This is a replacement part for a medical/nursing care suction device. It is a part of the bottle lid for the suction device. The first photo shows an image of all the parts, and this is one of them. The second photo shows the lid turned upside down. The third photo shows the top of the lid. Please check the product name, product code, and part number in the third photo. Purchased on January 6, 2025. I accidentally purchased the wrong model... Returns and exchanges were not possible, so I am listing it. It is unopened and in the same condition as when it arrived. Due to hygiene concerns, we do not accept returns after delivery. I am not currently considering a price reduction. Please consider this for your part replacement.
