Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically a head positioning device for nursing care. Background Technology

[0002] Nursing head positioning devices are assistive devices used in medical or nursing settings to help stabilize or support the position of a patient's head. These devices are typically used in situations requiring head stability or specific postures, such as for stroke patients, paralyzed individuals, or those with neurological disorders, to help maintain the head in the correct position and prevent neck muscle atrophy or deformity.

[0003] Existing head-support devices generally employ a fixed structural design to support the user's neck, lacking necessary adjustment functions. While this rigid support method can maintain the position of the head and neck to some extent, the inability to flexibly adjust the support height and angle according to individual differences results in poor adaptability and comfort. Different users have different neck lengths, thicknesses, physiological curvatures, and required support postures, and the fixed design cannot meet these diverse practical needs, limiting the device's applicability in clinical care or home use. Some users may experience pressure, discomfort, or even impaired blood circulation due to improper support, and caregivers cannot make personalized adjustments according to specific care scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a head-supporting positioning device for nursing care, addressing the problem that existing head-supporting positioning devices, as mentioned in the background section, are mostly fixed structures that cannot adjust the support height and angle, making it difficult to adapt to the neck size and posture requirements of different users. This lack of flexibility can easily lead to discomfort or pressure, affecting comfort and applicability, and failing to meet personalized care requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a head-assisting positioning device for nursing care, comprising a base, a pad fixedly connected to the front side of the base, a padding assembly provided in the inner cavity of the base and the pad, the padding assembly including a threaded rod and a rotating rod, torsion springs installed on the outer surfaces of the left and right sides of the rotating rod, a movable block fixedly connected to the surface of the rotating rod, the top of the movable block extending to the outer side of the top of the pad and fixedly connected to a support plate, and a card seat fixedly connected to both the left and right sides of the base.

[0006] Furthermore, a fixing plate is fixedly connected to the inner cavity of the pad, and one side of the fixing plate is rotatably connected to both ends of the rotating rod.

[0007] Furthermore, a push block is fixedly connected to the surface of the rotating rod, and a guide block is slidably connected to the bottom of the inner cavity of the pad.

[0008] Furthermore, a positioning plate is fixedly connected to the bottom of the inner cavity of the pad, a top rod is fixedly connected to the front side of the guide block, and a push block is fixedly connected to the surface of the rotating rod.

[0009] Furthermore, a spring is fitted onto the surface of the push rod, and the two ends of the spring are respectively fixedly connected to one side of the guide block and the positioning plate. One end of the push rod extends through to the front side of the positioning plate and contacts the surface of the push block.

[0010] Furthermore, a long rod is rotatably connected to the inner cavity of the pad, and a cam that contacts the rear side of the guide block is fixedly connected to the surface of the long rod.

[0011] Furthermore, a worm gear is fixedly connected to the surface of the long rod, and a worm that meshes with the worm gear is rotatably connected to the inner cavity of the pad.

[0012] Furthermore, the surface of the threaded rod is threadedly connected to two threaded blocks arranged symmetrically on the left and right, and the surface of the threaded blocks is slidably connected to the inner cavity of the base. A clamping plate is fixedly connected to the top of the threaded blocks.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: This invention, through the inclusion of a padding assembly, not only enables flexible adjustment of the angle of the neck support plate but also enhances the adaptability and comfort of the support structure. The padding assembly moves synchronously with the support plate in conjunction with the adjustment mechanism, ensuring that it always conforms to the physiological curvature of the neck during angle adjustment, effectively dispersing local pressure and preventing pressure or discomfort caused by prolonged fixation. This also improves the user's comfort experience. Since different users have varying neck lengths, thicknesses, and posture requirements, this adjustable padding design significantly improves the device's versatility, making it suitable for adults, children, and patients with special needs, meeting personalized care requirements. Thus, while achieving stable head positioning, it also ensures natural neck support and comfortable fixation, improving the overall user experience. Attached Figure Description

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A head positioning assist device for nursing care, such as Figures 1-5 As shown, the device includes a base 1, with a pad 2 fixedly connected to the front side of the base 1. A pillow for the user's head is installed on the top of the base 1. A padding assembly 4 is provided in the inner cavity of the base 1 and the pad 2. The padding assembly 4 includes a threaded rod 41 and a rotating rod 45. The threaded rod 41 is rotatably connected to the inner cavity of the base 1. The surface of the threaded rod 41 has two external threads arranged in opposite directions. Torsion springs 48 are installed on the outer surfaces of the left and right sides of the rotating rod 45. A moving block 46 is fixedly connected to the surface of the rotating rod 45. Through cavities are opened on both sides of the top of the pad 2 to facilitate the movement of the moving block 46. The top of the moving block 46 extends to the outer side of the top of the pad 2 and is fixedly connected to a support plate 47.

[0020] like Figures 2-5As shown, the inner side of the support plate 47, where it contacts the user's neck, is fitted with a flexible material such as a sponge pad. The left and right sides of the base 1 are fixedly connected to a mounting bracket 3, which facilitates the user's installation of the base 1 with external objects. A fixing plate 44 is fixedly connected to the inner cavity of the pad 2. One side of the fixing plate 44 is rotatably connected to both ends of the rotating rod 45. A push block 49 is fixedly connected to the surface of the rotating rod 45. A guide block 410 is slidably connected to the bottom of the inner cavity of the pad 2. A positioning plate 411 is fixedly connected to the bottom of the inner cavity of the pad 2. A top rod 417 is fixedly connected to the front side of the guide block 410. A push block 49 is fixedly connected to the surface of the rotating rod 45. A spring 412 is sleeved on the surface of the top rod 417. Both ends of the spring 412 are fixedly connected to one side of the guide block 410 and the positioning plate 411, respectively. One end of the top rod 417 extends through to the front side of the positioning plate 411 and contacts the surface of the push block 49. The end of the top rod 417 that contacts the push block 49 is spherical.

[0021] like Figures 3-5 As shown, a long rod 413 is rotatably connected to the inner cavity of the pad 2. A cam 414 is fixedly connected to the surface of the long rod 413, which contacts the rear side of the guide block 410. A protrusion is fixedly connected to the rear side of the guide block 410, and the protrusion contacts the cam 414. A worm gear 415 is fixedly connected to the surface of the long rod 413. A worm 416 that meshes with the worm gear 415 is rotatably connected to the inner cavity of the pad 2. One end of the worm 416 extends to the outer side of the pad 2 and is fixedly connected to a torsion block that facilitates the user's twisting. Two threaded blocks 42 are threadedly connected to the surface of the threaded rod 41, which are arranged symmetrically on the left and right. The area of ​​the threaded block 42 that contacts the threaded rod 41 is provided with a matching internal thread. The surface of the threaded block 42 is slidably connected to the inner cavity of the base 1. A clamping plate 43 is fixedly connected to the top of the threaded block 42. A flexible material, such as a sponge pad, is installed on the inner side of the clamping plate 43, so that the clamping plate 43 can clamp the user's head and form a buffer area.

[0022] Specifically, twisting the threaded rod 41 causes two threaded blocks 42 to move in opposite directions. The threaded blocks 42 then drive the clamping plate 43 to move, thus positioning and clamping the user's head. Once the head is clamped, the long rod 413 can be further rotated, causing the cam 414 to rotate. The cam 414 pushes the guide block 410 forward, which in turn drives the push rod 417 forward, compressing the spring 412 to store energy. When rotating in the opposite direction, the spring 412 returns to its original position. The push rod 417 pushes the push block 49 to swing around the rotating rod 45, causing the rotating rod 45 to rotate and compress the torsion spring 48. When moving in the opposite direction, the torsion spring 48 returns to its original position. The rotating rod 45 drives the moving block 46 and the support plate 47 to move synchronously, thereby adjusting the angle of the support plate 47. Thus, while positioning and clamping the user's head, the support angle for the neck can be flexibly adjusted, effectively preventing numbness and discomfort in the neck due to prolonged fixation.

[0023] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
