Otsuka Pharmaceutical Semi-Solid Nutritional Agent Pressure Bag Pressure bag for efficient supply of nutritional agents Manual Pressure Infusion Regulator Product Name: Semi-Solid Nutritional Agent Pressure Bag Model: Manual Pump Set Expiration Date: 2026-05 Thank you for viewing. This is a device for administering semi-solid enteral nutrition by compressing it with a pressure bag. It uses a bag pressurized by external air (air pushed out by a manual pump) to crush the container of the nutritional agent and push it out. It allows for easy administration of nutritional agents. The manual pump makes it easier to apply pressure. Simply insert the nutritional agent pack and apply pressure. No need to forcefully squeeze the pack. I have kept it carefully as a spare, so it has never been used. I stored it carefully in its original packaging, new and unopened, but I opened it for inspection and took photos because there was some staining on the outer bag. The product was only touched during the photography and is clean. Please understand that there is some staining on the outer bag. It will be shipped in a slightly larger size to prevent damage.
