Description

Technical Field

[0001] The utility model relates to the technical field of nursing beds, in particular to a nursing bed. Background Art

[0002] During the care of critically ill patients or patients with poor muscle strength, since the patients themselves cannot achieve a sitting or semi-lying posture independently, the bed board where the patient's upper body is located needs to be tilted 30° to 45° to support the patient to maintain a sitting or semi-lying posture. When maintaining a sitting or semi-lying posture, the patient slides down due to his own gravity, and there is a situation where the patient's feet are against the footboard after sliding down. After the tilted bed board changes from an inclined state to a horizontal state, the patient changes from a sitting or semi-lying posture to a lying posture. At this time, the patient's feet are still against the footboard of the bed. If the nursing staff does not move the patient, the patient's feet will be against the footboard of the bed for a long time, which is very likely to cause problems such as redness of the soles of the feet and pressure sores.

[0003] When the patient changes from a sitting position to a lying position, in order to prevent the patient's feet from hitting the footboard of the bed, the existing practice is that the nurse moves the patient up to keep the patient's feet away from the footboard. The existing practice is time-consuming and labor-intensive. At the same time, when there is only one nurse, it is impossible to move a heavy patient. Utility Model Content

Figure 8 The inner frame 620 is provided with a slider 624 which is slidably connected to the slide groove 614. Fig.11As shown. The support member 630 is rotatably connected to the inner frame 620. Specifically: the outer frame 610 is disposed in the inner cavity of the first bed board 200 and is fixedly connected to the bottom surface of the first bed board 200. When the side support assembly 600 is in the storage state, the outer frame 610, the inner frame 620 and the support member 630 are arranged in sequence from the outside to the inside.

[0076] In this embodiment, the side support assembly 600 is used as follows: Figure 5 , Figure 6 and Figure 7 As shown: first, pull the inner frame 620 out of the installation cavity of the outer frame 610 through a pulling operation; secondly, adaptively adjust the angle between the inner frame 620 and the outer frame 610, and limit the connection between the inner frame 620 and the outer frame 610; then, release the limit connection between the support member 630 and the inner frame 620; finally, adaptively adjust the angle between the support member 630 and the inner frame 620, and limit the connection between the support member 630 and the inner frame 620, and now the installation of the side support assembly 600 in use state is completed.

[0077] Furthermore, the outer frame 610 further includes a mounting cavity, a first side wall 611, a second side wall 612 and a third side wall 613. Figure 8 The first side wall 611, the second side wall 612, and the third side wall 613 are sequentially connected to enclose the installation cavity, the first side wall 611 and the third side wall 613 are arranged in parallel, and the first side wall 611 and the third side wall 613 are both provided with a slide groove 614, and the second side wall 612, the first side wall 611 and the opening on the first bed board are sequentially arranged from the inside to the outside.
