Description

Technical Field

[0001] This utility model relates to the field of walking care equipment technology, and more specifically to a fall-proof auxiliary walking care device. Background Technology

[0002] Neurosurgical patients may experience decreased balance and coordination due to damage to their nervous system, increasing their risk of falls. Walking aids can provide additional support and stability, helping patients with leg strength training, balance training, or coordination training, reducing the likelihood of falls and minimizing secondary injuries caused by falls.

[0003] Currently, the assistive walking devices used in hospital clinics, such as the rehabilitation walking assistive device with prior art publication number CN221617797U, can provide support for patients during walking training. However, because neurosurgical patients have relatively weak leg strength, the device is prone to spontaneous rotation after being bumped by people or objects around them, causing the patient to move passively with the device. This can easily lead to the patient falling and affect the safety of patient walking care. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fall-prevention assistive walking care device. By using infrared distance sensors installed around the handrail to detect the distance of people around, the device can automatically control the brake block to insert into the brake groove to stop the wheel from rotating when the distance is too close. This can prevent patients from falling due to collisions with people around them during walking training, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall-proof auxiliary walking care device, including a handrail, with two brake wheels arranged side by side at the bottom of the handrail, and an extension rod at the bottom of the handrail for adjusting the height of the handrail and the extension length of the brake wheels, so as to suit patients of different heights;

[0006] A curved rod is fixed to the bottom of the handrail, and three infrared ranging sensors are provided between the handrail and the curved rod. The three infrared ranging sensors are respectively located on the front side and the left and right sides of the handrail to monitor the distance between people and the handrail in different directions around the handrail.

[0007] Each brake wheel includes a wheel frame with a wheel at the bottom and a brake assembly at the top. The brake assembly is installed inside the wheel frame. When the infrared ranging sensor detects that a person is close to the handrail, it automatically activates the brake assembly to stop the wheel from rotating.

[0008] In a preferred embodiment, the brake assembly includes a plurality of brake grooves formed in the middle of the top of the wheel. The plurality of brake grooves are evenly distributed in a circular array with the center of the wheel as the center. A brake block is provided on the top of the brake groove. The top of the brake block is inserted into the wheel frame. Two springs are fixed on both sides of the top of the brake block. A telescopic rod is provided inside the outer spring. The top of the spring is fixed to the inside of the wheel frame.

[0009] An iron rod is fixed to the top center of the brake block, and multiple springs are respectively located on both sides of the iron rod. An electromagnet is located on the top of each spring. The electromagnet is fixed to the top of the inside of the wheel frame. When the electromagnet is energized, it attracts the iron rod and fixes the brake block to the top of the wheel. When the infrared ranging sensor detects that the distance between a person and the handrail is close, the electromagnet is de-energized, allowing the compressed spring to push the brake block into the brake groove opened on the outer wall of the wheel to prevent the wheel from rotating.

[0010] In a preferred embodiment, a baffle is provided on the outside of the wheel, and the baffle is fixed to the bottom of the wheel frame.

[0011] In a preferred embodiment, a controller for receiving monitoring signals from an infrared ranging sensor is provided between the handrail and the curved bar, and the controller controls the electromagnet to be powered on and off.

[0012] In a preferred embodiment, the extension rod includes two connecting rods, each with a vertical extension rod inserted at its top end. The top end of the vertical extension rod is fixed to the bottom end of the handrail, and a horizontal extension rod is inserted at the bottom end of the vertical extension rod. The end of the horizontal extension rod away from the vertical extension rod is fixed to one end of the wheel frame.

[0013] In a preferred embodiment, the vertical extension rod and the connecting rod, as well as the horizontal extension rod and the connecting rod, are fixed together by bolt fasteners, which consist of bolts and nuts. The vertical extension rod and the horizontal extension rod are provided with multiple through holes for the bolt fasteners to pass through.

[0014] In a preferred embodiment, the connecting rod is L-shaped, and a rotatable auxiliary wheel is fixed to the bottom end of the connecting rod on the side away from the horizontal extension rod.

[0015] In a preferred embodiment, the outer end of the bent rod is detachably fitted with a detachable cloth strap for the patient to sit on.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By using infrared distance sensors installed around the handrail to detect the distance to people in the vicinity, and automatically controlling the brake block to insert into the brake groove to stop the wheels from turning when the distance is too close, the system can prevent patients from falling due to collisions with people in the vicinity during walking training, thereby improving the safety of patients during walking training.

[0018] 2. By pulling up and down the vertical extension rods and pulling left and right the horizontal extension rods, the height of the handrail and the distance between the wheels and the handrail can be adjusted, thereby making this utility model suitable for patients of different heights and expanding the scope of application of this utility model.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Refer to the instruction manual appendix Figure 1 This utility model provides a fall-proof auxiliary walking care device, including a handrail 1, with two brake wheels 4 arranged side by side at the bottom of the handrail 1, and an extension rod 2 at the bottom of the handrail 1 for adjusting the height of the handrail 1 and the extension length of the brake wheels 4, so as to be suitable for patients of different heights in neurosurgery.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the extension rod 2 includes two connecting rods 21, which are L-shaped. A rotatable auxiliary wheel 3 is fixed to the bottom end of the connecting rod 21 away from the horizontal extension rod 23. The bottom end of the auxiliary wheel 3 and the bottom end of the brake wheel 4 are both above the ground to maintain balance and facilitate the movement of this utility model on the ground.

[0032] Both connecting rods 21 have vertical extension rods 22 inserted at their top ends. The top ends of the vertical extension rods 22 are fixed to the bottom ends of the handrail 1, and the bottom ends of the vertical extension rods 22 are inserted to the horizontal extension rods 23. Furthermore, the vertical extension rods 22 and connecting rods 21, and the horizontal extension rods 23 and connecting rods 21 are all fixed with bolts 24. Both the vertical extension rods 22 and the horizontal extension rods 23 have multiple through holes for the bolts 24 to pass through. For patients of different body types with different leg lengths, the height of the handrail 1 can be adjusted by loosening the bolts 24 and moving the vertical extension rods 22 up or down. The distance between the brake wheel 4 and the connecting rods 21 can be adjusted by moving the horizontal extension rods 23 outward or inward. This allows the invention to be used for patients with different leg lengths, thus expanding the scope of application of this invention.

[0033] For some patients who are unable to stand independently, they are prone to falling due to accidental collisions with people around them during walking training because of the weakness in their legs. In order to improve the safety of patients during walking training, this utility model has a curved rod 7 fixed at the bottom of the handrail 1. Three infrared distance sensors 5 are provided between the handrail 1 and the curved rod 7. The three infrared distance sensors 5 are respectively located on the front side and the left and right sides of the handrail 1 to monitor the distance between people around the handrail 1 and the handrail 1 in different directions.

[0034] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, each brake wheel 4 includes a wheel frame 41. The end of the horizontal extension rod 23 away from the vertical extension rod 22 is fixed to one end of the wheel frame 41. A wheel 43 is provided at the bottom of the wheel frame 41. A baffle 42 is provided on the outside of the wheel 43. The baffle 42 is fixed to the bottom of the wheel frame 41. The baffle 42 can cover the wheel 43 to achieve the effect of dust prevention. A brake assembly 44 is provided at the top of the wheel 43. The brake assembly 44 is installed inside the wheel frame 41. The brake assembly 44 can stop the wheel 43 from continuing to rotate and brake it.

[0035] Furthermore, the specific structure of the brake assembly 44 is as follows: Figure 5 and Figure 6 As shown, the wheel 43 has multiple brake grooves 441 located in the middle of its top. These grooves are evenly distributed in a circular array around the center of the wheel 43. Each brake groove 441 has a brake block 442 on its top. The top of each brake block 442 is inserted into the wheel frame 41. Springs 443 are fixed to both sides of the top of each brake block 442. A telescopic rod 446 is located inside the outer spring 443. The top of the telescopic rod 446 is fixed to the top of the wheel frame 41, and the bottom of the telescopic rod 446 is fixed to the bottom of the brake block 442. The top of each spring 443 is fixed to the inside of the wheel frame 41. An iron rod 445 is fixed to the middle of the top of each brake block 442. Multiple springs 443 are located on both sides of the iron rod 445. An electromagnet 444 is located on the top of each spring 443 and is fixed to the top of the wheel frame 41.

[0036] A controller 6 is provided between the handrail 1 and the curved bar 7 to receive the monitoring signal from the infrared ranging sensor 5. The controller 6 controls the electromagnet 444 to turn on and off. Medical staff can also set the safe distance between people and objects around them and the handrail 1 through the controller 6. Once the distance is too close and exceeds the safe distance, the electromagnet 444 will be de-energized and braked.

[0037] The specific steps are as follows:

[0038] When using this utility model for daily training, first adjust the height of the armrest 1, then adjust the position of the wheel 43, and then the patient holds the armrest 1 with both hands. As the patient exerts force with both hands, the armrest 1 is pushed to make the wheel 43 and the auxiliary wheel 3 rotate on the ground, so that the patient's legs can passively walk while the wheel 43 is rotating, so as to achieve the effect of walking training.

[0039] When a person or object gets too close to the handrail 1, in order to prevent a collision between the person or object and the handrail 1, the infrared ranging sensor 5 uses infrared technology to measure the distance between the person / object and the handrail 1. When the distance is detected to be too close, the infrared ranging sensor 5 sends the detected signal to the controller 6, and the controller 6 controls the electromagnet 444 to be de-energized, so that the compressed spring 443 can push the brake block 442 to insert into the brake groove 441 opened on the outer wall of the wheel 43, and extend the telescopic rod 446 to stop the wheel 43 from rotating, so as to prevent accidental collisions that cause the patient to fall due to forced movement of the present invention, thereby improving the safety of the present invention during use.

[0040] Conversely, when the infrared ranging sensor 5 does not detect that the distance between the person or object in the vicinity and the handrail 1 is too close, the controller 6 controls the electromagnet 444 to charge, so that the electromagnet 444 is energized and attracts the iron rod 445 to fix the brake block 442 to the top of the wheel 43, ensuring that the wheel 43 can rotate normally, so as to facilitate the patient's walking training.

[0041] In addition, this utility model allows for the option of attaching the detachable cloth strip 8 to the curved rod 7, depending on the patient's specific condition. Figure 7 As shown, for some patients who are completely unable to stand, they can choose to sit on the detachable cloth strap 8 for training; for patients with milder conditions, the detachable cloth strap 8 can be removed and the present invention can be used for training in a standing position. The connection between the detachable cloth strap 8 and the curved rod 7 can be achieved through structures such as Velcro and zippers. This technology is a mature technical solution in the prior art, and this application does not impose further limitations on it.

[0042] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
