Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, specifically to a fall prevention device for hospital patient wheelchairs. Background Technology

[0002] A wheelchair is a chair equipped with wheels that can help replace walking. It is an important mobility tool for the injured, sick, and disabled to use for home rehabilitation, transportation, medical treatment, and outdoor activities. Wheelchairs not only meet the mobility needs of people with limb disabilities and those with limited mobility, but more importantly, they facilitate the movement and care of family members, and enable patients to exercise and participate in social activities with the help of wheelchairs.

[0003] Tilting often occurs during wheelchair use. While this is manageable with someone providing protection, it can be dangerous if a patient tilts and falls in a hospital, nursing home, or even outside the facility, especially if no one notices in time. Current wheelchair technology increasingly incorporates anti-fall structures, but most of these structures simply involve reinforcing the perimeter, adding auxiliary wheels at the front and rear, and adding simple guardrails on the sides. Once tilted, it is difficult for the patient to right themselves, and these structures cannot guarantee 100% fall protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel anti-fall device for wheelchairs used by hospital patients, addressing the shortcomings mentioned in the background art.

[0006] Furthermore, the wheelchair frame is equipped with backrests on both sides, and the top of the backrests is equipped with a control button that is electrically connected to the electric push rod, so that the patient can control the extension and retraction of the electric push rod.

[0007] Furthermore, the bottom of the pedal is equipped with an auxiliary ball bearing for easy movement when going downhill.

[0008] Furthermore, the bottom of the alarm box is equipped with an alarm buzzer and a warning light that are electrically connected to the electronic level, so as to provide an alarm to the surrounding area when tilting occurs.

[0009] Furthermore, the main fixed support column is provided with a first limiting groove, the first shock-absorbing support column extends into the first limiting groove and is connected to a first limiting plate, and the top of the first limiting groove is connected to a first damping shock absorber connected to the first limiting plate, which facilitates shock absorption when crossing damping strips, going uphill and downhill, and also provides shock absorption during daily movement.

[0010] Furthermore, the auxiliary fixed support column is provided with a second limiting groove, the second shock-absorbing support column extends into the second limiting groove and is connected to a second limiting plate, and the top of the second limiting groove is connected to a second damping shock absorber connected to the second limiting plate, so as to provide shock absorption performance for the rear anti-fall support wheel when going uphill and tilting backward.

[0011] The advantages of this utility model's anti-fall device for hospital patient wheelchairs compared to existing technologies are as follows: This utility model uses auxiliary rollers set in the rear auxiliary wheels and front foot pedals to prevent tilting forward or backward when going up or down slopes. At the same time, the electric push rods on both sides can be controlled by the patient to straighten the wheelchair when it tilts left or right. Additionally, the alarm box on the rear side can sound an alarm when an accidental tipping occurs. Attached Figure Description
