Description

Technical Field

[0001] The present invention relates to the technical field of nursing equipment, and in particular to a medical surgical nursing device based on medical ergonomics. Background Art

[0002] The famous saying "three parts treatment, seven parts care" is a scientific summary of medical practice. After some surgical operations, patients will lose the ability to take care of themselves. At this time, care for patients also includes helping them to move. Some patients who have just undergone surgery cannot move by themselves after returning to the hospital bed, and they do not even have the ability to sit up from the bed. Hospital beds are usually equipped with rockers that can raise the head of the bed to help patients sit up.

[0003] Chinese invention CN201911256134.9 discloses a medical surgical nursing device based on medical ergonomics, comprising a bed and a sitting board mounted on the bed, the sitting board comprising a fixed board and a swingable movable board. In this medical surgical nursing device based on medical ergonomics, the spinal rod is adjusted in curvature by the action of an airbag, so that the curvature ultimately conforms to the curvature of the human lumbar spine. This effectively supports the lumbar spine when the patient is sitting up. When caring for patients who are unable to take care of themselves and have been bedridden for an extended period, the spinal rod and shoulder straps are used to place the patient in a sitting position, exposing a larger area of the back, making it easier for nursing staff to massage and clean the back. At the same time, the air pressure in the airbag is increased, slightly lifting the patient's spine, reducing pressure between the patient's back and buttocks and the bed, promoting blood flow to the back and buttocks, and increasing the time interval between massages.

[0004] However, this device has limitations. First, as the human body ages, the spacing between the lumbar joints and the curvature become different. Second, for some patients who need lumbar correction, their lumbar spine is pathological and has scoliosis, so this nursing device is not suitable for care. Summary of the Invention

The sitting board 2 can be lifted by a lifting mechanism to assist the patient to sit, and the interior of both ends of the sitting board 2 are connected to parallel large-stroke spacing adjustment rods 5 through bearings, and the outer sides of both ends of the large-stroke spacing adjustment rods 5 are sleeved with connecting blocks 7, and two back plates 8 perpendicular to the large-stroke spacing adjustment rods 5 are fixed by bolts of the connecting blocks 7, and the outer sides of the ends of the two large-stroke spacing adjustment rods 5 are sleeved with synchronous pulleys, and the outer sides of the synchronous pulleys are wrapped with synchronous belts 6, and the surfaces of the two ends of the large-stroke spacing adjustment rods 5 are respectively provided with forward threads and reverse threads, and the inner walls of the connecting blocks 7 at both ends are respectively provided with thread grooves that mesh with the forward threads and reverse threads, which makes it possible to rotate one of them The large stroke spacing adjustment rod 5 can use the synchronous belt 6 to drive the two synchronous rotations, thereby driving the two sets of connecting blocks 7 connected by the forward and reverse threads at both ends to realize reverse synchronous transmission, thereby achieving the function of adjusting the spacing between the two back plates 8, so as to adjust the large stroke of the back plate 8 according to the lumbar vertebrae spacing or lumbar vertebrae deviation degree of different patients. A sliding seat 9 is movably installed on the inner side of the bottom of the back plate 8, and a vertical plate 10 is welded above the left end of the sliding seat 9. A slider is provided on the inner side of the bottom of the back plate 8, and a sliding groove corresponding to the slider is opened at the bottom of the sliding seat 9. The end of the sliding seat 9 is fixed to the one side surface of the back plate 8 by a locking bolt 14, which makes it possible to adjust the lateral position of the sliding seat 9 inside the back plate 8 through the locking bolt 14 and lock and fix it, so as to adjust the lumbar vertebrae joint spacing of patients of different age groups, and has stronger adaptability;

[0031] The interior of the vertical plate 10 is connected to a small-stroke spacing adjustment rod 11 that passes through and extends to the outside of one side of the back plate 8 through a bearing. The outside of the small-stroke spacing adjustment rod 11 is sleeved with a transverse telescopic rod 12. An adjustment ring 15 is welded to the end of the small-stroke spacing adjustment rod 11. The surface of the adjustment ring 15 is provided with a thread. The inner wall of the transverse telescopic rod 12 is provided with a thread groove corresponding to the thread on its surface. This allows the small-stroke spacing adjustment rod 11 to be rotated to drive the transverse telescopic rod 12 connected to its outside to be extended and retracted by utilizing the thread of the adjustment ring 15, thereby pushing the top ball 20 installed on the top of the transverse adjustment rod 12 to adjust the small-stroke spacing above the back plate 8, so that the top ball 20 can be adjusted to act on the patient's lumbar vertebra for auxiliary support.

[0032] A vertical frame 16 is provided above one end of the transverse telescopic rod 12, and a lower end of the vertical frame 16 is connected to a rotating rod 18 that passes through and extends to the inside of the transverse telescopic rod 12 through a bearing. The inner side of the other end of the transverse telescopic rod 12 is also connected to a height adjustment rod 17 that passes through and extends to the outside of the end of the small stroke spacing adjustment rod 11 through a bearing. The top outer side of the rotating rod 18 is threadedly connected to a longitudinal telescopic rod 19 that passes through and extends to the outside of the top of the back plate 8, and a top ball 20 is fixed through the longitudinal telescopic rod 19. The outer side of the end of the height adjustment rod 17 is sleeved with a driving gear 21, and the outer side of the rotating rod 18 is located inside the transverse telescopic rod 12 and is sleeved with a transmission gear 22 that meshes with the driving gear 21. In the process of rotating the height adjustment rod 17, the driving gear 21 and the transmission gear 22 can be used to drive the rotating rod 18 to rotate, thereby driving the longitudinal telescopic rod 19 threaded at its top to push the top ball 20 to extend and retract, so as to adjust the support point of the top ball 20 according to the patient's physiological curve. The structure is simple and practical.

[0033] The top of the sliding seat 9 and the inner wall of the stand 16 are respectively welded with a first limit plate 13 and a second limit plate 23. The outer sides of the ends of the transverse telescopic rod 12 and the longitudinal telescopic rod 19 are respectively provided with corresponding guide grooves, which can effectively prevent the transverse telescopic rod 12 and the longitudinal telescopic rod 19 from rotating.

[0034] Furthermore, both end surfaces of the sitting board 2 are provided with cushions 3 covering the top of the backboard 8, and the interior of the cushions 3 is provided with a cushioning airbag 4, which greatly improves the comfort of the top ball 20 support during patient care.
