Customer reported that the strain relief tube (which connects the patient tube to the drain) was discovered with a hole in it after the drain had been used for some time.Pictures of the tube provided by the customer look like it was crushed.The reporter states that the patient's bed was lowered during the night and the damaged tube was discovered early in the morning, so it is probable that the tube was caught in the mechanism of the bed and was crushed.The tube was returned for evaluation.It was observed that the corrugated plastic around the tube is broken and torn.Some edges of the break are stretched, as if pulled apart with great force.The damage appears consistent with the proposed theory that the tube was caught in the mechanism of the bed as the bed was lowered.Based on the details provided by the customer and the information reviewed during the investigation, it was confirmed that the device was damaged, however, it was not confirmed that the damage occurred during manufacturing or shipment of the product.It was determined that the most probable cause of the damage is operational context.A dhr could not be completed because the lot number was not provided.However, based on the description of the complaint, it is unlikely that any material, manufacturing, equipment, or labeling issues contributed to this event.The ifu for this device provides instructions for how to properly set up and operate the drain.Complaint trending and the complaint history review found no related complaints.A review of cars/capas/ncrs/scars found nothing related to this complaint.The hazardous situation/harm is addressed in the harm hazards analysis document which assigns it a severity level of 1.This was determined to be appropriate based on the harm that was reported in the complaint.Complaint trending concluded that the actual occurrence level matched the anticipated occurrence level and there was only a single occurrence within the reviewed trending periods.No excursions were identified in trending.
