Description

Novel anesthesia dental pad

Technical field

This utility model is a kind of surgical operation anaesthetic apparatus.

Background technology

Along with the development of modern anaesthesia technology, general anesthesia controllability is more and more strong, safety is more and more high, anesthesia is dominated when general anesthesia has become surgical operation therapy, guardian technique when tracheal intubation is again general anesthesia, need after tracheal intubation to use bite-block to fix airway, prevention patient stings pipe and catheter displacement, but the fixing rear stability of bite-block existence of present Clinical practice is not good enough, buccal dissociates the defects such as easy damaged oral mucosa.Therefore, be necessary that bite-block is improved, improve safety and effectiveness.

Summary of the invention

The purpose of this utility model proposes one exactly and avoids patient to sting flat airway, avoids pipe joint to slip into the Novel anesthesia dental pad of oral cavity gathering hole transmucosal, to solve the deficiencies in the prior art.

This Novel anesthesia dental pad that the utility model proposes, it is characterized in that it has an airway grooving, during application, airway is pressed into grooving internal fixtion, allows patients teeth sting on grooving, grooving has the gear ring gear preventing airway to be shifted, the gland seam of grooving runs through cell wall and gear ring gear.

Gland seam vertical masonry joint or curved slot.

Cell wall and the link of gear ring gear of grooving are integrated and make with harmless plastics.

Immobilization with adhesive tape is used between grooving and airway.

Gear ring gear is annulus or elliptical ring.

Gear ring gear is positioned at grooving middle and upper part.

This utility model uses like this: after patient's trachea intubate, determine airway position, airway is pressed in grooving, namely in bite-block, putting gear ring gear is positioned at outside lower teeth, bite-block and airway are properly fixed with adhesive tape, adhesive tape two ends are bonded on patient's facial skin, put or move about preventing airway.

This utility model has following features:

1, can conveniently effectively fix with airway;

2, bite-block is wrapped in airway outer end, and does not independently take oral cavity space, facilitates intraoral therapy and nursing.

3, bite-block far-end is not free in oral cavity, effectively can prevent oral mucosa lesion, risk of avoiding infection.

In Fig. 1-8, the label of each several part is as follows:

Detailed description of the invention

Existing airway also known as endotracheal tube, its as shown in Figure 1, it is made up of air duct fitting 1, airway 3, looped pipeline 4 and looped pipeline joint 2.Pipe joint is vesica piscis, the widest part and pipe joint equal diameters.Airway transparent plastic becomes arc, just meets the path shape of patient's mouth to lung qi tube passage.Be inserted into lung qi pipe from oral cavity the lower end of airway during use, pipe joint is connected with respirator, and after inserting oral cavity, patients teeth bites airway.It is flat that result is that airway is often snapped, and hinders ventilation, cause a hidden trouble to patients ' lives.Sometimes can dehisce because of patient again excessive, pipe joint enters oral cavity and ties up space and lesion ports transmucosal, makes airway insert deeply simultaneously, and quality is breathed in impact.

Applicant forms structure as shown in Figure 2 after adopting this utility model to transform.Bite-block 5 in figure is exactly one section has gland to stitch the duroplasts grooving of 7, and groove has one to keep off ring gear 8 with it.Gear ring gear is positioned at groove body middle and upper part, reserves upper end part groove body so that rubberized fabric adhere fixes facing on airway.During use, airway is pressed in bite-block, because bite-block has certain elasticity, after airway press-in, bite-block just restores to the original state and is surrounded, and the part sewed on outside port cavity at gland encloses part with fixing adhesive plaster 6(dotted line institute) tube wall of airway and bite-block be just fixed together by stickup.During intubate, bite-block both can not slide on airway, had propped up again the gmatjpdumamics of the upper lower teeth of patient, had avoided airway and be snapped flat.Because gear ring gear is large compared with mouth, be in again outside tooth, pipe joint would not enter oral cavity, does not tie up oral cavity space, turn avoid the damage to oral mucosa, is more conducive to intraoral daily nursing.

This illustration 3-6 is the projection plane view that gland seam is the structure different azimuth of the curved slot of an angle of 90 degrees of turning back, and the lower end of gland seam is that cell wall has certain restriction to airway, fit better effects if.Baffle ring shown in figure is annulus.But gear ring gear not necessarily annulus, elliptical ring also can play phase same-action.

When gland seam changes the vertical masonry joint shown in Fig. 7-8 into, when all the other structures are constant, airway can be pressed into more easily, and airway also can be limited in bite-block, and total effect is substantially the same.

NM each several part and label described above.

This Novel anesthesia dental pad of this utility model is tried out through applicant certain military hospital local, and airway never occurred and is snapped the phenomenon that flat and oral mucosa is damaged and occurs, medical personnel are reflected well.
