his lap was bruised from being pinched / bruised under the slit lamp table as the chair continued to raise on its own.Also, the physician was notified by the patient's daughter that the injured patient's wound opened / skin split and became infected when she returned to the office.Event or problem update reported to reliance medical products, inc.On 04/21/2016: (b)(6), clinical manager of the retinal division response per (b)(6) evaluation: as a precautionary measure (b)(6) replaced the circuit board in the chair but the problem still continued.He removed the foot switch and the chair control cable from the chair and the problem seems to have gone away.This 7000 chair has been removed from service until (b)(6) is able to identify the problem.(b)(6).(b)(6) called reliance medical products back stating, "he found a small piece of a staple oddly punctured through the membrane of the up side of the foot switch".(b)(6) believes that the staple in the up side of the footswitch membrane could have caused the problem.(b)(6) is continuing to test the chair to ensure it is safe to return to service.(b)(6) is working to try to solve the problem.This exam chair has been removed from the heavily used patient area.(b)(6) found a very probable cause of the equipment failure in the foot pedal for the 7000 exam chair.There was a small fragment of metal that made its way into the foot switch pedal and pierced the switch membrane at the exact spot of the elevate button for the exam chair.This would cause the two sides of the switch to be closer together than they should be at rest, thus making it more probable that the slightest movement would cause the chair to rise randomly.I have since changed the membrane in the foot pedal, but have yet to test on the exam chair.
