Description

Wheelchair for critically impaired patients}

The present invention relates to a wheelchair for a patient with a mobility impairment, and more particularly, to a wheelchair for a patient with a mobility impairment that is simple in structure and more convenient to use so that the patient with difficulty in mobility can easily sit on a bed and safely use the toilet.

In general, wheelchairs used by people who have difficulty walking have the advantage of having wheels on both sides of a body configured in the form of a chair, so that a person sitting on the body can easily move by pushing the wheels or another person pushing the body.

However, in the case of patients with mobility impairments who have difficulty moving their bodies, it is very difficult to move from bed to wheelchair because they cannot move to a professional wheelchair, and someone else has to lift them and put them in a wheelchair. There was also a problem that put a lot of burden on me.

Therefore, in recent years, wheelchairs have been developed to easily seat these patients with mobility impairments, but these wheelchairs have a complicated structure and have a problem that it is very cumbersome for guardians to seat patients with mobility impairments.

Recently, in order to solve this problem, the 'upper body 110, the connecting member 120, and the lower body 130 are provided as shown in Utility Model Publication No. As a means of transportation for the mobility impaired,

The upper body 110 has a first horizontal frame 111a to which the first backrest 11 is mounted, a second horizontal frame 111b to which the second backrest 12 is mounted, and a first pedestal 13 to which The fourth horizontal frame 111d on which the third horizontal frame 111c and the second pedestal 14 are mounted and the first vertical frame connecting the first horizontal frame 111a and the third horizontal frame 111c ( 113) and a second vertical frame 114 connecting the second horizontal frame 111b and the fourth horizontal frame 111d are formed, and the first vertical frame 113 and the second vertical frame 114 are formed to be separated from each other, the first backrest 11 is formed with a handle 23 and a belt insertion portion 22 that can be used by caregivers, and the second backrest 12 has a handle that can be used by caregivers ( 24) and the belt fastening part 21 that is fastened when inserted into the belt insertion part 22 is formed, and the connecting member 120 includes first and second rotation frames 121 and 122 in which an insertion hole is formed In the lower body 130, the first and second vertical insertion members 132 into which the horizontal support member 131 and the first and second rotation frames 121 and 122 of the connecting member 120 are inserted, respectively, 133), foot rests 134 and 135, front wheels 136, and rear wheels 137, and the first seat 13 and the second seat 14 are attached to the belt insert 22. When the belt fastening part 21 is fastened, a through-hole (H) is formed, so that the caregiver can easily sit on the transportation means for the disabled even when the disabled person is sitting on the bed. It is easy to dismantle and combine so that it does not require a lot of space for storage, and a toilet bowl is provided on the seat, so it is possible to treat toilet in a sitting state without getting down from the means of transportation for people with reduced mobility during bathing. So it is very convenient to use.

However, despite the above configuration, it is inconvenient to adjust the height of the wheelchair appropriately, so the caregiver has difficulty in adjusting the height of the bed and the wheelchair, which makes it difficult to take care of the patient. Therefore, a wheelchair that is beneficial to the patient and caregiver is urgently needed. Edo manufacturers that produce wheelchairs, as well as related companies that handle, sell, and rent wheelchairs, are unable to solve the fundamental problem to solve this problem.

Therefore, there is a need for a new method capable of solving these problems.
