Description

Intermittent oral-esophageal tube feeding double-cavity nutrition tube

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to intermittent type is through a mouthful to esophagus tube feeding two-chamber nutrition pipe.

Background

For patients who can not take food through mouth for various reasons, in order to ensure nutrition and moisture, a stomach tube is usually left in the patients, and the stomach tube is inserted into the stomach or jejunum through nostrils to provide moisture, medicines and liquid food for the patients every day so as to ensure nutrition. The general stomach feeding method is that a stomach tube is transnasally connected to an esophagus to a stomach for a long time and stays in the nose, the esophagus and the stomach of a patient, the indwelling stomach tube method increases food reflux, aspiration, pneumonia, gastritis, malnutrition and physical and psychological discomfort of the patient, can not exercise the swallowing function of the patient, and even causes the disuse swallowing disorder of the patient to be aggravated.

In order to cooperate with technological innovation in the field of medical care, an indwelling gastric tube is improved to be an intermittent oral-esophageal tube feeding method (IOE) to provide nutrition for a patient and exercise the swallowing capacity of the patient, meanwhile, the occurrence of complications such as aspiration, pneumonia and gastritis is reduced, and nasal discomfort, upper gastrointestinal discomfort and psychological disorder generated when the patient keeps the gastric tube are improved.

Most stomach tubes in the market are single-cavity latex stomach tubes or PVC (polyvinyl chloride) hoses of 60-80cm, and when the stomach tube is placed, a lubricant is firstly smeared on the placed part of the stomach tube for lubrication; the front end of the stomach tube needs to enter the stomach through the cardia, so that the cardia is in an open state for a long time and food backflow is easy to occur; the stomach tube is easy to displace outwards due to the peristalsis of the stomach of a patient or other factors, and the tube feeding operation is influenced; the stomach tube is left for a long time, and the trachea is prevented from being covered by epiglottis cartilage for a long time by a tube in the throat part, so that aspiration, pneumonia and discomfort of the nasopharynx part are easily caused; long-term indwelling gastric tubes can also lead to changes in patient image, mental depression and social involvement impairment; also, this method of indwelling gastric feeding does not exercise the swallowing function of the patient.

Therefore, a novel nutrition tube is developed, and the intermittent oral-to-esophageal tube feeding double-cavity nutrition tube solves the problems that before operation, paraffin oil is smeared, a stomach tube is easy to displace and cannot judge the depth of the stomach tube, the stomach tube cannot be used for X-ray development and block a food backflow channel, and is matched with an innovative tube feeding method, so that the working accuracy of nursing staff is improved, the treatment effect of dysphagia patients is improved, complications are reduced, and the swallowing function of the patients can be effectively exercised.
