Optumhealth Care Solutions, LLC issued an Urgent Device Recall by the Manufacturer of Nimbus II Pump notice to its consignees on 04/18/2024 via email Delivery/Adobe Sign and UPS Next Day Air. The notice sent an electronic link to the press release and stated that a nurse would be contacting the consignee to schedule a pump replacement, including a home visit to instruct the patient on the use of the new pump. In the meantime, if you have any issue with your current Nimbus II pump, please contact your nurse right away to prioritize your pump replacement. Additionally, the manufacturer recommends in its recall notice that you take the following actions, so please be aware and comply with them until your Nimbus II pump has been replaced: 1. When replacing batteries, only new batteries should be used. Care should be taken to ensure that old and new batteries are not confused when completing the replacement. 2. The battery should not be cycled (turned on/off) to clear the occlusion alarm. If the occlusion alarm cannot be cleared, a new pump should be used. Silencing the alarm does not clear the occlusion. 3. Due to the potential ambulatory use of the pump, you may carry the drug product dispensing pouch in a carrying pack. Please note that impeding the tubing set or placing pressure on the device (leaning against it, sitting on it) may cause the device to malfunction. 4. If you note any difficulties or abnormalities with the pump or accessories, immediately discontinue use of the pump and notify your Optum nurse or health care provider.
