Description

Technical Field

[0001] The utility model relates to the technical field of headrests, in particular to a headrest for a dental treatment chair. Background Art

[0002] During dental treatment, patients usually need to lie on a dental chair and turn their heads to a certain angle to facilitate the doctor's treatment. Especially when filling or cleaning teeth, patients not only need to keep their mouths open for a long time, but also need to keep the head angle fixed for a long time, which is very tiring.

[0003] The existing dental treatment bed headrests are usually simple in structure and do not support both sides of the patient's head. For example, the Chinese utility model patent with the authorization company number CN 219230546 U has a headrest structure that simply supports the back of the head.

[0004] Although many headrests in the prior art have limiting mechanisms, most of them fix the angle of the head through a completely fixed mechanism. For example, in craniotomy, in order to prevent the patient's head from moving, the patient's head must be completely fixed by a fixing mechanism. However, for work such as dental treatment, the patient's head is sometimes movable, and a completely fixed method may cause discomfort to the patient's neck.

[0005] Therefore, the purpose of the present application is to provide a dental treatment chair headrest that can support both sides of the patient's head during treatment and improve the patient's comfort during treatment. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a dental treatment chair headrest to solve the above problem.

[0007] To achieve the above-mentioned purpose, the utility model provides a headrest for a dental treatment chair, comprising a headrest plate, two movable frames movably arranged on both sides of the headrest plate, a head traction mechanism and a head support mechanism arranged on the two movable frames, a chin rest being connected between the two movable frames, the head traction mechanism comprising a head restraint belt and a traction belt, one end of the traction belt being fixedly connected to the movable frame, and the other end of the traction belt being fixedly connected to the side of the head restraint belt, the head support mechanism comprising a support screw and a support ball, the support screw being threadedly connected to the movable frame, and the support ball being fixedly connected to the support screw.

[0008] Beneficial effects: The dental treatment chair headrest of the utility model includes a headrest plate, a head restraint belt, a support screw and a support ball. Patients can adapt to treatment needs by adjusting their head posture without having to maintain an uncomfortable posture all the time. In addition, this design is also flexible, allowing patients to turn their heads when needed, rather than always keeping them at a fixed angle. This helps reduce the fatigue of patients when they maintain the same posture for a long time, and improves the comfort of treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is combined with Figure 1-4 The specific implementation modes of the present utility model are further described in detail.

[0015] Embodiment 1

[0016] A dental treatment chair headrest comprises a headrest plate 10, two movable frames 20 movably arranged on both sides of the headrest plate 10, a head traction mechanism 30 and a head support mechanism 40 arranged on the two movable frames 20, a chin rest 50 is connected between the two movable frames 20, the movable frame 20 can slide on the surface of the headrest plate 10 to adjust the position, the head traction mechanism 30 can pull from one side of the patient's head, and the head support mechanism 40 can support from the other side of the patient's head. With the combination of the two, the patient's head can be kept at a relatively fixed angle. In addition, the chin rest 50 can be arranged to assist the patient's chin to be lifted, thereby improving comfort. It is worth mentioning that the head traction mechanism 30, the head support mechanism 40 and the chin rest 50 are not completely fixed structures, that is, the patient's head is movable, which is described in detail below.

[0017] In this embodiment, the head traction mechanism 30 includes a head restraint belt 31 and a traction belt 32, one end of the traction belt 32 is fixedly connected to the movable frame 20, and the other end of the traction belt 32 is fixedly connected to the side of the head restraint belt 31. The head support mechanism 40 includes a support screw 41 and a support ball 42, the support screw 41 is threadedly connected to the movable frame 20, and the support ball 42 is fixedly connected to the support screw 41. When in use, the patient first lies on the treatment chair, rests the head on the headrest board 10, and then puts the head restraint belt 31 on the head, and tilts the head to one side according to the instructions of the dentist to facilitate the treatment of the teeth, such as Figure 2 As shown, when the patient faces the left side, the head restraint belt 31 is pulled from the right side by the traction belt 32, and the head is supported from the left side by the support screw 41 and the support ball 42. In this way, the patient can easily keep the head at a certain angle. During the treatment intervals, the patient can turn the head to the right. At this time, the traction belt 32 and the support ball 42 will not cause any restrictions, so that the patient can move his head.

[0018] Specifically, two slots 11 are symmetrically provided on both sides of the headrest plate 10, and two slide rails 12 are fixed in the two slots 11. The lower end of the movable frame 20 is slidably connected in the slide rail 12, and an adjusting screw 13 is rotatably installed in the slide rail 12. The adjusting screw 13 is threadedly connected to the movable frame 20. When in use, the adjusting screw 13 can be manually rotated, and the movable frame 20 is driven to slide in the slot 11 by the rotation of the adjusting screw 13 to adjust the position of the movable frame 20.

[0019] The chin support 50 includes a chin support strap 51, and both ends of the chin support strap 51 are fixedly connected to the two movable frames 20 respectively. When in use, the chin support 50 is put on the patient's chin, and the chin is supported by the chin support 50, which saves more effort when the patient needs to raise his face.

[0020] The traction belt 32 is provided with an elastic adjustment buckle 33, which is a prior art and is commonly found on backpack straps, and can adjust the length of the strap.

[0021] Embodiment 2

[0022] Different from the second embodiment, the chin support 50 includes a chin support strap 51a, a sliding column 51b is slidably provided at the head of the support screw 41, a support ball 42 is fixed to the sliding column 51b, a spring 51d is connected between the sliding column 51b and the support screw 41, and a connecting ring 51c is rotatably installed on the sliding column 51b, and the chin support strap 51a is fixedly connected to the connecting ring 51c.

[0023] The above structure is described in detail below. After the patient's head rests on the headrest board 10, the head traction mechanism 30 and the head support mechanism 40 limit the two sides so that the head is kept at an angle, and then the chin support strap 51a is put on the chin. No matter which side the head rests on, the support ball 42 will be squeezed inward, thereby compressing the spring 51d and tightening the chin traction strap 51a. Conversely, when the patient needs to move his head, when he turns his head to the opposite side, the support ball 42 loses its squeezing, and under the elastic force of the spring 51d, the slide column 51b slides outward, thereby loosening the chin support strap 51a, so that the patient can move his chin up and down slightly.

[0024] The chin support strap 51 is provided with a tension adjustment buckle 33 .

[0025] Working principle: When the dental treatment chair headrest of the utility model is in use, the patient first lies on the treatment chair and leans the head against the headrest plate 10, then puts the head restraint belt 31 on the head, and according to the instruction of the dentist, tilts the head to one side to facilitate the treatment of the teeth. The side facing the head is supported by the support screw 41 and the support ball 42, and the side facing the back of the head is pulled by the traction belt 32. Then, it can be selected whether to put the chin support belt 51a on the chin according to the needs. The patient will be very tired if the head is tilted to one side for a long time. When it is necessary to move the head, the head can be turned in the opposite direction. At this time, the traction belt 32 and the support ball 42 will not produce restrictions, so that the patient can move the head. In addition, when the head is turned to the opposite side, the support ball 42 loses its compression, and under the elastic force of the spring 51d, the sliding column 51b will slide outward, thereby loosening the chin support belt 51a, so that the patient can move the chin up and down slightly, which has better comfort compared to a completely fixed headrest structure.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
