Description

Safe intermittent tube-placing feeding anti-backflow nutrition tube

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a safe intermittent tube-placing feeding anti-backflow nutrition tube.

Background

Common methods for enteral nutrition in head and neck tumor patients, including nasopharyngeal carcinoma, are nasogastric tube and percutaneous gastrostomy. The short-term transition patients pass through the nasogastric tube, but the nasogastric tube not only affects the appearance and causes discomfort, but also affects the swallowing function, and can cause the damage of esophagus and gastric mucosa and nasal cavity, hiccup, reflux and even inhalation pneumonia, and the patients sometimes pull out the tube by themselves; and gastrostomy is mainly applied to patients who need long-term enteral nutrition, and has large wounds.

Intermittent tube placement refers to a nutrition supply method by inserting a nutrition catheter (soft silicone tube is selected) into the upper section of esophagus (25 cm from the teeth of the door) through the mouth before a patient eats, injecting prepared fluid diet, water or medicine with a feeder, and pulling out the catheter immediately after the injection. The operation is simple and easy, can avoid the complications of oral cavity and upper respiratory tract infection, is a comfortable and effective nutrition support way, and can provide safe and comprehensive nutrition support for patients. Clinically, it has been applied to patients with dysphagia after treatment of cerebral stroke and head and neck diseases. Compared with a nasogastric tube, the nasogastric tube does not need to be left for a long time, the intubation is used for feeding during feeding time, the pipeline is not left at other times, the beauty is not affected, the self-esteem of a patient is respected, and the patient can return to families and society better. The oral cavity is inserted into the mouth, the root of the tongue is stimulated when the oral cavity reaches the root of the tongue, the tension of the hyoid muscle is enhanced by intermittently inducing swallowing reflex, and the laryngeal mask is beneficial to the lifting movement of the laryngeal mask, so that the recovery of the coordinated movement of swallowing is induced by matching with the active swallowing function training, the length from the mouth to the upper esophageal tube is shortened, the respiratory tract and the esophagus of a patient are prevented from being damaged, and the comfort level of the patient is obviously improved. The current intermittent catheter is a disposable 16F latex catheter which is widely used clinically, the length and the material of the catheter are suitable, but the catheter is originally used for draining urine, and a disposable sterile catheter is obviously written on a packaging bag of the catheter and used for feeding, so that the acceptance degree of a patient is influenced, and part of patient feedback can feel psychological interference on the identification of the catheter. The surface of the urinary catheter is smooth, the urinary catheter is easy to shift and slip after being placed, the urinary catheter is provided with an opening at the side edge, and most of foods injected by many household patients are homemade fluid foods which are too viscous and easy to block the catheter.
