Embodiment Construction

[0040] Referring to the accompanying drawings, the drawings are shown to illustrate preferred embodiments of the present invention, but not to limit the present invention. Such as figure 1 Shown is a nasogastric tube 20 according to a first embodiment of the present invention. Wherein the nasogastric tube 20 is clean, flexible, hollow and made of latex, silica gel, nylon, polyurethane or polyvinyl chloride. The nasogastric tube 20 has a length of 75 to 100 cm and a diameter of 8 to 18 catheter diameters (French). The nasogastric tube 20 has two ends, a proximal end 22 that remains outside the patient's body, and a distal end 24 that is placed in the patient's stomach. The proximal end 22 is provided with a connection for suction or injection. The distal end 24 is provided with a blunt tip and also has a drain port 26 for evacuation which can extend around the entire circumference of the tube and along the most distal 5 to 10 cm of the tube. Such as figure 2 As shown, the...

Abstract

A nasogastric (NG) tube for placement into the lumen of the stomach by way of a nostril having a tapered tip, a lubricious coating, and one or more expandable balloons that surround drainage ports. During insertion into the stomach the tapered tip and lubricious coating facilitate the tube traversing the patient's nasopharynx and esophagus with reduced injury. During insertion the expandable balloons are maintained in a low profile state but upon reaching the stomach lumen are expanded to a high profile state and improve drainage by pushing the stomach wall away from the drainage ports.

Description

technical field [0001] The present invention is in the field of medical devices and relates to nasogastric tubes, which are used in the process of introducing or removing material from the gastrointestinal tract through the nasal or oral cavity by means of insertion of an elastic tube . Background technique [0002] The Levin nasogastric tube is the most widely used nasogastric tube today. Consists of a long, flexible, single-lumen tube with a drainage port at one end that uses suction to remove stomach contents. The medical industry uses tens of thousands of nasogastric tubes each year for various purposes including: removal of gases and fluids from the stomach and gastrointestinal tract, diagnosis of gastrointestinal diseases, treatment of blockages or blockages, for irrigation or alternate delivery Substances such as drugs and nutrients. The primary tube used for irrigation is usually smaller and softer than the nasogastric tube and is considered a different type of me...
