Evaluation results : evaluation of the returned canopy found an open slider in a patient access area which could allow the unintentional patient escape.In addition, there was a 1/2 inch tear on the front side window.If the zipper slider body is bent open (i.E., the mouth is wider than manufacturing specifications) it can prevent the slider from properly engaging the zipper teeth.In areas where the slider engages the teeth, the zipper is secure and cannot be opened.However, if the teeth do not engage it can potentially leave an unsecured area.Applying pressure directly to the unsecured area will reveal the breach, which is why the user manual advises caregivers to apply direct pressure along the entire length of the zipper.In order for an open slider to potentially contribute to patient egress, the following must occur: the slider does not engage the teeth, the caregiver does not properly check the zipper prior to leaving the patient unattended, and the patient identifies the unsecured area and exits the bed.Following the ifu and standard servicing protocols, the user can identify any open sliders prior to use and return the bed for repair.In this case, there was no impact or consequence to the patient and the canopy was returned for servicing when the zipper issues were identified.Although the cause of the open slider cannot be confirmed, it is possible that an excessive amount of force was applied to the pull tab, which could have bent the slider body open.Service issues are trended and reviewed by management on a monthly basis.As part of this monthly review, trends and excursions above control limits will be assessed, documented and acted upon as warranted.No corrective or preventative actions are necessary at this time.Manufacture reference file # (b)(4).
