Description

Technical Field

[0001] This invention relates to the field of healthcare technology, and more specifically, to a rotating mattress. Background Technology

[0002] In hospital nursing care, nursing beds are required. Existing nursing beds are relatively advanced, and the patient's position can be changed by rotating the bed board to facilitate the patient getting out of bed, which greatly facilitates the nursing work of medical staff and saves their physical strength. However, the current rotating device of the nursing bed requires medical staff to push it by hand when rotating, which is difficult to control the force, and the rotation is not stable enough, which is not conducive to the patient's health and safety. In addition, the angle is difficult to control.

[0003] The existing electric nursing beds with adjustable rotating devices are prone to generating impacts when adjusted, causing discomfort to the patient and affecting the patient's comfort during use. In addition, the existing rotating devices rotate the nursing bed with a large range of motion during rotation, which is very easy to bump into things in the narrow space of the ward. Summary of the Invention

[0004] In view of this, in order to solve the problem that the existing rotating devices cause large amplitude of movement of the rotating nursing bed during rotation, the present invention proposes a rotating mattress, which includes an upper frame 1 and a lower frame 12. The rotating device 16 is provided between the upper frame 1 and the lower frame 12. The upper end of the rotating device 16 is connected to the lower part of the upper frame 1, and the lower end of the rotating device 16 is connected to one end of a third motor 20. The other end of the third motor 20 is connected to the lower frame 12. The lower frame 12 is connected to the upper end of the rotating device 16 via a connecting rod 21. While the third motor 20 pushes the rotating device 16 to move the upper frame 1 back and forth, the tension of the connecting rod 21 causes the rotating device 16 to rotate the upper frame 1. Therefore, the upper frame 1 performs a rotating and forward linear movement, saving rotation space and improving patient comfort.

[0005] A rotating mattress includes an upper frame 1 and a lower frame 12, characterized in that a rotating device 16 is provided between the upper frame 1 and the lower frame 12, the upper end of the rotating device 16 is connected to the lower part of the upper frame 1, the lower end of the rotating device 16 is connected to one end of a third motor 20, the other end of the third motor 20 is connected to the lower frame 12, and the lower frame 12 is connected to the upper end of the rotating device 16 through a connecting rod 21.

[0006] In some embodiments, the lower frame 12 is provided with a slide rail 13 corresponding to the mounting part of the rotating device 16, and the lower end of the rotating device 16 is provided with a slider 14 that matches and is connected to the slide rail 13. The slider 14 is slidably connected to the slide rail 13, so that the rotating device 16 slides on the slide rail 13, which facilitates the rotating device 16 to make linear motion.

[0007] In some embodiments, the lower frame 12 is provided with an upwardly bent fulcrum 15, the free end of which is connected to one end of the connecting rod 21, so that the connecting rod 21 is parallel to the upper end of the rotating device 16, thereby reducing the pulling resistance of the connecting rod 21.

[0008] Furthermore, the end of the connecting rod 21 away from the fulcrum 15 is connected to a corner of the upper end of the rotating device 16.

[0009] Furthermore, when the upper frame 1 and the lower frame 12 are parallel, the end of the connecting rod 21 away from the fulcrum 15 is connected to the corner of the upper end of the rotating device 16 that is close to the connecting rod 21 and away from the fulcrum 15, which facilitates the rotation of the rotating device 16.

[0010] Furthermore, the circle formed at the connection between the connecting rod 21 and the rotating device 16 always intersects with the circle formed with the fulcrum 15 as the center and the connecting rod 21 as the radius. The point of intersection is the connection between the connecting rod 21 and the rotating device 16.

[0011] In some embodiments, the rotating device 16 is provided with connecting holes 17 at each of its four corners. The connecting holes 17 may be one of the following shapes: waist-shaped, square, or round.

[0012] Furthermore, the upper frame 1 and the rotating device 16 are connected by a connector passing through the connecting hole 17, and the connection point between the connecting rod 21 and the rotating device 16 is one of the connecting holes 17.

[0013] In some embodiments, the rotating device 16 includes an upper disk 18 and a lower disk 19, which are connected by bearings.

[0014] Furthermore, the lower disk 19 is connected to the third motor 20, which performs linear motion, while the upper disk 18 is connected to the connecting rod 21, which performs rotational motion.

[0015] In some embodiments, the upper frame 1 includes a back frame 2, a seat frame 3, a thigh frame 4, and a calf frame 5, which are hinged together in sequence from left to right.

[0016] Furthermore, the lower part of the back frame 2 is provided with a back linkage mechanism 6, and the lower part of the calf frame 5 is provided with a calf lifting device 9 for lifting the back and calf.

[0017] Furthermore, the back linkage mechanism 6 includes a first motor 7 and a back linkage rod 8. One end of the first motor 7 is connected to the seat frame 3, and the other end is connected to the back linkage rod 8. The first motor 7 drives the back linkage rod 8 to move, thereby driving the back frame 2 to rise and fall.

[0018] Furthermore, the lower leg lifting device 9 includes a second motor 10 and a lower leg support rod 11. One end of the second motor 10 is connected to the seat frame 3, and the other end is connected to the lower leg support rod 11. The lower leg support rod 11 is moved by the second motor 10, thereby driving the lower leg frame to rise and fall.

[0019] The beneficial effects of the present invention: The present invention proposes a rotating mattress, which includes an upper frame 1 and a lower frame 12. The rotating device 16 is provided between the upper frame 1 and the lower frame 12. The upper end of the rotating device 16 is connected to the lower part of the upper frame 1, and the lower end of the rotating device 16 is connected to one end of a third motor 20. The other end of the third motor 20 is connected to the lower frame 12. The lower frame 12 is connected to the upper end of the rotating device 16 via a connecting rod 21. While the third motor 20 pushes the rotating device 16 to move the upper frame 1 back and forth, the pulling force of the connecting rod 21 causes the rotating device 16 to rotate the upper frame 1. Therefore, the upper frame 1 rotates and moves forward in a linear motion, saving rotation space and improving patient comfort. Attached Figure Description

The lower disc 19 has a slider 14 that matches and connects to the slide rail 13. The slider 14 is slidably connected to the slide rail 13, thereby allowing the rotating device 16 to rotate. The slide rail 13 allows the rotating device 16 to move linearly. The lower frame 12 has an upwardly bent fulcrum 15. When the upper frame 1 and the lower frame 12 are parallel, the end of the connecting rod 21 away from the fulcrum 15 is connected to the corner of the upper end of the rotating device 16 that is close to the connecting rod 21 and away from the fulcrum 15. This facilitates the rotation of the rotating device 16 and makes the connecting rod 21 parallel to the upper end of the rotating device 16, reducing the pulling resistance of the connecting rod 21. The circle formed by the connection between the connecting rod 21 and the rotating device 16 always intersects the circle formed with the fulcrum 15 as the center and the connecting rod 21 as the radius. The intersection point is the connection between the connecting rod 21 and the rotating device 16.
