Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nursing bed which is convenient for rapid recovery of lower limb joints after surgery. Background Art

[0002] Nursing beds are used for rehabilitation care of patients. The inclination of the bed board relative to the ground of existing common nursing beds is adjustable, so that it is convenient for patients to lie on the bed board or get up from the bed. The inclination angle of the bed board can be adjusted to any angle, and the inclination angle can even be that the entire bed board is perpendicular to the ground. Nursing beds are not only convenient for nursing staff to care for patients, but some existing nursing beds also have some rehabilitation structures designed to facilitate patients to perform rehabilitation training on the nursing beds. For example, installing a weight-bearing structure on the nursing bed can increase weight-bearing exercise, and installing an electric stimulation device can perform electric stimulation exercise.

[0003] At present, nursing beds are used in the field of rehabilitation. After observation by rehabilitation medical staff, it is found that for some patients with damaged lower limb joints, such as the Achilles tendon and the meniscus of the knee joint, by standing the nursing bed upright from time to time, the body's own weight will have a gravity effect on the heel, and gravity can stimulate the recovery of the lower limb joint cartilage, which is more effective than lying horizontally on the bed board. Therefore, when conducting postoperative rehabilitation training for lower limb joints, medical staff will tie the patient's torso and legs to the bed board with straps, and then stand the bed board upright, so as to stimulate the lower limb joints through the body's own weight.

[0004] However, after the bed board is upright, that is, after the human body is upright, the current nursing bed cannot meet the human body's further movements, such as bending over, because the human body is tied to the bed board. In fact, bending over from time to time can stretch the lower limb joints, which can further stimulate the exercise and rehabilitation of the lower limb joints. Even if the gravity is further concentrated on one foot, it can be more conducive to promoting the rehabilitation training of the lower limb joints. Utility Model Content

[0028] The bed board structure 20 includes a lower limb support board 21, an upper limb support board 22 hinged at one end of the lower limb support board 21, and a swing drive mechanism 23 for driving the upper limb support board 22 to rotate relative to the lower limb support board 21. The lower limb support board 21 is used to support the user's lower limbs, and a plurality of binding belts 24 are installed on both sides of the lower limb support board 21 to allow the user, such as a patient or a convalescent, to lie on the bed board structure 20 and fix their legs on the lower limb support board 21 through the binding belts 24.

[0029] The upper limb support board 22 is used to support the upper limbs of the user. Similarly, a plurality of binding belts 24 (not shown) can be relatively installed on both sides of the upper limb support board 22, so that after the user lies on the bed structure, the binding belts 24 can be used to fix the upper limbs of the human body on the upper limb support board 22. Armrests 221 are further arranged on both sides of the upper limb support board 22 to facilitate the user's support. It can be understood that users with less serious injuries do not need to be bound by the binding belts 24, and can just hold the armrests 221, so the binding belts 24 can be omitted.

[0030] refer to Figure 3 and Figure 4The swing drive mechanism 23 includes a mounting frame 231 and a driving member 232. The mounting frame 231 is fixedly connected to the lower limb support plate 21 and extends into the bottom of the upper limb support plate 22. The driving member 232 is mounted on the mounting frame 231 and is located at the bottom of the upper limb support plate 22.

The driving cylinder 32 is installed on the bottom frame 11 of the bed frame 10, and the piston rod 321 of the driving cylinder 32 is hinged to the lower limb support plate 21. The driving cylinder 32 preferably adopts a hydraulic cylinder, and the piston rod 321 of the hydraulic cylinder is extended and retracted to drive the lower limb support plate 21 to swing relative to the hinged end of the hinge rod 31. When the piston rod 321 is extended to a certain length, the lower limb support plate 21 is perpendicular to the bottom frame 11, that is, perpendicular to the ground. At this time, the human body is equivalent to standing. When the piston rod 321 is fully retracted, the lower limb support plate 21 is parallel to the bottom frame 11, that is, parallel to the ground. At this time, the human body is equivalent to lying flat on the bed board structure 20.

[0032] refer to Figure 5 and Figure 6There are two foot pedal structures 40, which are respectively arranged at the lower end of the lower limb support plate 21 in a liftable manner. By adjusting the lifting and lowering of the foot pedal structure 40, the user's own weight can be concentrated on one foot, and the two feet can bear the weight in turn. The foot pedal structure 40 includes a pedal body 41, a pedal lifting adjustment structure 42, and a pedal inclination adjustment structure 43. The pedal lifting adjustment structure 42 includes a lifting guide plate 421, a lifting slide plate 422 and a lifting drive mechanism 44. The lifting guide plate 421 is fixedly installed at the end of the lower limb support plate 21 and extends a preset length along the length direction of the lower limb support plate 21. The lifting slide plate 422 is connected to the lifting guide plate 421 and can slide relative to the lifting guide plate 421 (such as the cooperation of a slide groove and a slide rail). The lifting drive mechanism 44 can adopt A motor-screw mechanism is used, including a motor 441 and a screw 442. A plate portion is extended on one side of the lifting slide 422 and a threaded hole is opened to cooperate with the screw 442, so that when the motor 441 rotates, the lifting slide 422 is driven to rise and fall relative to the lifting guide plate 421. By connecting the pedal body 41 to the lifting slide 422, the pedal body 41 is driven to rise and fall together when the lifting slide 422 is raised and lowered. It can be understood that the lifting drive mechanism 44 can also adopt a cylinder drive mechanism, and the lifting slide 422 is driven to slide by the cylinder drive mechanism.

The adjusting wheel 434 has an internal thread that cooperates with the thread on the vertical rod section. In this way, by rotating the adjusting wheel 434, the vertical rod section of the T-bar 433 will be caused to rise and fall relative to the connecting rod, thereby driving the hinged end of the pedal body 41 relative to the vertical plate 431 to swing. In this way, the inclination of the pedal body 41 can be adjusted, which can meet the adjustment of the inclination of the sole of the foot against the pedal body 41, that is, the comfort adjustment of the foot.

[0034] refer to Figure 7 Furthermore, in order to facilitate the user to lie in the center of the bed board and to facilitate the binding and bonding of the binding belt 24 (more commonly using magic tape), a partition rod 25 is fixedly set in the middle of the lower limb support board 21 along the length direction. The partition rod 25 relatively separates the lower limb support board 21, and the lower end of the partition rod 25 can be passed through by the binding belt 24 and then reversed and bonded.

[0035] Furthermore, in order to improve the comfort of the user lying on the bed structure 20 , soft cushions are provided on the lower limb support plate 21 and the upper limb support plate 22 .

[0036] When using the above nursing bed for lower limb joint postoperative rehabilitation, the user lies on the bed board structure 20, fixed by the binding belt 24, and can adjust the pedal inclination adjustment structure of the foot pedal structure 40 to meet the user's stepping comfort, and then the bed board structure 20 is driven by the bed board driving device 30 to swing to an upright position, and then the upper limb support plate 22 is driven by the driving member 232 of the swing drive mechanism 23 to swing back and forth relative to the lower limb support plate 21 around the hinge to achieve the user's waist bending, improve the force on the lower limb joints, and further adjust the lifting and lowering of the two foot pedal structures 40 to achieve the weight bearing of the two feet in turn. In this way, it is conducive to the rehabilitation training of lower limb joints after surgery and facilitates the rapid rehabilitation of lower limb joints after surgery.
