[0002] The oral cavity is a very important structure in the human body. With the continuous updating of medical equipment and the advancement of technology, the use of oral mirrors in major hospitals and clinics is becoming more and more widespread. As the most commonly used medical tool in the oral department, the oral mirror plays a vital role in various examinations and treatments in the oral department. It is mainly used to check the health of various surfaces of teeth in the oral cavity, helping doctors to find potential problems in time for effective treatment. When using a oral mirror, because the temperature of the mirror surface is much lower than that of the oral cavity, the hot air from the throat is easily condensed into water mist on the mirror surface, which brings inconvenience to observation. Summary of the invention

[0003] The present invention is intended to provide a medical mouth mirror to solve the problem that water mist is easily formed on the mirror surface during use of the current mouth mirror, which is not conducive to observation.

After the connection is completed, gas is filled into the air inlet pipe and the liquid suction pipe. A part of the gas enters the first cavity after entering the air inlet pipe, and then is discharged from the air outlet to clean the water mist on the mirror surface; at the same time, a part of the gas can be controlled to enter the exhaust pipe from the air inlet section of the liquid suction pipe, and the pressure at the connection point between the liquid suction section and the exhaust pipe is reduced through the Venturi effect. The liquid in the patient's mouth enters the liquid suction section of the liquid suction pipe under the action of the air pressure in the mouth, so as to clean the liquid in the patient's mouth, and at the same time, some hot air in the mouth is also discharged from the liquid suction section.

[0006] Advantages of this solution: The mirror and handle are designed to be split, which is convenient for running water cleaning and high-temperature disinfection, and the handle can be reused; a single device can achieve mirror water mist cleaning and liquid suction, which is convenient for operators to observe the patient's oral condition and use the equipment; airflow is used to synchronously achieve mirror water mist cleaning and liquid suction, saving resources; the exhaust pipe and handle form a handle structure, which is convenient for operators to use.

[0023] A medical mouth mirror, as shown in the following Figure 1 and attached Figure 2 As shown, it includes: a handle 1, a base 2 and a mirror 3, the base 2 and the handle 1 are connected in a detachable manner, specifically, the hand-held part and the mirror body can be designed to have magnetic materials, and the handle 1 and the base 2 are connected by magnetic adsorption, which is simple and easy to use. Alternatively, the handle 1 and the base 2 are installed by plug-in matching.

[0024] The mirror 3 is fixed on the base 2 , and a cavity is provided in the base 2 . The cavity is divided into a first cavity and a second cavity which are not connected to each other. The first cavity is located in the inner wall of the edge of the base 2 , and the second cavity is located between the base 2 and the mirror 3 .

[0025] In this embodiment, the base 2 and the handle 1 are connected through a connecting seat 6, one end of the connecting seat 6 is fixed on the base 2, and the other end of the connecting seat 6 is installed with the handle 1 by plugging. The mirror 3 and the handle 1 are designed to be split, which is convenient for running water cleaning and high-temperature disinfection, and the handle 1 can be reused. The connecting seat 6 is provided with a non-connected air inlet cavity and a liquid suction cavity, the air inlet cavity is connected to the first cavity, and the liquid suction cavity is connected to the second cavity.

[0026] An air outlet 7 and a liquid suction port 8 are provided at the edge of the base 2. The air outlet 7 is connected to the first cavity, and the liquid suction port 8 is connected to the second cavity. The air outlet 7 is located outside the mirror surface 3. In this embodiment, a plurality of air outlets 7 are provided. The air outlets 7 are evenly distributed in a ring shape on the side facing the mirror surface 3 to fully clean the mirror surface 3 and keep the image reflected by the mirror surface 3 clear. In this embodiment, there are two air outlets 7 at both ends of the mirror surface 3, forming an angle of 60°, and a liquid suction port 8 is provided at the edge of the mirror surface 3.

[0027] A first partition plate 9 is provided in the handle 1, and the first partition plate 9 divides the handle 1 into an incommunicating air inlet pipe 11 and a liquid suction pipe 12 along the axial direction of the handle 1. The handle 1 is used to form the air inlet pipe 11 and the liquid suction pipe 12, which has a simpler structure and lower cost.

[0028] The air inlet pipe 11 is connected to the cavity, the liquid suction pipe 12 is connected to the liquid suction port 8, the liquid suction pipe 12 is located in the cavity of the handle 1 and is provided with a second partition plate 4, the second partition plate 4 separates the liquid suction pipe 12 into an air inlet section and a liquid suction section that are not connected, and the liquid suction pipe 12 is located in the cavity of the handle 1. The side of the section is provided with an exhaust port, and the exhaust port is connected to the exhaust pipe 5. In this solution, the exhaust pipe 5 is used to form a handle structure with the handle 1, which is convenient for operators to use.

[0029] The second partition plate 4 is located within the cross-sectional range of the exhaust pipe 5. The second partition plate 4 divides the liquid pipette 12 into an air intake section and a liquid suction section respectively connected to the exhaust pipe 5. The length of the second partition plate 4 is greater than or equal to the diameter of the liquid pipette 12 to prevent the gas in the air intake section from being directly discharged into the liquid suction section, which affects the liquid suction effect. Gas is filled into the air intake pipe 11 and the liquid pipette 12. A part of the gas enters the first cavity after entering the air intake pipe 11, and then is discharged from the air outlet 7 to clean the water mist on the mirror surface 3; at the same time, a part of the gas enters the air intake section of the liquid pipette 12 and enters the exhaust pipe 5, thereby lowering the pressure at the connection between the liquid suction section and the exhaust pipe 5. The liquid in the patient's mouth enters the liquid suction section of the liquid pipette 12 under the action of the external air pressure, and the liquid in the patient's mouth is cleaned. At the same time, part of the gas in the mouth is discharged from the liquid suction section. A single device can clean the water mist on the mirror surface 3 and suck liquid, which is convenient for the operator to observe the patient's oral condition and for the operator to use the device.

[0030] The distance between the second partition plate 4 and the end of the exhaust pipe 5 close to the base 2 is greater than or equal to one quarter of the diameter of the exhaust pipe 5 , and less than or equal to one third of the diameter of the exhaust pipe 5 .

[0031] The air inlet cavity is connected to the air inlet pipe 11, and the liquid suction cavity is connected to the liquid suction pipe 12. The air inlet cavity and the liquid suction cavity are arranged on the base 2 to correspond to the corresponding cavities, so as to guide the gas in the air inlet pipe 11 into the first cavity, and then flow to the air outlet 7 to clean the mirror water mist; the liquid suction cavity drains the liquid in the corresponding second cavity into the liquid suction pipe 12.

[0032] The diameter of the liquid suction pipe 12 is smaller than the diameter of the exhaust pipe 5. The gas flow rate is further increased, the pressure at the connection point between the liquid suction section and the exhaust pipe 5 is reduced, and the liquid suction speed is accelerated.

[0033] The diameter of the exhaust pipe 5 gradually increases along the exhaust direction, further increasing the gas flow rate, reducing the pressure at the connection between the liquid suction section and the exhaust pipe 5, and accelerating the liquid suction speed. The position of the exhaust pipe 5 can be set according to the general habits of the operator to facilitate the operator to take the handle 1.

[0034] The specific implementation process is as follows: plug the connecting seat 6 and the handle 1, connect the air inlet cavity with the air inlet pipe 11, and connect the liquid suction cavity with the liquid suction pipe 12; then connect the handle 1 away from the mirror surface 3 with the corresponding inflation air intake device, so that the gas enters the air inlet pipe 11 and the liquid suction pipe 12, and a part of the gas enters the first cavity from the air inlet pipe 11, and then is discharged from the air outlet 7 to clean the water mist on the mirror surface 3; another part of the gas enters the exhaust pipe 5 from the air inlet section of the liquid suction pipe 12, reducing the pressure at the connection point between the liquid suction section and the exhaust pipe 5, so that the liquid and part of the gas in the patient's mouth enter the liquid suction section of the liquid suction pipe 12 from the liquid suction port 8 under the action of the external air pressure, thereby cleaning the liquid in the patient's mouth.

[0035] This solution can achieve water mist cleaning of the mirror surface 3 and suction of liquid in the patient's mouth through airflow, saving resources; water mist cleaning of the mirror surface 3 and suction of liquid in the patient's mouth can be achieved through a single device, the structure is simple, and the problem of needing two hands to take the liquid suction tube and the mouth mirror respectively in the traditional way is solved, which is convenient for operators to use; the mirror surface 3 and the handle 1 are designed to be split, which is convenient for running water cleaning and high-temperature disinfection, and the handle 1 can be reused; the exhaust pipe 5 and the handle 1 form a handle structure, which is convenient for operators to use.

Adjusting the relative angles of the two mirror surfaces 3 facilitates seeing the deep parts or special parts that cannot be observed in daily life in the limited intraoral space. In this embodiment, there are two air outlets 7 and two liquid suction ports 8, and the air outlets 7 and the liquid suction ports 8 are arranged relative to each other.
