Description

A new type of non-magnetic wheelchair transfer bed

technical field

The invention relates to the technical field of medical equipment, in particular to a new non-magnetic wheelchair transfer bed.

Background technique

In daily life, wheelchairs can provide a more convenient way of moving for the elderly with inconvenience or those with lower limb disabilities, reducing the trouble caused by inconvenient movement and reducing the burden of caregivers. Wheelchairs are indispensable medical equipment in hospitals. , widely used, and can provide patients with convenient mobile tools and resting places. At the same time, the non-magnetic wheelchair transfer bed is also used in the MRI examination room of the hospital. When the inspection instrument is working, a strong magnetic field will be generated, and the magnetic material will be adsorbed. and inspection of the instrument resulting in injury and damage.

The wheelchair currently used is only a means of transportation and can only provide mobility. In the daily life of the patient, in addition to the assistance of the wheelchair when moving, it is still necessary to change other places when resting and sleeping, such as getting in and out of bed. And other movements, which add a lot of unnecessary trouble for the elderly with limited mobility or people with lower limb disabilities. Ordinary non-magnetic wheelchairs are generally made of non-magnetic stainless steel materials or plastic materials. Non-magnetic stainless steel materials will be gradually demagnetized during long-term MRI examinations, while plastic materials will become brittle and fragile during long-term use. The stability is poor and the firmness is low, which brings great security risks to users. In addition, ordinary wheelchairs are used in public places for a long time. Different people touch, and bacteria spread infection. It is not easy to disinfect. It is necessary to disassemble the wheelchair seat and backrest for disinfection, which increases the workload of caregivers.
