[0035] The dental medical equipment holding device 1000 according to this embodiment can be installed in the dental chair 10 shown in Fig. 1, thereby increasing the number of dental medical equipment 20 used in dental treatment without requiring additional dentists or dental hygienists. In this case, the dental medical equipment holding device 1000 can be installed in the headrest support 12 of the existing dental chair 10 and used during dental treatment.

[0036] In the following, in this embodiment, a case where the medical instrument holder part 300 is connected to the headrest part 100 via the rod adjusting part 200 will be described. However, this is not limited thereto, and the rod adjusting part 200 may be omitted and the medical instrument holder part 300 may be directly connected to the headrest part 100.

[0037] 2 to 5, the headrest unit 100 of this embodiment can be detachably installed and fixed to the headrest support 12 of the dental chair 10. In this case, the headrest unit 100 is preferably formed to have a structure that can accommodate various thicknesses and widths of the headrest support 12 so that it can be installed regardless of the type of dental chair 10.

[0038] For example, the headrest portion 100 may include a headrest bracket 120 and a headrest panel 140 .

[0039] The headrest bracket 120 may be detachably installed on the headrest support 12. The headrest bracket 120 may be formed so that its position can be adjusted in the vertical direction along the headrest support 12. In addition, a plurality of rod adjustment units 200 may be connected to both sides of the headrest bracket 120. For reference, the detailed structure of the headrest bracket 120 of this embodiment will be described again below.

[0040] The headrest panel 140 may be coupled to the front portion of the headrest bracket 120 so as to support the head of a patient seated in the dental chair 10. For example, the headrest panel 140 may be fastened and fixed to the front portion of the headrest bracket 120 with a plurality of frame fastening members 144.

[0041] Here, a positioning groove may be formed on the front surface of the headrest bracket 120, and a positioning protrusion may be formed on the rear surface of the headrest panel 140 to be inserted into the positioning groove of the headrest bracket 120. Using the positioning groove and the positioning protrusion, the headrest panel 140 can be stably positioned at the correct position on the headrest bracket 120.

[0042] Meanwhile, a neck support 110 may be detachably disposed on the headrest panel 140. The neck support 110 is intended to more comfortably and stably support the head of a patient seated in the dental chair 10, and may be detachably fixed to a hook-and-loop fastener member 142 disposed on the front surface of the headrest panel 140.

[0043] The detailed configuration of the headrest bracket 120 will be described below with reference to FIGS.

[0044] As shown in FIGS. 3 to 5, the headrest bracket 120 of this embodiment may include a bracket body 122 and a fixed handle 124.

[0045] A support insertion hole 122a for inserting the headrest support 12 therethrough may be formed in the center of the bracket body 122, and a headrest panel 140 may be fastened to the front surface of the bracket body 122 in a fastening manner.

[0046] Here, the support insertion hole 122a may be provided with a multi-step cross-sectional shape formed in a stepped shape with a plurality of thicknesses T1, T2 and widths W1, W2 corresponding to the thicknesses T1, T2 and widths W1, W2 of the headrest support 12. The headrest support 12 may be formed with different thicknesses T1, T2 and widths W1, W2 depending on the type of dental chair 10. Therefore, the headrest support 12 may be disposed in a specific space within the support insertion hole 122a, and the specific space within the support insertion hole 122a may correspond to a space having a thickness and width corresponding to the thicknesses T1, T2 and widths W1, W2 of the headrest support 12.

[0047] For example, the bracket body 122 may include a front bracket 126 , a rear bracket 127 , and a bracket fastener 128 .

[0048] The front bracket 126 may be disposed in front of the headrest support 12. The headrest panel 140 may be fastened to a front portion of the front bracket 126. Meanwhile, a front insertion hole 126a forming a front portion of the support insertion hole 122a may be formed in a rear portion of the front bracket 126. The front insertion hole 126a may be formed in a stepped shape with a multi-step structure corresponding to the thicknesses T1, T2 and widths W1, W2 of the headrest support 12.

[0049] The rear bracket 127 may be disposed at the rear of the headrest support 12 to face the front bracket 126. A plurality of rod connecting portions 130 having internal threads formed on the inner circumferential surfaces thereof may be formed on both sides of the rear bracket 127 to individually connect a plurality of rod adjusting portions 200. Meanwhile, a rear insertion hole 127a forming a rear portion of the support insertion hole 122a may be formed on the front surface of the rear bracket 127. The rear insertion hole 127a may be formed in a stepped shape with multiple steps corresponding to the thicknesses T1, T2 and widths W1, W2 of the headrest support 12.

[0050] A plurality of bracket fastening members 128 may be fastened and fixed to the front bracket 126 and the rear bracket 127 with the headrest support 12 placed between the front insertion hole 126a and the rear insertion hole 127a.

[0051] The multi-stage structure of the support insertion hole 122a formed by the front insertion hole 126a and the rear insertion hole 127a as shown in Fig. 5 will be described in more detail.

[0052] 5, the depth (D1+D2) of the support insertion hole 122a, which is the sum of the depth D1 of the front insertion hole 126a and the depth D2 of the rear insertion hole 127a, may be equal to the thickness T1 of the headrest support 12, and the thickness W1 of the rear insertion hole 127a may be equal to the width W1 of the headrest support 12. Therefore, the headrest support 12 shown by the solid line is inserted into the front insertion hole 126a and the rear insertion hole 127a at the same time, and left-right movement may be prevented by the rear insertion hole 127a.

[0053] 5, the depth D1 of the front insertion hole 126a may be equal to the thickness T2 of the headrest support 12, and the thickness W2 of the front insertion hole 126a may be equal to the width W2 of the headrest support 12. Therefore, the dotted headrest support 12 is inserted only into the front insertion hole 126a, and the front insertion hole 126a may prevent it from moving left and right.

[0054] The fixing handle 124 may be movably disposed on the rear surface of the bracket body 122 by a screw fastening method. That is, when the fixing handle 124 is rotated in the forward direction, the headrest support 12 is inserted into the support insertion hole 122a and fastened and fixed to the bracket body 122. On the other hand, when the fixing handle 124 is rotated in the reverse direction, the fastened state of the headrest support 12 can be released.
