Description

Bath chairs that help immobile people bathe and move

technical field

The present invention relates to a welfare facility where caregivers (family members or care workers, etc.) can take care of immobile people (eg, sick, disabled, infirm, etc.) conveniently and comfortably.

In particular, the present invention relates to a bathing chair that assists an immobile person to bathe and move, and is characterized in that it enables a person who is immobile to take a bath in a third place (bathroom, lounge, etc.) instead of in a hospital room , or when the immobile person moves to a place for a meal, to watch television or a movie, or to change a bed cover, without lifting or lifting the upper body of the immobile person from the bed Easily move or bathe the immobile person.

For the convenience of the immobile person, most conventional hospital beds are provided with the rotation and orientation of the rotating handle on one side of the bed so that the upper part of the bed used to support the upper body of an immobile person is relative to the upper part of the bed used to support the upper body. An immobile person whose lower body is tilted at an angle so that they can stand upright or lie down.

When the above-mentioned conventional sick bed is adjusted to a certain angle upright on the upper side of the bed, it is impossible to make the lower body of the immobile person feel comfortable supported by the lower side of the bed, for example, it is impossible to make the legs of the immobile person relatively Bend the thighs. For the above reasons, when the upper side of the bed is adjusted to an upright state, the immobile person needs to maintain an uncomfortable sitting posture with legs stretched out. Furthermore, since the height of the bed cannot be adjusted, the immobile person cannot be moved to a treatment or examination bed having a different height. It is also impossible to temporarily move the immobile person to another bed or to a bathing place for taking a bath when the bed cover is changed. Especially, when the hospital bed is difficult to enter a narrow bathing place, the caregiver needs to carry the immobile person to the bathing place, so the caregiver's waist may be damaged or the immobilized person may become loose due to force. A moving person falls to the ground causing a more serious accident.

In order to solve the above problems, there is disclosed in the authorized patent document 1 (Korean Patent Registration No. 10-0292663) titled "Multifunctional bed for immobile persons", which is characterized in that when an immobile person wants to defecate or take a bath on the bed When operated by the user, the bed can be transformed into a chair or a bed.

However, in the multifunctional bed disclosed in Patent Document 1, when the immobile person needs to be moved to another bed, the caregiver still needs to pick up the immobile person.
