Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a portable walking booster device for elderly and weak patients. Background Art

[0002] As the global population ages, the number of frail elderly patients increases year by year, and their walking safety has become a focus of social attention. As the body functions of frail elderly patients gradually decline, their muscle strength weakens, and their joint flexibility decreases, they are prone to fatigue and even lose balance when walking, which increases the risk of falling. Falling may not only cause trauma such as fractures and abrasions, but also cause a series of complications, seriously affecting the quality of life and health of frail elderly patients.

[0003] Traditional walking assistance devices, such as crutches and walkers, can provide support and assistance to frail elderly patients to a certain extent, but their functions are relatively simple and lack intelligent and personalized design. These devices can usually only provide fixed support and cannot be adjusted in real time according to the patient's walking status and needs. In addition, traditional devices are also insufficient in rest function and upper limb strength training. Patients often need to find a resting place by themselves or rely on the assistance of others, and lack effective upper limb exercise methods.

[0004] Although there are many types of walking assistance devices on the market, most of them have the following shortcomings: First, there is a lack of real-time monitoring and intelligent response mechanisms, and it is impossible to accurately judge the patient's walking status and needs, and it is impossible to provide effective assistance in a timely manner; second, the auxiliary rest function is limited, and patients are prone to fatigue and discomfort during use. Patients often need to find a resting place by themselves or rely on the assistance of others; third, the overall design of the device is not compact and light enough, which is inconvenient to carry and move, bringing additional burden to patients.

[0005] In view of the above problems, the market is in urgent need of a portable walking assist device for elderly and frail patients that can monitor the patient's walking status in real time, provide intelligent response, and have an automatic adjustment rest function. Summary of the invention

[0006] To solve the above problems, the present invention provides a portable walking assist device for elderly and frail patients, which is used to monitor the patient's walking status in real time and provide timely assistance when the patient feels tired or loses balance, effectively reducing the risk of falling and ensuring the patient's walking safety.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a portable walking booster device for elderly weak patients, comprising a mounting frame, on which a monitoring module for real-time monitoring of the patient's walking state and an auxiliary component for the patient to rest are installed, the auxiliary component comprising a rest board, the mounting frame is a hollow structure, and a slide groove is provided on the mounting frame, the slide groove is a T-shaped structure, the rest board and the slide groove are slidably matched, a power piece is installed at one end of the slide groove, the output shaft of the power piece is connected to a first chain, the end of the first chain away from the power piece is fixedly connected to the bottom of the rest board, and a plurality of rollers are installed at the bottom of the rest board; The mounting frame is provided with a gripping assembly for exercising upper limb strength and an anti-tipping assembly for preventing patients from falling. The monitoring module signal is connected to the control module. The monitoring module includes an inclination sensor, a speed sensor and a pressure sensor. The inclination sensor and the speed sensor are both mounted on the mounting frame, and the pressure sensor is mounted on the gripping assembly. When the real-time speed data monitored by the speed sensor is lower than the threshold value in the control module, and the real-time pressure data monitored by the pressure sensor is greater than the threshold value in the control module, it means that the patient needs to rest, and the control module starts the power part and switches to the rest mode; When the real-time angle data monitored by the tilt sensor exceeds the threshold in the control module, it indicates that the patient has a tendency to fall, and the control module activates the anti-tipping component to adjust the tilt angle.

[0008] The technical principle of the above scheme is as follows: The patient's walking state, including walking speed, body tilt angle and upper limb grip strength, is monitored in real time through the monitoring module (including inclination sensor, speed sensor and pressure sensor). These data are transmitted to the control module in real time, and the control module makes judgments based on the preset algorithm and threshold to trigger the corresponding auxiliary function.

[0009] When the speed sensor detects that the patient's walking speed is lower than the preset threshold, and the pressure sensor detects that the upper limb grip force increases (indicating that the patient may feel fatigued), the control module will start the power part and drive the rest board to slide along the slide to a suitable position through the first chain to provide a resting platform for the patient. The roller design at the bottom of the rest board helps to reduce friction and make sliding smoother. The inclination sensor monitors the patient's body inclination angle in real time. When the angle exceeds the preset safety range, the control module will start the anti-dumping component to correct the patient's tilt state by adjusting the support force or position to prevent falling.

[0010] The above scheme has the following beneficial effects: 1. This solution, through real-time monitoring and intelligent response mechanism, can provide timely assistance when the patient feels tired or loses balance, effectively reducing the risk of falling and ensuring the patient's walking safety. Compared with traditional devices that only provide fixed assistance or lack intelligent response functions, this solution significantly improves the pertinence and timeliness of walking assistance, providing patients with safer and more reliable walking support.

[0011] 2. In this solution, the automatic adjustment function of the rest board can provide an immediate resting platform according to the needs of the patient, reduce fatigue during walking, and improve walking comfort. Traditional devices often lack such automatic adjustment functions, and patients need to find a resting place by themselves or rely on the assistance of others, which undoubtedly increases the walking burden and inconvenience of patients.

[0012] 3. The design of the gripping component of this solution not only helps patients maintain balance, but also encourages patients to do moderate upper limb strength exercises and enhance body coordination through feedback from pressure sensors. Compared with the gripping part of traditional devices that is only used as a simple armrest, the gripping component of this solution is more comprehensive and practical in function, providing necessary support and promoting physical rehabilitation and exercise for patients.

[0013] 4. In this solution, the control module has a high degree of personalized setting capability. It can be flexibly adjusted according to the patient's specific conditions (such as age, physical condition, walking habits, etc.), including monitoring thresholds, auxiliary functions, and rest board adjustment speed. Personalized settings not only improve the adaptability of the device, but also ensure that different patients can obtain the best walking assistance effect.

[0014] 5. In this solution, the overall design of the device of the present invention is compact and lightweight, easy to carry and move. Compared with the traditional device, which is often bulky and heavy, this solution pays more attention to the portability and ease of use of the device while maintaining comprehensive functions. This makes it easier for patients to carry and use the device of the present invention, improving its practicality and popularity in practical applications. At the same time, the operation of each functional module is simple and clear, and patients or family members can easily get started, improving the convenience of use.

[0015] Furthermore, the holding assembly includes a support frame, one end of the support frame is fixedly connected to the top of the mounting frame, a handle is installed at the end of the support frame away from the mounting frame, the handle is fixedly connected to a second chain, the second chain runs through the support frame, the second chain extends to the bottom of the mounting frame away from the handle and is fixedly connected to a baffle, a first spring is sleeved on the second chain, one end of the first spring is fixedly connected to the baffle, and the other end of the first spring is fixedly connected to the inner wall of the mounting frame.

[0016] Beneficial effects: One end of the support frame is fixedly connected to the top of the mounting frame to ensure the stability of the grip assembly. During walking, the patient can get additional support by holding the handle to reduce the risk of falling due to body imbalance. The handle is connected to the baffle at the bottom of the mounting frame through the second chain and is sleeved with a first spring. This design allows the handle to move up and down within a certain range to adapt to the grip strength requirements of different patients. For patients with weak grip, they can pull the handle by applying less force, and the elastic force of the first spring will provide a certain amount of assistance; for patients with strong grip, they can directly hold the handle tightly, and the first spring plays a role of buffering and stabilization. During walking, in order to maintain balance and stability, the patient needs to constantly adjust the strength of holding the handle. This repeated gripping and releasing action can exercise the patient's upper limb strength to a certain extent, and improve the coordination and stability of the body. The design of the first spring not only adapts to the grip strength requirements of different patients, but also can reduce the vibration and impact force during walking to a certain extent, and improve the comfort of walking. For elderly and frail patients, this design is particularly important, which can reduce their fatigue caused by long-term walking.

[0017] Further, the anti-dumping assembly includes a support rod, the support rod is hinged to the side wall of the mounting frame, a wedge is fixedly connected to one end of the support rod away from the mounting frame, a starting assembly is installed below the mounting frame, the starting assembly includes a cross bar, both ends of the cross bar are fixedly connected to the mounting frame, the height of the wedge is equal to the installation height of the cross bar, the cross bar is a hollow structure, a ball is rollingly matched in the cross bar, electric valves are installed on both sides of the ball, and the electric valves are connected to the control module signal; When the real-time angle data of the inclination sensor exceeds the threshold in the control module, the control module starts the electric valve on the same side as the abnormal data, and the electric valve opens, causing the ball to roll to the same side, thereby opening the support rod.

[0018] Beneficial effects: When the inclination sensor detects that the patient's body tilt angle exceeds the safe range, the control module can respond quickly and start the electric valve on the corresponding side. The opening of the electric valve allows the ball to roll to one side in the crossbar, thereby pushing the wedge and support rod to rotate and quickly deploy the support. This process is completed almost instantly, providing patients with immediate stability support and effectively preventing falls caused by loss of balance. This intelligent adjustment mechanism ensures that the device can adapt to the physical characteristics and walking habits of different patients, providing more personalized and precise anti-dumping support. The design of the anti-dumping component fully considers the compactness and easy maintenance of the structure. The hinged design of the support rod and the mounting frame allows the support rod to be easily folded and stowed when not needed, without taking up additional space. The timely response and intelligent adjustment mechanism of the anti-dumping component not only improves the patient's walking safety, but also reduces the potential risk of injury caused by falls. For elderly frail patients, this improvement in safety is particularly important, allowing them to walk more confidently and enjoy a freer life.

[0019] Furthermore, a fixing component is installed on the top of the support frame, and the fixing component includes an arc-shaped plate, and binding straps are fixedly connected on both sides of the arc-shaped plate. The binding strap on one side of the arc-shaped plate is fixedly connected with Velcro, and the binding strap on the other side of the arc-shaped plate is fixedly connected with an adjustment buckle.

[0020] Beneficial effects: The fixed component can fit the patient's upper limbs closely through the design of the curved plate, providing a stable support point for the patient. The curvature design of the curved plate is ergonomic, which can reduce the discomfort caused by long-term holding and improve the patient's holding comfort. The addition of the binding belt further enhances the stability of the grip, ensuring that the patient will not lose balance due to hand sliding or loosening during walking. Through the cooperation of Velcro and adjustment buckle, the fixed component can easily achieve personalized adjustment and adaptation. Patients can adjust the tightness of the binding belt according to their upper limb size and holding habits to ensure that the grip component can fit the upper limbs closely and provide the best support effect. This personalized adjustment mechanism enables the device to adapt to the needs of different patients and improves the comfort and convenience of use. The design of the fixed component not only enhances the stability of the grip, but also improves the safety of the patient. During walking, even if the patient loses balance due to fatigue or physical discomfort, the fixed component can reduce the risk of shaking and falling of the upper limbs through close fit and support, thereby effectively preventing accidents such as falls.

[0021] Furthermore, a foot pedal is installed at the bottom of the mounting frame. The foot pedal is a hollow structure. A number of massage balls are rotatably mounted on the top of the foot pedal. A second spring is fixedly connected inside the foot pedal. A transmission block is fixedly connected to one end of the second spring away from the foot pedal. The transmission block is fixedly connected to the baffle via a second chain on the side away from the second spring.

[0022] Beneficial effects: The massage ball on the top of the foot pedal is connected to the handle through a chain drive mechanism. When the patient pulls the handle, the massage ball rotates on the foot pedal, producing a slight massage effect on the sole of the foot. This massage helps to promote blood circulation and accelerate metabolism, thereby effectively relieving foot fatigue and muscle tension. This design is particularly important for elderly frail patients who stand or walk for a long time, and can significantly improve their walking comfort and physical comfort. Driving the rotation of the massage ball by pulling the handle not only provides patients with a novel experience, but also enhances their sense of participation and control. At the same time, this design also improves the safety of walking. When the patient feels tired during walking, the massage function can be triggered by pulling the handle, which can relieve fatigue to a certain extent and avoid the risk of falling due to fatigue. Since the rotation speed of the massage ball can be controlled by adjusting the pulling force of the handle, patients can customize a personalized massage experience according to their needs and comfort. This adjustability allows the device to adapt to the needs and preferences of different patients, improving satisfaction and comfort in use.

[0023] Furthermore, a through groove is provided on the rest board, and a seat cushion is fixedly connected to one side of the rest board.

[0024] Beneficial effects: The design of the rest board provides patients with a resting platform that is available at any time. When walking for a long time or feeling tired, patients can transfer part or all of their body weight to the rest board, which effectively reduces the burden on the lower limbs and relieves fatigue. The addition of the cushion further improves the comfort of the rest board, allowing patients to enjoy softer and warmer support when resting, improving the overall walking experience. The design of the cushion can be selected or replaced according to the patient's personal preferences and needs. For example, patients can choose cushions of different materials, thicknesses or with massage functions to further improve the comfort and health benefits when resting. This personalized design makes the device closer to the actual needs of patients and improves their satisfaction with use. Although the rest board has added a cushion and a through-slot design, the overall structure remains compact and lightweight. This makes the device still convenient to carry and store, and does not bring additional burden to patients or their families.

[0025] Furthermore, it also includes an early warning module, which includes an indicator light and a buzzer. The early warning module is connected to the control module signal. When the monitoring module detects that the patient's walking state is abnormal or there is a risk of falling, the control module controls the early warning module to start, the indicator light flashes and emits different colors of light to indicate different warning levels, and the buzzer emits an alarm sound.

[0026] Beneficial effects: The early warning module can quickly start and send out an early warning signal when the monitoring module detects that the patient's walking state is abnormal or there is a risk of falling. The flashing of the indicator light and the alarm sound of the buzzer can immediately attract the attention of the patient, family members or surrounding personnel, so that they can take quick action, such as coming forward to support or seek help, thereby effectively avoiding the occurrence of accidents such as falling, and greatly improving the walking safety of the patient. The indicator light design in the early warning module can emit different colors of light to indicate different warning levels. This intuitive display method enables patients and families to quickly understand the current level of danger and take corresponding levels of response measures accordingly. For example, when the indicator light emits red light, it may indicate that there is a serious risk of falling and immediate action is required; when it emits yellow light, it may indicate that there is a slight abnormality in walking and the patient needs to pay attention to adjusting the gait or rest. The activation of the early warning module not only reminds the patient of the current risks, but also enhances the vigilance of the patient and family members. In the long-term use process, this continuous reminder and warning helps to cultivate patients' more cautious walking habits and reduce the number of falls caused by negligence. At the same time, family members can also pay more attention to the patient's walking state and provide necessary support and help in time.

[0027] Furthermore, a storage box for storing personal items is provided on the mounting frame, and the storage box is detachably connected to the mounting frame.

[0028] Beneficial effects: The design of the storage box provides patients with a convenient space to store personal items. Patients can store their mobile phones, keys, wallets and other personal belongings in the storage box, so they don't have to worry about losing or being inconvenient to carry during walking. The detachable connection between the storage box and the mounting frame allows patients to easily remove or install the storage box and use it flexibly according to actual needs. The detachable connection design between the storage box and the mounting frame allows patients to choose storage boxes of different sizes, shapes or materials according to their personal preferences and needs. For example, patients can choose a storage box with dividers to better organize items, or choose a lighter material to reduce the overall weight. This personalized customization makes the device more in line with the actual needs of patients and improves satisfaction with use.

[0029] Furthermore, an auxiliary wheel is installed at the bottom of the mounting frame, and the auxiliary wheel is a universal wheel with a brake structure.

[0030] Beneficial effects: The auxiliary wheel is designed as a universal wheel, which means it can rotate in all directions, which allows patients to be more flexible and free when walking or turning. Whether walking in a straight line or turning, the universal wheel can provide a smooth movement experience, reducing the resistance and inconvenience of patients during walking. Although the universal wheel provides flexibility, the design with a brake structure ensures that the device can stop stably when needed. The brake structure can lock the wheel to prevent the device from moving uncontrollably, thereby improving the safety of the patient. This is especially important for elderly and frail patients, who may be more likely to fall due to loss of balance. The addition of the brake structure allows patients to easily control and park the walking aid device. When they need to stop or rest, the patient only needs to gently press the brake to ensure that the device is stable and motionless. This design not only improves the patient's control convenience, but also makes the device safer and more reliable when parked.

[0031] Furthermore, it also includes a wireless communication module, which is connected to the control module by signal, and is used to transmit the patient's walking status data and warning information to a remote mobile terminal in real time.

[0032] Beneficial effects: The wireless communication module enables the patient's walking status data and warning information to be transmitted in real time to a remote mobile terminal, such as a mobile phone, tablet or other device of a family member or medical staff. In this way, even if the patient is not within the direct line of sight of the family members or medical staff, they can understand the patient's walking condition and possible risks in real time. Once the warning information is received, the family members or medical staff can take quick measures, such as contacting the patient, going to the scene or notifying emergency services, to ensure the safety of the patient. Family members or medical staff can conduct detailed analysis and management of the data transmitted by the wireless communication module on the mobile terminal. They can view key indicators such as the patient's walking speed, number of steps, stride, and the triggering frequency and type of warning information. These data help family members or medical staff to have a more comprehensive understanding of the patient's walking ability and health status, so as to develop more personalized rehabilitation plans and management strategies.

[0039] The following is further described in detail through specific implementation methods: Embodiment 1:

[0040] As attached Figures 1 to 4As shown: A portable walking assist device for elderly and frail patients, including a mounting frame 1, on which are mounted a monitoring module for real-time monitoring of the patient's walking status and an auxiliary component for the patient to rest, the auxiliary component including a rest board 2, on which a through slot is provided, and a seat cushion is fixedly connected to one side of the rest board 2. The mounting frame 1 is a hollow structure, and a slide groove 101 is provided on the mounting frame 1, and the slide groove 101 is a T-shaped structure, the rest board 2 and the slide groove 101 are slidably matched, and a power part is installed at one end of the slide groove 101, in this embodiment, the power part is a motor 3, and a first chain 4 is fixedly connected to one side of the output shaft of the power part, and the first chain 4 is wound around the output shaft of the power part; the first chain 4 is fixedly connected to the bottom of the rest board 2 at one end away from the power part, and a plurality of rollers 201 are installed at the bottom of the rest board 2; The mounting frame 1 is provided with a gripping assembly for exercising upper limb strength and an anti-dumping assembly for preventing patients from falling. The gripping assembly includes a support frame 5, one end of the support frame 5 is fixedly connected to the top of the mounting frame 1, and the end of the support frame 5 away from the mounting frame 1 is provided with a handle 6, and the handle 6 is fixedly connected to a second chain 7, which runs through the support frame 5, and the end of the second chain 7 away from the handle 6 extends to the bottom of the mounting frame 1 and is fixedly connected to a baffle 8, and the baffle 8 and the rest board 2 are respectively placed at relative positions in the mounting frame 1. A first spring 9 is sleeved on the second chain 7, one end of the first spring 9 is fixedly connected to the baffle 8, and the other end of the first spring 9 is fixedly connected to the inner wall of the mounting frame 1.

[0041] The monitoring module includes an inclination sensor, a speed sensor and a pressure sensor. The inclination sensor and the speed sensor are both installed on the mounting frame 1, and the pressure sensor is installed on the gripping assembly. The monitoring module signal is connected to the control module: when the real-time speed data monitored by the speed sensor is lower than the threshold in the control module, and the real-time pressure data monitored by the pressure sensor is greater than the threshold in the control module, it means that the patient needs to rest, and the control module starts the power part and switches to the rest mode; when the real-time angle data monitored by the inclination sensor exceeds the threshold in the control module, it means that the patient has a tendency to fall, and the control module starts the anti-dumping assembly to adjust the tilt angle.

[0042] The anti-dumping assembly includes a support rod 10, which is hinged to the side wall of the mounting frame 1. A wedge is fixedly connected to one end of the support rod 10 away from the mounting frame 1. A starting assembly is installed under the mounting frame 1. The starting assembly includes a cross bar 11, both ends of which are fixedly connected to the mounting frame 1. The height of the wedge is equal to the installation height of the cross bar 11. The cross bar 11 is a hollow structure. Balls are rolled in the cross bar. Electric valves are installed on both sides of the balls. The electric valves are connected to the control module signal. When the real-time angle data of the inclination sensor exceeds the threshold in the control module, the control module starts the electric valve on the same side as the abnormal data, and the electric valve opens, causing the ball to roll to the same side, thereby opening the support rod 10.

[0043] The specific implementation process is as follows: when the patient performs lower limb training, the patient supports the elbow on the support frame 5 and holds the handle 6 with his hand. At this time, the patient can start walking or perform walking training. The monitoring module in the booster device monitors the patient's walking state in real time, including walking speed, body inclination angle, and pressure when holding the handle 6.

[0044] Normal walking state: If the patient's walking speed remains within the normal range set by the control module and the pressure of the grip handle 6 is moderate, it means that the patient is in good condition and can continue training. The rest board 2 is in a retracted state at this time and will not interfere with the patient's walking. The entire booster device can be easily moved on the ground through the rollers 201, making it convenient for the patient to move from one place to another for training.

[0045] When you need a break: When the speed sensor detects that the patient's walking speed is lower than the threshold in the control module, and the pressure sensor detects that the pressure of the grip handle 6 increases (indicating that the patient may feel tired or need support), the control module will determine that the patient needs to rest.

[0046] At this time, the control module starts the motor 3, and the motor 3 drives the rest board 2 to move upward along the slide groove 101 through the first chain 4. When it moves to the middle position, the rest board 2 rotates in an arc, and the rest board 2 is converted from a vertical state to a horizontal state. When the rest board 2 is placed completely horizontally, the cushion on the rest board 2 can provide a comfortable resting position for the patient, and the patient can sit down and rest.

[0047] Preventing falls: During walking, if the inclination sensor detects that the patient's body inclination drives the mounting frame 1 to incline at an angle exceeding the safety threshold in the control module, it indicates that the patient is at risk of falling.

[0048] The control module immediately activates the anti-dumping component and opens the electric valve on the same side as the abnormal data to make the ball roll to that side. The wedge design of the support rod 10 and the cross bar 11 ensure that the support rod 10 can be quickly and reliably deployed when needed. That is, through the impact of the ball, the wedge of the support rod 10 is knocked out of the cross bar 11, thereby pushing the support rod 10 to unfold, forming a stable support structure to prevent the patient from falling.

[0049] Upper limb exercises: When the patient sits on the cushion, the patient can exercise the upper limb strength by holding the handle 6 and pulling it appropriately. Due to the connection between the handle 6, the second chain 7 and the baffle 8, when the patient pulls the handle 6, the baffle 8 will also move, and the first spring 9 provides appropriate resistance, making the exercise more effective.

[0050] End of training: When the patient finishes the training or decides to stop, the motor 3 can be turned off manually or through the control module, and the rest board 2 can be manually retracted to the initial position, that is, the rest board 2 is pulled back to the initial position through the through slot. The support rod 10 of the anti-dumping assembly will also be automatically or manually reset to prepare for the next use.

[0051] Through the above-mentioned specific implementation process, the portable walking assist device for elderly and frail patients not only provides patients with a safe walking training environment, but also realizes real-time monitoring and automatic adjustment of patients' walking status through integrated monitoring modules and intelligent control functions, greatly improving the comfort and safety of training.

[0052] Embodiment 2:

[0053] Combined with the attached Figure 5 As shown, the difference from Example 1 is that a fixing component is installed on the top of the support frame 5, and the fixing component includes an arc-shaped plate 12, and binding straps 13 are fixedly connected on both sides of the arc-shaped plate 12. The binding strap 13 on one side of the arc-shaped plate 12 is fixedly connected with Velcro, and the binding strap 13 on the other side of the arc-shaped plate 12 is fixedly connected with an adjustment buckle.

[0054] The specific implementation process is as follows: gently lift the patient's arm and place it on the curved plate 12. Pick up the binding strap 13 with Velcro on one side of the curved plate 12. The binding strap 13 on this side is usually longer so that it has enough length to go around the patient's arm and stick to the Velcro. Pass the binding strap 13 over the arm, making sure it fits the arm tightly but not too tight to avoid discomfort or blood circulation obstruction. Pick up the binding strap 13 with an adjustment buckle on the other side of the curved plate 12, and pass the binding strap 13 with Velcro through the adjustment buckle. As needed, you can gradually tighten the binding strap, and after pulling it to the appropriate tightness, fix the binding strap 13 with Velcro. Make sure the arm is firmly fixed, but also avoid discomfort caused by overtightening.

[0055] After completing the initial fixation and adjusting the fastening, carefully check the firmness and comfort of the fixing assembly to ensure that the binding belt 13 does not twist or compress any sensitive part of the arm. If necessary, the position or tightness of the binding belt 13 can be slightly adjusted to ensure the best fixation effect and comfort. When it is confirmed that the fixing assembly has firmly and comfortably fixed the patient's arm, it can be considered that the fixation process has been completed. At this time, the patient can carry out relevant treatment, rehabilitation or rest activities under the support of the support frame 5.

[0056] Embodiment 3:

[0057] As attached Figure 5As shown, the difference from Example 2 is that a foot pedal 14 is installed at the bottom of the mounting frame 1, the foot pedal 14 is a hollow structure, a number of massage balls are rotatably engaged on the top of the foot pedal 14, a second spring is fixedly connected inside the foot pedal 14, and a transmission block is fixedly connected to the end of the second spring away from the foot pedal 14, and the side of the transmission block away from the second spring is fixedly connected to the baffle 8 through a second chain 7.

[0058] The specific implementation process is as follows: when the patient pulls the handle 6, the handle 6 drives the baffle 8 to move through the chain transmission mechanism. The movement of the baffle 8 is connected to the transmission block through the second chain 7, thereby transmitting the force to the transmission block. This chain transmission mechanism ensures the smooth transmission of force and the accuracy of control. When the transmission block is subjected to force, it pulls the second spring and produces elastic deformation, while pushing the massage ball to rotate on the top of the foot pedal 14. This rotation produces a slight massage effect, which helps to promote blood circulation and relieve foot fatigue.

[0059] When the patient releases the handle 6 or there is no force on it, the restoring force of the first spring 9 and the second spring will act on the baffle 8 and the transmission block respectively, so that they return to their initial positions. In this process, the transmission block pushes the massage ball to rotate again, achieving a continuous massage effect. The user can adjust the pulling force of the handle 6 according to his or her needs and comfort, thereby controlling the rotation speed of the massage ball. This adjustability enables the device to adapt to the needs and preferences of different users.

[0060] Embodiment 4:

[0061] As attached Figure 1 As shown, the difference from Example 3 is that it also includes an early warning module, which includes an indicator light and a buzzer. The early warning module is connected to the control module signal. When the monitoring module detects that the patient's walking state is abnormal or there is a risk of falling, the control module controls the early warning module to start, the indicator light flashes and emits different colors of light to indicate different warning levels, and the buzzer emits an alarm.

[0062] It also includes a wireless communication module (such as Bluetooth, Wi-Fi or LoRa, etc.), which is connected to the control module signal. The wireless communication module is used to transmit the patient's walking status data and warning information to a remote mobile terminal (smartphone, tablet computer or special medical equipment, etc.) in real time.

[0063] The specific implementation process is as follows: The early warning module is mainly composed of an indicator light and a buzzer, which are connected to the control module through a signal line or wirelessly. The indicator light uses a multi-color LED light that can emit different colors of light to indicate different early warning levels; the buzzer is used to sound an alarm to alert patients or surrounding personnel.

[0064] Different warning levels are preset in the control module, such as minor abnormality, moderate abnormality and severe abnormality. Each level corresponds to a different indicator light color and buzzer sound mode. For example, the indicator light may emit yellow light for minor abnormality, orange light for moderate abnormality, and red light for severe abnormality, accompanied by alarm sounds of different frequencies and volumes.

[0065] When the monitoring module detects that the patient's walking state is abnormal (such as too slow speed, too large inclination angle, etc.) or there is a risk of falling, the control module will determine the warning level based on the preset threshold and logical judgment, and control the warning module to start. The indicator light starts to flash and emit light of the corresponding color, and the buzzer sounds an alarm. The patient and the surrounding people can judge the current warning level by observing the color of the indicator light and listening to the alarm sound, and take corresponding countermeasures.

[0066] The control module encapsulates the patient's walking status data (such as speed, tilt angle, pressure, etc.) and warning information into a data packet, and sends it to a remote mobile terminal (smartphone, tablet computer or special medical equipment, etc.) through the wireless communication module. Install the corresponding application or software on the mobile terminal to receive and parse the data packet from the wireless communication module. The application displays the patient's walking status data and warning information in an intuitive way, such as charts, curves or text prompts. Medical staff or family members can view the patient's walking status data and warning information in real time through the mobile terminal, and take appropriate medical measures in time or remind the patient to pay attention to safety.

[0067] Embodiment 5:

[0068] As attached Figure 5 As shown, the difference from Example 4 is that a storage box for storing personal items is provided on the mounting frame 1, and the storage box is detachably connected to the mounting frame 1.

[0069] An auxiliary wheel 15 is installed at the bottom of the mounting frame 1, and the auxiliary wheel 15 is a universal wheel with a brake structure.

[0070] The specific implementation process is as follows: Select a suitable position on the mounting frame 1 to install the storage box. This position should be convenient for the patient to easily take and put items when using the walking aid, and will not interfere with other functions of the aid. A detachable connection method is adopted between the storage box and the mounting frame 1, such as screw fixing, snap connection or magnetic connection. This connection method allows the storage box to be easily removed from the mounting frame 1 when necessary, which is convenient for cleaning or replacement. For example: If a snap connection method is adopted, corresponding snaps and slots need to be designed on the storage box and the mounting frame 1, and the connection and disassembly are achieved by snapping in and out of the snaps. Install the storage box on the mounting frame 1 according to the determined connection method and position. Ensure that the connection is firm and reliable to avoid loosening or falling off during use. When using the walking aid, the patient can store personal items in the storage box. When the storage box needs to be cleaned or replaced, it can be easily removed from the mounting frame 1 according to the connection method.

[0071] The auxiliary wheel 15 is a universal wheel with a brake structure to ensure stability and safety during use. The universal wheel can easily change direction, so that the walking aid can move flexibly. Select a suitable position at the bottom of the mounting frame 1 to install the auxiliary wheel 15. This position should ensure that the walking aid can maintain balance and stability when moving. Use screws or other fixings to firmly mount the auxiliary wheel 15 on the mounting frame 1. When using the walking aid, the patient can control the movement of the auxiliary wheel 15 by operating the brake structure. The brake structure is usually designed in the form of a foot pedal 14 or a handle 6, and the braking function is achieved by stepping on or holding it.

[0072] When the walking aid device needs to be stopped for a rest, the patient can step on the brake pedal 14 or hold the brake handle 6 to stop the auxiliary wheel 15. By operating the auxiliary wheel 15 and the brake structure, the patient can easily move the walking aid to a desired position and ensure that it is stable and immobile when parked.

[0073] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
