Manufacturer Narrative

This event has been recorded by zimmer biomet under (b)(4).Once the investigation is completed, a follow-up/final report will be submitted.

Event Description

It was reported that this unit is marked as "broken" and has been out of service for some time.Level sensor float stuck in top position causing cart to read full which will not allow suction.The vacuum would not start.The event occurred before surgery.This occurred in both cylinders.There was no adverse event reported as a result of this malfunction.

Manufacturer Narrative

This event has been recorded by zimmer biomet under (b)(4).The technician found that the level sensor float was stuck due to bio burden.The cylinder was cleaned and the float was freed.The customer was informed of the importance of full soaks.The unit was tested to verify proper operation and returned to service.The level sensor is required to read and report fluid level in the cylinders in order for the unit to function as intended.A clog due to biomaterial or a foreign object will cause a blockage in the cylinder and impaired use of the drain; this failure will cause inaccurate readings from the level sensor, as the residual fluid unable to drain may not be accurately accounted for by the component.Mechanical failure from loosening can occur as the level sensor is mounted in the base of the cart with an o-ring and held in place with two setscrews.Over time and through continuous use, the screws can loosen, allowing the sensor rod to move within the cylinder and prompting errors.The level sensor float can fail through continuous use and wear as well.Bioburden can build up on the level sensor float or magnet, or the level sensor float could crack, both failure modes can disrupt the buoyancy of the float, causing incorrect fluid level readings.Tandem and range errors occur due to user error.Tandem errors populate when the device¿s software detects an incorrect fluid level measurement in one or both cylinders often when the user introduces fluid into the cylinder after the pump has shut off due to the cylinder being full.Tandem errors are a result of fluid levels increasing without the vacuum system being turned on.Due to a range of external (non-design / non-manufacturing related) variables potentially impacting the component, identifying definitive causes for each level sensor failure is generally not possible.Review of the information provided during the investigation determined there is no further actions needed at this time.Level sensor failures are a well-known failure mode, with no allegations of harm or injury to a patient.This complaint will be tracked and trended for any adverse trends that may warrant further action.
