Description
Technical field
The invention belongs to assistive device field, it is related to a kind of wheelchair, specifically a kind of seat with pressure sore prevention function is wide can
Mode fully collapsible invalid's chair.
Background technology
As medical special equipment, its function sets service object as specific crowd to wheelchair, to meet the need that they ride instead of walk
Will, of crucial importance for the people of inconvenient walking, its not still a kind of walking-replacing tool, it is often more important that can allow limbs disability
Personage participates in every social activities, and such as trip is travelled faraway, goes window-shopping and do shopping or participate in sports activites, and can not only experience them
Life, but also them can be allowed to participate in social activities in power etc..
At present, wheelchair on the market is mostly the structure of the wide size of fixed seat, although so going for a part makes
With colony, but build can be caused partially fat or partially thin individuals with disabilities is using uncomfortable, and customized wheelchair selling at exorbitant prices,
Great financial burden can be brought to user, also customized wheelchair can be because the difference of own service level and existing
There is the deficiency of e measurement technology, it is impossible to allow user to be verified in the very first time to measurement data, and cause user to customization
Wheelchair still have certain dissatisfaction, especially winter user wear clothing it is more in the case of, be even more extremely uncomfortable；And
And the function of Bedsore prevention is not present in current wheelchair, so-called pressure sore refers to individuals with disabilities, and the patient of especially vertebra paralysis exists
During use, can because can not adjustment position and keep relatively-stationary sitting posture for a long time, cause local organization for a long time hold
The blood circulation at compression position is obstructed again, formed by pressure ulcer, scale can be caused to differ the body of patient itself
Damage, can also live to it and cause very big inconvenience；The patient of vertebra paralysis has to Bedsore prevention when using wheelchair,
And the method for Bedsore prevention usually requires patient itself with being supportted for a long time with the help of the caregiver such as hand or layman, friend
Body is played, makes the blood circulation at normal compression position, but patient is when itself props up body for a long time, what arm strength was not enough
Words, easily cause patient and drop wheelchair, there is potential safety hazard, although and body can be propped up with the help of caregiver,
It is to need to keep for a long time, extremely arduously, and needs to carry out help support regularly to patient, caregiver is caused greatly
Inconvenience.
The content of the invention
A kind of wide adjustable folding wheel of the seat with pressure sore prevention function is provided the present invention be directed to the deficiencies in the prior art
Chair, using the wide structure of adjustable seat, is easy to user to be adjusted according to the comfort level of itself is wide to the seat of wheelchair, solves
Can not adjustment seat it is wide and cause the problem of user causes discomfort when taking wheelchair, and by pressure sore prevention device can be effectively
Allow user itself that body is propped up and is supported, reach the purpose of Bedsore prevention.
The technical solution adopted in the present invention：
A kind of wide adjustable fully collapsible invalid's chair of seat with pressure sore prevention function, including two chair frames, set seat between chair frame
