[0057] Please refer to Figure 1-15 In this invention, a technical solution is provided: a body position changing device for nursing, including a bed body 1 and a back plate 2 for pushing the back of a patient. One end of the back plate 2 is rotatably connected to the middle of the top surface of the bed body 1, and the rotation center line is parallel to the top surface of the bed body 1. On both sides of the top surface of the bed body 1, side plates 3 are provided. On the opposite sides of the two side plates 3, they are rotatably connected to the top surface of the bed body 1, and the rotation center line is perpendicular to the rotation center line of the back plate 2 on the bed body 1;

[0058] Between the back plate 2 and the bed body 1, a first adjusting part is provided for driving the back plate 2 to rotate on the bed body 1;

[0059] Between the side plate 3 and the bed body 1, a second adjusting part is provided for driving the side plate 3 to rotate on the bed body 1.

[0060] In this solution: A back plate 2 is provided at one end of the head of the bed on the top surface of the bed body 1. The first adjusting part is used to drive the back plate 2 to rotate on the bed body 1, pushing and lifting the back of the patient, so that the patient changes from a lying state to a semi - lying or sitting state; Side plates 3 are provided on both sides of the top surface of the bed body 1. The second adjusting part is used to drive the side plates 3 to rotate on the bed body 1, lifting and supporting the trunk of the patient, so that the patient changes from a lying state to a side - lying state or turns over to a prone state, achieving the purpose of assisting the patient in changing body positions. This body position changing device can assist the patient to freely switch between lying, semi - lying, sitting, side - lying, and prone positions, and has high practicability.

[0061] When the bottom surfaces of the back plate and the side plates are both in contact with the top surface of the bed body, it is the first use state of this device. As shown in Figure 1 、 Figure 2 、 Figure 9 The patient can lie on this device; When the bottom surface of the side plate is in contact with the top surface of the bed body and the back plate is in an inclined state, it is the second use state of this device. As shown in Figure 10 、 Figure 11 、 Figure 12 The patient can semi - lie or sit on this device; When the bottom surface of the back plate is in contact with the top surface of the bed body and the side plates are in an inclined state, it is the third use state of this device. As shown in Figure 13 、 Figure 14 、 Figure 15 This device can assist the patient to turn over or support the patient's body, so that the patient maintains a side - lying state.

[0062] In this embodiment: The side plate 3 includes a rotating bar 31 provided at the end of the back plate 2 facing the foot of the bed of the bed body 1 and a connecting bar 32 perpendicular to the rotating bar 31. One end of the rotating bar 31 is fixedly connected to the middle of the connecting bar 32, and the other end is rotatably connected to the middle of the top surface of the bed body 1;

[0063] Both ends of the connecting bar 32 extend towards the head and foot ends of the bed body 1 respectively.

[0064] In this solution: the side plate 3 and the back plate 2 have the same thickness. When the bottom surface of the side plate 3 and the bottom surface of the back plate 2 are both in contact with the top surface of the bed body 1, the side plate 3 and the back plate 2 are spliced to form a complete plate-like structure to cover the top surface of the bed body 1; a hinge seat 14 is fixedly connected to the top surface of the bed body 1. One end of the rotating bar 31 is rotatably connected to the hinge seat 14, and when the bottom surface of the rotating bar 31 is in contact with the top surface of the bed body 1, the top end of the hinge seat 14 is lower than the top surface of the rotating bar 31, making the plate-like structure formed by the side plate 3 and the back plate 2 smoother.

[0065] The rotating bar 31 is arranged at one end of the back plate 2 facing the bed tail of the bed body 1, so that one end of the rotating bar 31 facing away from the connecting bar 32 is close to the middle of the width direction of the top surface of the bed body 1, and the rotation center line of the side plate 3 is close to the middle of the width direction of the top surface of the bed body 1. Since patients usually lie in the middle of the width direction of the bed body 1, the side plate 3 is easy to lift the patient's torso, providing convenience for turning the patient over.

[0066] In this embodiment: a plurality of extension rods 33 are arranged on both opposite sides of the two connecting bars 32, and the plurality of extension rods 33 are evenly arranged along the length direction of the connecting bars 32;

[0067] One end of the extension rod 33 is fixedly connected to the corresponding connecting bar 32, and the other end extends along the length direction of the corresponding rotating bar 31;

[0068] Notches 21 corresponding to the plurality of extension rods 33 on the two connecting bars 32 are formed on both sides of the back plate 2, and the extension rods 33 can be inserted into the corresponding notches 21.

[0069] In this solution: by arranging the extension rods 33 on the connecting bars 32, the covered area of the side plate 3 is increased, so as to facilitate the side plate 3 to lift the patient's body. At the same time, notches 21 for receiving the extension rods 33 are formed on the back plate 2, so that the covered area of the back plate 2 remains unchanged, reducing the influence on the pushing work of the back plate 2.

[0070] In this embodiment: two convex blocks 11 arranged in the width direction of the bed body 1 are fixedly connected to the middle of the top surface of the bed body 1, and a rotating shaft 22 is commonly connected in series with the two convex blocks 11 and is rotationally matched;

[0071] The middle of the rotating shaft 22 is fixedly connected to one end of the back plate 2 facing the bed tail of the bed body 1.

[0072] In this solution: when the bottom surface of the back plate 2 is in contact with the top surface of the bed body 1, the top end of the convex block 11 is lower than the top surface of the back plate 2, making the patient more comfortable when lying flat on this device.

[0073] In this embodiment: two limit pins 23 corresponding to the two side plates 3 are arranged on the two convex blocks 11. One end of the limit pin 23 is slidably connected to the convex block 11 along the length direction of the limit pin 23, and the other end extends toward one side of the corresponding side plate 3 along the sliding direction;

[0074] On both opposite sides of the two side plates 3, limiting holes 311 are provided. The two limiting holes 311 are arranged in one-to-one correspondence with the two limiting pins 23. When the side plates 3 are parallel to the top surface of the bed body 1, the limiting pins 23 can be inserted into the corresponding limiting holes 311.

[0075] In this solution: The limiting hole 311 is arranged on the end surface of the rotating bar 31 facing away from the connecting bar 32, and the limiting hole 311 extends along the length direction of the rotating bar 31. When the device is in state two (as shown in Figure 10-12 ), the opening of the limiting hole 311 faces the limiting pin 23, so that the limiting pin 23 can slide on the convex block 11 and be inserted into the limiting hole 311, restricting the rotation of the rotating bar 31 on the hinge seat 14, thereby restricting the rotation of the side plate 3 on the bed body 1, and only allowing the back plate 2 to rotate on the bed body 1, reducing the influence of the rotation of the side plate 3 on the rotation of the back plate 2.

[0076] In this embodiment: One end of the limiting pin 23 facing away from the corresponding side plate 3 is inserted into the corresponding convex block 11, and the limiting pin 23 and the corresponding convex block 11 are in single-degree-of-freedom sliding fit along the length direction of the limiting pin 23;

[0077] External threads are provided at both ends of the rotating shaft 22. The two limiting pins 23 are respectively sleeved outside both ends of the rotating shaft 22, and the limiting pins 23 and the rotating shaft 22 are connected by thread fit.

[0078] In this solution: The limiting pin 23 is octagonal prism-shaped. A receiving hole 111 adapted to the outer shape of the limiting pin 23 is provided on the side surface of the convex block 11 facing the corresponding side plate 3. The limiting pin 23 is inserted into the receiving hole 111 to restrict the free rotation of the limiting pin 23, so that the limiting pin 23 can only slide in a single degree of freedom along its own length direction. By thread-fitting the limiting pin 23 with the rotating shaft 22, when the rotating shaft 22 rotates, the external thread on the rotating shaft 22 applies an external force along the length direction of the limiting pin 23 to the limiting pin 23, causing the limiting pin 23 to slide on the convex block 11.

[0079] During use, when the device is in state one (as shown in Figure 1 , Figure 2 , Figure 9 ), the opening of the limiting hole 311 faces the corresponding limiting pin 23. When the back plate 2 is in contact with the top surface of the bed body 1, the limiting pin 23 is completely embedded in the receiving hole 111. When it is necessary to adjust the device to state two (as shown in Figure 10-12 ), the back plate 2 is driven to rotate forward on the bed body 1 through the first adjusting part, so that the rotating shaft 22 rotates forward on the convex block 11. The rotating shaft 22 pushes the limiting pin 23 to slide out of the receiving hole 111 and at the same time insert into the corresponding limiting hole 311, restricting the rotation of the side plate 3 on the bed body 1.

[0080] When the patient needs to be adjusted to the prone position, the device is adjusted from State 1 to State 3 (as Figure 13-15 shown), the second adjustment part is used to drive the side plate 3 to rotate forward on the window body, so that the opening of the limit hole 311 on the rotating bar 31 is misaligned with the limit pin 23, and the end face of the limit pin 23 facing one end of the corresponding rotating bar 31 is in contact with the end face (semicircular curved surface) of the rotating bar 31 provided with the limit hole 311, hindering the limit pin 23 from sliding towards the corresponding side plate 3 direction, so as to limit the positive rotation of the rotating shaft 22, that is, to limit the rotation of the back plate 2 on the bed body 1.

[0081] Therefore, when the device is in State 2, the limit pin 23 automatically inserts into the limit hole 311 to lock the side plate 3 and limit the rotation of the side plate 3 on the bed body 1; when the device is in State 2, the limit pin 23 abuts against the rotating bar 31 to lock the back plate 2 and limit the rotation of the back plate 2 on the bed body 1, preventing the side plate 3 and the back plate 2 from rotating simultaneously and interfering with each other, which affects the body position transformation work.

[0082] In this embodiment: a first chute 12 extending in the length direction of the bed body 1 is opened in the middle of the top surface of the bed body 1, and the first adjustment part includes a first slider 41, a first screw rod 42 and a first support rod 43 embedded in the first chute 12;

[0083] The first slider 41 and the first chute 12 are slidably matched along the length direction of the first chute 12, the first slider 41 is sleeved outside the first screw rod 42 and is connected with the first screw rod 42 through a threaded fit;

[0084] One end of the first screw rod 42 is inserted into the end wall of the first chute 12 facing the head of the bed body 1 and is rotationally matched, and the other end penetrates through the end wall of the first chute 12 facing the tail of the bed body 1 and protrudes outside the bed body 1;

[0085] One end of the first support rod 43 is hinged to the top end of the first slider 41, and the other end is hinged to the middle of the bottom surface of the back plate 2, and the rotation center line is parallel to the rotation center line of the back plate 2 on the bed body 1.

[0086] In this solution: the first screw rod 42, the first support rod 43 and the back plate 2 form a triangular structure. The whole first support rod 43 is used as the first side, the section between the hinge point of the first support rod 43 and the back plate 2 and the hinge point of the back plate 2 and the bed body 1 is the second side, and the section between the hinge point of the back plate 2 and the bed body 1 on the first screw rod 42 and the first slider 41 is the third side; among them, the lengths of the first side and the second side are fixed, and by moving the first slider 41 on the first screw rod 42, the length of the third side is changed, so that the included angle between the second side and the third side is changed, so as to adjust the inclination angle of the back plate 2.

[0087] In this embodiment: On both sides of the top surface of the bed body 1, two second sliding grooves 13 corresponding to the two side plates 3 are provided. The second sliding grooves 13 extend in the length direction of the bed body 1. The second adjusting part includes a second slider 51, a second lead screw 52, and a second support rod 53 that are embedded in the second sliding grooves 13;

[0088] The second slider 51 and the second sliding groove 13 are slidably matched along the length direction of the second sliding groove 13. The second slider 51 is sleeved outside the second lead screw 52 and is connected to the second lead screw 52 through a threaded fit;

[0089] One end of the second lead screw 52 is inserted into and rotatably matched with the end wall of the second sliding groove 13 facing the head of the bed body 1, and the other end penetrates through the end wall of the second sliding groove 13 facing the tail of the bed body 1 and protrudes outside the bed body 1;

[0090] One end of the second support rod 53 is hinged to the top end of the second slider 51, and the rotation center line is parallel to the rotation center line of the back plate 2 on the bed body 1. The other end is connected to the middle part of the bottom surface of the corresponding side plate 3.

[0091] In this embodiment: Two second sliders 51 are provided in the second sliding groove 13, and the two second sliders 51 are respectively located at both ends of the second sliding groove 13;

[0092] Second support rods 53 are hinged to both of the second sliders 51. The ends of the two second support rods 53 facing away from the corresponding second sliders 51 are jointly hinged to a connecting block 54, and the rotation center line is parallel to the rotation center line of the second support rod 53 on the corresponding second slider 51;

[0093] The connecting block 54 is slidably connected to the bottom surface of the side plate 3 in the width direction of the side plate 3.

[0094] In this solution: The first lead screw 42 and the second lead screw 52 are centrally arranged at one end of the tail of the bed body 1 to facilitate centralized control of the rotation of the back plate 2 and the side plate 3. An isosceles triangle structure is formed by the two second support rods 53 and the second lead screw 52. The two second support plates serve as the two waists of the isosceles triangle structure, and the section between the two second sliders 51 on the second lead screw 52 is the base. Among them, the lengths of the two waists are fixed. By moving the two second sliders 51 on the second lead screw 52, the length of the base is changed, so that the included angle between the two waists is changed, to adjust the height of the connecting block 54, so that the connecting block 54 slides on the side plate 3 in the width direction of the side plate 3, to drive the side plate 3 to rotate on the bed body 1.

[0095] In this embodiment: On the side surface of the side plate 3 facing away from the bed body 1, a sliding hole 312 extending in the width direction of the side plate 3 is provided, and a sliding strip 55 is slidably matched in the sliding hole 312;

[0096] One end of the sliding bar 55 protrudes from the opening of the sliding hole 312 and is hinged to the connecting block 54, and the rotation center line is parallel to the rotation center line of the side plate 3 on the bed body 1.

[0097] In this solution: The sliding hole 312 is arranged on the end face of the rotating bar 31 facing away from the bed body 1. A triangular pyramid structure is formed by the two second support rods 53, the sliding bar 55, the rotating bar 31 and the top surface of the bed body 1. The top surface of the bed body 1 serves as the bottom surface of this triangular pyramid structure, the two support rods serve as two hypotenuses, the telescopic rod structure formed by the sliding bar 55 and the rotating bar 31 serves as the third hypotenuse, and the connecting block 54 serves as the vertex of this triangular prism structure.

[0098] During use, when it is necessary to assist the patient to turn over, when the second lead screw 52 is rotated forward, the two second sliders 51 move towards each other and gather together. The second support rod 53 rotates on the slider to increase the angle with the second lead screw 52. The two second support rods 53 rotate on the connecting block 54 at the same time, pushing the connecting block 54 to move upward and increasing the height of the connecting block 54; at the same time, the connecting block 54 drives the sliding bar 55 to slide out of the sliding hole 312, increasing the overall length of the sliding bar 55 and the rotating bar 31, so that the sliding bar 55 drives the rotating bar 31 to rotate forward on the bed body 1, increasing the angle between the side plate 3 and the top surface of the bed body 1.
