Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an oral protective mask. Background Art

[0002] The oral infection treatment protective mask is a device specially used to protect the patient's face during dental treatment. It is usually made of durable and lightweight materials to cover the patient's face to prevent water, medicine, blood or other substances from splashing onto the face or eyes during treatment. Its significance lies in that it can not only effectively protect the patient's eyes and facial skin from infection sources or harmful substances, but also reduce discomfort during treatment and improve the safety and comfort of treatment. By using a protective mask, doctors can focus more on treatment, and patients can also feel a higher degree of security.

[0003] For example, a Chinese utility model patent (CN218418527U) discloses a protective mask for patients in the dental department, which states: "By providing an opening on the mask body, the mask can be used during the process of oral diagnosis and treatment of the patient, thereby protecting the patient's face and preventing saliva or medicine from splashing onto the patient's face, thereby protecting the patient's face. The utility model adopts a disposable connecting block, which improves safety performance and avoids disease transmission between patients. The block can also protect the patient's oral part and prevent saliva from flowing onto the mask to cause disease transmission." It also states: "Since the above-mentioned mask is not provided with a corresponding opening (the dental department needs the patient to keep the mouth open during diagnosis and treatment, and the doctor or nursing staff needs to hold medical equipment to detect or treat the patient's mouth), that is, the use of the above-mentioned mask will affect the normal diagnosis and treatment process of the oral cavity. Therefore, in the actual diagnosis or treatment process of the dental department, the patient's face is only shielded and protected by simple barriers such as disinfected towels, and the protection effect is poor." Technical problems.

[0004] To sum up the above, it can be known that the prior art utilizes an opening to be set on the mask body so that the mask can be used during the patient's oral diagnosis and treatment. However, this method has the following technical problems: However, the device only sets an opening of a fixed size on the mask, while in actual conditions, the sizes of the oral cavity of different patients are different, and according to the specific treatment situation, the degree of opening of the patient's mouth is also required to be different. The fixed-size opening cannot meet the actual use requirements. For this reason, the present application proposes an oral protection mask to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the invention

After the mask body is worn on the patient's face by binding ropes, the first support half ring and the second support half ring are inserted into the patient's mouth at the same time. Then, according to actual needs, the first support half ring and the second support half ring can be slid to both sides respectively to increase the distance between the first support half ring and the second support half ring. Then, the degree to which the patient's mouth is stretched can be determined according to the size of the patient's mouth to ensure the patient's comfort. The degree of stretching can also be adjusted according to the doctor's treatment needs, so that the doctor can clearly see the treatment area, so as to provide a better operating space and improve the treatment effect.

[0020] The oral protection mask provided by the present invention, after the mask body is worn on the patient's face by binding ropes, the first supporting half ring and the second supporting half ring are inserted into the patient's mouth at the same time, and then the first supporting half ring and the second supporting half ring can be slid to both sides respectively according to actual needs, so that the distance between the first supporting half ring and the second supporting half ring is increased, and then the degree to which the patient's mouth is stretched can be determined according to the size of the patient's mouth to ensure the patient's comfort, and the degree of stretching can also be adjusted according to the doctor's treatment needs, so that the doctor can clearly see the treatment area, so as to provide a better operating space, improve the treatment effect, so that the device can meet actual treatment needs, and improve the practicality of the device.

[0021] The oral protection mask provided by the present invention can rotate the handle when it is necessary to release the support for the patient's mouth, thereby causing the limiting claw to leave the limiting tooth plate, thereby releasing the restriction on the fixed relative position of the first supporting semi-ring and the second supporting semi-ring, and then the distance between the first supporting semi-ring and the second supporting semi-ring can be reduced under the pressure of the patient's facial muscles. In this process, the connecting rod slides toward the inside of the shell, causing the piston to squeeze the gas in the shell, resulting in a decrease in the volume of the air, an increase in pressure, and a reaction force, which reduces the speed at which the distance between the first supporting semi-ring and the second supporting semi-ring decreases, allowing the patient's oral and facial muscles to gradually adapt, avoiding discomfort or pain caused by sudden pressure changes, and improving the practicality of the device.

Moreover, through the design of the fixed net, the patient's breathing can be relatively smoother, thereby improving the practicability of the device.

[0023] The oral protection mask provided by the present invention can shield the eyes of the patient who wears it by attaching the protective lens to the outside of the mask body, thereby protecting the patient's eyes from being harmed by the strong light used in the treatment process, and the device can release the restriction between the plug block and the fixed block through two threaded rods, and then the plug block, the threaded rod, the connecting shaft, the protective lens, the second torsion spring, the limiting ring, the limiting groove, the block, the connecting ring and the third spring can be disassembled. Since this part of the structure does not directly contact the patient, it can be reused after cleaning and disinfection, thereby reducing the treatment cost, and the protective lens can be moved to drive the connecting shaft to rotate, thereby opening the protective lens, so that the doctor can observe the anesthesia situation through the patient's eyes to meet the actual treatment needs of cavity infection, and the restriction on the protective lens can be released by pulling the block, so that the protective lens can be attached to the mask body under the action of the elastic force of the second torsion spring to protect the patient's eyes. When it is necessary to check the patient's eye condition, there is no need to disassemble the entire device or the entire shielding mechanism, thereby reducing the probability of cross infection.

[0042] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0043] Embodiment 1:

[0044] Please refer to Figure 2-Figure 6 , an oral protection mask, comprising:

[0045] The support assembly includes a first support semi-ring 8 and a second support semi-ring 9, which are both slidably connected to the bottom of the first support plate 7, and are both slidably connected to the top of the second support plate 10.

The outer wall of the first support semi-ring 8 is fixedly connected with a sliding plate 12, and the sliding plate 12 is slidably connected to the inner wall of the second support semi-ring 9. The connecting rod 19 slides inside the second support semi-ring 9, which can improve the stability of the mutual sliding of the first support semi-ring 8 and the second support semi-ring 9.

[0046] The limiting component includes a limiting tooth plate 13, the outer wall of the second supporting semi-ring 9 is fixedly connected with the limiting tooth plate 13, the limiting tooth plate 13 is slidably connected to the inner wall of the first supporting semi-ring 8, the inner wall of the first supporting semi-ring 8 is rotatably connected with a rotating shaft 14, the outer wall of the rotating shaft 14 is fixedly connected with a limiting claw 15 adapted to the limiting tooth plate 13, the outside of the rotating shaft 14 and the upper and lower sides of the limiting claw 15 are respectively sleeved with a first torsion spring 16, in the absence of other external forces, the limiting claw 15 fits on the outside of the limiting tooth plate 13, limiting the first supporting semi-ring 8 and the second supporting semi-ring 9 from approaching each other, and does not limit the first supporting semi-ring 8 and the second supporting semi-ring 9 from moving away from each other, the two ends of the first torsion spring 16 are respectively fixedly connected to the outer wall of the limiting claw 15 and the inner wall of the first supporting semi-ring 8, and the top of the rotating shaft 14 is fixedly connected with a handle 17.

[0047] The buffer assembly includes a casing 18, the inner wall of the first supporting semi-ring 8 is fixedly connected to the casing 18, the inner wall of the casing 18 is slidably connected to a connecting rod 19, one end of the connecting rod 19 located outside the casing 18 is fixedly connected to the outer wall of the limiting tooth plate 13, one end of the connecting rod 19 located inside the casing 18 is fixedly connected to a piston 20, the piston 20 is slidably connected to the inner wall of the casing 18, the side of the piston 20 away from the connecting rod 19 is fixedly connected to a first spring 21, the end of the first spring 21 away from the piston 20 is fixedly connected to the inner wall of the casing 18, and the outer wall of the casing 18 is provided with two Through hole 22, after supporting the patient's mouth for a period of time, when the restriction between the first supporting half ring 8 and the second supporting half ring 9 is released, the first supporting half ring 8 and the second supporting half ring 9 approach each other, so that the piston 20 moves toward the inside of the sleeve 18, so that the piston 20 squeezes the gas in the sleeve 18, causing the volume of the air to decrease, the pressure to increase, and a reaction force to generate a slow speed of reducing the distance between the first supporting half ring 8 and the second supporting half ring 9, so that the patient's oral and facial muscles gradually adapt to avoid discomfort or pain caused by sudden pressure changes.

[0048] The towing assembly includes a sliding column 23 and a top plate 26. The inner wall of the second support plate 10 and near the four corners are slidably connected with the sliding columns 23. The tops of the four sliding columns 23 are fixedly connected with limiting plates 24. The top of the top plate 26 is fixedly connected to the bottom ends of the four sliding columns 23. The outside of the four sliding columns 23 is provided with a second spring 25. The two ends of the second spring 25 are fixedly connected to the limiting plate 24 and the outer wall of the second support plate 10. The top plate 26 can lift the patient's chin to improve the stability and comfort of the patient's wearing.

[0049] With the above structural design, after the mask body 1 is worn on the patient's face through the binding rope 3, the first supporting half ring 8 and the second supporting half ring 9 are inserted into the patient's mouth at the same time, and then the first supporting half ring 8 and the second supporting half ring 9 can be slid to both sides according to actual needs, so that the distance between the first supporting half ring 8 and the second supporting half ring 9 is increased. In this process, the sliding plate 12 slides inside the second supporting half ring 9, and the tooth plate 13 is restricted to slide inside the first supporting half ring 8. After the distance between the first supporting half ring 8 and the second supporting half ring 9 is adjusted to a suitable position, the distance between the first supporting half ring 8 and the second supporting half ring 9 is fixed under the restriction of the limiting claw 15, and the medical staff can release their hands. When it is necessary to release the support for the patient's mouth, the handle 17 can be turned, thereby causing the first torsion spring 16 to deform. The limiting claw 15 leaves the limiting tooth plate 13, thereby releasing the restriction on the fixed relative position of the first supporting half ring 8 and the second supporting half ring 9, and then the distance between the first supporting half ring 8 and the second supporting half ring 9 can be reduced under the pressure of the patient's facial muscles. In this process, the connecting rod 19 slides toward the inside of the shell 18, so that the piston 20 squeezes the gas in the shell 18, causing the volume of the air to decrease, the pressure to increase, and a reaction force to be generated, so that the speed of reducing the distance between the first supporting half ring 8 and the second supporting half ring 9 is reduced, so that the patient's oral cavity and facial muscles gradually adapt. When wearing the device, the patient's chin can be placed on the top plate 26. Through the arrangement of four second springs 25, the top of the top plate 26 can have a tendency to fit the bottom of the mask body 1, thereby providing support for the patient's chin position.

The fixed net 28 can block external fluff and reduce the situation where the patient's nose itches and causes sneezing, which affects the treatment.

[0052] Through the above structural design, the connection shell 27 can provide a space for the patient's nose to be placed, and the design of the fixed net 28 can facilitate the exchange of the patient's respiratory gas with the outside world.

[0053] Embodiment 3:

[0054] The oral protection mask provided in Example 1 is further optimized, specifically, as Figure 3-Figure 5As shown, the shielding mechanism 6 includes a fixed block 29, an insert block 30, a threaded rod 31, a protection component, and a pulling component. The outer wall of the mask body 1 is fixedly connected to two fixed blocks 29, and the inner walls of the two fixed blocks 29 are movably inserted with the insert blocks 30 respectively. The inner walls of the two fixed blocks 29 are respectively threadedly connected with threaded rods 31, and the threaded rods 31 are movably inserted in the insert blocks 30. The threaded rods 31 are provided with anti-slip disks for facilitating the rotation of the threaded rods 31. By rotating the threaded rods 31, the restrictions between the insert blocks 30 and the fixed blocks 29 can be released.

[0055] The protection component includes a connecting shaft 32, which is rotatably connected to the inner walls of the two plug-in blocks 30. The outer wall of the connecting shaft 32 is fixedly connected to a protective lens 33. The outer wall of the connecting shaft 32 and the two sides of the protective lens 33 are respectively sleeved with a second torsion spring 34. The second torsion spring 34 can make the protective lens 33 have a tendency to fit the outside of the mask body 1. The two ends of the second torsion spring 34 are respectively fixedly connected to the protective lens 33 and the outer wall of the plug-in block 30. The protective lens 33 is a dental protective glasses, which has a special filtering spectrum, can effectively reduce light stimulation to the eyes, and prevent ultraviolet rays or blue light from causing eye damage. Dental protective glasses are existing technology, so they will not be elaborated in detail.

[0056] The pulling assembly includes a limiting ring 35, an outer wall of the connecting shaft 32 and a limiting ring 35 is fixedly connected to one of the plug blocks 30, a plurality of limiting grooves 36 are provided on the outside of the limiting ring 35, a stopper 37 is slidably connected to the inner wall of an plug block 30 close to the limiting ring 35, a connecting ring 38 is fixedly connected to the outer wall of the stopper 37, a rounded corner is provided on one side of the bottom of the stopper 37 away from the side of the mask body 1, and the other side of the bottom is a right angle, thereby limiting the rotation of the limiting ring 35, when the limiting ring 35 rotates and causes the limiting groove 36 to squeeze the rounded corner, the stopper 37 slides upward, thereby not limiting the rotation of the limiting ring 35 in this direction, when the limiting ring 35 rotates and causes the limiting groove 36 to squeeze the right-angle side of the stopper 37, the stopper 37 cannot be squeezed upward, so that the limiting ring 35 cannot rotate, and a third spring 39 is sleeved on the outside of the stopper 37, and the two ends of the third spring 39 are respectively fixedly connected to the inner wall of the plug block 30 and the outer wall of the connecting ring 38.

[0057] With the above structural design, when the plug block 30 and related components are installed on the fixed block 29, the two plug blocks 30 are inserted into the corresponding positions on the corresponding fixed blocks 29, and then the two threaded rods 31 are rotated so that the two threaded rods 31 are respectively inserted into the corresponding plug blocks 30, so as to restrict the plug block 30 and the fixed block 29, and then the plug block 30, threaded rod 31, connecting shaft 32, protective lens 33, second torsion spring 34, limiting ring 35, limiting groove 36, block 37, connecting ring 38 and third spring 39 can be installed. When it is necessary to observe the patient's eye condition, the protective lens 33 can be moved to drive the connecting shaft 32 to rotate. In this process, the second torsion spring 34 is deformed, and the limiting ring 35 squeezes the rounded position of the block 37, forcing the block 37 to slide upward in the plug block 30, thereby making The third spring 39 is deformed, and as the limiting ring 35 rotates, the bottom of the block 37 leaves the limiting groove 36 and contacts the outer wall of the limiting ring 35. As the limiting ring 35 rotates further, the bottom of the block 37 corresponds to the top of the next limiting groove 36. Then, under the action of the elastic force of the third spring 39, the block 37 is inserted into the limiting groove 36, and the protective lens 33 is continuously rotated so that the protective lens 33 is opened until it does not hinder the doctor from observing the patient's eye condition. After the observation of the patient's eye condition is completed, the protective lens 33 can be attached to the mask body 1. The third spring 39 can be deformed by pulling the block 37, so that the block 37 leaves the corresponding limiting groove 36, and the restriction on the protective lens 33 is released, so that the protective lens 33 can be attached to the mask body 1 under the action of the elastic force of the second torsion spring 34.
