Description

Technical Field

[0001] The invention belongs to the technical field of orthopedic protective devices, and specifically refers to an anti-fall protective device for nursing osteoporosis patients. Background Art

[0002] Osteoporosis is a systemic bone disease caused by a variety of reasons. Its main characteristics are decreased bone density and bone quality, damage to bone microstructure, increased bone brittleness, and a state prone to fractures. Mild cases may have no obvious symptoms, but as the disease progresses, patients feel fatigue, back pain, and even body pain. They are more likely to suffer fractures when they fall or fall. Severe osteoporosis can also cause body deformations such as hunchbacks, requiring timely corrective intervention when the patient is standing or walking. Therefore, osteoporosis patients need to perform appropriate walking exercises in daily care, but they need to use protective devices to support and protect the patients when walking to avoid falls.

[0003] However, in the prior art, there are still some shortcomings in the anti-fall protection device for osteoporosis patients: 1. Some protective devices have a relatively simple structure, which makes it difficult to adjust according to the patient's height or to adjust the auxiliary wheels according to the slope of the road during walking. During use, the patient is easily separated from the protective device, which cannot support the patient in time, increasing the risk of the patient falling; 2. Some protective devices use roller structures to facilitate patient movement, but when the patient stops moving, the rollers will slide due to inertia, resulting in poor stability; 3. Some protective devices cannot protect the patient's key parts without affecting the patient's line of sight, and it is difficult to quickly stabilize the center of gravity of the protective device when the patient is about to fall. Summary of the invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides an anti-fall protection device for nursing osteoporosis patients. The device utilizes the electromagnetic principle in combination with a snap-fit ​​connection structure to provide a retractable and adjustable auxiliary support component. While providing stable auxiliary support, it can be adaptively adjusted according to the slope of the road section, and realizes the rapid conversion of the auxiliary wheels between the rotating state and the emergency stop state, which indirectly increases the ground contact area of ​​the auxiliary wheels, increases the stability of the device, and reduces the risk of patients falling. A first anti-dumping bracket mechanism and a second anti-dumping bracket mechanism are provided. When the patient is about to fall, the device is supported from different directions, the center of gravity of the device is quickly stabilized, the patient is helped to regain the center of gravity, and the device is prevented from completely tipping over and causing the patient to fall to the ground.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the present invention is as follows: the present invention provides an anti-fall protection device for nursing osteoporosis patients, comprising a support frame mechanism, a retractable and adjustable auxiliary support assembly, a first anti-dumping support mechanism, a second anti-dumping support mechanism, a swivel head protection mechanism and a waist protection mechanism, the support frame mechanism is symmetrically arranged, the retractable and adjustable auxiliary support assembly is symmetrically arranged on the front and rear walls of the support frame mechanism, the first anti-dumping support mechanism is arranged in the side wall of the support frame mechanism facing outward, the second anti-dumping support mechanism is symmetrically arranged in the front and rear walls of the support frame mechanism, the swivel head protection mechanism is slidably arranged on the upper part of the support frame mechanism, and the waist protection mechanism is symmetrically arranged on the upper part of the support frame mechanism. The mechanism is arranged on the rotating head protection mechanism, wherein the support frame mechanism includes a main support column and a main power wheel, the main support column is symmetrically arranged, the main power wheel is rotatably arranged at the lower end of the side wall of the main support column facing outward, and the retractable adjustable auxiliary support assembly is arranged on the front and rear walls of the main support column; the retractable adjustable auxiliary support assembly includes a first rotating rod, a second rotating rod, a sliding adjustment block and an auxiliary support mechanism, the first rotating rod is rotatably arranged at the lower end of the side wall of the main support column, the sliding adjustment block is embedded and slidably arranged on the side wall of the main support column, the second rotating rod is rotatably connected between the movable end of the first rotating rod and the sliding adjustment block, and the auxiliary support mechanism is arranged at the lower part of the movable end of the first rotating rod.

[0006] Further, the main power wheel is driven by a power motor, and the power motor is arranged in the main support column. The first protective bag is arranged on the opposite side walls of the main support column for protecting the patient's lower limbs. The main support column is provided with a storage groove on the side wall facing outward and on its front and rear side walls respectively. The front and rear side walls of the main support column are provided with adjustment grooves. The storage grooves on the front and rear side walls of the main support column are respectively arranged on the side of the adjustment groove close to the main power wheel. The inner side wall of the adjustment groove is provided with a linear array of clamping grooves. The upper end of the main support column is provided with a sliding groove, and the sliding groove is arranged on the inner side of the adjustment groove and the storage groove. Furthermore, a blocking block is obliquely provided at the upper end of the storage groove, an expanding airbag is embedded on the inner wall of the storage groove close to the sliding groove, a folding groove is provided at the lower part of the storage groove that does not penetrate the main support column, a storage electromagnetic block is embedded in the bottom of the folding groove, a pushing magnetic block is slidably provided in the folding groove, and the pushing magnetic block is arranged opposite to the storage electromagnetic block.

[0007] Further, the sliding adjustment block is slidably arranged in the adjustment groove, a pressing block is slidably embedded in the upper part of the sliding adjustment block, a guide block is connected to the lower end of the pressing block, the guide block is arranged in a triangular prism shape, the guide block is movably arranged inside the sliding adjustment block, a restoring spring is connected between the lower end of the guide block and the sliding adjustment block, and a locking block is symmetrically embedded and slidably arranged on both side walls of the sliding adjustment block, the locking block is arranged in a trapezoidal column shape, the locking block is movably engaged in the locking groove, and the inclined surfaces of the symmetrical locking blocks are slidably connected to the inclined surfaces of the guide blocks respectively; During use, hold the sliding adjustment block and press the push block. The guiding block moves downward, restoring the compression of the recovery spring. As the guiding block moves downward, the inclined surfaces of the clamping blocks are in sliding contact with the inclined surface of the guiding block, causing the symmetric clamping blocks to move inward and slide into the sliding adjustment block, disengaging the clamping blocks from the restriction of the clamping grooves. Then, release the hand after sliding the sliding adjustment block up and down in the adjustment groove to select a suitable position. Under the elastic action of the recovery spring, the guiding block moves upward, pushing the symmetric clamping blocks to slide back into the clamping grooves for positioning. The first rotating rod, the second rotating rod, and the main support column form a stable triangular support to provide comprehensive support for the patient and prevent the patient from falling. When the retractable adjustment type auxiliary support component is not needed, the sliding adjustment block can be pulled to the upper end of the adjustment groove for fixation, so that the first rotating rod and the second rotating rod are attached to the side wall of the main support column, which is convenient for storage and reduces the floor area.

[0008] Further, the auxiliary support mechanism includes an auxiliary electromagnetic block, a rotating shaft, an auxiliary wheel, a conversion magnetic plate, and a conversion gripper. The rotating shaft is rotatably connected to the lower part of the movable end of the first rotating rod. The auxiliary electromagnetic block is sleeved on the upper end of the rotating shaft. The auxiliary wheel is rotatably arranged at the lower end of the rotating shaft. The conversion magnetic plate is slidably sleeved on the rotating shaft. The conversion magnetic plate is arranged opposite to the auxiliary electromagnetic block. Elastic ropes are connected to both ends of the conversion magnetic plate and the auxiliary electromagnetic block. In the initial state, under the elastic pull of the elastic ropes, the conversion magnetic plate is in contact with the auxiliary electromagnetic block. The conversion grippers are symmetrically rotatably arranged at both ends of the rotating shaft. The conversion grippers are symmetrically arranged on both sides of the auxiliary wheel. When the symmetric conversion grippers are closed, they can cover and clamp the auxiliary wheel. The conversion gripper is in a U shape, and the right-angle end of the upper part of the conversion gripper is slidably connected to the lower wall of the conversion magnetic plate. The relative position between the unidirectional symmetric auxiliary wheel and the driving wheel forms a triangular area, further increasing the stability of the device during movement and reducing the risk of tipping over. When walking on a sloping ground, the angles between the front and rear auxiliary wheels and the main power wheel can be adjusted according to the slope of the ground, so that the device can adapt to the slope of the ground and keep it in a vertical state as much as possible to avoid the risk of the patient falling due to the angle between the device and the ground being too large. In the initial state, under the elastic pull of the elastic rope, the conversion magnetic plate fits with the auxiliary electromagnetic block, and the conversion magnetic plate pulls the conversion clamp to open the symmetrical conversion clamp without affecting the operation of the auxiliary wheel. When the patient is in use, the power motor is controlled by the switch to make the main power wheel move forward or backward. When the patient stops moving, the main power wheel is controlled to stop, thereby making the auxiliary wheel move backward. The auxiliary wheel stops, but the roller structure is prone to sliding under the action of inertia. At this time, the auxiliary electromagnetic block is energized to generate magnetism. The auxiliary electromagnetic block and the conversion magnetic plate are set with the same pole. Under the action of magnetic repulsion, the conversion magnetic plate moves down to press the symmetrical conversion clamps. The conversion clamps rotate relative to each other on both sides of the rotating shaft, thereby clamping and covering the auxiliary wheel. The electromagnetic principle is combined with the clamping structure to achieve rapid conversion of the auxiliary wheel between the rotating state and the emergency stop state, and the lower end face of the conversion clamp contacts the ground, which indirectly increases the ground contact area of ​​the auxiliary wheel, increases the friction with the ground, increases the stability of the device, and reduces the risk of patients falling.

[0009] Further, the first anti-dumping bracket mechanism is arranged in a receiving groove facing outwards of the main support column, and the second anti-dumping bracket mechanism is symmetrically arranged in the receiving grooves on the front and rear side walls of the main support column, and the first anti-dumping bracket mechanism and the second anti-dumping bracket mechanism have the same structure; Further, the first anti-dumping bracket mechanism includes a support rod, a sliding rod and a spreading support rod, the support rod is rotatably arranged on the upper inner wall of the storage groove, the support rod rotates toward the outside of the storage groove, the side wall of the support rod is in contact with the spread airbag, the sliding rod is arranged at the lower end of the support rod, the sliding rod is movably arranged in the storage groove, a sliding ring is slidably sleeved on the sliding rod, the spreading support rod is rotatably arranged on the sliding ring in a circular array, the spreading support rod is slidably arranged in the gathering groove and the storage groove, a torsion spring is connected between the spreading support rod and the sliding ring, the connection between the sliding ring and the spreading support rod is covered with a top plate, in the initial state, the torsion spring is in a compressed state, and the lower end of the spreading support rod is in contact with the pushing magnetic block; When the whole device tilts to the side, the storage electromagnetic block is energized to generate magnetism. The storage electromagnetic block and the pushing magnetic block have different magnetic poles. The pushing magnetic block moves up in the gathering groove under the action of magnetic repulsion, and then pushes the spreading strut to slide and move up on the sliding rod. When the spreading strut moves out of the gathering groove, that is, when the magnetic block is pushed to the highest point, the air pump works, the airbag is inflated and explodes, the support rod is pushed out of the storage groove and supported on the blocking block, and the spreading struts of the circular array are spread out under the elastic action of the torsion spring to form multiple groups of support leg structures and support on the top plate. When the device tilts sideways, the spreading struts of the support leg structure contact the ground, and the sliding ring moves up to support the support rod, thereby supporting the device, quickly stabilizing the center of gravity of the device, and preventing the device from completely tipping over and causing the patient to fall to the ground; when the whole device tilts forward or backward, similarly, the second anti-tipping bracket mechanism pops out to support and help the device stabilize the center of gravity.

At this time, the head protection plate forms a seat for the patient to rest.

[0011] Furthermore, the waist protection mechanism includes a waist protection frame, an induction belt and a rotating handle.

A switch is provided on the rotating handle, and the switch is electrically connected to the power motor. The induction belt is connected to the inner side of the waist protection frame through a connecting belt. The connecting belt is made of polyester fabric, which is soft and inelastic.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention provides an anti-fall protection device for nursing osteoporosis patients. The invention uses the electromagnetic principle in combination with a snap-fit ​​connection structure to set a retractable and adjustable auxiliary support assembly. The first rotating rod, the second rotating rod and the main support column form a stable triangular support to provide all-round support for the patient and prevent the patient from falling. The relative positions of the unilaterally symmetrical auxiliary wheels and the main power wheels form a triangular area, which further increases the stability of the device and reduces the risk of rollover. While providing stable auxiliary support, the device can be adaptively adjusted according to the slope of the road section. The auxiliary wheel can be quickly converted between the rotating state and the emergency stop state through the setting of the conversion gripper. The lower end surface of the conversion gripper contacts the ground, which indirectly increases the ground contact area of ​​the auxiliary wheel, increases the friction with the ground, increases the stability of the device, and reduces the risk of the patient falling. When the retractable and adjustable auxiliary support assembly is not needed, the sliding adjustment block can be pulled to the upper end of the adjustment slot and fixed, so that the first rotating rod and the second rotating rod are attached to the side wall of the main support column, which is convenient for storage and reduces the floor space.

[0014] 2. The first anti-dumping bracket mechanism and the second anti-dumping bracket mechanism are set by combining the pre-action principle with the electromagnetic principle. When the patient is about to fall, when the device is about to fall, the spread support rods of the support leg structure are promptly popped out to contact the ground, thereby supporting the device from different directions, quickly stabilizing the center of gravity of the device, helping the patient to regain the center of gravity, and preventing the device from completely tipping over and causing the patient to fall to the ground. When the patient has no tendency to fall, the first anti-dumping bracket mechanism and the second anti-dumping bracket mechanism do not work; 3. The head protection board can protect the patient's head in time whether the patient falls sideways, forward or backward, and dynamically protect the patient's head without affecting the patient's vision. When the patient is tired, it can also serve as a seat for rest, with a variety of uses; 4. The device can be adaptively adjusted according to the patient's height. The inelastic connecting belt enables the induction belt to provide certain support for the patient, connecting the patient to the waist protection frame. On the one hand, it helps the patient to stabilize the center of gravity when he is about to fall, preventing the patient from falling off the device. On the other hand, it supports the part above the patient's waist. The patient holds the handle with his hand to correct the patient's walking posture and help the patient stabilize his body.

Under the elastic action of the restoring spring 234, the guide block 232 moves upward, pushing the symmetrical locking block 233 to slide into the locking groove 17 again for positioning, and the first rotating rod 21, the second rotating rod 22 and the main support column 11 form a stable triangular support, providing all-round support for the patient to prevent the patient from falling; for patients with mild symptoms, if there is no need to use the retractable adjustable auxiliary support assembly 2, the sliding adjustment block 23 can be pulled to the upper end of the adjustment groove 16 and fixed, so that the first rotating rod 21 and the second rotating rod 22 are attached to the side wall of the main support column 11, which is convenient for storage and reduces the floor space; When walking on flat ground, adjust the position of the sliding adjustment block 23 so that the first rotating rod 21 is in a horizontal state, the auxiliary wheel 243 touches the ground, and the main power wheel 12 and the auxiliary wheels 243 on both sides support each other during operation; when walking on a sloped ground, the angles between the front and rear two sets of auxiliary wheels 243 and the main power wheel 12 can be adjusted according to the slope of the ground, so that the device can adapt to the slope of the ground, maintain a vertical state as much as possible, maintain the correction of the patient's body shape, help the patient to maintain an upright state, and avoid the angle between the device and the ground is too large to increase the risk of the patient falling.

[0026] According to the height of the patient, the extension length of the sliding bracket 51 is adjusted by the positioning bolt 57 so that the head protection plate 54 is at the position of the patient's head, and then the waist protection frame 61 is adjusted by the protection bolt 62 so that the waist protection frame 61 is at the patient's waist position, and the rotating handle 63 is turned upward to let the patient stand on the inside of the waist protection frame 61, and the rotating handle 63 is turned back to wear the sensing belt 64 on the patient's waist. The inelastic connecting belt 66 enables the sensing belt 64 to support the patient to a certain extent, and connects the patient to the waist protection frame 61. On the one hand, it helps the patient to stabilize the center of gravity when the patient is about to fall, and prevents the patient from falling off the device. On the other hand, it supports the patient's body above the waist. The patient holds the rotating handle 63 with his hand to correct the patient's walking posture and help the patient stabilize his body shape. Turn on the main controller to make the device move with the patient.

[0027] In the initial state, the head protection plate 54 is located at the back of the patient's head. Under the elastic pulling of the elastic rope 246, the conversion magnetic plate 244 fits with the auxiliary electromagnetic block 241, and the conversion magnetic plate 244 pulls the conversion clamp 245 to open the symmetrical conversion clamp 245 without affecting the operation of the auxiliary wheel 243. When the patient walks, the power motor is controlled by the switch to make the main power wheel 12 move forward or backward to follow the patient. When the patient stops moving, the main power wheel 12 is controlled to stop, and then the auxiliary wheel 243 stops. However, the roller structure is prone to sliding under the action of inertia. At this time, the auxiliary electromagnetic block 241 is turned on. Electricity generates magnetism, and the auxiliary electromagnetic block 241 and the conversion magnetic plate 244 are arranged with the same pole. Under the action of magnetic repulsion, the conversion magnetic plate 244 moves downward to press the symmetrical conversion clamp 245, and the conversion clamp 245 rotates relatively on both sides of the rotating shaft 242, thereby clamping and covering the auxiliary wheel 243; the electromagnetic principle is combined with the clamping structure to realize the rapid conversion of the auxiliary wheel 243 between the rotating state and the emergency stop state, and the lower end surface of the conversion clamp 245 contacts the ground, which indirectly increases the ground contact area of ​​the auxiliary wheel 243, increases the friction with the ground, increases the stability of the device, and reduces the risk of patients falling.

[0028] When the patient is about to fall sideways, the whole device tilts to the side. At this time, the acceleration sensor 65 senses the changes in the patient's body, determines that the patient is about to fall sideways, and sends a signal to the main controller. The main controller immediately operates the first anti-tilt bracket mechanism 3, so that the storage electromagnetic block 142 is energized to generate magnetism. The storage electromagnetic block 142 and the pushing magnetic block 143 are arranged with different magnetic poles. The pushing magnetic block 143 moves up in the gathering groove 141 under the action of the magnetic repulsion force, and then pushes the spreading strut 34 to slide up on the sliding rod 32. When the spreading strut 34 moves out of the gathering groove 141, that is, pushes the magnetic block 143 to move up to the highest point, the air pump works, and the airbag 19 is inflated and exploded. The support rod 31 is pushed out of the storage slot 14 and rests on the blocking block 15, and the scattered support rods 34 of the circumferential array are spread out under the elastic action of the torsion spring to form multiple groups of support leg structures and rest on the top plate 35. At the same time, the third protective bag 55 is inflated to protect the patient's head, the second protective bag 67 is inflated to protect the patient's waist, and the first protective bag 18 is inflated to protect the patient's lower limbs. When the device is tilted sideways, the scattered support rods 34 of the support leg structure contact the ground, and the sliding ring 33 moves up to rest on the support rod 31, thereby supporting the device and quickly stabilizing the center of gravity of the device. The induction belt 64 pulls the patient's waist to help the patient regain the center of gravity, thereby preventing the device from completely tipping over and causing the patient to fall to the ground. When the patient is about to fall backwards, similarly, the main controller operates the second anti-dumping support mechanism 4 on the rear side, and at the same time makes the air pumps corresponding to the first protective bag 18, the second protective bag 67 and the third protective bag 55 work simultaneously, so that they are inflated to protect the patient's lower limbs, waist and head respectively; when the patient is about to fall forward, similarly, the main controller operates the second anti-dumping support mechanism 4 on the front side, and at the same time starts the flipping motor 52, so that the head protection plate 54 flips forward from above the patient's head, and the first protective bag 18, the second protective bag 67 and the third protective bag 55 are inflated to protect the patient's lower limbs, waist and head respectively; after use, the air pump is used to recycle the expanded airbags 19, the first protective bag 18, the second protective bag 67 and the third protective bag 55 again, the storage electromagnetic block 142 is powered off and loses its magnetism, and the magnetic block 143 is pushed down, and the scattered support rods 34 of the circular array are folded and inserted into the folding groove 141.

[0029] When the patient is tired and needs to rest, he unfastens the induction belt 64, completely loosens the positioning bolts 57 and the protective bolts 62, moves the sliding bracket 51 downward and slides into the sliding groove 13, controls the flipping motor 52 to rotate the head protection plate 54 downward, and flips the head protection plate 54 to the inner side of the waist protection frame 61. At this time, the head protection plate 54 forms a seat for the patient to rest.

[0030] It is worth mentioning that the device mainly supports the patient through the sensing belt 64 and the rotating handle 63 and assists in correcting the patient's posture when walking and standing, preventing the patient and the device from tipping over while the patient is moving; the operation settings of the controller, the application of the air pump and the acceleration sensor 65 are all existing technologies and will not be repeated here.

[0031] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
