Abstract
The utility model relates to a reinforced nasopharyngeal air duct which is used by an anesthesia department to help a patient maintain smoothness of a respiratory tract during the perioperative period. The reinforced nasopharyngeal air duct comprises an elastic and flexible hollow conduit, an oblique angle opening is arranged at the front end of the hollow conduit, a flare opening is arranged at the tail end of the hollow conduit, and a spiral steel wire is wrapped in the wall of the hollow conduit. As the wall of the hollow conduit is reinforced through the arrangement of the spiral steel wire, the reinforced nasopharyngeal air duct has high pressing resistance, and a channel in an inner cavity of the air duct cannot be deformed before or after insertion. With convenient operation and good safety, the reinforced nasopharyngeal air duct can effectively ensure smoothness of the respiratory tract.
Description
Technical field
This utility model relates to a kind of patient of being used for of Anesthesia Department remains respiratory passage unblocked between perioperative reinforced nasopharynx airway.
Background technology
In anesthesia and the first-aid patients first aid process, setting up and keep the complete and unobstructed air flue of patient is the prerequisite that guarantees patient's normal ventilation and breathing, also is the prerequisite that guarantees patient safety and carry out anaphase.
For achieving the above object, need in air flue, insert dissimilar airways as the case may be, comprise oropharyngeal airway, reinforced nasopharynx airway, laryngeal mask snorkel, endotracheal tube or bronchus inner catheter etc.Like this, anesthesia person can initiatively grasp airway patency, implements control breathing.
The endotracheal intubation method has multiple, is mainly that the state of an illness needs or for intubate may patient design, can takes the circumstances into consideration to select for use.Reinforced nasopharynx airway is applicable to Intraoral-procedures or the patient who dissects opening difficulties such as deformity is arranged.
Reinforced nasopharynx airway is a kind of possess elasticity, soft hollow conduit, the about 15CM of length, and profile is similar to tracheal intubation, and the short and blunt circle of its front end angle is not with air bag.But existing reinforced nasopharynx airway in actual applications, has the not good defective of inconvenient operation, security performance.Trace it to its cause, discovery is because the anti-flat flat property of existing reinforced nasopharynx airway is bad, and during insertion, flat flat phenomenon easily takes place reinforced nasopharynx airway, finally causes occurring the not good problem of inconvenient operation, security performance.
The utility model content
In order to address the above problem, this utility model provides a kind of anti-good, easy to operate reinforced nasopharynx airway of flat flat property.
To achieve these goals, the technical scheme that this utility model adopted is:
A kind of reinforced nasopharynx airway comprises an elasticity, soft hollow conduit, and the front end of this hollow conduit is provided with angle of chamfer opening, tail end is provided with horn mouth, is coated with spiral wire in the tube wall of described hollow conduit.
As the further setting of such scheme, described hollow conduit selects for use the polrvinyl chloride that does not contain DEHP to make, and it is that the 304 rustless steel steel wires of 0.1mm are made that spiral wire is selected diameter for use.Wherein, DEHP is the abbreviation of the own ester of phthalic acid (diethyl).
The reinforced nasopharynx airway of this utility model, its tube wall is strengthened by spiral wire is set, and anti-flat flat property is good, it can be out of shape with insertion back breather bore passages during insertion, easy to operate, it is unobstructed effectively to ensure respiration, and safety in utilization is good.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to enlarged diagram.
The specific embodiment
As shown in Figure 1, 2, a kind of reinforced nasopharynx airway of this utility model comprises an elasticity, soft hollow conduit 1, and the front end of this hollow conduit 1 is provided with angle of chamfer opening 2, tail end is provided with horn mouth 3, and is coated with spiral wire 4 in the tube wall of hollow conduit 1.Wherein, hollow conduit 1 selects for use the polrvinyl chloride that does not contain DEHP to make, and it is that the 304 rustless steel steel wires of 0.1mm are made that spiral wire 4 is selected diameter for use.
The Anesthetist because this reinforced nasopharynx airway resists flat property height, need rotate and slowly insertion when intubate according to the reinforced nasopharynx airway of patient body weight and the suitable specification of nasal cavity situation selection, conveniently, and can be flat not flat.
Select unobstructed side nostril to insert; Reinforced nasopharynx airway surface need be coated with the medical lubricant (conduit glue) to contain local anesthetic earlier; The length of reinforced nasopharynx airway generally can be pressed nose to the distance of external auditory meatus and be calculated; Reinforced nasopharynx airway must insert along inferior nasal meatus, and insert action should be softly, slowly, meet resistance and should not insert by force, can rotate reinforced nasopharynx airway slightly and after the non-resistance sense, advance continuing.In putting the pipe process, no matter how crooked pipe shaft is, and its inner tract because the effect of spiral wire 4 remains constantly flat flat phenomenon can not take place, guarantees the safety that reinforced nasopharynx airway uses.
In a word, this utility model is simple in structure, and the suitability is strong; Easy and simple to handle, safety in utilization is good.
The foregoing description only is used to the inventive concept of the present utility model of explaining, but not to the qualification of this utility model rights protection, allly utilizes this design that this utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
Claims (2)
