Description

床上靠背支架 技术领域  TECHNICAL FIELD
本发明涉及床上靠背支架。  The present invention relates to a bed backrest support.
背景技术  Background technique
卧床休息的病人，长时间卧床后会感到全身疲乏。往往需要坐靠在床上休 息一下， 用餐时更需将上身向前倾斜一定角度以便食物下咽。这时往往需要护 理人员将被子等堆放在病人背后， 使其成半卧姿式， 不仅堆放被子比较麻烦， 时间稍长， 背后的被子被压陷， 支撑作用减弱， 病人上身后仰， 还需将被子再 重新堆放， 非常烦琐。 已有的病床可以将床头部分适当摇起， 但因床上的被子 较厚， 使床头抬起的角度被削弱， 呈斜坡状， 病人往往会下滑， 不能舒适地坐 于床上。  Patients who are in bed will feel tired after being in bed for a long time. It is often necessary to sit back and rest in bed, and at the same time, you need to tilt your upper body forward at a certain angle so that the food can be swallowed. At this time, caregivers often need to stack quilts and other patients in a semi-recumbent position. Not only is it more troublesome to stack quilts, it takes a little longer, the quilts behind them are crushed, the support function is weakened, and the patient leans back and up. Putting the quilt back on again is very cumbersome. Existing beds can be properly shaken at the head of the bed, but because of the thick quilt on the bed, the angle at which the head of the bed is lifted is weakened, and the patient tends to slide down and cannot sit comfortably on the bed.
发明内容 Summary of the Invention
鉴于上述原因，本发明的目的在于提供一种床上靠背支架。当病人需要在 床上坐起时， 将该支架放在病人背后作为靠背之用， 其角度可调， 使病人坐于 床上感到舒适不易下滑。 不用时可将其取下， 折叠起来， 便于存放。' - 为实现上述目的，本发明采用以下技术方案： 一种床上靠背支架， 它包括 直立的靠背和框架式底座； 所述底座置于所述靠背的后面， 靠背下部与底座通 过转角定位机构铰接在一起。  In view of the foregoing, an object of the present invention is to provide a bed backrest support. When the patient needs to sit up on the bed, the bracket is placed on the back of the patient as a backrest, and the angle is adjustable, so that the patient feels comfortable on the bed and does not fall easily. It can be removed when not in use and folded for easy storage. '-In order to achieve the above-mentioned object, the present invention adopts the following technical solutions: A bed backrest bracket comprising an upright backrest and a frame-type base; the base is placed behind the backrest, and the lower part of the backrest and the base are hinged through a corner positioning mechanism Together.
所述转角定位机构可以是离合器式转角定位机构，也可以是电动式转角定 位机构， 形式多样。  The rotation angle positioning mechanism may be a clutch rotation angle positioning mechanism or an electric rotation angle positioning mechanism in various forms.
本发明床上靠背支架还可以设置有扶手， 扶手上设置桌面。  The bed back support of the present invention may further be provided with an armrest, and a tabletop is provided on the armrest.
本发明床上靠背支架还可以匹配各种功能各异的康复性身体活动器。 本发明床上靠背支架，在病人坐起后，放于病人背后。靠背后面的底座后 端支顶于床头处， 通过调整转角定位机构使靠背直立或稍向后倾。 由于本发明 靠背如沙发或软椅的靠背一样， 病人依靠时会感到舒适， 并且靠背可根据病人 需要调整倾斜度， 使用非常方便， 能使病人久坐而不易下滑。在病人需要躺卧 时， 可将本支架由床上取下， 折叠放置， 操作简单。  The bed back support of the invention can also be matched with various rehabilitation physical activity devices with different functions. The backrest support of the bed of the present invention is placed on the back of the patient after the patient sits up. The back end of the base on the back side is supported at the head of the bed, and the backrest is upright or tilted slightly backward by adjusting the angle positioning mechanism. Since the backrest of the present invention is like the backrest of a sofa or a soft chair, the patient will feel comfortable when relying on it, and the backrest can be adjusted inclination according to the needs of the patient. It is very convenient to use and can prevent the patient from sitting for a long time without falling down. When the patient needs to lie down, the bracket can be removed from the bed, folded and placed, and the operation is simple.
