Description

Technical Field

[0001] This utility model relates to the field of medical assistive devices, and in particular to an adjustable head tilt support. Background Technology

[0002] In ophthalmological treatment, the most suitable position for patients is to lie on their backs for easy drug administration. However, for patients such as children, they will frequently turn their heads to avoid the medication, which reduces efficiency.

[0003] Furthermore, some clinics do not have examination beds, so patients can only maintain a supine position by leaning back in a high-backed chair with their neck against the top of the chair back. This position is very uncomfortable for patients and their heads will also move. Utility Model Content

[0004] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of this invention is to provide a bracket that can be placed on a chair back for fixing the head when tilting it back.

[0005] To achieve the above objectives, embodiments of this utility model provide an adjustable head tilt support, comprising:

[0006] Support: Detachably connected to the chair back, the support has a vertically movable support component, and the support component has a bracket;

[0007] Bracket: Includes a tray, which is recessed downward to form a space for accommodating the patient's neck and back of the head; the tray has swingable wings on both sides, which are connected together by straps; the tray, wings and straps together restrain the patient's head within the space of the bracket.

[0008] According to an embodiment of the present invention, an adjustable head tilt support is provided. Since the support is fixed to the back of the chair, and the bracket restrains the patient's head, the height of the bracket can be adjusted up and down on the support, so that the patient can maintain a head tilted back in the chair and the head will not turn, thereby improving the accuracy of eye medication.

[0009] In addition, the adjustable head tilt support proposed in the above embodiments of this utility model may also have the following additional technical features:

[0010] Optionally, the support member and the bracket are hinged by a movable joint, which can swing and rotate.

[0011] Optionally, a through hole is formed radially along the support member, and a movable pin passes through the bracket and the through hole to restrict the relative movement of the support member and the bracket.

[0012] Optionally, the tray may also include support points made of a flexible material.

[0013] Optionally, the support includes a clamping plate and a clamping groove, with the clamping plate embedded in the clamping groove, and the distance between the clamping plate and the clamping groove adjusted by fasteners.

[0014] Furthermore, the surfaces of the clamping plate and the clamping groove opposite each other are provided with interlocking anti-slip teeth. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] Because the bracket is fixed to the back of the chair, and the support restrains the patient's head, the height of the support can be adjusted up and down on the bracket, so that the patient can keep their head tilted back in the chair and their head will not turn, thus improving the accuracy of eye medication.

[0024] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Figures 1 to 4 An adjustable head tilt support according to an embodiment of the present utility model includes:

[0027] Support 1: Detachably connected to the backrest, the support 1 is provided with a support member 11 that moves up and down, and a bracket 2 is provided on the support member 11; when in use, the support 1 is fixed to the backrest, turning an ordinary backrest chair into a chair with a headrest, and the support member 11 can be adjusted. When the bracket 2 is fixed to the patient, it can conform to the patient's ergonomics.

[0028] Specifically, the support 11 and the bracket 2 are hinged by a movable joint 12, which can swing and rotate to achieve more adjustment functions. The movable joint 12 can be tightened or loosened by hand-tightening bolts.

[0029] The vertical movement of the support member 11 can be adjusted by forming a through hole 111 along the radial direction of the support member 11, and a movable pin 112 passing through the bracket and the through hole 111 to restrict the relative movement of the support member 11 and the bracket 2. The vertical adjustment of the support member 11 is rarely used, and it must be ensured that it will not move during use. Therefore, this solution is reliable and convenient for adjustment.

[0030] Support 2 includes a tray 21, which is recessed to form a space for accommodating the patient's neck and back of the head. The tray 21 has swingable side wings 22, which are connected together by straps 23. The tray 21, side wings 22, and straps 23 together restrain the patient's head within the space of the support 2. The areas of the tray 21 and side wings 22 that contact the head can be provided with silicone anti-slip surfaces. Specifically, the tray 21 also has support points 211 made of elastic material to better support the back of the head. The straps 23 are adjustable in length to fit different head circumferences.

[0031] In some embodiments, the support 1 includes a clamping plate 13 and a clamping groove 14, with the clamping plate 13 embedded in the clamping groove 14. The distance between the clamping plate 13 and the clamping groove 14 is adjusted by fasteners. Furthermore, the opposing surfaces of the clamping plate 13 and the clamping groove 14 are provided with interlocking anti-slip teeth. This embodiment can be easily clamped onto common backrest chairs and is easy to assemble and disassemble.

[0032] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
