Description

Technical Field

[0001] This utility model relates to the field of turning devices, and in particular to a turning device for cervical spine patients for spinal care. Background Technology

[0002] There are various types of turning devices currently available on the market, generally used for patients with hemiplegia, paraplegia, or limited mobility. If patients maintain one position in bed for extended periods, it can easily lead to complications such as pressure sores, lung infections, and venous thrombosis. Patients with high-level paraplegia have an even higher incidence of pressure sores due to prolonged pressure on specific areas of the body and impaired blood circulation. Therefore, these patients require regular posture adjustments. However, there is a lack of turning devices on the market specifically designed for patients with cervical spondylosis.

[0003] For patients with cervical spondylosis and cervical fractures, nerve root compression and muscle tension make head stability crucial after turning over. However, existing turning devices can only assist patients in turning over. After turning over (from face up to side-turned position, i.e., face to one side), the head angle changes, requiring readjustment of the headrest. During the adjustment of the headrest, the head support angle often changes compared to the original angle before turning over, which can easily aggravate cervical spondylosis. Based on the above situation, a turning device for cervical spondylosis patients for spinal care needs to be designed to solve the above problems. Utility Model Content

[0004] This utility model provides a turning device for cervical spondylosis patients for spinal care. It is equipped with a headrest to lock the angle of the head. When the patient turns over, the body drives the head to turn automatically. After the turning is completed, the angle of head support can be locked to avoid changes in the head support state before and after turning over, which could lead to the aggravation of cervical spondylosis.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] This utility model provides a cervical spine patient turning device for spinal care, including a rectangular frame, a movable board support for supporting the body, and a drive assembly for driving the movable board support to turn over. One end of the rectangular frame is also provided with a U-shaped headrest for supporting the human head. The bottom of the U-shaped headrest is integrally formed and extends downward with a semi-circular rib. A strip-shaped rectangular groove is provided on the rectangular frame. The semi-circular rib and the strip-shaped rectangular groove are in rolling cooperation. A plate brake is also slidably provided inside one end of the rectangular frame. The plate brake extends into the interior of the strip-shaped rectangular groove. A first telescopic rod is fixedly connected to the side of the plate brake away from the strip-shaped rectangular groove. The end of the first telescopic rod away from the plate brake is fixed by a mounting bracket fixedly connected to the rectangular frame.

[0007] Preferably, the U-shaped headrest has side air cushions at both ends, and the side air cushions have fitting holes that hook onto the two ends of the U-shaped headrest. The side air cushions also have an inflatable chamber, and the side of the inflatable chamber corresponding to the side closest to the human head is made of an inflatable material. The upper surface of the U-shaped headrest is also covered with a soft pad.

[0008] Preferably, the rectangular frame has two movable plate supports, which are hinged to the rectangular frame. The rectangular frame has two drive components, each of which drives one movable plate support to move.

[0009] Preferably, when the two movable plate supports are hinged in different directions under the drive of the corresponding drive components, they correspond to the human body being flipped in different directions.

[0010] Preferably, the drive assembly includes two support beams fixed on a rectangular frame, a rotating shaft rotatably connected between the two support beams, a drive handle fixed on the outer surface of the rotating shaft, a drive arm fixed on the outer surface of the rotating shaft, a roller rotatably connected to the end of the drive arm away from the rotating shaft, and a second telescopic rod. One end of the second telescopic rod is hinged to the drive handle, and the other end is hinged to the rectangular frame.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0028] refer to Figures 1-6This utility model provides a structural schematic diagram of a cervical spondylosis patient turning device for spinal care. The main structure is a bed frame that allows cervical spondylosis patients to lie flat. The bed frame is equipped with auxiliary components to assist patients in turning over. Of course, a conventional bed frame can also be used. The main innovation of this utility model is the inclusion of a headrest in the area of ​​the bed frame corresponding to the head support of the cervical spondylosis patient. Compared to traditional headrests, this headrest has the effect of fixing the head and providing support. The main body of the headrest is a U-shaped headrest 11. The concave portion of the U-shaped headrest 11 is used to accommodate the human head and the connected neck portion. The two sides of the U-shaped headrest 11 are pressed against the cheeks of the human body, and the concave portion of the U-shaped headrest 11 provides support for the back of the head, thereby fixing the head support position. The U-shaped headrest 11 has rolling contact with the bed frame. At the bottom of the U-shaped headrest 11... The body has a semi-circular rib 12 extending downwards. A rectangular groove 10 is provided on the bed frame (hereinafter referred to as the rectangular frame 1 of the bed frame with auxiliary turning function). The semi-circular rib is placed in the rectangular groove 10. When the cervical spine patient turns over, the head is turned by the body turning, which releases the angle locking state of the U-shaped headrest 11. The U-shaped headrest 11 rolls inside the rectangular groove 10 (there may be relative sliding during the rolling process, but the relative sliding is very small and can be ignored), thereby realizing the angle adjustment of the U-shaped headrest 11. After turning over, the angle of the U-shaped headrest is locked to keep the head support state unchanged. That is, before and after turning over, the head is not affected by the headrest and can stably support the head, thereby reducing the stress on the cervical spine and causing damage to the cervical spine due to the unstable head support state during or after turning over.

[0029] Specifically, a slide valve 18 is slidably installed at one end of the bed (the rectangular frame 1 of the bed with the auxiliary turning function mentioned below). The slide valve 18 extends into the interior of the strip-shaped rectangular groove 10. A first telescopic rod 20 is fixedly connected to the side of the slide valve away from the strip-shaped rectangular groove 10. The end of the first telescopic rod 20 away from the slide valve is fixed by a mounting bracket 19 fixedly connected to the rectangular frame 1. That is, when the first telescopic rod 20 is shortened, the telescopic rod drives the slide valve 18 to move, disengaging from the side wall of the semi-circular rib 12, so that the U-shaped headrest 11 is in an unlocked state. When the body moves the head, the U-shaped headrest 11 can roll to adjust the angle. After turning over, the first telescopic rod 20 drives the slide valve 18 to move, so that the slide valve 18 presses against the side wall of the semi-circular rib 12, thereby generating friction and locking the U-shaped headrest 11 at the current angle.

[0030] To accommodate people with different head sizes, the U-shaped headrest 11 has side air cushions 14 at both ends. The side air cushions 14 have fitting holes 24 that hook onto the ends of the U-shaped headrest 11. Each side air cushion 14 also has an inflatable chamber 25. The side of the inflatable chamber 25 closest to the head is made of an inflatable material. A soft pad 15 is also laid on the upper surface of the U-shaped headrest 11. Specifically, the fitting holes 24 of the side air cushions 14 can accommodate both ends of the U-shaped headrest 11 (i.e., the two vertical arms 13 in the attached diagram) and are installed... It should have a certain degree of damping, so it is best to use rubber material. The inflatable chamber 25 corresponds to the side near the human head. The expandable material can also be a thin rubber material (thinner than the outer wall of the adapter hole 24), and the surface has a flexible sponge or cloth layer to achieve flexible contact with the side of the face. The upper surface of the U-shaped headrest 11 (i.e. the U-shaped recessed area) is also covered with a soft pad 15. The soft pad 15 can be a sponge, cloth or a flexible combination of both to support the back of the head.

[0031] Furthermore, the inflation chamber 25 can be inflated using an external inflation device, or it can be inflated by installing an air pump 16 on one side of the bed. The air pump 16 inflates the inside of the inflatable chamber 25 through the air inlet pipe 17, causing the inflatable material area to expand and achieve contact with the side of the human face. When both side air cushions 14 are inflated, the human head can be clamped.

[0032] The aforementioned bed frame can be a regular bed frame or a bed frame with an auxiliary turning function. Specifically, the bed frame with the auxiliary turning function consists of a rectangular frame 1, movable board supports 2 for supporting the body, and a drive assembly for driving the movable board supports 2 to turn. The two movable board supports 2 are symmetrically located in the middle of the rectangular frame 1 to support the body. The two movable board supports 2 are hinged to the rectangular frame 1 on the side closest to each other, and each movable board support 2 has an independent drive assembly. By driving the movable board supports 2 to turn around their own hinge axis 5, the body can be turned in different directions. A flexible layer 23 (such as a quilt that is used as a mattress, as long as it is soft enough) can be laid on the two movable board supports 2.

[0033] Specifically, the drive assembly includes two support beams 4 fixed on the rectangular frame 1, a rotating shaft rotatably connected between the two support beams 4, a drive handle 6 fixed on the outer surface of the rotating shaft, a drive arm 8 fixed on the outer surface of the rotating shaft, a roller 9 rotatably connected to the end of the drive arm 8 away from the rotating shaft, and a second telescopic rod 7. One end of the second telescopic rod 7 is hinged to the drive handle 6, and the other end is hinged to the rectangular frame 1. A guide rail 3 is fixedly connected to the lower surface of the movable plate support 2 and cooperates with the roller 9. That is, when the second telescopic rod 7 extends or retracts, the end of the second telescopic rod 7 drives the drive handle 6 to move, and the drive handle 6 drives the rotating shaft to rotate. The rotating shaft drives the drive arm 8 to lift the movable plate support 2, causing it to flip along the hinge axis 5. The lifting end of the drive arm 8 (i.e., the end away from the rotating shaft) is provided with a roller 9. A guide rail 3 is fixed on the lower surface of the movable plate support 2. The roller 9 rolls between the guide rail 3, thereby reducing friction and noise.

[0034] Furthermore, the support leg 22 at the bottom of the rectangular frame 1 should be configured as an adjustable height support leg 22 so that patients on beds of different heights can be moved horizontally onto the bed. Of course, it is preferable that the support leg 22 and the rectangular frame 1 are detachable, so that the support leg 22 can be removed and the rectangular frame 1 can be placed directly above the bed for use.

[0035] Specifically, in order to enable patients to control their turning themselves, the controller 21 can be adapted to the cervical spine patient turning device described above, i.e., as follows: Figure 7 As shown, the controller 21 controls the patient's turning angle and the locking and unlocking of the headrest by controlling the operation of the first telescopic rod 20 and the second telescopic rod 7. Specifically, the controller 21 with buttons can control the operation of the first telescopic rod 20. The buttons have buttons to control the operation of the first telescopic rod 20 of the two drive components (if there are two drive components, there are four buttons, which correspond to controlling the extension and retraction of the two first telescopic rods 20 respectively). When any button is pressed, the controller 21 first controls the second telescopic rod 7 to retract, so that the headrest is in the unlocked state. When all buttons are in the untriggered state, the controller 21 controls the second telescopic rod 7 to extend, so that the headrest is in the locked state.

[0036] Furthermore, such as Figure 2 and Figure 8 As shown, in order to ensure the safety of patients, an angle sensor 26 is also provided on the rotating shaft to detect its rotation angle. When the angle sensor 26 detects that the current rotation angle is too large (exceeding the preset range value), it locks the current state to prevent people from continuously touching the button, causing the rotation angle to be too large and affecting the safety of patients.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
