Description

Saliva suction occluder

Technical Field

The utility model belongs to the technical field of oral medical instrument, concretely relates to inhale saliva occluder.

Background

In oral treatment, masticatory muscle ache is often caused by overlong mouth opening time, the patient can involuntarily bite and fold to reduce the mouth opening, and the doctor can operate the visual field to be limited due to the undersized mouth opening, so that the oral treatment is influenced. And in oral treatment, need often use the saliva suction pipe to be used for extracting the saliva of patient's oral cavity, if the doctor often handheld saliva suction pipe absorb saliva, can influence oral treatment's progress, so generally need nurse station auxiliary operation on the side, it is comparatively loaded down with trivial details. To above-mentioned problem in clinical, often use the interlock pad to between the upper and lower dentition, support for the patient interlock provides, relieve and open a mouthful fatigue, provide sufficient and stable operation field of vision for the doctor, and set up the through-hole on the interlock pad, be used for passing the saliva suction tube, can play certain fixed action to the saliva suction tube, but discover in the in-service use, the fixed action of interlock pad saliva suction tube is relatively poor, the saliva suction tube passes the through-hole under self action of gravity and constantly slides in the patient oral cavity easily, thereby can influence doctor's operation.

Disclosure of Invention

The utility model discloses to the relatively poor drawback of interlock pad to the fixed action of inhaling the salivary duct among the prior art, provide an inhale saliva occluder, this inhale saliva occluder through set up the retaining ring on inhaling the salivary duct, can be used for control to inhale the depth that the salivary duct stretches into the patient oral cavity for supplementary fixed saliva duct of inhaling.

The invention aims to be realized by the following technical scheme: the utility model provides an inhale saliva occluder, includes that the interlock fills up and inhales the salivary duct, the interlock is filled up and is equipped with the through-hole that can not pass the through-hole and run through the interlock and fills up, it passes to inhale the salivary duct the through-hole just can slide along the through-hole, inhales the salivary duct and goes up the cover and be equipped with elastic retaining ring, retaining ring and inhale interference fit between the salivary duct. The retaining ring can be through can be comparatively firm fixing on inhaling the salivary duct under self elastic action, and the retaining ring can laminate on the interlock pad when inhaling in the salivary duct passes the through-hole, prevents to inhale the further oral cavity of sliding of salivary duct, plays one-way fixed effect to inhaling the salivary duct.

Preferably, the upper end surface and the lower end surface of the occlusion pad are respectively provided with an occlusion groove, and the occlusion grooves penetrate through the left end and the right end of the occlusion pad. The upper dentition and the lower dentition in the oral cavity of the patient can be respectively embedded into the occlusal groove, so that the occlusal pad can be bitten more firmly, and the occlusal pad is not easy to fall off.

Preferably, the biting pad is made of soft elastic materials, a supporting tube made of hard materials and positioned in the through hole is fixedly arranged on the biting pad, and the saliva suction tube penetrates through the supporting tube and can slide along the supporting tube. The occlusion pad made of soft elastic material is not easy to hurt teeth, and the supporting tube made of hard material can play a better supporting role and avoid the saliva suction tube passing through the supporting tube from being occluded to generate deformation.

Preferably, the two ends of the through hole on the occlusion pad are respectively provided with a groove, the inner diameter of each groove is larger than that of the through hole, two ends of the supporting tube are respectively fixedly provided with a limiting plate, the limiting plates protrude relative to the side surface of the supporting tube, and the two limiting plates are respectively embedded into the two grooves. The supporting tube arranged in this way can be more firmly arranged on the occlusion pad.

Preferably, the side of the limiting plate facing away from the supporting tube is flush with the outer side of the meshing pad.

Preferably, the bite pad is made of rubber.

Preferably, the upper side and the lower side of the supporting tube on the occlusion pad are provided with buffer holes penetrating through the occlusion pad. The patient bites on the occlusion pad, and the position of the occlusion pad provided with the buffer hole is easy to deform, so that the occlusion pad can play a little buffer effect and is not easy to hurt teeth.

Preferably, the side of the saliva suction pipe close to the saliva suction end is provided with a saliva suction port communicated with the inner cavity of the saliva suction pipe. Will inhale the side of saliva mouth setting at inhaling the saliva pipe, can avoid inhaling the saliva pipe and cause the damage to oral mucosa when absorbing the saliva, be favorable to protecting oral mucosa.

Preferably, the stop ring is made of rubber.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses simple structure, the interlock pad of setting can provide the supporting role for patient's interlock, alleviates a mouthful fatigue to for the doctor provides sufficient and stable operation field of vision, and the retaining ring that sets up can play one-way spacing effect to the salivary duct, avoids inhaling the salivary duct and too stretch into patient's oral cavity under self action of gravity, thereby plays supplementary fixed effect to the salivary duct.

Detailed Description

The invention will be further described with reference to the embodiments shown in the drawings to which:

example 1

As shown in fig. 1-5, an inhale saliva occluder, including occluding pad 1 and inhale salivary duct 2, occluding pad 1 adopts rubber to make, and occluding pad 1's cross section is isosceles trapezoid structure, and the narrower side sets up towards patient's oral cavity inboard on occluding pad 1, occluding pad 1's upper and lower terminal surface respectively is equipped with an occlusal groove 3, and occlusal groove 3 runs through occluding pad 1's left and right sides both ends, be equipped with between two occlusal grooves 3 on occluding pad 1 and run through occluding pad 1's through-hole 4, occluding pad 1 is last respectively be equipped with a recess 5 at through-hole 4's both ends, the internal diameter of recess 5 is greater than the internal diameter of through-hole 4. The occlusion pad 1 is fixedly provided with a supporting tube 6 made of a hard material and located in the through hole 4, two ends of the supporting tube 6 are respectively fixedly provided with a limiting plate 7 with an annular structure, the limiting plates 7 protrude out relative to the side face of the supporting tube 6, and the two limiting plates 7 are respectively embedded into the two grooves 5. The side surface of the limiting plate 7 back to the supporting tube 6 is flush with the outer side surface of the occlusion pad 1. The upper side and the lower side of the supporting tube 6 on the occlusion pad 1 are provided with buffer holes 8 which penetrate through the occlusion pad 1.
