Description

A multi-functional oral saliva suction device

technical field

The utility model relates to a multifunctional oral saliva suction device. Suitable for dental medical devices. the

Background technique

Since dental medicine, during treatment, the saliva secreted by the patient affects the operator's vision and has become a major factor hindering the progress of stomatology.

At present, conventional saliva aspirators only have the function of absorbing liquid, and do not have the function of blocking soft tissues such as the tongue. Some saliva aspirators made of harder materials are easy to damage oral soft tissues due to the small area of the suction head. Especially in the operation of the cervical area of the teeth and the distal adjacent surface area, it is often necessary to pull the buccal and tongue body, observe the condition of the tooth body and at the same time need to absorb liquid, even if the assistant assists the operation, it is impossible It is easy for the operator to place many instruments in the patient's mouth. If the position of the conventional saliva suction device is not reasonable, it is easy to cause nausea and other discomfort reactions in the patient. Moreover, the conventional saliva suction device has no fixed device, and an assistant is often needed to assist in controlling the effective suction of saliva. and cooling water. Even so, it is often impossible to provide the operator with a clear view. For example, the patient's tongue and buccal soft tissues are often accidentally injured during the preparation of the posterior teeth.

Commonly used adapters are threaded plugs, which take a lot of treatment time to screw in during operation, and threaded plugs generally have high requirements for materials, such as metal, but the saliva suction device is easy to corrode metal adapters, and the conventional The production process of the adapter is cumbersome and demanding. Due to the instability of the thread, the number of uses is limited.

Contents of the invention

The technical problem to be solved by the utility model is to provide a multi-functional oral saliva suction device with simple operation, safe use and low cost in view of the above-mentioned problems, which can block the tongue, etc. while sucking saliva and cooling water. Oral soft tissue provides the operator with a clear view of the operation.

The technical scheme adopted in the utility model is: a multi-functional oral saliva suction device. On the device, the saliva suction tube is a plastic hollow hose with a metal wire inside, bent into an Ω shape as a whole, and the saliva suction tube is divided into a blocking section, a fixed section and an extension section, wherein the blocking section is formed into an elliptical disk, and There is a saliva suction hole at the lowest part of the elliptical disk; the fixed section is bent according to the shape of human lips and mandible; the extension section is connected with a universal adapter.

The universal adapter is a shuttle-shaped hollow hard rubber tube, which is wrapped outside the extension of the saliva suction tube and inserted into the saliva suction device. With the help of the specific shape of the adapter, it can be inserted into any dental treatment Various weak or strong suction devices for chairs.

The extension section is 10cm long, and there is no metal wire within the range of 3cm at the end, and the extension section is inserted into 1/3 of the universal adapter.

The beneficial effects of the utility model are: when the utility model is operated in the oral cavity, the blocking section can effectively block the tongue body; the saliva suction hole at the bottom can timely remove the saliva secreted from the mouth of the salivary gland duct, providing the operator with a clear vision ;The fixed section outside the mouth can fix the saliva suction tube at the patient's comfortable position without the help of an assistant, so it is easy to use; because the material of the saliva suction tube and the internal wire have plastic memory, the doctor can adjust it according to each patient's own According to the situation, the shape of the saliva suction tube is adjusted, the operation time is short, and the number of instruments in the patient's oral cavity is reduced, the patient's discomfort is relieved, and the doctor's treatment operation is convenient.

The utility model has the advantages of simple structure, ingenious design and convenient use. The universal adapter utilizes taper and frictional force to perform the connecting function, and saves clinical working time without rotating joints. The end of the dental chair can be applied to any caliber of saliva suction device, which increases the clinical utilization rate. Compared with other materials, the rubber material not only reduces the cost and prolongs the service life, but also its sealing effect is the best among all materials. the

Detailed ways

As shown in Figure 1, the present embodiment is a multi-functional oral saliva suction device, which is composed of a saliva suction tube 1 and a universal adapter 2, and the saliva suction tube 1 is inserted into the oral cavity through the universal adapter 2. In the saliva suction device 3 on the chair.

As shown in Figure 2, the saliva suction tube 1 in this example is made of a plastic hollow hose with a metal wire inside (it is made of the same material as the plastic parts of other disposable plastic products in the oral cavity, such as mouth mirrors, probes, etc.) , which is Ω-shaped as a whole. The saliva suction tube 1 is divided into three sections: a blocking section 11, a fixed section 12 and an extending section 13. The blocking section 11 is formed into an elliptical disk, which is used to block soft tissues such as the tongue, and can be adjusted according to the patient's oral condition. There is a saliva suction hole 14 on the top; the shape of the fixed section 12 is designed to be the shape of the lip and the mandible. The shape is designed according to the investigation of the Asian mandible recorded in relevant literature. In clinical use, the doctor makes minor adjustments according to the specific conditions of the patient. , which plays a fixed role at the lower turning of the mandible, and extends to the extension section 13; the extension section 13 is 10cm long, and there is no wire inside at the lower end 3cm, and it relies on the roughness of the plastic exterior to connect to the universal adapter 2 at the lower end .

As shown in Figure 3 and Figure 4, the universal adapter 2 is a shuttle-shaped hollow hard rubber tube (reusable after high-temperature and high-pressure sterilization), with a length of 10 cm. The inner diameter of the universal adapter 2 is slightly larger than the outer diameter of the saliva-absorbing tube 1, and the saliva-absorbing tube 1 is inserted in the inner 1/3 of the universal adapter 2, and is connected by friction and the elasticity of the rubber. The universal adapter 2 is inserted into the saliva suction device 3 on the dental chair. The outer diameter of the end of the adapter is smaller than that of all existing dental chair saliva suction devices. The device 3 is connected, and the application range is wide without limitation.

The working principle of this embodiment is as follows:

Put the blocking section 11 of the multifunctional saliva suction device in the oral cavity. The long axis of the elliptical disk is parallel to the dentition. Due to the protective effect of the elliptical disc, the rough opening at the end will not damage the soft tissue in the oral cavity, and the uppermost end of the saliva suction tube does not exceed the plane of the dentition, which will not affect clinical operations. The fixed section 12 starts from the lip, which is designed in the shape of the lip and extends to the turning point of the chin of the mandible. The saliva suction tube is fixed by the lip and chin. Since this material has plastic memory, it can be adjusted according to the patient's individual condition. Adjustable, easy to use, saves time. The extension section 13 is connected to the universal adapter 2, and there is no wire part inside the proximal end 3cm, which is convenient for connection.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art, within the scope of the present utility model, make changes, additions or replacements, which should belong to Protection scope of the present utility model. the
