Technical Field

[0001] This application relates to the field of dental chair headrest technology, and more particularly to a detachable headrest and dental chair. Background Technology

[0002] Existing dental chair headrests have a fixed shape, making it convenient for patients to lie down. However, for patients whose hair is secured with hairbands, buns, or similar items, the hair pressing directly onto the headrest can cause the head position to become unstable, making it difficult to maintain a stable mouth opening position and affecting subsequent oral examinations or treatments. Leaving long hair loose can allow it to drift into the mouth during the procedure, further interfering with the examination or treatment. Furthermore, the hair may become contaminated with saliva or water during the examination or treatment, reducing the patient's experience. Additionally, the headrest can easily become soiled with saliva, stains, and germs during the oral examination or treatment, negatively impacting the experience of subsequent patients.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The first embodiment of this application provides a detachable headrest, including a headrest body 1 and a first constriction band 2. The headrest body 1 includes a first side portion 16, a first positioning hole 11, and a second side portion 17. The first positioning hole 11 is located between the second side portion 17 and the first side portion 16. The center of gravity of the first side portion 16 is higher than the center of gravity of the first positioning hole 11, and the center of gravity of the second side portion 17 is higher than the center of gravity of the first positioning hole 11. A first main body connecting portion 12 is provided on the first side portion 16, and a second main body connecting portion 13 is provided on the second side portion 17. The first constriction band 2... The shrink band 2 is provided with a first shrinkage hole 21 corresponding to the first positioning hole 11. One end of the first shrinkage band 2 is provided with a first connecting part 22 that is detachably connected to the first main body connecting part 12. The other end of the first shrinkage band 2 is provided with a second connecting part 23 that is detachably connected to the second main body connecting part 13. When the first connecting part 22 and the second connecting part 23 are connected to the first main body connecting part 12 and the second main body connecting part 13 respectively, the first shrinkage hole 21 corresponds to the first positioning hole 11, and the first shrinkage band 2 is in contact with the surface of the headrest body 1.

[0039] In this design, the center of gravity of the first side portion 16 of the headrest body 1 is higher than that of the first positioning hole 11, and the center of gravity of the second side portion 17 is higher than that of the center of the first positioning hole 11. This means the headrest body 1 has a structure that is lower in the middle and higher on both sides, facilitating the fixation of the patient's head onto the first positioning hole 11. Furthermore, the patient's hair can protrude through the first positioning hole 11, reducing interference from hair during oral examinations or treatments. The size of the first positioning hole 11 can be set according to actual needs. Specifically, it can be slightly adjusted based on common head dimensions. For example, if the average adult head length is 54-58cm, the diameter of the first positioning hole 11 can be 50cm.

[0040] The first compression hole 21 of the first compression band 2 corresponds to the first positioning hole 11 of the headrest body 1. The size of the first compression hole 21 can be adjusted to accommodate patients with different head shapes, making the detachable headrest suitable for patients with different head shapes or sizes. Furthermore, the first compression band 2 is connected to the first main body connecting part 12 and the second main body connecting part 13 of the headrest body 1 through the first connecting part 22 and the second connecting part 23, respectively. This allows the first compression band 2 to adhere to the surface of the headrest body 1, making it directly contact the patient. After oral examination or treatment, the first compression band 2 can be removed for cleaning, disinfection, and replacement, facilitating use by the next patient and preventing the headrest body 1 from becoming contaminated with stains and germs, thus improving the patient's experience.

[0041] The detachable connection between the first connecting part 22 and the first main body connecting part 12, and the detachable connection between the second connecting part 23 and the second main body connecting part 13, can be a fitting connection, a snap-fit ​​connection, etc. When it is a fitting connection, the first connecting part 22 and the second connecting part 23, and the first main body connecting part 12 and the second main body connecting part 13 are respectively a rough surface or a hook surface; preferably, the first main body connecting part 12 and the second main body connecting part 13 are rough surfaces to prevent the hook surface from being attached to other materials before the first compression band 2 is attached to the headrest body 1, resulting in poor adhesion with the first compression band 2.

[0042] The detachable headrest of this embodiment includes a headrest body 1 and a first compression band 2. The center of gravity of the first side 16 and the second side 17 of the headrest body 1 are both higher than the center of gravity of the first positioning hole 11, which makes it convenient for the patient's head to be fixed against the first positioning hole 11 under the action of gravity. The headrest body 1 can be fitted with a detachable first compression band 2. The first compression hole 21 on the first compression band 2 corresponds to the first positioning hole 11. The size of the first compression hole 21 can be adjusted to facilitate the fixation of patients with different head shapes and sizes or patients with hairbands or hair buns. The first compression band 2 can directly contact the patient and can be cleaned and replaced after oral examination or treatment to prevent the headrest body 1 from getting dirty and germs, thereby preventing bacterial infection and improving the patient's experience.

[0043] In some embodiments, the surface area of ​​the first constriction hole 21 is smaller than the surface area of ​​the first positioning hole 11. The surface area of ​​the first constriction hole 21 can be set according to the patient's head shape, size, and hair volume. The smaller surface area of ​​the first constriction hole 21 compared to the first positioning hole 11 allows it to constrict the first positioning hole 11 when the first constriction band 2 is attached to the headrest body 1. This enables patients with smaller head shapes or sizes to be positioned and fixed through the first constriction hole 21, preventing head displacement and avoiding interference with subsequent oral examinations or treatments.

[0044] That is, the first constriction band 2 can provide a certain support for the patient, thereby fixing the patient's head in the first constriction hole 21, preventing the patient's head from being unable to be fixed due to the first positioning hole 11 being too large.

[0045] Reference Figure 9 In some embodiments, the first compression band 2 is further provided with a first mesh area 24, the first compression hole 21 is located at the center of the first mesh area 24, and the first mesh area 24 is provided with a plurality of first holes 241, the surface area of ​​the first holes 241 being smaller than the surface area of ​​the first compression hole 21.

[0046] The first hole 241 of the first mesh area 24 is designed to allow the sparse hair on the patient's head to protrude, thereby fixing the position of the patient's head. It can be used for patients whose hair is fixed by different hairbands, hair buns, etc., and can fix the patient's head well without the need for the patient to remove the hairband or hair bun.

[0047] Specifically, the surface area of ​​the first hole 241 is smaller than the surface area of ​​the first constriction hole 21. That is, through the distribution of the first hole 241 and the first constriction hole 21, the hair can be extended to the corresponding position according to the hairstyle to prevent the hair from getting stuck.

[0048] In some embodiments, the surface area of ​​the first mesh area 24 is greater than or equal to the surface area of ​​the first positioning hole 11. When the first constriction band 2 is attached to the headrest body 1, the first mesh area 24 corresponds to the first positioning hole 11, and the patient's hair can extend from the first mesh area 24 to the first positioning hole 11, thereby fixing the position of the patient's head.

[0049] In some embodiments, the headrest body 1 further includes an upper part 18 and a lower part 19, with the first positioning hole 11 located between the upper part 18 and the lower part 19; the center of gravity of the upper part 18 is higher than the center of gravity of the first positioning hole 11, and the center of gravity of the lower part 19 is lower than the center of gravity of the first positioning hole 11.

[0050] The center of gravity of the upper part 18 is higher than that of the first positioning hole 11, which can prevent the patient's head from shifting upwards during examination or treatment, thus preventing poor examination or treatment results. The center of gravity of the lower part 19 is lower than that of the first positioning hole 11, which is more ergonomic and makes the patient's cervical spine more comfortable.

[0051] Reference Figure 4 , Figure 5 and Figure 6In some embodiments, the upper part 18 is provided with a third main body connecting part 14, and the lower part 19 is provided with a fourth main body connecting part 15; the detachable headrest also includes a second compression band 3, the second compression band 3 is provided with a second compression hole 31 corresponding to the first positioning hole 11, one end of the second compression band 3 is provided with a third connecting part 32 detachably connected to the third main body connecting part 14, and the other end of the second compression band 3 is provided with a fourth connecting part 33 detachably connected to the fourth main body connecting part 15.

[0052] When the second constriction band 3 is connected to the third main body connecting part 14 and the fourth main body connecting part 15 through the third connecting part 32 and the fourth connecting part 33 respectively, the second constriction hole 31 corresponds to the first positioning hole 11. By adjusting the size of the second constriction hole 31, it is convenient to fix the head of patients with different head shapes or sizes. Specifically, the second constriction band 3 can be attached above the first constriction band 2, or attached between the first constriction band 2 and the headrest body 1. It can be combined with the first constriction band 2 to improve the support for the patient's head and improve the comfort of the patient's head. Furthermore, the combination of the first constriction band 2 and the second constriction band 3 can increase the contact area with the patient, thereby preventing the headrest body 1 from being contaminated with stains or germs during oral examinations or treatments.

[0053] The detachable connection between the third connecting part 32 and the third main body connecting part 14, and the detachable connection between the fourth connecting part 33 and the fourth main body connecting part 15, can be a fitting connection, a snap-fit ​​connection, etc. When it is a fitting connection, the third connecting part 32 and the fourth connecting part 33, and the third main body connecting part 14 and the fourth main body connecting part 15 are respectively a rough surface or a hook surface; preferably, the third main body connecting part 14 and the fourth main body connecting part 15 are rough surfaces to prevent the hook surface from being attached to other materials before the second compression band 3 is attached to the headrest body 1, resulting in poor adhesion with the second compression band 3.

[0054] Reference Figure 7 In some embodiments, the surface area of ​​the second constricting hole 31 is smaller than the surface area of ​​the first positioning hole 11. Depending on the size of the second constricting hole 31, it can be combined with the first positioning hole 11, making the detachable headrest suitable for patients with smaller head shapes or sizes.

[0055] Specifically, the size of the second compression hole 31 can be the same as that of the first compression hole 21. When the first compression band 2 and the second compression band 3 are attached to the headrest body 1, the first compression hole 21 and the second compression hole 31 are used in correspondence to enhance the support for the head of patients with small head shape or size.

[0056] Reference Figure 9In some embodiments, the second compression band 3 is further provided with a second mesh area 34, the second compression hole 31 is located at the center of the second mesh area 34, and a plurality of second holes 341 are provided on the second mesh area 34, the surface area of ​​the second holes 341 being smaller than the surface area of ​​the second compression hole 31.

[0057] The second hole 341 in the second mesh area 34 serves the same purpose as the first hole 241: to allow sparse hair on the patient's head to protrude, thereby securing the patient's head. This method is suitable for patients whose hair is secured with various headbands or buns, without requiring the patient to remove the headband or bun, and can effectively secure the patient's head. The shape and size of the first hole 241 and the second hole 341 can be set according to actual needs and are not specifically limited.

[0058] Specifically, the surface area of ​​the second hole 341 is smaller than that of the second constriction hole 31. That is, through the distribution of the second hole 341 and the second constriction hole 31, the hair can be extended to the corresponding position according to the hairstyle to prevent the hair from getting stuck.

[0059] Similarly, the surface area of ​​the second mesh area 34 is preferably greater than or equal to the surface area of ​​the first positioning hole 11. When the second constriction band 3 is in contact with the headrest body 1, the second mesh area 34 corresponds to the second positioning hole, and the patient's hair can extend from the second mesh area 34 to the second positioning hole, thereby fixing the position of the patient's head.

[0060] Reference Figure 8 In some embodiments, the first connecting portion 22 is provided with a plurality of first connecting protrusions 221, and the second connecting portion 23 is provided with a plurality of second connecting protrusions 231; the first main body connecting portion 12 is provided with a first connecting groove corresponding to the first connecting protrusions 221; and the second main body connecting portion 13 is provided with a second connecting groove corresponding to the second connecting protrusions 231.

[0061] The first compression band 2 and the headrest body 1 are detachably connected by the engaging connection between the first connecting protrusion 221 and the first connecting groove, and the second connecting protrusion 231 and the second connecting groove, which facilitates the replacement and installation of the first compression band 2.

[0062] The number of first connecting protrusions 221 corresponds one-to-one with the number of first connecting grooves, and the number of second connecting protrusions 231 corresponds one-to-one with the number of second connecting grooves. Preferably, there are two. Specifically, two first connecting protrusions 221 are arranged vertically on the first connecting part 22, and two second connecting protrusions 231 are arranged vertically on the second connecting part 23, which can facilitate the complete unfolding of the first compression band 2.

[0063] Similarly, connecting protrusions can also be provided on the third connecting part 32 and the fourth connecting part 33, and connecting grooves can also be provided on the third main body connecting part 14 and the fourth main body connecting part 15. The second compression band 3 and the headrest body 1 can be detachably connected by the engaging connection between the connecting protrusion and the connecting groove.

[0064] Reference Figure 10 The second embodiment of this application provides a dental chair, including a dental chair body 5 and a detachable headrest as described in the first embodiment or any of its embodiments, wherein the dental chair body 5 is connected to the detachable headrest.

[0065] In this embodiment, the dental chair body 5 is connected to the headrest body 1 of the detachable headrest. The headrest body 1 can be detachably connected to the headrest body 1 through the first compression band 2. When the patient is undergoing oral examination or treatment, the first compression band 2 is attached to the surface of the headrest body 1, thereby reducing stains or bacteria on the headrest body 1. The first compression band 2 can be cleaned or replaced to facilitate use by different patients. Furthermore, the size of the first compression hole 21 of the first compression band 2 can be adjusted to accommodate the head of patients with different head shapes and sizes.

[0066] In some embodiments, the dental chair also includes a backrest 4, a footrest 6, and an armrest 8. One end of the backrest 4 is connected to the dental chair body 5, and the other end is connected to a detachable headrest. The footrest 6 is connected to the end of the dental chair body 5 away from the backrest 4. The armrest 8 is located on one side of the dental chair body 5.

[0067] The backrest 4 is used to support the patient's back, the dental chair body 5 is used to support the patient's lower body, and the footrest 6 is used to support the patient's feet. The footrest 6 can be fitted with a soiling-proof film, which can be replaced after one use, allowing the patient to use it without removing their shoes and socks. The armrests 8 help the patient to support themselves and stand up. Specifically, the backrest 4, the dental chair body 5, and the footrest 6 can be connected as a single unit or can be detached and installed separately.

[0068] In some embodiments, the dental chair also includes a base 7 located below the main body 5 of the dental chair for supporting the main body 5. The base 7 may also contain a power unit capable of adjusting the tilt angle of the base 7 relative to the horizontal plane, thereby facilitating user operation.

[0069] In summary, this application provides a detachable headrest and dental chair. The detachable headrest includes a headrest body and a first compression band. The center of gravity of the first and second sides of the headrest body is higher than the center of gravity of the first positioning hole, which facilitates the patient's head to be fixed against the first positioning hole under the action of gravity. The detachable first compression band can be fitted onto the headrest body. The first compression hole on the first compression band corresponds to the first positioning hole. The size of the first compression hole can be adjusted to facilitate the fixation of patients with different head shapes and sizes, or patients with headbands or hair buns. Furthermore, the first compression band can directly contact the patient and can be cleaned and replaced after oral examinations or treatments to prevent the headrest body from getting dirty or contaminated with bacteria, thereby improving the patient's experience.
