Description

Nasopharyngeal airway

Technical Field

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

Background

The nasopharynx air duct is a simple and convenient extra-glottis air breather, is used for relieving upper respiratory tract obstruction, keeps the air duct unobstructed, is suitable for the patient that the lower jaw is very tight, the tooth closes tightly, puts into endotracheal tube difficulty through the mouth, carries out unilateral lung to ventilate when needing to operate one side lung to thoracic surgery and also is suitable for. The existing nasopharynx air duct is mostly inserted into an upper respiratory tract through one side nostril, then is fixed to the face by an adhesive tape, and is fixed by pressing the hand to the other side nostril, so that oxygen entering through the nasopharynx air duct is prevented from being directly exhaled through the other side nostril. The prior art is inconvenient to fix, can not be used by patients with facial trauma, burn, allergy and the like, and is inconvenient to use by manually pressing nostrils at the other side, and the pressing effect is not ideal.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nasopharynx air duct which can be applied to special patients and is convenient to use and press, for solving the defects in the prior art.

In order to solve the technical problem, the utility model adopts the following technical scheme: the nasopharynx air duct comprises a nasopharynx air duct body and a nasopharynx plug part, wherein a medicine injection inner channel is arranged in the nasopharynx air duct body, the rear end part of the nasopharynx air duct body is connected with a breathing machine loop pipe interface, the rear end part of the nasopharynx air duct body is connected with an oxygen interface, a medicine injection interface and a carbon dioxide measurement interface, the medicine injection interface is connected with the medicine injection inner channel, and the front end of the nasopharynx air duct body is provided with a plurality of round holes;

the nose plug piece comprises a round platform barrel-shaped nose plug, a rubber layer is arranged on the outer side of the nose plug, an air bag body is arranged on the outer side of the rubber layer, an air injection interface is arranged on the air bag body, and a first bonding paste and a second bonding paste are connected to the nose plug; the two ends of the nasal plug are plugged by the soft membrane.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the novel technology has comprehensive functions, can block the nostrils on the opposite side, does not influence the retention of the nasogastric tube of a patient, prevents the air leakage of the nasal plug by the air sac body, and has good use effect because the soft membrane of the nasal plug is convenient to inject the medicine in the trachea through the nasopharynx air duct.
