The autopulse lifeband was returned to zoll on 11/03/2014 for investigation.Investigation results as follows: the lifeband was not received in its original packaging.The compression pad was received dirty with blood stains all over the top and bottom of the pads and belt guards.The reported issue of the lifeband being twisted was confirmed; inspection revealed multiple creases and twists on the surface of the belt guard.The rub guard liner that connects to the top compression pad of the left belt guard cap was completely torn, ripped and broke apart from the cover plate.It appeared the unit had been used and these damages were due to wear and tear.Functional testing revealed that the right hinged skirt of the cover plate "snapped" into the retracted position.The hook caught the cam style tumbler securing the "butterfly clip" tightly.The left clip was broken and would not "snap" into the retracted position, thus confirming the reported complaint of the skirt hook not catching the cam style tumbler.With the condition of the unit as received being damaged and torn apart, additional functional testing with the test autopulse and mannequin could not be performed.The reported complaint was confirmed based on visual inspection of the left clip as well as the lifeband belt and compression pads.All lifebands are 100% inspected to ensure that there are no damages and that the clips function properly.Based on the condition of the returned unit, the cause of the damages observed to the lifeband have been determined to be handling damage sustained during use or storage.
