Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 6, the medical bite-block comprises a bite-block body 1 and bite-block ears 2, the bite-block body 1 is of a hollow structure, the bite-block ears 2 are connected with the bite-block body 1, the medical bite-block further comprises a suction tube 3 and a negative pressure joint 4, a first suction hole 11 is formed in the bottom surface of the bite-block body 1, the suction tube 3 is inserted into the bite-block body 1, the bottom surface of the suction tube 3 is a plane and is connected with the bite-block body 1, a second suction hole 31 corresponding to the first suction hole 11 is formed in the bottom surface of the suction tube 3, and the negative pressure joint 4 is located outside the bite-block body 1 and is connected with the suction tube 3.

Bite block main part 1 is inserted into the oral cavity, and the bottom surface of bite block main part 11 is downward, when inhaling the saliva, is connected aspirator and negative pressure joint 4 with the connecting pipe, starts the negative pressure aspirator, and the suction effect of negative pressure can make saliva and the sputum that enters the oral cavity follow first suction hole 11 and second suction hole 31 and get into suction tube 3 and by the suction. Therefore, the utility model discloses have the saliva effect of inhaling, reducible quantity of inhaling the salivary duct reduces patient's burden.

Further, the utility model discloses preferentially attract pipe 3 and set up along 1 length direction of bite-block main part, attract the quantity of pipe 3 to be two, two attract pipe 3 intervals to set up, and the quantity of negative pressure joint 4 is one, and two attract pipe 3 all are connected with negative pressure joint 4. Thus, the number and the action range of the first suction holes 11 and the second suction holes 31 can be increased, and saliva in the oral cavity can be sucked completely.

The cushion ear 2 is in contact with the front surface of the patient's lips or teeth, and for the comfort of the patient, it is preferable that the cushion ear 2 includes a hard inner layer 21 and a flexible surface layer 22 attached to the hard inner layer 21. The flexible surface layer 22 may provide a pressure relief function that may improve patient comfort to some extent.

The patient in restlessness often pushes up the bite-block with the tongue outward, and although the bite-block is often fixed on patient's head with the frenulum, the outer top of frequent vigorous force easily leads to the bite-block slope to probably lose the effect of supporting the tooth, so patient's probably bite closed trachea cannula, very dangerous. At present, hospitals often adopt a mode of respectively arranging a tooth pad at two sides of a tracheal cannula to improve the reliability of supporting teeth, so that the using amount of the tooth pad is increased, and the oral cavity of a patient is fully filled. Therefore, the utility model discloses preferred medical bite-block is including preventing stinging frame 5, and the shape of preventing stinging frame 5 is the U-shaped, prevents stinging frame 5 and is located bite-block main part 1 one side, prevents stinging the open end of frame 5 and can dismantle with bite-block main part 1 and be connected, prevents that the upper and lower surface of stinging frame 5 all does not surpass bite-block main part 1.

When restless patient uses this bite-block, the installation is prevented stinging frame 5, prevents stinging frame 5 and entangles trachea cannula, even bite-block main part 1 is pushed up by patient's tongue and is inclined, prevents stinging frame 5 and still overlaps on trachea cannula, can play and prevent that trachea cannula from being stinged the effect of closing, improves the utility model discloses a reliability. The patient with clear-headed can be not provided with the anti-biting frame 5, so that the occupation of the oral cavity is reduced, and the comfort of the patient is improved to a certain degree.

The bite-preventing frame 5 is detachably connected to the bite-block main body 1 in a specific manner, preferably, as shown in fig. 6, two dovetail grooves 12 are provided on one side of the bite-block main body 1, and dovetail sliders 51 are provided at end portions of two side plates of the bite-preventing frame 5, and the dovetail sliders 51 are inserted into the dovetail grooves 12 and engaged with the dovetail grooves 12. The anti-biting frame 5 can be assembled and disassembled by inserting or withdrawing the dovetail slide block 51 into or from the dovetail groove 12.
