[0002] A walker is a device that assists walking, designed to provide support and balance for people with limited mobility, helping them walk more safely and independently. With the promotion of early accelerated rehabilitation after surgery, patients who need to get out of bed early have higher safety requirements. Frame-type walkers can play a role in preventing falls and providing protection for these patients during rehabilitation exercises.

[0003] However, existing walkers are semi-enclosed structures and cannot provide comprehensive protection for patients while walking. This is especially true for patients at high risk of falls, such as those experiencing postoperative weakness, pain, or postural hypotension. During exercise, these patients can easily experience discomfort such as hypotension and syncope, causing them to lean forward or backward, resulting in falls and serious consequences such as fractures or cerebral hemorrhage. Therefore, the protective features of traditional walkers are incomplete and cannot effectively reduce the risk of falls and the resulting injuries.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0033] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0034] The utility model provides Figure 1The device, shown here, provides support and balance for people with limited mobility, helping them walk more safely and independently. For example, it can prevent falls in the event of fainting during exercise, especially for patients recovering from leg surgery. The device's main components include a walker frame 1 and a seat cushion 2. The walker frame 1 assists and protects the patient while walking, while the seat cushion 2 supports the patient when fatigued or experiencing fainting. The walker frame 1 is provided with two grip tubes 11 on the left and right sides. The patient holds the grip tubes 11 on the left and right sides with both hands to maintain balance when walking. The front and rear ends of each grip tube 11 respectively form a front curved portion 12 and a rear curved portion 13. The front curved portion 12 and the rear curved portion 13 can prevent the patient from being bumped. The front curved portions 12 and the rear curved portions 13 extend downward to form a front leg tube 14 and a rear leg tube 15 respectively. A switchable safety door 17 is provided between the front leg tubes 14 on both sides, and a rear cross tube 16 is provided between the rear leg tubes 15 on both sides; the seat cushion 2 is detachably connected to the walker frame 1; the two rear leg tubes 15 and the two front leg tubes 14 can form a stable support structure to maintain the stability of the patient when walking, effectively prevent tilting, and avoid excessive support columns causing the structural weight of the entire walker frame 1 to be too heavy.

[0035] Elastic buffers 18 are installed at the bottom ends of the two rear legs 15 and the two front legs 14. These buffers are designed to absorb pressure on the two rear legs 15 and the two front legs 14 and are retractable and adjustable. These buffers provide a certain degree of cushioning when the walker frame 1 moves, reducing the impact force when the walker frame 1 contacts the ground. This can alleviate the vibration felt by the patient's hands and improve the patient's walking experience.

[0036] Further, such as Figure 1 As shown, a movable groove 19 is formed between the two rear leg tubes 15 and the two front leg tubes 14, and the seat cushion 2 is disposed in the movable groove 19. It can be understood that the walker frame 1 has a hollow frame structure. When in use, the patient is positioned in the middle of the walker frame 1, and the walker frame 1 surrounds the patient to provide protection.

[0037] Further, such as Figure 1 and Figure 3 As shown, the seat cushion 2 is configured as a bridge-type seat cushion structure. The front end of the seat cushion 2 is detachably connected to the grip tube 11 via a connecting strap 21, and the rear end of the seat cushion 2 is connected to the rear cross tube 16. In some embodiments, the seat cushion 2 is configured as a fabric structure. The fabric seat cushion 2 has good softness and does not hinder the patient's thighs during walking.

[0038] The key feature of the bridge-style seat cushion is the arched or raised structure in the middle, resembling a bridge. This structure provides excellent support, particularly in the middle area, effectively distributing pressure across the body, reducing excessive pressure on specific areas of the buttocks and helping to prevent pressure sores. It also enhances ventilation and improves posture, helping to guide the user in maintaining a correct sitting position and relieving pressure on the waist and spine. For those who require long-term wheelchair use, the bridge-style seat cushion structure can improve their quality of life and reduce the discomfort associated with prolonged sitting.

[0039] Further, such as Figure 1 and Figure 4 As shown, a main unit 3 is provided on the walker support 1 , and a display screen 31 is provided on the main unit 3 . The display screen 31 is used to display the patient's movement status.

[0040] Furthermore, the host 3 is also provided with buttons, a battery, and a speaker, wherein the speaker can prompt the protrusion condition by generating an alarm sound.

[0041] Further, such as Figure 1 and Figure 2 As shown, a first pressure sensor 183 is disposed within the elastic buffer 18, and the first pressure sensor 183 is electrically connected to the host 3. Each time the walker frame 1 moves and contacts the ground, the elastic buffer 18 contracts under the pressure, thereby triggering the first pressure sensor 183, thereby collecting the patient's movement data.

[0042] Further, such as Figure 1 and Figure 5 As shown, a safety ball 171 is provided at the upper end of the safety door 17, and a cushion 161 is provided on the rear transverse tube 16. Both the safety ball 171 and the cushion 161 provide excellent elastic cushioning. If a patient faints or becomes unstable and falls forward or backward, the safety ball 171 or the cushion 161 on the safety door 17 can effectively support and protect the patient, preventing them from falling. This provides comprehensive protection.

[0043] Further, such as Figure 1 and Figure 5As shown, the safety balloon 171 is configured as a cylindrical airbag structure. A second pressure sensor 172 is installed both within the safety balloon 171's inflation chamber and on the back cushion 161. The second pressure sensor 172 is used to detect the air pressure within the inflation chamber of the safety balloon 171 and is electrically connected to the main unit 3. The cylindrical airbag structure provides excellent elastic cushioning and is lightweight, thus not adding excessive weight to the walker frame 1. The air pressure within the inflation chamber of the safety balloon 171 changes with the applied pressure. Therefore, the second pressure sensor 172 within the inflation chamber can sense whether the airbag is being squeezed.

[0044] Further, such as Figure 1 and Figure 2 As shown, the elastic buffer member 18 includes an upper column 181 and a lower column 182. The upper end of the upper column 181 is connected to the bottom of the rear leg tube 15 and the front leg tube 14. The upper column 181 defines a receiving cavity 1811, which opens downward. The lower column 182 is slidably connected to the receiving cavity 1811. The upper column 181 and the lower column 182 are slidably connected through the receiving cavity 1811.

[0045] An elastic member 1812 is disposed within the accommodating chamber 1811. The two ends of the elastic member 1812 abut against the upper column 181 and the lower column 182, respectively, so that the lower column 182 always has elastic force in the extending direction of the accommodating chamber 1811. A first pressure sensor 183 is disposed at either end of the elastic member 1812.

[0046] Further, such as Figure 2 As shown, an anti-skid pad 1821 is provided at the bottom of the lower column 182. The anti-skid pad 1821 is configured as a rubber material structure. The anti-skid pad 1821 can prevent the walker frame 1 from slipping when the patient walks.

[0047] Further, such as Figure 1 As shown, the outer walls of the two grip tubes 11 are covered with anti-slip sleeves 111. The walker frame 1 is configured as an aluminum alloy frame structure. The anti-slip sleeves 111 effectively prevent slipping. Preferably, the anti-slip sleeves 111 can be configured as an elastic material structure. The aluminum alloy frame structure is lightweight, effectively reducing the structural weight of the walker frame 1, improving the user experience for patients.

[0048] In summary, this application provides a fall-prevention walker. During use, the patient stands, enters through the safety door 17, holds the grip tube 11 with both hands, and then locks the safety door 17 before walking. If the patient experiences a faint, the left and right grip tubes 11, the safety door 17, and the rear cross tube 16 provide all-around protection. If the patient faints, they can only fall onto the seat cushion 2, effectively preventing them from falling.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
