Description

Technical Field

[0001] The present invention relates to the technical field of oral diagnosis and treatment devices, and in particular to a mouth mirror for oral examination based on oral restoration. Background Art

[0002] The oral cavity is the starting part of the digestive tract. It is connected to the outside world through the fissure in the front and is connected to the pharynx through the pharyngeal isthmus in the back. There are organs such as teeth and tongue in the oral cavity. The front wall of the oral cavity is the lip, the side wall is the cheek, the top is the palate, and the floor of the oral cavity is the mucosa and muscle structures. The oral cavity is divided into the oral vestibule in the anterior and lateral part and the proper oral cavity in the posterior and medial part by the upper and lower dental arches. There are many types of diseases in the oral cavity, such as periodontitis, oral ulcers, caries, etc. When diagnosing and treating different oral diseases, an oral mirror is usually required. The oral mirror can better observe the blind spots in the oral cavity and plays a positive role in diagnosis and treatment. However, in the prior art, when the oral mirror is placed in the patient's mouth, water mist will adhere to the oral reflector, affecting observation. In addition, when the liquid secreted in the mouth adheres to the oral reflector, it will further affect the observation of medical workers, thereby affecting the effect of diagnosis and treatment.

[0003] The Chinese invention patent with announcement number CN114916902B in the prior art discloses an intelligent oral auxiliary diagnosis and treatment device, which includes an operating handle, a ring plate is fixed at one end of the connecting rod away from the operating handle, a reflector is fixed inside the ring plate, and a first chamber and a conical bin are opened inside the operating handle. The grid heating plate heats the air inside the conical bin, and when the fan blade rotates, the heated gas inside the conical bin is blown to the inside of the air guide bin, and the heated gas flows to the inside of the second air guide tube through the air guide bin, and then blows to the surface of the reflector from the inside of the second air guide tube, preheating the reflector to avoid water mist due to temperature difference when the reflector is placed inside the oral cavity, and in addition, the preheated reflector is placed inside the oral cavity, when water droplets or saliva are attached to the reflector, the gas blows to the surface of the reflector after passing through the second air guide tube, and these water droplets or saliva will be discharged from the second support rod, so that the reflector remains clear, which is convenient for medical workers to observe the blind spots of the oral cavity.

[0004] The above-mentioned device can preheat the reflector and blow away the water drops or saliva attached to the reflector, so that the medical staff can observe the patient's oral cavity through the reflector. However, since the area of ​​the reflector that needs to be processed at the air outlet end of each second airway in the above-mentioned device is different, for example, the area of ​​the reflector that needs to be processed for the second airway at the center of the reflector is the largest, and the processing area of ​​other second airway tubes gradually decreases, and the second airway and the internal structure thereof are not processed in a targeted manner, which may affect the processing effect of the reflector. In the prior art, the medical staff will replace the reflector or clean the reflector after using it on a patient, but the cleaning of the above-mentioned device is difficult, which affects the use efficiency of the device. Summary of the invention

[0005] The embodiment of the present application solves the technical problems in the prior art that the processing effect of the reflector is affected and the cleaning of the reflector is difficult by providing a mouth mirror for oral examination based on oral restoration.

[0006] The embodiment of the present application provides a mouth mirror for oral examination based on oral restoration, comprising an operating rod, a connecting rod, an annular plate and a reflector, wherein one end of the connecting rod is detachably mounted on the operating rod, and the other end of the connecting rod is fixedly connected to the annular plate, the connecting rod can be bent, and an airway is provided in the connecting rod, an arc-shaped groove is provided in the annular plate, an air chamber is provided in the operating rod, an annular heating plate is installed at one end of the air chamber facing the connecting rod, the air chamber and the arc-shaped groove are connected to each other through the airway, the reflector is installed inside the annular plate, and the air outlet end of the arc-shaped groove faces the reflector A plurality of air outlets are provided on one side of the annular plate away from the connecting rod, and the annular plate also includes a plurality of ventilation pipes 1 and two ventilation pipes 2. The ventilation pipes 1 and 2 are all installed on the annular plate, and the plurality of ventilation pipes 1 are all located between the two ventilation pipes 2. The internal structures of the ventilation pipes 1 and 2 are the same; one end of the ventilation pipes 1 and 2 are connected with the arc groove, and the other end openings are all facing the reflector; two supports are installed in each of the ventilation pipes 1 and 2, an auger is rotatably installed between the two supports, and the length of the auger in the ventilation pipe 2 is greater than the length of the auger in the ventilation pipe 1.

[0007] Furthermore, an air intake pipe is installed at the end of the operating rod away from the connecting rod, the air intake pipe is connected to an air pump, and the air intake pipe is connected to the air chamber. A plug interface for plugging the connecting rod is coaxially opened at one end of the operating rod facing the connecting rod, and a connecting bag is fixedly installed on the periphery of the plug interface. The connecting bag can expand, and after the connecting bag expands to its maximum expansion degree, it can clamp and fix the connecting rod. A branch pipe is also fixed in the operating rod, one end of the branch pipe is connected to the connecting bag, and the other end of the branch pipe is connected to the air intake pipe. A pressure valve is also installed at the air outlet end of the air intake pipe. When the air pump inputs gas, the gas enters the connecting bag through the branch pipe after entering and expands the connecting bag. After the connecting bag expands to its maximum expansion amount, the continued input of gas will increase the air pressure in the air intake pipe. When the air pressure reaches a preset value, the pressure valve can be opened to input gas into the air chamber.

[0008] Furthermore, the radius of the auger in each of the ventilation pipes 1 gradually decreases along the airflow direction in the ventilation pipe 1.

[0009] Furthermore, the radius of the auger in each of the second ventilation pipes gradually increases along the air flow direction in the first ventilation pipe.

[0010] Furthermore, magnet 1 is installed at both front and rear ends of the blades of the auger in each ventilation pipe 1, magnet 2 is installed on the side where two supports in the ventilation pipe 1 are close to each other, magnet 1 and magnet 2 repel each other, and the auger can slide on the two supports.

[0011] Furthermore, the magnets installed at the front and rear ends of the auger are symmetrical with each other with the center line of the auger as the axis.

[0012] Furthermore, baffles for limiting the auger from leaving the support are installed at both ends of the shaft of each vent pipe, and a buffer bag is fixedly installed on one end of the baffle facing the support, and the buffer bag is an annular bag.

[0013] Furthermore, a rotating ring is rotatably mounted on one end of the support in each of the ventilation pipes toward the baffle, and the radius of the rotating ring is greater than the radius of the buffer bag.

[0014] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0015] First, the present invention lengthens the length of the auger in the second ventilation tube and reduces the length of the auger in the first ventilation tube, so that the gas can be blown in a targeted manner according to the needs of different areas, thereby improving the cleaning efficiency of the reflector, keeping the reflector clear, and allowing medical workers to observe the situation inside the oral cavity more accurately, thereby improving the accuracy and safety of diagnosis and treatment;

[0016] Secondly, the present invention provides a connection bag and a pressure valve, so that when installing the connection pipe, the connection bag can be expanded to clamp the connection pipe, and only when the connection bag is expanded and clamped tightly, the gas that continues to be input can enter the air pressure and complete the cleaning of the reflector, which not only simplifies the installation difficulty of the device, but also facilitates the cleaning of the reflector by medical staff, and ensures that the reflector is cleaned only when the connection pipe is firmly fixed, avoiding the occurrence of the reflector falling due to unstable connection, and increasing the comfort of medical staff;

[0017] Thirdly, the present invention reduces the torque on the auger and the rotational momentum by setting the auger in the ventilation pipe one to have a large radius at the air inlet end and a small radius at the air outlet end, so as to reduce the rotational speed of the gas when it leaves the auger. As the airflow passes through the auger, it gradually contracts and forms vortices at the end of the auger. These vortices effectively blow away the water droplets at the center of the reflector or blow them to the sides of the reflector, thereby maintaining a clear field of vision at the center of the reflector; by setting the auger in the ventilation pipe two to have a small radius at the air inlet end and a large radius at the air outlet end, the gas maintains a higher rotational speed when leaving the auger. As the airflow passes through the auger, it gradually diffuses and forms a more uniform airflow distribution after leaving the auger. These uniformly distributed airflows effectively blow the water droplets on both sides of the reflector away from the reflector, further ensuring a clear field of vision for medical staff;

[0018] Fourthly, the present invention increases the rotational momentum of the auger and improves the rotational efficiency of the auger by allowing the auger in the ventilation pipe to slide back and forth on the support, so that the gas in the ventilation pipe can reduce the energy consumption of driving the auger, and prolong the contact time with the reflector after the gas leaves the ventilation pipe, thereby blowing the water droplets or saliva appearing at the center of the reflector to both sides of the reflector, further maintaining the cleanliness of the center of the reflector, which is convenient for medical staff to observe.

DETAILED DESCRIPTION

[0028] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the drawings show preferred embodiments of the present invention, but the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosed content of the present invention.

[0029] It should be noted that the terms “vertical”, “horizontal”, “up”, “down”, “left”, “right” and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Embodiment 1: Figure 1-Figure 3As shown, the embodiment of the present application discloses a mouth mirror for oral examination based on oral restoration, comprising an operating rod 100, a connecting rod 120, an annular plate 130 and a reflector 140, one end of the connecting rod 120 is detachably mounted on the operating rod 100, and the other end of the connecting rod 120 is fixedly connected to the annular plate 130, and the connecting rod 120 can be bent. When medical staff conduct an oral examination on a patient, they first plug and install the sterilized connecting rod 120 and the reflector 140 on the operating rod 100, and then hold the operating rod 100 to conduct an oral examination;

[0032] An air passage 121 is provided in the connecting rod 120, an arc groove 131 is provided in the annular plate 130, an air chamber 110 is provided in the operating rod 100, an annular heating plate 111 is installed at one end of the air chamber 110 facing the connecting rod 120, the air chamber 110 and the arc groove 131 are connected to each other through the air passage 121, the reflector 140 is installed inside the annular plate 130, and the air outlet end of the arc groove 131 corresponds to the reflector 140. The annular plate 130 is provided with a plurality of air outlets 132 on one side away from the connecting rod 120, and further includes a plurality of ventilation pipes 1 200 and two ventilation pipes 210. The ventilation pipes 1 200 and the ventilation pipes 210 are both mounted on the annular plate 130, and the plurality of ventilation pipes 1 200 are both located between the two ventilation pipes 210. The ventilation pipes 1 200 and the ventilation pipes 210 have the same internal structure. One end of the ventilation pipes 1 200 and the ventilation pipes 2 210 is provided with a plurality of air outlets 132. It is connected to the arc groove 131, and the other end openings are all facing the reflector 140; each of the ventilation tube 1 200 and the ventilation tube 2 210 is equipped with two supports 220, and an auger 230 is rotatably installed between the two supports 220, and the length of the auger 230 in the ventilation tube 210 is greater than the length of the auger 230 in the ventilation tube 1 200. When performing an oral examination, the annular heating plate 111 is started, and the gas in the air chamber 110 is driven to enter the annular plate 130 through the connecting rod 120, and then discharged through the ventilation tube 1 200 and the ventilation tube 2 210. The heated gas can drive the auger 230 to rotate after passing through the auger 230. After the auger 230 rotates, the rotational momentum of the gas can be increased, and finally contact the reflector 140 in the annular plate 130, so that the reflector 140 can be defogged and the water droplets or saliva of the patient that may be attached to the reflector 140 can be blown away.

[0033] By lengthening the length of the auger 230 in the ventilation pipe 210 and reducing the length of the auger 230 in the ventilation pipe 200, the rotational momentum of the gas passing through the ventilation pipe 200 after passing through the auger 230 is smaller, which can extend the contact time between the gas and the reflector 140, thereby blowing the water drops or saliva appearing at the center position of the reflector 140 to the two sides of the reflector 140. When medical staff use the reflector 140, the center position of the reflector 140 is used most frequently. By setting the length of the auger 230 in the ventilation pipe 200, the cleanliness of the center position of the reflector 140 can be maintained first. The contact time between the gas passing through the ventilation pipe 210 and the auger 230 is long, so it can obtain more rotational momentum. The gas can be blown with a stronger rotational force, thereby blowing the water drops or saliva at the edge of the reflector 140 away from the reflector 140.

[0034] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0035] By lengthening the length of the auger 230 in the ventilation tube 210 and reducing the length of the auger 230 in the ventilation tube 1 200, the gas can be blown in a targeted manner according to the needs of different areas, thereby improving the cleaning efficiency of the reflector 140, keeping the reflector 140 clear, and allowing medical workers to observe the situation inside the oral cavity more accurately, thereby improving the accuracy and safety of diagnosis and treatment.

[0036] Embodiment 2: In order to solve the problem of cleaning and disinfecting the reflector 140 in the above embodiment, the connecting rod 120 and the operating rod 100 are improved to be detachable. However, since the connecting pipe also plays a role in gas circulation, in order to avoid the situation where the connecting rod 120 is separated from the operating rod 100 due to ventilation when the connection between the connecting rod 120 and the operating rod 100 is not firm, Figure 2 As shown, further improvements are made to the first embodiment:

[0037] Preferably, an air inlet pipe 150 is installed at one end of the operating rod 100 away from the connecting rod 120, and the air inlet pipe 150 is externally connected to an air pump (not shown in the figure), and the air inlet pipe 150 is communicated with the air chamber 110. An inserting port 112 for inserting the connecting rod 120 is coaxially opened at one end of the operating rod 100 facing the connecting rod 120, and a connecting capsule 160 is fixedly installed on the periphery of the inserting port 112. The connecting capsule 160 is an annular capsule, and the connecting capsule 160 can expand. After the connecting capsule 160 expands to its maximum expansion degree, it can clamp and fix the connecting rod 120. 00 is also fixed with a branch pipe 180, one end of the branch pipe 180 is connected to the connecting bag 160, and the other end of the branch pipe 180 is connected to the air inlet pipe 150. A pressure valve 170 is also installed at the air outlet end of the air inlet pipe 150. When the air pump inputs gas, the gas first enters the connecting bag 160 through the branch pipe 180 and expands the connecting bag 160. When the connecting bag 160 expands to its maximum expansion amount, the continued input of gas will increase the air pressure in the air inlet pipe 150. When the air pressure reaches the preset value, the pressure valve 170 can be opened to input gas into the air chamber 110.

[0038] During installation, the medical staff first plugs the connecting rod 120 into the plug port 112, and then starts the air pump. When the air pump inputs gas, the gas first enters the connecting bag 160 through the branch pipe 180 and expands the connecting bag 160. When the connecting bag 160 expands to its maximum expansion amount, the continued input of gas will increase the air pressure in the intake pipe 150. When the air pressure reaches the preset value, the pressure valve 170 can be opened to input gas into the air chamber 110. Then the gas passes through the air chamber 110 and is discharged from the ventilation pipe 1 200 and the ventilation pipe 2 210 to defog the reflector 140 and clean water droplets.

[0039] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0040] By setting the connecting bag 160 and the pressure valve 170, when installing the connecting tube, the expansion of the connecting bag 160 can clamp the connecting tube, and only when the connecting bag 160 is expanded and clamped tightly, the continued input of gas can enter the air pressure and complete the cleaning of the reflector 140. This not only simplifies the installation difficulty of the device, facilitates the cleaning of the reflector 140 by medical staff, but also ensures that the reflector 140 is cleaned only after the connecting tube is firmly fixed, avoiding the reflector 140 falling off due to unstable connection, and increasing the comfort of use for medical staff.

[0041] Embodiment 3: In order to improve the cleaning effect of water droplets or saliva attached to the reflector 140, as shown in FIG. Figure 4-Figure 6 As shown, further improvements are made to the second embodiment:

[0042] Preferably, the radius of the auger 230 in each of the vent pipes 200 gradually decreases along the airflow direction in the vent pipe 200; the design of a large radius at the air inlet end and a small radius at the air outlet end is adopted, when the gas flows through the auger 230, the larger radius end first contacts the airflow, and due to the larger radius, the cross-sectional area of ​​the airflow passing through is also correspondingly increased, resulting in a slower airflow speed. The torque on the auger 230 is reduced, the rotational momentum is reduced, and the rotational speed of the gas when leaving the auger 230 is reduced. As the airflow passes through the auger 230, it gradually shrinks and forms vortices at the end of the auger 230. These vortices effectively blow away the water droplets at the center of the reflector 140 or blow them to the sides of the reflector 140, thereby maintaining a clear field of view at the center of the reflector 140.

[0043] Preferably, the radius of the auger 230 in each of the second vent pipes 210 gradually increases along the airflow direction in the vent pipe 1 200; the design of a small radius at the air inlet end and a large radius at the air outlet end is adopted. When the airflow passes through the auger 230, the smaller radius end contacts the airflow first. Due to the smaller radius, the cross-sectional area when the airflow passes through is also correspondingly reduced, resulting in faster airflow speed. According to the Bernoulli principle, the increase in flow rate leads to a decrease in static pressure, thereby generating greater power to drive the auger 230 to rotate, increasing the torque and rotational momentum of the auger 230, so that the gas maintains a higher rotational speed when leaving the auger 230. As the airflow passes through the auger 230, it gradually diffuses and forms a more uniform airflow distribution after leaving the auger 230. These uniformly distributed airflows effectively blow the water droplets on both sides of the reflector 140 away from the reflector 140, further ensuring a clear view for medical staff.

[0044] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0045] By setting the auger 230 in the ventilation pipe 1 200 to have a large radius at the air inlet end and a small radius at the air outlet end, the torque on the auger 230 is reduced, the rotational momentum is reduced, and the rotational speed of the gas when leaving the auger 230 is reduced. As the airflow passes through the auger 230, it gradually shrinks and forms vortices at the end of the auger 230. These vortices effectively blow away the water droplets at the center of the reflector 140 or blow them to the sides of the reflector 140, thereby maintaining a clear view of the center of the reflector 140; by setting the auger 230 in the ventilation pipe 2 210 to have a small radius at the air inlet end and a large radius at the air outlet end, the gas maintains a higher rotational speed when leaving the auger 230. As the airflow passes through the auger 230, it gradually diffuses and forms a more uniform airflow distribution after leaving the auger 230. These uniformly distributed airflows effectively blow the water droplets on both sides of the reflector 140 away from the reflector 140, further ensuring a clear view of the medical staff.

[0046] Embodiment 4: In order to further increase the flow path of the gas flowing through the ventilation pipe 200, so as to better clean the center position of the reflector 140, as shown in FIG. Figure 7-Figure 8 As shown, further improvements are made to the third embodiment:

[0047] Preferably, magnet 1 231 is installed at the front and rear ends of the blades of the auger 230 in each of the ventilation pipes 200, and magnet 2 221 is installed on the side where the two supports 220 in the ventilation pipe 200 are close to each other, and magnet 1 231 and magnet 2 221 repel each other, and the auger 230 can slide on the two supports 220.

[0048] Preferably, the magnets 231 installed at the front and rear ends of the auger 230 are symmetrical with each other with the center line of the auger 230 as the axis.

[0049] When the gas passes through the auger 230 in the ventilation pipe 200, the gas drives the auger 230 to rotate. During the rotation of the auger 230, the two sections of the magnet 1 231 will alternately generate magnetic repulsion with the magnet 2 221, thereby driving the auger 230 to slide back and forth on the support 220, thereby increasing the rotational momentum of the auger 230 and improving the rotational energy efficiency of the auger 230, so that the gas in the ventilation pipe 200 can reduce the energy consumption of driving the auger 230, and extend the contact time with the reflector 140 after leaving the ventilation pipe 200, thereby blowing the water droplets or saliva appearing at the center of the reflector 140 to the two sides of the reflector 140, thereby maintaining the cleanliness of the center of the reflector 140, which is convenient for medical staff to observe.

[0050] Preferably, baffles 232 for limiting the auger 230 from leaving the support 220 are installed at both ends of the axis of the auger 230 in each of the ventilation pipes 200, and a buffer bag 233 is fixedly installed at one end of the baffle 232 facing the support 220, and the buffer bag 233 is an annular bag.

[0051] Preferably, a rotating ring 222 is rotatably mounted on one end of the support 220 in each of the vent pipes 200 facing the baffle 232 , and the radius of the rotating ring 222 is greater than the radius of the buffer bag 233 .

[0052] The restriction by the baffle 232 and the buffer capsule 233 not only avoids excessive movement of the auger 230, which causes the blades of the rotating auger 230 to contact with the support 220, causing the auger 230 to lose rotational momentum or the rotating auger 230 to hit the support 220 and cause damage to the device, but also absorbs the vibration generated when the auger 230 moves, thereby avoiding the vibration of the reflector 140 during use, thereby improving the comfort of use for medical staff; the setting of the rotating ring 222 can enable the rotating ring 222 to rotate along with the buffer capsule 233 when the auger 230 moves to the buffer capsule 233 and contacts the rotating ring 222, thereby further reducing the loss of rotational momentum of the auger 230.

[0053] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0054] The auger 230 in the ventilation pipe 200 slides back and forth on the support 220, thereby increasing the rotational momentum of the auger 230 and improving the rotational energy efficiency of the auger 230, so that the gas in the ventilation pipe 200 can reduce the energy consumption of driving the auger 230, and prolong the contact time with the reflector 140 after leaving the ventilation pipe 200, thereby blowing the water droplets or saliva appearing at the center of the reflector 140 to the two sides of the reflector 140, thereby maintaining the cleanliness of the center of the reflector 140 and facilitating observation by medical staff.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
