Description

An orthopedic wheelchair for preventing backward tilt

technical field

The invention relates to the technical field of orthopedic wheelchairs, in particular to a recoil-preventing wheelchair for orthopedics.

Background technique

Wheelchairs are chairs equipped with wheels that can help replace walking, and are divided into electric and manual folding wheelchairs. It is an important mobile tool for home rehabilitation of the wounded, the sick, and the disabled, turnover transportation, medical treatment, and outing activities. The wheelchair not only meets the needs of the physically disabled and people with reduced mobility, but more importantly, it is convenient for family members to move and take care of the sick. Patients use wheelchairs for physical exercise and social activities.

Among orthopedic patients, some patients with disabilities and fractures in their legs need to use wheelchairs as moving tools. In the actual use of wheelchairs in the prior art, although anti-tilt wheels are installed to prevent backward tilting, they do not change In the case of the user and the overall center of gravity of the wheelchair, it is still easy to fall backwards, and the existing wheelchair sitting posture is uncomfortable to use for a long time and is likely to cause diseases such as lumbar disc herniation. In addition, when the existing wheelchair is used outdoors , can not keep out the rain for the user, and the rainwater will pour on the user, which will easily cause the user to catch a cold and the patient's inflammation and infection.

In order to solve the above problems, the present invention proposes an orthopedic recoil-preventing wheelchair.
