This disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like reference numerals in the drawings denote like elements.

[0037] FIG. 1 schematically illustrates a dental chair 10 to which a holding device 1000 for dental medical devices according to an embodiment of the present disclosure is to be applied, FIG. 2 illustrates the holding device 1000 for dental medical devices which is to be applied to the dental chair 10 shown in FIG. 1. FIG. 3 schematically illustrates the holding device 1000 for dental medical devices shown in FIG. 2, and FIGS. 4 and 5 respectively illustrate the perspective view and plan view of a headrest 100 shown in FIG. 3.

[0038] Referring to FIGS. 1 to 3, the holding device 1000 for dental medical devices according to an embodiment of the present disclosure may include a headrest 100, rod adjusters 200, and a medical device holder 300.

[0039] The holding device 1000 for dental medical devices according to the embodiment may be installed on the dental chair 10 shown in FIG. 1, so that the number of dental medical devices 20 used for dental treatment may be increased without additional involvement of a doctor or a nurse. Here, the holding device 1000 for dental medical devices may be intalled on a headrest support 12 provided on an existing dental chair 10 and used for dental treatment.

[0040] Hereinafter, in this embodiment, it is described that the medical device holder 300 is connected to the headrest 100 via the rod adjusters 200. However, the present disclosure is not limited to this, and it is also possible to omit the rod adjusters 200 and to directly connect the medical device holder 300 to the headrest 100.

[0041] Referring to FIGS. 2 to 5, the headrest 100 of this embodiment may be detachably installed and fixed to the headrest support 12 of the dental chair 10. Here, it is preferable that the headrest 100 is formed in a structure corresponding to headrest supports 12 with various thicknesses and widths so that it can be installed regardless of the kind of the dental chair 10.

[0042] For example, the headrest 100 may include a headrest bracket 120 and a headrest panel 140.

[0043] The headrest bracket 120 may be detachably installed on the headrest support 12. The headrest bracket 120 may be formed so as to be positionally adjustable in upper and lower directions along the headrest support 12. In addition, a plurality of rod adjusters 200 may be connected to each of opposite sides of the headrest bracket 120. For reference, a detailed structure of the headrest bracket 120 of the embodiment is described again below.

[0044] The headrest panel 140 may be coupled with a front surface of the headrest bracket 120 to support a patient sitting on the dental chair 10. For example, the headrest panel 140 may be fixedly fastened to the front surface of the headrest bracket 120 by a plurality of frame-fastening members 144.

[0045] Here, positioning grooves may be formed on the front surface of the headrest bracket 120, and positioning protrusions to be inserted into the positioning grooves of the headrest bracket 120 may be formed to protrude from a rear surface of the headrest panel 140. By using the positioning grooves and the positioning protrusions, the headrest panel 140 may be stably placed at a correct position of the headrest bracket 120.

[0046] Meanwhile, a neck support 110 may be detachably placed on the headrest panel 140. The neck support 110 is intended to support more comfortably and stably the head of a patient sitting on the dental chair 10, and may be detachably fixed to Velcro members 142 arranged on the front surface of the headrest panel 140.

[0047] Hereinfter, a detailed configuration of the headrest bracket 120 FIGS. 3 to 5 is examined.

[0048] As shown in FIGS. 3 to 5, the headrest bracket 120 of the embodiment may include a bracket body 122 and a fixing handle 124.

[0049] A support-inserted hole 122a, through which the headrest support 12 is to be inserted to pass, may be formed in the center of the bracket body 122, and the headrest panel 140 may be coupled to the front surface of the bracket body 122 in a fastening manner.

[0050] Here, the support-inserted hole 122a may have a cross-sectional shape having a multi-stage structure formed stepwise according to a plurality of thicknesses T1 and T2 and widths W1 and W2 that correspond to thicknesses T1 and T2 and widths W1 and W2 of the headrest support 12. In addition, the headrest support 12 may have different thicknesses T1 and T2 and widths W1 and W2 depending upon the kind of the dental chair 10. Accordingly, the headrest support 12 may be placed within a specific space in the support-inserted hole 122a, and the specific space of the support-inserted hole 122a may have thicknesses and widths corresponding to the thicknesses T1 and T2 and widths W1 and W2 of the headrest support 12.

[0051] For example, the bracket body 122 may include a front bracket 126, a rear bracket 127, and bracket-fastening members 128.

[0052] The front bracket 126 may be placed at the front of the headrest support 12. The headrest panel 140 may be coupled to the front surface of the front bracket 126 in a fastening manner. Meanwhile, a front insertion hole 126a forming a front part of the support-inserted hole 122a may be formed at the rear of the front bracket 126. The front insertion hole 126a may be formed stepwise in a multi-stage structure corresponding to the thicknesses T1 and T2 and widths W1 and W2 of the headrest support 12.

[0053] The rear bracket 127 may be placed at the rear of the headrest support 12 to face the front bracket 126. A plurality of rod connectors 130 whose inner peripheral surface has a female screw for connecting each of a plurality of rod adjusters 200 may be formed on opposite sides of the rear bracket 127. Meanwhile, a rear insertion hole 127a forming the rear part of the support-inserted hole 122a may be formed on the front surface of the rear bracket 127. The rear insertion hole 127a may be formed stepwise a multi-stage structure corresponding to the thicknesses T1 and T2 and widths W1 and W2 of the headrest support 12.

[0054] The bracket-fastening members 128 may be fixedly fastened to the front bracket 126 and the rear bracket 127 in a state where the headrest support 12 is placed between the front insertion hole 126a and the rear insertion hole 127a.

[0055] Referring to FIG. 5, the multi-stage structure of the support-inserted hole 122a formed by the front insertion hole 126a and the rear insertion hole 127a is described in more detail. That is, the support-inserted hole 122a of FIG. 5 may be provided as a two-stage structure for selective insertion of the headrest support 12 indicated by solid lines and dotted lines.

[0056] In the case of the headrest support 12 indicated by solid lines of FIG. 5, the depth D1+D2 of the support-inserted 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 the same as the thickness T1 of the headrest support 12, and the height W1 of the rear insertion hole 127a may be the same as the width W1 of the headrest support 12. Accordingly, the headrest support 12 indicated by the solid lines may be inserted into both the front insertion hole 126a and the rear insertion hole 127a, so that movement in the left and right direction may be prevented by the rear insertion hole 127a.

[0057] On the other hand, in the case of the headrest support 12 indicated by dotted lines shown in FIG. 5, the depth D1 of the front insertion hole 126a may be the same as the thickness T2 of the headrest support 12, and the height W2 of the front insertion hole 126a may be the same as the width W2 of the headrest support 12. Accordingly, the headrest support 12 indicated by dotted lines may be inserted only into the front insertion hole 126a, so that movement in the left and right direction may be prevented by the front insertion hole 126a.

[0058] The fixing handle 124 may be movably arranged on the rear surface of the bracket body 122 in a screw-fastened manner. That is, the headrest support 12 may be fastened and fixed to the bracket body 122 in a state of being inserted into the support-inserted hole 122a by rotating the fixing handle 124 in a forward direction. On the other hand, the fastened state of the headrest support 12 may be released by rotating the fixing handle 124 in a reverse direction.
