Example 1

This embodiment provides a care bed suitable for patients with pressure sores at high risk of debilitating movement dysfunction, which in a preferred embodiment comprises a bed frame 10, and a head 20, a tail 30 and a surface 40 mounted on the frame 10, as shown in figures 1 and 2. The bed surface 40 comprises two half bed surfaces, a left bed surface and a right bed surface, which are separated by a first dividing line 41 as shown in fig. 2, the left bed surface and the right bed surface being each divided into a plurality of sub-areas 42. Each sub-zone 42 has a lift drive mechanism 60 connected thereto, the lift drive mechanism 60 of each sub-zone 42 being independently operable such that each sub-zone 42 is independently operable.

In one embodiment, as shown in fig. 2, the sub-area 42 is a regular hexagon or a half of a regular hexagon, at least one side of the left and right bed surfaces, which is close to each other, is formed by splicing the regular hexagon and the half of the regular hexagon, and the half of the regular hexagon should be set according to the actual situation, so as to ensure the integrity of the bed surface 40. In another embodiment, as shown in fig. 7, the sub-regions 42 are all rectangular, and a plurality of rectangles are stitched into the deck 40. Of course, the sub-area 42 may be a diamond or half of a diamond, and at least one side of the left and right bed surfaces, which are adjacent to each other, is formed by stitching one half of the diamond or the diamond.

As shown in fig. 3 and 4, in one embodiment, the lift drive mechanism 60 of each sub-zone 42 includes a left drive member 61 on the left side and a right drive member 62 on the right side, and the left and right drive members 61, 62 may be, but are not limited to, linear motors, telescoping cylinders, or air cylinders. The top parts of the left and right driving members 61 and 62 are hinged, preferably ball-hinged, to the left and right sides of the bottom of the sub-area 42, respectively, and the sub-area 42 can be lifted or tilted in the left-right direction by operating the lifting driving mechanism 60.

Specifically, by synchronously extending/shortening the left and right driving pieces 61 and 62, the corresponding sub-region 42 can be raised/lowered; by making the extension length of the right driving piece 62 longer than that of the left driving piece 61, the corresponding subarea 42 can be inclined from bottom to top and from left to right, so that the right bed surface is inclined from bottom to top and from left to right, and the left turn-over of the patient is realized; by extending the left drive member 61 a greater length than the right drive member 62, the corresponding subregion 42 can be tilted from bottom to top, from right to left, and thus the left couch top from bottom to top, from right to left, to achieve a right turn-over of the patient.

In use of the care bed, adjacent sub-areas 42 are alternately raised and lowered. Specifically, the adjacent sub-regions 42 are raised slightly or lowered slightly in part over a period of time to reduce the area of patient contact with the couch top 40, with the lower sub-regions 42 not in contact with the patient or being less pressurized; for another period of time, the lower sub-region 42 is raised or the higher sub-region 42 is lowered to replace the location where the patient is in contact with the couch top 40 to reduce the probability of pressure sores. The number of sub-regions 42 in the figure is merely an example, and in practice, the number of sub-regions 42 is larger to ensure that a patient can be supported well without uneven feeling even when a part of the sub-regions 42 is lowered.

When a patient needs to turn left, the lifting driving mechanism 60 corresponding to the right bed surface works to enable the right bed surface to incline from bottom to top and from left to right so as to help the patient turn left; when the patient needs to turn right, the lifting driving mechanism 60 corresponding to the left bed surface works to enable the left bed surface to incline from bottom to top and from right to left so as to help the patient to turn right.

Specifically, by having the front drive member 63 extend longer than the rear drive member 64 (where the left and right drive members 61, 62 extend equally and are half the sum of the front and rear drive members 63, 64), the corresponding sub-region 42 can be tilted from bottom to top, front to back, and then the left and right front bed surfaces can be tilted from bottom to back, front to raise the patient's torso and head; by extending the rear drive member 64 more than the front drive member 63 (where the extension lengths of the left and right drive members 61, 62 are equal and half the sum of the extension lengths of the front and rear drive members 63, 64), the corresponding sub-regions 42 can be tilted from bottom to top from front to back, and thus the left and right rear bed surfaces can be tilted from bottom to top from front to back to raise the patient's legs and feet.

When the front driver 63 and the rear driver 64 are added, the left bed surface is inclined from bottom to top to right and left or the right bed surface is inclined from bottom to top to left and right, and the protruding lengths of the front driver 63 and the rear front driver 63 are equal to each other and half of the sum of the protruding lengths of the left driver 61 and the right driver 62.
