Description

Prevent mistake suction inlet pharynx air vent

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to prevent mistake suction inlet pharynx air vent.

Background

The oropharyngeal airway is a non-tracheal catheter airway, and is a simple and economical airway aid. The oropharyngeal airway has various models, when in use, the appropriate model is selected according to the specific condition of a patient, the length of the oropharyngeal airway is easy from incisors to mandibular angle, the tongue tenesmus can be prevented, the airway can be opened rapidly, and a temporary artificial airway can be established; the appearance is "S" shape, including flange, bite-block part and pharynx bending part, the flange: the outer edge (namely the flange) protruding from the outer end of the mouth can prevent swallowing and inserting too deeply; a bite block portion: the width of the occlusal part of the cushion part contacting with the teeth is enough to contact with two to three teeth, so that the occlusal pressure of the teeth can be evenly distributed on the contacted teeth; pharyngeal bend: the curvature of the inner end of the pharynx bending part is suitable for the anatomy of the mouth, tongue and pharynx back. When the utility model is used, the secretion of the oropharynx part is cleared firstly, the pharyngeal bending surface of the oropharynx air pipe is inserted into the palate part, when the head end is close to the rear wall of the oropharynx part through the uvula (uvula), the pipeline is rotated by 180 degrees, the pipe is pushed downwards to a proper position, and the tail end of the oropharynx air pipe protrudes out of incisors (incisors) by 1-2 cm. The patient suffering from hiccup risk such as patients with more gastric contents is forbidden, because vomit can directly enter into oropharyngeal airway to cause aspiration of the patient when intubation or the patient vomits due to negative pressure increase and the like, the patient is choked to cough, and the patient can suffocate to die in serious patients; in addition, the existing oropharynx air duct needs to be fixed to the face of a patient through tape pasting, the skin of the patient is easily damaged through tape pasting, the fixing effect is poor, and the oropharynx air duct is easily displaced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provide a false suction prevention pharynx air duct which can prevent the regurgitation of the gastric contents of the patient from causing the false suction.

In order to solve the technical problem, the utility model adopts the following technical scheme: an anti-mistaken-suction-port pharyngeal airway comprises a lip baffle and an oropharyngeal airway body, wherein a mounting hole is formed in the middle of the lip baffle, a short sleeve is fixed at the mounting hole of the lip baffle, and an internal thread is formed in the inner side wall of the lower portion of the short sleeve;

the oropharynx air duct body is provided with a vertical part and a bending part, the periphery of the top end of the vertical part is fixedly provided with a mounting ring, the periphery of the mounting ring is provided with an external thread matched with the internal thread at the lower part of the short sleeve, the lower part of the vertical part is provided with a bite block structure, and the outer surface of the bite block structure is provided with a soft rubber layer; the oropharynx air duct body is internally provided with a trachea channel and a stomach tube channel, the lower port of the trachea channel is positioned on the inner side of the lower end of the bending part, and the lower port of the stomach tube channel is positioned on the outer side of the lower end of the bending part; an endotracheal tube is inserted in the tracheal channel, and a gastric tube is inserted in the gastric tube channel.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the utility model can prevent the device from moving left and right as a whole and avoid the oropharynx air duct body from sliding down by additionally arranging the lip baffle; secondly, a bite block wrapping the soft rubber layer is arranged on the oropharynx air duct body, so that teeth are prevented from being damaged, and the oropharynx air duct is prevented from being occluded when the teeth are occluded; a certain angle is formed between the stomach tube and the tracheal catheter, so that the stomach content is prevented from directly entering the trachea; the utility model has the advantages of reasonable design of overall structure, it is convenient fixed, cause the mistake when preventing that stomach content from palirrhea from inhaling.

Detailed Description

As shown in figure 1, the anti-mistaken-suction-port-preventing pharyngeal airway of the utility model comprises a lip baffle 1 and an oropharyngeal airway body 2, wherein the middle part of the lip baffle 1 is provided with a mounting hole, a short sleeve 3 is fixed at the mounting hole of the lip baffle 1, and the inner side wall of the lower part of the short sleeve 3 is provided with an internal thread;

the oropharynx air duct body 2 is provided with a vertical part 4 and a bending part 5, the periphery of the top end of the vertical part 4 is fixed with a mounting ring 6, the periphery of the mounting ring 6 is provided with an external thread matched with the internal thread at the lower part of the short sleeve 3, the lower part of the vertical part 4 is provided with a bite block 7 structure, and the outer surface of the bite block 7 structure is provided with a soft rubber layer; the oropharynx air duct body 2 is internally provided with a trachea channel and a stomach tube channel, a lower port 8 of the trachea channel is positioned on the inner side of the lower end of the bending part 5, and a lower port 9 of the stomach tube channel is positioned on the outer side of the lower end of the bending part 5; an endotracheal tube 10 is inserted in the tracheal passage, and a gastric tube 11 is inserted in the gastric tube passage.

The novel technology comprises a lip baffle 1 and an oropharynx air duct body 2, wherein the lip baffle 1 is provided with a short sleeve 3, a vertical part 4 of the oropharynx air duct body 2 is in threaded connection with the lower part of the short sleeve 3 through an installation ring 6 when the oropharynx air duct is used, then the oropharynx air duct is inserted, the lip baffle 1 is placed between a lip and a tooth, the fixing is convenient, the left and right movement of the lip baffle is avoided, the oropharynx air duct body 2 is prevented from sliding downwards, and therefore the lip baffle 1 plays a good role in fixing the oropharynx air duct body 2 and avoids the left and right movement or sliding downwards; the oropharynx air duct body 2 is provided with a bite block 7 which is externally covered by a soft rubber layer, so that the teeth are prevented from being damaged, and the oropharynx air duct is prevented from being occluded when the teeth are occluded;
