Description

Anti-reflux nasogastric tube for blocking esophageal-tracheal fistula

Technical Field

The utility model relates to a nasogastric tube for medical apparatus, in particular to a nasogastric tube for preventing reflux and blocking esophageal-tracheal fistula.

Background

Reflux aspiration is common in medical activities, for example, critically ill patients are often accompanied with gastrointestinal dysfunction such as vomiting, especially in elderly patients with cerebrovascular diseases, autonomous cough and expectoration are weak, aspiration pneumonia can be caused, fatal percussion is brought, and continuous negative pressure aspiration can prevent reflux, but the nutritional requirements cannot be guaranteed; for stomach and esophagus operation patients, the cardia is loose or the esophagus is shortened due to the change of the structure, the risk of backflow and aspiration is extremely high, and even if the stomach content is extremely little, the risk of backflow and aspiration exists in the process of ordinary stomach tube nutrition; esophageal and tracheal fistulas are often caused after radiotherapy of patients with esophageal or thoracic tumors, most patients are often subjected to operation and airway stent implantation treatment unconditionally due to poor foundation, and only a few hospitals have treatment experience of equipment and personnel, so that the prognosis is poor. Such as above, the common stomach tube can not solve the problems and can not meet the clinical requirements.

Disclosure of Invention

To the not enough and drawback that current nasogastric tube exists, the utility model aims to provide a can effectively resist the reflux and also can feed safely simultaneously, also can block off the nasogastric tube of esophagus trachea fistula in addition.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted as follows:

the nasogastric tube for preventing backflow and blocking the esophageal-tracheal fistula mainly comprises a silica gel nasogastric tube body, wherein an opening at the upper end of the tube body can be used for connecting a negative pressure drainage ball and feeding food, and a rubber plug is arranged at an opening of the tube body.

The silicone tube is provided with an inner guide wire which can be placed into the silicone tube from an opening at the upper end of the tube body, so that the success rate of inserting the nasogastric tube can be improved.

The body middle section has an inflatable balloon, be rectangular butterfly type after aerifing, the long 12cm of balloon, can effectively prevent the refluence, 12 cm's length can cover esophagus and tracheal boundary distance completely simultaneously, the sacculus lower extreme is located 28cm department on the body end, be located between pharynx esophagus stenosis and diaphragm stenosis when having guaranteed that the sacculus aerifys, card in physiology stenosis department after having avoided the sacculus to aerify, cause ischemic necrosis, even 28 cm's apart from the fistula position is on the upper side, also can guarantee that the stomach tube end is located in the stomach.

The balloon catheter is connected with the one-way inflation valve through the hollow stomach tube body, the pressure in the balloon can be measured after the one-way inflation valve is connected with the pressure sensor, the pressure of the monitoring balloon is located between 15 mmHg and 30mmHg, the backflow risk caused by insufficient pressure of the balloon is avoided, and mucosal ischemic necrosis caused by overhigh pressure of the balloon is also avoided.

The drainage tube capable of continuously sucking negative pressure is arranged above the balloon, the head end of the drainage tube can be connected with a negative pressure device, the tail end opening of the drainage tube is positioned above the balloon, the opening is positioned on the outer side of the stomach tube body, and the continuous negative pressure suction ensures the accumulation of saliva and secretion at the upper end when the balloon is opened, so that the liquid at the upper end is effectively prevented from flowing back to cause mistaken suction.

The tail end of the stomach tube is provided with an opening, and the side wall at the tail end of the stomach tube is provided with four side holes, so that obstruction caused by opening blockage can be effectively prevented.

Scales are marked on the stomach tube body, so that a tube placer can know the placing scales.

The utility model has the advantages of it is following and beneficial effect: compared with the common nasogastric tube, when the nasogastric tube is placed in a determined position, the saccule can be opened to block the esophagus, backflow and aspiration can be effectively prevented, meanwhile, negative pressure suction can be continuously performed above the saccule, secretions flowing into the esophagus in the mouth can be effectively cleared, and backflow and aspiration can be further prevented; in addition, the balloon pressure can be measured, so that the safety and effectiveness of long-time retention are ensured; because the sacculus is rectangular butterfly type, saliva and secretion can effectively be stayed to the recess of its upper segment, through the negative pressure suction drainage esophagus, the recess of hypomere can effectively prevent the stomach content from backflowing, and the sacculus is longer, consequently when the patient has the unconditionally effective intervention of esophagus trachea fistula, can give this stomach tube to put into, on the one hand can effectively provide enteral nutrition, on the other hand effectively prevents the backflowing, and temporary shutoff fistula, prevent the disease progress, win the time for the disease healing, to because of basic condition is poor, unconditionally carry out the operation or put into the patient of esophagus support, can regard as the secondary treatment of selecting, and easy operation, the risk is little, the gain of benefit is high.
