[0002] The symptoms of Alzheimer's patients mainly include short-term or medium-term memory loss, language barriers, impaired judgment and comprehension, lack of patience and behavioral changes, which lead to the unsafe risk of Alzheimer's patients getting lost when traveling alone. Alzheimer's patients are generally elderly people, and elderly Alzheimer's patients cannot walk long distances due to physical limitations. Therefore, many elderly Alzheimer's patients are accustomed to traveling in electric wheelchairs. When Alzheimer's patients are in a state of short-term memory loss and getting lost after traveling in a wheelchair, the patients are prone to confusion and at a loss due to impatience, and are unable to contact their families or seek help from passers-by. When patients stay on the road for a long time, their decreased judgment and comprehension will also put them in danger. Therefore, before traveling alone, Alzheimer's patients will carry mobile phones or special positioning devices with GPS functions so that their families can quickly find them.

DETAILED DESCRIPTION

[0025] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0026] Example 1

[0027] A special wheelchair for Alzheimer's disease patients based on a medical big data system, hereinafter referred to as the wheelchair, Figure 1-Figure 6As shown, it includes a carrier frame 11, a power motor module 12, an electric drive wheel 13, an electric steering wheel 14, an electric hydraulic rod 15, an armchair 2, an unlocking button 23, a flap 31, a fixing plate 32, a foot pedal 33, a connecting arm 35, a sliding block 36, a pad 37, a support rod 41, an armrest 42, a protection rod 43, a support mechanism, a control rocker 6 and a navigator 7; the power motor module 12 is installed on the carrier frame 11, and the power motor module 12 is composed of a charging power battery module, a driving motor module and a master control module for controlling the charging power battery module and the driving motor module; the power motor module 12 is installed on the carrier frame 11, and the power motor module 12 is composed of a charging power battery module, a driving motor module and a master control module for controlling the charging power battery module and the driving motor module; The general control module of the motor module 12 is provided with a GPS positioning system and a medical big data user feedback system; two electrically controlled driving wheels 13 and two electrically controlled steering wheels 14 are sequentially mounted on the carrier frame 11; a reclining chair 2 is rotatably connected to the carrier frame 11; two electrically controlled hydraulic rods 15 are rotatably connected to the carrier frame 11 via a rotating shaft; the telescopic ends of the two electrically controlled hydraulic rods 15 are respectively rotatably connected to the reclining chair 2 via a rotating shaft; the end of the carrier frame 11 close to the electrically controlled steering wheel 14 is rotatably connected to a flap 31 via a rotating shaft; two fixed plates 32 are connected to the flap 31; and one is connected to each of the two fixed plates 32. The footrest 33; two connecting arms 35 are fixedly connected to one side of the flap 31 away from the fixed plate 32; each of the two connecting arms 35 is rotatably connected to a sliding block 36; both sliding blocks 36 are slidably connected to the armrest 2; a pad 37 is fixedly connected between the two connecting arms 35; two supporting rods 41 are fixedly connected to the armrest 2, and the supporting rods 41 are symmetrically distributed on both sides of the support frame 11; each of the two supporting rods 41 is rotatably connected to an armrest 42; each of the two armrests 42 is fixedly connected to a protective rod 43, and the two protective rods 43 are located above the area where the support frame 11 supports the legs of the occupant; There are two card plates 44 that are symmetrical to each other on the left and right; the rear ends of the two armrests 42 are respectively provided with a card slot 420 structure corresponding to the card plate 44; an unlocking button 23 is installed on each of the two armrests 42, and pressing the unlocking button 23 will feedback to the power motor module 12 to control the electric hydraulic rod 15 to complete the unlocking action; the two electric drive wheels 13, the two electric steering wheels 14, the two electric hydraulic rods 15 and the two unlocking buttons 23 are all electrically connected to the power motor module 12 through the circuit system; the carrier frame 11 is installed with a control rocker 6 through a supporting mechanism; and a navigator 7 is installed on the supporting mechanism.

[0028] like Figure 2 As shown, two handles 21 are fixedly connected to the armchair 2 and are symmetrical to each other. A speaker 22 is installed on the armchair 2. The speaker 22 is electrically connected to the power supply motor module 12 through a circuit system.

[0029] Before an Alzheimer's patient travels in the wheelchair, he first rotates the two armrests 42 to drive the two protection rods 43 to flip up. After the patient sits on the backrest 2 of the wheelchair, he steps on the two footrests 33 with his feet, and then rotates the two armrests 42 in the opposite direction to drive the two protection rods 43 to reset downward, so that the two protection rods 43 flip down and cross over the patient's thighs, providing safety protection for the patient sitting on the backrest 2 to prevent the body from leaning forward. The patient can then operate the control joystick 6 to control the power motor module 12 to drive the electronically controlled driving wheel 13 and the electronically controlled steering wheel 14 to drive the wheelchair to move, and go out with the help of the navigation function of the navigator 7.

[0030] The power motor module 12 has a built-in GPS positioning system and a medical big data user feedback system. Whenever a patient travels in the wheelchair, the medical big data user feedback system built into the power motor module 12 will actively update the travel status of the wheelchair in real time and feedback it to the patient's family through the information sending and receiving software matched by the system. At the same time, the GPS positioning system built into the power motor module 12 will also update the travel location of the wheelchair in real time and feedback it to the patient's family through the medical big data user feedback system. In addition, the family members can also use the matching information sending and receiving software to define a permitted movement area for the wheelchair, and the GPS positioning system built into the power motor module 12 will automatically monitor and determine whether the wheelchair is in the permitted movement area.

[0031] When the GPS positioning system built into the power motor module 12 detects that the patient has moved the wheelchair to the edge of the permitted movement area, or when the GPS positioning system built into the power motor module 12 detects that the patient has moved the wheelchair to a dangerous area such as a river bank or a construction site, the power motor module 12 will promptly control the electronically controlled drive wheel 13 to slow down the driving speed. At the same time, the power motor module 12 controls the audio 22 to issue a warning to the patient on the wheelchair to turn around and leave the current area, so that the patient can actively control the control joystick 6 to control the wheelchair to make a corresponding turn and leave action.

[0032] During the process of the power motor module 12 issuing a warning to the patient in the wheelchair to turn around and leave the current area, if the built-in GPS positioning system of the power motor module 12 detects that the wheelchair is still moving towards the dangerous area five seconds after the warning is issued, the power motor module 12 will control the wheelchair to switch to the anti-lost mode. Under the control of the power motor module 12, the electric-controlled hydraulic rod 15 pushes the backrest 2 to flip backward twelve degrees, so that the patient sitting on the backrest 2 is in a semi-lying state backward. At the same time, the front side of the backrest 2 pulls the sliding block 36 and the connecting arm 35 connected to it to deflect forward and upward during the upward tilting process. At the same time, the connecting arm 35 drives the flap 31 to flip forward and downward around the axis of the rotating shaft connected to the support frame 11. At the same time, the flap 31 drives the fixed plate 32 and the foot pedal 33 to flip forward and downward away from the patient's feet. Figure 8As shown, the patient in a semi-reclining state has his feet suspended in the air and cannot easily obtain effective stepping support to stand up, and at this time, the connecting arm 35 drives the pad 37 to flip forward to fit closely to the patient's calf, so that the patient's calf can obtain sufficient support and is not easily sore, thereby making the patient suspended on the backrest 2 of the wheelchair and unable to stand up, thereby preventing the patient from easily leaving the wheelchair and increasing the difficulty for the patient's family to find him. At the same time, the backrest 2 will also drive the armrest 42 to flip backward and approach the card plate 44, so that the armrest 42 is locked on the card plate 44 through the card slot 420. At this time, the patient suspended on the backrest 2 of the wheelchair cannot actively push away the protection rod 43 on the armrest 42, and the protection rod 43 restricts the patient's thigh on the backrest 2 to prevent the patient on the backrest 2 from making a large-scale struggle to break free and causing the wheelchair to tip over.

[0033] After the wheelchair is switched to the anti-lost mode, the medical big data user feedback system built into the power motor module 12 will actively send a distress signal and current location information to the patient's family through the information receiving and sending software matched by the system, so that the patient's family can come in time to lead the patient on the recliner 2 home. The patient's family or other personnel who actively provide assistance to the patient need to press the unlock button 23 to allow the power motor module 12 to control the electronically controlled hydraulic rod 15 to retract and drive the wheelchair to switch to its original normal state, so that the patient can resume a normal sitting position under the supervision of the person providing assistance, and the person providing assistance can push the handle 21 and operate the control joystick 6 to go home with the help of the navigation function of the navigator 7.

[0034] Example 2

[0035] like Figure 1-Figure 6 As shown, on the basis of Example 1, the two fixed plates 32 of this embodiment are slidably connected to the flap 31, and the height of the foot pedal 33 can be adjusted by moving the fixed plate 32 along the flap 31 in the up and down directions, so that patients of different heights can step on the foot pedal 33 more easily; the two fixed plates 32 are respectively fixed to the flap 31 by bolts; the two foot pedals 33 are respectively rotatably connected to the corresponding fixed plates 32, and the foot pedals 33 can only rotate upward; two torsion springs 34 are fixedly connected between the two foot pedals 33 and the corresponding fixed plates 32.

[0036] When the foot pedal 33 moves down to the limit distance with the fixed plate 32, and the special wheelchair for Alzheimer's patients based on the medical big data system of the present invention is switched to the anti-lost mode, the flap 31 drives the foot pedal 33 on the fixed plate 32 to flip downward. In the process, the foot pedal 33 closer to the ground will be blocked by the ground due to the limitation of the flatness of the ground itself. If the foot pedal 33 is not rotatably connected to the fixed plate 32, the foot pedal 33 will be directly broken. Therefore, a torsion spring 34 is designed, and the foot pedal 33 drives the torsion spring 34 to twist, so that the downward flipped flap 31 and the fixed plate 32 will not break the foot pedal 33 due to obstruction from the ground.

[0037] Example 3

[0038] like Figure 1-Figure 7 As shown, on the basis of Example 1, the support mechanism of this embodiment includes a support frame 51, a swing arm 52, a spur gear 53, an electric slider 54, a spur rack 55 and a mounting plate 56; the support frame 51 is fixedly connected to the carrier frame 11; two swing arms 52 in parallel to each other are rotatably connected to the support frame 51; a mounting plate 56 is rotatably connected between the upper ends of the two swing arms 52; the control joystick 6 and the navigator 7 are both installed on the mounting plate 56; the front swing arm 52 is fixedly connected to the spur gear 53; the electric slider 54 is slidably connected to the support frame 51; the electric slider 54 is fixedly connected to the spur rack 55; the spur rack 55 is meshed with the spur gear 53.

[0039] When the wheelchair for Alzheimer's patients based on the medical big data system of the present invention is switched to the anti-lost mode, the electric slider 54 drives the spur rack 55 to move, and after engaging the spur gear 53, further drives the swing arm 52 to rotate, so that the swing arm 52 drives the mounting plate 56 and the control rocker 6 and the navigator 7 connected thereto to suspend upward and backward, forming a Figure 8 The state shown in the figure is shown, and the control authority of the control joystick 6 to the electric control driving wheel 13 and the electric control steering wheel 14 is turned off, making it difficult for the patient on the armchair 2 to touch and control the control joystick 6 to control the movement of the wheelchair. Only after the person providing assistance presses the unlock button 23, the control authority of the control joystick 6 to the electric control driving wheel 13 and the electric control steering wheel 14 can be restored. When the person providing assistance stands behind the wheelchair and pushes the wheelchair forward, the control joystick 6 and the navigator 7 are suspended to the side of the person providing assistance, as shown in the figure. Figure 8 As shown, the person providing assistance can more easily manipulate the control joystick 6 to control the movement of the wheelchair, and at the same time more easily view the home navigation route provided by the navigator 7.
