Description

Technical Field

[0001] This utility model relates to the field of wheelchairs, and more specifically, to an easily adjustable neurological care wheelchair. Background Technology

[0002] Neurological patients often experience mobility issues, poor balance, and muscle weakness due to their illness, placing high demands on the comfort, safety, and practicality of nursing wheelchairs. However, currently available neurological nursing wheelchairs on the market have significant shortcomings in several aspects, failing to meet the actual needs of patients and caregivers.

[0003] Most existing nursing wheelchairs have fixed armrests, leg rests, and footrests, making them unsuitable for personalized adjustments based on patient height, body type, and usage scenarios. For taller or shorter patients, fixed-height armrests may prevent arms from relaxing naturally, leading to fatigue and soreness after prolonged use. The leg rests and footrests cannot be fine-tuned, hindering leg extension and compromising comfort. Some existing wheelchairs lack adequate anti-tipping mechanisms. When accelerating, going uphill, downhill, or encountering bumps, the wheelchair is prone to tipping backward or forward due to changes in the patient's center of gravity. A tipping could result in serious injuries such as fractures or head injuries. Furthermore, traditional wheelchairs often have inadequate anti-slip handles, causing caregivers to slip, especially with wet or sweaty hands, making stable control difficult and increasing safety risks. Therefore, we have developed an adjustable neurology nursing wheelchair to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned purpose, this utility model provides the following technical solution: an easily adjustable neurological nursing wheelchair, including a main wheelchair frame, a wheelchair cushion bolted to the top of the main wheelchair frame, a seat plate installed under the bottom plate of the seat cushion, an X-shaped seat support below the rear plate of the seat plate, a wheelchair backrest bolted to the slotted end of the rear of the wheelchair cushion, wheelchair push handles connected to the top two sides of the wheelchair backrest, and anti-slip sleeves nested on the outer surface of the wheelchair push handles.

[0005] As a preferred technical solution of this utility model, the wheelchair seat cushion is fixed with mounting vertical plates on both sides, and the wheelchair protective side plates are fixed with bolts on the inner plate of the mounting vertical plates.

[0006] As a preferred technical solution of this utility model, a base frame is provided below the main support of the wheelchair, and the bottom end of the X-shaped support of the seat cushion is connected to the base frame.

[0007] As a preferred technical solution of this utility model, the two sides of the base frame are fixed with arm support lifting adjustment rods, the outer surface of the arm support lifting adjustment rods is nested with a fixing ring, and the fixing ring is connected to the outer plate of the mounting vertical plate. The top of the arm support lifting adjustment rods is equipped with a wheelchair arm support.

[0008] As a preferred technical solution of this utility model, a powered rear wheel is installed on the two rotating shafts at the rear of the base frame, a rear wheel auxiliary motor is installed on the power connection part of the powered rear wheel, and anti-tilt brackets are respectively provided on both sides of the rear wheel auxiliary motor, and an anti-tilt support rod is connected to the bottom end of the anti-tilt bracket.

[0009] As a preferred technical solution of this utility model, the front end of the base frame is provided with an arc-shaped bracket, which is mirror-shaped with the anti-backward tilting bracket, and an anti-forward tilting arc-shaped plate is provided on the outer edge of the bottom of the arc-shaped bracket.

[0010] As a preferred technical solution of this utility model, omnidirectional wheels are installed on the two rotating shafts at the front end of the base frame.

[0011] As a preferred technical solution of this utility model, the front end of the wheelchair seat is provided with a bracket body, a leg support is fixed between the two rods of the bracket body, and a footrest is connected below the leg support.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The height of the wheelchair armrest can be adjusted using the armrest height adjustment lever. Users of different heights and body types, or in different usage scenarios, can adjust the armrest to the most comfortable height, allowing the user's arms to receive natural and relaxed support, effectively reducing arm fatigue during long periods of sitting.

[0013] The leg rests and footrests can be finely adjusted to accommodate the user's leg length and posture, ensuring natural leg extension and greatly improving lower limb comfort when using a wheelchair. The wheelchair backrest is secured to the rear of the seat via bolts at the slot end, providing stable support that conforms to the curve of the user's back, reducing back pressure. This is particularly suitable for neurology patients who may experience weakness or difficulty maintaining posture.

[0014] The X-shaped support connecting the seat cushion to the base frame creates a design that evenly distributes pressure, making the user more stable and comfortable while seated, reducing discomfort caused by localized pressure. Wheelchair safety side panels on both sides of the seat cushion, mounted on the vertical mounting plate, effectively prevent the user from sliding to the sides during use, significantly reducing the risk of accidental falls, especially for neurology patients with poor balance.

[0015] With anti-tilt brackets on both sides of the rear wheels and anti-tilt struts connected to the bottom, the anti-tilt struts will contact the ground in time to provide support when the user's body tilts backward due to acceleration, going uphill, or encountering bumps, preventing the wheelchair from tipping over and ensuring the user's safety. The anti-forward tilting arc plate at the bottom of the arc-shaped bracket at the front of the base frame plays a role when the wheelchair is going downhill, decelerating, or encountering obstacles that may cause it to tilt forward. It contacts the ground to provide cushioning and support, preventing the wheelchair from tipping forward and providing double safety protection for the user.

[0016] The anti-slip sleeves nested on the outer surface of the wheelchair handles increase friction between the caregiver's hands and the handles, effectively preventing slippage even when hands are wet or sweaty. This ensures the caregiver can stably control the wheelchair and avoids the danger of loss of control due to slipping hands. The powered rear wheels are equipped with a rear-wheel auxiliary motor. During long-distance travel or uphill situations, the motor's power reduces the burden on the caregiver, improving mobility and making patient transfers easier.

[0017] The swivel wheels on both sides of the front of the base frame can rotate flexibly in all directions, allowing caregivers to easily change the direction of travel when pushing the wheelchair. This facilitates maneuvering in narrow passageways and wards, improving the wheelchair's operability and range of use. The main frame, base frame, and other components are connected by bolts and slots, resulting in a robust structure capable of withstanding a certain weight and external impacts. This ensures the wheelchair's reliability during long-term use and reduces maintenance costs and safety hazards caused by loose or damaged parts. Attached Figure Description

A wheelchair armrest 13 is installed at the top of the armrest lifting adjustment rods 11.

[0023] The base frame 10 has two rotating shafts at its rear end, each mounting a powered rear wheel 14. A rear wheel auxiliary motor 15 is mounted on the power connection of the powered rear wheel 14. Anti-tilt brackets 16 are mounted on both sides of the rear wheel auxiliary motor 15, and anti-tilt support rods 17 are connected to the bottom of each anti-tilt bracket 16. An arc-shaped bracket 18 is located at the front end of the base frame 10, mirroring the anti-tilt bracket 16. An anti-forward-tilting arc-shaped plate 19 is mounted on the outer edge of the bottom of the arc-shaped bracket 18.

[0024] The front two sides of the base frame 10 are equipped with swivel wheels 20. The front of the wheelchair seat 2 is provided with a bracket body 21, and a leg support 22 is fixed between the two rods of the bracket body 21. The footrest 23 is connected to the bottom of the leg support 22.

[0025] The working principle of the easily adjustable neurology nursing wheelchair: The main frame 1 is the basic support structure of the entire wheelchair, providing the foundation for the installation and support of all components. The wheelchair seat 2 is bolted to the main frame 1. The seat plate 3 is installed under the bottom plate of the seat 2, and the X-shaped bracket 4 connects the bottom of the seat plate 3 to the base frame 10. This X-shaped bracket structure can evenly distribute the pressure on the main frame 1 and the base frame 10 when bearing the weight of the user, improving the stability and load-bearing capacity of the seat 2, and also enhancing the overall structural strength of the wheelchair. The backrest 5 is bolted to the rear of the seat 2, providing back support for the user. The wheelchair handles 6 are connected to the top two sides of the backrest 5. The anti-slip sleeves 7 nested on the outer surface of the handles increase friction, making it easier for caregivers to push the wheelchair and preventing hand slippage during pushing.

[0026] The mounting vertical plates 8 on both sides of the wheelchair seat cushion 2 provide a mounting base for the wheelchair protective side plates 9. The wheelchair protective side plates 9 are bolted to the inner plate of the mounting vertical plates 8, which can prevent the user's body from sliding to the sides when riding the wheelchair, thus protecting the user's safety.

[0027] The armrest adjustment rods 11 on both sides of the base frame 10 allow for height adjustment of the wheelchair armrest 13. Fixing rings 12 are nested on the outer surface of the armrest adjustment rods 11 and connected to the outer plate of the mounting vertical plate 8, serving both fixing and guiding functions. Caregivers can adjust the armrest adjustment rods 11 to change the height of the wheelchair armrest 13 according to the user's needs, adapting to different users' physical conditions and usage habits.

[0028] The powered rear wheels 14 are mounted on both sides of the rear of the base frame 10 via a pivot, and the rear wheel auxiliary motor 15 is mounted on the power connection part of the powered rear wheels 14. When the rear wheel auxiliary motor 15 is started, the motor outputs power, which is transmitted to the powered rear wheels 14 through the power connection part, causing the powered rear wheels 14 to rotate, thereby driving the wheelchair forward or backward. This power drive method can reduce the burden on caregivers pushing the wheelchair, especially when moving long distances or encountering uphill situations.

[0029] The anti-tilt bracket 16 is installed on both sides of the powered rear wheel 14, and its bottom end is connected to the anti-tilt support rod 17. When the wheelchair is in motion, especially when accelerating, going uphill or encountering bumps, the user's body may tilt backward.

[0030] The arc-shaped support 18 at the front end of the base frame 10 is mirror-shaped with the anti-backward tilt support 16. The anti-forward tilt arc-shaped plate 19 on the outer edge of the bottom of the arc-shaped support 18 can prevent the wheelchair from tipping forward when going downhill, slowing down, or encountering obstacles. When the wheelchair tends to tilt forward, the anti-forward tilt arc-shaped plate 19 will contact the ground, providing cushioning and support.

[0031] The omnidirectional front wheels 20 are mounted on both sides of the front end of the base frame 10 via pivots, allowing them to rotate flexibly in all directions. When a caregiver pushes the wheelchair, they can change direction by operating the wheelchair handle 6. The omnidirectional front wheels 20 can automatically adjust their steering according to the change in pushing direction, enabling the wheelchair to turn flexibly and avoid obstacles.

[0032] The bracket 21 at the front end of the wheelchair seat 2 provides mounting support for the leg rest 22. The leg rest 22 is fixed between the two rods of the bracket 21 to support the user's legs. The footrest 23 is connected to the lower part of the leg rest 22, providing a place and support for the user's feet, so that the user can maintain a comfortable leg posture when riding the wheelchair.

[0033] Example 2: An adjustable neurological care wheelchair. A neurology ward admitted a patient with limited mobility due to a brain disease.

[0037] Wheel and auxiliary device installation: Powered rear wheels 14 are mounted on both sides of the rear of the base frame 10 via pivots and connected to rear wheel auxiliary motors 15 to provide power support for the wheelchair. Swivel-type front wheels 20 are installed on both sides of the front of the base frame 10 to facilitate wheelchair steering. Anti-backward tilt brackets 16, anti-backward tilt struts 17, arc-shaped brackets 18, and anti-forward tilt arc-shaped plates 19 are also installed to ensure patient safety.

[0038] Leg support installation: Install the support body 21 at the front end of the wheelchair seat 2, fix the leg support 22 between the two rods of the support body 21, and connect the footrest 23 to provide support for the patient's legs and feet.

[0039] The nurse assists the patient into the wheelchair and adjusts the height of the armrest 13 using the armrest adjustment lever 11, according to the patient's height and posture, so that the patient's arms can be comfortably placed on it. At the same time, the positions of the leg rest 22 and footrest 23 are adjusted so that the patient's legs can be naturally extended.

[0040] When the wheelchair needs to be moved, medical staff push it, and the pushing process is easier and less strenuous because the powered rear wheel 14 is equipped with a rear wheel auxiliary motor 15. When turning, the swivel front wheel 20 can steer flexibly, making it convenient for medical staff to operate.

[0041] During use, the anti-backward tilt bracket 16 and anti-backward tilt support 17 prevent the wheelchair from tilting backward, while the anti-forward tilt arc plate 19 prevents it from tilting forward, thus ensuring safety.

[0042] The workflow for an easily adjustable neurological care wheelchair is as follows: Check that all parts of the wheelchair are securely connected, including the bolt connections between the main frame 1 and the seat 2, and the slots and bolt connections between the backrest 5 and the seat 2, to ensure there are no loose parts.

[0043] Check that the anti-slip sleeve 7 is intact and properly fitted onto the wheelchair handle 6 to prevent hand slippage during pushing. Check that the rear wheel 14 and the swivel wheel 20 rotate smoothly without any jamming or abnormal noise. Confirm that the rear wheel auxiliary motor 15 has sufficient power and is functioning correctly.

[0044] Adjust the armrest lifting lever 11 according to the user's physical condition and needs to bring the wheelchair armrest 13 to a suitable height. By moving the armrest lifting lever 11 up and down and securing it with the retaining ring 12, ensure that the user's arm can be comfortably placed.

[0045] The positions of the leg rest 22 and footrest 23 can be finely adjusted to suit the user's leg length and placement habits, ensuring that the user's legs can stretch naturally and receive good support.

[0046] The caregiver assists the user to approach the wheelchair and parks it smoothly, ensuring that the swivel front wheels 20 and the powered rear wheels 14 are stationary. The caregiver guides the user to slowly sit on the wheelchair seat 2, with their back against the wheelchair backrest 5. The caregiver helps the user place their arms on the height-adjusted wheelchair armrests 13 to relax their arms.

[0047] The user places their legs on the leg rests 22 and their feet on the footrests 23 to further adjust their leg posture and ensure comfort. The caregiver holds the wheelchair handle 6 with anti-slip sleeves 7 and pushes the wheelchair forward, backward, or to turn as needed. When turning, the swivel front wheels 20 allow for easy change of direction.

[0048] When longer distances are required or when encountering uphill situations, the rear wheel auxiliary motor 15 can be activated. The motor transmits power to the powered rear wheels 14, propelling the wheelchair forward. Caregivers can control the pushing force and direction to achieve smooth movement in conjunction with the electric drive.

[0049] During movement, the wheelchair's protective side panels 9 prevent the user's body from sliding to the sides, ensuring user safety. If the wheelchair tends to tilt backward, the anti-tilt support 17 will contact the ground to provide support and prevent the wheelchair from tipping over; if it tilts forward, the anti-forward curved plate 19 will contact the ground to provide cushioning and support. Upon arrival at the destination and during the user's dismount phase, after arriving at the destination, the caregiver will smoothly park the wheelchair in a suitable position to ensure that the wheelchair will not slide or tip over.

[0050] The caregiver assists the user to slowly get up, first removing the legs from the leg rests 22 and footrests 23, then removing the arms from the wheelchair armrests 13, and then helping the user safely get off the wheelchair.

[0051] After use, clean the wheelchair, wiping down the seat cushion 2, backrest 5, armrests 13, and other parts. Regularly check the wear and tear of each component, such as the tires of the rear power wheel 14 and the swivel front wheel 20, and replace or repair them as needed.

[0052] Park the wheelchair in a dry, well-ventilated place. If storage is required, it can be folded according to its design features to save space.
