Description

Prevent inhaling nasopharynx air vent by mistake

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to prevent mistake and inhale nasopharynx air vent.

Background

Nasopharyngeal airway (NPA) is also called nasopharyngeal airway, is a simple and cost-effective extra-glottic airway device, and is mainly used for relieving upper respiratory tract obstruction caused by glossoptosis and the like. The nasal cavity type. The double-nostril type nasal cavity is formed by connecting the middles of two nasopharynx air ducts without cuffs through a joint. The traditional NPA is similar to a tracheal catheter in shape, and the oblique mouth of the pharyngeal end is short and round, so that the stimulation to the pharyngeal portion can be reduced. The nose end is provided with a flange which can prevent the nose end from falling into the nasal cavity. The NPA is made of medical polyvinyl chloride materials, has moderate hardness, can reduce the damage of the NPA to nasal mucosa, and cannot be twisted and folded in vivo to cause the stenosis of a tube cavity. The ideal contraposition after the nasopharynx air duct is put into is: after inserting the pharyngeal cavity from patient's nasal cavity, the pharynx end is located 0.5 cm department outside the glottis, and the wall behind the pharynx can be supported to counterpoint like this to remove upper respiratory tract and obstruct, keep the air flue unobstructed. The length of the nasopharyngeal airway is more important than the diameter of the nasopharyngeal airway, and the current method for clinically guiding the selection of the nasopharyngeal airway model is mainly selected according to the length, namely the depth of a person to be placed, and is generally divided into two types: one is to measure the length from the tragus to the tip of the nose plus 2.5 cm; another is to measure the length from the mouth of the ear canal to the tip of the nose. In the prior art, before people put, the surface of the nasopharyngeal airway is coated with lubricant such as lidocaine gel or liquid paraffin for facilitating the placement. Placing in the anterior position: the mandible of a patient is firstly lifted forwards and upwards to ensure that an air passage is unobstructed and the patient can be conveniently placed in the nasal cavity, the patient can be placed in the nasal cavity by selecting the side with unobstructed nasal cavity, usually the right nostril is preferred, and when the placement is not convenient, the patient can be placed in the left nostril. And (3) carrying out embedding operation: the superior pen-held nasopharyngeal airway can be inserted along the inferior nasal passage in a direction completely perpendicular to the face, and the flange of the pen-held nasopharyngeal airway can reach the nostril. The existing nasopharynx air duct is simple in structure and only has the function of assisting in ventilation, and is forbidden for patients who are full in stomach or who possibly have hiccup, because the intubation tube stimulates the throat part in the intubation process, the patients often feel nausea and vomit, if the stomach content reversely flows through the esophagus and enters the trachea, the patients possibly inhale by mistake, the patients possibly suffocate and die seriously, the existing nasopharynx air duct is simple in structure and cannot prevent the stomach content from reversely flowing into the trachea, the insertion depth of the existing nasopharynx air duct is inconvenient to fix after the existing nasopharynx air duct is inserted, the insertion depth is easy to change after the existing nasopharynx air duct is inserted, and the duct is displaced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nasopharyngeal airway which is convenient to fix and can prevent the gastric content from flowing back to the trachea to prevent the aspiration, aiming at solving the defects in the prior art.

In order to solve the technical problem, the utility model adopts the following technical scheme: the anti-aspiration nasopharynx air duct comprises an air duct and a pressure reducing pipe, the upper parts of the air duct and the pressure reducing pipe are fixed through a fixing ring, the fixing ring is connected with two tying ropes, the air duct and the pressure reducing pipe are arc pipes, the outer side of the lower end part of the air duct is connected with the pressure reducing pipe through viscose, an air bag is arranged on the periphery of the pressure reducing pipe and correspondingly located on one side of the viscose, a second air vent hole is formed in the inner side of the lower end part of the air duct, the upper end of the air duct is open and is a first air vent, the upper end part of the air duct is connected with an oxygen inhaling pipe, an inflation channel is arranged in the pipe wall of the pressure reducing pipe, the upper end part of the pressure reducing pipe is connected with an inflation pipe, the inflation pipe inflates the air bag through the inflation channel, and the lower end of the pressure reducing pipe is located below the lower end of the air duct; the pipe wall of the breather pipe is provided with length scale marks.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: when the novel technology is used, the inner side surface of the vent pipe faces upwards when the vent pipe is inserted, the vent pipe is connected with the decompression pipe through viscose after the vent pipe is inserted to a certain depth according to the measurement method of the prior art, the vent pipe is convenient to insert, the lower ends of the vent pipe and the decompression pipe are forked when the vent pipe is inserted, then the vent pipe and the decompression pipe are inflated through the inflation pipe, the air bag is inflated to expand to enable the lower end of the vent pipe and the decompression pipe to be forked, the vent pipe protrudes forwards according to the anatomical position, the lower end of the decompression pipe is connected with the esophagus inlet, the air bag plays a role in closing the esophagus inlet, the air bag plays a certain blocking role when the reflux of gastric contents occurs, the decompression pipe is a communicated pipeline, and when the reflux of the gastric contents occurs, the air and liquid can be discharged through the decompression pipe to play a certain decompression role; after the device determines the insertion position, the fixing ring is fixed through a tether; the novel technology can reduce the possibility of mistaken suction during the reflux of the gastric contents, and is convenient to fix the depth of the inserted pipeline and safer and more convenient to use.
