Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an adjustable and fixed headrest for radiotherapy positioning. Background Technology
[0002] Patients with kyphosis face challenges in head fixation during radiotherapy because their neck tilt angle is greater than that of ordinary people, and conventional headrests cannot accommodate this curvature. Using only a thickened pad can compress the patient's shoulders, leading to inaccurate positioning or discomfort. Therefore, a fixation device that can simultaneously adjust height and angle is needed to reduce pressure on the shoulders and thus provide a comfortable fit for these patients. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies that cannot simultaneously adjust height and angle, and to propose an adjustable and fixed headrest for radiotherapy positioning.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] The radiotherapy positioning adjustable headrest includes an upper pillow and a lower pillow located below it;
[0006] The first inclined panel is fixedly connected to the bottom of the upper cushion.
[0007] The second inclined panel is fixedly connected to the top of the lower cushion.
[0008] A third inclined panel is located between the first and second inclined panels. The inclined surfaces of the third and second inclined panels are respectively provided with a third T-slot and a second T-slot. The inner walls of both sides of the third T-slot are provided with third side holes, and the inner walls of both sides of the second T-slot are provided with second side holes. A third limiting block is fixedly connected to the bottom wall of the third T-slot, and a second limiting block is fixedly connected to the bottom wall of the second T-slot. A third connecting rod is fixedly connected to the plane of the third inclined panel, and a third T-block is fixedly connected to the bottom end of the third connecting rod. A first connecting rod is fixedly connected to the plane of the first inclined panel, and a first T-block is fixedly connected to the bottom end of the first connecting rod.
[0009] Specifically, by inserting the No. 1 T-block into the No. 3 side hole and moving it laterally, it is locked to the side of the No. 3 limiting block, or by inserting the No. 3 T-block into the No. 2 side hole and locking it to the side of the No. 2 limiting block, the inclined panel can be quickly installed and its height and angle can be adjusted synchronously to fit the cervical curvature of hunchback patients.
[0010] In one possible design, a pillowcase is also included, which covers the upper cushion, the first inclined panel, the third inclined panel, the second inclined panel, and the lower cushion.
[0011] In one possible design, the pillowcase has an opening on one side, and a zipper is provided at the opening.
[0012] In one possible design, the top of the upper cushion is provided with a groove.
[0013] In one possible design, the grooved area is provided with silicone anti-slip texture.
[0014] In one possible design, the pillowcase has an elastic section in the middle, which is made of medical-grade silicone film to conform to the outer contour of different beveled panel combinations.
[0015] In this application, when it is necessary to increase the height of the headrest by a single device, first insert the No. 1 T-shaped block at the bottom of the No. 1 inclined panel into the No. 3 T-shaped groove through the No. 3 side hole, move it laterally and press it down to lock it into the side of the No. 3 limiting block. At this time, the installation of one No. 3 inclined panel can be completed. Then, the other No. 3 inclined panel can be installed in reverse at the bottom of the No. 3 inclined panel using the same method. Finally, the lower pad pillow with the No. 2 inclined panel can be installed using the same method. Then, the pillowcase can be put on the assembled headrest. If it is necessary to further increase the height, repeat the method to install the double-layer No. 3 inclined panels in the middle position.
[0016] If you need to adjust the angle while increasing the height, you can simply install a single No. 3 slanted panel, or add a double layer of No. 3 slanted panels after installing a single layer of No. 3 slanted panels.
[0017] In this utility model, the radiotherapy positioning adjustable and fixed headrest, through the plug-in connection of T-slot and T-block, can achieve quick installation between the inclined panels, thereby facilitating actual assembly and use;
[0018] In this invention, the radiotherapy positioning adjustable fixed headrest can be adjusted in height or angle via a slanted panel, thereby solving the problem that the original fixed angle and height could not meet the needs of different individual patients.
[0019] In this invention, the angle can be adjusted and the height can be adjusted simultaneously, thus better adapting to patients with kyphosis, reducing the pressure on their cervical spine, and greatly increasing the adaptability. Attached Figure Description
