Description

Oropharynx breather pipe with air flue surface anesthesia function

Technical Field

The utility model belongs to the technical field of medical anesthesia equipment technique and specifically relates to an oropharynx breather pipe with air flue surface anesthesia function is related to.

Background

General anesthesia patient generally all need carry out trachea cannula, and first-selected needs use laryngoscope to choose the larynx then carries out trachea cannula among the trachea cannula process, produces the stimulation to epiglottis, glottis and air flue at the intubate in-process, causes obvious hemodynamic to increase.

At present, two methods for reducing intubation reflex exist, one is to use propofol, opium drugs, muscle relaxants and the like to increase the depth of anesthesia and inhibit intubation reflex; the second is to use an anesthesia apparatus to anesthetize the oropharyngeal and airway surfaces to reduce intubation reflexes. In the second method, topical anesthesia is usually performed by using a spray bottle or a laryngeal anesthesia tube, but the application has some disadvantages. The disadvantages are as follows: 1. the laryngoscope is used for assisting during surface anesthesia, the laryngoscope picks the throat to expose the glottis, and stimulation is performed on the epiglottis, the glottis and other parts in the assisting process; 2. the topical anesthetic effect is related to the technique of the anesthetist, which may cause insufficient topical anesthesia; 3. the watering can and the like can only perform surface anesthesia on the part above the air passage, and although the laryngeal anesthesia tube can perform surface anesthesia on the air passage, the curvature of the front-end catheter needs to be adjusted, and meanwhile, the glottis needs to be exposed more fully, so that stimulation to the glottis is increased; in addition, the laryngeal anesthesia tube may cause certain damage to the airway in the process of being inserted into the airway; as can be seen from the above, no suitable device is available at present, which can reduce the stimulation during intubation and can fully perform the surface anesthesia on the trachea and in the trachea.

The oropharynx air duct is also called as an oropharynx air duct, is a non-tracheal catheter non-invasive air duct commonly used in clinic, can prevent tongue from falling backward, quickly opens the air duct, and obtains an effective ventilation device. Oropharyngeal airway usually made of rubber or plastics, also can be made of metal or other elastic materials, the oropharyngeal airway commonly used in clinic is an oval hollow plastic tube, the appearance is "S" shape, including flange, bite-block part and pharynx bending part: 1. flange: the outer end of the mouth has a ring of protruding edges (i.e., flanges) to prevent swallowing and insertion too deeply. 2. A bite block portion: the width of the occlusal portion of the pad portion contacting the teeth is sufficient to contact two or three teeth so that the occlusal pressure is evenly distributed to the contacting teeth. 3. 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.

The oropharyngeal airway currently in use, the only ventilatory assist device, has no other function.

5. The oropharyngeal airway tube with airway surface anesthesia function of claim 1, characterized in that the outside of the bite block is further coated with a flexible pad.

6. The oropharyngeal airway tube with airway surface anesthesia function of claim 1, wherein the pharyngeal flexure comprises an upper flexure and a lower flexure which are inserted into each other; the lower curved portion comprising a first lower curved section and a second lower curved section, a distal end of the first lower curved section being hingedly connected to a proximal end of the second lower curved section; and a turnover driving mechanism is further arranged between the second lower bending branch part and the upper bending part and drives the second lower bending part to turn downwards compared with the first lower bending part.

7. The oropharyngeal airway with airway surface anesthesia function of claim 6, wherein the first lower curvature segment comprises a lower curvature segment A and a lower curvature segment B, the distal end of the lower curvature segment A is inserted into the proximal end of the lower curvature segment B, a common interlayer is arranged at the insertion position, and an extension driving mechanism is arranged in the common interlayer.

8. The oropharyngeal airway tube with airway surface anesthesia function of claim 6, further comprising a shield, the shield comprising: an upper protection subsection, a lower protection subsection, an outer sheathing part and an inner sheathing part; the two sides of the upper protection part and the lower protection part are mutually spliced in the vertical direction to form an oval tubular structure; the outer sleeving part and the inner sleeving part are flexible rubber tubes, the far end of the outer sleeving part is fixedly connected with the outer side walls of the upper protection part and the lower protection part, and the far end of the inner sleeving part is fixedly connected with the inner side walls of the upper protection part and the lower protection part.

9. The oropharyngeal airway with airway surface anesthesia as claimed in claim 8, wherein the lower protection part is provided with a hollow window, and the spraying opening sprays anesthetic drugs in both downward and rearward directions.

10. The oropharyngeal airway tube with airway surface anesthesia function of claim 8, wherein a booster roll is provided under the lower protection section, the extension direction of the booster roll is perpendicular to the extension direction of the lower protection section, and the booster roll partially protrudes from the lower surface of the lower protection section.
