Description
Technical Field
The invention relates to the technical field of human body auxiliary instruments, in particular to a multifunctional linkage type nursing wheelchair.
Background
The rehabilitation medical field has a plurality of rehabilitation devices, wherein a wheelchair is paid attention as an auxiliary device for people with mobility impairment. As the number of disabled people increases, particularly lower extremity paralyzed patients, the need for wheelchairs increases. Despite the assistance of wheelchairs, the daily activities of these people still need assistance from caregivers. On the one hand, nursing staff needs to have enough physical strength, the labor cost is continuously increased, on the other hand, the wheelchair can also cause damage to lumbar vertebra after long-term use, meanwhile, the nursing staff needs treatment assistance of rehabilitation nursing staff along with lower limb edema, pressure sore and other adverse complications. At present, a wheelchair structure integrating functions of pose conversion, toilet and mutual transfer between a bed and a chair is not available. When the existing standing wheelchair on the market is changed into a standing state (standing state and prone state are both standing states, and a human body is in a straight line), the human knee joint is positioned at the front end of a standing rotating point of the wheelchair when sitting, so that a person can slide relative to a seat plate when changing from sitting to standing/prone states.
In the prior art, although some wheelchair structures capable of mutually transferring between bed and chairs exist, the wheelchair structures have a plurality of problems such as lack of auxiliary standing and toilet functions, insufficient width of a back plate, incapability of realizing conversion from sitting posture to lying posture, high manufacturing cost and the like. In addition, the back plate and the push plate of the existing pose-changing wheelchair generally use two linear motors to respectively control the rotation angles of the back plate and the push plate, so that the cost of the wheelchair is increased. The Mecanum wheel used in the existing wheelchair is more suitable for small racing trolleys, and the problem of the deviation of the track of the Mecanum wheel cannot be solved because the load demand of the Mecanum wheel on the wheelchair is small and the traditional suspension mechanism is mostly used.
Therefore, those skilled in the art have been working to provide a multifunctional linked care wheelchair that integrates the functions of pose conversion, toilet and mutual transfer between bed and chairs, and overcomes the problem of track offset of the Mecanum wheels, reducing the overall cost of the wheelchair.

After the preparation work is finished, firstly, the telescopic rod of the standing motor 320 starts to stretch, the seat plate 325 starts to rotate anticlockwise by taking the hinging point of the seat plate 325 and the pose frame 319 as the circle center, and after a proper angle is reached, the seat plate 325 stops, the lying motor 323 drives the back plate 332 before standing, the back plate 332 drives the pose connecting rod 321, the pose connecting rod 321 drives the leg plate 317 again, the back plate 332 and the leg plate 317 are positioned at a proper standing angle, meanwhile, the leg plate 317 drives the parallel connecting rod 316, the parallel connecting rod 316 drives the telescopic pipe 315, the telescopic pipe 315 drives the telescopic column 313 to drive the foot rest 312, the foot rest 312 and the leg plate 317 are positioned at a proper standing angle, and the sliding distance caused by the inconsistent rotation point of the knee of a human body and the rotation point of a wheelchair standing can be continuously supplemented in the movement process. When the standing is finished to be reset, the buffer rubber 322 buffers the collision between the rear end of the sitting plate 325 and the rear end of the pose frame 319, and then manually resets the guard rail 329 and the leg guard 317.
Lying posture: the telescopic rod of the lying motor 323 drives the back plate 332, the back plate 332 drives the pose connecting rod 321, and the pose connecting rod 321 drives the leg plate 317, so that the back plate 332 and the leg plate 317 are positioned at an angle parallel to the horizontal plane, and lying is realized. During the movement, the hydraulic damping rod 324 on the other side moves synchronously, so that the whole movement process is more stable.
Docking posture of bed and chair: when the wheelchair is in butt joint with a bed, manual assistance is needed, the rollers 329 are utilized to adjust the armrest 330 to form a horizontal angle with the backboard 332, then, lying transformation in a lying posture is carried out, and the lifting mechanism 2 is utilized to enable the upper surface of the wheelchair in the lying posture to be positioned on the same horizontal plane with the upper surface of the bed to be transferred, and then, a nursing staff can directly utilize transfer cloth or directly manually transfer a user.
As shown in fig. 6, the toilet mechanism 4 includes a toilet cover 433 hinged inside the seat 325, and a toilet linear motor 436 fixed inside the seat 325 by means of a toilet motor fixing seat 437, a guide cap 435 fixed to the front end of a telescopic rod of the toilet linear motor 436, one end protruding cylinder of the guide cap 435 engaged with a notch on the toilet cover 433 and connected to the guide rod 434, the other end protruding cylinder of the guide cap 435 engaged with a notch fixed to the seat 325, and the other end protruding cylinder of the guide rod 434 engaged with a notch fixed to the seat 325 through a notch on the toilet cover 433, thereby relieving torque due to gravity of a person sitting on the toilet cover 433.
In the toilet mechanism 4 of the embodiment, before the wheelchair is docked with the domestic toilet by means of the moving mechanism 1, the toilet linear motor 436 contracts the telescopic rod thereof, and the telescopic rod drives the toilet cover 433 to turn downwards by means of the guide cap 435 matched with the notch on the toilet cover 433, so that a toilet docking ring for toilet is arranged on the inner side of the seat 325, and excrement of a patient can be directly discharged into the toilet after the wheelchair is docked with the domestic toilet. After the toilet is finished, the toilet linear motor 436 stretches the telescopic rod to reset the toilet cover 433 according to the linkage mode when the toilet is contracted.
As shown in fig. 7, the navigation mechanism 5 includes a storage box 538 fixed in the middle of the uppermost end of the back plate 332, for storing the three-dimensional radar 539 fixed inside the navigation telescopic rod 540, and telescopic buttons 541 with three springs fixedly arranged inside the left and right circular passages of the navigation telescopic rod 540, wherein the navigation telescopic rod 540 is arranged inside the two square passages at the rear side of the back plate 332, and the storage and the extension of the three-dimensional radar 539 are realized by means of the telescopic buttons 541.
In the navigation mechanism 5 of the present embodiment, during navigation, the telescopic rod 540 extends out from the two square tubes at the rear side of the back plate 332, and the small cylinder on the telescopic button 541 is clamped in the small round hole in the two square tubes, so that the three-dimensional radar 539 is located at the topmost end of the wheelchair, and performs the scanning work of daily navigation. During bathing, since the whole wheelchair enters the bathroom, the three-dimensional radar 539 needs to be waterproof, manual assistance is needed, and the telescopic button 541 inside the telescopic rod 540 is pressed to enable the telescopic rod 540 to retract into the two square tubes on the rear side of the back plate 332, so that the three-dimensional radar 539 is recovered into the storage box 538, and liquid is prevented from entering.
The multifunctional linkage type nursing wheelchair provided by the embodiment is shown in fig. 9 and 11 in a use state in a sitting posture, and is shown in fig. 10 in a prone position.
The foregoing describes in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the invention without requiring creative effort by one of ordinary skill in the art. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
