Detailed description of the invention

Defer to technique scheme, as shown in Figures 1 to 4, this programme discloses a kind of oral cavity conduit retainers, including bite-block plate 4, bite-block plate 4 generally arcuate structure, bite-block plate 4 offers the through hole running through bite-block plate 4, the trailing flank 402 of bite-block plate 4 is provided with the airway 7 of the arc passing through company with through hole.

The agent structure of this programme includes a bite-block plate 4, the overall curved structure of bite-block plate 4, it is possible to regarding one section of structure cut down from pipe wall as, bite-block plate 4 width, span and thickness are uniform. The effect of bite-block plate 4 is, plays the effect installing airway 7, simultaneously facilitates and follow-up arranges the structure such as groove 2 and occludator 8. In use, bite-block plate 4 serves as a contrast inside external teeth, lip, and therefore its monnolithic case is arc, in order to fit with the surface arranging tooth up and down. As it is shown in figure 1, the equal leaving certain gaps uncovered by the economic plan 13 in the middle part of bite-block plate 4 top and bottom. Human gingiva and upper lip internal connection, there is a frenulum of upper lip in the front being positioned at cutting, and there is frenulum of lower lip in the front of lower cutting. When bite-block plate 4 liner is when leading flank, the upper end of bite-block plate 4 and gingiva top and joint, junction inside lip.In order to not make frenulum of upper lip be oppressed or damage, it is provided with breach 13, to play the effect of protection frenulum of upper lip and frenulum of lower lip.

In this programme, in order to provide unobstructed breathing environment for patient better, bite-block plate 4 is provided with airway 7. Airway 7 is hard body, and entirety is also arcuation, and this is in order to the matching form with tongue and throat closes; After airway 7 is arranged in patient's oral area, airway 7 is attached to tongue, and its rear end is positioned at patient throat, and oxygen can effectively import to the respiratory tract of patient. Owing to oral cavity space is limited, in conjunction with the actual physiological structure in oral cavity, the cross section of airway 7 is oval or fillet square, makes ventilation space bigger, it is easier to laminating lingual surface.

The bite-block plate 4 of this programme is made with soft material, for instance silica gel material, is therefore easily deformed. In order to make it in use, through hole is indeformable is lined with the reinforcing pipe 6 of hard in through-holes so that ventilation is more smooth and easy, and the front end of reinforcing pipe 6 is stretched out the leading flank 401 of bite-block plate 4 and is provided with collar 5, the rear end of reinforcing pipe 6 and described airway 7 company of passing through. Reinforcing pipe 6 is hard structure, even if under the effect of patient's occlusion, without deformation.

As depicted in figs. 1 and 2, bite-block plate 4 being provided with the fixed station 1 being raised in bite-block plate 4 leading flank 401, fixed station 1 offers the draw-in groove 3 for fixing tracheal intubation, draw-in groove 3 runs through bite-block plate 4.

When tracheal intubation is through bite-block plate 4, owing to tracheal intubation is hard structure, when itself and standing part contact surface are more big, its fixed effect is more good, being provided with fixed station 1 for this this programme at leading flank 401, fixed station 1 is the structure being raised in bite-block plate 4 surface, and fixed station 1 offers draw-in groove 3; Owing to being provided with fixed station 1, draw-in groove 3 is therefore made to have certain extended distance; When tracheal intubation extend into cavity interior by draw-in groove 3, there is bigger contact area between outer wall and draw-in groove 3 inwall of tracheal intubation, the bite-block plate 4 fixed effect to tracheal intubation can be strengthened.

More specifically, draw-in groove 3 be arranged two in parallel, the width of two draw-in grooves 3 is different; Between two draw-in grooves 3, the edge of one of them draw-in groove 3 and fixed station 1 connects each through groove 2.

Two draw-in grooves 3 are through, generally I-shaped. And draw-in groove 3 and outside are also through. Namely in use, tracheal intubation slides into draw-in groove 3 from bite-block plate 4 is outside by groove 2, selects a draw-in groove 3 to be fixed. The width of two draw-in grooves 3 is different, can coordinate the tracheal intubation of different tube diameters. Draw-in groove 3 wall and bite-block plate 4 are elastic construction, therefore under the effect of frictional force and elastic force, can tracheal intubation effectively be fixed.

In order to strengthen the fixed effect intubated as far as possible, the side of fixed station 1 offer clamping slot 11 around fixed station 1, clamping slot 11 be detachably provided with fixing bullet card 12. Fixing bullet card 12 is one section of elastic rod surrounded in round, and the two ends of fixing bullet card 12 are all bent to hook-type, and the two ends of fixing bullet card 12 can act in collusion fixing.

As shown in Figure 4, Figure 5, after intubating and setting through draw-in groove 3, fixing bullet card 12 is opened, it is looped around on clamping slot 11, then more fixing bullet card 12 is acted in collusion fixing, draw-in groove 3 inwall so can be made to be close to and intubate surface, effectively enhance fixed effect. For the ease of the use of fixing bullet card 12, it is additionally provided with bulb 10 at elastic rod two ends.

As the further improvement to technique scheme, in this programme, bite-block plate 4 being provided with the soft occludator 8 being raised in bite-block plate 4 trailing flank 402, described through hole runs through occludator 8; Be provided with soft connecting plate 9 in the side of occludator 8, described draw-in groove 3 runs through soft connecting plate 9.

As in figure 2 it is shown, as being not provided with occludator 8, after patient wears this holder, upper cutting, lower cutting are engaged on airway 7, airway 7 hard, it is easy to tooth is produced damage. Be provided with occludator 8 for this, occludator 8 is enclosed in airway 7 around, and it is soft silica gel structure. After such patient wears, upper and lower cutting is stung on occludator 8, does not directly contact with the airway 7 of hard, thus makes tooth obtain and be effectively protected. The structure of occludator 8 is as shown in Figure 3, from the figure, it can be seen that define occlusal crib 14 between the occludator 8 of this programme and the dorsal surface of bite-block plate 4, occlusal crib 14 has two, it is distributed in the top and the bottom of occludator 8, corresponds respectively to upper cutting part and the incision toothed portion of human body; The another one effect of occludator 8 is, due to the setting of occlusal crib 14, when, after dental articulation, can bite-block plate 4 and occludator 8 be stuck on tooth, thus ensureing the firm of whole holder, position not change in use. It addition, the upper and lower edge of occludator 8 all extends a part, wherein go up along extension longer. Up and down after extension, it is attached to respectively on maxillary and the lower jaw of patient, makes patient perceptions better, also make fixed effect better simultaneously.
