Description

Technical Field

[0001] This application relates to the field of oral medical device technology, and in particular to a multifunctional oral mask. Background Technology

[0002] In dental treatments, the use of equipment such as high-speed handpieces and ultrasonic scalers generates a large number of droplets and aerosols containing pathogenic microorganisms. When preparing cavities with a high-speed handpiece, droplets can splash onto the dentist's forehead, face, and neck, with a splash rate of up to 42% from the jaw to the neck. Traditional masks only cover the mouth, nose, and forehead, leading to a higher incidence of mucosal contact infection due to neck exposure compared to the face. During complex procedures such as implant surgery and root canal treatment, patients frequently need to adjust their head position, making it easier for droplets to enter through gaps in the mask edges. This increases the risk of aerosol intrusion compared to routine procedures, directly leading to a significantly higher risk of respiratory infections for healthcare workers. Furthermore, light-cured resin restorations have become a mainstream technique in clinical dentistry. Long-term exposure to the 440-480nm blue light emitted by the curing lamp can cause cumulative damage to the eyes of healthcare workers. Therefore, healthcare workers must wear appropriate protective equipment according to regulations to effectively prevent eye damage and occupational exposure, and reduce the incidence of cross-infection.

[0003] However, in traditional dental hygiene protocols, face shields and blue light blocking glasses are separate components and must be worn separately. When procedures involve the use of light-curing lamps, healthcare professionals must remove the face shield before replacing it with blue light blocking glasses. Switching between different procedures requires repeated removal and donning of goggles and face shields, which is not only cumbersome and reduces treatment efficiency but also increases the risk of contamination due to frequent facial contact.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a multifunctional oral mask, which aims to solve the problems of cumbersome wearing, incomplete protection, and inconvenient switching operation of traditional protective equipment, so as to achieve simultaneous protection against droplets and blue light, improve the convenience of equipment use and the work efficiency of medical staff.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A multifunctional oral mask, comprising: The main frame body is used to fit over the user's head. The main frame body is equipped with integrated hinge mechanisms at the positions corresponding to the left and right temples of the human body. The integrated hinge mechanisms are movably connected to a first knob and a second knob, which are coaxially arranged. The first support frame has two ends connected to two first knobs respectively, so that the angle between the first support frame and the main frame body is adjustable. The first support frame is equipped with blue light blocking eye masks. And a second support frame, with two ends of the second support frame connected to two second knobs respectively, so that the angle between the second support frame and the main frame body is adjustable. A protective face shield is detachably connected to the second support frame, which is used to protect the user's face and neck. The first support frame and the second support frame are both arc-shaped support frames, and the main frame body, the first support frame and the second support frame are stacked in sequence.

[0007] In one possible implementation, the integrated articulated mechanism includes: A fixed base is fixed to the main frame body at the position corresponding to the human temple. A bushing is provided on the fixed base, and a central shaft hole is opened at the center of the bushing. A central rotating shaft passes through a central shaft hole and is fixedly connected to a first knob so that the first knob is rotatably connected to the central shaft hole. The two ends of the first support frame are respectively connected to two central rotating shafts so that the first support frame, the central rotating shaft and the first knob form a follower mechanism. The outer rotating shaft is sleeved on the bushing and is fixedly connected to the second knob so that the second knob rotates around the outer circumference of the central shaft. The two ends of the second support frame are respectively connected to the two outer rotating shafts so that the second support frame, the outer rotating shafts and the second knob form a follower mechanism.

[0008] In one possible implementation, a clearance is provided between the first support frame and the second support frame to allow the blue light blocking eye mask to pass.

[0009] In one possible implementation, the blue light blocking eye mask is detachably attached to the first support frame.

[0010] In one possible implementation, the blue light blocking eye mask has an avoidance notch at the position corresponding to the user's nose bridge, and the avoidance notch is used to avoid the user's nose bridge.

[0011] In one possible implementation, the main frame body is a ring-shaped frame, and a length adjustment device is provided on the ring-shaped frame to adjust the wearing diameter of the ring-shaped frame.

[0012] In one possible implementation, a plurality of snap-fit ​​components are provided on the outer side wall of the second support frame. The plurality of snap-fit ​​components are evenly arranged along the extension direction of the second support frame. A snap-fit ​​groove is provided on the protective face mask at the position corresponding to the snap-fit ​​component. The snap-fit ​​component and the snap-fit ​​groove are snapped together so that the protective face mask is snapped onto the second support frame.

[0013] In one possible implementation, the main frame body is a silicone frame.

[0014] In one possible implementation, at least one of the main frame body, the first support frame, and the second support frame is detachably connected to a lighting lamp.

[0015] Compared with the prior art, this application provides a multifunctional oral mask. When in use, the protective mask and the blue light blocking goggles can respectively block droplets and blue light emitted by the light curing lamp, avoiding respiratory infections caused by patient droplets and cumulative damage to the eyes caused by blue light. Medical staff can easily put up or put down the corresponding blue light blocking goggles or protective mask by turning the knob or moving the support frame (first support frame or second support frame), effectively improving the ease of use of the equipment and increasing the work efficiency of medical staff.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0023] This utility model provides, for example Figure 1 , Figure 2 , Figure 3The image shows a multifunctional oral mask used by medical personnel during oral treatments and light-cured resin restoration procedures to protect them from droplets and blue light emitted by the light-curing lamp, preventing respiratory infections caused by patient droplets and cumulative eye damage from blue light. The main structure includes a main frame body 1, a first support frame 2, and a second support frame 3. The main frame body 1 is fitted over the user's head, and integrated hinge mechanisms 4 are located on the main frame body 1 corresponding to the left and right temples. First knobs 41 and second knobs 42 are movably connected to the integrated hinge mechanisms 4, and are coaxially arranged. The two ends of the first support frame 2 are connected to the two first knobs 41 respectively. Rotating the first knobs 41 causes the first support frame 2 to move up and down, allowing the first support frame 2 to move in conjunction with the main frame body 1. The angle between the main frame 1 and the main frame 1 is adjustable. The first support frame 2 is equipped with a blue light blocking eye mask 21. The two ends of the second support frame 3 are respectively connected to two second knobs 42. When the second knobs 42 are rotated, the second support frame 3 can move up and down, so that the angle between the second support frame 3 and the main frame body 1 is adjustable. A protective face mask 31 is detachably connected to the second support frame 3. The protective face mask 31 is used to protect the user's face and neck. The first support frame 2 and the second support frame 3 are both arc-shaped support frames. The main frame body 1, the first support frame 2 and the second support frame 3 are stacked in sequence.

[0024] Understandably, when medical staff adjust the protective face shield 31 or the blue light blocking goggles 21, they can directly move the second support frame 3 or the first support frame 2. Alternatively, they can directly turn the second knob 42 and the first knob 41.

[0025] In use, this invention utilizes a protective face shield 31 and blue light blocking goggles 21 to protect against droplets and blue light emitted by a UV curing lamp, respectively. This prevents medical personnel from contracting respiratory infections from patient droplets and avoids cumulative eye damage from blue light. Medical staff can easily raise or lower the corresponding blue light blocking goggles 21 or protective face shield 31 by rotating a knob or using the support frames (first support frame 2 and second support frame 3), effectively improving the ease of use and work efficiency of medical personnel.

[0026] For example, when using a light-curing lamp, traditional operation requires first removing the protective face shield 31 and then putting on the blue light blocking goggles 21. After the light treatment, the blue light blocking goggles 21 must be removed and the protective face shield 31 must be put on again. The solution in this application allows for direct raising or lowering of the blue light blocking goggles 21 by turning the first knob 41 or moving the first support frame 2 according to clinical needs, eliminating the need for frequent removal and re-wearing. Furthermore, medical personnel can adjust the downward angle of the second support frame 3 according to their own head-down operating angle to achieve maximum protection for the face and neck.

[0027] Furthermore, such as Figure 3 , Figure 4As shown, the integrated hinge mechanism 4 includes: a fixed base 43, a central rotating shaft 44, and an outer rotating shaft 45. The fixed base 43 is fixed on the main frame body 1 at the position corresponding to the human temple. A bushing 431 is provided on the fixed base 43, and a central shaft hole 432 is opened at the center of the bushing 431. The central rotating shaft 44 passes through the central shaft hole 432 and is fixedly connected to the first knob 41 so that the first knob 41 is rotatably connected to the central shaft hole 432. The two ends of the first support frame 2 are respectively connected to the two central rotating shafts 44, so that the first support frame 2, the central rotating shaft 44, and the first knob 41 form a follower mechanism. The outer rotating shaft 45 is sleeved on the bushing 431 and is fixedly connected to the second knob 42 so that the second knob 42 rotates around the outer circumference of the central shaft. The two ends of the second support frame 3 are respectively connected to the two outer rotating shafts 45, so that the second support frame 3, the outer rotating shaft 45, and the second knob 42 form a follower mechanism.

[0028] It should be noted that, in order to prevent the first support frame 2 and the second support frame 3 from becoming loose and failing to maintain the set angle and position, in this embodiment, the central rotating shaft 44 and the central shaft hole 432 of the bushing 431 are connected by an interference fit; the outer rotating shaft 45 and the bushing 431 are also connected by an interference fit.

[0029] Of course, a gear shifting mechanism can also be provided between the central rotating shaft 44 and the bushing 431, and between the outer rotating shaft 45 and the bushing 431. This mechanism allows the knobs (first knob 41 and second knob 42) to remain at a preset gear angle during rotation. It also provides tactile feedback for the gear position. It is understood that the specific functions of the gear shifting mechanism in this embodiment are those that can be obtained by those skilled in the art based on existing technology; therefore, the structure and working principle of the gear shifting mechanism will not be elaborated upon here.

[0030] Furthermore, such as Figure 1 , Figure 2 As shown, a clearance 5 is provided between the first support frame 2 and the second support frame 3, and the clearance 5 is used to avoid the blue light blocking eye mask 21.

[0031] It should be noted that when medical staff rotate the first knob 41 to adjust the vertical position of the first support frame 2 and the blue light blocking eye mask 21, sufficient space is required for the first support frame 2 and the blue light blocking eye mask 21 to move up and down smoothly. Therefore, a clearance gap 5 needs to be set between the first support frame 2 and the second support frame 3 to allow the blue light blocking eye mask 21 to pass.

[0032] Furthermore, such as Figure 1 , Figure 2 and Figure 6As shown, a protective cover 51 is detachably connected to the first support frame 2. The protective cover 51 extends along the extension direction of the clearance gap 5 and is used to cover the clearance gap 5.

[0033] It should be noted that during oral treatment, droplets expelled from the patient's mouth may fall into the face of medical staff through the clearance gap 5 between the first support frame 2 and the second support frame 3. Therefore, in this embodiment, a protective cover 51 is provided on the first support frame 2 to cover the clearance gap 5, which can effectively prevent droplets expelled from the patient's mouth from falling into the face of medical staff through the clearance gap 5, thereby improving the protective effect of the mask.

[0034] Furthermore, the blue light blocking eye mask 21 is detachably connected to the first support frame 2. It is understood that the lifespan of the blue light blocking eye mask 21 will be shortened with prolonged and frequent use. Therefore, in this embodiment, the blue light blocking eye mask 21 is detachably connected to the first support frame 2, which facilitates medical personnel in replacing the blue light blocking eye mask 21.

[0035] Furthermore, such as Figure 1 , Figure 2 As shown, the blue light blocking goggles 21 have an avoidance notch 211 at the position corresponding to the user's nose bridge. The avoidance notch 211 is used to avoid the user's nose bridge. This allows the edge of the goggles to fit more closely to the face of medical personnel, effectively improving the protective seal of concave and convex areas of the face and preventing a decrease in blue light protection effect due to light leakage.

[0036] Furthermore, such as Figure 1 , Figure 2 As shown, the main frame body 1 is a ring-shaped frame, and a length adjustment device 11 is provided on the ring-shaped frame. The length adjustment device 11 is used to adjust the wearing diameter of the ring-shaped frame.

[0037] Furthermore, such as Figure 5 and Figure 7 As shown, a plurality of snap-fit ​​pieces 32 are provided on the outer side wall of the second support frame 3. These snap-fit ​​pieces 32 are evenly arranged along the extending direction of the second support frame 3. A snap-fit ​​groove 311 is provided on the protective face shield 31 at the position corresponding to the snap-fit ​​piece 32. The snap-fit ​​piece 32 and the snap-fit ​​groove 311 engage with each other, so that the protective face shield 31 is snapped onto the second support frame 3. Under prolonged and frequent use, the light transmittance and cleanliness of the protective face shield 31 will decrease, and its lifespan will be shortened. Therefore, the protective face shield 31 and the second support frame 3 are connected in a detachable manner to facilitate the replacement of the protective face shield 31 by medical personnel.

[0038] In this embodiment, the simple snap-fit ​​structure of the snap-fit ​​component 32 and the snap-fit ​​groove 311 allows medical personnel to easily and quickly change the protective face mask 31. The snap-fit ​​component 32 includes a snap-fit ​​ball and a connecting portion. The snap-fit ​​ball is fixedly connected to the second support member through the connecting portion. The diameter of the snap-fit ​​ball is larger than the diameter of the connecting portion, and the diameter of the snap-fit ​​ball is also larger than the diameter of the snap-fit ​​groove 311. This prevents the protective face mask 31 from loosening after being snapped onto the second support member.

[0039] Furthermore, the main frame body 1 is a silicone frame. The silicone frame has excellent elasticity. The silicone main frame body 1 has good fit, effectively improving the wearing comfort and stability of the main frame body 1.

[0040] Furthermore, such as Figure 2 , Figure 5 As shown, at least one of the main frame body 1, the first support frame 2, and the second support frame 3 is detachably connected to a lighting lamp 6. The lighting lamp 6 is provided with a hinge rod, the bending angle of which is adjustable so that the illumination direction of the lighting lamp 6 can be adjusted.

[0041] In summary, this application provides a multifunctional oral mask. When in use, the protective mask 31 and the blue light blocking goggles 21 can respectively protect against droplets and blue light emitted by the light-curing lamp, preventing respiratory infections caused by patient droplets and cumulative eye damage due to long-term blue light exposure for medical personnel. Medical personnel can quickly raise or lower the corresponding blue light blocking goggles 21 or protective mask 31 by turning a knob, effectively improving the ease of use of the equipment and increasing the work efficiency of medical personnel.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
