Description

Technical Field

[0001] This utility model belongs to the field of wheelchair technology, specifically a multi-functional transfer chair for lower limb fractures. Background Technology

[0002] After a lower limb fracture, a wheelchair is an important assistive tool. Its role is mainly reflected in ensuring patient safety, promoting rehabilitation, and improving quality of life. After a lower limb fracture, the fracture site needs to be strictly protected from weight-bearing or stress, otherwise it may lead to fracture displacement, loosening or breakage of internal fixation, or even delayed or nonunion. A wheelchair can reduce the weight-bearing on the lower limb.

[0003] After a fracture, patients often experience limited lower limb mobility and decreased balance, making them prone to falls when standing or walking, which can cause secondary damage to the fracture site. Wheelchairs provide a stable support platform, effectively avoiding the risk of falls, and are especially suitable for short-distance movement in home, outdoor, and other settings.

[0004] After prolonged use, it was found that traditional wheelchair-to-bed transfers require a caregiver to assist the patient, a process that is not only cumbersome and time-consuming, but also puts medical staff under strain, making it difficult to supervise the patient. Furthermore, in cases of lower limb fractures, the patient is prone to displacement due to repeated movement. This new method aims to prevent patients from falling out of bed or experiencing other risks during transfers, thus ensuring a comfortable rest.

[0005] Therefore, this utility model provides a multifunctional transfer chair for lower limb fractures. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
