[0001] The invention relates to the technical field of medical auxiliary devices, in particular to a device for assisting paralyzed patients in sitting balance. Background Art
[0002] Paralysis refers to a disease in which the body completely or partially loses motor function and voluntary movements due to damage to the nervous system and sensory disorders. Paralysis is caused by lesions of the upper and lower motor neurons, pyramidal tracts and peripheral nerves. For paralyzed patients, they need to stay in bed for a long time because of their mobility problems. However, long-term bed rest will not only cause physical injuries such as bedsores, but also be detrimental to mental health. Therefore, it is necessary to adjust the sitting position of paralyzed patients from time to time to ensure their physical and mental health. However, due to the loss of motor function of paralyzed patients, they are unable to adjust their balance when sitting, which makes their posture very easy to tilt and cause them to fall. In this regard, the present application specifically proposes a device to assist paralyzed patients in sitting balance, which is used to ensure the safety of patients in sitting.

[0016] The following is combined with Figure 1-7 The specific implementation modes of the present invention are further described in detail.
[0017] Embodiment 1, the technical solution is that when the present invention is used, the medical staff places the paralyzed patient on the cushion 32 in the center, and then the patient sits on the cushion 32 above the seat plate 1, and the back rests on the backrest 33 fixedly connected to the frame 2, and a waist support 34 is arranged on the lower side of the backrest 33, so as to ensure the comfort of the patient when adjusting the sitting position. In order to ensure the patient's sitting balance, a belt 7 is also arranged. After the patient sits down, the waist and abdomen can be moderately restrained by the belt 7, so as to prevent the patient from slipping down when sitting. Further, the present application is also arranged with a side tilt detection device 9, when the patient's body tilts to the side, the side tilt detection device 9 can be triggered, and when the side tilt detection device 9 is triggered, the driving device 11 will be started through the controller 5, and then the driving device 11 can drive the deviation correction and balance device 12, under the action of the deviation correction and balance device 12, the patient's posture is adjusted and reset, so as to ensure the patient's sitting balance. The present invention has a simple structure, is easy to use, and has strong practicality.
[0018] Embodiment 2, based on embodiment 1, specifically, after the nursing staff places the paralyzed patient in the center on the cushion on the seat board 1 and adjusts the body position, in order to prevent the patient from sliding down and losing balance, it is necessary to first restrain the patient's waist and abdomen through two straps 7 fixedly connected to the clamping block, thereby preventing the patient from losing balance due to sliding down.
[0019] Furthermore, in order to prevent the patient from tilting to one side and losing balance, the seat plate 1 of the present application is also provided with armrests 3 on both sides, which can be used in conjunction with the baffle 4 to limit the patient's waist and abdomen to ensure the patient's sitting balance. Furthermore, in order to prevent the patient from tilting to one side seriously, which may cause the armrests 3 and baffle 4 to fail in their limiting effects, the present application is also provided with a side tilt detection device 9, which can provide timely support to the patient in conjunction with the drive device 11 and the deviation correction and balance device 12, and assist the patient's body in resetting to ensure the patient's sitting balance. In order to ensure the effectiveness of the side tilt detection device 9, multiple groups of side tilt detection devices 9 are arranged along the length direction of the mounting plate 8, and the patient and any group of side tilt detection devices 9 can trigger their effectiveness.
[0020] Specifically, when the patient tilts to one of the left or right sides, the patient's body first contacts the rubber ball 21 of the lateral tilt detection device 9 on the corresponding side, and then the rubber ball 21 is subjected to the pressure of the patient and forces the detection rod 18 to move into the mounting tube 17, and then the spring 19 in the mounting tube 17 is compressed. When the spring 19 is compressed, the pressure sensor 20 is subjected to the pressure from the spring 19. When the pressure reaches the set value of the pressure sensor 20, the pressure sensor 20 transmits this information to the controller 5. After receiving this information, the controller 5 will first start the driving motor 31 of the driving device 11 to rotate forward to the set stroke. The forward rotation of the driving motor 31 will drive the vertical shaft 29 connected to the frame 24 to rotate accordingly, and then the active bevel gear 30 on the vertical shaft 29 will rotate accordingly and drive the horizontal shaft 25 to rotate through the driven bevel gear 28. When the horizontal shaft 25 rotates, the two threaded portions 26 thereon will rotate synchronously. The two threaded portions 26 rotate in opposite directions, and the two moving rods 13 will move relatively close to each other along the horizontal axis 25 under the drive of the two threaded portions 26. The relative close movement of the two moving rods 13 means that the two sets of deviation correcting and balancing devices 12 move relatively close to each other. As the two sets of deviation correcting and balancing devices 12 move relatively close to each other, the thick pad 16 on the side where the patient is tilted will first contact the patient, and thus can provide support for the patient to prevent the patient from continuing to tilt to the side. As the moving rod 13 continues to move, the connecting rod 14 and the thick pad 16 on the deviation correcting plate 15 will move synchronously therewith, and then the thick pad 16 will support the patient's body to be restored to its side. As the patient's body is restored, the patient will recover to a sitting balanced state. The two sets of deviation correcting and balancing devices 12 are respectively located on both sides of the patient, and thus can provide support for both sides of the patient in the process of assisting the patient in resetting, and thus can prevent the patient from tilting to the other side during the resetting process.
[0021] As described above, when the driving motor 31 of the driving device 11 rotates forward for the set stroke of the controller 5, the patient can complete the body reset. Thereafter, the driving motor 31 will stop for the set time under the action of the controller 5, so as to facilitate the patient to stabilize the body position. Then, the motor will reverse and reset under the action of the controller 5, thereby driving the corresponding components such as the correction and balancing device 12 to reset, so as to ensure the patient's comfort and prepare for the patient to tilt to the side again.
[0022] Embodiment 3, on the basis of embodiment 2, a guide groove 22 cooperating with the guide block 23 is arranged on the mounting tube 17, thereby ensuring that the detection rod 18 moves axially along the mounting tube 17, and an outwardly bent protective plate 10 is arranged above the mounting plate 8 to prevent the upper end of the mounting plate 8 from causing harm to the patient when the patient tilts to the side.
