As shown in fig. 1 and 2, the present invention relates to a nursing bed including a bed body. The bed body is provided with a bed board component 2, and the bed board component 2 comprises a front bed board 21, a middle bed board 22 and a rear bed board 23.

As shown in fig. 1 and 3, the bed body includes two front support legs 11 and two rear support legs 12, which are vertically disposed, the two front support legs 11 are respectively located at the left and right sides of the front of the bed plate assembly 2, and the two rear support legs 12 are respectively located at the left and right sides of the rear of the bed plate assembly 2. The bed body further comprises a left support rod 13 and a right support rod 14 which are horizontally arranged in the front-back direction, the left support rod 13 is connected with the front support leg 11 and the rear support leg 12 which are positioned on the left side, and the right support rod 14 is connected with the front support leg 11 and the rear support leg 12 which are positioned on the right side. The bed body also comprises a front supporting rod 15 and a rear supporting rod which are horizontally arranged in the left-right direction, the front supporting rod 15 is connected with the two front supporting legs 11, and the rear supporting rod is connected with the two rear supporting legs 12.

As shown in fig. 2, each of the front bed plate 21 and the middle bed plate 22 includes a plurality of long strips 20 horizontally placed in front and back, the plurality of long strips 20 of the front bed plate 21 and the middle bed plate 22 are respectively arranged in parallel in the left-right direction, and two long strips 20 adjacent to each other in the left-right direction are hinged to each other. Furthermore, in order to facilitate the defecation of the patient, the middle of the middle bed plate 22 is provided with a rectangular through hole 221. The rectangular through hole 221 crosses the plurality of elongated plates 20 from left to right, and the plurality of elongated plates 20 are provided on both left and right sides of the rectangular through hole 221.

As shown in fig. 1 and 3, the long lath 20 at the leftmost side of the front bedplate 21 and the long lath 20 at the leftmost side of the middle bedplate 22 are both connected to the bed body through a first power device, and the long lath 20 at the rightmost side of the front bedplate 21 and the long lath 20 at the rightmost side of the middle bedplate 22 are both connected to the bed body through a second power device. The first power device and the second power device are both electrically connected with the controller. The first power device can lift the front bed board 21 and the middle bed board 22 from the left side edges of the front bed board 21 and the middle bed board 22 to the upper right, and the second power device can lift the front bed board 21 and the middle bed board 22 from the right side edges of the front bed board 21 and the middle bed board 22 to the upper left.

Specifically, the first power device includes two first hydraulic cylinders 31 vertically arranged and electrically connected to the controller, the two first hydraulic cylinders 31 are fixedly connected through a fixing rod 35, and the two first hydraulic cylinders 31 are respectively arranged below the front bed plate 21 and the middle bed plate 22. The upper end of the first hydraulic cylinder 31 is hinged with the bottom of the strip plate 20 connected with the first power device, and the lower end is hinged with the left support rod 13. The second power device comprises two second hydraulic cylinders 32 which are vertically arranged and electrically connected with the controller, the two second hydraulic cylinders 32 are fixedly connected through a fixing rod 35, and the two second hydraulic cylinders 32 are respectively arranged below the front bed plate 21 and the middle bed plate 22. The upper end of the second hydraulic cylinder 32 is hinged with the bottom of the strip plate 20 connected with the second power device, and the lower end is hinged with the right support rod 14. In this embodiment, the first hydraulic cylinder 31 and the second hydraulic cylinder 32 below the front bed plate 21 are arranged in bilateral symmetry, and the first hydraulic cylinder 31 and the second hydraulic cylinder 32 below the middle bed plate 22 are arranged in bilateral symmetry; the fixing rods 35 connecting the two first hydraulic cylinders 31 and the fixing rods 35 connecting the two second hydraulic cylinders 32 are symmetrically arranged at the left and right sides of the bed plate assembly 2. Of course, the first hydraulic cylinder 31 and the second hydraulic cylinder 32 may be provided with one or more than two cylinders. However, in order to ensure that the left and right sides of the front bed plate 21 and the middle bed plate 22 can be stably lifted up to the right and left, respectively, and to simplify the structure of the present invention, it is preferable to provide two first hydraulic cylinders 31 and two second hydraulic cylinders 32, respectively.

In order to stabilize the structure of the invention, as shown in fig. 1, a front supporting plate 25 which is horizontally arranged and clings to the front bed plate 21 is arranged below the front bed plate 21, so that the front bed plate 21 can be prevented from moving downwards from the horizontal position; a middle bearing plate 26 which is horizontally arranged and is tightly attached to the middle bed plate 22 is arranged below the middle bed plate 22, so that the middle bed plate 22 can be prevented from moving downwards from the horizontal position. The rear end of the front supporting plate 25 is hinged with the front end of the middle supporting plate 26. In addition, the front support plate 25 and the middle support plate 26 are provided with first notches at left sides thereof for preventing the first hydraulic cylinder 31 from being hindered from moving in an extension/contraction manner, and the front support plate 25 and the middle support plate 26 are provided with first notches at right sides thereof for preventing the second hydraulic cylinder 32 from being hindered from moving in an extension/contraction manner. The arrangement of the first gap ensures that the structure of the invention is reasonable, and the first hydraulic cylinder 31 and the second hydraulic cylinder 32 can stably lift the left side and the right side of the front bed board 21 and the middle bed board 22 upwards without obstruction.

When a patient wants to turn over to the right side, namely, the patient changes from lying down to lying on the right side, the controller controls the first power device to lift the left sides of the front bed board 21 and the middle bed board 22 to the upper right side, and the patient can complete the turning over to the right along with the front bed board 21 and the middle bed board 22 lifted to the upper right side. Specifically, the controller controls the first hydraulic cylinder 31 to extend, and the left sides of the front bed plate 21 and the middle bed plate 22 hinged to the first hydraulic cylinder 31 are lifted to the upper right under the action of the first hydraulic cylinder 31. In the process, because the two adjacent left and right long laths 20 are hinged, the long laths 20 positioned at the left parts of the front bed plate 21 and the middle bed plate 22 are lifted from left to right in sequence, thereby helping the patient turn over to the right. Therefore, when the lying position of the patient is inclined to the right, the patient can be helped to turn over only by properly increasing the amplitude of lifting the front bed plate 21 and the middle bed plate 22 to the upper right; when the lying position of the patient is deviated to the left, the patient can be prevented from turning over excessively by only properly reducing the amplitude of lifting the front bed board 21 and the middle bed board 22 to the right upper side. After the turning over is finished, the controller controls the first hydraulic cylinder 31 to retract, so as to drive the left sides of the front bed plate 21 and the middle bed plate 22 to return to the horizontal position again.

Similarly, when the patient wants to turn over to the left, i.e. the patient lies down to lie on the left side, the controller controls the second power device to lift the right side of the front bed plate 21 and the middle bed plate 22 to the upper left side, and the patient can turn over to the left along with the front bed plate 21 and the middle bed plate 22 lifted to the upper left side. Specifically, the controller controls the second hydraulic cylinder 32 to extend, and the right sides of the front bed plate 21 and the middle bed plate 22 hinged to the second hydraulic cylinder 32 are lifted to the upper left side by the second hydraulic cylinder 32. In the process, because the two adjacent left and right long laths 20 are hinged, the long laths 20 positioned at the right parts of the front bed plate 21 and the middle bed plate 22 are sequentially lifted from right to left, thereby helping the patient turn over to the left. Similarly, when the lying position of the patient is deviated to the left, the patient can be helped to turn over only by properly increasing the amplitude of lifting the front bed plate 21 and the middle bed plate 22 to the left upper part; when the lying position of the patient leans to the right, the patient can be prevented from turning over excessively by only properly reducing the amplitude of lifting the front bed board 21 and the middle bed board 22 to the left upper side. After the turning over is finished, the controller controls the second hydraulic cylinder 32 to retract, so as to drive the front bed board 21 and the right side of the middle bed board 22 to return to the horizontal position again.

When the nursing bed related to the invention is used for helping the patient turn over, due to the self-gravity of the lifted long lath 20 and the weight of the patient, the parts of the left and right sides of the front bed board 21 and the middle bed board 22 which are respectively lifted to the upper right and the upper left are not too straight, but form certain downward-bending radian, thereby greatly increasing the comfort level of the patient when turning over.

When the patient wants to lie on the right side instead of the flat side, the controller controls the first hydraulic cylinder 31 to extend out, so that the left sides of the front bed board 21 and the middle bed board 22 are lifted to the right upper side to a proper position, and the back of the patient leans against the front bed board 21. Then, the controller controls the second hydraulic cylinder 32 to extend, so as to raise the front bed plate 21 and the middle bed plate 22 upward and leftward, and at the same time, controls the first hydraulic cylinder 31 to retract at the same speed, so as to lower the front bed plate 21 and the middle bed plate 22 downward and leftward. The patient can lie down from the right side to the flat side by lifting the right sides of the front bed board 21 and the middle bed board 22 to the left upper side. After the turning over is finished, the controller controls the second hydraulic cylinder 32 to retract, so as to drive the front bed board 21 and the right side of the middle bed board 22 to return to the horizontal position again. As the left sides of the front bed board 21 and the middle bed board 22 are lifted upwards and rightwards at the beginning of changing the patient from lying on the right side to lying on the flat bed, the back of the patient leans against the front bed board 21, and then the left sides of the front bed board 21 and the middle bed board 22 fall down to the horizontal direction at the same speed as the left sides of the front bed board 21 and the middle bed board 22 are lifted upwards and leftwards, the back of the patient leans against the front bed board 21 all the time in the whole process of changing the patient from lying on the right side to lying on the flat bed, and therefore the patient can stably change from lying on the right side to lying on the flat bed.
