A nasogastric tube insertion system (100) comprises a nasogastric tube (110), a guide element (120), and an inserter element (130). The inserter element has a slim, elongate main body'i a handle attached to the body, and an anatomicall curved insertion section. The guide element comprises a swallowable weight attached to a cord, string, monofilament line, tube, or other similar line. The swallowable weight may be ablative in the presence of stomach fluids or may be deflated to allow the guide element to be removed while the nasogastric tube remains in place. The inserter element is inserted through the patient's nasal passages and optionally into the oropharynx. The weight is released and the patient swallows it into the stomach. The guide element is threaded through the guide element retaining structure, and the nasogastric tube is safely inserted along the guide element into the patient's stomach. |
