Description

Technical Field

[0001] This utility model belongs to the field of curing protection technology, and more specifically, it relates to a safety protection device for light curing lamp heads. Background Technology

[0002] A light-curing machine (dental light-sensitive resin curing machine) is a machine used by dentists to cure light-sensitive resin materials when restoring teeth. A light-curing machine consists of a light source and control circuitry; externally, it can be viewed as a main body and a light guide. In existing light-curing machines, the light guide emits blue light during curing, some of which can shine into and harm the eyes of medical personnel. This is mainly because some light guides in light-curing machines are made of transparent material, allowing blue light to escape through the sidewalls, thus posing a safety risk. Furthermore, the light guide may come into contact with the mouths of different patients, requiring sterilization before each use to avoid the risk of cross-infection. Utility Model Content

[0003] The purpose of this invention is to provide a safety protection device for the light curing lamp head, which aims to solve the problem that the blue light emitted by the light guide rod of the light curing machine can damage the eyes of medical staff and pose a risk of cross-infection to patients.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a safety protection device for a light curing lamp head, comprising:

[0005] A light-shielding cover, which can be detachably fitted onto the light guide bar of the UV curing lamp, is used to prevent cross-contamination;

[0006] A filter cover is disposed at the end of the light-shielding sleeve away from the light-curing lamp body. The open end of the filter cover is positioned facing the light outlet of the light guide rod to control the light output range and filter light. The filter cover has a certain light transmittance.

[0007] A shaping ring is disposed inside the filter cover to shape the filter cover.

[0008] In one possible implementation, the shaping ring passes through the end of the filter mask away from the light-shielding sleeve.

[0009] In one possible implementation, the filter is provided with a connecting ring at the end near the light-shielding sleeve, the connecting ring being used to position the filter on the light guide rod.

[0010] In one possible implementation, the filter cover includes a support film and a filter film, the filter film being disposed outside the support film, and both the support film and the filter film being connected between the connecting ring and the shaping ring.

[0011] In one possible implementation, the supporting membrane is provided with a reflective film on the inner side near the connecting ring.

[0012] In one possible implementation, the filter film is adhered to the support film.

[0013] In one possible implementation, a plurality of pleats for deformation are provided circumferentially along the supporting membrane and the filter membrane.

[0014] In one possible implementation, a fill light is mounted on the filter.

[0015] In one possible implementation, there are multiple light-shielding sleeves, which are stacked outwards in sequence.

[0016] In one possible implementation, a dotted line is provided along the length of the light-shielding sleeve.

[0017] The beneficial effects of the light curing lamp head safety protection device provided by this utility model are as follows: Compared with the prior art, the light curing lamp light guide rod of this utility model is detachably fitted with a light shield, the filter is set at the end of the light shield away from the light curing lamp body, and the shaping ring is set inside the filter.

[0018] In practical applications, the light-shielding sleeve can block light escaping along the length of the light guide rod. Because the filter has an open end facing the light outlet of the light guide rod, it can filter the transmitted light. The filter also has a certain light transmittance, making it easy to observe the position of the light outlet during curing. The shaping ring can change the shape and size of the filter, facilitating operation and adjusting the light output range of the curing lamp. This application, while ensuring safe use, can largely avoid harm to patients and doctors from the curing lamp's light, and is highly applicable and easy to use. Attached Figure Description

[0023] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Please see Figure 1 and Figure 2 The safety protection device for the UV-curing lamp head provided by this utility model will now be described. The safety protection device for the UV-curing lamp head includes: a light-shielding sleeve 3, a light filter 9, and a shaping ring 8. The light-shielding sleeve 3 is detachably fitted onto the light guide rod 2 of the UV-curing lamp to prevent cross-contamination. The light filter 9 is located at the end of the light-shielding sleeve 3 away from the UV-curing lamp body 1, with its open end facing the light outlet of the light guide rod 2 to control the light output range and filter light; the light filter 9 has a certain light transmittance. The shaping ring 8 is disposed inside the light filter 9 to shape the light filter 9.

[0025] The beneficial effects of the light curing lamp head safety protection device provided by this utility model are as follows: Compared with the prior art, in the light curing lamp head safety protection device of this utility model, the light curing lamp light guide rod 2 is detachably fitted with a light shield 3, the light filter 9 is set at the end of the light shield 3 away from the light curing lamp body 1, and the shaping ring 8 is set inside the light filter 9.

[0026] In practical applications, the light-shielding sleeve 3 can block light escaping along the length of the light guide rod 2. Since the filter 9 has an open end facing the light outlet of the light guide rod 2, it can filter the transmitted light. Because the filter 9 has a certain light transmittance, it is convenient to observe the position of the light outlet of the light guide rod 2 during the curing operation. The shaping ring 8 can change the shape and size of the filter 9, thereby facilitating operation and adjusting the light output range of the light curing lamp. This application, while ensuring safe use, can largely avoid harm to patients and doctors from the light of the curing lamp, and is highly applicable and easy to use.

[0027] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1The shaping ring 8 is inserted at the end of the filter 9 furthest from the light-shielding sleeve 3. The shaping ring 8 can be considered a metal ring and possesses certain fatigue resistance characteristics, meaning it will not undergo significant plastic deformation even after being bent multiple times. Under the action of the shaping ring 8, the entire filter 9 can undergo substantial deformation. In actual operation, the shaping ring 8 can be deformed by squeezing or stretching according to the actual usage requirements. This allows the filter 9 to be stabilized in a suitable shape under the action of the shaping ring 8.

[0028] The end of the filter 9 has a certain volume. The shaping ring 8 is inserted inside the filter 9, which facilitates subsequent disinfection and avoids the problem of the shaping ring 8 falling off from the filter 9.

[0029] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 A connecting ring 4 is provided at the end of the filter 9 near the light-shielding sleeve 3. The connecting ring 4 is used to position the filter 9 on the light guide rod 2. To facilitate the positioning of the filter 9, a connecting ring 4 is provided at the end of the filter 9 near the light guide rod 2, and the filter 9 can be directly adhered to the connecting ring 4. It should be noted that the connecting ring 4 itself has a certain degree of flexibility. In practical applications, the connecting ring 4 can be a rubber ring, allowing it to slide on the light guide rod 2. Doctors can adjust the position of the connecting ring 4 relative to the light guide rod 2 according to the patient's condition and usage habits, thereby ensuring that the filter 9 can effectively prevent the light emitted from the light guide rod 2 from shining outward.

[0030] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 The filter cover 9 includes a support film 6 and a filter film 5. The filter film 5 is located outside the support film 6, and both the support film 6 and the filter film 5 are connected between the connecting ring 4 and the shaping ring 8. The filter cover 9 needs to be able to filter the light emitted by the light guide 2. However, since the filter film 5 itself has relatively low structural strength and lacks a certain load-bearing capacity, a support film 6 is provided inside the filter film 5. The support film 6 first comes into contact with the light emitted by the light guide 2, and the support film 6 can reflect a certain amount of light, thereby allowing more light to illuminate the oral cavity. Due to the partial reflection of light by the support film 6, the amount of light passing through the filter film 5 is reduced, thus protecting the doctor's eyes and improving safety.

[0031] The shaping ring 8 can be directly placed between the filter film 5 and the support film 6, and the shaping ring 8 can be wrapped and positioned by the filter film 5 and the support film 6.

[0032] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2A reflective membrane 7 is provided on the inner side of the support membrane 6 near the connecting ring 4. The filter 9 is shaped like a trumpet and can be considered as a conical structure extending from the light guide rod 2 to the light outlet of the light guide rod 2. In this case, the innermost part near the filter 9 will not affect the doctor's operation because both the filter membrane 5 and the support membrane 6 have a certain degree of light transmittance. The doctor can complete the light curing operation through the edges of the filter membrane 5 and the support membrane 6. The reflective membrane 7 is provided on the inner side of the support membrane 6, which can reflect the light into the oral cavity as much as possible without affecting the operation. Furthermore, the presence of the filter 9 can ensure that the light is focused on the designated location, preventing the light from scattering and improving the light concentration.

[0033] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 The filter film 5 is adhered to the support film 6. The filter film 5 is located on the back of the support film 6 and is detachably connected to the support film 6, typically by adhesion. The thickness and number of filter films 5 are adjustable, and multiple filter films 5 can be sequentially placed on the support film 6. The filter film 5 needs to be specifically selected according to the type of light generated by the UV curing machine.

[0034] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 Multiple pleats are provided circumferentially along the support film 6 and the filter film 5 to allow for deformation. The filter 9 in this application requires specific adjustments based on actual usage requirements; these adjustments can be in shape and size. The shaping ring 8 aims to stabilize the shape of the deformed filter 9. To achieve the aforementioned effects, multiple pleats are provided on the support film 6 and the filter film 5. The purpose of these pleats is to provide deformation allowance for the deformation of the support film 6 and the filter film 5.

[0035] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 A supplementary light is installed on the filter 9. After deformation, an expansion sleeve can be set inside the support membrane 6. The purpose of the expansion sleeve is to stabilize the shape of the filter 9. At this time, even if the filter 9 is subjected to external force, the structural stability can be guaranteed, thus facilitating the completed curing operation. The curing effect of the tooth can be observed through the supplementary light, which facilitates subsequent operations.

[0036] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2Multiple light-shielding sleeves 3 are stacked outwards in sequence. This application considers the need to avoid cross-contamination in scenarios involving multiple uses. To achieve the aforementioned technical effect, multiple light-shielding sleeves 3 are used, and these sleeves are sequentially fitted onto the light guide rod 2. After each use, the light-shielding sleeves 3 are removed for convenient subsequent use. It should be noted that the filter 9 also needs to be replaced or disinfected at this time.

[0037] For some embodiments of the UV curing lamp holder safety protection device provided in this application, please refer to... Figure 1 and Figure 2 The light-shielding sleeve 3 has dotted breaks along its length. These breaks allow the light-shielding sleeve 3 to be removed in a manner similar to that of cling film, making the operation convenient and safe.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
