Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multifunctional sliding assistive cane. Background Technology

[0002] Existing crutches for ankle, foot, and lower leg injuries are categorized into hand crutches, elbow crutches, and axillary crutches. After ankle, foot, or lower leg sprains or fractures, patients often use one or two crutches to replace one leg for walking. However, patients may encounter the following problems when using crutches: First, lack of familiarity with the crutches can lead to falls, exacerbating the fracture or injury. Second, stride length affects the friction and angle between the crutches and the ground, making it difficult for patients to take excessively large strides, as this can also lead to slips and hinder recovery. Third, using crutches to replace one leg reduces walking speed, and the need for both hands to grip the crutches during walking disrupts daily life, especially for patients who require a long recovery period after fractures but cannot have dedicated caregivers. These patients also need to cook, do housework, and even go shopping. Hand-free crutches allow patients greater mobility and independence. Therefore, designing a multi-functional sliding assistive crutch that is convenient to use, frees up the hands, is safe and reliable, and includes some specialized tools is an urgent problem to solve.

[0003] To address the aforementioned problems, this invention provides a multifunctional sliding assistive cane. Summary of the Invention

[0022] To address the aforementioned problems, this invention provides a multifunctional sliding assistive cane that achieves convenient and fast walking, frees up the hands, and is safe and reliable.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] refer to Figures 1 to 2A multifunctional sliding auxiliary cane includes a sliding base, a support rod foldably mounted to the sliding base, a height adjustment rod mounted on the support rod, a handle mounted on the height adjustment rod, a support seat, and an angle adjustment device. The sliding base includes a front wheel connector at the end of the support rod, a rear wheel connector mounted on the support rod and located behind the front wheel connector, a front wheel mounted on the front wheel connector, and a rear wheel mounted on the rear wheel connector. This invention, by providing a sliding base, allows the user to kneel on the support seat and slide using the other foot, resulting in faster and more stable walking. Under normal circumstances, the knee can control the speed and direction of walking, thus achieving convenient and safe walking for the patient. The sliding base includes a support rod and a height adjustment rod. Furthermore, the height adjustment rod adjusts the height of the handle to accommodate different body heights, and the angle adjustment mechanism adjusts the angle of the support seat. When not in use, the cane can be folded and fitted close to the height adjustment rod.

[0025] refer to Figures 1 to 2 An angle adjustment device is disposed between the support base and the height adjustment rod.
